ELECTRICAL WIRING & GROUNDING ________________
•
WARNING
Any electrical installation and service required
should be performed by a qualified electrician
who is familiar with all applicable local, state
and federal laws and regulations.
NOTE
This product should be connected to a
grounded, metallic, permanent wiring system.
NOTE
Ingersoll Rand recommends the use of a
d e d i c a t e d 2 0 A M P o u t l e t f o r t h i s a i r
compressor. A 15 AMP outlet may be sufficient
for some applications.
GENERAL.
The motor rating, as shown on the motor nameplate,
and the power supply must have compatible voltage, phase and
hertz characteristics.
WIRE SIZE.
The electrical wiring between the power supply and
electric motor varies according to motor horsepower. Power
leads must be adequately sized to protect against excessive
voltage drop during start-up. Information for selecting the proper
wire size and securing connections should be provided with the
motor. If not, refer to the National Electric Code (NEC) or
applicable local, state and federal laws and regulations. If other
electrical equipment is connected to the same circuit, the total
electrical load must be considered in selecting the proper wire
size. DO NOT USE UNDERSIZE WIRE.
FUSES.
Refer to the National Electric Code to determine the
proper fuse or circuit breaker rating required. When selecting
fuses, remember the momentary starting current of an electric
motor is greater than its full load current. Time-delay or
“slow-blow” fuses are recommended.
GROUNDING.
The unit is equipped with a power cord having a
grounding wire and an appropriate grounding plug. The plug
must be used with an outlet that has been installed and grounded
in accordance with all local codes and ordinances. The outlet
must have the same configuration as the plug. DO NOT USE AN
ADAPTER.
•
WARNING
In the event of a short circuit, grounding
reduces the risk of shock by providing an
escape for the electric current. The unit must
be properly grounded.
•
DANGER
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 flat
blade terminal. The wire with insulation having
an outer surface that is green with or without
yellow stripes is the grounding wire.
Check with a qualified electrician or service technician if the
grounding instructions are not completely understood, or if in
doubt as to whether the product is properly grounded. Do not
modify the plug provided; if it will not fit the outlet, have the
proper outlet installed by a qualified electrician.
This product is for use on a nominal 115-volt circuit and has a
grounding plug that looks like the plug illustrated below. Make
sure the product is connected to an outlet having the same
configuration as the plug. No adapter should be used with this
product.
EXTENSION CORDS.
It is preferable to use extra air hose
instead of an extension cord to avoid voltage drop and power
loss to the motor, and to prevent overheating. If an extension
cord must be used, ensure it meets the following criteria:
l
Three wire cord with a three blade grounding plug, and a
three slot outlet that will accept the plug on the unit.
l
Good condition.
l
No longer than 50 feet.
l
12 gauge or larger.
NOTE
Wire size increases as gauge number
decreases. For example, 10 AWG and 8 AWG
wire is acceptable, whereas 14 or 16 AWG are
NOT acceptable.
COMPRESSOR LUBRICATION_______________________
•
CAUTION
Do not operate without lubricant or with
inadequate lubricant. Ingersoll Rand is not
responsible for compressor failure caused by
inadequate lubrication.
NOTE
The compressor is shipped without oil in the
crankcase. A bottle of oil is supplied. Follow
the oil filling procedures in this manual.
NOTE
A plastic plug is inserted in the oil fill opening.
Remove this plug and replace it with the oil
dipstick provided before operating the unit.
SYNTHETIC LUBRICANT.
We recommend Ingersoll Rand
“All-Season Select” synthetic lubricant.
ALTERNATE LUBRICANTS.
You may use a petroleum-based
lubricant that is premium quality, does not contain detergents,
contains only anti-rust, anti-oxidation, and anti-foam agents as
additives, has a flashpoint of 440°F (227°C) or higher, and has
an auto-ignition point of 650°F (343°C) or higher.
See the petroleum lubricant viscosity table below. The table is
intended as a general guide only. Heavy duty operating
conditions require heavier viscosities. Refer specific operating
conditions to your dealer for recommendations.

synthetic lubricant later on, the compressor valves must be
