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
and 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.
