Installation Procedures
UNIT INSPECTION
Inspect your unit very carefully before
installing. Make sure there has been no
damage to the evaporator fins or there
are no punctures or oil-soaked areas on
the box. This would indicate damage
to the refrigeration system and should
be rejected immediately.
Please read and save these instructions. Read carefully before attempting to assemble, install, operate or maintain the product described.
Protect yourself and others by observing all safety information. Failure to comply with instructions could result in personal injury and/or
property damage! Retain instructions for future reference.
Operating Instructions
Heat Pump Pool and Spa Heater

THE UNIT MUST BE TRANSPORTED IN THE UP-
RIGHT POSITION AT ALL TIMES AND MUST
NOT BE DROPPED OR TAILGATED. DAMAGE
TO THE UNIT DURING TRANSPORTATION
IS NOT THE RESPONSIBILITY OF THE
MANUFACTURER. IF UNIT IS CLOSER THAN
18 INCHES, THE MANUFACTURER IS NOT
RESPONSIBLE FOR BAD, WORN OR SEIZED
FAN MOTORS AND CAPACITORS.
It is the homeowner’s responsibility
to remove any obstructions, at their
own cost, before any scheduled
maintenance work is performed. If not
done, the homeowner is responsible
for any additional cost of fees and, if
not paid, the the warranty will be void.
UNIT LOCATION
Once the unit has been inspected and
cleared of any transportation damage,
it is now time to locate the pool heater.
It is very important to understand
the location of the unit for the best
performance of operation. See Figure 1
for location recommendations.
If unit is closer
than 18 inches, the
manufacturer is not responsible for bad,
worn or seized fan motors and capacitors.
A minimum of 18 inches of clearance
between the evaporator coils and shrubs,
fences, walls, etc. must be maintained
for adequate air intake. A minimum of
5 feet of vertical clearance between the
top of the unit and any roof overhang or
other obstructions must be maintained in
order to prevent the re-circulation of cold
air back into the evaporator coils. This
is to maintain the efficiency of the unit.
A minimum of 36 inches of clearance
between the front of the unit (access
panel area) and any obstruction must
be maintained to allow maintenance
on the unit when necessary. The unit
must be located on a solid level surface,
a minimum of 36 inches x 36 inches for
proper drainage. Make sure any sprinkler
heads are not directly spraying water on
the unit. While heat pumps are made
for an outdoor environment, they are
not designed to have sprinkler water
constantly spraying them.
NOTE: This type of constant watering
directly on the unit can void your
warranty.
Condensation drain holes are provided
in all units for adequate removal of
condensation and rainwater. ALL
UNITS WILL HAVE CONDENSATION.
THIS SHOULD NOT BE MISTAKEN FOR
A LEAK IN THE UNIT.
PLUMBING
Where freezing
weather is
encountered, the detachable
connection/union (provided) must
be installed immediately adjacent to
the heater to facilitate servicing and
draining of the heat exchanger.
Draining is necessary to prevent
damage to the condenser shell and coil
due to the expansion of freezing water.
For proper winterizing, drain all water
by blowing any remaining water
through the inlet and outlet with low
pressure high volume air flow as in
using a wet/dry vac in reverse.
The minimum water circulation capacity
flowing through the pool heater is
25 gallons per minute. The water
capacity is 80 gallons per minute on all
models. Intentional setting of the
water FLow outside of these
guidelines will void the warranty.
Do not install a water shutoff valve in
the piping from the outlet of the pool
heater to the pool or tub. However,
a check valve that does not include a
shut-off feature may be installed for
convenience during servicing.
A check valve or Hartford Loop is
required between the unit and a
chlorinator. The chlorinator must be
downstream of the heat pump. Failure
to do so may void the warranty.
If you have an in-floor cleaning
system, please take note of any special
plumbing requirements to operate all
units effectively.
Figure 2 shows the recommended
installation layout.
NOTE: Do not place chlorine tablets,
or any other chemicals directly in
skimmer basket. Doing this will void
the warranty.
ELECTRICAL CONNECTIONS
All wiring and
electrical connections
must be performed by a qualified
electrician. Installations must be in
accordance with local and national codes.

HIGH TEMPERATURE LOCK OUT
Your heat pump includes a special
feature to “lock” the high temperature
settings. This eliminates the need for a
thermostat lock-box. This prevents
unauthorized persons from adjusting
the heat pump above these desired
limits. To activate this feature, please
call  during business hours
8 AM to 5 PM EDT Monday through
Friday and we will be glad to assist in
setting up this feature.
FEATURES
All applicable features to these models
have been covered in the previous
sections. Other models’ features are
discussed in designated sections,
subsequent to this section.

Controls
TOGGLING BETWEEN HEATING AND
COOLING MODE
The unit will default to the heating
mode. If the cooling mode is desired,
press the SET button until the H-C
screen is displayed. Then press
the arrow buttons until “COL” is
displayed on the screen. This puts the
unit into cooling mode. The water
temperature set point will now be
the water temperature that the unit
is cooling the water to. When the
unit is in cooling mode, the screen
will flash between the current water
temperature and “COL” to remind the
user that cooling mode is activated.
DEFROST CYCLE
Your h/c unit is capable of keeping
your pool warm in very cool
temperatures. Most pool heaters
will not operate below 50°F. Your
h/c unit will work down to 38°F by
utilizing a “defrost cycle”. It does this
automatically by sensing the coolant
temperature and reversing operation
for 2 minutes to defrost the evaporator
coil and will resume heating function
after defrosting the evaporator coil.
SELECTING FUNCTIONALITY OF UNIT
This unit is capable of operating as a
Time Clock Override (TCO) or as the
Time Clock Eliminator (TCE). If you
already have a time clock on your
swimming pool and would like to
maintain its normal operation with
the added benefit of a heat pump
time clock override – please review the
section for the Time Clock Override. If
you do not own a time clock for your
pool system - please review the section
for the Time Clock Eliminator.
TIME CLOCK ELIMINATOR (TCE)
OPERATION
Please read the functions of this
feature carefully.
All wiring and
electrical connections
must be performed by a qualified
electrician. Installation must be in
accordance with local and national codes.
This section allows you to run the heat
pump at set intervals during the day. If
you have a time clock, and would like
to use it please refer to the Time Clock
Override section.
For the TCE feature to work, your pool
pump must be wired to the heat pump

will run the system the desired hours
each day and spread the time out

makes for better filter operation
and allows the heater to update the
water temperature 6 times per day.

will continue to run the system until
the desired temperature is met. If
the amount of run time exceeds a
period’s run time, the excess time
will be subtracted from the next
run period(s). Please note that
on cold and / or windy days, the
unit could run for long times to
generate and maintain the desired
pool temperature. Please see the
“application” section about “pool
blankets” to help maintain your
pool’s temperature.
t 5IFUJNJOHGVODUJPOCVJMUJOUP
the TCE will always run the heat
pump for 15 minutes every 4
hours to determine if more heat
is needed to maintain the pool’s
desired temperature - even if all
of the available run time was used
in previous cycles. This provides a
couple of added benefits. Pools will
lose most of their heat at night if left
uncovered, however, since the unit is
checking for and adding heat when
needed, it prevents long recovery
times when compared to non-TCE
units. The other benefit is that some
states and electric utility companies
offer a discount for off-peak usage
of electricity. Please contact your
electricity provider if you have
questions.
t &YBNQMFPG5$&PQFSBUJPOoZPV
require the system to run for 12
hours to meet your pool filtering
needs. This means for each of the
6 periods, the heater will run the
system for 2 hours and then turn off
for 2 hours. If the system needed
to run for 3 hours in one of the
periods to reach the desired pool
temperature, the next period would
be 1 hour on and 3 hours off unless
additional heating is needed. The
cycle continues for 6 periods and
renews at the end of each 24 hours.

push the “SET” button repeatedly
until “FIL” displays. Then using the
“up” and “down” arrows, you can
select how many total hours a day
you want the system to run for your
pump and filtration needs. The
range of hours is “off” to 2, 3, 4,…
up to 23 hours to “on”. As described
before, the run time will then be
calculated and spread out over the 6
time periods for 24 hours. Selecting
the “on” position will run the pump
and filter system continuously. The
unit leaves the factory with the “FIL”
mode set to “OFF”.
TIME CLOCK OVERRIDE (TCO)
OPERATION
All wiring and
electrical connections
must be performed by a qualified
electrician. Installation must be in
accordance with local and national codes.
This section allows you the option of
using an existing time clock with the
heat pump. If you do not have a time
clock, please refer back to the Time
Clock Eliminator section.
The pump must be connected to the
heat pump and also the time clock for
the Time Clock Override feature to
work correctly. See figure 4 on page 5
for the optional TCO wiring schematic
and electrical connections.

position. You will need to set the
heat pump’s hours of run time in
the “FIL” mode to “2” hours. See
“activating and setting system run
time” below to set the run time.
Leave your time clock set to the
desired pump and filter operation
time. This will enable the heat pump
and filter system to run the desired
hours of the day and also provide the
benefit of checking if heat is needed
every 4 hours. It will do this by
running the pump and filter system
for 15 minutes. If heat is needed, it
will continue to run until the pool
has reached the set temperature. If
no heat is needed, the system will
turn off and continue checking for
heat every 4 hours. This provides a
couple of added benefits. Pools will
lose most of their heat at night if left
uncovered, however, since the unit is

Guidelines (All Models)
MAINTENANCE
All heat pumps are designed
for outdoor use. However, some
maintenance is required to maintain
the full life of the heater and is
necessary to maintain your warranty.
Annual maintenance should be
scheduled to make sure blowing sand
or falling debris is removed from the
inside of the heater.
Rinsing the coil down, monthly, with
low water pressure will help keep
the base of the unit clear of debris
is a must. Do not use a high pressure
washer. This can cause damage to
your evaporator coils and will void
your warranty. It is recommended
that a licensed air conditioning
specialist perform the annual planned
maintenance on your heater.
To maintain a valid warranty, a
record of annual maintenance
must be kept and provided when
redeeming the warranty.
Annual maintenance includes cleaning
the coils, compressors, filters. Clean
all rust from the compressor and filter
drier then coat it with a layer of paint.
THE WARRANTY DOES NOT COVER
FAILURE FROM RUST. The unit must
be rinsed once a month with CLEAN,
LOW-PRESSURE water.
The warranty will cover corrosion if you
live within 10 miles of a body of Salt Water
and only if there is a record showing that
the unit was sprayed monthly.
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 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% - 80% 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. Clear water by blowing air in
the inlet and outlet using a wet/dry vac
in reverse. Failure to do so may cause
the heat exchanger to expand and
crack and will void your warranty. Once
water has drained, reconnect the pipes
to keep debris out of the system.
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 all other units
with a digital control board), 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 for a
service:
DIAGNOSTICS
Most Models (excluding  & HC
units in cooling mode)
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 pressure 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.
FL3: This code means that water flow
was lost 3 times within 24 hours or unit is
programmed wrong. Call 1-
for assistance. Check the system for flow
obstructions or contact us at
1- for assistance.
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 all other units with a Digital Control
Board), 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 to arrange service for
the heat pump.
DSd: This code means there is a defrost
sensor defect. Please call 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 all other units with a
digital control board), 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 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 to arrange service
for the heat pump. Please note, we will
not be responsible for non-warranted
service calls.

COL: This code reminds you that the
unit is running in the cooling mode.
LP: If in “cooling mode”, this code may
indicate that there is not enough water
flow
HP: If in “cooling mode”, this code may
indicate that an external coil is blocked
or that there is recirculated air.
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.
