Seasonal Unit Shutdown
CAUTION
Refrigerant in Oil Pump
Damage may occur
The control power disconnect must remain closed to allow oil sump heater operation.
Failure to do this will allow refrigerant to condense in the oil pump.
3. Open all disconnect switches except the control power disconnect switch.
4. Drain the condenser piping and cooling tower, if used.
5. To drain the condenser, remove the drain and vent plugs from the condenser
headers.
6. Once the unit is secured for winter, the maintenance procedures described under
“Annual Maintenance” in the Periodic Maintenance section of this manual should
be performed by authorized Trane service technicians.
WARNING
Refrigerant Discharge Hazard!
DO NOT ALLOW CHILLER TO INCREASE IN TEMPERATURE OR PRESSURE WHILE THE
UNIT IS OFF.
Continuous running of pumps while the chiller is off can increase the temperature or
pressure and will result in premature release of refrigerant causing bodily harm and
possible death to anyone in contact with refrigerant discharge
