Voltage and Circuit Protection
Refer to the Specifications for the voltage and circuit protection requirements of your air compressor. Use only a fuse or circuit breaker that is the same rating as the branch circuit on which the air compressor is operated. If the air compressor is connected to a circuit protected by fuses, use only dual element time delay fuses, as noted in the Specifications.
This product should be connected to a grounded, metallic, permanent wiring system, or an
Typical schematic subject to all changes as dictated by local electrical codes and authorities.

GROUNDING INSTRUCTIONS
RISK OF ELECTRICAL SHOCK! In the event of a short circuit, grounding reduces the risk of shock by providing an escape wire for the electric
current. This air compressor must be properly grounded.
Improper grounding can result in electrical shock! All grounding should be performed by a licensed electrician in
accordance with national and local electrical codes!
Make certain that the electrical circuit to which the air compressor is connected provides proper electrical grounding, correct voltage and adequate fuse protection. The air compressor can be grounded by the following method:
When hard wiring an air compressor, use wiring that contains a bare copper grounding wire. This wire must be connected to the pressure switch at the grounding location provided. This is located inside the pressure switch. The other end of the wire must be connected to a ground at the fuse/circuit breaker box in accordance with national and local electrical codes.
If these grounding instructions are not completely understood, or if you are in doubt as to whether the air compressor is properly grounded, have the installation checked by an Authorized Warranty Service Center or a licensed electrician.
Lubrication and Oil
Air compressors are shipped without oil. A small
amount of oil may be present in the pump upon receipt of the air compressor. This is due to plant testing and does not mean that the pump contains the correct amount of oil. Do not attempt to operate in order to check wiring or for any reason without first adding oil to the crankcase. Serious damage to the pump can result from even very limited use without oil. Fill crankcase with recommended oil before operating.
