MG6-OLVERT-3B Rev. 2 6/27/00
This product should be connected to a grounded,
metallic, permanent wiring system, or an equip-
ment-grounding terminal or lead on the product.
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!
Voltage and Circuit Protection
Refer to your Outfit Parts Manual 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 the air compressor is operated on. If the air
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 air compressors require a magnetic starter.
Check the specification chart in the Outfit Parts Manual to
see if required or not.
INSTALLATION (cont'd)
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 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 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.
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 air compressor life. Use air
compressor oil only.
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 air
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.
