Freezing Condition Precautions

   In areas where extended freezing conditions exist, the heater must be plumbed as
shown here (and the installation manual), so it can
be winterized.  Water left inside the heater will
freeze and cause damage.
   This plumbing setup will allow the use of pressur-
ized air to clear the heat exchanger of water in
preparation for an extended freeze. This should be
done as part of your end of swimming season win-
terizing.
   In warmer southern climates where freezing con-
ditions are temporary, you should run the water
pump 24 hours a day to prevent the water from
freezing inside the heater. Freeze damage is not
covered and may void the warranty.

Owner Maintenance & Cleaning

1.  The heat pump will produce condensation water run off while in operation. Make
sure the condensation drains in the bottom of the heater cabinet do not become blocked
with debris.  The condensation run off may attract increased plant growth and insects
in the heat pump area, be sure to keep all plants trimmed back and treat for insects as
needed.
2.  The outer air coil (located on three sides of the heater), should be kept free of
debris and buildup. A minimal air coil cleaning should be done as needed and at least
two times per year.  If the heater is installed in a sandy or salty condition, the air coil
should be cleaned more frequently.
3. To clean the air coil SHUT OFF ALL POWER, then use a garden hose at low pressure,
(without a pressure nozzle) to lightly rinse the air coil in an up and down motion.  You
can use a mild soap while rinsing to help neutralize and clean.  DO NOT spray water
directly in heater at high pressure.
4.  Cabinet surfaces can be wiped clean with a towel and mild cleaner.

Professional Maintenance

The heater should be serviced regularly like any other machine.  A factory authorized,
licensed air conditioning or mechanical contractor should perform the following main-
tenance procedures periodically.
1. Oil the fan motor.
2. Check the refrigerant charge.
3. Check the amp. draw.
4. Check all electrical supply connections & breakers.
5. Clean the air coil with approved solution.
6. Clean the interior cabinet bottom of debris.
7. Spray internal components with lubricant.
8. Inspect the installation including chemical feeder placement.
9. Inspect sprinklers to be sure the heater is not being sprayed.
10. Inspect for insect nests in and around the heat pump and treat.
