Heat Pump Running but Not Heating:
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 unrestricted airflow to operate
at peak efficiency.
How long are you running the water circulating pump each
day? Cooler climatic conditions, or heating to a higher than
typical temperature, may necessitate running the heat pump
for a longer period of time. A pool blanket may be necessary
to allow for shorter run times...not to mention significant
heating cost savings.
What is the air temperature? Your heat pump may be in
the defrost mode if air temperatures are much below 50°F.
The digital display will read “FS” or “DEF” if the unit is
defrosting or air temperatures are to cold for normal heat
pump operation.
Is the air blowing out of the top of the heater noticeably
cooler (8 to 12° is typical) than the surrounding air? If not
(after having checked the three items above), call AquaCal
Customer Suppor.
Heat Pump Not Running:
Is the display illuminated? If not, check to see if the main
breaker (located at the power supply panel) has tripped, or if
the unit disconnect switch (located near the heat pump) is off.
Reset breakers and switches to ON. In order to begin operation,
the heater’s control display must be illuminated.
Does the display read “FLO”? If so, check to be sure the
circulating pump is operating and the water filter is clean.
There may also be a valve positioned incorrectly allowing water
to bypass the heat pump.
Does the display read “OFF”? If so, depress the MODE
button until “HEA” displays. If still “OFF,” the desired
water temperature is set below 45°F. Raise the desired
water temperature above the actual water temperature;
the heater should start within 3-4 minutes.
If the display is showing any other fault code, or is blank,
contact AquaCal Customer Support.
Water Leaking out of the Heat Pump:
Is it a leak or natural condensation from normal operation?
Here’s how to find out...
Shut your heat pump off, leaving the pool pump running. In a
couple of hours, there should be a marked reduction in the
amount of water seen around the bottom of the heat pump.
If you believe the heat pump is leaking, check the water draining
from the heater for the presence of the sanitizer being used in
the pool or spa. Using your chemical test kit, check a sample
of the water for chlorine or bromine. If the sample tests positive,
call AquaCal for service. If the test is negative, the water is
probably harmless condensate. If using an ionizer or ozone
generator as a sanitizing means, the chemical test method
will not be effective in determining water leaks.
CAUTION: if testing indicates a water leak is present (water
does not dry up with the pump OFF, or there is an indication
of sanitizer in the sample taken from around the heater),
immediately shut off the water pump and contact your installing
dealer or AquaCal Customer Support for service. Permitting
the system to operate with a water leak present may damage
equipment and the pool/spa structure.
