order to check rotation of fan motor. The refrigeration system will not run unless the
water pump switch is in the on position.
7. Set the thermostat to control the desired temperature. Caution: Never set
temperature of chilled water below 38 ° F unless you add industrial type antifreeze.
No automotive type. Do not add more antifreeze than necessary. It does lower the
BTU rating. DO NOT SET TEMPERATURE BELOW 30
° F or over 80° F.

installation is possible in some areas of the country. Please check with the factory

INSTRUCTION FOR TEMPERATURE CONTROL
Please note the dial thermometer and thermostat are both an indicator of the chilled
water temperature. You will not necessary find the both to read the same temperature.
They are installed in a copper weld at the bottom of the chilled reservoir. We consider
the thermostat as the true chilled water temperature. This is the controller for cycling the
refrigeration system off and on.
NOTE: You can adjust the dial thermometer if you find it necessary. You do this by
removing the lens. The lens is removable by prying gently on the lens. Then with the
lens out you hold the pointer with one hand and turn the center knob. You then turn the
center pointer counter clockwise to lower and clockwise to raise the temperature. You
need not turn this knob too far. A slight turn will change its temperature enough.
The dial thermometer should be set at the time the thermostat is cycling unit off. If you
do not care to make this change, it is important you let those operating the processing
equipment be aware that there will be a difference between the thermostat and the dial
thermometer. We recommend you note any difference between the thermostat and the
dial thermometer.
