UNITS WITH LINE CORDS ONLY
NOTE: 120 volt, 15 amp units can be
operated on a 120 volt 15 amp circuit
under the following conditions:
1. No other electrical appliances or
lights are connected to the same
branch circuit.
2. Voltage supply is normal.
3. Circuit is equipped with a 15 amp
circuit breaker or a 15 amp slow
blow fuse type T (For Canada use
Type D).
If the above conditions cannot be met
or if nuisance tripping of the current
protection device occurs, it may be
necessary to operate the compressor
from a 120 volt 20 amp circuit. Some
models convert to 240 volt operation,
see DUAL VOLTAGE MOTOR.
GROUNDING INSTRUCTIONS
1. This product is for use on a nominal
120 or 240 volt circuit and has a
grounding plug that looks like one of
the plugs illustrated in Fig. 5. Make
sure product is connected to an outlet
having the same configuration as the
plug.This product must be grounded.
In the event of an electric short circuit,
grounding reduces the risk of electrical
shock by providing an escape wire for
the electric current. This product is
equipped with a cord having a
grounding wire with an appropriate
grounding plug. The plug must be
plugged into an outlet that is properly
installed and grounded in accordance
with all local codes and ordinances.
DANGER
!
Improper use of grounding
plug can result in a risk of
electrical shock. Do not use
grounding adapter.

2. If repair or replacement of the cord
or plug is necessary, do not connect
the grounding wire to either flat
blade terminal. The wire with
insulation having an outer surface
that is green with or without yellow
stripes is the grounding wire.
3. Check with a qualified electrician or
serviceman if the grounding instructions
are not completely understood, or if in
doubt as to whether the product is
properly grounded. Do not modify the
plug provided; if it will not fit the outlet,
have the proper outlet installed by a
qualified electrician.
PLUGS AND RECEPTACLES
1. If the plug on the electrical cord of
the unit is unfamiliar to you or will
not fit your particular receptacle,
Figure 5 will help you understand
why by illustrating the different
plugs and the voltages they are to
be used with.
2. Make sure that the product is
connected to an outlet having the
same configuration as the plug.
3. The receptacles must be connected
to circuits rated to carry at least the
voltage and amperages shown.
4. NEVER have a receptacle replaced
with one of a higher amperage
before determining the change can
be made according to all electrical
Ground Pin
codes affecting your particular area.
The installation should be made by

a qualified electrician. If the
products must be reconnected for

use on different types of circuits,
the re-connection should be made
by qualified personnel.

DUAL VOLTAGE MOTORS (SOME
MODELS)
The grounding plug
NOTICE
must be changed to
convert unit for dual voltage.
Dual voltage motors may be connected
for either 120 volts or 240 volts. By
comparing the plug on the cord with
the receptacles shown below, you can
determine for which voltage your
compressor is factory wired. Also check
motor decal to change from low
voltage to high voltage.
All wiring must be
WARNING
!
completed by a
qualified electrician. Disconnect from
power source before changing any
wiring.
When converting
WARNING
!
to an alternate
voltage, be sure the green ground wire
of the cord connects to the ground pin
of the plug and to the metal body of
the pressure switch.
Assembly
ADDITIONAL HARDWARE NEEDED
Purchase hose, regulator and shutoff
valve that has a minimum rating of 150
PSI and exceeds the maximum working
pressure of the compressor.
OIL DRAIN EXTENSION
Some models include an oil drain extension
and cap (found with the owner's manual).
Install the oil drain extension and cap
before adding oil to the pump. _To
avoid oil leaks, it is highly recommended to
apply PTFE thread sealant tape or paste
type sealant to the threads on each end of
the oil drain extension. Screw the cap onto
one end of the extension. Remove the oil
drain plug from the base of the pump and
install the oil drain extension (See Figure 6).
