2.Place the (4) washers (supplied) between the floor and air compressor feet. If needed, solid shims may be placed between the washers and floor to evenly distribute weight on all four feet. See next figure.

3.Place the (4) 3/8" lag screws through the air compressor feet, washers, shims, and into the anchors.

4.Torque 3/8" lag screws to 7-10 ft.-lbs.

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.
