Wiring Instructions
RISK OF ELECTRICAL SHOCK. Improper electrical grounding can result in electrical shock. The wiring
should be done by a qualified electrician to comply with national and local electrical codes.
A qualified electrician needs to knows the following before wiring:
1.The amperage rating of the electrical box should be adequate. Refer to the product specifications, found in the front of this 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.

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.
