Check Valve: When the air compressor is
operating, the check valve is "open", allowing
compressed air to enter the air tank. When the air
compressor reaches "cut-out" pressure, the check
valve "closes", allowing air pressure to remain inside
the air tank.
Pressure Release Valve: The pressure release
valve located on the side of the pressure switch, is
designed to automatically release compressed air
from the compressor head and the outlet tube when
the air compressor reaches "cut-out" pressure or is
shut off. The pressure release valve allows the motor to
restart freely. When the motor stops running, air will be
heard escaping from this valve for a few seconds. No
air should be heard leaking when the motor is running,
or continuous leaking after unit reaches "cut-out"
pressure.

Break-in instructions

Serious damage may result if the following break-in
instructions are not closely followed.

This procedure is required before the air compressor is put into service and
when the check valve or a complete compressor pump has been replaced.

Make sure the On/Auto/Off lever is in
the "OFF" position.

NOTE: If quick connect is installed, pull
coupler back until it clicks to prevent air
from escaping through the quick connect.

Plug the power cord into the correct
branch circuit receptacle. (Refer to
Voltage and Circuit Protection
paragraph in the Installation section of
this manual.)

Open the drain valve fully (counter-clockwise) to permit air to escape and
prevent air pressure build up in the air tank during the break-in period.

NOTE: Always drain tank on a washable surface or in a suitable container to
prevent damaging or staining surfaces.

Move the On/Auto/Off lever to "ON/AUTO" position. The compressor will
start.

Run the compressor for 15 minutes. Make sure the drain valve is open and
there is minimal air pressure build-up in tank.
