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 unit should start after an

approximate 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.

Please see Troubleshooting Flowcharts, following, for more detailed information.

Water Coming from the Heat Pump

Is it a leak or just condensation from normal operation? Here's how to find out.

Shut off your heat pump, leaving the pool pump running. In a couple of hours there should be a

marked reduction in the amount of water 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 to check for a water leak, you can test the water draining out the

base for the presence of the sanitizer you are using in your pool or spa. Use your water test kit,

or a test strip, to 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:

  If you are using an ionizer or ozone generator to produce sanitizer, this test method will not be

effective.

Heat Pump Running but Not 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.) If not, call AquaCal for service at 800-786-7751.

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 long are you running your circulating pump each day?

Cooler weather conditions, or heating to a higher temperature, may necessitate running the heat

pump for a longer period of time. A pool blanket can be useful in permitting shorter run times,

in turn leading to substantial energy cost savings.

What is the air temperature?

Your heat pump may be in the defrost mode if air temperatures are below 50°F. The defrost

light will be lit if the unit is defrosting. If air temperatures are not cold, but the defrost light is

still illuminated, contact AquaCal Customer Support at 800-786-7751.
