PRESSURE VESSELS

Air receiver tanks and other pressure containing vessels 
must be equipped with a properly sized pressure relief 
valve, pressure gauge, and a tank drain. The drain valve 
must be located in the bottom of the air tank(s) to provide 
for moisture removal.

TANK PRESSURE GAUGE

The tank pressure gauge indicates the pressure of the air 
in the tank.

FEATURES

When using the compressor for spray painting, isolate the 
compressor as far away from the work area as practical, 
employing extra air hose rather than an extension cord.
Warranty will be void if a failure is determined to be caused 
by dust, dirt or other contaminants.

COMPRESSED AIR DISCHARGE SYSTEM

   WARNING!

Discharge piping can exceed 350°F when compressor 
is operating. Do not use plastic pipe or lead tin soldered 
joints for a discharge line. Do not modify the discharge 
line.

   WARNING!

Pressure vessels must not be modified, welded on, or 
repaired. Such actions may cause property damage, 
severe injury, or even death.

INSTALLATION

Air compressors should be located in an area that is dry, 
clean, well lighted, and adequately ventilated.

Air supplied to the inlet filter must be clean. The compressor 
belt guard must not be located closer than 12 inches to a 
wall, or 24 inches to another compressor. Additional safety 
can be achieved by locating the pulley drive system, with 
the guard, next to the wall.
The compressor may only be operated in temperatures 
under 104°F and over 32°F. In cold climates, the compressor 
should be installed in a heated building.
Proper mounting of the compressor unit is crucial to the safe 
operation and longevity of the equipment. The installation 
requires a stable, flat and level surface. Satisfactory results 
can usually be obtained by mounting the compressor 
unit on rubber feet supplied with the unit. Refer to 

Fig. 2

Uneven feet drawn tightly to a concrete floor or truck bed 
will cause severe vibrations resulting in cracked welds or 
fatigue failure. 

If the unit is mounted to a concrete floor 

or truck bed or similar foundation, loosen the lock nut 
several turns & lock it with a back-up nut!
