Unit Shutdown Procedures
CAUTION:
Compressor Damage!
To prevent damage to the compressor, be sure that all refrigerant
valves are open before starting the unit.
2. Check the oil separator oil level. See Paragraph "Oil Separator Level
Check" on Page 139 .
3. Fill the evaporator and condenser water circuits. Refer to Table 1 for evap-
orator and condenser liquid capacities. Vent the system while it is being
filled. Open the vent on the top of the evaporator and condenser during
filling and close when filling is completed.
Proper Water Treatment!
The use of untreated or improperly treated water in a CenTraVac
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.
4. Close the fused-disconnect switches that provides power to the chilled
water pump and the condenser water pump.
5. Start both the evaporator and condenser water pumps and, while water
is circulating, inspect all piping for leakage. Make any necessary repairs
before starting the unit.
6. While the water is circulating, adjust the water flows and check the water
pressure drops through the evaporator and the condenser. Refer to
“Water System Flow Rates” and “Water System Pressure Drop”.
7. Adjust the flow switch on the evaporator piping and condenser piping (if
installed) for proper operation.
8. Stop both water pumps. The unit is now ready for start-up as described in
“Start-Up Procedures”.
