General Information
Note:
Immediately report any unit
damage incurred during handling or
installation at the job site to Trane
sales office.
Rigging
Lifting is the recommended method
for moving chillers. Suggested lifting
arrangements for standard and heat-
recovery 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.
WARNING
Improper Unit Lift!
LIFT THE CHILLER HORIZONTALLY.
Failure to do so could result in death
or serious injury and equipment
damage.
See Tables 2, 3 and 5 for shipping
weights.
Refer to lifting arrangement and
rigging in Figure 5. Notice that the
lifting beam used to lift the unit must
be at least 16 feet minimum effective
length.
To lift the chiller properly, insert
clevis connections at the points
indicated in Figure 5, a 2” [51 mm]
diameter lifting hole is provided at
each of these points. Next attach the
lifting chains or cables.
Once the lifting cables are in place,
attach a safety chain or cable
between the first-stage casting of the
compressor and the lifting beam. To
do this, remove a restraining bolt
from the compressor first-stage
casting and replace it with an
eyebolt.
Note:
There should not be tension
on this safety cable; it is used only to
prevent the unit from rolling during
the lift.
If installing chiller onto spring
isolators, follow instructions given
on page 22 and Figures 8 and 9.
Follow instructions provided by
spring isolator manufacturer, being
careful to not damage isolator
adjustment bolt.
When the lift is complete, 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 colt 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
compressor and remove it from
the unit. Be sure to contact a
qualified service organization for
specific rigging instructions. Do
not attempt to rotate chiller on to
side.
CAUTION
Loss of Oil!
IF THE UNIT WILL BE LIFTED AT AN
ANGLE GREATER THAN 15° FROM
END-TO-END, REMOVE THE OIL
FROM THE OIL TANK. Failure to do
so, will cause oil to drain out of oil
tank into other areas of 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.
Note:
The oil tank with the
refrigerant pump is mounted under
the condenser and may be damaged
by a fork truck.
CAUTION
Improper Unit Lift!
DO NOT USE A FORKLIFT TO
REMOVE THE CHILLER. Using a
forklift can result in damaged
equipment.
CAUTION
Compressor
Misalignment!
CONSULT THE TRANE COMPANY
BEFORE LIFTING THE
COMPRESSOR/MOTOR ASSEMBLY
FROM THE SHELLS WITHOUT
FACTORY-INSTALLED DOWELING
IN THE COMPRESSOR CASTING
FLANGES. Failure to do so can result
in misalignment of the compressor
castings.
3. If removal of the compressor or
economizer assembly is necessary
to move the chiller into its
operating location, contact The
Trane Company for special
instructions concerning chiller
disassembly and reassembly
procedures.
CAUTION
Wiring Damage!
BE CAREFUL TO AVOID DAMAGING
UNIT WIRING DURING RIGGING,
ASSEMBLY AND DISASSEMBLY.
