DONNING
The Air-Pack
Warning!
• The model used for this
piece is extremely good
looking and intelligent.
DONNING
1. Remove Facepiece
from pouch
2. Check cylinder
pressure. Min 4000
3. Reach inside right
shoulder straps,
grasp the redundant
alarm and pressure
gauge, slide left arm
through the Left
shoulder straps
4. Bend over slightly,
attach chest strap
5. Fasten the waist strap, and pull tight for a
snug fit. The weight is designed to be carried
on the waist, not the shoulders.
6. As you
straighten, pull the
strap tabs out and
adjust for a
comfortable fit.
7. The shoulder and
waist strap ends
must be tucked in
and lay flat across
the body.
DONNING the FACEPIECE
1.
Loosen the neck straps so
the end-tabs are at the
buckles.
DONNING the FACEPIECE
2. Insert your chin into
the facepiece.
Note: harness may
take a “memory” if
stored over mask.
3. Pull the harness
“net” over the crown of
your head.
4. Tighten the neck
straps; if necessary
tighten the temple
strap adjustments.
Tuck in the straps so
they lay flat across the
head.
Facepiece fit check
First, check the
inhalation valve. Inhale.
If you do not receive
sufficient flow of air, do
not use the facepiece.
The facepiece must be
repaired or replaced.
Facepiece fit check
To check for facepiece fit,
hold your hand over the
inlet and inhale. Hold your
breath at least 10 seconds.
The facepiece should
collapse and stay collapsed
against your face. If it does
not, readjust the facepiece
and test again. If this does
not correct the leak, do not
use the facepiece.
Test the exhalation valve,
take a deep breath and
hold it. Block the inlet
with the palm of your
hand and exhale. If the
exhalation valve is stuck,
you may feel a heavy rush
of air around the
facepiece. You may need
to exhale sharply to open
the valve if this does not
release the valve, do not
use the facepiece
Don Hood and Helmet
Open the Cylinder Valve fully
If air is flowing, push in
the slide button on the
MMR to stop air flow
Listen for any sound of
hissing or popping from
the Audi-larm Alarm or
quick fill valves. If heard,
place out of service.
As the pressure rises
from 50 to 200 psig,
both visible and audible
alarms activate
automatically,
indicating that the
alarms are functional.
When the system is
fully pressurized, the
alarms enter the
Monitor(normal) mode.
Warning
If the Audi-larm fails to ring, ICM, or
HUD system fails to light and tone,
place the SCBA out of service. All
gauges should be within 225 psig of
each other at 4500 psig. If not, place
the SCBA out of service. Failure to
follow these precautions may result in
serious personal injury or death.
Push the release
buttons to
remove the
MMR from the
standby belt
mount
Installing slide Mask Mounted
Regulator
• Grasp regulator and
orient regulator so
that the red bypass
knob is pointing to
the right and slide
connector is on top.
Installing slide Mask Mounted
Regulator
• Slide regulator onto
rail (fast track) of
facepiece cover.
Slide regulator
down the rail until
regulator stops.
Installing slide Mask Mounted
Regulator
• Insert regulator into
facepiece by pushing
upward.
• Check proper
engagement by pulling
on the regulator to
ensure the regulator is
secure.
Inhale sharply to
start the airflow.
Check the bypass by
turning the red knob
counter-clockwise
until you feel
increased airflow.
Close the bypass.
1 complete turn is
fully open.
Warning
There must be a continuous flow of air
when the bypass knob is opened. If
not place the SCBA out of service.
Failure to follow this precaution may
result in serious personal injury or
death.
MMR in the
standby position on
the mask.
Secure in storage
position during
overhaul or other
tasks if still wearing
scba.
Removing the SCBA
Push the release
buttons on the top &
bottom of the regulator
and pull the regulator
down and out of the
facepiece.
Slide the regulator up
the rail and off of the
mask.
Turn off cylinder.
Open the bypass on
MMR to release
system pressure.
Close the bypass.
When the pressure
falls below 200 psig,
turn the ICM off by
pressing the reset
(yellow) button* twice
quickly.
*Both ICM 2000 series and TX series
units turn off with the yellow/reset
button.
Stow the regulator
with the slide button
at bottom in the
stand-by belt mount
when not in use.
To remove the
facepiece, fully loosen
the harness straps and
pull the facepiece up
and away from your
face.
To remove the carrier
harness, loosen the
waist strap and press
the belt buckle release
button IN.
If connected, disconnect chest strap.
To loosen the shoulder strap, grasp the release
loops. Push them out and away from your
body.
Slip your right arm out of the shoulder pad
first, then remove the harness.
Changing Cylinders
1. Be sure there is no pressure in the system. Disconnect the
Audi-larm coupling nut.
2. Lift and turn the latch wing to loosen the the cylinder clamp.
3. Slide out the empty cylinder and install one that is fully
charged, ensure that the cylinder band latch is in the proper
slot. Make sure lock tab on the carrier is fully engaged In the
cylinder band slot.
4. Slide the new cylinder in the carrier with gauge out, turn
latch wing.Push the latch wing toward the back plate, locking
in place.
5. Ensure the cylinder is secure, to check, attempt to pull
the cylinder down and out, away from carrier.
If the cylinder feels loose, retighten and recheck.
6. Check that the O ring is inside the coupling nut. If the O ring
is damaged it MUST be replaced.
7. Thread the coupling onto the cylinder valve, hand tight.
Cold Weather Operations
To keep moisture from entering
the MMR, stow the MMR in the
stand by belt mount holder.
Cold Weather Operations
Watch for ice build up on the
release buttons and bypass
valve. Check for proper
operation prior to entering a
hazardous atmosphere.
Cold Weather Operations
When replacing cylinders, be
careful to prevent moisture from
entering the system. Water can
contaminate the system and
freeze.
Cold Weather Operations
Thoroughly dry the facepiece
and MMR after cleaning.
Quick Fill System Operation
The Quick Fill system lets MSA airmask users
refill and transfill air cylinders while the SCBA
is worn, without the need to remove the air
cylinder, even IN IDLH atmospheres.
Normal Use
If available, can quickly refill from secondary
compressed air source to 4500 psi.
Emergency Breathing Support System
Transfill from Donor SCBA
Transfill from a Secondary Air Source
Key Points
 Locate transfill adaptor on air source.
 Remove the rubber dust covers from fittings.
 Attach hose to the male fitting by pushing the
female fitting onto the male fitting
until it snaps in place.
 Transfilling begins upon connection.
 Compare gauge readings, disconnect by pulling
back the gray sleeve.
 Immediately reinstall the dust cover.
 Return to service.
Emergency Breathing Support System
Key Points
 Donor SCBA should be @ or greater than 2000 psig +
 Remove the emergency hose from pouch
 Remove dust covers from the hose fittings.
 Remove dust cover from male connection
 Push the female fittings from the hose onto the male
fittings on SCBA until they snap into place.
 Visualize gauges, after 30-60 seconds the pressure
will be equal.
 Disconnect the hose from the SCBA’s, reinstall the dust
cover and return to fresh air.
