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 resistant to light
freezing.
ALSO, MAKE SURE THERE ARE NO PLASTIC OR
FLAMMABLE COMPONENTS DIRECTLY ABOVE
THE HEATER STRIP.
