Humid Areas; Mounting - Ingersoll Rand 2340 Manuel De L'utilisateur

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
compressor 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 compressor or construct total enclosures
or baffle walls.

MOUNTING

WARNING
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.
NOTICE
•
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.
•
Secure the compressor to a solid, flat and level mounting
surface.
•
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.
•
Do not install the compressor on I-beams, open-grid flooring
systems, or non-solid surfaces.
•
Ingersoll Rand shall bear no responsibility for equipment
installed on non-approved vibration isolation mounts or pads
or non-solid surfaces.
CONCRETE FLOORS (ELECTRIC MOTOR OR GASOLINE
ENGINE POWERED COMPRESSORS)
NOTICE
Mounting hardware kit 46822243 is available for mounting 3-
footed vertical tank compressors to concrete floors.
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" deep holes using a concrete drill bit sized per the
following table.

NOTICE
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 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 fill in the open elevation under the
foot. After all required shims have been inserted, re-tighten the nuts
to 10 ft. lb.
Do not secure uneven feet tightly, as this will cause excessive stress on
the receiver tank.
