ELECTRICAL WIRING

Refer to the air compressor's serial label for the unit's voltage and amperage requirements.

Use a dedicated circuit

For best performance and reliable starting, the air compressor must be plugged into a dedicated circuit, as close as possible to the fuse box or circuit breaker. The compressor will use the full capacity of a typical 15 amp household circuit. If any other electrical devices are drawing from the compressor's circuit, the compressor may fail to start. Low voltage or an overloaded circuit can result in sluggish starting that causes the motor overload protection system or circuit breaker to trip, especially in cold conditions.

NOTE: To handle the initial electrical toad of starting the air compressor, a circuit breaker is recommended. If the air compressor is connected to a circuit protected by a fuse, use dual element time delay fuses (Buss Fusetron type "T" only).

EXTENSION CORDS

NOTE: Avoid use of extension cords.

For optimum performance, plug the compressor power cord directly into a grounded walt socket. Do not use an extension cord unless absolutely necessary. Instead, use a longer air hose to reach the area where the air is needed.

If use of an extension cord cannot be avoided, the cord should be no longer than 50 feet and be a minimum wire size of 12 gauge (AWG). Do not use a 16 or 14 gauge extension cord.

Use only a 3-wire extension cord that has a 3-blade grounding plug, and a 3-slot receptacle that wilt accept the plug on the product. Make sure your extension cord is in good condition. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. The smaller the gauge number, the heavier the cord.

GROUNDING INSTRUCTIONS

FOR CORD-CONNECTED MODELS:

This product should 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 ordinance.

IL_Improper installation of the grounding plug can result in a risk of electric shock. If repair or replacement of the cord or plug is necessary, do not connect the grounding wire to either fiat blade terminal of the plug. The wire" insulation having an outer surface that is green with or without yellow stripes is the grounding wire.

This product is for use on a 115 or 230 volt circuit. A cord with a grounding plug, as shown here, shall be used.

Make sure that the product is connected to an outlet having the same configuration as the plug (see Fig. 5). No adapter should be used with this product.

Check with a licensed electrician if the grounding instructions are not completely understood, or if in doubt as to whether the

200-2792

product is properly grounded. Do not modify the plug provided; if it will not fit the outlet, have the proper outlet installed by a licensed electrician.
