Installation: Mechanical
Location Requirements
Sound Considerations
• Install rubber vibration isolators in all water piping.
• Isolate all pipe hangers and be sure they are not
supported by main structure beams that could
introduce vibration into occupied spaces.
• Make sure that the piping does not put additional stress
on the unit.
Note: Do not use metal braided type eliminators on the
water piping. Metal braided eliminators are not
effective at the frequencies at which the unit will
operate.
• Use flexible electrical conduit.
• Seal all wall penetrations.
Note: Consult an acoustical engineer for critical
applications.
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 and water).
For proper unit operation, the chiller must be level within 1/
4 in. (6.35 mm) over its length and width when set into
place on the mounting surface. Refer to “Leveling the
Unit,” p. 21 for more information. For minimum and
maximum chiller weights/dimensions in pounds/inches and
kilograms/millimeters, refer to “Weights (lb),” p. 14 and
“Weights (kg),” p. 15, respectively.
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.
Clearances
Provide enough space around the unit to allow the
installation and maintenance personnel unrestricted
access to all service points. Refer to submittal drawings for
the unit dimensions.
Refer to “Unit Clearances,” p. 13 for minimum clearances
required for service. In all cases, local codes will take
precedence over these recommendations.
Ventilation
The unit produces heat even though the compressor is
cooled by the refrigerant. Make provisions to remove heat
generated by unit operation from the equipment room.
Ventilation must be adequate to maintain an ambient
temperature lower than 104°F (40°C).
Vent the evaporator, condenser, and compressor pressure
relief valves in accordance with all local and national
codes. Refer to “Refrigerant Pressure Relief Valve
Venting,” p. 22.
Make provisions in the equipment room to keep the chiller
from being exposed to freezing temperatures (32°F [0°C]).
Water Drainage
Locate the unit near a large capacity drain for water vessel
drain-down during shutdown or repair. Condensers and
evaporators are provided with drain connections. Refer to
“,”. All local and national codes apply.
Access Restrictions
Door clearances are provided in “Unit Clearances,” p. 13.
See unit submittals for specific "per unit" dimensional
information.
Operating Environment
Important:
• The standard chiller is designed for
INDOOR USE ONLY and as such has
NEMA Type 1 enclosures.
• The warranty requires an equipment room/
chiller environment surrounding the NEMA
1 chiller to be maintained in the
temperature range of 34°F to 104°F (1.1°C
to 40°C) AND at less than 95% relative
humidity (non-condensing conditions). If
your equipment room/chiller environment
does not meet these conditions, contact
your local Trane Service Agency
immediately.
• Chiller required to be installed in a secure
location with restricted access.
• This appliance is not intended for use by
persons (including children) with reduced
physical, sensory, or mental capabilities, or
lack of experience and knkowledge unless
they have been given supervision or
instruction concerning use of the appliance
by a person responsible for their safety.
• Children are required to be supervised to
ensure that they do not play with the
appliance.
