TROUBLESHOOTING

Common Troubleshooting Issues

Heat Pump Not Running

Is the power light lit?

If not, ensure the main breaker (located at the power supply panel) and the disconnect switch (located near the heat pump) are both turned ON.

Is the flow light lit?

If not, check to be sure that the circulating pump is operating and the filter is clean. There may also be a valve positioned incorrectly allowing water to bypass the heat pump. Be sure water is flowing through the heater.

Is the Pool or Spa thermostat selected, and have you tried turning the selected thermostat to a higher temperature setting?

If not, the actual water temperature may be above that of the selected thermostat. Raise the desired water temperature above the actual water temperature; the heater should start after an approximate five (5) minute delay. If the heat pump still fails to start, and the unit is not in defrost (defrost light lit), contact AquaCal Customer Support: 800-786-7751.

Heat Pump Running but Not Heating

Is the air blowing out of the top of the unit noticeably cooler than the surrounding air?

(A9°F to 12°F difference is typical.) If not, contact AquaCal for service at: 800-786-7751. But first, be sure all air coil surfaces are free from obstructions– low 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 temperature, may necessitate running the heat pump for a longer period of time. Was the heater sized considering the use of a solar blanket (check with installing dealer)? A blanket can be useful in permitting shorter run times, in turn leading to substantial energy cost savings.

What is the air temperature?

The heat pump may be in the defrost mode if air temperatures are below 50°F. The defrost light will be lit if the heater is defrosting. If air temperatures are not cold, but the defrost light is still illuminated, contact AquaCal Customer Support at: 800-786-7751.

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.

Or, as an alternate method, test the water draining out the heater base for the presence of the sanitizer being used in the pool or spa. Using a water test kit, or a test strip, check a sample of the water for chlorine or bromine. If the sample tests positive for sanitizer, call AquaCal for service at: 800-786-7751. If the test is negative, the water is probably harmless condensate.

NOTE: The water test method will not be effective if an ionizer or ozone generator is being used to produce the sanitizing agent.
