2. If condensation becomes a problem, optional drain
pans may be available from your heat pump pool
heater distributor or pool dealer.
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 serv-
ice 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 cor-
rectly.
• Is the ejected air from the unit 8°–10°F 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 ini-
tial pool heating in cold weather, it may require a
week to elevate the water temperature to a com-
fortable level. Normally, it takes about 4 days.
How many hours per day is the unit operating?
Remember that the heat pump pool heater only
operates while the pool pump is running.

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 degrees per
night compared to 4 degrees or fewer when a blan-
ket 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?
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 thermo-
stat, 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:
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 efficiency are both greater at higher ambient air
temperatures, run time should be set to take advan-
tage of all daylight hours, when the air is generally
warmer.
NOTE:
The heat pump pool heater will not run when
the
Remote
position is selected on the Pool/Spa
control and there is no remote control system
attached.
