After repairs are completed and air lines are 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
a large volume of air, followed by a slow flow of air lasting approximately
thirty seconds. Check for leakage at these locations to insure the
PURest Air Dryer operates properly.
