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-
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.
4. Set the valves to ensure proper water flow through
the unit.
Summer Shutdown
If you do not plan to use the heat pump pool heater
during the summer months, secure and protect it as
follows:
1. Turn the unit circuit breaker or disconnect switch to
OFF.
2. Leave the valves set the way they are unless addi-
tional circulation is required. DO NOT stop all flow
through the heat pump pool heater.
3. IMPORTANT: Remember to reset the valves
before the next heating season, or the unit will not
operate properly.
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.
N
OTE: If the pool pump and heat pump pool heater
shut OFF before the water temperature is raised to
t
he 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 heat pump
p
ool heater capacity 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 generally warmer.
Continuous Pump Operation
I
t 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
p
ower failure occurs, the unit MUST be drained any-
way, or freeze damage could result.
