Operating Instructions
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 the water is a leak or is
condensation, there are two ways to
check this. 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.
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 the heater may not be able
to maintain your desired temperature
without the use of the pool blanket.
Seasonal Shutdowns
At the end of your swimming season
you may have freezing weather
conditions. The unions (provided) 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 (38°F for h/c units), the heater
may not operate.
Troubleshooting
Guide
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

Diagnostics
ALL MODELS (except PRO1100)
The display located on the heat pump
has diagnostic codes, which help
explain any reason for the heater not
to be operating properly. The following
are the diagnostic codes and the
reasons for them appearing:
FLO
: This code means “Pressure Switch”
or water pressure switch. This means
there is not enough water flow to
activate the water pressure switch. The
cause could be from a clogged filter or a
manual by-pass is in the wrong position
and is not allowing water into the heater.
Once the filter has been cleaned or the
by-pass has been changed to allow water
to flow through the heater, the FLO
display will go away and the water
temperature will appear on the display.
HP
: This code means “High Pressure” or
high pressure switch. Either there is low
water flow or high ambient temperature
or both. Again, the filter could be
clogged and not allowing enough water
flow to pass through the heat exchanger
and allow the heat to be taken away fast
enough, or a by-pass is not in the proper
position. Once the filter has been
cleaned or the by-pass has been re-
positioned, the display should return to
the temperature of the water.
LP
: This code means “Low Pressure” or low
pressure switch. Either the outside
ambient temperature is below 50°F (38°F
for h/c units), which is too low for the
heater to operate, or the unit is low on
refrigerant. Once the outside temperature
has risen above 60ºF, and the LP code
remains, call the factory for repair.
PSd
: This code means there is a pool sensor
defect. Please call AquaPRO
®
Systems to
arrange service for the heat pump.
DSd
: This code means there is a defrost
sensor defect. Please call AquaPRO
®
Systems to arrange service for the heat
pump.
LP3
: This is like the “LP” described
above, however the unit has shut down
because this fault has happened 3 times
within a 24 hour time period. If the
ambient temperature is below 50°F
(38°F for h/c units), the problem will
most likely persist until the ambient air
temperature rises above 50°F. Pressing
any of the buttons on the front control
panel will restore the unit to its normal
operating mode. If the ambient air
temperature is not the issue and the
heat pump continues to display “LP” or
“LP3”, please call AquaPRO
®
Systems to
arrange service for the heat pump.
HP3
: This is like the “HP” described above,
however the unit has shut down because
this fault has happened 3 times within a
24 hour time period. Please check your
pool’s plumbing, valves and pump / filter
system for blockages or flow restrictions,
as this is most likely the cause for the fault.
Pressing any of the buttons on the front
control panel will restore the unit to its
normal operating mode. If your pump and
filter system is working normally and
there are no flow restrictions and the heat
pump continues to display “HP” or “HP3”,
please call AquaPRO
®
Systems to arrange
service for the heat pump. Please note,
AquaPRO

for non-warranted service calls.
MODELS: PRO1300h/c and
PRO1300h/c TCE
COL
: This code reminds you that the
unit is running in the cooling mode.
HOT
: This means the pool temperature
has increased by 2° while the unit is
operating in the “COL” mode. This is
only a warning that the unit is having
difficulty cooling the pool to the
desired temperature. The “HOT”
message will remain until either the
pool drops to the desired temperature
or the set “COL” temperature is raised
above the pool’s current temperature.
