n Selecting A Location
General
n
Select a clean, dry, well-lighted indoor area with plenty of space for proper
cooling air flow and accessibility. Locate the unit at least 12 inches (30 cm) from
walls, and make sure the main power supply is clearly identified and accessible.
Temperature
n
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), locate the unit inside a heated
building. If this is not possible, you must protect safety/relief valves and drain
valves from freezing.
l Never operate in temperatures below 20°F (-6.6°C) or above 120°F
(48.9°C).
Humid Areas
n
In frequently humid areas, moisture may form in the bare 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 bare pump when it cools down and a "milky"
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
n
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.
n Permanent Mounting
THIS UNIT MUST BE INSTALLED ON A
LEVEL FLOOR AND TANK FEET MUST
BE SHIMMED PER THE OWNERS MANUAL.
l Remove the compressor from the skid before mounting. Refer to the
RECEIPT & INSPECTION section of this manual for information on lifting
and handling the compressor.
l Local codes may mandate specific mounting requirements including,
but not limited to, the use of vibration isolation mounts or pads.
Mounting kits including vibration isolation mounts or pads may be
ordered through your Ingersoll Rand dealer if not included with the
compressor. Consult your local Ingersoll Rand dealer for more
information.
l Secure the compressor to a solid, flat and level mounting surface.
l If vibration isolation mounts or pads are included with your
compressor, they must be properly installed. Failure to install the
compressor using the vibration isolation mounts or pads provided with
the compressor and in accordance with the installation instructions
may result in mechanical failure to the compressor and cancellation of
warranty coverage.
l Do not install the compressor on I-beams, open-grid flooring systems,
or non-solid surfaces.
l Ingersoll Rand shall bear no responsibility for equipment installed on
non-approved vibration isolation mounts or pads or non-solid surfaces.
To mount the compressor to a concrete surface, use the following procedure:
1. Mark the location of the mounting holes.
2. Drill 2-1/4 h deep holes using a ½" concrete drill bit.
l It may be helpful to use a piece of tape on the drill bit to mark the
proper depth.

3. Drill a hole through the center of each isolation pad (if supplied or mandated by
local codes).
4. Drive the anchors into the mounting holes with the threaded portion up.
5. Place the isolation pads over the anchors as shown in the illustration below.
6. Position the compressor over the drilled holes and slowly lower the compressor
feet over the holes.
7. Install the foundation bolts.
8. Install the nuts and torque each in a criss-cross pattern to 10 ft. lb.
Typical Permanent Mounting
A = Mounting surface
B = Foundation bolt / anchor
C = Isolation pad (if supplied or required by local codes)
D = Compressor mounting foot
E = Washer
F = Nut
After all mounting nuts are installed, check for receiver stress by loosening each
nut individually to check for upward movement of the foot. Upward movement
indicates the requirement for an appropriately sized metal shim to fi ll in the
open elevation under the foot. After all required shims have been inserted,
re-tighten the nuts to 10 ft. lb.
n Installing The Air Inlet Filter
CAUTION
l Do not operate the unit without the air inlet filter(s).
If the air around the unit is relatively free of dirt, install the air inlet filter at the
inlet connection at the bare pump. If remote air inlet piping or heavy duty
filtration is required, contact your dealer for information.
