Check that the flow control valve on the generator is fully open and control the flow
with a valve at the process.
Check operating pressure to assure that it is greater than 80 psig (5.5 barg).
Check the system for leaks.
Loss of Outlet Flow
Check operating pressure to assure that it is greater than 80 psig.
Check setting of flow control valve. Adjust if necessary.
Check the system for leaks.
Purity is Lower
than Specified
Check setting of flow rate.
Check the operating pressure to assure that it has not varied from the original reading.
Check the system for leaks.
Calibrate oxygen analyzer (if needed).
Air Leak Through

Check inlet pressure. It should be greater than 15 psig (1 barg) to seal drain.
Remove tubing from the drain outlet, hold finger over drain opening for a few
seconds to allow pressure to build and drain to seal.
Remove bowl from filter assembly and rinse with water.
If leak persists, replace automatic float drain (P/N 21552).
