Note: Immediately report any unit
damage incurred during handling or
installation at the job site to the
Trane sales office.
Rigging
Lifting is the recommended method
for moving chillers. Suggested lifting
arrangements for standard units are
illustrated in Figure 5.
Note that each of the cables used to
lift the unit must be capable of
supporting the entire weight of the
chiller. (See Table 2 for unit shipping
and operating weights.) Notice that
the lifting beam used to lift the unit
must be at least 23 feet long.
See Figure 5 and Table 2 for
guidance in selecting cable or sling
lengths.
WARNING
Test Lift!
Verify chiller remains horizontal.
To avoid serious injury and possible
equipment damage, lift the chiller
horizontally; use the lifting
arrangement and rigging shown in
Figure 5. Failure to lift unit as
recommended could result in death
or serious injury or lead to
equipment damage.

General Information
To lift the chiller properly, insert
clevis connections at the points
indicated in Figure 5; a 2-1/2"
diameter lifting hole is provided at
each of these points. Next, attach the
lifting cables or slings.
Once the lifting cables are in place,
attach a safety cable or sling
between the first-stage casting of the
compressor and the lifting beam. To
do this, remove a retaining bolt from
the compressor first-stage casting
and replace it with an eyebolt, or
swivel clevis.
Note: There should not be tension
on this safety cable; it is used only to
prevent the unit from rolling during
the lift.
When the lift is completed, detach
the clevis connections and safety
chain, then remove the eyebolt that
was used to secure the safety chain
to the compressor, and reinstall the
retaining bolt in its place. If the chiller
cannot be moved using the
conventional rigging method just
described, consider these points.
1. If job site conditions require
rigging of the chiller at an angle
greater than 45° from horizontal
(end-to-end), dowel-pin the com-
pressor and remove it from the
unit. Be sure to contact a qualified
service organization for specific
rigging instructions.
CAUTION
Oil Loss!
To prevent oil migration out of the
oil tank during lifting procedures,
remove the oil from the oil tank if
the unit will be lifted at any angle
greater than 15° from horizontal
end-to-end. If oil is allowed to run
out of the oil tank into other areas of
the chiller, it will be extremely
difficult to return the oil to the oil
tank even during operation.
2. When lifting the chiller is either
impractical or undesirable, attach
cables or chains to the jacking
slots shown in Figure 5; then push
or pull the unit across a smooth
surface. Should the chiller be on a
shipping skid, it is not necessary to
remove the shipping skid from the
chiller before moving it into place.
CAUTION
Equipment Damage!
To prevent possible equipment
damage, do not use a fork lift to
move the chiller!
CAUTION
Compressor Alignment!
Lifting the compressor/motor
assembly from the shells without
factory-installed doweling in the
compressor casting flanges may
result in misalignment of the
compressor castings.
3. Position isolator pads (or spring
isolators) beneath the chiller feet;
see "Unit Isolation" section for
instructions.
4. Once the isolators are in place,
lower the chiller; again, work from
end to end in small increments to
maintain stability.
