Sound Considerations
Note: See Trane Engineering Bulletin Sound Ratings and
Installation Guide Optimus™ Water-Cooled
Chillers RLC-PRB015*-EN 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.
•
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
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).The expectation for our equipment is that attached
piping is fully supported by an independent structure/
system ,without being connected to the waterbox. Once in
place, the unit must be level within 1/2" (12.7 mm) across
the length and width of the unit. The Trane Company is not
responsible for equipment problems resulting from an
improperly designed or constructed foundation.

weights.
Place the manufacturer-supplied isolation pad assemblies
under the unit. Once in place, level the chiller within 1/4"
(6.35 mm) over its length and width.
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.

for unit operating
See
Figure 5, p. 19
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 the following:
Wye-Delta Starter Units:
AFD Unit Option:
Vent the evaporator, condenser and compressor pressure
relief valves in accordance with all local and national
codes. See
Table 8, p. 35
Make provisions in the equipment room to keep the chiller
from being exposed to freezing temperatures (32
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. See
p.
31. All local and national codes apply.
Access Restrictions
Door clearances are given in
submittals for specific "per unit" dimensional
information.
Rigging
Important:
If unit must be disassembled for
installation, see Engineering Bulletin RTHD-
SVB02*-EN, Disassembly Procedure,
Optimus™ Water-Cooled Chillers, for
instructions, including weights and rigging
instruction for components.
The Optimus™ chiller should be moved by lifting at
designated lift points only. See
p. 18
for overall unit weights. See
unit lifting point weights.
