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 man-
ually check the pressure in the refrigerant circuit. If
the refrigerant pressure is below 71 psig at 70oF (or
46 psig at 50oF), call a qualified service organization
and the appropriate Trane sales office.
Note: Pressure will be approximately 20 psig if shipped
with the optional nitrogen charge.
Location Requirements
Noise Considerations
• Refer to Trane Engineering Bulletin -Series R
®
Chiller
Sound Ratings and Installation Guide.
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 UC800.
•Sealallwallpenetrations.
Note: Consult an acoustical engineer for critical applica-
tions.
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 Table 10 for unit operating weights.
Once in place, level the chiller within 1/4” (6.35 mm) over
its length and width.
The Trane Company is not responsible for equipment
problems resulting from an improperly designed or con-
structed foundation.
Vibration Eliminators
• Provide rubber boot type isolators for all water pip-
ing at the unit.
• Provide flexible conduit for electrical connections to
the unit.
• Isolate all pipe hangers and be sure they are not sup-
ported 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 instal-
lation and maintenance personnel unrestricted access
to all service points. Refer to submittal drawings for the
unit dimensions.
Allow adequate clearance for condenser and compressor
servicing. A minimum of three feet is recommended for
compressor service and to provide sufficient clearance
for the opening of control panel doors. Refer to Figure
8 for minimum clearances required for condenser tube
service. In all cases, local codes will take precedence
over these recommendations.
Note: Required vertical clearance above the unit is 36”
(914.4 mm). There should be no piping or conduit
located over the compressor motor.
If the room configuration requires a variance to the
clearance dimensions, contact your Trane sales office
representative.
