Location Requirements
Noise Considerations
• Refer toTrane 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.
• 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
applicable operating weight (i.e., including completed
piping, and full operating charges of refrigerant, oil and
water). See “Unit Dimensions/Weights” chapter for unit
operating weights. Once in place, the unit must be level
within 1/4” (6.4 mm) over its length and width.TheTrane
Company is not responsible 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, to provide sufficient clearance for the
opening of control panel doors and unit service. Refer to
the chapter on “Unit Dimensions/Weights” for minimum
clearances. In all cases, local codes which require
additional clearances 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 unit
configuration requires a variance to the clearance
dimensions, contact yourTrane Sales Office
Representative. Also refer toTrane Engineering
Bulletins for application information on RTWD/
RTUD chillers.
Rigging
The Model RTWD/RTUD chiller should be moved by lifting,
unless the unit is ordered with the “Base Rail Forklifting”
option. Refer to the unit model number, digit 46, for more
details.
Refer to Table 15, p. 28 thru Table 20, p. 30 for typical unit
lifting weights and Table 30, p. 39 thru Table 35, p. 40 for
center of gravity dimensions. Refer to the rigging label
attached to the unit for further details.\
Lifting Procedure
Attach chains or cables to lifting beam, as shown in
Figure .Lifting beam crossbars MUST be positioned so
lifting cables do not contact the sides of the unit.Attach the
anti-rolling cable to the circuit 2 compressor suction pipe.
Adjust as necessary for even level lift.
WARNING
Heavy Objects!
• Ensure that all the lifting equipment used is properly
rated for the weight of the unit being lifted. Each of
the cables (chains or slings), hooks, and shackles
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.
• The high center of gravity on this unit requires the use
of an anti-rolling cable (chain or sling).To prevent unit
from rolling, attach cable (chain or sling) with no
tension and minimal slack around compressor
suction pipe as shown.
• Do not use fork lift to move or lift unit unless unit has
lifting base with locations marked by caution labels
installed.
Other lifting arrangements could cause equipment or
property damage. Failure to follow instructions above
or properly lift unit could result in unit dropping and
possibly crushing operator/technician which could
result in death or serious injury.
WARNING
Improper Unit Lift!
Test lift unit approximately 24 inches to verify proper
center of gravity lift point.To avoid dropping of unit,
reposition lifting point if unit is not level. Failure to
properly lift unit could result in unit dropping and
possibly crushing operator/technician which could
result in death or serious injury and possible equipment
or property-only damage.
