General Electrical Connections
WARNING: Risk of electric shock. Use GFCI. Use indoors only. Disconnect all connections before
servicing. Use identical replacement parts. Servicing must be performed by a licensed, qualified
electrician.
In the event of a malfunction or breakdown, grounding provides a path of least resistance for electrical
current to reduce the risk of electric shock. This compressor is equipped with an electric cord having an
equipment-grounding conductor and a grounding plug, as shown. The plug must be plugged into a
matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.
Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The
conductor with insulation having an outer surface that is green with or without yellow stripes is the
equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not
connect the equipment-grounding conductor to a live terminal.
If the grounding instructions are not completely understood, or if you are in doubt as to whether the
compressor is properly grounded check with a qualified electrician or service personnel.
Grounding Instructions
1. This product is for use on a nominal 120 v circuit.
It 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. Unit is equipped with a cord
that has a grounding prong. It will fit one of the
common outlet types shown in Figure 2. If plug
will not fit in the desired outlet, have the plug
or the outlet replaced by a qualified electrician.
WARNING: Risk of electric shock.
Improper use of grounding
plug can result in a risk of electrical shock. Plug must
be plugged into an outlet that is properly installed and
grounded in accordance with local codes and ordinances
NOTICE: Do not use grounding adapter.
2. Always 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.
3. Use only a 3-wire extension cord that has a 3-blade grounding plug, and a 3-slot receptacle that
accepts the plug on the product. Make sure your extension cord is not damaged. When using an
extension cord, be sure to use one heavy enough to carry the current your product draws. For lengths
less than 25ft. 16-3 AWG extension cords shall be used. An undersized cord results in a drop in the
voltage and loss of power and overheating. (NOTICE: Table 1 shows the correct size to use depending
on cord length. When in doubt, use the next heavier gauge. The smaller the gauge number, the
heavier the cord.)
4. Use of an extension cord may cause excess heat to motor. This could lead to tripped breaker (at
electrical panel) or tripped thermal overload (on compressor motor). If this occurs, eliminate extension
cord and plug compressor directly
into electrical outlet. Avoid using extension cords; use longer air
hose(s) instead.
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.
