•
Is airflow through the unit being obstructed?
Restrictions such as shrubbery, tall grass, dirty
coils, or any other obstruction to airflow will reduce
performance.
•
Is the pool blanket/cover being used? Uncovered
pools can lose up to 10°F (5.5°C) per night compared
to 4°F (2.2°C) or fewer when a blanket is used.
Without a blanket, the total heat gained during the
day can be lost overnight.
•
Are rapid heat losses occurring in some other way,
such as high-wind, spillage, rainfall, flow through
solar panels at night, or a high water table?
NOTE: If the heat pump pool heater shuts off before
the water temperature is raised to the desired level,
you must increase the running time. To do this, reset
the time clock dial for a longer running time or manually
operate the pump with the timer override switch. Since
the unit capacity and efficiency are greater at higher
ambient air temperatures, the run time should be set
to take advantage of all daylight hours when the air is
generally warmer.
B. Unit Is Not Running
•
Is the temperature display ON? If not, the circuit
breaker may be shut OFF or tripped. Reset the
breaker by switching it OFF, and then back ON.
Verify that the breaker is set and operating properly
before calling for service.
•
Are the Pool/Spa settings correct? Verify that
the temperature has been properly set on the
thermostat, and that it is higher than the current
water temperature.
•
Have you waited approximately 3-minutes for the
time delay? After the unit has been running and
then shut OFF for any reason, there is a delay
before operation can begin again. The display will
read "Comp Start Delay" when this 3-minute delay
is active.
NOTE: The heater will not run when the Remote
position is selected on the pool/spa control and there is
no remote control system attached.
C. Condensation Seems Excessive
Heat pump pool heaters can produce a large amount of
condensation (water) during operation. If you suspect that
the unit is leaking:
•
Shut the unit OFF and leave the filter pump running
to see if the water stops dripping. If the water stops
dripping, the unit is not leaking.
NOTE: Use a pool chemistry test kit to confirm there is
no chlorine in the water.

22. SERVICE CALL
VERIFICATION
NOTE: The Service number is located on the front of the
heater at the brand label.
Before you make a service call, first determine if the
problem is:
•
Warranty Service - must have model number,
serial number and date of installation or Warranty
Registration confirmation number.
•
Unit operation (power supply, water flow, or time
clock adjustment).
NOTE: The manufacturer is not responsible for these
adjustments.
Power Supply
•
Verify that all circuit breakers are reset and working
properly.
•
If the temperature display on the control panel still
does not light, contact the installing dealer, since it
may be a power problem requiring an electrician.
Water Flow
•
Verify that the pool filter is clean to provide good flow.
•
Verify that valves are properly positioned to allow
adequate water flow through the unit.
Time Clock Adjustment
Verify that the time clock is set to permit the unit to run
long enough to heat properly.
Set Factory Defaults
If programming is disarranged and no operation can
reliably be made, the control board can be reset to Factory
Default values. This operation changes all adjustable
settings to factory default settings.
NOTE: Previous settings will be erased and are no
longer recoverable. All settings will have to be re-entered
by hand to re-establish proper operation.
After setting the factory defaults, check the Program,
Installer, and Schedule menus as necessary to configure
the desired operation settings and optional controls.
