Installation Checklist
Complete this checklist as the unit is installed and verify that all recommended proce-
dures are accomplished before the unit is started. This checklist does not replace the 
detailed instructions given in the “Installation -Mechanical” and “Installation -Electri-
cal” sections of this manual. Read both sections completely, to become familiar with 
the installation procedures, prior to beginning the work.
Receiving
Verify that the unit nameplate data corresponds to the ordering information.
Inspect the unit for shipping damage and any shortages of materials. Report any 
damage or shortage to the carrier.
Unit Location and Mounting
Inspect the location desired for installation and verify adequate service access 
clearances.
Provide drainage for evaporator water.
Remove and discard all shipping materials (cartons, etc.)
Install optional rubber isolators, if required.
Level the unit and secure it to the mounting surface.
Unit Piping
Flush all water piping before making final connections to the unit.
CAUTION
Proper Water Treatment!
The use of untreated or improperly treated water in the Unit may result 
in scaling, erosion, corrosion, algae or slime. It is recommended that the 
services of a qualified water treatment specialist be engaged to 
determine what water treatment, if any, is required. Trane assumes no 
responsibility for equipment failures which result from untreated or 
improperly treated water, or saline or brackish water. 
If using an acidic commercial flushing solution, construct a temporary 
bypass around the unit to prevent damage to internal components of the 
evaporator.
Connect the chilled water piping to the evaporator.
Install pressure gauges and shutoff valves on the chilled water inlet and outlet to 
the evaporator.
Install a water strainer in the entering chilled water line.
Install a balancing valve and flow switch (recommended) in the leaving chilled 
water line.
Install a drain with shutoff valve or a drain plug on the evaporator waterbox.
Vent the chilled water system at high points in the system piping.
Apply heat tape and insulation, as necessary, to protect all exposed piping from 
freeze-up.
