EXO Full-Face Mask Manual

WARNING

This mask 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 mask prior to diving.

The EXO comes from the factory lubricated for oxygen service. If the exo is to be used for enriched air or oxygen use it must be carefully maintained and cleaned in accordance with this manual. components requiring Lubrication must be only be lubricated with an oxygen compatible lubricant such as Christo Lube or Krytox. Any breathing mixture containing an oxygen content greater than 23% oxygen is considered enriched gas.

All Kirby Morgan helmets, masks, and low pressure demand regulators must not be used with oxygen mixtures in excess of 50% oxygen by volume without ﬁrst ensuring all low pressure (less than 225 psig, 15.5 bar) gas transporting components have been cleaned for oxygen service. Only oxygen compatible lubricants such as Krytox™ and ChristoLube™ should be used on components requiring lubrication and lubricants should be used sparingly. Never mix different types of oxygen compatible lubricants. Helmets or masks used primarily for air diving and occasionally for enriched gas use should be cleaned at more frequent intervals than helmets used for mixed gas diving only.

KMDSI regards the use of any breathing gas mixture greater than 50% oxygen to be treated as oxygen. This belief is in keeping with the recommendations set forth by the National Fire Protection Association (NFPA), Compressed Gas Association (CGA), and the American Society for Testing and Materials (ASTM).

Kirby Morgan “High Pressure Components” (greater than 225 p.s.i.g., 15.5 bar) must not to be used with pure oxygen, Nitrox, or any breathing gas mixtures with oxygen content greater than 23.5 % by volume. Using oxygen mixtures in excess of 23.5 % by volume may lead to a ﬁre or explosion, which could result in serious injury or death.

Any diving helmet, full face mask, regulator, control console or breathing life support item manufactured or sold by KMDSI must not be used with breathing gas mixtures in excess of 50% oxygen without ﬁrst ensuring that all gas transporting components have been cleaned for oxygen service, have oxygen compatible soft goods lubricated with an approved oxygen compatible lubricant such as Krytox or Christo Lube grease.

The Kirby Morgan SuperFlow 1st stage scuba regulator, as well as all Kirby Morgan dive control consoles and highpressure gas components (greater than 225 p.s.i.g., 15.5 bar) should not be used with pure oxygen, Nitrox, or any breathing gas containing more than 23.5 % oxygen by volume. The ﬁrst stage is not intended for use with enriched gas mixtures.

General Information Regarding 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.

Bev Morgan, Chairman of the Board

Kirby Morgan Dive Systems, Inc.

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 give 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, 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.

The SuperLite-17B was ﬁrst developed in 1975 and quickly set a 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.

The SL-17B 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 his 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 breathing system parts with all Kirby Morgan helmets and masks. The breathing system has been man-tested to 1600 FSW and approved by the U.S. Navy for surfacesupplied 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 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 100 PSI - 230 PSI.

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.

The mask may also be used surface supplied. We are currently developing several different pod conﬁgurations for both open circuit and rebreather use. For further information, see

KMACS-5

w/ Communications

The K irb y Morg an Ai r Con trol Syst em- 5 (KMACS-5) 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 to be used. Low-pressure air supply ﬁttings allow for a compressor to be used as the primary air source.

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.

Operating Instructions

2.1 Introduction

This section provides the manufacturer’s recommendations on how to use the three EXO Full-face Masks. The use of these diving masks will vary with the type of diving and environmental conditions. A proper training program in the use of full-faced masks must be undertaken prior to diving the mask.

Practice using the mask in a calm, clear body of water (pool) before open water diving. There is a video available from Team Visions that goes over many of these basic procedures. The video, Diving With The EXO-26 Full-face Mask is available from Best Publishing PO Box 30100 Flagstaff Ariz. 86004 Ph 800 468-1055.

2.2 First Use and Pre-Dive Set-Up

When you ﬁrst receive your EXO Full-face Mask, 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! Read all warning labels & caution tags.

Be sure to complete the enclosed warranty card and return to KMDSI as soon as possible. Warranty claims require that a card be on ﬁle at KMDSI 10 days after purchase. Incomplete warranty cards are considered invalid.

2.4 Visual Inspection

Visually inspect the entire exterior and interior of the mask.

- The face seal should be in good condition with no cracks, tears, or punctures.

- The spider (head harness) should be intact. Stretch the spider and inspect it carefully for signs of cracking or tearing.

- Inspect the face port. It should be clean and clear. Anti fog solutions should be applied prior to use.

-Check the wiring for the communications, if present. Make sure the communication module mount nut is screwed down tight.

-In the EXO Original, inspect the air inlet tube and make sure it is properly seated on the regulator.

-In the EXO Standard or BR, inspect the oral nasal and equalizer and make sure they are securely mounted. If the mask does not have communications installed, be sure to use a microphone hole plug (320-001) in the oral nasal.

-Check the regulator assembly to ensure that it is secured tightly on the mask frame.

2.3 Pre Dress-in Procedure

Before dressing in for a dive, an inspection of the mask and all related gear should be made to ensure everything is in proper working order. This should be done well in advance of the dive, so any problems or adjustments can be dealt with. Read and understand this manual before you dive. Chapter 2 tells you the basic operat- ing procedures and how to perform the pre-dive mask inspections and pre-dive regulator function tests.

-Check the regulator cover to ensure that it is tight on the regulator body.

-With no air to the mask, screw the regulator adjustment knob all the way out and back in to ensure that it turns freely.

2.5 Clean Face Port

Remove any sand or debris from the interior of the mask and face port which may be inhaled or blown into the divers face, interfering with the diver's vision.

Under certain conditions, depending upon water temperature, you may ﬁnd it necessary to prep the mask lens to keep it from fogging while diving. There are a number of commercial defoggers available for scuba diving which work well. Follow the directions on the label for use.

If no commercial preparation is available it is possible to use soap. Use a small amount of liquid soap on a rag and smear a thin ﬁlm on the inside of the lens. Do not rinse this ﬁlm off. Apply the soap just prior to entering the water.

2.6 Adjusting the Equalizer EXO Standard or BR

There are different height positions that the equalizer can be adjusted to. Carefully peel the equalizer out of the wire retainer and reposition it in another one of the molded grooves in the equalizer. The wire retainer can also be slightly bent in one direction or another, up or down, to get the angle of the equalizer just right. Ensure that the corners of the equalizer grooves are "snapped" into position on the wire retainer so that it does not come loose.

EXO Full-Face Mask Manual

The equalizing device can be adjusted to the precise height and position that you need.

WARNING

CAUTION

2.7 Checking Regulator Functions & Preparing the EXO for Use In SCUBA Mode.

Attach the low-pressure hose that is supplied with the mask to the low-pressure (L.P.) port on your 1st stage regulator and then to the mask. Never connect the hose or mask to a high pressure (H.P.) port. When attaching the hose to the regulator ALWAYS USE A BACK UP WRENCH ON THE NIPPLE TUBE.

The included angle swivel provides more comfort with at a variety of head positions. KMDSI recommends always using this attachment.

Prior to attaching your ﬁrst stage regulator to your tank be sure the regulator adjustment knob on the mask is screwed all the way in. This will prevent the regulator from free ﬂowing when the air is turned on.

If you are not using the inlet angle ﬁtting, a backup wrench must be used on the hex ﬁtting of the regulator when tightening. Otherwise the regulator may come out of adjustment!

A submersible pressure gauge is considered essential for full-face mask scuba diving. The diver must plan his dive to avoid running out of air while wearing a full-face mask. There is no way to safely buddy breathe underwater, use an octopus rig, or snorkel on the surface while wearing a the EXO full-face mask. If the submersible pressure gauge should fail during the course of a dive, the dive should be terminated immediately.

Your 1st stage regulator should be equipped with a submersible pressure gauge. Attach the ﬁrst stage to your tank and turn the air on while holding the submersible pressure gauge away from you. Once the air is on, check the pressure gauge to ensure you have a full tank.

To check the EXO-standard and BR regulators for proper function and adjustment, ﬁrst ensure the demand regulator adjustment knob is in fully clockwise then bring up a gas supply at between 135-150 psig. Slowly back out on the adjustment knob counterclockwise until a slight free ﬂow develops then adjust in until the free ﬂow just stops.

Always use a back-up wrench when attaching or removing a hose to the regulator. Note the angle swivel in use.

At this point lightly depress the purge button, the button should only travel between 1/16th to 1/8” before a ﬂow is started. If the button travels less than 1/16” or greater than 1/8” before ﬂow starts the regulator will need to be adjusted (see chapter 6)

Higher ﬁrst stage regulator pressures may cause free ﬂow, but turning the regulator adjustment knob in should stop the ﬂow. In the unlikely event there is still ﬂow, proceed to the regulator adjustment section in Chapter 6 to reset the regulator.

EXO Full-Face Mask Manual

WARNING

2.8 Test the Regulator

Loosen all the straps on the spider and hold the mask on your face. Take a couple of good breaths, breathing slow and soft at ﬁrst then hard and fast. The regulator should be operating with the minimal amount of breathing resistance and no free ﬂowing.

Any type of an air ﬂow "hiss" should be able to be adjusted out by using the adjustment knob. If the adjustment knob is adjusted all the way in and the regulator still hisses, see the regulator adjustment section, Chapter 6.

Pressing the purge button should cause a fairly strong air ﬂow into the mask. If there is no ﬂow when pressing the purge button, or if breathing is difﬁcult, see the regulator adjustment section in Chapter 6.

Once you enter the water, the regulator can be adjusted for a variety of diving conditions and positions just by turning the adjustment knob in or out.

2.9 Wireless Communications

There are several manufacturers that produce a wireless communications unit that can be used with the EXO Mask. If you are using wireless communications read and follow all of the manufacturer’s instructions for your particular unit.

If you are using wireless communications you should test the communications by placing the transducers from both send and receive units in a bucket of water and speaking into the mask. Communications should always be tested prior to the diver entering the water.

Your wireless system must not be attached to your weight belt.

Always test the function of your regulator prior to entering the water.

The waterproof case for your wireless communications unit should only be attached to your scuba backpack, NEVER to your weight belt. In the event your belt must be dropped the belt must have a clear drop path and must not be connected to any other piece of gear. If this procedure is not followed the weight belt and wireless electronics case will be attached to the mask by the connecting wire. This could cause the mask to ﬂood, leading to drowning.

EXO Full-Face Mask Manual

WARNING

2.10 Using the EXO in the SurfaceSupplied Mode

If you have not been trained in the proper use of surfacesupplied diving equipment we strongly recommend that you complete a training course in the use of this equipment prior to diving in the surface-supplied mode.

Read and understand the Checking Regulator Function and Preparing The EXO for use in scuba mode section of this chapter. The basic connecting instructions of the mask and regulator function tests are the same.

The one way valve is a very important component. It prevents the ﬂow of air out of the mask in the event of a sudden lowering of pressure in the umbilical supply hose due to an accidental break in the hose or ﬁtting. Not only would the emergency air be lost if the one way valve failed (concurrent with a hose or ﬁtting break) but the diver could be “squeezed”, a very serious accident. Do not dive in the surface-supplied mode without a one-way valve.

At a minimum, if the EXO is to be used for surfacesupplied diving the following systems and components must be in place and in proper working condition:

1) Air Supply: Either a low-pressure compressor or high pressure air bottles. (See operating speciﬁcations)

2) Dive Control System: An air management box to control the ﬂow of air delivered to the diver or divers (like the KMACS-5 - Kirby Morgan Air Control System - offered by KMDSI).

3) Diver's Umbilical: Hose bundle consisting of air supply hose, pneumofathometer hose (depth sensing), communications wire and rope as a strength member.

4) Diver's Manifold Block: A metal block that has a one way valve that the umbilical attaches to, an emergency valve that the bail out system attaches to and L.P. ports for attaching the mask hose, dry suit inﬂators and other accessories.

The EX0-BR works well in the surface-supplied mode.

Emergency Valve

Accessory Ports

One Way Valve

KMDSI Manifold Block Assembly

The EXO Mask is not equipped with a one way valve (non-return valve) as supplied from the factory. For surface-supplied diving, the diver must use a manifold block equipped with a one way valve. Do not connect the diver's umbilical directly to the EXO without a one-way (non-return) valve. In the event of a rupture of the hose, this can lead to a squeeze, a potentially fatal accident.

WARNING

Never dive if the one-way valve is not op-

erating properly. If the hose or breathing gas/air ﬁtting 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.

The one-way valve must be tested daily, prior to commencement of diving operations. Failure of the one-way valve could cause serious injury or death.

If the one-way valve or the adapter is loosened this will allow breathing gas to leak out of the breathing system. This could also result in a loss of all pressure to the mask, leaving the diver with nothing to breathe.

EXO Full-Face Mask Manual

2.11 Testing the Manifold Block

Prior to assembling a bail-out system, the one way valve and emergency valve should be tested for proper function. Equipment Needed:

-Manifold Block

-Bail-out bottle

-1st Stage regulator w/octopus and scuba reg hose attached

-KMACS-5 system with an umbilical supply hose

-Bucket of water

2.11.1 Testing the One-Way Valve

1) With all the accessory holes plugged on the manifold block, attach the SCUBA type regulator hose from a ﬁrst stage regulator that also has an octopus attached, to the emergency valve on the manifold block assembly. The octopus will be used for depressurization once the test is concluded.

2) Connect the ﬁrst stage to the bail-out bottle, open the emergency valve all the way, and pressurize the system.

5) Bail-out System: Consisting of a harness, bail out bottle, ﬁrst stage regulator with over pressure relief valve. This system connects to the emergency valve on the divers manifold block assembly by a hose.

6) Communications System: Provides hard wire communication between diver and topside.

3) Place the pressurized manifold block in a bucket of water and check the one way valve for leaks. No air should leak through the one way valve or from anywhere else on the manifold block assembly. If there is a leak, the one way valve MUST be rebuilt or replaced.

4) As a secondary test, close the emergency valve trapping pressure inside the manifold block assembly and relieve the pressure on the ﬁrst stage using the octopus. Disconnect the hose from the emergency valve.

5) Quickly open the emergency valve by turning the knob. You should hear the trapped air escaping through the emergency valve.

2.11.2 Testing the Emergency Valve

1) With all the accessory holes plugged on the manifold block, attach the umbilical hose to the one way valve.

2) Make sure that the emergency valve is closed all the way and pressurize the umbilical.

3) Place the pressurized manifold block in a bucket of water and check the emergency valve for leaks. NO air should leak through the emergency valve or from

EXO Full-Face Mask Manual

anywhere else on the emergency valve assembly or manifold block assembly. If there is a leak, the emergency valve MUST be rebuilt or replaced.

4) Turn the umbilical off and open the emergency valve to depressurize the system and disconnect the hose.

2.12 Diver’s Harness

The harness provides an attachment point for the manifold block, tools the diver may use while in the water, and the "D" ring where the umbilical shackle connects. The umbilical shackle must connect to the strength member of the umbilical.

2.13 Installing the Manifold Block on the Diver’s Harness

The manifold block assembly is designed to be worn on the diver’s harness. Most divers prefer to attach the manifold block to the right side of the diver’s harness. The shackle which attaches the umbilical to the harness “D” ring, is usually located on the left side. After attaching the umbilical to the “D” ring on the left side of the harness, the umbilical is normally routed behind the diver’s back to the manifold block.

To attach the manifold to the diver’s harness:

The manifold block attaches to the harness and the harness is the primary attachment point for the diver’s umbilical using a snap shackle. Arrange the umbilical so it attaches to the harness, then to the manifold block on the harness. This helps eliminate the possibility of a direct pull on the diver’s mask by top-side.

The harness may also be used to lift an unconscious diver from the water and should be of sturdy construction. It should be equipped with a jock/crotch strap for lifting purposes.

1) Remove one of the screws which holds the mounting plate on the manifold block body and loosen the other screw to provide enough clearance for a harness strap.

2) Swing the plate to one side and position the manifold block on the harness.

3) Swing the plate back into the correct mounting position and thread the screw through the plate and into the manifold body.

4) Tighten both screws until the harness is compressed between the manifold and mounting plate holding the manifold block assembly in place.

Mounting plate

A well designed diver's harness must be rugged. This harness can be equipped with a crotch strap, or “jock.”

EXO Full-Face Mask Manual

WARNING

2.14 Bail-Out Bottle (Emergency Air Supply)

The diver should always dive with a bail-out bottle when diving with surface-supplied air, no matter how experienced the diver or how shallow the water depth. Should the diver become unexpectedly entangled underwater, or if the top side air supply fails, the bail-out bottle may provide the few extra minutes of air the diver needs to deal with the emergency and get to a safe place.

The size of the bail-out bottle should be determined by the water depth, the penetration distance, or the probability of entanglement of the diver. Deeper dives, or distant penetrations can be made with greater conﬁdence with larger bail-out bottles. Dives which require the use of a larger bail-out bottle include, but are not limited to, deep dives and penetration dives.

2.15 First Stage Regulator

The ﬁrst stage regulator used on the bail-out bottle should be a high-ﬂow unit. A submersible pressure gauge must be connected to the regulator to enable the diver to monitor the status of his bail-out supply.

The diver should always be equipped with a bail-out bottle.

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.

Use a high-quality ﬁrst stage for your bail-out system.

The bail-out system must have a submersible pressure gauge for the diver to monitor the gas supply.

EXO Full-Face Mask Manual

CAUTION

WARNING

A standard Scuba submersible pressure gauge must be connected to the high pressure port on the ﬁrst stage so that the diver can monitor his emergency supply.

2.16 Over-Pressure Relief Valve

When using the EXO, the ﬁrst stage regulator should be ﬁtted with an overpressure relief valve. This valve is included with the EXO-BR and must be installed in a low-pressure port on the ﬁrst stage regulator. It is also highly recommended that the valve be used with the EXO Original and EXO Standard, as well as any surface-supplied diving system, anytime a bail-out system is used.

The purpose of this valve is to allow the regulator to bleed off excess pressure should the ﬁrst stage develop an internal leak. If the ﬁrst stage leaks and this valve is not present, the pressure between the regulator and the emergency valve on the manifold block could increase until the hose ruptures. This will cause a complete loss of the bail-out supply. It could also lead to injury of the diver due to the whipping action of the hose.

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.

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 any Kirby Morgan fullface mask or helmet cannot prevent this type of injury.

Order KMDSI Part # 200-017, High Flow Overpressure Relief Valve.

An over-pressure relief valve like this needs to be mounted on the ﬁrst stage of the regulator used for bail-out. It must only be connected to a low-pressure port.

The ﬁrst stage regulator must be equipped with an overpressure relief valve when using the EXO-BR. In the event the ﬁrst stage leaks there is no way for the pressure in the hose attached to the emergency valve on the manifold block assembly to relieve itself. The hose may rupture if this occurs leading to a loss of bail-out supply and possible personal injury to the diver.

2.17 Conﬁguring Your Emergency Gas 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 manifold block closed. This is the only method that we recommend. The advantages of this method are as follows:

EXO Full-Face Mask Manual

WARNING

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. We cannot make this choice for you.

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 ﬁrst 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 manifold block. The manifold block is not designed for high pressure and may burst. This may result in severe personal injury or death.
