Heater Strip Detail
WARNING!
This unit is frost resistant down to 0
°
F with no wind.
Prevailing winds can reduce the ability of the heater
element to prevent light freezing. If the ambient air
temperature will drop below 0
°
F, the cooler needs to
be drained of all water by blowing out all water lines,
evaporator (item 20), and the drain trap. A heater
strip is used to heat the unit and will begin to cycle
at 40
°
+/- 5
°
F. A check at this temperature will
ensure the heater is working and the unit is resis-
tant to light freezing.
ALSO, MAKE SURE THERE ARE NO PLASTIC OR
FLAMMABLE COMPONENTS DIRECTLY ABOVE
THE HEATER STRIP.
