Cabinet Care (optional)
The stainless steel cabinet is designed for harsh out-
door 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.
Troubleshooting
If your unit does not operate, or simply does not heat
your pool water, Fault Codes 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 codes before calling a service
representative. By reporting on the telephone the Fault
Codes 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. Check the operation of the flow
switch.
• Is the ejected air from the unit 8°–10°F
(4.5°–5.6°C) 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.
WARNING:
Shut OFF electricity to the unit before
cleaning.
Freeze Protection
If the unit is installed in a location subject to freezing
conditions, it is important to protect the water circuit
from freezing, just as should be done for the pump and
filter.
System Drain-Down
1. Turn the unit circuit breaker or disconnect switch
to OFF.
2. With the pool pump OFF, close the external shut-
off valves and loosen the inlet and outlet water
unions to allow water to drain. Use a Wet/Dry Vac
or air pressure to remove excess water.
3. Loosely re-attach the unions.
4. Cover the unit with a waterproof cover.
Continuous Pump Operation
It is also possible in some areas to prevent unit freeze
damage by operating the pump continuously during
freezing weather. However, this results in significantly
higher pump operating costs. Further, if a sustained
power failure occurs, the unit MUST be drained any-
way, or freeze damage could result.
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.
NOTE:
The heat pump pool heater MANUFACTUR-
ER 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.
