INSTALLATION INSTRUCTIONS
GROUNDING
This product must be grounded. In the event of an electrical short circuit, grounding
reduces the risk of electric 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. Do not use grounding
adapter.
This product is for use on a nominal 120 volt circuit and has a grounding plug similar
to the plug illustrated in Figure 2. If the listed conditions cannot be met or if nuisance
tripping of the current protection device occurs, it may be possible to operate the
compressor from a 120 volt 20 amp circuit.
Check motor data plate for 240 volt compatibility. A 240 volt unit must be operated on a
240 volt circuit. The cord must only plug into a 240 volt grounded outlet and may require a
new cord and plug. See Figure 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 25 ft. 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 below 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.)
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.
When converting 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.
Check with a qualified electrician or serviceman when the grounding instructions are not completely understood, or when in
doubt as to whether the product is properly grounded. Do not modify the plug provided; if it does not fit the outlet, have the
proper outlet installed by a qualified electrician. Only connect the product to an outlet having the same configuration as the plug.
Do not use an adapter with this product.
The 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 is 120 volts.
3. Circuit is equipped with a 15 amp circuit breaker or a 15 amp slow blow fuse type T (for Canada use Type D).
4. The length of copper wire between the outlet and circuit breaker is not longer than 40 feet of 14 AWG or 70 feet of 12 AWG.
