SET-UP AND TESTING THE FIRST STAGE
Note: The R60 regulator has a DIAPHRAGM BALANCE 1st stage. For safety, test the first
stage regulator with at least one second stage installed. The demand valve on the second
stage acts as a relief valve in case of a malfunction.
Install an intermediate pressure test gauge into one of the low-pressure ports of the first
stage, and a functional 2nd stage into another low pressure port. Plug any remaining open
outlet ports with suitable port plugs.
NOTE: The following test determines the regulator's lock-up pressure (the pressure put out by
the first stage during a no flow condition).
Attach the regulator to a tank valve giving a source pressure of between 2700 and 3500
psig (186-232 Bar).
