Cooling System (not shown): This
compressor contains an advanced
design cooling system. At the heart of
this cooling system is an engineered
fan. It is perfectly normal for this fan
to blow air through the vent holes
in large amounts. You know that the
cooling system is working when air is
being expelled.
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 compres-
sor is operating, the check valve is
"open", allowing compressed air to
enter the air tank. When the air com-
pressor reaches "cut-out" pressure,
the check valve "closes", allowing air
pressure to remain inside the air tank.
Check Valve
Pressure Release Valve: The pres-
sure 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 escap-
ing 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.

How to Stop:

1.

Before Starting

Break-in instructions
damage may result if the follow-
ing 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 com-
plete compressor pump has been
replaced.
1.
NOTE: If quick connect is installed,
pull coupler back until it clicks to
prevent air from escaping through the
quick connect.

Set the On/Auto/Off lever to
"OFF".
Risk of Unsafe
Operation. Serious
Make sure the On/Auto/Off lever
is in the "OFF" position.
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 (coun-
ter-clockwise) to permit air to
escape and prevent air pressure
build up in the air tank during the
break-in period.
Move the On/Auto/Off lever to
"ON/AUTO" position. The com-
pressor will start.
