Maintenance (Continued)
If you decide to
rinse down the
evaporator coils yourself, disconnect all
power to the entire equipment pad
before you rinse it. This must be done
in order to prevent possible electrical
shock.
Condensation
All heat pump pool heaters will have
condensation. It is typical to have as
much as 6-8 gallons of condensation or
water per hour, during a warm, humid
day. Do not mistake this for a leak.
If you are not sure whether the water is
a leak or condensation, there are two
ways to check. First, use a pool test
strip to see if there is any chlorine or
bromine in the water. If there is,
contact the factory for service. Second,
you can turn off the heater, leave the
filter pump running and see if the
water stops. If you do not see
additional water, then the original
water was condensation.

CAUTION
Operating Instructions
Pool Blankets
A pool blanket has been proven to
greatly reduce the heat loss in the pool
and will save as much as 50% - 60% in
your heating bills. During the start of
the swimming season and the end of
the season, if a pool blanket is not
used, the heater may not be able to
maintain your desired temperature
without the use of the blanket.
Seasonal Shutdowns
At the end of your swimming season
you may have freezing weather
conditions. The unions (provided with
PRO1000) must be disconnected to
drain any water in the pipes. Failure to
do so may cause the heat exchanger to
expand and crack. This will void your
warranty.
If you live in an area that does not have
freezing weather conditions but are
subject to extended periods of non-use,
allow the filtration system to continue
to run water through the heater. Or
you can drain the unit of all water.
Pool Openings
If at the end of the previous season you
disconnected the unions, be sure to
connect them before you turn on the
filtration system. Once the pool has
been cleaned and the unit has been
checked for leaks, turn the power on
the heater and set the thermostat to
the desired temperature.
Note: It may take up to three days to
reach the desired temperature during
the opening of the swimming season.
Without a pool blanket, it may take
even longer and may not reach the
desired temperature until later in the
season.
Weather Conditions
Weather conditions play a big part in
the operation of the heater. Low
outside ambient temperature, high
winds, low relative humidity, and a
large amount of shading on the pool
will all have an effect on how much
time it takes to heat the pool and how
much time it might need to maintain
the desired temperature. Once the
outside ambient temperature drops
below 50ºF, the heater may not
operate.

If the heater is not operating during
the initial start-up, check to see if it has
been installed properly, per this
owner’s manual. Make sure the
breaker has been sized properly. The
following are conditions to check
before calling Aqua Pro Systems for a
service:
Unit is not running:
• Check the power light. Check to see
if the breaker is set.
• Make sure the filtration system is on
• Make sure the thermostat is higher
than the pool water temperature
• Make sure the filter is clean and is
allowing enough water to flow
• Make sure the outside ambient
temperature is higher than 50ºF
• Make sure the 5-minute time delay
has passed
• On the PRO100, make sure toggle
switch is set to pool or spa mode
and is not in the “OFF” position.
Unit is running but not heating:
• Check the air coming out of the top
of the unit. It should be
approximately 8ºF - 15ºF lower than
the surrounding ambient air
temperature. If not, call the factory
for service.
Unit runs continuously:
• Check for correct wiring.
• Lower the desired water
temperature below the pool water
temperature. If the unit is still
running, call the factory for service.
• If the unit shuts off when the
thermostat is lowered, it may be
running continuously because it
cannot reach the desired
temperature. A pool blanket may
be required to help reach this
temperature. Also, the filter pump
may need to run longer for the
heater to reach the desired
temperature.
Unit is cycling:
• Check the filters for proper water
flow.
• Check the evaporator coil for severe
frost.
• Unit could be low on refrigerant.
At this point, call the factory for
service and turn off the power to
the heater to keep the cycling from
damaging the compressor.
