Troubleshooting
If your unit does not operate, or simply does not heat
y
our pool water, Fault Codes (digital models), or the
indicator lamps (analog models) on the front control
p
anel, can provide valuable clues as to what is wrong,
and may even indicate precisely what the problem is.
Always observe these codes (or lamps) before calling
a service representative. By reporting on the tele-
phone the Fault Codes (or which lamps are ON or
OFF) 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 posi-
tioned correctly.
• 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 inter-
nal 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. 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
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 capaci-
ty and efficiency are both greater at higher ambient
air temperatures, run time should be set to take
advantage of all daylight hours, when the air is gen-
erally warmer.
Maintenance
The following maintenance procedures are designed
to keep your unit operating at a high level of reliability.
Maintenance must be performed on a periodic
basis to maintain warranty coverage and prevent
system failures and performance degradation.
Air Coil Cleaning
Efficient operation depends on free circulation of air
through the thin and tightly-spaced fins of the evapo-
rator coil(s). The evaporator must be cleaned
whenever it has a buildup of dirt or debris.
Cabinet Care (optional)
The cabinet is designed for outdoor use and requires
little care. However, you can clean it if you wish.
Wash the cabinet with soap and water.
Unplug Condensation Drain Holes
The unit extracts humidity from the air as it passes
through the coil, similar to the way a cold drink outside
“sweats” on a hot day. This condensation drains from
the bottom of the unit.
1. Routinely check to be sure the condensation drain
holes in the base of the unit are not plugged with
dirt or debris.
2. If condensation becomes a problem, optional drain
pans are available from your heat pump pool
heater distributor or pool dealer.
WARNING: Shut OFF electricity to the unit before
cleaning.
NOTE: The heat pump pool heater MANUFACTUR-
E
R IS NOT RESPONSIBLE for maintenance
adjustments.
CAUTION: To clean the fins, spray gently with a
garden hose. DO NOT pressure wash. Doing so
will bend the fins and can void the warranty.
