Follow all the instructions in this manual carefully and heed all safety precautions. Improper use of this diving helmet could result in serious injury or death.
Kirby Morgan Dive Systems, Inc. (KMDSI) warns all divers who use Kirby Morgan diving helmets or masks to be sure to use only KMDSI original parts from a KMDSI authorized dealer. Although other parts, O-rings and ttings may appear to t your Kirby
Morgan diving helmet or mask, they may not be manufactured to the same standards
maintained by KMDSI. The use of any parts other than KMDSI original parts may lead to
equipment failure and accidents.
Diving in waters that are chemically, biologically, or radiologically contaminated is extremely hazardous. Although Kirby Morgan diving helmets may be adapted for use in
some contaminated environments, special training, equipment, and procedures are
necessary. Do not dive in a contaminated environment unless you have been thoroughly
trained and equipped for this type of diving.
Read this manual before using or maintaining the helmet, even if you have experience with other diving helmets. If
you have purchased the helmet new from a dealer, be sure to send in the warranty registration card so we may
keep you informed of any safety notices that affect this product. If you resell or loan this helmet to another diver,
be sure this manual accompanies the helmet and that the person reads and understands the manual. In addition to the
manual a log book should be used to log all repairs, maintenance and use.
This helmet was completely checked and should be ready to dive as it was shipped
from the factory. However, it is always the diver’s responsibility to check all the components of the helmet prior to diving.
Diving is a life threatening occupation. Even if you do everything right you can still be
killed or injured. None of the models of Kirby Morgan helmets or masks can prevent accidents, injuries or death due to improper training, poor-health, improper supervision,
improper job requirements, improper maintenance or acts of God.
Any and all berglass repairs done to this helmet MUST be done by a KMDSI factory
trained repair facility. Painting is not recommended by KMDSI. Furthermore, many diving companies will not allow painted helmets to be used because painting can mask
previous berglass damage. KMDSI certied technicians are not responsible for certifying helmets free from damage during annual overhauls.
Helmet shells can be re-gel coated by authorized/certied KMDSI trained technicians
that have received berglass training by KMDSI. Helmets that are to be painted for
cosmetic purposes, should be rst, certied free of berglass damage by an authorized
KMDSI technician certied in berglass repair. A log entry should be made in the helmet log that the helmet was free of damage prior to painting. Keep in mind other KMDSI
technicians can refuse to work on helmet shells that have previously been painted or
repaired by non KMDSI certied persons.
This manual is supplied to the original purchaser of this helmet. If you have any questions about the use of the helmet
or you need another copy of this manual, contact KMDSI or your nearest KMDSI dealer. It may also be downloaded
free from the KMDSI website at www.KirbyMorgan.com.
KMDSI helmets and masks are intended for underwater use only and should only be
used by qualied divers that have received proper training in the use of this type of
equipment. KMDSI helmets and masks should not be used or worn without the appropriate life support systems, such as air or gas supplies and support personnel as described in this manual.

General Information KMDSI Products
1.1 Introduction
The Kirby Morgan Corporation was started in 1965.
The copper and brass “Heavy Gear” or “Standard
Dress” helmets were the first helmets manufactured
by the company. Over the years Kirby Morgan designed, manufactured and sold many different helmets
and masks for commercial divers.
Staying active in commercial diving has contributed
to the successful design innovations of KMDSI products. This may be the primary reason for the acceptance of our designs by professional divers.
Bev Morgan has designed more than fifty-seven diving helmets and over 40 diving masks. All employees
of KMDSI participate as part of the Kirby Morgan
design team. It would not be possible for us to supply the commercial, military, scientific, and public
service diving industries with our equipment, without
the team of people that make up Kirby Morgan Dive
Systems, Inc. (KMDSI)
We feel it is important for the reader to understand
that we at KMDSI consider ourselves as only part
of the process along the path in diving equipment
design. We welcome all input from our customers.
The thinking of many good divers, diving equipment
engineers, diving medical specialists, diving organization administrators and their supporting personnel
has contributed to the current state of the art of diving.
Each piece of gear we manufacture has in it some of
the thinking of those who have gone before us. To
all those people who gave something of themselves
to the men and women who work underwater, we
express a thank you.
We have a strong commitment to providing the best
diving equipment and service possible. This thinking
has been the policy of Kirby Morgan Dive Systems,
Bev Morgan, Chairman of the Board Kirby Morgan
Dive Systems, Inc.
Inc. and we will continue to take this approach to
our work.
Our extensive dealer network makes it easy to obtain
genuine Kirby Morgan replacement parts, as well as
technical assistance worldwide.
KMDSI has always concentrated on designing and
manufacturing diving equipment that allows most
repairs, inspections, and all routine maintenance to
be performed by the user. Most routine preventative
and corrective maintenance can be accomplished by
the user utilizing this manual, the KMDSI Tool Kit
(P/N 525-620) and common hand tools. Technician
training is available through Dive Lab Inc. Information can be obtained on line at www.divelab.com or
by telephone at 850-235-2715.
The EXO Full Face Mask is designed for both
surface supplied and scuba diving. By enclosing the
divers eyes, nose and mouth, the EXO permits nearly
normal speech when used in conjunction with most
wireless, and all hard wire underwater communication systems.
The EXO BR (BALANCED REGULATOR) shown
here is designed to meet or exceed recommended
performance goals in both scuba and surface supplied
modes and is
approved. It meets and surpasses
European standards for regulator performance.
The KMB 18B Band Mask frame is constructed of
hand laid fiberglass. The head harness is a molded,
strong tear resistant neoprene rubber.
The hood, which attaches to the mask frame with
welded stainless steel bands, provides warmth for
the divers head as well as pockets for the earphones.
The communications connections can be either a male
waterproof plug in type or bare wire posts. Both this
mask and the KMB 28B feature the new Tri-Valve™
Exhaust System.
The KMB 28B Band Mask (not shown) is very simi-
lar to the KMB 18, with many parts on the KMB 18B
being interchangeable with the KMB 28B. The major
difference between the 18 and 28 is the material of the
mask frame itself. The KMB 18 has a fiberglass frame
(yellow) while the KMB 28B frame is an extremely
durable injection molded plastic (black).
Other differences include:
1) The main exhaust body of the KMB 28 is part of
the frame itself and uses a #545-041 main exhaust
cover
2) no comfort insert is required on the 28
3) the face ports for the 18 and the 28 differ slightly in size.

The Balanced Regulator helps reduce the work of
breathing for the diver by balancing the intermediate
air pressure against the valve sealing pressure inside
the regulator. This enables the regulator to instantly
adjust to changes in line pressure. The balanced
regulator is adjustable for a wide range of intermediate pressures between 90 PSIG – 250 over ambient
pressure (6.2 – 17 bar).
Both models have a modular communications design
that permits rapid and simple maintenance. The
optional Hard Shell provides surfaces for mounting
lights, cameras etc.
The SuperMask M-48 is an innovative new design
in a full-face mask. It provides the diver with all the
comfort of a full-face mask with the convenience
of changeable second stage regulators as well as the
ability to use a snorkel without having to remove
the mask.
The mask is comprised of two major components,
the mask frame and the interchangeable lower pod.
The removable lower pod is a feature unique to the
SuperMask full-face mask. When diving, the pod is
easily removed and replaced on the mask, providing
the diver the capability to buddy-breathe, snorkel,
use an octopus or perform an “in water” gas switch.
With the pod sealed to the mask, the flexible, silicone
pod cover allows the diver to quickly place the regulator mouthpiece into the mouth or dive with it free of
the mouth for communications. With the mouthpiece
in, the regulator may be used without the pod being
sealed to the mask.
KMACS-5
w/ Communications
The Kirby Morgan Air Control System-5 (KMACS)
is a lightweight, portable control box for use in surface supplied air diving operations. The KMACS-5
controls the diver’s air supply, communications and
monitors the diver’s depth. It allows two divers clear
push-to-talk (two wire) or round robin (four wire)
communications. The KMACS-5 is also available
without communications.
The air supply can be either from a low-pressure
compressor or high-pressure cylinders. The adjustable first stage regulator reduces the high-pressure
air and supplies low pressure through the umbilical
to the diver’s breathing system.
High pressure yokes permit U.S. standard scuba
cylinders or DIN equipped cylinders to be used. Lowpressure air supply fittings allow for a compressor to
be used as the primary air source.
The mask may also be used surface supplied when
used with the proper accessories. We are currently
developing several different pod configurations for
both open circuit and rebreather use. For further
information, see the Frequently Asked Questions
(FAQ) area on
our web site at www.KirbyMorgan.
com/FullFaceMasks/M48.html.
A complete pneumo system with dual reading gauges
(both US Standard and Metric) is provided for each
diver’s air, as well as a shut-off/bleed system that uses
two high-pressure feed lines which allows changing
of used cylinders without interruption of the diving
operation. Optional shut off valves allow the isolation
of each diver’s air supply.
The Communication Set is a multipurpose intercommunication system that provides reliable and clear
communications between a topside operator (tender)
and one or more surface-supported divers, recompression chambers, or other submersible systems.
All Kirby Morgan diving helmets and masks are
manufactured by Kirby Morgan Dive Systems, Inc.
(KMDSI). Each step of the manufacturing process is
carefully controlled to assure the customer of a high
quality, durable helmet that will function properly
for many years.
There are eight models of Kirby Morgan diving helmets currently in production. They are the SuperLite
17B, (MK-21- U.S. Navy version), SuperLite
the SuperLite
37SS, 47, 57, and 77. All are

and quickly set a new standard for diving helmet
design. Many large and small commercial diving
companies, military organizations, scientific divers,
and public safety divers are successfully using this
design around the world. This helmet is
marked.
®
17C
®
The SL-17 A/B helmet system consists primarily of
two major components: the neck dam/yoke assembly,
and the helmet. To don the helmet, the diver first
slips the angled neck dam with the attached yoke over
their head. The helmet is lowered onto the diver’s
head with the help of a tender, then the yoke hinge
tab is hooked onto the alignment screw on the rear
weight. The neck clamp is then slipped onto the helmet and locked. The locking system not only seals
-
the neck dam to the helmet but also secures the front
of the yoke, fastening the helmet to the diver’s head.
The SuperLite
®
-17A/B shares many common breath-
ing system parts with all Kirby Morgan helmets and
masks. The breathing system was man-tested to
1600 FSW by the University of Pennsylvania and
approved by the U.S. Navy for surface-supplied diving to 190 FSW with air and 300 FSW with mixed
gas. It surpasses all requirements of all governing
agencies and it is approved for commercial diving
through out the world.

The Kirby Morgan 37 Commercial Diver’s Helmet
represents what we at Kirby Morgan consider to be
a turning point in modern diving helmet design. The
helmet consists of two major assemblies: the helmet
shell/helmet ring assembly and the neck dam/neck
ring assembly.
The helmet comes with the large tube SuperFlow
®
350 adjustable demand regulator which provides an
easier breathing gas flow during peak work output.
A quick change communications module is available
with either bare wire posts or a waterproof connector.
The helmet ring houses the sealed pull pins and provides protection for the bottom end of the helmet. The
diver is also provided with an internally adjustable
chin support. This custom fit and balance seats the
helmet comfortably for long periods of time even
when working in the face down position.

The Kirby Morgan 47 offers the ultimate in a high
performance breathing regulator. This helmet has an
entirely new breathing system, oral nasal mask, and
water ejection system. The REX Demand Valve, with
it’s fully adjustable balanced piston is a breakthrough
design that exceeds the requirements of all government or other testing agencies.
It has the best work-of-breathing performance when
compared to ANY other commercial diving helmet.
The Kirby Morgan 47 Dive Helmet has been tested
and meets or exceeds European CE requirements and
is fully commercially rated. In all other respects, this
helmet is nearly identical to the Kirby Morgan 37.
The Kirby Morgan 57 helmet features our revolutionary new SuperFlow
®
450 Stainless Balanced
Regulator. It's machined from a stainless steel casting
for the ultimate in performance and reliability.
Like all KMDSI regulators on our helmets and
Band Masks, we use only regulators that are specifically designed for surface-supplied diving, that will
perform over the wide range of pressures delivered
by low pressure compressors. An ordinary SCUBA
regulator mounted on a diving helmet is not capable
of delivering the gas you need at heavy work loads.
This commercially rated fully diver adjustable regulator delivers all the breathing gas you might require
for the most demanding work underwater.
The Kirby Morgan 57 also includes our QuadValve™ Exhaust System. It's recommended for diving in biologically contaminated water, when you're
properly trained and equipped, using recommended
procedures. This new exhaust has exceptionally low
exhalation resistance that you must experience to
appreciate.

Every model of KMDSI helmets and masks undergo
extensive type testing to fully document the performance capability and required supply pressures when
using various umbilical and pressure combinations.
All users should take the time to become knowledgeable on supply requirements to insure proper performance and for the comfort and safety of the diver.
The required supply pressures for the SL-17 equipped
with the SuperFlow
®
350 regulators are listed in the
appropriate supply pressure tables in Appendix 3.
The supply pressures listed in the supply tables were
derived by breathing simulator trials. There are two
tables used for the SuperFlow

and SuperFlow® 350
regulators. It is important that users understand how
to use the tables. For further information on supply
requirements for the SL-17 or any Kirby Morgan

2.4 Regulator Performance
®
-17
The demand regulator and side
block assemblies have a maximum design pressure of 250
psig (17.2 bar) over the ambient pressure, higher pressures
could lead to component failure
resulting in serious injury.
The regulator on the SuperLite®-17B offers very good
performance. The helmet has been tested at Dive
Lab in Panama City, Florida, as well as by other the
United States Navy’s Experimental Diving Unit and
other independent testing laboratories.

The cage code for identifying KMDSI products for
U.S. government purchase purposes is 58366.
risk of decompression sickness. Omitted
decompression due to a loss of the breathing gas supply or other accidents can cause
serious injury or death. Use of a SL 17 cannot
prevent this type of injury.
It is important for the user/diver to take
excessive currents into consideration. The
Quad-Valve™ Exhaust PN#525-759 is now
standard on the SuperLite 17B. Unlike the
old latex double exhaust, the quad system
is not limited to a maximum depth of 150
FSW (46 msw) due to exhalation pressure.
-Temperature Limitations: Use at water temperatures
below 33°F (1°C) requires the use of hot water shroud
PN# 525-100 and hot water to help prevent icing of
the demand regulator.
SuperLite® 17B
The umbilical assembly should be composed of good
quality diving hose that meets industry standards.
Generally, gas hose will be married to the communications wire, pneumofathometer hose, and strength
member in a manner that will allow the strength
member to receive all the strain. There are also good
quality umbilicals available that are assembled at
the factory using a twisted method which does not
require marrying.
Regardless of the system used, the umbilical is the
diver’s life line and should always be of excellent
quality and maintained carefully.
Gas systems used to supply Kirby Morgan
helmets and masks must be capable of supplying gas to the diver at the required pressure and ow rates as stated in the operational specications. The use of unregulated
gas sources is extremely dangerous.
NOTE The Hot Water Shroud (Part #525-100) in
conjunction with hot water to the diver should be
used whenever diving operations are conducted
using HEO
at water temperatures less than 60°F
2
(15.56°C) for the comfort of the diver.
KMDSI further recommends that the shroud
be used in conjunction with hot water to the diver
whenever diving operations are conducted using air
or mixed gas, in waters colder than 33°F (1°C) to
reduce the possibility of demand regulator icing.
NOTE: Usually the greatest danger of demand
regulator icing will be encountered on deck when
the surrounding air temperature is less than 32°F
(0°C). This effect is primarily due to the refrigeration effect of breathing air pressure reduction, and
the addition of moisture from the divers exhalation
coming in contact with the topside air temperature.
If diving where the water temperature is 33°F
(1°C) or warmer but the topside air temperature is
below freezing, (32°F (0°C) icing of the demand
regulator is possible. To help eliminate the possibility of freezing on the surface, warm water should be
run over the exterior of the demand regulator prior
to water entry, if the hot water system is not used.
Only equipment certified and tested according to EN
250/E DIN 58 642 may be used with the SL 17 helmet
when conducting diving operations in European EC
compliant countries.
The use of standard SCUBA type regulators
is unacceptable, as there are no provisions
for adjusting the intermediate pressure to
the diver. Only proven systems that allow for
varying the gas supply pressure to the diver
should be used for umbilical diving.
2.7 Helmet Features
All Kirby Morgan diving helmets are manufactured
by hand. Each step of the manufacturing process is
carefully controlled to assure the customer a high
quality, durable helmet that will function properly.
The SL 17 was developed in the late 1970s and it is
still one of the most popular diving helmets in the
world, a tribute to its timeless design.
The SL 17 incorporates an innovative locking system
and the SuperFlow
which provides an outstanding breathing gas flow
during peak work output.
The helmet consists of two pieces: the helmet shell/
helmet ring and the neck dam/yoke assembly. The
head cushion and yoke gives the diver a secure fit
in the helmet. The fit and balance seats the helmet
comfortably for long periods of time even when
working in the face down position.
The SL 17 is configured to receive the umbilical over
the shoulder.
In the past, the optional Double Exhaust System (Part
# 525-102) was available to reduce the possibility of
back flow of water and contaminants into the helmet.
This system has been used successfully for diving in
biologically contaminated environments for many
years. To further reduce the possibility of water intrusion regardless of the exhaust system being used, the
diver should avoid working in an inverted position.
The double exhaust was replaced by the QuadValve™ System. The unique design of the QuadValve™ helps keep exhalation resistance low while
maintaining excellent watertight integrity.
Before attempting any diving in any type
of contaminated water, a complete diving
and topside course in hazardous materials emergencies should be completed.
The divers and the topside team must
be properly trained and have the proper
safety equipment. All helmets and suits
can leak water under certain conditions.
Divers should use extreme caution when
diving in contaminated waters. For more
information see the book “Diving in HighRisk Environments” by Steven M. Barsky.
lowing is a general description of the features of the
SL 17.
When diving in heavy current (i.e. exceeding 3 knots) the single exhaust system
on all KMDSI masks/helmets could allow
water to enter, due to turbulence/eddying. It is important for the user/diver to
take excessive currents into consideration. The Quad-Valve™ Exhaust system
will help prevent water intrusion when
diving in heavy currents. Unlike the old
double exhaust, the Quad-Valve™ does
not limit the diving depth.
The Quad-Valve™ exhaust system is now standard
equipment for the SL 17. This superior exhaust system has exceptionally low exhalation resistance, and
helps to keep the helmet free of contaminants in polluted water. The Quad-Valve™ isolates the breathing
system from the surrounding water with a four valve,
low breathing resistance design (Patents Pending).
The Quad-Valve™ is designed to couple the regulator
exhaust with the helmet main exhaust and route them
into a single plenum chamber, mounted between the
regulator body and main exhaust body. The exhaust
gas then must pass through either one of two (or both)
exhaust valves that are part of the bubble deflector
(whisker wing). By having an exhaust valve in both
sides of the bubble deflector, exhalation resistance is
minimized, while still helping to maintain the isolation of the main helmet and regulator exhaust valves.
1) The fiberglass shell face port (or view port) area
remains unchanged. The side block and bent tube
assembly that transports air/gas to the demand regulator from the side block are also the same. Most of
the components in these areas are interchangeable
between the 17B and models 27, 37, 47, and 57.
2) The neck dam on the SL 17 is secured by the neck
clamp. Replacement neck dams install easily.
3) The head cushion attaches just inside the bottom
of the helmet, keeping it in place when the diver
dons the hat. The standard head cushion consists
of a brushed nylon bag with an open cel polyester
foam inside. Only genuine Kirby Morgan SL 17 head
cushions should be used to ensure proper operation
and comfort.
4) The handle that is fitted to the top of the SL 17 and
the port weight are areas that can be used as mounting
brackets for lights, TV cameras, etc.
2.8 General Description
2.8.1 Helmet Shell
The helmet shell is fabricated of noncorrosive, rigid
fiberglass which will not carry an electrical charge.
This shell is the central structure for mounting all the
components that make up the complete helmet. It is
designed to allow easy replacement of parts when
necessary. Any repair to the helmet shell must be
done at an approved KMDSI repair center.
Other helmet features which are common to all
KMDSI helmets include:
• the face port and retainer ring
• basic communications components
• the oral nasal mask
• the nose block device
• the air train
• most demand regulator components
Many of the breathing system components on these
helmets are also compatible with the KMB 18B and
28B. This helps reduce the inventory of spare parts
that must be carried by commercial diving companies.
Each step of the manufacturing process is carefully
controlled to assure the customer of a high quality,
durable helmet that will function properly. The fol-
The main gas supply flow from the umbilical enters
the system at the adapter and flows through the one
way valve to the interior of the side block. The one
way valve or “non-return” is a very important component.
It prevents the flow of gas out of the helmet to the
umbilical in the event of a sudden lowering of pressure in the supply hose. This can happen due to an
accidental break in the hose or a fitting near the
surface. Not only would the Auxiliary gas be lost if
the one way valve failed (concurrent with a hose or
fitting break on deck), but the diver could suffer from
a serious “squeeze” that could cause injury or death.
Although we have selected the valve for its reliability and quality, inspection and maintenance of
this valve must be done regularly. It is very easy to
disassemble and inspect. (A rebuild kit for this valve
is Part #525-330).
Gas Flow To Air Train
Main Gas Supply
Gas Flow To Regulator
Auxiliary L.P. Port
The one way valve must be tested daily, prior
to the commencement of diving operations.
Failure of one way valve could cause serious
injury or death. Follow the procedures for
testing the valve in this manual.
The emergency gas comes from a tank of compressed
gas worn by the diver. It enters the system through
the Emergency Gas valve when the diver turns the
control knob on. The flow then enters the side block.
Returning to the side block assembly: the other passage for gas is to the demand regulator. It goes to a
bent tube assembly that connects to the inlet nipple of
the demand regulator. The flow of gas in the demand
regulator assembly is controlled by the inlet valve
that supplies gas to the diver on inhalation “demand”
only, and shuts off during the exhalation cycle.
The SuperFlow
®
demand regulator senses the start
of the divers inhalation and opens the inlet valve,
matching the diver’s need. The regulator continues
to match the diver’s inhalation as the rate increases,
peaks, then ebbs and stops.
When the diver exhales, the supply gas stays off
as the exhalation gas flows through the regulator
body, out the regulator exhaust valve, through the
Quad-Valve™ whiskers, and out into the water. The
whiskers deflect the exhaust bubbles away from the
face port to keep the diver’s view clear.
All KMDSI Helmets and Band Masks are equipped
with a multi-turn demand regulator adjustment knob.
This adjustment knob allows the diver to make corrections to compensate for a wide range of incoming
gas supply pressures. See the section in this chapter
regarding appropriate supply pressures.
Both sources of gas flow through the same passage in
the side block body to two exits. One exit is always
open to supply gas to the demand regulator assembly.
The other exit is to the defogger valve (free-flow
valve) assembly.
The diver controls the flow of gas through the defogger system with the control knob. The gas enters the
helmet and flows through the air train which directs
the gas onto the face port to help eliminate or clear
fogging of the faceplate that forms from the diver’s
warm breath.
The flow continues out through the water dump (helmet exhaust) valve, or into the oral nasal by means of
the valve, then into the regulator and out through the
regulator exhaust to the Quad-Valve™ whiskers. The
diver can breathe from this flow of gas if the demand
regulator malfunctions.
Never connect the main gas supply hose
from the diving station/umbilical to the emergency valve. There is no one way valve in
the emergency valve. If this mistake is made,
any break in the supply hose could possibly
result in a “squeeze”.
This could result in serious injury or death.
The adjustment knob operates by simply increasing
or decreasing the amount of spring bias tension on the
demand regulator inlet valve. The adjustment knob
has a range of approximately 13 turns from full in
to full out. The intent of this bias adjustment device
is strictly to allow the diver to make adjustments for
variations in umbilical supply pressure.
This adjustment device is not intended as a minimummaximum device. Minimum and maximum applies
to supply pressure only. The adjustment knob should
be adjusted by the diver to be at the easiest breathing setting at all times. The exact number of turns
required is dependent on the supply pressure.
The regulator adjustment knob should be
adjusted to the easiest breathing setting
at all times. Adjusting the regulator further in than necessary to keep from freeowing increases breathing resistance.
The side block on the helmet is drilled and tapped
to accept low-pressure inflator hoses. This allows
the diver the capability to inflate variable volume
dry suits. It is tapped with a 3/8-24 thread orifice,
standard for American first stage scuba regulator’s
low-pressure auxiliary fittings.
The port is shipped plugged at delivery. This inflation
capability does not significantly interfere in any way
with the breathing characteristics of the regulator
during normal use providing a limiting hose is used.
When using a dry suit inflation hose, the hose should
be equipped with a flow restrictor (P/N 555-210) to
limit flow in the event the hose ruptures or is severed.
Diving a KMDSI helmet or BandMask
®
with a bias
setting greater than that just necessary to keep the
demand valve from free flowing increases the work
of breathing and reduces the diver’s ability to perform
heavy work.
The side block inator port is intended
for dry suits only. When using the side
block low-pressure inflator port, only
good quality hoses and ttings should be
used and must incorporate an in-line ow
restrictor to reduce gas ow in the event
of hose failure. Any hose or tting failure
in this arrangement will subject the diver
to a decreased air supply. Do not use the
side block inator port for any purpose
other than attaching a dry suit hose.
Alignment
Sleeve
SuperLite® 17B
The KMDSI Restrictor Adaptor,
KMDSI Part #555-210.
When using the side block low pressure
inator port, the diver should only use
high quality hoses with an integrated ow
restrictor or a KMDSI ow restrictor PN#
555-210. All hoses must have an in-line
restrictor to reduce the gas ow in the
event of hose failure.
Do not use tting adapters. Standard
adapters do not provide an adequate
ow restriction. The use of many off the
shelf adapters on the side block assembly could expose the low pressure hose
ttings to excessive stress. Any failure of
an ination hose will subject the diver to
a decreased supply pressure.
2.8.3 Emergency Gas Supply System (EGS)
KMDSI strongly recommends that the working diver
carry an independent supply of compressed gas (or
air) fitted with a first stage regulator and hose that is
connected to the inlet of the Emergency Gas Valve
(EGV).
The KMDSI Overpressure Relief Valve, (part number 200-017) is fully adjustable and rebuildable and
has been designed to relieve any over-pressurization
of the first stage regulator greater than the desired
setting.
Every bailout (Emergency Gas System or EGS) first
stage regulator must be fitted with an overpressure
relief valve to prevent over pressurization of EGS L.P
hose and possible total loss of emergency supply gas
in event of regulator failure.
The over-pressure relief valve should
be installed on every first stage used
for bailout.
KMDSI Part #200-017
NOTE: This valve can be adjusted for various relief pressures.
2.8.4 Helmet Attachment to the Diver
On the SuperLite
®
-17 A/B, the helmet shell has an
O-ring seal around the base of the fiberglass rim. The
helmet is held in place on the diver’s head by the
yoke/neck clamp, which mounts on the diver’s neck
and seals to the bottom rim of the helmet.
The adjustment of this clamp is critical to the safe
use of the helmet. Periodic adjustments to the clamp
MUST be made as the neck dam ages or if you
convert to a dry suit mount. The adjustment should
always be checked if the yoke clamp assembly is
used on different helmets. YOU SHOULD NEVER
HAVE TO FORCE THE CLAMP SHUT.
Do not dive unless the latch catch is properly engaged and the strap guide and yoke
strap are in position. Failure to use these
devices to properly secure the helmet on
the diver’s head could lead to drowning,
which may result in severe personal injury
or death.
The head cushion is made from layers of open cell
foam inserted in a head shaped nylon bag. Adding

be adjusted correctly for the helmet to fit properly.
gas supply hose. A leaky rst stage can
overpressure the hose resulting in hose
rupture. This would cause a loss of the
entire emergency gas supply, with possible serious injury or death.
2.8.5 Sealing Arrangement
The neck dam is available in several sizes and is
fabricated in a cone shape. The neck dams on all
SuperLite
®
-17A/Bs are made of foam neoprene.
The neck dam seals against the diver’s neck. The fit
of the neoprene neck dam may be made larger by
trimming 1/4” off the circumference. Only trim a
maximum of 1/4” at a time; trimming too much will
result in a loose fit.
NOTE: If you must trim the neck dam, be careful not to trim off too much material. The neck
dam must t snugly. While it may be a slight
bit uncomfortable out of the water, and may
feel snug, once in the water the neck dam will
loosen slightly.
Pulling the neck dam over the diver’s head
can be difcult. Stretching (expanding) the
seal and placing it part way over the head
can help reduce the force needed to install
the seal. Proper training is necessary to install the neck seal over the diver’s head and
onto their neck. Although the possibility is
very remote, injury may result if this procedure is not done properly. If a diver does not
know how to don the neck dam, they must
seek proper instruction before proceeding.
2.8.6 Reducing Carbon Dioxide
It is important to minimize the volume of air/gas
space that the diver is breathing through. Carbon
dioxide (CO2) can build up if proper flushing does
not occur. A silicone oral nasal mask is located inside
the helmet that fits over the diver’s nose and mouth.
The oral nasal mask, valve, and equalizing device.
The oral nasal attaches to the regulator mount nut.
This separates the breathing gas flow from the rest
of the dead-air space inside the helmet, subsequently
reducing the potential for carbon dioxide buildup.
Always be sure the oral nasal valve is properly mounted in the oral nasal mask. If the
valve is mounted improperly or is absent
this can lead to a higher CO

dizziness, nausea, headaches, shortness
of breath, or blackout.
2.8.7 Communications
In the SL 17, both earphones and microphone are
wired in parallel to the communications system.
The communications can be equipped with either a
waterproof connector, or binding posts for bare wire
connection.
Electrical signals are sent to, and received from, the
surface through the umbilical wires. An amplifier
boosts the signals to the desired volume for the surface and the diver.
2.8.8 Equalizing the Middle Ear
A nose block device allows the diver to block their
nose to provide an overpressure in their middle ear
for equalization. The blocking pad on the inside of
the oral nasal mask is attached to a shaft which passes
through a packing gland to the outside of the helmet.

The yoke and latch catch assembly must work properly
A knob attached to the end of the shaft can be pushed
in to slide the pad under the diver’s nose.
When not needed, the knob is pulled out so the pad
does not rub under the diver’s nose. The pad may also
be turned upside down (to provide more clearance
under the diver’s nose) by rotating the shaft.
2.8.9 Face Port or Viewing Lens
The face port or viewing lens is extremely strong clear
polycarbonate plastic which is easily removable for
replacement of the lens. An O-ring, located under
the lens, seals the lens to the fiberglass helmet shell.
The port retainer screws must be tightened
to proper torque specications per the instructions in this manual. See Appendix 1
for proper torque specications. Do not over
tighten. This could lead to helmet ooding
and drowning could result.
The Latch Catch is designed so that in the event that
the pin is pulled and the yoke drops down, the neck
clamp will remain closed. It’s like two separate locks.
Old latch catch assembly. This device should not be used any
longer.
2.8.10 Latch Catch Assembly, Pull Pin
The latch catch assembly includes the pull pin and
safety pin. The purpose of this assembly is to ensure
that the neck clamp assembly remains securely fastened around the base of the helmet, so the helmet
remains on the diver. This arrangement functions in
a similar manner to the old “dummy pin” on a heavy
gear helmet.

allow the bag to breathe. The bag is also equipped
with large carrying straps and side pockets. The bag
is not intended for shipping your helmet as air cargo.
The part number for the bag is Part #500-901.
2.11 Use of Kirby Morgan Original
Replacement Parts
Users of Kirby Morgan life support equipment are
cautioned to always use Kirby Morgan original replacement parts. Parts manufactured by third party
companies can cause accidents.
This manual is our effort to explain the operation, maintenance and use of the SuperLite®-17B.
We do not herein make any effort to teach the principles of diving. It is our assumption the reader
is a qualied diver. We highly recommend that all divers should train, under controlled conditions, in the use of any model of commercial diving helmet that they have not previously used or
trained in, prior to use on the job.

Kirby Morgan diving helmets are not intended for use with a self contained gas
supply (scuba). There is no provision for
surface swimming once the scuba air
supply is depleted. This could lead to
suffocation or drowning, which could be
fatal.
However, divers that are familiar and trained in the
use of previous Kirby Morgan masks; i.e., KMB 8,
9, 10, 18, 28, the Navy MK. 1 mask, Navy MK. 21
helmet, or the Navy Mk. 22 mask, or other Kirby
Morgan helmets, will find that all Kirby Morgan
diving helmets and masks have the breathing system
controls located in the same position. The operation
of this helmet will also be similar. The diver must be
tended at the surface at all times by a trained, qualified commercial diving tender.
3.2 Design Purpose
All Kirby Morgan diving helmets are designed for
use with an umbilical.
The umbilical is usually composed of at least a gas
or air supply hose and communication wire, assembled with waterproof tape (and in some umbilicals
wound similar to strands in a rope) to form a single
unit. Some umbilicals also have included a hose for
hot water, a pneumofathometer hose, and a strength
member, such as a cable or strong line.
It is strongly recommended that the air/gas umbilical
be married to a strength member in a manner that
allows the strength member to receive the strain.
This will help reduce the possibility of umbilical and
umbilical fitting fatigue and possible failure.
The diver must be tended at the surface at all times
by a trained, qualified commercial diving tender.
SuperLite® 17B
WARNING
WARNING
The umbilical is the diver’s lifeline to the diving
control station.
The diver must be tended at the surface at all times
by a trained, qualified commercial diving tender.
Never dive without a qualified tender holding your
diving hose.
The diving control station can be at the surface, in
a diving bell, or in a submerged habitat. The diving
control station is the center of the air/gas supply, communications with the diver, and diving procedures.
The station can be as simple as a tender with a set of
“phones” (communication amplifier), or as complex
as a control van in the midst of a saturation system.
Decompression diving always involves
the risk of decompression sickness.
Omitted decompression due to loss of
gas supply or other accidents can cause
serious injury or death. The use of the KM
37 or 57 cannot prevent this type of injury.
When using a high-pressure console, for maximum
breathing performance it is desirable to maintain an
over bottom supply pressure of 150-165 p.s.i.g. (10.2
bar) when diving to depths of 100 FSW (30 msw),
and 175-200 p.s.i.g. (11.2-13.6 bar) over bottom
when diving to depths in excess of 100 FSW (30
msw). With the many different gas supply console
configurations in use, it is important to ensure that
the gas supply system used, is capable of supplying
the helmet with the necessary pressure and flow of
gas to allow the diver to work safely and efficiently.
See Table 1 in Section 2.5 as a guide to supply pressure requirements.
When using a low-pressure compressor (200-225
p.s.i.) follow the recommendations in Table 2 in Section 2.5 for optimum performance.
In countries that have adopted C.E. standards only
C.E. certified supply systems and components may
be used in conjunction with the helmet.
KMDSI manufactures a complete Air Control System,
the KMACS 5™ with or without integrated communications as well as pneumofathometer. This portable
system can be operated on either a high pressure air
supply or on a low pressure compressor. The Air
Control System has a specially designed high pressure
regulator that reduces high pressure air and provides
an adequate flow to support divers to a depth of 130
FSW (40 msw)
The helmet demand regulator and side block assemblies have been designed to operate with a supply pressure from 90 p.s.i.g. (6.2 bar) over ambient pressure to
225 p.s.i.g. (16 bar) over ambient pressure. This wide
operating range allows flexibility when using various
gas supply systems.
High pressure supply regulators and associated piping systems for surface supplied diving with Kirby Morgan helmets
and masks must be capable of delivering
a minimum of 4.5 acfm to the diver at
depth. Only systems that can deliver the
required gas ow should be used.
When you first receive your Kirby Morgan diving
helmet, carefully unpack it and examine it for any
damage that may have occurred during shipment.
Use the inspection sheet provided to ensure that no
damage has occurred. The purchaser must contact the
freight carrier and/or the KMDSI dealer if the helmet
has been damaged in shipment.
Be sure to complete the enclosed warranty card
and return it to KMDSI immediately. No warranty
claims will be honored without a correctly completed
warranty card on file at KMDSI.
KMDSI must have your current address
to ensure that you receive all safety notices and other important information
concerning the helmet. Please notify
KMDSI of any change of address.
3.4 Initial Adjustments to Your
Helmet
Before using the helmet for the first time, it must be
checked and adjusted for proper fit. There are several
adjustments that must be made to provide a more
comfortable fit when wearing the helmet.
3.4.1 Head Cushion
The fit of the helmet is primarily determined by the
layers of open cell foam that fill the head cushion bag.
The center top/rear foam in the SuperLite
very dense to reduce compression and spring-back.
This reduces the tendency of the helmet to ride up
when underwater. Do not replace this rigid foam with
a soft foam. A softer foam is used on the sides and
around the bottom of the head cushion.

remove foam to adjust the fit.
with scissors to provide a better fit, or more foam can
be added to give a tighter fit.
The head cushion fit is extremely important. A proper
fitting headliner keeps the nose and mouth securely
in the oral nasal allowing a good seal and providing
maximum regulator performance and CO2 washout.
On the SuperLite
from the head cushion bag. The chin strap bolts directly to the helmet and is secured around the outside
of the head cushion in the chin area. Ensure the chin
strap is used.
If the chin strap is not fastened or positioned properly,
the helmet can float up on the diver’s head. This can
make the helmet very uncomfortable and may pull
®
-17B there is a chin strap separate
The diver’s head can be moved forward into the oral
nasal mask by adding layers of additional foam at
the rear of the head cushion. The diver’s head can
be moved up or down in the helmet by decreasing
or increasing the foam pads at the top of the head
cushion.
Usually, a diver with a small head will use all the foam
that comes with a new hat. A diver with a larger head
will need to remove a layer of foam in the center top
and back of the head cushion. The foam may be cut
On older SuperLite®-17B helmets the chin
strap is part of the head cushion. All helmets should be changed to have the chin
strap bolt directly to the helmet.
Old style head cushions with chinstraps
may be used, but the chin strap that is
bolted to the helmet MUST be used. We
recommend that the old head cushion
chin strap be removed (i.e., cut off) to
prevent confusion.

the oral nasal mask away from the face. Additionally, in the unlikely event the helmet was separated
from the neck clamp/yoke assembly, the helmet will
be retained.
3.4.2 Adjusting the Neck Dam
If your helmet is new, or any time you replace the
neck dam, it must be adjusted to fit you. New neck
dams are cone shaped and will probably be too tight
if not properly trimmed.
Trim the neck dam until it is still snug. (You can
Never dive with a neck dam that is too
tight. A neck dam that is too tight could
cause the diver to pass out due to pressure on the carotid artery in the neck.
This could lead to severe personal injury
or death.
also stretch it by sliding it over a SCUBA tank and
allowing it to sit overnight.) If you still cannot get
the proper fit by stretching the neck dam, it must be
trimmed further. Do not trim more than 1/4 inch at
a time.
Avoid trimming neoprene neck dams too
much. Neoprene neck dams will loosen
over time as they are used and the cells
of the foam neoprene break down. If you
trim the neck dam too much it will be too
loose and will leak. Trim the neck dam
until it is snug, then stretch it before use.
Do not breathe the
fumes from uncured
neoprene cement.
These fumes are
dangerous and can
cause unconsciousness. They can also
cause long term
damage to body
tissue. Read and
follow all precautions listed on the neoprene cement can. Allow neoprene cement to cure for a minimum of 24 hours
before using the helmet.
Trim the neck dam until it is still snug. Trim only a
maximum of 1/4 inch off the circumference of the
neck dam at a time. When you are done, the neck
dam must be tight enough so that it does not leak.
This may feel a bit snug out of the water, but will
be more comfortable underwater once the neoprene
compresses from increased pressure.
Trim the neck dam with the largest, sharpest scissors
available, in order to make as few cuts as possible.
There must be no jagged edges on the neck dam or it
may eventually tear. Sew and/or glue the edge of the
original seam to keep the stitching from unraveling.
As the neoprene neck dam ages, it will become looser,
due to a natural breakdown of the cells. This is particularly true if the helmet is locked in and out of a
bell or saturation system. As the neck dam becomes
worn it will need replacement to ensure that it seals
properly.
A neoprene neck dam that is too large may be tightened up by cutting a wedge out of the open end. Glue
the cut back edges back together using wet suit cement, then sew the glued seam together. Be sure to
New neck dams must be adjusted so that they fit
properly.
allow the modification to the neck dam 24 hours to
dry and solvents to off gas.
Before dressing in for a dive, inspection of the helmet
systems must be made to be sure it is in proper working order. This must be done well in advance of the
dive so any problems can be fixed without delaying
the dive. The following steps are part of the recommended daily maintenance.
SuperLite® 17B
Binder head screws are used in this application for
their self locking characteristics. Overtightening may
strip out the threaded inserts in the helmet shell.
3.5.1 Pre-Dive Visual Inspection
Visually inspect the exterior and interior of the helmet.
1) The demand regulator cover assembly should not
have excessive dents or dents deeper than 1/4”. The
purge button must operate freely and should have no
less than 1/16” and no more than 1/8” inward travel
before gas flow is heard.
There must be no holes in the neck dam.
If there are any holes in the neck dam the
helmet could leak or ood. In addition,
the demand regulator will not operate
properly. Drowning could result.
2) The neck dam must not be torn or punctured, and
properly trimmed to fit.
3) Inspect the O-ring on the bottom of the helmet
shell. The O-ring must be in place and undamaged.
4) Inspect the bent tube that supplies breathing gas
to the regulator. There must be no dents or kinks in
the assembly, or visible signs of damage.
5) Inspect the face port. It must be in good condition.
The O-ring on the base of the helmet
shell on the SuperLite
place and in good condition. Without a
proper functioning O-ring the helmet will
leak and possibly ood. Drowning could
result.
10) Make sure the head cushion is properly fastened
(snapped) inside the helmet to the snap tabs.
11) Make sure the chin strap is the new version that
bolts directly inside the helmet with tab bolts. If the
older system is used where the chin strap is part of
the head cushion, replace it as soon as possible.
12) Make sure the strap guide and yoke strap that help
secure the helmet are in place and in good condition.
All parts on Kirby Morgan diving helmets
must be adjusted to their proper torque
specifications. See Appendix 1 for a
complete listing of torque specications
for each part. Failure to adjust parts to
the recommended specications could
lead to helmet failure and accidents. This
could be fatal.

6) Be sure the communications wires are hooked up
and tested.
7) Inspect the oral nasal mask. Make sure it is on
the regulator mount nut properly and the valve is
installed properly.
8) Make sure the head cushion is properly fastened
inside the helmet.
9) Check the screws on the port retainer . They must
be adjusted to the proper torque setting specifications
noted in Appendix 1 of this manual.
Thoroughly clean the face port with a soft cloth and
a mild liquid detergent solution. DO NOT USE ANY
AEROSOL SPRAYS ON THE POLYCARBONATE
PORT!
3.6.2 Check Moving Parts
Check all moving parts, such as the regulator adjustment knob, the defogger control knob, emergency
(EGS) knob, and the nose block device knob and the
yoke/neck clamp parts to ensure smooth and proper
operation.
Inspect the yoke/neck clamp and latch catch mechanism. They must engage and disengage properly. If
the Yoke/Neck Clamp Assembly has been used with
a different helmet, it MUST be readjusted to fit the
current helmet.
3.6.3 Check Communications
Check the communications system for proper operation. Put the helmet on and talk to an assistant on the
amplifier. If you are by yourself, with the helmet off
take the helmet near the amplifier and tap on each
earphone and the microphone, listening to the taps
on the amplifier/speaker.
Talk into the amplifier/speaker feeling the vibration
on each earphone and the microphone with your
fingertips. Check the fit and tightness of the comm
module mount nut.
3.6.4 One-Way Valve Check
The one-way valve must be tested daily, prior to
commencement of diving operations. There are two
ways to test the valve
1) Prior to attaching (or pressuring up) the umbilical,
close the emergency valve knob, attach and pressure
up the emergency hose. Shut off the defogger control
knob and screw in the adjustment knob on the regulator all the way.
2) With the emergency hose pressurized, turn on the
emergency valve knob. If any gas escapes out the end
of the adapter, the one-way valve is faulty and must
be rebuilt or replaced. A one-way valve repair kit is
available for rebuilding these valves (Part # 525-330).
You can test the one-way valve either by attempting
to suck air through the valve with the steady-flow
valve open, or by connecting the bail-out to the main
supply (with the steady flow and regulator adjustment
closed) and opening the emergency valve to check
for back-flow.
3) You can also test the one-way valve by opening
the steady-flow valve and attempting to suck air
back through the one-way valve. This is also a
good way to test.
Never dive if the one-way valve is not operating properly. If the hose or breathing
gas/air tting breaks near the surface a
serious injury could result to the diver’s
lungs and/or eyes. In extreme cases this
could be fatal. The one-way valve must
be tested daily prior to the commencement of diving operations. Failure of the
one-way valve could cause serious injury
or death.
If the diver’s main gas supply fails, the diver must
have another source of gas that will enable them to
return to the dive station or to a point where a normal gas supply can be reestablished. For this reason,
an emergency gas supply (bailout) cylinder must be
used on all dives. The bailout cylinder is normally
worn on the back using a combination backpack and
lifting harness.
Do not dive without a diver worn Emergency Gas System. If the main gas supply
is lost, you will have nothing to breathe
and may drown.
lower rear or front, while larger tanks are usually
mounted vertically in the center back similar to a
Scuba diver’s tank. Some harness designs incorporate
a cloth enclosure into which the tank fits. The entire
tank, valve, and regulator are enclosed in fabric. This
helps to prevent snagging.
Never dive without attaching the umbilical to some type of harness or clip on the
diver’s body. Never allow the umbilical to
pull on the helmet directly or the diver
could suffer a neck injury.
The diving harness
must have a provi-
sion for attaching the
emergency gas supply
and a place to attach
the diver’s umbili-
cal.
Diver donning a complete bail-out system.
Most commercial divers wear a harness (separate
from the weight belt) that is used for several purposes.
The harness is fitted with large metal rings (usually
brass or stainless steel).
The umbilical is hooked into one of these rings
to keep any strain off the helmet. In addition, the
rings on the harness are used to hang tools and other
equipment. Usually the harness is also designed to
provide a means of lifting an unconscious diver from
the water. This harness is the best method of securing
the emergency breathing gas to the diver.
The umbilical should always be attached to the harness to avoid a direct pull on the diver’s helmet.
SuperLite® 17B
WARNING
WARNING
When determining the size of the emergency gas
cylinder to use, several factors must be considered.
The divers depth, the length of time the diver may be
without the main gas supply, and the gas consumption rate. Regardless of the cylinder used, it should
be of sufficient volume to allow the diver to ascend
at a normal rate or transit to a point where a normal
gas supply can be reestablished.
A standard SCUBA submersible pressure
gauge must be connected to the high
pressure port on the rst stage so that
the diver can monitor their emergency
supply.
Use a good quality first stage for
your emergency gas supply.
European C.E. ONLY
In European countries that have adopted C.E. certification, only C.E. certified cylinders are allowed to
be used and must have a minimum charged capacity

diver pressure. The KMDSI SuperFlow
®
First Stage
SCUBA regulator (Part #305-161) is an excellent
device for this use.
These regulators reduce the tank pressure to approximately 145 p.s.i.g. (9.9 bar). Other quality high
performance Scuba regulators may also be used.
Connect the first stage hose with a set of quick disconnecting locking sleeves to the emergency valve
assembly located on the side block.
An over-pressure relief valve
must be installed on the first
stage used for the Emergency
Gas Supply.
The first stage regulator must have at least two low
pressure ports. One port is used for the connector
hose to the emergency valve and the second is used
to install an overpressure relief valve (Part #200-017).
If the first stage develops a leak, the full pressure of
the tank could be placed on the low pressure hose.
This could cause the hose to burst. The overpressure
relief valve will bleed off any leak.
Make sure the emergency valve knob is turned off,
otherwise the emergency gas supply will be used up
without the diver’s knowledge. Once the emergency
supply hose is connected, the tank valve is turned on
to pressurize the hose. In the event of an emergency
due to a loss of the main gas supply, the emergency
valve knob located on the side block is turned on
supplying gas to the side block assembly and the
regulator.
The relief must be adjusted to start lifting at approximately 20 p.s.i.g. (1.4 bar) above the regulator
intermediate setting. The purpose of the relief valve
is to allow pressure to vent off in the event the first
stage regulator develops a leak or creeps. Without a
pressure relief valve, the hose could rupture and the
emergency gas supply would be lost.
The emergency air/gas tank must be fitted with
a good quality first stage regulator to reduce the
Never dive without an over pressurization
relief valve installed on the EGS regulator
(1st stage). Without the relief valve if the
EGS regulator develops an internal leak, or
carries-away, the full pressure of the EGS
cylinder would be placed on the low-pressure EGS hose and the Emergency Valve.
This could cause the low-pressure hose to
burst resulting in the complete loss of the
EGS system.
There are several possible ways to configure your emergency gas system, although at KMDSI we only recommend one method. The configuration we recommend is as follows:
Cylinder Valve Open - EGS Valve on Helmet Closed
This is the only method that we recommend. The advantages of this method are as follows:
• You only need to open one valve to activate your emergency supply.
• There is little danger of flooding your first stage regulator and ruining it.
Possible Emergency Gas Supply Cylinder & EGS Valve Configurations
Configuration 1 On Off Advantages
(Regulator pressurized) • One valve to open
• First stage won’t normally flood
Disadvantages
• If hose or first stage leaks some
or all EGS gas will be lost
Configuration 2* Off On Advantages
(No pressure in • One valve to open
regulator) • No loss of gas from cylinder
if hose leaks or regulator leaks
Disadvantages
• First stage will flood and must
be serviced after each day of
diving
Configuration 3* On momentarily Off Advantages
(Regulator pressurized then Off • No loss of cylinder gas if
then cylinder valve hose or regulator leaks
closed) Disadvantages
• Two valves to open in
emergency
• Slow leak on long dive may
result in flooded 1st stage
• If dive depth exceeds pressure
in first stage, first stage will flood
Configuration 4* Off Off Advantages
• No use of cylinder gas unless
emergency occurs
Disadvantages
• Regulator will flood and need
service daily
• Two valves to open in
* Requires ability to reach cylinder emergency
valve without difficulty
There are risks with each method of configuring your
bail-out system. There is a risk that if you have the
bail-out bottle on and the emergency valve on the
helmet closed, that the emergency gas could be lost
if the hose or the first stage itself develops a leak.
However, KMDSI believes that this method poses
the least amount of risk for the diver.
Probably the most serious problem with any of the
other possible configurations is that the first stage will
almost certainly flood if it is not pressurized while
you are underwater.
If the regulator floods and is not promptly serviced,
it will not perform properly when you need it in an
emergency. As a diver, you always must decide how
much risk and what types of risk you are willing to
expose yourself to when you dive. It’s up to each individual to make an informed choice regarding how
to configure your bail-out system.
Some divers, keep the EGS gas cylinder
valve shut during the dive. Their rationale
being; in the event of an emergency, they
will simply open the EGS cylinder valve
thus eliminating any EGS air/gas unknowingly being lost due to either a 1st stage
failure or EGS hose failure.
KMDSI strongly recommends never diving with the EGS cylinder valve shut. The
reasoning behind this is twofold. First,
with the EGS cylinder valve open, gas
is immediately available in the event of
topside gas interruption via the EGS valve
on the side block simply by opening it.
Secondly, and most importantly, if the
EGS regulator (1st stage) is not pressurized, during descent it is possible that sea
water will leak through the rst stage intermediate circuit and regulator, causing
failure of the EGS regulator and resulting
in possible injury or death.
Always be sure to check the pressure in your bail-out
bottle before you dive.
KMDSI strongly recommends the use of a submersible pressure gauge with every bail-out system. Not
only does this make it very easy to check your emergency gas pressure prior to diving, it also allows you,
in most cases, to periodically check the pressure in
your system while you dive. In this way, if you have
a leak, you will probably figure it out and will be able
to take appropriate action.
Never connect the main gas supply hose
from the diving control station to the
Emergency Gas valve assembly (EGS).
If this is done there is no one-way valve
protection for the diver in the event of
damage to the umbilical or related equipment. The diver could be exposed to a
serious “squeeze”. This can result in serious personal injury or death.
Never connect a high-pressure hose
directly to the EGS valve assembly, as
this will transmit the full pressure of the
tank to the side block. The side block is
not designed for high pressure and may
burst. This may result in severe personal
injury or death.
Before connecting the umbilical to the helmet, the
umbilical must be flushed out to remove any dirt,
moisture, or other debris. Connect the topside umbilical end to the topside diver control console. Ensure
there is no pressure in the divers umbilical.
Carefully uncap the helmet end of the umbilical and
hold securely while pointing in a safe direction, then
slowly bring up gas pressure to approximately 25-40
p.s.i.g. (1.7-2.7 bar). Allow the gas to flow for at least
15 seconds. If it is not going to be used immediately,
the umbilical should be recapped.
3.8.2 Connecting the Umbilical to the
Helmet
When you connect the hose to the helmet be sure to
use a wrench to hold the adapter, or inlet fitting, and
a second wrench to turn the swivel fitting on the hose.
If this is not done, the adapter will turn inside the oneway valve. If this happens repeatedly the threads will
wear and the valve will need to be replaced.
SuperLite® 17B
Connecting the umbilical to the helmet.
The connection between the hose and the helmet must
only be made up “snug”. Excessive force will deform
and ruin the adapter. A second wrench must be used
when the helmet is disconnected as well, otherwise
the adapter and/or the one-way valve assembly may
become loose and fail to make a seal.
If you are using waterproof connectors for your com-

munications, take extra care in handling these pieces.
To connect the male and female parts, align the large
pin on the male connector with the yellow mark on
the female connector. Press the two connectors together until you hear a distinct “pop”. Do not twist
the connectors. Tape the two connectors with a bit of
electrical tape to prevent them from pulling apart.
Always use two wrenches to connect the umbilical to
the adapter. Use the correct size wrenches whenever
possible to avoid damage to the fittings.
To separate the connectors remove the tape, grasp
them at the thickest part, place your thumbs against
each other, and push apart until the connectors are
disconnected.
Do not twist the connectors. Do not pull them apart
by pulling on the thin part of the wires.

WARNING
3.8.3 Opening the Breathing Gas Supply to
the Helmet
Prior to turning on the air supply for the helmet,
check to see that the free flow valve is closed and the
regulator adjustment knob is all the way in.
Slowly bring up the gas pressure to the helmet to 150
(10.2 bar). Slowly back out on the regulator adjustment
knob until a slight free flow develops, then turn the
adjustment knob in (clockwise) until the free flow
just stops.
To properly check the breathing system you must
completely don the helmet.
Never use any aerosol propelled sprays
near the face port of
the any Kirby Morgan
helmet or band mask.
The propellant used
in these aerosols can
invisibly damage the polycarbonate face
port and cause it to shatter upon impact
from any strong blow. If the face port
fails underwater the helmet will ood and
drowning may result.
Make sure that the regulator adjustment knob is
screwed in and the steady-flow valve is closed before
opening the air supply to the helmet.
3.8.4 Fogging Prevention
A thin film of anti-fogging solution may be applied
to the interior of the polycarbonate face port prior to
the dive to help prevent fogging during the dive. A
mild liquid dish washing soap, or other commercially
available anti-fogging solutions, may be applied with
a soft rag to the interior of the port.
The diver should use a solution which has been
found satisfactory in the past. However, do not use an aerosol spray on the polycarbonate lens. The
propellants in some aerosol dispensers cause damage
to the lens.
All donning procedures must be done by the diver
until they are thoroughly at home with the helmet.
This will train for familiarity. However, the tender
must be present to assist the diver and check to ensure
that the diver has properly donned their equipment.
It is impossible for the diver to see whether they are
properly dressed in once the helmet is on their head.
The tender must always be present to
assist the diver while dressing and whenever the diver has their helmet on their
head while they are out of the water. It is
difcult for the diver to walk while they
are dressed in and they can stumble and
fall, resulting in serious personal injury.
Pull the pull pin knob out, away from the helmet.
While holding the knob out, lift the neck clamp
handle up and out to release the tension on the clamp.
Swing the handle forward, toward the front of the
helmet. Slide the yoke/neck clamp assembly backwards away from the helmet until the rear hinge tab
disengages from the alignment sleeve.
As a diver, to don the yoke assembly, hold the yoke/
neck clamp in your hands in front of your body.
Swing the neck clamp assembly up towards your
chest. Lift the entire unit over your head until the
opening for the yoke is positioned at the back of your
neck. Slide the yoke forward until it is centered on
your neck.
Reach over your head and insert the four fingers of
each hand in the opening of the neck dam. Keep your
thumbs on the outside of the neck dam. Spread the
neck dam by pulling against the palms of each hand.
Pull the neck dam over your head.
The tender must ensure the neck dam is turned so
that the top edge is up and folded down (out) away

helmet, it must be removed before you can don the
helmet. To release the neck clamp, you must first
remove the safety pin that engages the latch catch
assembly.
Locate the ends of the chin strap before you put the
helmet on your head.
Adjust the neck dam so that it is turned up and out.
The neck dam is always turned up against the
diver’s neck. This is very important! With the neck
dam turned down, the helmet will vent air from the
neck dam causing the regulator to free flow. This will
make the helmet very uncomfortable.
With the diver holding the helmet, the tender should
now connect the quick disconnect fittings for the
bailout supply. Open the regulator adjustment knob
and the defogger control knob for a steady flow from
both just prior to the diver dressing into the helmet.
The diver should place the helmet face port down
and locate the tab on the end of the chin strap of the
head cushion. Loosen the tab completely. Grab the
base of the helmet with both hands while you hold
the head cushion open. Lift the helmet over your head
and carefully lower it.
Reach up inside the front of the helmet and tighten
the chin strap until it is just snug. The chin strap
tightens on the outside of the chin cushion. It does
not sit against the diver’s chin directly.
Push your head into the rear of the helmet. Then,
pull the helmet down and from side to side until it
is comfortable on your head. Position the chin strap
under your chin.
Spread the head cushion so that it is easier to don
the helmet.
Pull the strap down and back towards the divers right
until it is snug, but comfortable. Reach up inside the
helmet and fasten the strap under the divers chin by
attaching it to the Velcro tab on the right side of the
head cushion.
Take care to prevent the end of the strap from becoming fastened between the helmet shell and the neck
dam. Tucking the end into the helmet will ensure this.
In particular, the tender should watch for this. Make
sure the chin strap bolts directly to the helmet. If not,
Be sure to fasten the chin strap. If the
chin strap is not fastened properly, the
helmet will oat up on the diver’s head.
This can make the helmet very uncomfortable.

replace it at the earliest opportunity.
Lift the helmet over your head.
The rear hinge tab must engage the alignment sleeve.
Tilt your head back and push the entire yoke/neck
clamp assembly backwards on your neck. This is to
engage the hinge tab on the alignment sleeve. The
front edge of the neck clamp should be under and past
the front edge of the helmet. Keep your head tilted
back, and lift the front of the helmet up with one hand.
The tender must locate the rear hinge tab on the back
of the yoke. Lift the rear hinge tab out away from the
helmet and up until it can slide over the alignment
sleeve on the back of the helmet. Slide the tab over
the sleeve.
If the hinge tab is not mounted on the
alignment sleeve correctly, the yoke/neck
clamp assembly could come off. Helmet
ooding may occur. Drowning and death
may result if the helmet oods.
The diver must hold the helmet down while the clamp
is swung to their right to fully engage it against the
bottom of the helmet. Note how the tender is supporting the clamp mechanism with their left hand.
The pull pin must properly engage the bail on the
neck clamp.
The safety pin must be installed prior to every dive.
The tender next grasps the handle on the neck clamp
assembly and swings it to the diver’s right. This action
will open the clamp fully.

If a safety pin is not used, there is a possibility the clamp on the yoke latching system could be inadvertently opened during
the course of the dive by unintentional
depression of the plunger lock. Helmet
ooding, drowning and death may result.
NOTE: KMDSI recommends that all old style “push
style” pin latch catch assemblies be replaced with
new Pull Pin Latch Catch part# 505-010. The old
push pin latch catch assemblies are no longer available nor are replacement parts.
Additionally the pull type latch catch should also
employ the use of the safety pin to avert accidental
opening of the latch catch during diving operations.
(Additional guidance is available by contacting Dive
Lab Inc. at (850) 235-2715 or E-Mail DiveLab@
aol.com.)
SuperLite® 17B
The yoke strap is positioned underneath the handle
on the helmet.
NOTE: If you are ready to dive, ensure the tender
installs the safety pin before you enter the water.
While maintaining pressure on both the helmet and
the clamp, swing the clamp handle to the diver’s left
until it passes “over-center” and closes. Open the
latch catch assembly by pulling out on the pull pin.
Lift up on the yoke assembly until the latch catch engages the bail on the neck clamp handle, and release
the pull pin. The spring loaded pull pin should bottom
in the latch catch assembly capturing the handle bail.
The helmet is now locked into place and the diver
can test the breathing system properly.
If used, the yoke strap is now placed over the top
of the helmet (but under the handle) and secured in
place. The yoke strap is standard on all 17B helmets
shipping after January 2004. It’s use is strongly recommended.
The loop on the adjustable end of the strap slides over
the yoke on the diver's right side. Tighten the yoke
strap by pulling down on the free end to help ensure
the helmet stays on properly.
Test the defogger system by turning on and off the
defogger control knob. The regulator should be adjusted by turning the adjustment knob out until a
slight steady flow starts, then back in until the flow
just stops.
Next, the demand regulator system is checked for
proper function: breathe in and out. Inhalation and
exhalation effort should be nearly unnoticeable. Press
in on the purge button in the regulator cover. This
should produce a strong burst of breathing gas.
Do not perform this test unless the diver
and their tender are stationed immediately adjacent to the diver’s air manifold
and you are certain the air is on to the
manifold. If the diver is unable to ow air
to the helmet, either through the umbilical or the bailout, they may not be able
to remove the helmet easily.
To break the seal in this situation, the
diver must put their hand between the
neck dam and the neck, and pull the neck
dam away from the neck. A tender must
be standing by to assist the diver in removing the helmet if needed. Suffocation
could result.
The diver must be satisfied that their helmet is working properly before they enter the water.
3.8.7 Sealing Integrity Check
If there is any doubt that the helmet is sealing properly, perform the following test prior to diving.
Turn the supply gas off at the dive control system and
bleed the umbilical.
With the neck dam and yoke on the diver’s neck, the
helmet is installed and the yoke is closed. When the
diver attempts to inhale, a suction on the neck dam
is formed, indicating they are achieving a good seal.
The diver must then turn the air on immediately so
that they can breathe. If the diver does not turn the
air on they will not be able to breathe, unless the neck
dam is pulled away from their neck.
To perform this test, the diver must have an assistant
standing by. The assistant should be in control of the
gas supply console in the event the diver needs air or
they must be ready to lend a hand. The diver must be
next to the dive control manifold so that the air may
be turned on instantly, or the diver must be ready to
run a hand between their neck and the sealing neck
dam in order to pull the neck dam away from the neck
to allow breathing.
The diver may wear the neck dam yoke assembly
without discomfort if they are standing by to make a
dive. However, the helmet itself must always be the
last thing put on before the diver enters the water.
Everything else must be ready to go before the diver
puts the helmet on so they won’t have to support the
weight of the helmet while out of the water.
3.9.2 Attaching the Umbilical to the
Harness
The umbilical must now be hooked to the diver’s
harness by means of a suitable clip that is bound to
the umbilical. Some divers and companies prefer
a quick release clip and others prefer a clip that is
screwed together so the diver cannot easily remove
it from their harness. The securing of the umbilical
keeps the pull of the hose at the diver’s harness and
not on the helmet.
SuperLite® 17B
Never dive without attaching the umbilical to some type of harness or clip on the
diver’s body. Never allow the umbilical
to pull on the helmet directly or the diver
could suffer a neck injury.
3.9.3 Diver Dons Helmet
The diver dons the helmet as per this chapter.
3.9.4 Diver Check Gas Flow Systems
The diver must check out the breathing system themself as the tender finishes dressing them. Operate the
defogger valve, the demand regulator, and the purge
button to assure yourself of proper operation before
entering the water.
3.9.5 Communications Check
The communications system, sending and receiving,
should be checked at this point.
The communications system must be functioning
properly throughout the dive.
3.9.6 Diver Ready
The diver is now ready to enter the water. They should
be assisted to the water if needed. If a welding lens
is being used, make sure it is hinged up all the way if
the diver is making a jump entry. We do not recom-
The umbilical must be properly attached to the diver’s
harness.
mend jump entries. A quick overall inspection by the
tender is done and the diver is given the OK.
SuperLite® 17B
3.9.7 Water Entry and Descent
The tender must make sure there is a sufficient length
of umbilical clear if the diver is using a jump entry.
There must be no chance of the umbilical hanging
up when the diver jumps. Also, the defogger valve
should be turned on to overpressure the helmet to
prevent the possibility of water pressure from inverting the helmet exhaust valve when hitting the water.
The diver must report to the surface immediately
after the entry. It’s a good policy to descend 10 or
20 FSW (3-6 MSW), pause and check the regulator
adjustment knob to ensure adjustment for the least
breathing resistance.
The purpose of this adjustment knob is to allow the
diver the ability to compensate for variations in
umbilical supply pressure. This adjustment device
operates by simply increasing or decreasing the
amount of spring bias tension on the demand regulator inlet valve.
This adjustment device is not intended as a minimummaximum device. Minimum and maximum applies to
supply pressure only. The adjustment knob should be
adjusted by the diver to be at the easiest breathing
setting at all times.
Diving a KMDSI helmet or band mask with a bias
setting greater than that just necessary to keep the
demand valve from free flowing increases the work of
breathing and reduces the diver’s ability to perform
heavy work.
Then the diver checks in with the surface before
descending to the job. If a closed bell is being used,
the diver enters the water from the bell and pauses
for a short time outside the trunk until they are sure
all systems are operating properly.
3.10 Emergency Procedures
3.10.1 Flooding
In the event of partial or complete flooding, the diver
may clear the helmet quickly by tilting the helmet
down and activating the defogger control knob.
Pressing in on the manual purge button in the center
of the regulator cover will evacuate water from the
regulator, if any remains.
The water dump valve is located under the regulator.
By placing this valve in the lowest position on the
helmet, water will exit more easily.
After clearing, cautiously check for additional flooding. If the helmet continues to take on water, return
to the diving station, swimming with the water dump
valve positioned at the lowest part of the hat: that is
with the diver’s face forward and slightly tilted down.
Keep the free flow knob on. This increases the air/gas
pressure slightly inside the hat and keeps the water
out. Any incoming water is automatically purged.
3.10.2 Inhalation Resistance
If breathing becomes difficult, adjust the demand
regulator adjustment knob, for easier breathing by
rotating the adjustment knob counter clockwise. If
the breathing does not get noticeably better, press the
purge button in the regulator cover. If a surge of gas
does not flow with this action, open the emergency
valve.
If the flow is noticeably better, immediately notify
topside that you are on emergency gas. Insure your
umbilical is clear and return to the stage or decent
line. The diver should stay in communication with
topside personnel and make preparations to abort
the dive. The console operator should check to ensure the supply pressure to the diver is at the proper
pressure.
During the decent the communications must be
checked again and the diver supply pressure should
be adjusted as necessary to maintain the required
over-bottom pressure. It may be necessary for the
diver to readjust the demand regulator by means of the
adjustment knob once at the work site to compensate
for the variation in umbilical supply pressure.
A stop of flow in the demand regulator usually indicates the main gas supply has stopped. The diver
should first open the emergency valve by turning
the knob. If there is still no flow from the demand
regulator, the defogger valve knob should be opened.
Keep in mind that if the defogger valve is left open,
the bailout bottle will drain very quickly, particularly
if the diver is deep.
DANGER
DANGER
Immediately notify topside, check to insure your
WARNING
umbilical is clear and return to the diving station using the emergency breathing supply. Avoid making
a rapid ascent if at all possible.
Once at the surface, or inside the bell, the diver may
remove the helmet if needed. Never ditch the helmet
underwater unless conditions absolutely require that.
Rapid ascent is dangerous. It can lead
to air embolism or decompression sickness. Air/gas embolism can cause immediate loss of consciousness and/or
death. Even on a no decompression dive,
a rapid ascent may cause decompression sickness. A diver must only make a
rapid ascent when they are in immediate
danger of death by drowning or asphyxiation.
Ditching the helmet underwater must be
avoided. If the diver ditches the helmet
underwater they will not be able to see.
In many instances, even if the air supply is interrupted, topside will be able to
get it back on line quickly. Do not ditch
the helmet underwater unless you are
completely out of breathing gas and it is
impossible to return to the surface due
to entanglement of your equipment or
similar circumstances.
SuperLite® 17B
3.10.4 Demand Regulator Free Flow
If the demand regulator free flows, adjust the knob
in (clockwise) until it stops. If the free flow cannot
be stopped, the dive should be aborted. Even if there
is no serious problem to the diver, the dive should be
aborted and the problem with the regulator corrected.
3.11 Post Dive Procedures
3.11.1 Removing the Equipment
After the diver is well clear of the water they may
remove the helmet. If the diver is working out of a
stage they must not remove the helmet until the stage
is on deck.
3.11.2 Removing the Helmet
On the SuperLite
remove the safety pin before you can remove the
helmet. Slide the pin out and away from the latch
catch. Release the yoke safety strap.
The tender should assist the diver by pulling out on
the pull pin knob on the latch catch assembly. This
will allow the let the yoke to fall away. Next grab the
handle on the neck clamp assembly and pull outwards
away from the helmet, until the handle is in front of
the diver’s face. This action will break the seal of
the neck dam around the base of the helmet and the
neck dam and clamp will fall away from the bottom
front of the helmet.
While having the diver tilt their head back, reach
behind the back of the helmet and lift the rear hinge
tab off the alignment sleeve in the back of the helmet.
When you’re wearing the helmet, once the neck
clamp is open, you must reach underneath the front
of the helmet and loosen the chin strap that holds the
helmet in position. Then, lift the helmet over your
head using both hands, one on either side of the helmet to support its weight.
®
-17 A/B, the tender must first
Never remove the diving helmet while you
are in the stage. If you fall out of the stage
with the helmet off but still attached to
your harness it may be very difcult to
swim. Drowning may result.
After the helmet is removed, the tender can take it
from the diver and carefully lay it aside, on a soft
surface, such as a coil of the umbilical.
Next, reach in and spread the neck dam, pulling
against the sides of the neck dam with the palms of
both hands. Lift the neck dam over your head. Slide
the yoke backwards away from your neck to remove
it.
The diver’s harness and EGS cylinder is then removed. The emergency gas supply hose may be
disconnected while the diver leaves the helmet on
or while they hold the hat after removal. The quick
disconnect makes this procedure very easy.
3.11.3 Storage of the Helmet Between
Dives
The helmet should be maintained per the daily maintenance section in Chapter 6. Also, check the Dive
Lab post dive checklist A2.4 at www.divelab.com.
If the helmet is not going to be used for a period of
time, the head cushion, should be removed. The head
cushion should be dried and replaced in the hat before
storage. The regulator adjustment knob should be
unscrewed all the way out (counterclockwise) until
the next dive.
When the helmet is completely dry, or the diver is
ready to leave the job, the helmet should be stored
in the carrying bag to protect it.
If the head cushion becomes wet it may be dried out
by removing it from the helmet, squeezing excess
water out, and letting the head cushion hang dry or
putting it in a clothes drier on air dry only.
Once you have removed the helmet, spread the neck
dam to remove it.
Use only the air dry setting when drying
head cushion foam in a drier. Use of a
higher setting could cause the foam to
melt or start a re.
Kirby Morgan diving helmets are highly reliable life support equipment which should not malfunction if proper
preventative maintenance procedures are followed. Most problems encountered in using the helmet can be
easily remedied. The following information covers most potential operating difficulties.

Routine and preventative maintenance is critical and
must be done on a regular basis. All parts and components of the helmet have a useful service life and
eventually will require replacement. Some items,
when properly maintained, can go many years before replacement becomes necessary. Each helmet
or mask should have a logbook that tracks the usage,
maintenance and repairs.
It is essential to safety of the user that a routine and
periodic schedule of maintenance, inspection, and
testing be carried out. Helmets should be inspected
pre-dive on a daily basis. Helmets in continuous use
around the clock should be rotated out every 24 hours
and have a daily pre-dive inspection performed. Post
dive cleaning and inspections should be completed
each time helmet or mask use is finished for the day.
To minimize the spread of germs, sanitizing should
be performed after use, and in between use by different divers. Sanitizing procedures and recommended
solutions are described and explained in the General
preventative section of each KMDSI helmet and mask
manual. If the user is in doubt about the serviceability
or has questions in general, please contact your local
KMDSI authorized repair facility or KMDSI at Tel.
805-928-7772. Check the Dive Lab website at www.
divelab.com for the most up-to-date maintenance
procedures.
KMDSI Maintenance Checklist are located on the
KMDSI and Dive Lab websites. The checklists are
intended for all helmet and mask models. There are
also checklists for the KMB-18/28 band masks which
are done up the same as the helmet checklists.

The checklist can be laminated placed on a clipboard
and checked off with a grease pencil. Completion
should be logged in both the supervisors log and
the helmet or mask log book. The daily pre-dive is

A2.2 checklist on a monthly or as directed by the A2.2
and / or anytime serviceability of the helmet or mask
is in doubt. Helmets or masks used in contaminated
waters or for welding, burning, and jetting operations
will require service and inspection more frequently. If
a situation arises that casts any doubt as to the serviceability of a part or component it should be replaced.
Use the appropriate manual for the model helmet or
mask being serviced.
5.3 Yearly Maintenance
5.3.1 Overhaul/Inspection Checklist A2.1
The A2.1 checklist procedure fulfills all requirements for complete inspection. The checklist should
be performed at least annually and or more often if
daily and monthly inspections reveal signs of excessive corrosion, contamination, improper operation or
signs of damage or if the helmet log shows the unit had
previously been used in a questionable environment.
The daily and monthly inspections will determine
the necessity for overhaul with greater accuracy than
simply placing a number of hours on the overhaul
schedule. All O-ring’s, exhaust valves, and soft goods
should be replaced at least once a year. In between
overhauls the soft goods can be cleaned inspect and
reused providing a careful inspection reveals no
damage or deterioration. Again, logged questionable
previous diving environments will be determining
factor as well. The A2.1 checklist should be filled out
and retained in the maintenance files and provides
an excellent record of maintenance. All maintenance
should be annotated in the helmet log.
The Overhaul Checklist Procedure A2.1 is intended to
aid persons performing routine overhauls of KMDSI
SuperLite
®
Helmets and Band Masks. The checklist
should be used in conjunction with the applicable Operations and Maintenance Manual for the model helmet being serviced and is primarily intended to guide
and document the maintenance as it is completed.
Specific detailed procedures for each section of this
checklist can be found in the Operations and Maintenance Manuals. This checklist when completed
should be retained in the equipment maintenance files
and the helmet or mask log book should be updated.
The checklist’s are intended to be used for all models
of KMDSI SuperLite
®
and KM Helmets and band
masks. All KMDSI helmet and band mask manuals
can be downloaded free at www.kirbymorgan.com.
This section covers the preventative maintenance
necessary on the SuperLite
both A&B. A helmet that is kept clean and in good
repair will offer far better service to the user. This
helmet is designed for easy access to all areas for
proper inspection and servicing. Numbers appearing in parenthesis below are “location” numbers that
are used in the blow apart illustration at the rear of
this manual.
6.2 Required tools, Cleaning Agents,
Lubrication
All KMDSI helmets and masks are designed with the
professional diver in mind. Most maintenance can be
performed by the diver using common tools and this
manual. There are some repairs however, that must
be accomplished only by KMDSI authorized repair
facilities. This includes fiberglass and helmet neck
clamp repairs, and face port inserts. For technical
assistance please telephone your nearest authorized
dealer or call KMDSI at (805) 928-7772.
Every diver should carry sufficient tools and spare
parts to maintain their helmet in top working condition. It is very impor tant to use wrenches of the correct
size rather than adjustable wrenches when possible.
Adjustable wrenches tend to slip and can round the
edges of soft brass parts. The following wrenches and
tools are required to maintain the SL 17:
Torque wrench with the following attachments:
1 3/8 inch crows foot
7/16 inch open end wrench
9/16 inch open end wrench

The helmet and components should only be cleaned
using a mild solution of dishwashing soap such as
JOY ™ or Dawn ™ hand dishwashing soap.
Parts that have corrosion should be washed and
scrubbed with a nylon bristle brush and then soaked
in a solution of 50% white vinegar and water for 3060 minutes followed by a light brushing and a good
fresh water rinse. Helmet liners and rubber components should be cleaned using a mild soapy solution
followed by a good rinsing and air-dried.
DO NOT use hair dryers or high heat to dry the
rubber or fabric components, high temperatures will
severely reduce their serviceability. To clean parts
heavily encrusted with salt we recommend a dilute
solution of white vinegar and a toothbrush.
6.2.2 Component and Parts Lubrication
All helmets are lubricated at KMDSI with Christo-
®
Lube
. Helmets used for air diving or diving or with
oxygen mixtures containing less than 50 % oxygen
can be lubricated with food grade silicone such as
Dow Corning
®
111 or equivalent.
Do not use aerosol spray or lubricants. Many aerosol propellants will damage plastic. Avoid lubricant
contact with plastic parts.

be taken to avoid contamination of gas
system components with hydrocarbons
when air is used as a breathing medium.
Contamination of Kirby Morgan masks
and helmets with hydrocarbons can lead
to re or explosions when this equipment
makes contact with high oxygen partial
pressures.
All parts on Kirby Morgan helmets and

NOTE: All parts on the helmet that require
lubrication must be lubricated sparingly with the
appropriate lubricant.
Silicone lubricant is not recommended for helmets
used with oxygen. (Avoid mixing lubricants to
preclude incompatibility)
All pipe thread fittings used on our helmets, masks
and components require sealing with Teflon

Do not allow any excess Teon® tape
to cover the end of the pipe thread ttings. Loose pieces of Teon
®
tape can
interfere with the performance of helmet
components and may block the diver's air
supply. This could lead to death through
suffocation.
6.3 General Cleaning & Inspection
Procedures
Each diver must establish their own minimum standards for the care of their helmet. We offer recommendations here with the suggestion that the diver
establish for themself what is necessary to provide a
good working unit. Use of the helmet in fresh water
will require a timetable for maintenance procedures
different from that when the helmet is used in salt
water.
Using the helmet in sea water while jetting in sand
will necessitate increased maintenance. Use of the
helmet in a heavy oil and/or chemical environment
may make it necessary to replace rubber parts to assure proper function. Regardless, all helmets should
be disassembled, (with the exception of the weights)
cleaned and inspected for damage. All soft goods
(o-rings, exhaust valves, and diaphragm) should be
should be changed in accordance with the Dive Lab
Checklist A2.1. Any parts that have excessive wear
or corrosion should be replaced.
Use only thin Teon® tape to avoid damage to threads.
6.2.4 RTV Sealant
Certain components used in KMDSI helmets and
masks use RTV adhesive / sealant to provide bonding
and sealing. KMDSI recommends Dow Corning
®
™
RTV 732 multi purpose sealant or equivalent. When
sealant is applied the user must use care to insure
excess sealant is wiped clean so as not to interfere
with other components. Sealant should be allowed to
cure for 24 hours before equipment is used.
6.2.5 Thread Locker
KMDSI recommends Loctite
®
222
as the thread locking compound
that should be used on components
that call for a thread locker. Threads
should be clean and dry prior to applying thread locker. Avoid Contact
with Polycarbonate Plastics (Face
Port)
Ensure that all excess thread locker
has been removed. Allow thread
locker to cure for at least 3 hours
prior to using the component.
NOTE: Certain fuel oils and/or chemicals will cause
premature degradation of soft goods and seals by making
them become soft, swell or break down. Upon exiting the
contaminant, KMDSI recommends a thorough external
decontamination/washing of the helmet/neck dam yoke
as soon as feasibly possible, followed by a vigilant inspection of the interior of the helmet to ensure that no
contaminant has entered.
Pay particular attention to the following parts prior to
re-use; the Quad-Valve™ assembly, demand regulator
diaphragm, demand regulator exhaust valve, communications post(s) or communications connector assembly,
and neck dam.
If in doubt about the serviceability of a part,
repair or replace it immediately. Use
only Genuine Kirby Morgan replacement
parts. The use of unauthorized parts may
result in injury or death to the user.
Do not use solvents or bleach for cleaning. These agents are toxic and use of
them may result in injury or death to personnel and damage to equipment.
Wear eye protection to
prevent cleaning and
germicidal cleansing
solutions from contacting eyes. If contact
occurs, rinse eyes with
copious amounts of water and consult
medical help immediately.
Cleanliness is imperative in maintaining and
handling Kirby Morgan masks and helmets.
All tools, parts, and components must be
kept free of oil, lubricant, rust, and other
contamination. Foreign substances within
an assembly may result in equipment failure
and possible injury or death to personnel.
Different brands of lubricant should never be
mixed. Ensure all old lubricant is removed
prior to applying new lubricant.
6.3.1 O-Ring Removal/Inspection/Cleaning
and Lubrication
Strict cleanliness and proper lubrication are extremely important during O-ring installation. Comply with the following instructions to ensure proper
installation:
NOTE: Ensure all parts are clean throughout the
assembly procedure. Dirt or loose particles in the
O-ring groove can cause leaks in the seal and damage to the O-ring, reducing its life. During cleaning
of equipment, carefully clean O-ring grooves, using
a soft bristle brush and mild soap solution.
O-Ring Removal:
Do not use screwdrivers or hard metal picks to remove
O-rings. When possible, only use fingers to remove
O-rings. If an O-ring fits too tightly in its groove to
be removed using the fingers, use the appropriate tool
from an O-ring removal kit (brass pick).
A plastic cable tie makes an effective O-Ring removal
tool. Use of an appropriate tool helps prevent scratching the O-ring groove, which can cause leakage or
premature failure of the seal.
O-Ring Inspection:
If during routine corrective maintenance O-rings are
to be reused, only reuse O-rings that pass a visual
inspection. Inspect for deformities or compression
set, hardening or brittleness, nicks or cuts, pits or blisters, or any other signs of damage. Cut and discard
damaged O-rings and replace them with new ones.
O-Ring Reuse:
All O-rings and soft goods should be replaced
whenever scheduled overhauls are being completed.
During routine repairs or maintenance in between
the overhauls, O-rings and soft goods may be reused
after cleaning provided a careful inspection reveals
no wear or damage.
Place the O-rings in a cleaning basin, cover with
mild mild soap solution, and brush gently with a soft
bristle brush to remove all traces of old lubricant and
contamination. Rinse cleaned O-rings with fresh
water and wipe clean with lint-free cloths, then allow to air dry, carefully inspect for cracking, cuts,
abrasions and deformities. Replace O-rings if any
damage is found or suspected.
6.3.2 General Cleaning Guidelines
Cleaning and sanitizing of the helmet should be accomplished upon completion of use and/or prior to
storage. Clean is defined as free of dirt, rust particles,
lubricant and oil and other contaminants as viewed
by the unaided eye.
Sanitizing is defined as eliminating germs and microorganisms. Sanitizing should be accomplished
post use or prior to use by another user. KMDSI
recommends sanitizing be accomplished any time
the unit is to be used by another person during the
mission or operation.
NOTE: The Sanitizing Procedure should be accomplished if possible between uses by different users
during the same operation.
Always sanitize the helmet
prior to use by another
person. Failure to do could
result in the transmission of com m u nicable
diseases, some of which
6.3.2.1 Mild Soap Solution for
General Cleaning and Leak Detector Use
Maintenance procedures include cleaning with a
general-purpose solution of a mild diluted hand
dishwashing soap such as Joy or Palmolive. Cleaning
solution is prepared by mixing approximately one
teaspoon of soap to 1/2 gallon of warm fresh water.
This solution may also be used as a leak detector
solution. Place all parts and components in a clean
washbasin or sink and immerse in soap solution.
To properly sanitize the demand regulator between
use by different divers, the regulator cover and diaphragm must be removed, as well as the oral nasal
mask. These items must be submerged in sanitizing
solution and agitated as directed in the sanitizing
procedure. Use a spray bottle and spray the interior
of the demand regulator with the sanitizing solution,
too. Allow all parts to be wetted for a minimum of 10
minutes before thoroughly rinsing with fresh water.
SuperLite® 17B
6.3.2.3 Germicidal Cleaning Solutions and
Procedure
Sanitizing of the oral-nasal mask/regulator of KM
37 is accomplished using one of four approved germicidal cleansing solutions. There are four examples
of solutions shown below, along with the necessary
ordering information and mixing instructions.
In almost all cases, germicidal solutions must be
diluted. See the manufacturer's directions for use.
NOTE: Ensure helmet liner and cushion are
removed prior to sanitizing the oral-nasal mask/
regulator.

The microphone and interior of the helmet should
also be wiped down with a clean rag which has been
dampened in sanitizing solution. Follow this after 10
minutes with a clean rag which has been dampened
in fresh water.
Allow parts/components to soak for at least five minutes, and then scrub using a nylon brush. Carefully
brush all surfaces, paying close attention to O-ring
grooves and threaded surfaces ensuring all lubricants
are removed. Regardless of the soap used, all components must be thoroughly rinsed post cleaning to
remove all traces of soap.
After cleaning, allow the regulator, diaphragm, and
cover to dry before reassembling.
6.3.2.2 Acidic Cleaning Solution and Procedures
Metal parts that have visible corrosion should first
be cleaned using the soap solution scrubbed with a
nylon bristle brush, then soaked in a solution of 50%
white vinegar and water for less than 60 minutes.
They may also be placed in a ultrasonic sink followed
by a light brushing and thorough rinsing with fresh
water and air-dried. If corrosion is such that 50/50
vinegar will not clean components, it will be best to
replace the components.

Sanitizing Procedure:
Unless otherwise directed, use the following procedure to disinfect the oral-nasal mask/regulator:
1) Wet or immerse all components to be sanitized.
Allow components to stay in contact with the solution
for at least 10 minutes.
Germicidal cleansing solutions must be
carefully diluted if required in accordance
with the manufacturer’s recommendation. If solution is not of the recommended strength, it will not act as an effective
disinfectant. Failure to thoroughly rinse
germicidal cleansing solution from diving
equipment may result in lung irritation
and/or long-term degradation of rubber
and silicone components of this equipment.
2) If the solution appears to be drying, apply more
solution to keep it wet for the full 10 minutes.
3) After 10 minutes, thoroughly rinse components
under running potable water.
NOTE: The purpose of this procedure is to sanitize the components exposed to each of the divers.
KMDSI recommends sanitizing be accomplished
daily in between use by different divers, after each
use, or when future use is anticipated within the
mission (job) period. KMDSI defines “A mission
is defined as use of the helmet over a seven-day
period.”
The following steps must be performed daily at the
completion of diving operations.
1) Disconnect the helmet from the diving hose and
EGS cylinder. Make sure the air is off and the breathing system of the helmet is unpressurized. To vent the
system, open the defogger valve knob and emergency
gas valve knob until all gas flow stops.
2) Place a protective cap over both the air inlet and
the emergency valve inlet to prevent foreign matter
from entering the valves.
4) If the head cushion is wet, the chin cushion is
probably wet, too. Like the head cushion, the chin
cushion is fastened into the helmet with snaps. Remove it from the helmet, rinse it with fresh water,
and allow it to dry.
5) Remove the earphones from the retainer clips.
Avoid getting water on the oral nasal microphone
and earphones. Remove the earphone covers from
the earphones so they can dry completely.
Cover the air inlet and emergency gas valve openings with
dust caps when not in use.
Never disconnect any hose from the helmet unless all gas has been vented from
the hose rst. If the hose is disconnected
with pressure in the line the ttings may
be damaged. In addition, the hose can
whip about causing injury to anyone
standing nearby.
3) If the head cushion is wet, remove it from the helmet and rinse it with fresh water. The head cushion
is fastened into the helmet with snap tabs and pulls
out easily. To ensure that the head cushion is dry for
future use you may want to remove the head cushion
foam. However, do not remove the foam unless it
is absolutely necessary. The head cushion will dry
properly without removing the foam.
Remove the foam for the head cushion if wet.
Uncover the earphones so they may dry.
Wash the microphone with a mild solution of soapy
water, followed by a rinse with fresh water.
6) Wash the exterior of the helmet with a mild soapy
water solution. Rinse the exterior of the helmet
thoroughly with fresh water. Turn the defogger
valve knob, emergency valve knob, and regulator
adjustment knob while rinsing to prevent salt from
accumulating under these valves.
7) Remove the regulator cover, clamp and diaphragm,
and wash the interior of the regulator with a mild
solution of soapy water. Run water through the air
delivery tube located in the oral nasal.
Do not depress the purge button while rinsing the
regulator as this action will permit foreign matter
back into the inlet valve and seat.
8) Wash the interior of the helmet and oral nasal
mask with a soapy water solution and rinse with
fresh water.
9) Screw the demand regulator adjustment knob all
the way out. This will prolong the life of the inlet
valve seat and keep the internal adjustment correct.
Close the emergency valve and steady flow valves.
12) If the neck dam is damaged it should be replaced.
13) Operate the neck clamp and latch catch as you
rinse these items with clean, fresh water.
14) Wipe all surfaces with a clean, dry towel to remove water droplets and allow to dry.
10) Lubricate the shaft of the nose block device with
silicone lubricant.
11) Rinse the neck dam assembly and allow to dry.
Remove the O-ring from the bottom of the helmet,
clean and lubricate.
Avoid patching a torn or punctured neck
dam. If the patch comes off underwater the
helmet could ood and/or cause the demand
regulator to freeow. Serious injury, drowning or death may result. A damaged neck
dam should be replaced.
The nose block O-rings must be regularly lubricated.
The neck clamp and latch catch must operate properly. They
must be regularly inspected and serviced.
The o-ring on the base of the helmet must be in good
condition.
The exhaust system on your helmet requires regular
attention. It should be inspected and serviced every
month.
1) Remove the whisker clamps (or tie wraps) that
secure the whiskers.
2) Carefully cut the tie wrap that connects the Quad
exhaust cover to the exhaust main body.
SuperLite® 17B
Use only KMDSI original replacement
spares when repairing your helmet. The
use of other manufacturer’s parts will interfere with the performance characteristics of your life support equipment and
may jeopardize your safety. Additionally,
any substitutions will void all warranties
offered by KMDSI.
3) Remove the two screws that hold the Quad exhaust
cover to the exhaust body.
4) Remove the Quad exhaust cover and inspect the
exhaust valve.
Inspect the exhaust valve for cracks or tears, replace
if needed. Lubricate the valve with a small amount
of silicone lubricant. Rub the lubricant into the valve
thoroughly leaving no excess lubricant to collect sand
or other debris.
Port retainer
5) Reinstall the Quad exhaust cover so that it connects to the exhaust main body and the exhaust body.
6) Install the screws and tighten to "12" inch pounds.
7) Install the tie wrap that fastens the exhaust main
body to the Quad exhaust cover and tighten until
snug.
8) Install the whisker clamps properly and tighten.
See Chapter 7 for this procedure.
Without gas to the helmet, check “exercise” the
Emergency Gas Supply valve ensuring the valve
operates smoothly. Replacement/overhaul guidance
will be found in Chapter 7 of this manual.
6.5.3 Steady Flow/Defogger Valve
Without gas to the helmet, check, i.e., “exercise”
the Steadyflow/Defogger valve ensuring the valve
operates smoothly. Replacement/overhaul guidance
will be found in Chapter 7 of this manual.
6.5.4 Bias Device Adjustable Section of
Demand Regulator
Remove the regulator cover clamp, cover and diaphragm and inspect the interior of the regulator body
for corrosion and contamination. Carefully inspect
the diaphragm for cuts, tears and deterioration. If
any damage is present replace the diaphragm, per
Chapter 7 of this manual.
Attach an air source to the umbilical adapter and
set the supply pressure to between 135-150 p.s.i.g.
(9.3-11.4 bar). Adjust the regulator knob out, until
a slight free flow develops, then, adjust in until the
free flow just stops and check the lever play. It should
be between 1/16” – 1/8” (1.5 – 3.0 mm). Adjust if
necessary, per Chapter 7. Reinstall the diaphragm,
the cover and the clamp.
6.5.5 Neck Clamp and Yoke Assembly
Inspect the neck clamp and yoke assembly and test
for proper operation per Chapter 8 of this manual.
6.5.6 Latch Catch Mechanism
Inspect the latch catch mechanism and test for proper
operation per Chapter 8 of this manual.
This chapter covers the maintenance and repair of all
components of the breathing system. The breathing
system includes the one way valve, the emergency
valve, the side block, the bent tube assembly, the
demand regulator, and the oral nasal mask.
The breathing systems on all Kirby Morgan helmets
and masks are simple and highly reliable. The fact that
they can continue to operate when the components are
not in a well-maintained condition can cause divers
to become complacent about maintenance.
SuperLite® 17B
Never use pliers to work on the one way valve.
Your life depends on the correct function of this
equipment!
While Kirby Morgan helmets and masks are simple
to maintain, like any type of life support equipment,
they do require regular periodic maintenance to function properly.
All parts disassembled should be thoroughly cleaned
using the methods described in the Appendix in the
rear of this manual. Components that require the use
of lubricants, sealing and thread locking compounds
should also be maintained.
Most fasteners have a torque value, it is imperative that
all fasteners which have a torque value be tightened
to the torque specifications as outlined by the procedure, or as listed in appendix 1. If in doubt as to the
proper torque setting, contact your local authorized
repair facility or KMDSI.
7.2 One Way Valve
NOTE: The one-way valve assembly should be disassembled, cleaned and the three O-rings should be
replaced at least annually. Damaged and/or corroded
parts should be replaced. A repair kit is available for
replacement parts (525-330).
Use two wrenches or hold the hex part
of the body in a vise while removing or
turning the seat with a wrench. Do not
use pliers on the main body of the oneway valve. You may damage the valve if
pliers are used.
(If no vise is available use a backup 1 inch open end
wrench)
To disassemble and inspect the one way valve assembly:
1) The one way valve assembly must be removed
from the side block. Use the open end wrench to
remove it.
2) After the one way valve has been removed, use two
wrenches or hold the hex part of the body in a soft jaw
vise while removing the seat with a wrench.
As the seat is removed, the wiper and the O-ring will
slide out in place in a groove on the seat. The poppet
and the poppet O-ring usually come out in the seat
being followed by the spring.

to prevent foreign materials from sticking to these
components.
6) Replace the spring.
7.2.2 Reassembly of the One Way Valve
1) Slide the new O-ring over the poppet.
2) Insert the new spring into the valve body, followed
by the poppet.
3) Next, install the new O-ring and new wiper on the
seat. Thread the seat into the valve body.
4) Tighten the seat to 150 inch lbs. (17 Newton meters) with a torque wrench while holding the body in
a soft jaw vice or wrench.
5) If the adapter has been removed, it must be cleaned
and wrapped with Teflon
®
tape.
Tighten to 150 inch lbs. (17 Newton Meters) with a torque

6) Test the operation of the valve.
7) Place the new O-ring on the end of the one way
valve assembly and reinstall the valve assembly in
the side block. Tighten to 150 inch lbs. (17 Newton
Meters) with a torque wrench.
Do not allow any Teon® tape to cover the
end of the adapter, or to enter the oneway valve. Loose pieces of Teon
®
tape
can interfere with the performance of the
one-way valve or the regulator and may
block the diver’s air supply. This could
lead to death through suffocation.
The side block should be overhauled at least annually,
or whenever components show signs of wear, damage
or do not function smoothly or properly. Minimum
replacement components during overhaul includes
all O-rings. A repair kit is available for replacement
parts (Part #525-311).
The side block does not require removal from the
helmet each time an overhaul is being conducted
providing inspection of the internal passages does not
reveal contamination or excessive corrosion. However, the side block should be completely removed at
least every three years of active use to ensure fasteners
are not corroded or frozen.
The side block assembly is held in place on the helmet
shell by a stud, flat washer, lock washer, nut, and a
machine screw. The screw does some securing but its
main function is to prevent rotation of the side block.
The stud also extends into the interior of the helmet
shell far enough to secure the air train by means of
the washer and nut.

3) The stud nut is removed next, with the lock washer
and flat washer.
4) Next, the alignment screw is removed.
NOTE: The alignment screw is located in a recess in
the fiberglass next to the stud. In older helmets without
the air train gasket, this recess was normally filled with
RTV. The RTV, if present, must be scraped free to reveal
the screw.
Do not use a screwdriver or chisel to remove the
sideblock as damage to the shell could result. Be
sure to peel or scrape the old silicone sealant away
from both sealing surfaces before reassembling. Acetone helps remove this, but must be used sparingly
since it will also remove the flat black finish inside
the helmet.
6) If you plan to rebuild the side block assembly, it
should be done at this time, while the side block is off

all precautions listed on the silicone sealant tube and Material Safety Data Sheet.
Do not dive the helmet until the sealant
has had time to cure. Check the directions on the tube of sealant for curing
time. If the helmet goes into the water
before the sealant has cured it could leak
through the side block mounting stud
hole, screw hole, or air ow hole. This
could lead to drowning.
If silicone sealant is blocking the air ow
into the helmet it must be cleaned out. If it
is not, the diver may not be able to properly defog the helmet or clear a ooded
helmet quickly. In addition, if the demand
regulator is not delivering air properly, the
diver cannot use the free ow system as
a source of breathing air. This could lead
to suffocation.

3) When the packing nut is free of the threads of the
emergency valve body, back out the stem until it is
free of the emergency valve body.
7.5.2 Cleaning and Lubricating
1) Clean all the metal parts in a soap and water solution, followed by cleaning with a 50/50 dilute solution
of white vinegar/water. Rinse with fresh water. Clean
all parts. See the cleaning instructions in Chapter 6.
2) Inspect the packing and washer for wear and replace if necessary. Normally the packing will last a
very long time and does not require replacement as
long as the valve operates smoothly and does not leak.
To replace the packing place the packing nut in a vise
and carefully work the packing out with a small screw
driver, taking care not to damage the threads of the
packing nut. Replace the washer if needed.
3) Inspect the stem seat for unevenness or wear and
replace if necessary. It must also be replaced if the
stem is bent. Damage will include damaged threads,
rounded flats that engage the control knob. Also
Remove the lock nut, spring and knob.
inspect the shaft to ensure the conical seat surface is
smooth and free of corrosion or damage.
Undo the packing nut. Inspect the packing and washer.
4) Check the seat in the emergency valve body for
wear or unevenness, galling and corrosion. Check the
seat on the emergency valve stem. To clean up the
seat surface use a pencil eraser to buff the surface.
Inspect all threaded surfaces for damage. Replace
the emergency valve body if any damage is found.
5) To remove the emergency valve body from the
side block the one way valve assembly must first be
removed.
6) If the emergency valve body is then removed, clean
and inspect the pipe thread and inspect for damaged
threads, cracking or distortion. Replace the emergency valve if any damage is present.
Re-tape threads with Teflon

tape, 1 ½ wraps starting two threads back, tighten using good engineering
practice. To reinstall the emergency valve body onto
the side block, the one-way valve assembly should
not be installed.
7.5.3 Reassembly of Emergency Valve
1) Lightly lubricate the stem threads in the body as
well as the bonnet threads.
2) Replace the washer and packing on the stem, then
lightly lubricate the stem shaft and threads.
Installing the packing nut on the valve stem.
NOTE: There are two different packing (s) and
washers supplied in the kit (525-311), for rebuilding both the older style and the newer high flow
emergency gas valve. Match the removed packing
and washers to the new ones supplied and discard
the others.
3) Holding these components in place on the stem,
screw the stem into the emergency gas valve body.
4) Rotate the stem until it is seated all the way in then,
back it out -1/2 turn.
5) T
hread the packing nut onto the emergency valve
body. Run the nut in and tighten slightly with a wrench.

for the appropriate valve.
SuperLite® 17B
11) Before wrapping the threads with pipe tape, check
the fit of the valve assembly pipe threads to the mating
threads of the side block. There should be 2 turns of
hand make up before needing to use a wrench.
If there is less make up, call your nearest KMDSI dealer
or Dive Lab for advice.
6) Inspect the emergency gas valve knob for wear and
damage. Ensure the flats that engage the valve stem shaft
are not rounded, cracked or damaged. The valve knob
should not have rotational play greater than of a turn.
NOTE: This knob is not interchangeable with the
defogger valve knob.
7) Place the emergency gas valve knob onto the stem
and rotate the stem all the way out, then back again.
The rotation must be smooth. If “hard spots” or unevenness are felt during the rotation, the stem may be
bent and could need replacement.
8) Tighten the packing nut with a torque wrench until
moderate resistance is felt when turning the knob.
Torque to 50 inch pounds after seating.
9) Place the spring, and locknut onto the stem securing the knob.
10) Tighten the locknut until its top is flush with the
top of the knob. The assembly is now complete and
ready for testing.
NOTE: At this time, with the valve separated from
the sideblock, testing of the emergency gas valve is
easily accomplished by attaching the valve, by itself
in the shut position, on to the bail-out whip from the
first stage. Pressurized to a minimum 135 p.s.i.g. (9.3
bar) using the EGS Cylinder and dropping it into a
bucket of clean water a minimum 30 seconds to check
for leaks.
Use only thin Teon® tape when installing
the Emergency Gas Supply valve in the
side block. Thick tape can lead to thread
damage, which may make it impossible
to install the EGS valve in the side block
properly. This could lead to a loss of
breathing gas.
12) Before installing the valve assembly, wrap the pipe
threads with 1 ½ turns of Teflon
first thread. Apply the tape with slight tension to allow
the tape to fill into the threads.
Hand tighten the valve, then continue an additional 1
½ to 2 turns with a wrench keeping in mind the proper
alignment of the control knob to the side block. Also,
there should be at least one male thread visible. Check
to be certain the valve is tight by trying to loosen the
fit by hand.
DO NOT TIGHTEN

AN NECESSARY!
OVERSTRESS THE PART AND CAUSE THE PART
TO FAIL.
It is NOT necessary to have the control knob for the
emergency gas supply valve perfectly “square,” i.e., at
a 90 degree angle to the side block. Any angle is acceptable provided that 1) the valve handle can be turned
easily and 2) the diver can locate the handle easily.
7.5.4 Leak Testing the EGS Valve
1) Attach supply whip from the EGS first stage to EGS
helmet valve.
2) Ensure the defogger valve knob is open and the EGS
Valve is shut.
A leaking Emergency Gas Valve assembly can cause the diver to exhaust
their entire EGS (bailout) without their
knowledge. This may lead the diver to
mistakenly assume their EGS supply is
available when it is not. This could lead
to panic or drowning in an emergency.
Any worn or damaged components must
be replaced.
A sub mersible press ure gauge
should always be used with the EGS
system to help minimize this risk.
3) Pressurize EGS Valve to a minimum of 135 p.s.i.g.
(9.3 bar) using the EGS cylinder as supply. Allow system pressure to stabilize, and then shut the EGS supply
cylinder valve. Note time and final stabilized system
pressure.
4) Perform the leak check for minimum of five minutes, using the mild soapy solution, per Chapter 6.
Ensure there is no gas flowing or pressure drop in the
system. There should be no visible signs of external
leakage if the valve is operating properly.
7.6 Bent Tube Assembly
7.6.1 General
The bent tube assembly provides breathing gas flow
from the side block assembly to the regulator assembly. Both ends of the bent tube assembly disconnect
for complete removal. The O-ring and the Teflon
O-ring should be replaced during normal overhauls or
any time these components are deemed unserviceable.
®
7/8 inch Open-end Attachment on Torque Wrench
7/8 inch Open-end Wrench
1) Always start removal of the bent tube at the side
block end. The free swiveling mount nut on this end
of the bent tube can be unthreaded completely and
can slide down the tube.
2) The inlet nipple has a jam nut that locks the mount
nut in place. With one wrench, hold the bent tube
mount nut. With another wrench, turn DOWN the jam
nut, backing it away from the mount nut. The mount
nut can then be rotated until free of the regulator inlet
nipple threads. It can be pushed up the bent tube.
3) With the two mount nuts free; the bent tube assembly can be pulled straight out of the regulator inlet
nipple. The bent tube assembly can be rotated back
and forth to aid removal.
These components do not require replacement during
field repairs providing a careful visual inspection does
not reveal wear or damage. All soft goods should be
carefully cleaned in accordance with Chapter 6 prior
to inspection for reuse.
7.6.2 Removal of the Bent Tube Assembly
Tools Required:
11/16 inch Open-end Attachment on Torque Wrench
Clean the bent tube in accordance with Chapter 6.
The O-ring at the regulator end should be cleaned
and inspected whenever the bent tube is removed.
Replace the bent tube if it is excessively scratched
dented or compressed deeper than 1/8 inch. If the
helmet has been used for burning jobs, carefully check
for erosion of the metal or severe corrosion. Replace
if any erosion is present or integrity is in question.
Keep in mind the bent tube is a critical component
that routs breathing gas to the helmet systems.
7.6.4 Installation of the Bent Tube

O-ring at the side block end.
2) Push the regulator end of the bent tube assembly
into the inlet nipple. Slide it in until the side block
end of the tube is aligned with the threads for the
mount nut.
SuperLite® 17B
Replace the O-ring on the bent tube if it is worn or damaged.
Do not wrap the bent tube with tape,
ropework, springs, hose wrap, or other
items. This will prevent daily inspection
of the bent tube. In addition, some of
these items may trap moisture, which
could lead to corrosion and failure of the
bent tube.
If the tube fails, this could lead to a rapid
depletion of the diver’s breathing gas
supply. This could lead to serious personal injury or death.
3) Be sure the Teflon
®
O-ring is in place on the side
block end of the bent tube, then engage the threads
on the tube to the side block and hand tighten.
4) Start the “regulator to bent tube” mount nut onto
the inlet nipple of the demand regulator and run it in
by hand as far as it will go.
NOTE: Run the mount nut up on the inlet nipple hand
tight only.
5) Using a torque wrench, tighten the bent tube assembly mount nut onto the side block to (100 inch lbs).
6) Hold the mount nut on the end of the bent tube
with a wrench and tighten the jam nut against it with
a torque wrench to 40 inch pounds.
The hose assembly provides for breathing gas flow
from the Side Block Assembly to the regulator for
the SuperLite
disconnect for complete removal.
The block itself is no longer available, but replacement hoses, o-rings, and valve components are still
available. The block was discontinued in 2005. If
your “A” block is damaged, your helmet can be
converted to a “B” sideblock with only a few additional parts.
Regardless of the hose condition it must be replaced
at least every two years and o-rings should be replaced at least annually.

2) Disconnect the hose from the inlet nipple.
3) Loosen the hose at the side block connection.
The hose and o-rings must be inspected on a regular basis.
7.7.3 O-Ring Replacement
1) Remove the o-ring from the side block end of
the hose assembly by pinching it with your fingers
and sliding it up the threaded end of the assembly.
Install a new o-ring that has been lightly lubricated.
2) To remove the o-ring on the regulator end of the
hose, you will need to use an o-ring pick made of
brass or plastic. Care must be taken not to scratch or
damage the sealing surface on the hose fitting when
removing the o-ring. If the fitting is gouged it will
leak breathing gas.
7.7.4 Hose Assembly Replacement
1) Thread the hose assembly into the side block and
tighten with a wrench.
2) Install the hose assembly fitting onto the end of
the regulator inlet nipple. Tighten the fitting while
holding the nipple with a second wrench.
While the regulator systems on all Kirby Morgan helmets are simple and highly reliable, the breathing resistance will increase if the demand regulator on your
helmet is not maintained or adjusted properly. The
demand regulator must receive regular maintenance
to assure the best performance possible. However, in
the event the demand regulator is damaged, there is
always a backup supply of steady flow gas available
from the defogger valve.
If the regulator does not breathe easily, the diver cannot work hard and will tire rapidly. Simply put: If the
demand regulator does not work properly the diver
cannot work properly. This makes the maintenance
of the demand regulator assembly essential.
For the gas inlet valve and adjustment system to operate properly, the components in the demand regulator
MUST be in good condition and MUST be periodically inspected and adjusted.
Four special tools, the inlet valve holder (Part #525-
616), the regulator adjustment wrench (Part #525-611),
the socket wrench (Part #525-612), and the castle
wrench (Part #525-618) should be used to work on
the SuperFlow
®
regulator whenever possible.
7.8.2 SuperFlow® Demand Regulator Test
for Correct Adjustment, Fully Assembled
To maintain optimum performance of the demand
regulator, it should be checked for proper function
and adjustment prior to commencement of diving
each diving day, in accordance with the KMDSI Daily
Set Up and Functional Checklist. See the Dive Lab
website (www.divelab.com) for the latest procedures
for set-up.
Check the regulator for adjustment and proper function with the assembly complete, and supplied with a
breathing gas supply pressure of 135 to 150 p.s.i.g.
NOTE: 135 to 150 p.s.i.g. over ambient is the standard supply pressure to be used when adjusting all
KMDSI helmets and band-mask equipped with the
SuperFlow
®
regulator. See Chapter 2 for recom-
mended pressures during use.
NOTE: When storing the helmet for any length of
time, ensure that the regulator adjustment knob is
turned “out” fully counterclockwise to avoid stressing
the bias springs. This will prolong the life of both the
inlet valve, seat, and bias springs.
1) Rotate the regulator adjustment knob in, towards
the regulator body.
Disassembly, assembly, and adjustment can be done
without these tools, but the work is much easier and
the adjustment is better if these tools are used. The
above 4 tools are available together along with a tool
case. The “Tool Kit with Pouch” is Part #525-620.
This kit is included with each new Kirby Morgan helmet that is equipped with the SuperFlow
Tool Kit with pouch - Part #525-620.

regulator.
2) Ensure the supply pressure is connected and properly adjusted to 135 to 150 p.s.i.g.
3) Turn on the gas supply.
Set the supply pressure to between 135 and 150 p.s.i. before
The regulator should begin to free flow once the adjustment
knob is screwed out several turns.
4) Rotate the adjustment knob out counterclockwise
slowly, until a slight steady flow develops.
5) Slowly rotate the adjustment knob in clockwise,
until the free flow stops. Lightly depress the purge
button several times and ensure the gas flow has
stopped.
7.8.3 Inspection of SuperFlow
®
Regulator
Body Interior
Tools Required:
1/4 inch Flat Blade Attachment on Torque Screwdriver
1) Remove the demand regulator clamp by removing
the clamp screw.
2) Lift off the regulator cover and diaphragm.
3) Clean the diaphragm with the soapy solution, per
Chapter 6 and wipe dry. Inspect the diaphragm for
holes, tears or any signs of deterioration by holding it
up to a white light and stretching and pulling. Check
for a good bond between the metal disc and the silicone. Replace diaphragm if any doubt exists.
4) Inspect the interior of the demand regulator body
for damage, corrosion and cleanliness. Clean the
interior of the regulator body if necessary.
5) Reinstall the diaphragm, cover, and clamp. Do not
lubricate the diaphragm Tighten the clamp screw to
the recommended torque to 12 inch pounds using a
torque screwdriver.
6) Lightly depress the purge button. There should be
between 1/16” and 1/8” free travel in the button before
gas flow starts. When the button is fully depressed, a
strong surge of gas must be heard.
7) If the purge button travels less than 1/16” or greater
than 1/8” before free flow is heard, the demand regulator requires internal adjustment, per this chapter.
Remove the demand regulator clamp.
Use only replacement diaphragms manufactured by Kirby Morgan. Use of other
diaphragms may degrade performance
and may cause increased breathing resistance. This can lead to fatigue and the
inability to work at full capacity.
NOTE: Older regulator clamps, when properly
torqued, had a gap of approximately 1/32” to
1/16” between the retaining clamp surfaces when
fully tightened. All new clamps when properly
torqued, have little or no gap between the retaining clamp surfaces.
