INSTALLATION AND BREAK-IN PROCEDURES (cont'd)
GROUNDING INSTRUCTION
(cont'd)
If
repairing or replacing cord or plug, the grounding wire must
be kept separate from the current-carrying wires. Never con-
nect the grounding wire to a flat blade plug terminal. The
grounding wire has insulation with an outersurface that
is
green
-
with or without yellow stripes.
If these grounding instructions are not completely understood,
or
if
in doubt asto whetherthecompressor is properly grounded,
have the installation checked by a qualified electrician.

Additional Regulators and Controls
Since the air tank pressure is usually greater than that which is
needed, aseparate regulatorisusuallyemployed tocontrolthe air
pressure ahead of any individual air driven device.
Separate air transformers which combine the function of air
regulation, moisture and dirt removal should be used where
applicable.
NOTE
It
is notuncommon for the airtank to contain some
water from the testing of the tank at the factory.

P r o c e d u r e s
Serious damage may result ifthe following break-
in instructions are not closely followed.
This procedure is required:
1. Before the air compressor is put into service.
2. When the checkvalve is replaced.
3. When a complete compressor pump is replaced.

e.
Set the pressure switch lever to the ''OFF'' position.
Plug the power cord into the correct branch circuit
receptacle.
Turn the drain valve clockwise, opening itfully, to
prevent air pressure build-up in the tank.
Move the pressure switch lever to "OWAUTO".
The compressor will start.
Run the compressor for 15 minutes. Make sure
the drain valve, is open and there is
little tank pressure build-up.
After 15 minutes, close the drain valve by turning
it completely counterclockwise. The air rdceiver
will fill to cut-out pressure and the m o t y will stop.
The compressor is now ready for use.

Daily Start-up Checklist
When you are finished:

1. Before attaching air hose or accessories, make sure the 6. Set the pressure switch lever to "OFF. J.
pressure switch lever is set to "OFF" and the air regulator
or shut-off valve is closed.
Using the air
tool
or accessory, bleed the tank pressure
down to approximately 20 psi.
Drain water from air tank by opening drain valve on bottom
of tank.
2.
Attach hose and accessories. 8. Remove the air tool or accessory.
9.
TOO MUCH AIR PRESSURE CAUSES A HAZARDOUS
RISK OF BURSTING. CHECK THE MANUFACTURER'S
MAXIMUM PRESSURE RATING FOR AIR TOOLS AND
ACCESSORIES. THE REGULATOR OUTLET PRES-
SURE MUST NEVER EXCEED THE MAXIMUM PRES-
SURE RATING.
WATER WILL CONDENSE IN THE AIRTANK.
IF NOT DRAINED, WATER WILL CORRODE
AND WEAKEN THE AIR TANK CAUSING A
RISK OF AIR TANK RUPTURE.
3. Turn the pressure switch lever to "ON/AUTO and allow
tank pressure to build. Motor will stop when tank pressure
reaches "cut-out" pressure.
Open the regulator by turning it clockwise. Adjust the regu-
lator to the correct pressure setting. Your compressor is
ready for use.
Alwaysoperate the aircompressor in well-ventilated areas;
freeof gasoline orothersolventvapors. Do notoperatethe
compressor near the spray area.
NOTE
If drain cockvalve is plugged, release all air
pressure. The valve can then be removed,
cleaned, then reinstalled. 4.
10. After the water has been drained, close the drain cock or
drain valve. The air compressor can now be stored.
