ON/OFF Switch
Location: The chiller has a rocker ON/OFF switch located on the front of the chiller.
Operation: Toggle the switch to the ON position (I) to make the chiller run. Toggle the switch to the
OFF position (O) to make the chiller stop. If a fault occurs, toggling the switch to OFF and then back
ON will reset the fault.
ON/OFF switch, OFF position
Notes: Electrical power must be applied to the chiller at least 12 hours in advance of turning the unit
on. This energizes the crankcase heater and drives out any accumulated liquid refrigerant in the
compressor.
If unable to energize for the full 12 hours, energize for a minimum of 1 hour, switch the unit ON and
wait until the compressor starts. Cycle the unit OFF and ON 3 to 4 times before leaving the unit
switched ON.
