Installation: Mechanical
Operating Environment
Important:
•
The standard chiller is designed for
INDOOR USE ONLY and as such has
NEMA Type 1 or IP 20 enclosures.
•
For chillers in unheated equipment rooms,
contact your local Trane Service Agency
for methods to ensure that the oil
temperature is maintained suitable for
proper operation of the chiller.
NOTICE
Equipment Damage!
Failure to protect the unit from freezing could result in
equipment damage.
If fluid has been added to the piping, the unit must be
protected from freezing. Freeze damage from an
unheated equipment room is not the Trane company's
responsibility. These are indoor units.
NOTICE
Equipment Failure!
Unit operating at ambient temperatures exceeding
104°F (40°C) could result in AFD/starter component
damage due to the panel's inability to dissipate heat
adequately.
If any of these adverse operating conditions are
present, take necessary action to improve the
equipment room environment.
To ensure that electrical components operate properly, do
NOT locate the chiller in an area exposed to dust, dirt,
corrosive fumes, or excessive heat and humidity. The
ambient temperature range for chiller operation is 34°F to
104°F (1.1°C to 40°C).
Foundation Requirements
Chiller mounting surface must be:
•
Rigid non-warping mounting pads or a concrete
foundation, and
•
Able to support the chiller at its full operating weight
(including completed piping and full operating charges
of refrigerant, oil, and water).
For proper unit operation, the chiller must be level within
1/16 in. (1.6 mm) over its length and width when set into
place on the mounting surface. Refer to
Unit," p. 25
for more information. For approximate weights
for various chiller sizes and options in pounds and
kilograms, refer to
"Weights (lb)," p. 19
(kg)," p.
20, respectively.
Note: For specific weight information, refer to the unit
submittal package.

"Leveling the
and
"Weights
Important: Trane will not assume responsibility for
equipment problems resulting from an
improperly designed or constructed
foundation.
Rigging
Lifting is the recommended method for moving chillers.
Suggested lifting arrangements for standard units are
described in
"Standard Chiller Lift," p.
WARNING
Heavy Object!
Failure to follow instructions below could result in
unit dropping which could result in death or serious
injury, and equipment or property-only damage.
Ensure that all the lifting equipment used is properly
rated for the weight of the unit being lifted. Each of the
cables (chains or slings), hooks, and shackles used to
lift the unit must be capable of supporting the entire
weight of the unit. Lifting cables (chains or slings)
may not be of the same length. Adjust as necessary
for even unit lift.
NOTICE
Wiring Damage!
Damage to unit wiring could result in equipment
failure.
Care must be taken during rigging, assembly and
disassembly to avoid damaging unit wiring.
Standard Chiller Lift
WARNING
Proper Diameter Clevis Required to Lift
Units!
Failure to follow instructions below could result in
death or serious injury.
A clevis with a 2.25-in. (5.72-cm) diameter pin MUST
be used to lift these units. Using a smaller clevis
would cause too much stress to the 2.25-in. (5.72-cm)
lifting holes which could result in pull-out of the lifting
holes causing the unit to drop from the rigging.
1. Insert rigging shackles at the points indicated in the
following figure. A 1.25 in. (31.8 mm) diameter lifting
hole is provided at each of these points.
2. Attach the lifting chains or cables.
3. After the lifting cables are in place, attach a safety
chain or cable between the first-stage casing of the
compressor and the lifting beam.
Important: There should NOT be tension on this safety
cable; the cable is used only to prevent the
unit from rolling during the lift.
