For maintaining the receiver tank or system air pressure within
predetermined limits, the compressor may be operated with automatic
start & stop control or constant speed control regulation. The type of
regulation used depends upon the application.
ADDITIONAL REFERENCES
Unless otherwise stated, dimensions, weights and measurements are
provided in standard U.S. measure followed in parentheses by the
metric conversion. Any torque values given are stated in inch or foot
pounds followed by the Newton-meter equivalent in parentheses.
Electrical characteristics are given in voltage-phase-hertz.
RECEIPT & INSPECTION
Ensure adequate lifting equipment is available for unloading and
moving the unit to the installation site.
NOTE Lifting equipment must be properly rated for the
weight of the unit.
aCAUTION Lift the unit by the shipping skid only. Do not use
the motor lifting eye to lift the entire unit. The
motor lifting eye is for removing the motor from
the unit only.
aCAUTION! Do not work on or walk under the unit while it
is suspended.
Use suitable lifting equipment (i.e. forklift) to lift and transport the unit
to the installation site. Ensure the lifting equipment, straps, etc. are
capable of supporting the weight of the unit.
Before signing the delivery receipt, inspect for damage and missing
parts. If damage or missing parts are apparent, make the appropriate
notation on the delivery receipt, then sign the receipt. Immediately
contact the carrier for an inspection.
All material must be held in the receiving location for the carrier’s
inspection.
Delivery receipts that have been signed without a notation of damage or
missing parts are considered to be delivered “clear.” Subsequent claims
are then considered to be concealed damage claims. Settle damage
claims directly with the transportation company.
If you discover damage after receiving the unit (concealed damage), the
carrier must be notified within 15 days of receipt and an inspection must
be requested by telephone with confirmation in writing. On concealed
damage claims, the burden of establishing that the unit was damaged in
transit reverts back to the claimant.
Read the unit nameplate to verify it is the model ordered, and read the
motor nameplate to verify it is compatible with your electrical conditions.
Make sure electrical enclosures and components are appropriate for the
installation environment.
INSTALLATION
SELECTING A LOCATION
ELECTRIC MOTOR UNITS. For most electric motor units, select a
relatively clean and dry well-lighted indoor area with plenty of space for
proper ventilation, cooling air flow and accessibility. Provide 1,000 cubic
feet of fresh air per 5 horsepower. Locate the unit at least 15 inches (38
cm) from walls, and make sure the main power supply is clearly
identified and accessible.
Unless the electrical components of the unit are specially protected for
outdoor use, do not install an electric motor unit outdoors or in an area
that will expose the electrical components to rain, snow or sources of
appreciable moisture.
WARNING FOR UNITS EQUIPPED
WITH ELECTRIC DRAIN VALVE
aWARNING The electric drain valve incorporates arcing or
sparking parts, such as snap switches,
receptacles and the like that tend to produce
arcs or sparks and, therefore, when located in a
garage, the compressor should be in a room or
enclosure provided for the purpose, or the
electric drain valve should be 18 inches
(457 mm) or more above the floor.
AMBIENT TEMPERATURE CONSIDERATIONS. Ideal operating
temperatures are between 32°F and 100°F (0°C and 37.8°C). If
temperatures consistently drop below 32°F (0°C), install the
compressor in a heated area. If this is not possible, you must protect
safety/relief valves and drain valves from freezing. If temperatures are
consistently below 40°F (4.4°C), consider installing an external
crankcase heater kit, especially if the compressor has difficulty starting.
aCAUTION Never operate the compressor in temperatures
below -15°F (-26.1°C) or above 104°F (40°C).
HUMID AREAS. In frequently humid areas, moisture may form in the
pump and produce sludge 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
pump when it cools down and a “milky” appearance in petroleum
lubricant.
You may be able to prevent moisture from forming in the pump by
increasing ventilation, operating for longer intervals or installing an
external crankcase heater kit.
NOISE CONSIDERATIONS. Consult local officials for information
regarding acceptable noise levels in your area. To reduce excessive
noise, use vibration isolator pads or intake silencers, relocate the unit or
construct total enclosures or baffle walls.
MOUNTING
aWARNING Remove the unit from the skid before mounting.
The compressor must be bolted to a firm, level, solid foundation (such
as a concrete floor) using the vibration isolation pads provided with
the compressor. Installation on I-beams, open-grid flooring systems, or
non-solid surfaces is not recommended.
Failure to install the unit using the pads provided with the unit and in
accordance with the installation instructions as outlined in the
operator's manual may result in mechanical failure to the compressor
and cancellation of package warranty coverage. Ingersoll-Rand shall
bear no responsibility for equipment installed on non-approved
vibration isolation mounts or non-solid surfaces.
