Unit Shutdown

Unit Shutdown Procedures

Daily Unit Shutdown

Note: Refer to Start-Run Shutdown sequence in General Information Overview Sequence of Operation.

1.Press STOP.

2.After compressor and water pumps shutdown turn Pump Contactors to OFF or open pump disconnects.

Seasonal Unit Shutdown

CAUTION

Oil Pump Heater

Operation!

CONTROL POWER DISCONNECT SWITCH 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. Rinse with clean water.

5.Remove the drain and vent plugs from the condenser headers to drain the condenser. Air dry bundle of residual water.

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 qualified Trane service technicians.

Note: During extended shutdown, be sure to operate the purge unit for a 2- hour period every two weeks. This will prevent the accumulation of air and noncompensable in the machine. To start the purge, change the purge mode to ON in the DynaViewSettings Purge Menu. Remember to turn the purge mode to Adaptive after the 2-hour run time.

Trouble Analysis

If the ALARM indicator on the control panel is flashing, an MMR diagnostic has occurred. Refer to Diagnostic section for trouble shooting information. (page 35)
