Equipment Damage!
Do not operate the unit when the oil line, liquid line service valves and all the manual shutoff
not in right position. Failure to do so may cause serious compressor damage.
3. Check the power supply voltage to the unit at the main power fused-disconnect switch.
Voltage must be within the voltage utilization range stamped on the unit nameplate. Voltage
imbalance must not exceed 2 percent.
4. Check the unit power phase to be sure that it has been installed in an "ABC" sequence.
Compressor Damage!
Failure to follow applications guidelines on electrical phase rotation may result in compressor
damage for RTXC-XE/XE-HSE unit.
5. Confirm all fans rotate freely.
6. Fill the chilled water circuits. Vent the system while water is being filled. Open the vents on the
top of the evaporator during filling and close when filling completed.
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.
7. Prove all interlock and Interconnecting Wiring Interlock and External as described in the
manual, such as water flow switch and chilled water pump interlock.
8. Start the chilled water pump to circulate of the water to vent air in the water system. Inspect
all piping for leakage and make any necessary repairs.
9. With water circulating through the system, refer to
Curves to adjust water flow and check water pressure drop through the evaporator meet
requirement of Table
10. Adjust and confirm the chilled water flow switch for proper operation.
11. Stop the chilled water pump after vent air from the water system.
12. Power on the independent 230V single phase AC power source for the evaporator heater.
Evaporator Heater Damage!
Failure to connect power after filling water or remove power before draining will result in
evaporator immersion heater failure.
