reconnected, start the engine, build-up pressure to
100 psi, and shut off the engine. Check for air leaks
at the inlet and outlet of the dryer. Correct any
leakage problem. Restart the engine and build-up
pressure to cut-out pressure. At cut-out pressure
the dryer purge valve opens and immediately expels

lasting approximately thirty seconds. Check for
leakage to assure that the PURest Air Dryer will
