21. TROUBLESHOOTING
If your unit does not operate, or simply does not heat your
pool water, Fault Messages on the front control panel can
provide valuable clues as to what is wrong, and may even
indicate precisely what the problem is. Always observe
these messages before calling a service representative.
By reporting on the telephone the Fault Messages that are
showing, the service rep may be able to solve the problem
without the expense of a service call.
A. Unit Is Running, But Not Heating
• Is water flow through the unit adequate? Check the
unit for obstructions, such as a clogged filter pump
strainer, a dirty filter, or valves not positioned correctly.
• Is the ejected air from the unit 8°–10°F (4.4C–5.5C)
cooler than incoming air? If so, the unit is extracting
heat from the air and transferring it to the pool.
• Is water condensing on the evaporator and internal
copper pipes? This is also evidence of heat removal
from the air. When the air is cool with low humidity,
condensation may not be evident.
• How long has the unit been operating? During initial
pool heating in cold weather, it may require a week to
elevate the water temperature to a comfortable level.
Normally, it takes about 4 days.
• How many hours per day is the unit operating?
Remember that the heater only operates while
the pool pump is running. Set the time clock to
permit 24 hour per day operation. After the desired
temperature is reached, return the unit to normal
operation of 8–10 hours per day.
• 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? Unblanketed
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 pool pump and heat pump pool heater shut
OFF before the water temperature is raised to the desired
level, you must lengthen the running time of both. To do
this, reset the time clock dial for the longer running time,
or manually operate the pump with the timer override
switch. Since the unit capacity and eciency are both
greater at higher ambient air temperatures, 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 5-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 5-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 conrm there is
no chlorine in the water.
