The MAC-640BH-U Drain Pan Heater prevents ice from building up on the outdoor unit base when operating in heating mode for an extended period of time in a very low temperature, high humidity condition.
Itís controlled by outdoor unit, works during the defrost operation and energizes when the outdoor temperature drops below 36° F.
Use of drain pan heaters is recommended when ambient temperatures are expected to be below freezing for periods longer than 72 hours straight; or when continuous sub-zero outdoor ambient conditions are expected to last longer than 24 hours.
