Installation - Mechanical
Storage
If the chiller is to be stored more than one month prior to
installation, observe the following precautions:
• Do not remove the protective coverings from the
electrical panel.
• Store the chiller in a dry, vibration-free, secure area.
• At least every three months, attach a gauge and
manually check the pressure in the refrigerant circuit.
If the refrigerant pressure is below 3.4 bar at 21°C (2 bar
at 10 °C), call a qualified service organization and the
appropriate Trane sales office.
NOTE:
Pressure will be approximately 1.0 bar if shipped
with the optional nitrogen charge.
Noise Considerations
• Refer to Engineering Bulletin for sound consideration
applications.
• Locate the unit away from sound-sensitive areas.
• Install the isolation pads under the unit. Refer to “Unit
Isolation.”
• Install rubber vibration isolators in all water piping.
• Use flexible electrical conduit for final connection to the
Tracer UC800.
• Seal all wall penetrations.
NOTE:
Consult an acoustical engineer for critical
applications.
Foundation
Provide rigid, non-warping mounting pads or a concrete
foundation of sufficient strength and mass to support the
chiller operating weight (including completed piping and
full operating charges of refrigerant, oil and water).
Refer to General information for unit operating weights.
Once in place, level the chiller within 5 mm over its
length and width.
The manufacturer is not responsible for equipment
problems resulting from an improperly designed or
constructed foundation.
Vibration Eliminators
• Provide rubber boot type isolators for all water piping
at the unit.
• Provide flexible conduit for electrical connections to the
unit.
• 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.
Clearances
Provide enough space around the unit to allow the
installation and maintenance personnel unrestricted
access to all service points. A minimum of 1 m is
recommended for compressor service and to provide
sufficient clearance for the opening of control panel
doors. In all cases, local codes will take precedence
over these recommendations. If the room configuration
requires a variance to the clearance dimensions, contact
your sales representative.
NOTE:
Required vertical clearance above the unit is at
least 1 m. There should be no piping or conduit located
over the compressor motor.
NOTE:
Maximum clearances are given. Depending on
the unit configuration, some units may require less
clearance than others in the same category.
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 40°C. Vent the pressure
relief valves in accordance with all local and national
codes. Refer to “Pressure Relief Valves”. Make provisions
in the equipment room to keep the chiller from being
exposed to ambient temperatures below 10°C.
Water Drainage
Locate the unit near a large capacity drain for water
vessel drain-down during shutdown or repair. Condenser
and evaporator water pipes are provided with drain
connections. Refer to “Water Piping.” All local and
national codes apply.
Access Restrictions
Refer to the unit submittals for specific dimensional
information (documents supplied in document package
coming with unit).
