Installation Mechanical
Operating Environment
To assure 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 for chiller operation is
+5 °C to +40 °C
D
Notice
Equipment Failure!
Unit operating at ambient temperatures exceed-
ing 110°F (43°C) can fatigue the unit’s rupture disc,
causing it to break at a reduced refrigerant pressure
(<15 psig).Starter component damage can also oc-
cur because of the panel’s inability to dissipate heat
adequately. If any of these adverse operating condi-
tions are present, take whatever action is necessary
to improve the equipment room environment.
Foundation Requirements
Chiller mounting surface must be:
•
Rigid non-warping mounting pads or a concrete
foundation.
•
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” (1.6 mm) over its length and width when set into
place on the mounting surface.
The tables provided in this manual show approximate
weights for various chiller sizes and options. For more
specific weight information refer to the unit submittal
package.
Trane will not assume responsibility for equipment
problems resulting from an improperly designed or con-
structed foundation.
Rigging
Lifting is the recommended method for moving chillers.
Suggested lifting arrangements for standard units are
described in the standard chiller lift section.
Note:
The lifting beam used for simplex units must be
at least 16 feet (4.88 meters) long.

WARNING
Heavy Objects!
Do not use cables (chains or slings) except as shown in
. Each of the cables (chains or slings)
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. Failure to properly lift unit
could result in death or serious injury, or equipment or
property-only damage.

WARNING
Improper Unit Lift!
Test lift unit approximately 24 inches (61 cm) to verify
proper center of gravity lift point. To avoid dropping of
unit, reposition lifting point if unit is not level. Do not
lift chiller utilizing waterbox lifting lug. Waterbox lift-
ing lug is to be used only for removing waterbox from
chiller. Do not lift chiller utilizing elbow lifting tab.
Elbow lifting tab and approved clevis are used when
removing elbow from chiller. Failure to properly lift
unit could result in death or serious injury, or equip-
ment or property-only damage.

Notice
Wiring Damage!
Care must be taken during rigging, assembly and dis-
assembly to avoid damaging unit wiring. Damage to
unit wiring could result in equipment failure.
Standard chiller lift
1. Insert clevis connections at the points indicated in
. A 2 inch (50.8 mm) diameter lifting
hole is provided at each of these points.
2. Attach the lifting chains or cables.
3. Once the lifting cables are in place, attach a safety
chain or cable between the first-stage casing of the
compressor and the lifting beam. There should not be
tension on this safety cable; the cable is used only to
prevent the unit from rolling during the lift.
4. Position isolator pads or spring isolators beneath the
for instruc-
tions).
Note:
Follow instructions provided by spring isolator
manufacturer, being careful to not damage isola-
tor adjustment bolt.
5. Once the isolators are in place, lower the chiller work-
ing from end to end in small increments to maintain
stability.
6. When lift is complete, detach the clevis connections
and safety chain.
