HEAT PUMP EFFICIENCY
Your new highly efficient heat pump pool/spa heater
will deliver warm pool water for your comfort for pennies a day. For every dollar you spend to run your heat
pump, you will receive between $4.00 and $5.00 worth
of heat in return. The heat pump transfers the heat from
the outside air to your pool or spa. Your heat pump
costs about 60 to 75 percent less than L.P. Gas heaters
to operate with less maintenance and gas storage tank
is not needed. Your heat pump produces no pollution
and no pilot lights to deal with.
$2.34
Cost Per 100,000 Btu's of Heat
$1.65
Approximate
RETURN ON INVESTMENT
The costs of installing a heat pump are somewhat higher
than a gas heater but you will save enough in operational costs to offset the difference, probably in the first
year or two. After a few heating seasons you will have
saved enough, compared to LP gas heat, to pay for the
entire heat pump and installation
.
LONGER SWIMMING SEASON
A heat pump is the least expensive way to heat your
pool. It will out perform solar by delivering heat on
demand, no matter how much sunshine is available. A
solar system with a gas back L.P. Gas back up will cost
more to operate than the heat pump alone.
In Florida, a heat pump offers a full 12 months of swimming season compared to a solar systems 10 month
swimming season. A heat pump will provide higher
temperatures than a solar system. Solar will not heat a
spa on demand after sundown & during inclement
weather.

DUAL THERMOSTAT CONTROL PANEL
THERMOSTAT
The thermostat dial is just like any other,
when you set it at a certain setting the
heater will heat up to that temperature
and then shut off. When the pool/spa water temperature drops below this setting
the heater will come on and start heating
the water back up to the setting on the
thermostat.
You will notice there are no number settings printed on the dial face. There is a
certain procedure to follow to determine
the exact temperature you have the thermostat set at. This is described further
on next pages.
The maximum setting for a thermostat is
104 degrees F. You will only be able to
reach this high temperature in a spa application. Pool temperatures are normally between 78 and 82 degrees F. Actual pool temperatures are determined by
your installer, when the unit is sized to
your specifications. The lowest setting
on the thermostat is around 60 degrees F.
To disable the heater, turn the thermostat dial all the way to the left. If you
live in a climate where the water temperature may drop below 60 degrees F
you must shut the circuit breaker off.
Otherwise do not use the breaker as an
on/off switch.
See "Start up Procedures" regarding
compressor preheating if the main power
breaker is shut off. The compressor must
be preheated for 8 hours after the power
supply has been disconnected.
L.E.D. STATUS LIGHT PANEL
The indicator lights will help you determine that the unit is running
normally or if there is a condition that may keep the heater from
running. Note that the spa light is inactive on single thermostat
units. See next page for details on reading the status lights.
L.E.D. Status Lights
( See page 7 for details.)
DUAL Thermostat
regarding water flow. When this light is off the heater will not run.
Control Ready "Green": The green control ready indicator light lets you know that the heater has power and it
is ready to heat. This light must be on before the heater can run. If this light is off, check you power supply and
circuit breakers. If this light is off, none of the others will light either.
L.E.D. STATUS LIGHT PANEL
The unit may still have "live voltage" when the control light is off.
NOTE: The bottom four indicator lights work in sequence from left to right.
SPA MODE "Orange": The orange spa mode indicator light tells you that you have selected the spa mode
with the pool spa select switch, (dual thermostat control only). This light will be inactive when used with the
standard single thermostat control (pool only).WATER PRESS. OK "Green": The green water pressure OK
indicator light tells you that the internal water pressure switch is OK. The internal water pressure switch is used
to shut the heater on and off with the circulation pump. The heater should not run when the water pump is not
pumping water through the heater. Dirty filters and lint traps will cause low water flow to the heater and may
cause the water pressure switch to deactivate the heater. If this light stays off, clean all filters and check all
filter system valving to insure proper water flow. See pages 12, 13 and 20, for more information regarding
water flow requirements. When this water flow indicator light is off the t-stat light and the low and high press.
lights will not come on either and the heater will stay off.
T-STAT ON "Green": The green thermostat on indicator light is used to let you know that the thermostat is set
higher than the pool or spa water temperature. If the light is not on, turn the thermostat to a higher position and the
fan should then start, (compressor starts after a 5 minute delay). If the thermostat is already all the way up and the
light is still off, means that the pool or spa water temperature has reached the maximum of 104˚F + or - allowed.
When this light goes off, the heater has heated the pool or spa to the preset temperature. When this light is off the
heater and the low and high pressure lights will stay off.
LOW PRESS. OK "Green": The green low pressure indicator light is designed to let you know that the low side
refrigerant pressure is OK. If the refrigerant pressure was too low for the unit to operate this light the heater will
shut off. The heater is charged with Freon™ (refrigerant). If the outside air temperature drops below 40 degrees
the refrigerant pressure will drop below the required operational range. The internal low refrigerant pressure
switch will act as a defrost control to keep the unit from forming ice on the outer evaporator coil when this light is
off. It may also indicate that the unit may have a refrigerant leak as well. When this light is off the high pressure
light and the heater will be off as well.
HIGH PRESS. OK "Green": The green high pressure OK indicator light is used to tell you that the heater is
operating at the correct high side refrigerant pressure range. If the refrigerant pressure exceeds the maximum
needed for proper operation, this light and the heater will shut off. Excessive high refrigerant pressure is usually
caused by low water flow through the heater. If this light goes out, clean the filtering system and check all
plumbing valves to insure proper water flow then try to restart the heater. See pages 8,18 and 19 for information
CAUTION
(To use indicator lights see
troubleshooting guide pages 26 & 27)
POOL MODE "Yellow": The yellow pool mode in-
dicator light lets you know that you have selected the
pool mode with the pool /spa select switch, (dual thermostat control only). This light will be off when the
control is in spa mode.
START UP PROCEDURES
COMPRESSOR TIME DELAY
BE AWARE THERE IS A 5 TO 7 MINUTE TIME DELAY BEFORE THE COMPRESSOR WILL START
ONCE THE UNIT IS TURNED ON OR WHENEVER
IT RESTARTS. All models.
TURN T-STAT ALL THE WAY DOWN
Make sure the thermostat dial is turned all the way to
the “LEFT” so the unit will not start until you are ready.
Then turn the circuit breaker on.
CLEAN FILTERING SYSTEM
Next, make sure that the pool filter is as clean as possible. A dirty filter will hamper the efficiency of the
unit and cause the unit to cycle on and off resulting in
damaging effects. Filters may look clean but can be
clogged with oils or minerals. Replacement is suggested
every year and a half for cartridge type filters. See manufacturers directions for proper filter cleaning methods.
Next clean the lint trap basket inside the circulation
pump. Then clean the skimmer leaf trap basket of all
debris. A clogged lint trap or skimmer basket will
restrict the water flow to the unit. Make sure there is
adequate water in the pool so that the skimmer does not
draw air. Never place any chemicals of any type, especially chlorine, in the skimmer.
ADVISE YOUR POOL SERVICE CO.
If you have a regular pool service on a weekly basis
make sure your owners manual available for them to
inspect. You may request that one be sent to them, by
calling the factory service department at (941) 768-1555.
Be sure that they are aware of the chemical balance and
chemical introduction rules, in this manual. The conditions in this manual must be followed in accordance with
the warranty, if for any reason, the heater is improperly
installed and or operated, the manufacturers warranty
may be void.
If you are unfamiliar with your pool filtering system,
you should consult your local pool company. The diagram shown above are not of any specific brand but are
common in nature. The following diagram is of a typi-
WATER FLOW & EXISTING WATER PUMP
To filter the pool water each day, the water pump will
come on & off according to the existing timer device.
The heater will only heat if there is water running through
it.
Filter & Trap Locations
WATER PRESSURE SWITCH
If there is proper water flow through the unit
the water pressure switch will close allowing
the unit to run. When the circulation pump
timer stops the water flow, the water pressure
switch will shut the unit down. When the pump
restarts for the next day, the pressure switch
will close and allow the heater to run.

THERMOSTAT CONTROL & SETTINGS
COMPRESSOR
Once the fan is running, the compressor will start 5 to
7 minutes later, it's controlled by a time delay device.
The compressor pumps and compresses refrigerant gas. When refrigerant gas is compressed it intensifies the heat before it is
release to the pool water. This compressed
hot gas is pumped through the heat exchanger where it delivers heat to the pool
water passing through the same heat exchanger.
EVAPORATOR AIR COIL
The fan circulates the warmer outside air through the evaporator air
coil to collect any available heat. The
cooler Freon™ absorbs this heat
causing it to evaporate into a gas.
Therefore the compressor can compress the gas to maximize the gain
heat from the air. The fan discharges
cooler air when the compressor is running. Process is
reversed in Heat & Cool models while in cooling mode.

SYSTEM OVERVIEW
The heat pump system
uses 410-A refrigerant to
transfer the heat from the
outside air to the pool
water.
OPERATIONAL SEQUENCE
THERMOSTAT CONTROL & SETTINGS FOR
HEAT & COOL MODELS
For heating modes on these models,
make sure toggle is selected to heat and
follow the previous instructions above.
For cooling mode make sure toggle is
selected to cool. Turning down the thermostat counter clockwise will start the
unit running. When the pool water has
been cooled to the thermostat setting,
the unit will shut off. When the pool
water temperature rises one to two degrees, the thermostat will activate the unit. There are no temperature graduate numbers printed on the thermostat face. To obtain an
exact temperature, turn the t-stat all the way down and
then place a pool type thermometer in the pool water itself. Once the water has reached your target temperature
on the thermometer, turn the thermostat knob forwards
until the heater just shuts off. Therefore your thermostat
will be set at the thermometer reading.
Heat Cool
Turning up the thermostat will start the
unit running. When the pool water has
been heated to the thermostat setting, the
unit will shut off. When the pool water
temperature loses one to two degrees,
the thermostat will activate the unit.
There are no temperature graduate num-
bers printed on the thermostat face. To
obtain an exact temperature, turn the t-stat
all the way up and then place a pool type
thermometer in the pool water itself. Once
the water has reached your target temperature on the thermometer, turn the thermostat knob backwards until the heater just
shuts off. Make a mental note of knob indicator. Therefore your thermostat will be
set at the thermometer reading.
FAN-AIR CIRCULATION
Once the t-stat is activated the
fan will begin to turn. To absorb heat energy, the fan circulates warmer air through the
evaporator coil at about 4000
cubic feet per minute. The fan
runs independently from the
compressor. The compressor
will start within 5 to 7 minutes
HEAT EXCHANGER
The compressed hot refrigerant releases it's heat to the
pool water inside the heat exchanger. The exchanger is
a tube within a tube construction, water passing through
the inner tube, hot gas passing
through the outer tube. The refrigerant is transformed into a liquid state
as it exits the heat exchanger. There-
fore it is also referred to
as a condenser coil. (Heat & Cool Models,
process is reverse). The exchanger is encased inside a block of closed cell foam to
prevent heat loss and corrosion.
See the cross section.
TIME CLOCK SETTING
Now that all the filters are clean and the pump is running with a full prime, you will need to set the pool
circulation pump timer. Set the filter pump time clock
for a long enough period of time to heat the pool or spa.
The heater will not operate unless there is water running through the heat exchanger supplied by the circulation pump. Therefore, your pool will only heat during the period set on the timer. When setting the timer,
be sure that you shut off the pool circulation pump circuit breaker. Then follow the timer manufacturers instructions to prevent electrical shock. Consult your
dealer first.
INITIAL HEAT UP TIME (HEATERS)
You should start by letting the circulation pump run 24
hours a day until the pool reaches the desired temperature. Once the pool is up to your desired temperature
you should reset the timer for a cycle of 6 to 18 hours
per day during the hottest part of the day. Heat up time
and operational time will vary with pool size, exposure
and weather conditions. Spas will require considerably
less time to reach temperature, usually in a matter of
hours if a cover is used.
INITIAL COOL DOWN TIME
(HEAT & COOL MODELS)
You should start by letting the circulation pump run 24
hours a day until the pool reaches the desired temperature. Once the pool is down to your desired temperature you should reset the timer for a cycle of 6 to 18
hours per day during the coldest part of the day. Cool
down time and operational time will vary with pool size,
exposure and weather conditions.
ADJUSTING THE TIMER
Timer styles vary, read the manufacturers instructions
before attempting to reset timer. Make sure the plastic
guard is in place. On this type of timer, note the On
and OFF trippers located on the clock face. If you
loosen the lock screw on the tripper you can move it to
a new time. Make sure the time of day is correct.
To run the 24 hours needed for the initial heat up, just
remove the "OFF" tripper. When the pool reaches temperature, replace the tripper and set timer to run the water
pump during the hottest part of the day.

COMMON MECHANICAL TIMER
Read your particular timer manufacturers instructions
to identify the one you have. Do not attempt to adjust
the timer unless you have read these instructions.
NORMAL RUNNING TIME
The heat pump system extracts the heat from the outside air and delivers it to your pool. Therefore it produces more BTU's (heat) the warmer it is outside. So
take advantage of the higher air temperatures during
the day by setting the timer for the warmest hours. Winter operation (during cold fronts) may require longer
run times up to 16 hours daily.
SET THERMOSTAT TO MAXIMUM
Turn the thermostat dial all the way to the right. You
will turn the thermostat back to a lower position later,
as described on the next page. The fan should now be
turning.
There is a compressor start time delay and generally it
will not start for about 5 to 7 minutes. Cooler air will
come from the fan when the compressor is running.
Become familiar with the compressor sound and remember the compressor time delay.
Scroll compressors may not start on the first try. Allow
Scroll type compressors several starts and time delay
cycles before the compressor starts. This condition is
most common to new compressors or when starting
THERMOSTAT SETTING
If the pool temperature on the thermometer reads 80 degrees F, and
you turn the thermostat to the "left" until the heater shuts off, the
thermostat will now be set at 80 degrees F.
Thermometer
104˚F
Max.
There are no temperature reading numbers printed on the thermostat dial due to calibration changes from unit to
unit. The demand for exact temperatures should be regulated by using a high quality thermometer right in the pool
water. Normal temperatures for pools are 78 to 82 degrees F. Spa temperatures are 98 to a maximum of 104
degrees F.
You should place a high quality "tie on type" or a "floating type" thermometer directly in the pool or spa water, so you can determine what temperature that is suitable to you. Check the pool temperature occasionally during
the heat up time until it has reached the temperature you desire.
Then go to the heater and turn thermostat counter clockwise, to the left,
away from warmer, SLOWLY until the unit just shuts off. Therefore, the
thermostat will be set exactly at the current temperature shown on your
floating thermometer. Make a mark on the thermostat dial so you know the
approximate setting that you desire.
50˚F
Min.
+ or - 1.5˚F
Now the heater will come on each day when the circulation pump starts, then it will bring the pool up to that set
temperature. The pool will lose some heat overnight but will come back up to temperature with minimal delay. If
you have a pool and spa combination, you can set the spa thermostat the same way once you are in the spa heating
mode. When adjusting the thermostat, remember that it will take some time for the water temperature to reach a
higher setting. The cooler the outside air, the longer heat up time needed.
CAUTION
MAKE SURE YOU ADJUST THE THERMOSTAT BACK FROM THE HIGHEST POSITION SET DURING
THE START UP PROCEDURE OR THE POOL MAY GET TOO WARM. BE SURE TO RESET THE CIRCULATION PUMP TIMER FOR 6 TO 18 HOURS PER DAY OR AS NEEDED, ACCORDING TO THE SIZE OF
YOUR POOL AND WEATHER CONDITIONS. COLDER CLIMATES WILL REQUIRE MORE TIME.
LARGER POOLS WILL REQUIRE MORE TIME. EXPOSED POOLS WILL REQUIRE MORE TIME. WINTER TIME OPERATION WILL REQUIRE MORE OPERATIONAL TIME EACH DAY.
