Notes:
1.
Lifting chains (or cables) are not the same length between point A and B, or between points A and C. Adjust as necessary for an even lift.
2.
Lifting holes provided on chillers to attach chains are 2-1/2 in. (63.5 mm) in diameter.
3.
Attach safety chain (or cable) as shown, and without tension. The safety chain is not used for lifting, but is there to prevent the unit from rolling.
4.
Do NOT fork-lift the unit.

Special Lift Requirements

NOTICE
Oil Loss!
Failure to prevent oil migration out of the oil tank
could result in equipment failure or property-only
damage.
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.
NOTICE
Equipment Damage!
Moving the chiller using a fork lift could result in
equipment or property-only damage.
Do not use a fork lift to move the chiller!
NOTICE
Compressor Alignment!
Failure to preserve compressor alignment could
result in equipment or property-only damage.
Lifting the compressor/motor assembly from the
shells without factory-installed doweling in the
compressor casting flanges could result in
misalignment of the compressor castings.
If the chiller cannot be moved using a standard chiller lift,
consider the following:
When job site conditions require rigging of the chiller at
an angle greater than 30° from horizontal (end-to-end),
the unit may require removal of the compressor.
Contact Trane or an agent of Trane specifically
authorized to perform start-up and warranty of Trane

work. For more information, refer to

Note: Disassembly and reassembly work includes
dowel-pinning the compressor and removing it
from the unit. Contact Trane or an agent of Trane
specifically authorized to perform start-up and
warranty of Trane
instructions. Do NOT attempt to rotate the chiller
onto its side.
When lifting the chiller is either impractical or
undesirable, attach cables or chains to the jacking slots
shown in the figure in
push or pull the unit across a smooth surface. Should
the chiller be on a shipping skid, it is not necessary to
remove the skid from the chiller before moving it into
place.
If removal of the compressor or economizer assembly
is necessary to move the chiller to the operating
location, contact Trane. Also refer to
Information," p.

Unit Isolation

To minimize sound and vibration transmission through the
building structure and to ensure proper weight distribution
over the mounting surface, always install isolation pads or
spring isolators under the chiller feet.
Notes:
Isolation pads (refer to the figure in
Pads," p. 24
unless spring isolators are specified on the
sales order.
The center support leg of the Duplex™
CenTraVac™ chiller is approximately 1/2 in.
(12.7 mm) shorter than the end support legs,
and a field-supplied steel shim of appropriate
thickness will be required under the center
support leg to ensure the chiller's weight is
evenly distributed. If isolation pads are used,
®
the shim used should be of the same
dimensions as the chiller's center foot, or larger,
and it should be placed under the isolation pads.
If isolation springs are used, then any shims
used with them should be placed under the
springs and must be large enough to properly
support the spring base.
