General Installation Information
•
Please read and take heed of the water piping system
flushing procedure and water treatment requirements
found in
"Appendix B," p. 53
prepare and maintain an efficient and healthy chiller
system that utilizes brazed plate heat exchangers.
•
Valves in the water piping upstream and downstream of
the evaporator and condenser are installed on each
CICD chiller to isolate the heat exchangers for
maintenance and to balance/trim the system.
•
Supply and install condenser water control valve(s).
See also Trane publication RLC-PRB021-EN, available
from Trane Sales Offices, for additional technical
assistance. Provisions must be made for the control of
condenser water that results in stable saturated
condensing temperature between 80°F and 145°F
through all steady state, part load and transient
operating conditions. Trane recommends the optional
factory-installed integral water regulating valve
controlled by the unit controller.
•
Supply and install flow switch or other approved flow
proving device in the chilled water piping. Interlock this
switch with the controller to ensure that the unit can
only operate when water flow is established. See
wiring diagram for connection point. A switch may be
ordered with the unit if desired. It will be shipped loose
for field installation.
•
When appropriate and needed, supply and install drain
valves and vent cocks in the water system piping.
Evaporator vent cocks are factory-installed on all CICD
chillers.
•
Where specified, supply and install strainers ahead of
all pumps and control valves.
Note: CICD chillers may be ordered with cleanable,
factory-selected wye-strainers to be installed in the
field by others for protection of the brazed plate
evaporators.
•
Supply and install suitable refrigerant pressure relief
piping to the atmosphere if required. Follow ANSI/
ASHRAE 15 guidelines, relief manufacturer's
guidelines, and industry standards when working with
relief valve, fusible plugs and/or piping.
•
Start the unit under supervision of a qualified service
technician.
•
Where specified, supply and insulate the chilled water
piping as required, to prevent sweating under normal
operating conditions. Trane provides factory
insulation on evaporator and related components.

Storage
NOTICE
Store Units Above Freezing!
Store these units in a protected area above freezing
(32°F) only. Do not store outdoors with a protective
covering such as a plastic shroud. This can result in
excessive water condensation that could damage
controls and other components.
Noise Considerations
Locate the unit away from sound-sensitive areas. If
necessary, install isolators under the unit. Install vibration
isolators in all piping and use flexible electrical conduit.
Consult an acoustical engineer for critical applications.
Foundation
A base or foundation is recommended for most
installations. Provide a level surface strong enough to
support the unit. See Dimension and Weights chapter for
dimensions and weights. A flexible (isolated) concrete
foundation or footings at each loading point will reduce
transmission of vibration. Install anchor bolts in the
concrete to secure the unit.
Note: Use only anchor bolts that are flush with the top of
the foundation, not a drive in stud type. An
example of an acceptable anchor bolt is Red Head
– Multi-Set II Drop In Shell Type. Using a flush type
anchor bolt will make removal of a unit easier if
required.
If the floor is warped, uneven or in poor condition, make
necessary repairs before positioning the unit. Once the
unit is in place, it should be level within 1/8 inch side-to-side
(width) and 1/8 inch front-to-back (depth).
