REGULAR OPERATIONAL INSPECTION
CONTINUED ON NEXT PAGE...
The Emergency breathing regulator has no end-of-service time indicator and is intended
ONLY for emergency use as part of the RIT-PAK III portable air supply.
Inspect the Emergency breathing regulator as follows:
1. Inspect the breathing regulator for damaged or missing components.
2. Inspect the gasket on the breathing regulator that seals against the facepiece
for rips or damage that may break the seal.
3. Verify that the regulator gasket is properly installed around the outlet port of
the regulator.
4. Verify that the purge valve (red knob) is not damaged and turns smoothly
one-half turn from stop to stop.
5. Inspect the hose for cuts or damage.
6. Inspect the condition of the male quick disconnect for signs of wear. Par-
ticularly look for wear on the locking ridge as shown in FIGURE 15. If the
coating is worn through and bare metal is showing, do not use the regulator
assembly. Remove it from service and tag for replacement.
7. Attach the regulator to the facepiece as follows:
a) Align the two flats of the regulator outlet port with the corresponding flats
in the facepiece port (the red purge valve on the regulator will be in the
12 o’clock position). Insert the regulator into the facepiece port.
b) Rotate the regulator counterclockwise (as viewed from inside of facepiece)
until the red purge valve knob is on the left side of the facepiece. The
lock tab on the regulator will lock into the facepiece retainer with a “click.”
When the lock tab is properly engaged, the regulator will not rotate.
8. Remove the breathing regulator from the facepiece by pulling back on the
regulator retaining latch and rotating the regulator ¼ turn. Inspect the gas-
ket on the breathing regulator again for rips or damage that may break the
seal.
9. Perform the OPERATIONAL TESTING WITH BREATHING REGULATOR AND
FACEPIECE as described in this instruction.
NOTE
AFTER INSPECTION AND TESTING, REFER TO THE PREPARATION FOR USE SEC-
TION OF THIS INSTRUCTION AND CAREFULLY FOLLOW THE INSTRUCTIONS FOR
STORAGE OF EACH OF THE AIR SUPPLY LINES TO ASSURE THAT THEY CAN BE
PROPERLY DEPLOYED WHEN THEY ARE NEEDED.
