Introduction
This pool/spa heat pump is an electromechanical machine that incorporates
a pressurized refrigerant gas in a sealed system. ONLY trained and qualified
service personnel are authorized to install or service this equipment.
Without proper training and knowledge of such equipment, any attempt to
install or service the unit could result in serious injury or even death.
This manual contains important information on the use, maintenance and troubleshooting of your
new heat pump. This unit must be properly installed, maintained and operated for optimal
performance. This heat pump is an extremely efficient, economical machine designed
specifically for swimming pool heating. It is similar in design and operation to a typical residential
air conditioning system. The heat pump employs a hermetic motor/compressor operating in a
refrigeration cycle to extract heat from ambient air and deliver it to the circulating pool water.
As with all pool heat pumps, compared to other types of heaters such as gas- or oil-fired, this heat
pump has lower heating capacity on a BTU/hr basis. As a result, it will be required to operate longer
to accomplish the desired results. It may, at certain times, operate as much as 24 hours per day.
However, this should not be of concern to the owner, because the unit is designed to operate
continuously. Even though it may operate continuously for many hours, it will still heat the pool
with greater economy than other types of fossil fuel heaters.
Place a cover or blanket over the pool at night and other non-use periods. This will keep
evaporation, the cause of the greatest heat loss, to a minimum, and will greatly reduce pool
heating costs. During warmer weather, the cover may be required only at night.
I. Installation Considerations
Do not install the unit within 3 ft of fossil fuel burning heaters. Air intake
along the sides of this heat pump could disturb the combustion process
of the unit, and could cause damage or personal injury.
Mount the unit on a level, sturdy base, preferably a concrete slab or blocks. The size of the
base should be at least 3 ft by 3 ft.
Each side of the unit must be located at least 1 ft from walls, pipes, or other obstructions for
unrestricted air intake and service access.
Page 4

The unit’s supporting base must be high enough to keep unit completely
free of standing water at all times.
Situate the pool heat pump carefully to minimize installation costs while providing maximum
efficiency of operation, and to allow adequate service access, as follows:
Air flow path: For unrestricted air intake, position the unit at least 1 ft from walls, pipes and
other obstructions, but allow 2 ft access to the service panel.
The unit is designed for outdoor installation; do NOT install it in an enclosed area such as a
shed or garage, unless ventilation is provided to ensure adequate air exchange for proper
operation. Recirculation of cold discharge air back into the evaporator coil will greatly
reduce the unit’s heating capacity and efficiency.
This unit feature an ‘up-flow’ discharge for quiet operation. Air is pulled up through the
evaporator coil and discharged through the top grill. Allow at least 8 ft clearance above the
unit for unrestricted air discharge. Do NOT install the unit under a porch or deck.
To minimize water piping, locate the unit as close as possible to the existing pool pump and
filter.
When installed in areas where freezing temperatures can be encountered, drain the water
circuit to prevent possible freeze-up damage. See Section IX, Freeze Protection.
II. Electrical Connections
Refer to the unit rating plate below the control panel for precise power requirement for your unit,
and for ampacity and over-current protection requirements.
This unit is pre-wired to work with external control systems, heat-on-demand options and other
external time clock overrides. Refer to the external control system’s instructions for installation
information.
III.Water Connections
The heat pump inlet and outlet connections are NOT interchangeable.
They must be connected as instructed below.
1. Connect the heat pump in the return water line between the filter and the pool/spa. See Plumbing
Diagrams.
2. Connect the filter outlet to the fitting marked WATER IN at the bottom front of the unit.
3.Connect the fitting marked WATER OUT to the return piping to the pool/spa. Unit inlet/outlet
connection fittings are PVC unions. Water connections from the heat pump to the main return
line can be PVC pipe or flexible pipe approved for the purpose and, in either case, should be at
least equal in size to the main pool/spa circulation piping.
4. In cold weather (freeze zone) areas, shutoff valves (ball or gate type) must be installed at the
heat pump inlet and outlet to facilitate service and cold weather drain-down.
5. Operate the pump and check the system for leaks.

Install a check valve and/or Hartford loop a minimum of 18 inches higher
than the top of the chlorinator BETWEEN the heat pump and any automatic
chlorinating devices. Follow the chlorinator manufacturer's instructions.
Improper installation of erosion-type automatic chemical feeders can result
in serious damage to the heat pump.
IV. Control Panel
Your heat pump incorporates controls and indicators to ensure its safe, reliable operation.
Water Temperature Control: Pool water temperature is controlled by the heat pump thermostat
on the unit control panel, which contains a switch and 2 thermostats, one for setting a heat
temperature and the other for setting cooling temperature. The switch can operate an optional
external control system, or can switch between heat and cool.
NOTE: The heat pump will not run when the Remote position is selected
and there is no remote control system attached.

INDICATOR LAMPS
There are 3 indicator lamps located on the unit control panel:
Power (red lamp): When lit, indicates power is applied to the unit.
NOTE: The heat pump will not run when the Remote position is selected
and there is no remote control system attached.
Heat Light
(Green lamp): When lit, indicates that the unit is in the heating mode
Cool Light (Green lamp): When lit, indicates that the unit is in the cooling mode.

V. Initial Start-Up and Check
1 . Verify that the Power lamp is ON and that the pool/spa pump is running and circulating
properly.
2. Verify that the control panel Heat-Remote-Cool switch is in the Remote (OFF) position; see
the figure.
3.Turn the control switch to Heat and to turn the pool system ON. Raise the thermostat setting
above the current water temperature. The fan and compressor should start up and run
simultaneously.
NOTE: The heat pump will be OFF when the Remote position is selected on the Heat-Remote-Cool
selector switch and there is no remote control system attached.
4.Allow the heat pump to operate for a few minutes to stabilize operating pressures and to
allow various component temperatures to normalize.
5.Verify that the discharge air temperature is approximately 8° - 10° cooler than the air entering
the unit when heating.
A. Heating Mode
Whether heating or cooling, the unit is designed to operate up to 24 hours a day.
1. Set the Heat/Cool switch on the control panel to Heat mode
2. Rotate the thermostat control knob to the desired water temperature. Whenever the setting on
the thermostat control knob is above the actual water temperature, the fan will run.
NOTE: Whenever the unit is turned OFF, and turned back ON the fan will start but the compressor will not
restart for approximately 5 minutes. This delay protects the compressor.
Heating Confirmation - After a few minutes of operation,the unit will begin heating. Again,
discharge air temperature should be 8° - 10° cooler than the air entering the unit when heating.
Initial Heating - Check the water temperature and note the time. A heat pumps warms slower but
more economically than other heaters. The rate of heating depends on 3 factors:
How many pounds of water to be heated (10,000 gallons = 83,300 pounds of water).
How many degrees the water needs to be heated. It takes 1 BTU to heat 1 pound of water 1°.
How many BTUs the water loses. The warmer the air, the less time it takes to heat the water.
NOTE: Use a pool blanket to reduce BTU loss. Also turn off all fountains, sprays
and other water features.
Initial heating time (operating 24 hours per day) may vary from 2 days to 1 week. After initial
heating, operating time is reduced to match heat loss.

Daily Heating Cycle
Most heat pumps are sized to operate during the pool filtering cycle time of 8 - 10 hours daily to
provide an even, steady flow of warm water over a long period of time. On warmer days, the unit
will run less, on cooler days, longer. To accomplish this, set the time clock for longer run times.
Hint: Remember, heating is more efficient during the warmer daylight hours.
Every pool/spa environment is unique in terms of location, use, swimming hours, solar exposure,
shade, wind, etc. Therefore, heat pump operating time will differ between pools/spas.
B. Cooling Mode
Utilizing proven heat pump technology, your unit takes heat from the pool/spa water and transfers
it to the air the same way your home air conditioner does. In cooling mode, running the unit
during the night, when air temperature is the lowest, will give you the highest efficiency.
1. Set the Heat- Remote-Cool switch on the control panel to Cool mode.
2. Rotate the thermostat control knob to the desired water temperature. Whenever the setting on
the thermostat control knob is below the actual water temperature, the unit’s fan and
compressor should be running.
NOTE: Whenever the unit is turned OFF, the compressor will not restart for 6
minutes. This delay protects the compressor.
Cooling Confirmation - After a few minutes of operation the unit will begin cooling. The
discharge air temperature should be warmer than the air entering the unit.
Initial Cooling - Check the water temperature and note the time. The rate of cooling depends on 3
factors:
How many pounds of water to be cooled (10,000 gallons = 83,300 pounds of water).
How many degrees the water needs to be cooled. It takes 1 BTU to cool 1 pound of water 1°.
How many BTUs the unit transfers to the water. The cooler the air, the less time it takes to
cool the water.
NOTE: Remove the pool/spa blanket to speed cooling. Also, turn ON fountains,
sprays and other water features as that will assist in cooling the pool.
Initial cooling time (operating 24 hours per day) may vary from 2 days to 1 week. After initial
cooling, operating time is reduced to match heat gain.
Daily Cooling Cycle
Most heat pumps are sized to operate during the pool filtering cycle time of 8 - 10 hours daily to
provide an even, steady flow of cool water over a long period of time. On warmer days, the unit
will run longer, on cooler days, less. To accomplish this, set the time clock for longer run times.
Hint: Remember, cooling is more efficient during the cooler nighttime hours.

VI. Seasonal Start-Up or Annual Check
NOTE: At the beginning of the heating season or whenever the pool water temperature
is to be raised several degrees, the pool pump and heat pump may need to operate
continuously for several days. During summer months, only a few hours per day
may be necessary or none at all.
1. Remove leaves, pine needles, etc. from the evaporator coil. Clean the coil by gently applying
a mild solution of household liquid soap and water.
2. Gently rinse the coil with water; do NOT use high pressure.
3. Backwash or otherwise clean the pool filter. If necessary, clean the skimmer basket and pump
strainer.
4. Set the valves to assure proper water flow through the unit.
NOTE: If the pool pump and heat pump shut OFF before the water temperature is
raised to the desired level, you must lengthen the running time of both. To do this,
reset the time clock dial for the longer running time, or manually operate the pump
with the timer override switch. Since the heat pump capacity and efficiency are both
greater at higher ambient air temperatures, run time should be set to take
advantage of all daylight hours, when the air is generally warmer.
VII. Heat Pump Running Time
1.Determine the length of pump and heat pump operating time necessary for your particular
requirements. Minimum run time should be the required hours to attain proper water filtration.
Maximum run time obviously is 24 hours per day, or as required to reach desired water
temperature, and depends on such things as weather, pool/spa size, covering, shading, etc.
2. If cooler or warmer water is desired, simply adjust the water temperature control and/or the
pump and heat pump operating time until the desired water temperature is reached.
NOTE: At the beginning of the heating season, or whenever the pool/spa water
temperature is to be raised several degrees, the pool pump and heat pump may
need to operate continuously for several days. During summer months, only a few
hours per day may be necessary, or none at all.
VIII. Summer Shutdown
If you do not plan to use the heat pump during the summer months, secure and protect it
as follows:
1. From the control panel, turn the control switch to Remote (OFF).
2. Turn the heat pump circuit breaker or disconnect switch to OFF.
3. Leave the valves set the way they are unless additional circulation is required. DO NOT stop
all flow through the heat pump.
4. IMPORTANT: Remember to reset the valves before the next heating season, or the heat pump
will not operate properly.
