3. Preliminary Testing
(1) Preliminary testing of the regulator is necessary to identify any problems with the first and second
stages and verify overall regulator function. This testing will include:
1. Visual inspection of the regulator
2. Inspection of the hoses
3. Cracking effort and negative pressure test
Visual inspection is done to identify issues that could affect servicing and to ensure that pressurizing
the system will not compromise the safety of the service technician.
Check all connections to make sure they are secure.
Check that on the first stage, there are no extruded O-rings, and hoses are tight.
Detailed inspection of hoses is done to ensure it is safe to pressurize the regulator set. Look for
evidence that might lead to hose failure. Check all hose connection crimps. Defects must be taken care
of before pressurizing the system! Replacement of any suspect hoses is recommended.
Caution Note: Defects in hoses require replacement before pressurizing the
regulator! Failure to do so may result in serious injury!
(2) The Intermediate Pressure (IP) of the first stage should be confirmed before testing the second
stage.
(3) The standard operating range for the system is with an IP of 135 psi.
