STOPPING
THE
CHILLER
Press the Stop/Start Chiller button.
Check the Pump and Compressor lights on the control panel;
they should turn on and off as the pump and compressor cycle
on and off. The To Process temperature displays on the con-
trol, and is the real-time temperature. It should change as the
chiller runs and cools the fluid. This is what the chiller con-
trols.
To safely stop the chiller at any time, press the Stop/Start
Chiller button on the control panel. The compressor should
stop immediately but the pump runs for 2.5 seconds.
The chiller remains on, but stopped. The display screen on the
control remains on.
NOTE: When you press the Stop/Start Chiller button, the
pump and compressor both stop. If you want to restart imme-
diately by pressing the Stop/Start Chiller button, the pump
will turn on but the compressor will not turn on for three min-
utes. The Process Pump light on the control panel will light
immediately. After three minutes the compressor turns on and
the Compressor light on the control panel lights.
