General Installation Information cont.
Freeze Detection Limit (Water Flow)
Set the freeze detection limit switch SW2 #2 to "Loop" on
the printed circuit board for applications using a closed
loop antifreeze solution. On applications using an open
loop/ground water system, set to "Well" (the factory
setting). If using closed loop and no antifreeze solution
leave in "Well" position (the factory setting).
Condensate Drain
The internal condensate drain assembly consists of a drain
tube, which is attached to the drain pan, a 3/4 in. PVC
female adapter, and a flexible connecting hose. The female
adapter may exit either the front or the side of the vertical
cabinet. The adapter will be glued to the field-installed
PVC condensate piping. A condensate hose is inside all
cabinets as a trapping loop; therefore, an external trap is
not necessary.
