DESCRIPTION
The Combination apparatus is a combination pressuredemand, air-line respirator and Escape type self-contained breathing apparatus (SCBA) certified by the
National Institute for Occupational Safety and Health
(NlOSH). NlOSH approval allows the wearer to:
• enter and work in an IDLH atmosphere using an
air-line air source
• work within the area for an extended time using air
from the air-supply hose;
• exit from the area using the air cylinder;
• escape from a dangerous area using the air cylinder.
The air cylinder is not approved for use as an entry device.
Do not use the air cylinder for entry into the work
area. This cylinder is designed for exiting an area or
for escape only. The cylinder capacity is five minutes.
Failure to follow this precaution can result in serious
personal injury or death.
The Combination apparatus consists of the following subassemblies:
• facepiece and breathing tube
• carrier and harness
• pressure demand regulator
• air cylinder and valve
• appropriate section(s) of approved air-supply hose
Facepiece and Breathing Tube
The Combination apparatus is available with either the
Ultra Elite or Ultravue pressure-demand facepieces.
Facepieces materials available are rubber or silicone.
Facepieces are available in small, medium, or large.
The breathing tube carries air from the regulator to the
facepiece. The regulator end of the tube has a plastic nut
and a black plastic insert to guide the coupling nut into
the regulator outlet. The facepiece end of the breathing
tube has a plastic threaded insert to match the facepiece

DESCRIPTION
Ultra Elite Facepiece SpeeD-On™ Facepiece Harness Kit
The following accessories are available for use with the
Ultravue facepiece:
Nosecup Kit is required if the apparatus is used in temperatures below 32 degrees to reduce lens fogging.
The Nosecup Kit is available in three sizes. See the installation instructions.
Spectacle Kit (P/N 454819) includes the support assembly, frame guide, and the spectacle frame. Prescription
lenses can be obtained locally or through MSA. See the
installation instructions.
SpeeD-On Facepiece Harness Kit may be used in place of
the standard rubber headstrap harness on the Ultravue
facepiece. The harness is made of flame and heat resistant (FHR).
Carrier and Harness Assembly
The carrier consists of a backplate, a cylinder band and
latch assembly to hold the cylinder, and a harness assembly, consisting of shoulder strap, and a waist-strap.
Pressure-Demand Regulator
A hose delivers air from the first stage regulator to the
belt-mounted pressure-demand regulator. This regulator
follows the user’s demand for air. Air from the first stage
provides a uniform pressure to the pressure demand regulator admission valve. The admission valve “senses” the
user’s respiration and opens and closes accordingly to
supply breathable air at the user’s flow rate.
First-Stage Regulator
A first-stage regulator reduces cylinder pressure to pressure suitable for the pressure demand regulator. This regulator mounts to the cylinder at the coupling air nut.
Air Cylinder and Valve
The air cylinder consists of a tank (or bottle) and a cylinder valve. The cylinder valve includes a valve body, valve
inlet tube, safety valve (burst disc), and pressure gauge.
The cylinders are intended to be filled to 2216, 2310 and
3000 psig, depending on the label on the cylinder. Service
life is rated at 5-minute service. The pressure gauge continuously shows the air pressure in the cylinder. A handwheel is used to open or close the cylinder valve.
Air-Line (approved air-supply hose)
The Combination apparatus can be used with a wide
range of MSA air-supply hoses, which can be interconnected up to a maximum length of 300 feet. A maximum
of 12 sections of air-supply hose may be used in making
up the maximum working length of hose. The coiled
hoses are considered to be the indicated length, although
the useable lengths are indicated. (Maximum of one section of 8, 15, or 25 ft. of coiled hose or 6 sections of 50 ft.
coiled hoses). MSA also offers an inlet pressure-gauge
assembly that enables a user to check pressure at the
inlet of the MSA air-supply hose, thus assuring that the air
pressure is within the NIOSH approved range. The gauge
is supplied with quick-disconnect fittings to accommodate your particular air-line system.
Note: All air-supply hoses listed below are 3/8” in diameter (hose ID).
The following air-supply hoses from MSA may be used:

DONNING THE APPARATUS
DONNING THE APPARATUS
1. Remove the apparatus from its carrying case or container. Place the facepiece and breathing tube out of
the way to keep them clean.
2. Check the pressure reading on the cylinder gauge.
The gauge should show the pressure listed on the
cylinder label.
3. Don the cylinder, carrier, and harness:
a.Grasp the shoulder
harness and place it
over your head and
on your left shoulder.
b.Fasten the seat-belt type buckle on the waist-strap
and pull the waist-strap tight for a snug fit.
c.Adjust the shoulder harness slide to the desired
position.
4. Don the facepiece:
Do not wear eyeglasses under the facepiece. The temples or sidebars on eye glasses will prevent an airtight seal. if you must wear glasses, install the spectacle kit. Failure to follow this precaution may cause
inhalation of contaminated air, resulting in serious respiratory injury or death.
a.Attach the breathing tube to the facepiece coupling
nut, hand-tighten.
b.Loosen the harness head straps on the facepiece
so the end-tabs are at the buckles.
c.Hold the facepiece
by the straps and put
your chin in first.
d.Then, pull the har-
ness back over your
head.
e.Tighten the lower
(neck) harness
straps first, by
pulling them straight
back, not out.
Tighten the temple
straps the same way.
Tuck in the ends of
the straps so that
they lay flat across
the head.
f. Push the headband pad towards the neck and
repeat step. If necessary, tighten the front strap for
best visibility and fit. Tuck in the ends of the straps
so they lay flat across the head.
5. To Use the SpeeD-On Harness
a.Loosen the neck straps so the end-tabs are at the
buckles.
b.Insert your chin into the facepiece.
c.Pull the harness "net" over the crown of your head.
d.Tighten the neck straps. There are no temple or
front strap adjustments. Tuck in the straps so that
they lay flat across the head.
FACEPIECE FIT CHECK
The Facepiece Fit Check must be performed each time
the facepiece is donned. You must know the face-to-facepiece seal is good before you enter any hazardous area.
To do this:
1. Block off the breathing
tube with either the
palm of your hand, or
by placing your thumb
over the opening inside
the breathing tube coupling nut.
7
TAL 0021 (L) Rev. 5 - 477118
WARNING
DONNING
2. Breathe in and hold
your breath for 10 seconds. If the seal is
good, the facepiece will
collapse and remain
collapsed against your
face.
3. If the facepiece does not remain collapsed, or you
notice any leakage, readjust the straps and test
again. If this does not correct the leak, do not use the
facepiece.
4. Test the exhalation
valve by exhaling. If the
valve is stuck, you will
feel a heavy rush of air
around the facepiece.
You may need a sharp
exhalation at first to
"crack" the valve. If this
does not release the
valve, do not use the
facepiece.
This device may not seal properly with your face if you
have a beard, gross sideburns or similar physical
characteristics. A facepiece that does not seal adequately may allow contaminated air to leak into the
facepiece, reducing or eliminating respiratory protection. If such conditions exist the user assumes all
risks of respiratory injury or death which may result.
The face-to-facepiece seal must be tested before
each use.
FINAL HOOK-UP
1. Turn the air source ON.
2. Connect the air-supply
hose to the regulator
quick-disconnect.
Listen for the “click” as
the quick-disconnect
snaps in place.
Pull on the hose to be sure it is attached securely. Air
should flow immediately from the regulator outlet.
Check that the air-line operating pressure is within the
NIOSH approved range of 65-85 psig.
3. Connect the breathing tube to the regulator. Air should
flow through the pressure demand regulator, through
the breathing tube and into the facepiece. You should
be able to breathe normally. Pull firmly on the breathing tube to be sure the regulator connection is secure.
The regulator should follow your breathing pattern and
supply air only during inhalation.
4. If the unit checks out, you are ready to enter the work
area connected to the air source. Remember, you
must make these tests every time before you enter the
hazardous atmosphere. If the unit fails to meet any of
the tests, the condition(s) must be corrected before
using the apparatus.
EXIT OPERATION
Return to an area which does not require respiratory protection before removing the respirator. The Hip-Air respirator may be used as an escape device when you want to
leave the work area without using the air-supply hose.
Remain connected to the air-supply hose until you are
ready to return to an area which does not require respiratory protection. This cylinder is designed for exiting an area or for escape only. The cylinder capacity is
five minutes. Failure to follow this precaution can
result in serious personal injury or death.
1. Open the cylinder valve fully.
2. Disconnect the air-supply hose at the regulator quickdisconnect. Air flow from the cylinder will start immediately.
Contaminants can enter an air-line respirator system
when air-supply hoses are disconnected and/ or
reconnected in a contaminated atmosphere. The user
must determine the potential risk and take the necessary precautions, which may require that NO disconnection or reconnection of air-supply hoses is permitted in a contaminated atmosphere. If in doubt, DO
NOT disconnect and/or reconnect. Failure to follow
this precaution may result in serious personal injury or
death.
3. Return immediately to an area which does not require
respiratory protection.
