Wiring Instructions
_ RISK OF
ELECTRICAL
SHOCK. Improper electrical
grounding can result in electrical
shock. The wiring should be done
by a qualified electrician
A qualified electrician needs to knows
the following before wiring:
1. The amperage rating of the
electrical box should be
adequate. Refer to the
Specification Chart, in the parts
manual, for this information.
2. The supply line should have the
same electrical characteristics
(voltage, cycle, phase) as the
motor. Refer to the motor
nameplate, on side of motor, for
this information.
NOTE: The wiring must be the same
as the motor nameplate voltage plus
or minus 10%. Refer to local codes
for recommended wire sizes, correct
wire size, and maximum wire run;
undersize wire causes high amp draw
and overheating to the motor.
Electrical wiring
must be located
away from hot surfaces such as
manifold assembly, compressor
outlet tubes, heads, or cylinders.
GROUNDING INSTRUCTIONS
This product should be connected to
a metallic, permanent wiring system,
of an equipment-grounding terminal
or lead on the product.
Voltage and Circuit Protection
Refer to the Parts Manual for the
voltage and minimum branch circuit
requirements.
Certain air compressors can be
operated on a 15 amp circuit if the
following conditions are met.
1. Voltage supply through branch
circuit is 15 amps.
2. Circuit is not used to supply any
other electrical needs (lights,
appliances, etc.).
3. Circuit is equipped with a 15
amp circuit breaker or 15 amp
time delay fuse. NOTE: If
compressor is connected to a
circuit protected by fuses, use
only time delay fuses. Time delay
fuses should be marked "D" in
Canada and "T" in the US.
If any of the above conditions cannot
be met, or if operation of the
compressor repeatedly causes
interruption of the power, it may be
necessary to operate it from a 20
amp circuit.
Air Distribution System
Plastic or PVC pipe
is not designed for
use with compressed air.
Regardless of its indicated
pressure rating, plastic pipe can
burst from air pressure. Use only
metal pipe for air distribution lines.
The next figure represents a typical
air distribution system. The following
are tips to remember when setting up
the air compressor's air distribution
system.
11_ENG D29312
Use pipe that is the same size as
the air tank outlet. Piping that is
too small will restrict the flow of
air.
If piping is over 100 feet long,
use the next larger size.
Bury underground lines below
the frost line and avoid pockets
where condensation can gather
and freeze. Apply pressure
before underground lines are
covered to make sure all pipe
joints are free of leaks.
A flexible coupling is
recommended to be installed
between the air discharge outlet
and main air distribution line to
allow for vibration.
A separate regulator is
recommended to control the air
pressure. Air pressure from the
tank is usually to high for
individual air driven tools.

Know Your Air Compressor
READ THIS OWNER'S MANUAL AND SAFETY RULES BEFORE OPERATING
YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with
the location of various controls and adjustments. Save this manual for future
reference.
Description of Operation
Become familiar with these controls
before operating the unit.
Tank
On/Auto/Off Switch: Turn this switch
ON to provide automatic power to the
pressure switch and OFF to remove
power at the end of each use.
Pressure Switch: The pressure
switch automatically starts the motor
when the air tank pressure drops
below the factory set "cut-in"
pressure. It stops the motor when the
air tank pressure reaches the factory
set "cut-out" pressure.
Safety Valve: If the pressure switch
does not shut off the air compressor
at its "cut-out" pressure setting, the
safety valve will protect against high
pressure by "popping out" at its
factory set pressure (slightly higher
than the pressure switch "cut-out"
setting).
Tank Pressure Gauge: The tank
pressure gauge indicates the reserve
air pressure in the tank.
Globe Valve: Opens and closes air
discharge valve. Turn knob counter-
clockwise to open and clockwise to
close.
Drain Valve: The drain valve is
located at the base of the air tank
and is used to drain condensation at
the end of each use.
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.
13_ENG
D29312
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.
How to Use Your Unit
How to Stop:
1. Set the On/Auto/Off lever to
"OFF".
Before Starting
Break-in Procedure
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 continuous
leaking after unit reaches "cut-out"
pressure.
