CAUTION
Do not hang the air control unit directly off a pump air
motor inlet, which could be damaged by the weight of
the unit and operating stress.
Before installing air line components, blow out the pipe
line to remove debris. Be sure air to the regulator is
clean. Erratic operation or loss of regulation is usually
caused by dirt in the regulator.

Use pipe compound or tape sparingly and only on male
threads. Locate the regulator as close as possible to the
equipment it serves.
Install a main air shutoff valve upstream from the air
controls to isolate them for service.
