HEAT PUMP FAILS TO OPERATE...
Is the display illuminated?
Is the green light illuminated? If not, ensure the breaker is turned ON. The red light illuminates when the unit runs
only (fan, compressor, etc.)
HEAT PUMP RUNNING...BUT IS IT HEATING?
Is the air blowing out of the top of the unit noticeably cooler than the surrounding air?
(A 9°F to 12°F difference is typical.) Be sure all air coil surfaces are free from obstructions (roof overhangs,
landscaping, walls, fences, etc., can restrict air flow). The heat pump needs good airflow to operate at peak
efficiency.
How many hours/day does the circulating pump operate?
Cooler weather conditions, or heating to a higher than normal, may necessitate running the heat pump for a longer
period of time. Was the heater sized considering the use of pool blanket? A blanket can be useful in permitting
shorter run times, in turn leading to substantial energy cost savings.
What it the air outside temperature?
The heat pump may be in the defrost mode if air temperature are below 50°F or if the water temperature is around
77°F. If the heater is in defrost, the code “FS” will be displayed. If air temperature are not cold, but the heater
remains in defrost, contact your retailer.
WATER COMING FROM THE HEAT PUMP...
Is it a leak or just condensation from normal operation? Here's how to find out.
Shut the heat pump off, leaving the circulation pump running. Within a few hours, there should be a marked
reduction in the amount of water seen around the bottom of the heat pump. If the water appears to be drying up,
the water is probably harmless condensate, indicative of normal operation.
