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.
Figure 9. Drain Plugs Locations
3. Use a wet/dry vac 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 any- way, 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.
Air Coil Cleaning
Efficient operation depends on free circulation of air
through the thin and tightly-spaced fins of the evaporator
coil(s). The evaporator must be cleaned whenever it has a
buildup of dirt or debris.
Cabinet Care (optional)
A
WARNING:
Shut OFF electricity to the unit before
cleaning.
The powder coated 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. See
Figure 10
for condensate drain hole
locations.
2. If condensation becomes a problem, optional drain
pans may be available from your heat pump pool
heater distributor or pool dealer.
