17. SEASONAL START-UP OR
ANNUAL CHECK
NOTE: At the beginning of the heating season or
whenever the pool water temperature is to be raised
several degrees, the pool pump and heat pump pool
heater may need to operate continuously for several
days. During summer months, only a few hours per day
may be necessary or none at all.
1. Remove leaves, pine needles, etc., from the
evaporator coil. Clean the coil by gently applying a
mild solution of household liquid soap and water.
2. Remove the side louvered panel by removing the
single screw at the top and the two (2) screws on the
middle part of the panel. Lift and pull the bottom out.
The panel will easily come away from the cabinet
giving access to the coil for cleaning.
3. Gently rinse the coil with water; DO NOT use high
pressure.
4. Re-install the side panels and secure each with the
screws removed in Step 2.
5. Backwash or otherwise clean the pool filter. If
necessary, clean the skimmer basket and pump
strainer.
6. Set the valves to ensure proper water flow through
the unit.
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 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.
18. SUMMER SHUTDOWN
If you do not plan to use the 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
additional circulation is required. DO NOT stop all
flow through the heater.
3. IMPORTANT: Remember to reset the valves before
the next heating season, or the unit will not operate
properly.
19. 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 remove the drain plugs located in the
inlet and outlet water unions to allow water to drain.
See Figure 60.

3. Use a wet/dry vacuum or air pressure to remove
excess water, as necessary.
4. Once the water is drained, reinstall the drain plugs.
5. 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 anyway, or freeze
damage could result.
NOTE: The heater manufacturer is not responsible for
maintenance adjustments.
20. 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.
CAUTION: To clean the fins, remove the side louvered
panels and spray gently with a garden hose. DO NOT
pressure wash. Doing so will bend the fins and can void
the warranty.
