normal operating range for the refrigerant type used
in the chiller. If the low pressure gauge reading is
below normal, reduce the pressure on the spring to
provide more bypass.

3.3 INSTRUMENT / OPERATION
A. INSTRUMENT START-UP
1. When the correct electrical power and adequate water
supply pressure are supplied to the unit, it is possible to
start the unit.
2. Upon power up, the instrument displays “ChF” indicating
that the unit is in Fahrenheit temperature mode or “ChC”
indicating that it is in Celsius mode. The control then shows
the current setpoint for approximately 2 seconds before
reverting to the To Process temperature. When power is
supplied to the unit, the ON/OFF switch will illuminate.
3. PRECAUTIONS:
The chiller control is programmed from the factory with a
setpoint range of 48° to 70°F. To operate below 48°F, the
additionofinhibitedpropyleneglycolandmodicationofthe
limit control settings are required. Diligent monitoring of the
