LEAK TESTING
Checking for leaks and proper operation
1. Follow the User's Instructions supplied with the Air Masks to connect the alarm to a fully-
charged cylinder.
2. Check that the bypass is closed.
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. If the gauge needle drops more than
100 psi. in 10 seconds, check the Quick-Fill components for leaks using leak-detection
solution. Correct any leaks before using this apparatus.
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.
