Air Compressor Pump (not shown):
Compresses air into the air tank.
Working air is not available until the
compressor has raised the air tank
pressure above that required at the
air outlet.
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.
Check Valve
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 after the unit reaches "cut-out"
pressure.

Motor Overload Protector: The
motor has an automatic reset
thermal overload protector. If the
motor overheats for any reason, the
overload protector will shut "Off" the
motor. The motor must be allowed
to cool down before restarting. The
compressor will automatically restart
after the motor cools.
How to Use Your Unit
How to Stop:
1. Set the On/Auto/Off lever to
"Off".
Before First Start-up
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.
1. 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.
2. Plug the power cord into the
correct branch circuit receptacle.
(Refer to "Voltage and Circuit
Protection" paragraph in the
Installation section of this
manual.)
3. Open the drain valve fully
(counterclockwise) 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.
