Congratulations and Thank You for purchasing the most advanced high
efficiency, microprocessor-controlled pool and spa heat pump available!
Your heater has been manufactured with the most state-of-the-art quality control
equipment available today to ensure the highest quality product delivered to your door.
A heat pump pool heater is a highly efficient, cost effective method of pool heating.
Proper operation and care will result in many years of swimming enjoyment and
pleasure.
Your new pool heater is a self-contained unit designed specifically for swimming pool
and spa heating. It utilizes the sun’s free energy by extracting heat from the sunwarmed air and transferring it efficiently to the pool water. Because your pool heater
moves the free heat from the outside air to the pool, rather than create heat, as a fossil
fuel or electric resistance heater does, it can heat your swimming pool or spa for up to
80% less cost than these other less efficient methods.
As with all pool heating methods, you are advised to utilize a pool cover at night and
when the pool is not in use. The pool cover should be used if the Night temperature is
15˚F (8˚C) less than the desired pool temperature. This will keep evaporation, the
greatest source of heat loss, to a minimum, greatly reducing the overall pool heating
costs. During warmer weather, the pool cover may not be required.
Your pool and spa heater combines simplicity with trouble-free performance. As with
most appliances, an understanding of proper operation of the heater is important.
Proper installation and operation increases efficiency and reduces heating costs. Your
pool heater is designed with features that make it simple to operate, maintain and
service. This manual will provide you with the information needed to properly operate
and maintain your heater.
ATTENTION:
Please be sure to complete and mail in the
Warranty Registration Card, enclosed with your heater.

WATER CHEMISTRY MAINTENANCE
Not only is the water chemistry of your pool or spa important to the health of
you and your family, it also directly affects the life of your heater. This is the
most important item in the maintenance of the heater. If the water chemistry is
improperly maintained or if the chemicals are improperly introduced into the
water, this will damage the heater’s internal components and could eventually
cause a leak, rendering the heater inoperable.
WARNING:
Damage to the heater due to improper water chemistry
is not covered under the warranty.
Following is the table for essential water quality readings, which must be
constantly maintained:
Description
Normal Range
Verify
PH Level
7.4 to 7.8
1 time per week
Chlorine Concentration
1.0 to 3 PPM
1 time every 2 to 3 days
Total Alkalinity
80 to 120 PPM
1 time every 2 to 3 weeks
Total Dissolved Solids
Below 2400 PPM
1 time per month
Calcium Hardness
200 to 300 PPM
1 time per month
The location of the chemicals’ introduction to your system is also critical to the
heater’s life. If an automatic in-line Chlorinator or Brominator is used, it must be
located downstream of the heater. A Trap/ Check Valve must also be installed
between the chlorinator and the heater to prevent chlorine return into the
heater.
WARNING:
Never leave any type of solid chlorine in the pool skimmer. This will
cause a high concentration of Chlorine to enter the heater, causing
premature corrosion. Never add chemicals into skimmer, this will cause
warranty to be voided

HEAT PUMP FEATURES
CABINET – Your heat pump’s cabinet is made from a maintenance-free, rustfree plastic that is UV resistant. It will last for years and any dirt or dust may
simply be wiped away with a cloth or sprayed off with a water hose. Use only
cleaner designed for plastic.
CAUTION:
Do Not Use Cleaners That Contain Alcohol.
CONTROL - State-of-the-art LCD readout control.
Displays mode and
temperature of the water for ease of operation. No programming to learn. Dual
thermostats allow user to set pool and spa temperatures. The control is selfdiagnostic and will display a fault if there is a problem. Other features include:
lockout, spa timer, automatic low temperature defrost, remote control
capabilities, even-heat, and solar control.
ULTRA-QUIET - The unit is equipped with a low RPM fan motor in
combination with a deep drawn venturi to ensure whisper quiet operation.
HIGH EFFICIENCY – The heat pump utilizes the latest in compressor
technology to produce the highest efficiency available when coupled with the
over-sized enhanced fin evaporator coil, and rifled titanium tube heat exchanger.
EASE OF INSTALLATION - The unit is equipped with easy-to-install, handtightened unions for a quick and trouble-free installation. The unions will accept
2” PVC piping. The electrical connection is made with one entry directly into the
control box for a quick hook-up and a neat appearance.
EASY ACCESS – The heater was designed for quick and easy access for
installation and diagnosis. The service panel is removed with two screws and
access to all service connections is right up front and easy to reach. This allows
the installation and service to be done quickly and efficiently – so valuable time
is not wasted.
EVEN-HEAT - (Additional wiring required) This feature allows the heater
to periodically turn pool circulation pump on and test water temp, if temp is
below the set point programmed on board, the heater will run pool pump until it
reaches set point, then it will shut unit and circulation pump back off. Feature
can be set to run in one-hour increments
SOLAR CONTROL - (Additional wiring required) The board can be set to
run and monitor your pool solar systems. There is no need to have a second and
separate control system.

HEAT PUMP OPERATION
CONTROL ON/OFF
When the unit is powered up, but in the OFF mode, temperature will not be
displayed. To turn the unit on, press the UP arrow button until desired
temperature is reached. To turn the unit off press and hold the DOWN arrow
button until the display shows off. This point will be one level below 50 degrees.
This is convenient for shutting the unit down for short periods of time.
CAUTION:
When the control is in the “OFF” mode, there is still high voltage to the
unit. If you want to turn the unit off for long periods of time, shut the
main power off to the unit at the main or service disconnect.
POOL/SPA MODES
The control is equipped with two independent thermostats, one for pool
temperature and one for spa temperature. This is to allow user to preset a
temperature of their choice and switch between the two settings with the
POOL/SPA button located on the control. When power is applied to the control it
will turn on in the previous mode, whether it is Pool Heat or Spa Heat. When
water is flowing through the unit and the water temperature meets the specified
set point condition, the control will initiate a heat cycle.
If you do not have a spa, you can use the spa thermostat as a second
temperature setting if you do not want to maintain full temperature all the time.
For instance, if you swim on the weekends only, you can set the temperature
back during the week to save costs but maintain a warmer temperature for a
shorter recovery time for the weekend.
ATTENTION:
There is a 5-minute time delay upon initiation of a heating cycle. This
is to ensure that the critical components do not fail due to short cycling
of the heater.
The display on the control will show the thermostat being used and the operating
mode on the top line and the current water temperature on the bottom line. The
possible mode displays are: “POOL – HEAT”, “SPA – HEAT”.
Page 7
CHANGING SET POINT TEMPERATURE
To change the set point temperature, press either the UP or DOWN arrow
buttons on the control. The display will then show “POOL TEMPERATURE” on
the top line and the current set point temperature in numbers on the bottom
line. After adjusting to the desired temperature setting, the display will revert to
“POOL – HEAT” (or whichever mode you are in) on the top line and the pool
temperature in numbers with “DEGREES” on the bottom line after 5 seconds of
inactivity and the new set point will be stored in memory. The default factory
setting for Pool Temperature is 85 ˚ Fahrenheit.
HEATER RUNNING TIME
The owner is responsible for determining the necessary length of operating time
for the pump and heater based upon user’s particular requirements. Most units
are sized to operate during the pool filtering cycle time of 8 to 12 hours daily,
providing an even, steady flow of heat. On warmer days the heater will run less
because there will be less heat loss from your pool. The heater is capable of
running 24 hours per day if necessary. Upon initial heating, it may need to run
continuously for 24 to 48 hours to get the pool up to the desired temperature.
KEYPAD LOCKOUT
While in any mode the user can lockout the keypad by pressing and holding the
POOL/SPA button for 6 seconds. When the keypad lockout has been enabled all
buttons are disabled and the control will operate in whatever mode it was in
when the lockout occurred. Any button push while in lockout will
cause the display to show LOCKOUT for 5 seconds. To unlock the Keypad, press
and hold the POOL/SPA button for 6 seconds. The display will show UNLOCKED
for 5 seconds.
DEFROST CYCLE
The heater is designed to enter the defrost cycle at ambient air temperatures
below 48˚ Fahrenheit. During this cycle, the unit may shut down and the
control will display “Defrosting” until the ambient air temperature rises above
frosting conditions.
CONDENSATE DRAINAGE
It is normal for water to be draining from your heater. This occurs because the
evaporator coil condenses the water from the air. The water drains into the base
of the unit and out the holes that are located on each side of the heater at the
bottom. Your heater can produce 1 to 3 gallons of water per hour. The water
created from the condensation will dry up when the heater shuts off.
Page 8
CARE & MAINTENANCE
CLEANING
There is not much maintenance that needs to be done on your heater. Making
sure there is good airflow through the evaporator and proper drainage are the
two main tasks. A garden hose with low-pressure water flow can be used to
clean the evaporator coil. Keep all shrubs trimmed back away from the unit to
allow sufficient airflow.
CAUTION:
Make sure all power is disconnected to the heater prior to washing.
Clean the coil as needed. If located near the ocean, cleaning will need to be
done regularly to remove salt and sand. Use a very soft brush so as not to bend
the coil fins with and use soapy water to remove any build up.
Keep the drain holes in the base free of debris to assure proper
condensation drainage.
Your heat pump’s cabinet is made from a maintenance-free, rust-free plastic that
is UV-resistant. It will last for years and any dirt or dust may simply be wiped
away with a cloth or sprayed off with a water hose. Only use products designed
for cleaning plastics.
WARNING:
DO NOT USE CLEANERS THAT CONTAIN ALCOHOL
Alcohol based cleaners may damage the plastic.
WINTERIZING
In areas where freezing condition is not prevalent and winterizing of pools is not
common, allow water to flow through the heater even when not in use.
ATTENTION:
In freezing areas, it is mandatory that the water be completely drained
from the heater and disconnected from the piping. The heat exchanger
must be blown out with air to ensure no water in the heat exchanger.
Page 9
TROUBLESHOOTING
A simple test to verify that your heater is functioning is to place your hand above
the unit. There should be cool air blowing out the top after time delay has
expired. The return water to the pool should be a few degrees warmer than
water entering the heater. After about 15 minutes of run time, there should be
water draining out of the base of the unit. If you have reason to believe your
heater is not functioning properly, follow the troubleshooting guide below or call
our Heat Pump Services Department for attention or service.
