Installation: Mechanical

Operating Environment

Important:
• The standard chiller is designed for indoor use only
and as such has NEMA Type 1 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.
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
maximum ambient temperature for chiller operation is
104°F (40°C).
NOTICE:
Equipment Failure!
Unit operating at ambient temperatures exceeding
104°F (40°C) could fatigue the unit's rupture disk,
causing it to break at a reduced refrigerant pressure
(<15 psig [<103.4 kPaG]). Starter component damage
could also occur 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.

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 in. (1.6 mm) over its length and width when set into
place on the mounting surface.
approximate weights for various chiller sizes and options.
Note: For specific weight information, refer to the unit
submittal package.
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.
Note: The lifting beam used for Simplex units must be at
least 16 feet (4.8768 meters) long.

Table 2, p. 13 shows

WARNING
Heavy Objects!
Failure to properly lift unit could result in death or
serious injury, or equipment or property-only damage.
Do not use cables (chains or slings) except as shown in
Figure 4, p. 17. 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.
WARNING
Improper Unit Lift!
Failure to properly lift unit could result in death or
serious injury, or equipment or property-only damage.
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.
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

1. Insert clevis connections at the points indicated in
Figure 4, p. 17. A 2 in. (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.
Important: 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
chiller feet (refer to "Unit Isolation, " p. 18
instructions).
Note: Follow instructions provided by the spring
isolator manufacturer, being careful to not
damage isolator adjustment bolt.
5. Once the isolators are in place, lower the chiller—
working from end to end—in small increments to
maintain stability.
6. When lift is complete, detach the clevis connections
and safety chain.
