WARNING: Initial startup
Do not press any buttons after initially applying
power to the Chiller. Let the Chiller set, undis-
turbed, for a minimum of 8 hours before starting
the Chiller. This is necessary to allow the
crankcase heater to warm properly, and to pre-
vent the refrigerant from pooling in the com-
pressor.
After the initial 8-hour minimum warmup, continue with start-
up:
Press the Start Chiller button.
Check the Pump and Compressor lights on the control
panel; they should turn on and off as the pump and com-
pressor cycle on and off. The To Process temperature dis-
plays on the control. The To Process temperature is real-
time temperature. It should change as the chiller runs and
cools the fluid.
Check the rotation of the pump.
If pump is not turning, disconnect main power to chiller,
swap any two incoming power wires; reapply main power.
Check for leaks inside the chiller cabinet; fix any leaks
and dry the inside of the chiller before proceeding.
Check the compressor.
If the compressor is running backwards, disconnect the
Chiller from the main power supply, switch any two
incoming main power leads, and reapply main power sup-
ply. Wait three minutes. The compressor should now be
running in the proper direction.
Check the sight glass on the back of the chiller.
If the fluid level is low, follow the steps to add fluid. See
Filling the Chiller in the Installation section.
If the chiller is not working properly at any time, press the red
Stop button to turn off the chiller.
When the compressor is shut
off it cannot be turned on
again for three minutes. This
allows temperatures and
pressure in the chiller to
equalize, making restart easi-
er, and prolonging the life of
the chiller.
