Fill the chilled water tank through the hose bib which is located on the chilled water
return line. Fill the tank until it reaches the level as marked on the water sight glass.
The water level should be kept within 1" of the marked level. Do not fill the water
tank with deionized water.
Check the voltage on the chiller to see that it matches your supply. When applying
power to the water pump (by turning the manual switch on), make sure all the
switches on the control panel are in the "off" position. It is necessary to check the
rotation of the water pump. The motors on all pumps have an internal overload
protection.
Power to the unit should be on for 3 hours prior to full usage to allow the crank
case heater to heat the compressor. PLEASE READ SECTION ON CRANK CASE
HEATER ON PAGE 18.
The water pump manual switch controls the operation of the water pump. After
checking the rotation of the water pump. PLEASE NOTE when the water pump is
turning the proper rotation. The water pump switch must be on in order to check
rotation of fan motor. The refrigeration system will not run unless the water pump
switch is in the on position. Set the temperature controller to the desired
temperature. If the temperature is set below 36
0 F, antifreeze must be added to the
water supply tank. Use a non-automotive antifreeze which can be added through
the overflow pipe. Never add more antifreeze than necessary, since it is a poor
conductor of heat the cooling capacity of the chiller will be reduced.

With the temperature controller set, the compressor can be turned on by the
manual switch. The refrigeration system is now running. It should be noted that
there could be a two to three degree difference between the temperature control
setting and the dial thermometer. Use the dial thermometer as a guide. Once set,
the temperature controller will control the temperature of the water automatically.
This unit is not weatherproof and should not be installed outdoors. Outdoor
installation is possible in some areas of the country. Please check with the factory
