Installation, Operation and Maintenance 2 - 1
Installation - Mechanical
Storage
If the chiller is to be stored at least one month prior to
installation, observe the following precautions:
q Do not remove the protective coverings from the
electrical panel.
q Store the chiller in a dry, vibration-free, secure
area.
q At least every three months, attach a gauge and
manually check the pressure in the refrigerant
circuit. If the refrigerant pressure is below 71 psig
at 70
°
F (or 46 psig at 50
°
F), 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 RLC-EB-3 for
sound consideration applications.
q Locate the unit away from sound-sensitive areas.
q Install the isolation pads under the unit. Refer to
“Unit Isolation.”
q Install rubber vibration isolators in all water piping.
q Use flexible electrical conduit for final connection
to the UCP2.
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
Table 8
and
Table
7
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
constructed foundation.
Vibration Eliminators
q Provide rubber boot type isolators for all water
piping at the unit.
q Provide flexible conduit for electrical connections
to the unit.
q Isolate all pipe hangers and be sure they are not
supported by main structure beams that could
introduce vibration into occupied spaces.
q 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. 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 4
for minimum clearances
required for condenser tube service. In all cases,
local codes will take precedence over these
recommendations.
NOTES: 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.
