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 45° 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
®
products regarding the disassembly and reassembly
work. For more information, refer to “Factory Warranty
Information,” p. 3.
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
®
products for specific rigging
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 “Standard Chiller Lift,” p. 25; 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 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 “Factory Warranty
Information,” p. 3.
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.
Note: Isolation pads (refer to the figure in “Isolation
Pads,” p. 27) are provided with each chiller unless
spring isolators are specified on the sales order.
Specific isolator loading data is provided in the unit
submittal package. If necessary, contact your local Trane
sales office for further information.
Important: When determining placement of isolation pads
or spring isolators, remember that the control
panel side of the unit is always designated as
the front side of the unit.
Isolation Pads
When the unit is ready for final placement, position isolation
pads (18-in. [457.2-mm] sides) end for end under the full
length of the chiller leg. The pads measure 9 in. × 18 in.
(228.6 mm x 457.2 mm) and on some units there may be
small gaps between pads. Pads are provided to cover
entire foot. Place pad flush with the outside edge of the
chiller foot and leave excess material under the chiller.
Figure 6. Isolation pad and dimensions
A = 3/8 in. (9.5 mm)
B = 18 in. (457.2 mm)
C = 9 in. (228.6 mm)
Remember that the chiller must be level within 1/16 in.
(1.6 mm) over its length and width after it is lowered onto
the isolation pads. In addition, all piping connected to the
chiller must be properly isolated and supported so that it
does not place any stress on the unit.
Spring Isolators
Spring isolators should be considered whenever chiller
installation is planned for an upper story location. Base
isolator placement is shown in the following figure.
