Storage
If the chiller is to be stored more than one month prior to installation, observe the following pre-
cautions:
•
•
•
Note: Pressure will be approximately 20 psig if shipped with the optional nitrogen charge.
Location Requirements
Noise Considerations
•
•
•
•
•
• 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 chiller operating weight (including completed piping and full operating
charges of refrigerant, oil and water).
Refer to
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

Clearances
Provide enough space around the unit to allow the installation and maintenance personnel unre-
stricted 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 con-

Do not remove the protective coverings from the electrical panel.
Store the chiller in a dry, vibration-free, secure area.
At least every three months, attach a gauge and manually check the pressure in the refrig-
erant circuit. If the refrigerant pressure is below 71 psig at 70oF (or 46 psig at 50oF), call a
qualified service organization and the appropriate Trane sales office.

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.
Use flexible electrical conduit for final connection to the Symbio800.

Provide rubber boot type isolators for all water piping at the unit.
Provide flexible conduit for electrical connections to the unit.
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.
