SELECTINGA LOCATION

GENERAL° Select a clean, dry, welt-lighted indoor area with plenty
of space far proper cooling air flow and accessibility. Locate the unit
at least 12 inches (30 cm) from wails, and make sure the main

power supply is clearly identified and accessible
TEMPERATURE.. Ideal operating temperatures are between 32"F

and 100°F (0°C and 37.B_C) If temperatures consistently drop
below 32°F (0"C), locale the unit inside a heated building !f th_s is
not possible, you must protect safety!relief valves and drain valves

from freezing

CAUTION Never operate in temperatures below 20°F (_6.6°C)

or above 125°F (5t.0°C)..

HUMID AREAS. In frequently humid areas, moisture may form in

the bare pump and produce sfudge in the lubricant, causing running
parts to wear out prematurely Excessive moisture is especially
likely to occur if the unit is located in an unheated area that is
subject to large temperature changes Two signs of excessive

humidity are external condensation on the bare pump when it cools

down and a "_mllky_appearance in petroleum compressor lubricant

You may be able to prevent moisture from forming in the bare pump
by increasing ventilation, operating for longer intervals or installing

a crankcase heater kit
NOISE CONSIDERATIONS Consull local officials [or information

regarding acceptable noise levels in your area To reduce excessive
noise, use vibralion isolator pads or intake silencers, relocate the
unit or construct total enclosures orbaffle waits

PERMANENT MOUNTING

WARNING Remove the unit from the skid before mounting..

The unit must be permanently mounted When mounting the unit.

ELECTRICAL WIRING

_, WARNING Electrical installation and service shoutd be

performed by a qualified electrician who is familiar
with all applicable loca!, state and federal laws and
regu}attons r

NOTE This product should be connected to a grounded,

metallic, permanent wiring system, or an
equipment-grounding terminal or lead on the

product.

GENERAL The motor rating, as shown on the motor nameplate,

and the power supply must have compatible voltage, phase and
hertz characleristics

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 conneclions should be provided with the motor If not. refer
to the National EIeclric Code (NEC) or applicable local, stale and
federa_ laws and regulations. If other electrical equipment is

connected to the same circuit, the total electrica! 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.

GENERAL

Your air compressor was designed for f 00% continuous duty
operation with the use of Ingersoll-Rand synthetic compressor

lubricant and 60% continuous duty operation with the use of
petroleum lubricant In other words, synthetic lubricant allows the
compressor to pump continuously without cycling Petroleum
lubricant limits the compressor to a maximum of 36 minutes of
pumping time per hour The compressor should not cycle more than
10 times per hour
