Voltage and Circuit Protection

Refer to your Outfit Parts Manual for the voltage and circuit
protection requirements of your compressor. Use only a fuse
or circuit breaker that is the same rating as the branch circuit
the air compressor is operated on. If the compressor is
connected to a circuit protected by fuses, use only dual
element time delay fuses, as noted in the Parts Manual.
*Some two stage compressors require a magnetic starter.
Check the specification chart in the Outfit Parts Manual to
see if required or not.
Typical schematic subject to all changes as dictated
by local electrical codes and authorities.
This product should be connected to a grounded,
metallic, permanent wiring system, or an equip-
ment-grounding terminal or lead on the product.

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!
INSTALLATION (cont'd)
Make certain that the electrical circuit to which the 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 in 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 in doubt as to whether the compressor is properly grounded,
have the installation checked by an Authorized Warranty Service
Center or a licensed electrician.

Lubrication and Oil

Remove the oil fill plug and fill the crankcase with
recommended oil. Refer to the Service Instructions in this
manual for the specific oil recommended for use in your
compressor unit (See page 14). Replace the oil fill plug.
Additional Regulators and Controls
Since the air tank pressure is usually greater than that which is
needed, a separate regulator is usually employed to control the
air pressure ahead of any individual air driven device.
Separate air transformers that combine the functions of air
regulation and moisture and dirt removal should be used where
applicable.

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.
Multi-viscosity motor oils like 10W30, should not
be used in an air compressor. They leave carbon
deposits on critical components, thus reducing
performance and compressor life. Use air
compressor oil only.
