Portable Chillers UGH024/1103
3-16 INSTALLATION
STOPPING THE
PLC CHILLER
To stop the chiller, press the Stop Chiller button on the control
panel.
The compressor shuts off after a pumpdown and the pump
shuts off 10 seconds later. This allows the chiller to pump
down the refrigerant system and store the refrigerant in the
receiver (water-cooled models) or condenser (air-cooled mod-
els. This prolongs the life of the compressor.
NOTE: If you want to restart the chiller immediately after
stopping it, pressing the Run arrow on the display starts the
pump (the Process Pump light on the control panel lights) but
the compressor will not turn on for three minutes. After three
minutes the compressor turns on and the Compressor light on
the control panel lights. This allows Compressors internal
temperatures to lower, making restart easier, and prolonging
the life of the compressor.
If the chiller is not working properly at any time, stop the
chiller and refer to the Troubleshooting section. If you do not
encounter any problems, proceed to the Operation section.
