PLASTIC DECOMPOSITION PRODUCTS
Seven Major Sub-Assemblies
Two versions exist:
Standard and PR14, both perform the same function
MMR second stage regulator shown in belt holster position. Regulator is Pressure Demand.
Green band on cylinders indicates High Pressure (4500psi)
Yellow bank on cylinders indicates Low Pressure (2216 or 3000psi)
ICM 2000 Series
5. Fasten the waist strap, and pull tight for a snugfit. 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.
1. Loosen the neck straps so the end-tabs are at the buckles.
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.
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.
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
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.
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.
Check the bypass by turning the red knob counter-clockwise until you feel increased airflow. Close the bypass.
1 complete turn is fully open.
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.
Secure in storage position during overhaul or other tasks if still wearing scba.
Push the release buttons on the top & bottom of the regulator and pull the regulator down and out of the facepiece.
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.
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.
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.
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.
To keep moisture from entering the MMR, stow the MMR in the stand by belt mount holder.
Watch for ice build up on the release buttons and bypass valve. Check for proper operation prior to entering a hazardous atmosphere.
When replacing cylinders, be careful to prevent moisture from entering the system. Water can contaminate the system and freeze.
Thoroughly dry the facepiece and MMR after cleaning.
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.
