reaches cut-out pressure, the check valve closes, allowing air 

pressure to remain inside the air tank.
AIR INTAKE FILTER 
The filter (A) is designed to clean air entering the 

A

pump. To ensure the pump continually receives a 

clean, cool, and dry air supply the filter must always 

be clean and the filter intake must be free from 

obstructions.
AIR TANK DRAIN VALVE
The drain valve (H) is located at the base of

 

the air tank and is used to drain 

condensation at the end of each use. See 

Draining Air Tank under Maintenance.

TANK PRESSURE GAUGE
The tank pressure gauge (C) indicates the reserve air 

C

pressure in the tank.

GLOBE VALVE/AIR DISCHARGE VALVE:  (sold 

separately, not shown) 
Opens and closes air distribution from compressor. See 

Distribution System paragraph under Installation.
REGULATOR (sold separately, not shown): 
An air pressure regulator or a separate air transformer which 

combines the functions of air regulation and/or moisture and 

dirt removal is recommended for most  applications. See 

Distribution System paragraph under Installation. 
AIR COMPRESSOR PUMP
The pump 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.
MOTOR OVERLOAD PROTECTOR
The motor has a thermal overload protector. 

J

overload protector will shut off the motor. The 

motor must be allowed to cool down before

INSTALLATION
Assembly (Fig. 1)

Unpack the air compressor. Inspect the unit for damage. If the 

unit has been damaged in transit, contact the carrier and 

complete a damage claim. Do this immediately because there are 

time limitations to damage claims. 
 

The carton should contain:

 

•

 

air compressor

 

•

 

operator and parts manuals

Check the compressor’s serial label to ensure that you have 

received the model ordered, and that it has the required pressure 

rating for its intended use.
