General Installation Information
•
Please read and take heed of the water piping system
flushing procedure and water treatment requirements
found in
"Appendix B," p. 55
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).
