Control Power Supply
Chiller is provided with control power transformer, it
is not necessary to provide additional control power
voltage to the unit.
Heater Power Supply
The evaporator shell is insulated from ambient air and
protected from freezing for temperature down to -20°C
by two thermostatically-controlled immersion heaters
combined with evaporator pumps activation through
Tracer UC800. Whenever the ambient temperature
drops below 0°C the thermostat energizes the heaters
and the Tracer UC800 activates the pumps. If ambient

CAUTION! The evaporator water pump output relay
must be used to control the chilled water pump and to
benefit from the water pump timer function at startup
and shutdown of the chiller. This is required when
the chiller is in operation under freezing conditions,
especially if the chilled water loop does not contain
glycol.
CAUTION! Refer to Freeze Protection section for
information about the evaporator circulating pump.
