2. Check that the MMR bypass is closed and the shut-off button is IN.
WARNING!
Do not try to connect a high-pressure (4500 psig) cylinder to a low-pressure apparatus.
Even though the coupling nut will not thread all the way on the cylinder valve, and bleed
holes in the cylinder valve will let the air escape and not enter the system, this is a
dangerous condition. Failure to follow this precaution can result in serious personal injury
or death.
3. Open the cylinder valve fully. The remote gauge should indicate the pressure in the cylinder.
4. Close the cylinder valve and watch the remote gauge. There should be no drop in pressure if
the apparatus is leak-tight. If the gauge needle moves, check the components for leaks using
leak-detection solution, following the Leak procedures in the SCBA Maintenance Manual.
Correct any leaks before proceeding.
5. Be sure the cylinder valve is fully closed. Open the bypass valve to relieve all pressure from
the system.
6. After all pressure is relieved from the system, close the bypass valve completely.
7. The Air Mask is now ready for service.
8. Read and be sure that you fully understand the instructions for operating the NightFighter
System before use. These instructions are located in the NightFighter System Instruction
Manual P/N 10035580.
