Installation Mechanical
Unit Storage
Extended storage of the chiller prior to installation requires the following
precautionary measures:
1. Do not remove the protective coverings from the control panel.
2. Store the chiller in a dry, vibration-free and secure area.
Periodically check the pressure in each refrigerant circuit to verify that the refrigerant
charge is intact. If it is not, contact a qualified service organization and the appropriate
Trane sales office.
Location Requirement
Noise Consideration
Locate the unit away from sound-sensitive areas. If necessary, install the optional
isolators under the unit. Refer to “Unit Isolators”. Install vibration isolators in all piping
and use flexible electrical conduit. 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 operation weight (i.e. including completed
piping, and full operating charges of refrigerant, oil and water). The unit operating
weights are provided in Table 3 and Table 4. Once in place, the chiller should be level
within 1/4” (6.3 mm) over the length and width. The Trane Company is not
responsible for equipment problems resulting from an improperly designed or
constructed foundation or for improper installation.
Ventilation
Make provisions to remove heat generated by unit operation from the equipment
room. Ventilation must be adequate to maintain an ambient temperature lower than
125 F (52.5 C). The condenser and evaporator pressure relief valve(s) must be vented
in accordance with all local and national codes. Refer to “Pressure Relief Valves”.
Drainage
Locate the units near a large capacity drain so that water vessels can be emptied
during shut down or repairs. Condensers and evaporators are provided with drain
connections. Refer to “Unit Piping”. All local and national codes apply.
Rigging
Model CGWF/CCAF chillers should be moved by lifting, if the crate has been
removed. Refer to Table 3 and Table 4 for typical unit lifting and operating weights.
Figure 4 and Figure 5 show proper lifting methods. When on the shipping skid, the
unit can be pushed from one end with a forklift, but should never be lifted using a
forklift.
Note: Two steel lifting angles, to be used for lifting the unit, are secured to the skid
when the unit is shipped (20 -50 ton units only). Hardware is provided to mount the
lifting angles on the unit.
