Schreiber Chillers 750ACsf - Manual (Page 12)

7. Fan motors - Air-cooled only, both fan motors run when either refrigeration system
is calling for cooling. You can lower the sound level of the fan motors if you add 6'
of open duct to both fans. 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.
8. Set the temperature controllers to the desired temperature. With this temperature
set, your solid-state controller will hold this temperature. Should you need to set
temperature below 38
° F, then you must add the proper amount of industrial
antifreeze, not automotive type. Never add more antifreeze than necessary.
Antifreeze is a poor conductor of heat. It will lower the water chiller’s BTU rating.
9. With the temperature controller set on Solid State Controller, you then turn the
refrigeration manual switch to it’s on position. With temperature controller set, the
unit will control the chilled water temperature automatically.
10. 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
for more information.
