Congratulations on purchasing the most advanced high efficiency,
microprocessor-controlled pool , spa and Aquaculture heat pump available. Your heat pump 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 water heater is a highly efficient, cost effective
method of water heating. Proper operation and care will result in many years
of worry free heating or cooling depending on the model you chose .
Your new heat pump is a self-contained unit designed specifically for
swimming pool and spa heating and can be used for
aquaculture applications
when installed properly. It utilizes the sun's free energy by
extracting heat from the sun-warmed air and transferring it efficiently to the
pool/tank water. Because your heat pump moves the free heat from the
outside air to the pool/tank, rather than create heat, as a fossil fuel or electric
resistance heater does, it can heat your pool/spa/tank for up to
80% less cost than these other less efficient methods.
As with all water heating methods, you are advised to utilize a cover at
night. The cover should be used if the night
temperature is 15°F (8°C)
less than the desired water temperature.
This will keep evaporation, the greatest source of heat loss, to a minimum,
greatly reducing the overall heating costs. During warmer weather,
the cover may not be required.
Your pool/spa/tank heat pump combines simplicity with trouble-free
performance. As with most appliances, an understanding of proper
operation of the heat pump is important. Proper installation and operation
increases efficiency and reduces operating costs. Your heat pump is
designed with features that make it simple to operate, maintain and service.
Proper installation enhances these features and minimizes problems. This
manual will provide you with the information needed to properly install,
operate and maintain your heat pump.

Please be sure to complete and mail in the Warranty Registration Card that
is provided in the package with your heater. This card helps us to notify
you about new information on your heater.
Also, please take a moment and jot down the following information. If you
should ever need to call us for service or a question, we will need this
information:
Model Number:___________
Serial Number:___________
Purchase Date:___________
Dealer Name/Address/Phone #:________

The unit is designed for outdoor installation and shall not be placed in a
totally enclosed area such as a shed or a 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 heating capacity and efficiency of the unit and void the compressor
warranty.
The heat pump should be located as close as practical to the existing pool/tank pump
and filter to minimize water piping length. The use of 90° bends and short
radius elbows in the water piping should be limited to keep water pressure
drop to a minimum.
Your heat pump features an up-flow fan for quiet operation. Air is pulled
through the evaporator coil and discharged through the top grill. At least 4
feet clearance should be allowed above the unit for unrestricted air
discharge. The unit must not be installed under a porch. Any side of the
unit should be located at least 12 inches from a wall or other obstruction for
unrestricted air intake and service access.
Mount the unit on a flat, level surface, preferably a concrete or fabricated
slab. The unit should be completely isolated from the building foundation or
wall to prevent the possibility of sound or vibration transmission into the
building. The base of the unit may be used to fasten to if local codes
require securing the unit to the slab.
Make sure that there are no sprinkler heads near or directly spraying into
the heater. Cap off or redirect heads as needed.
The unit can be strapped down using a strap kit. Attach a
strap to each side and anchor to the deck.

The piping sequence: pool/tank pump / filter / heat pump / chlorinator (if pool) / pool/tank.
Note for Pools:
In-line chlorinators must be down stream of the heater to minimize harm to the
pool equipment.
Rigid PVC piping is recommended and all joints should be
secured with PVC glue. Make sure that the direction of the water flow
through the heat pump is correct as indicated by the labels on the unit. When
the piping installation is complete, operate the pool pump and check the
system for leaks. Check the filter pressure gauge to ensure that excessive
pump head pressure is not indicated.
The recommended flow rate is 50 gpm through the heat pump.
For questions on multiple unit installations, please contact our
main office. Multiple unit installations should always be in
parallel circuits.
CAUTION: The main power disconnect must be off before opening the
access panel.
It is required that the wiring of your heat pump be done by a qualified
electrician in accordance with local code requirements.
IMPORTANT: The electrical conduit must be run up through the base of
the unit and connected at the control box with a conduit connector.
A properly sized breaker and copper wire must be used. See inside access
panel for wiring diagram.
Page 7
Because all metals have different electrical potentials, ALL metal
and electrical components of the pool/tank system must be bonded
together. This includes the metal framework of the pool/tank, lights, pump,
filter, heater, any automatic chlorine generator and any other metal or
electrical equipment. On some older pools, this substructure bond wire may
not exist. In this case, a 6 to 8 ft. copper rod must be driven into the
ground near the pool/tank equipment and all electrical and metal components
must be bonded to the rod. A bonding lug is furnished on the side of the
control box of the heat pump for the bond wire to be attached. Warranty will
be void if system is not properly bonded.

Not only is the water chemistry of your pool, spa or tank important to human health
or livestock health, it also directly affects the life of your heat pump. This is
the most important item in the maintenance of the heat pump. If the water
chemistry is improperly maintained or if the chemicals are improperly
introduced into the water, this will damage the heat pump's internal heat
exchanger and could eventually cause a leak, rendering the heat pump
inoperable.
CAUTION: Damage to the heat pump 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 for swimming pools and spas:
|
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 heat pump's life. If an automatic in-line chlorinator or brominator is used, it
must be located downstream of the heat pump. A trap must also be installed
between the chlorinator and the heat pump to prevent chlorine return into the
heat pump.
Note for Swimming Pools and Spas:
IMPORTANT: Never leave any type of solid chlorine in the pool skimmer.
This will cause a high concentration of Chlorine to enter the heat pump, causing
premature corrosion. You must divert water flow directly to the pool/tank before
adding fast dissolving chemicals in skimmer.
* Models with Titanium Tube heat exchangers do not have a water
chemistry exclusion in their warranty.

CABINET – 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. The use of a product such as Armor- All will restore its natural luster.
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, spa or tank temperatures. The control
is self-diagnostic and will display a fault if there is a problem. Other
features include: lockout, spa timer, automatic low temperature defrost and
remote control capabilities.
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.
EASE OF INSTALLATION - The unit is equipped with easy-to-install,
hand-tightened 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 heat pump 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.

When the unit is powered up, but in the OFF mode, the display will show
"OFF". 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.
The control is equipped with two independent thermostats, one for pool
temperature and one for spa temperature in case
of swimming pool application.
This is to allow the 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 completion of a
heating/cooling cycle. This is to ensure that the critical components do
not fail due to short cycling of the heat pump.
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 11
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 degrees Fahrenheit.
The owner is responsible for determining the necessary length of operating
time for the pump and heat pump based upon their particular requirements.
Most units are sized to operate during the pool/tank filtering cycle time of 8 to 12
hours daily, providing an even, steady flow of heat. On warmer days the
heat pump will run less because there will be less heat loss from your pool/tank. The
heat pump is capable of running 24 hours per day if necessary. When you first
run your heat pump, it may need to run continuously for 24 to 48 hours to get
the pool/tank up to the desired temperature.
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.
The heat pump 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.
It is normal for water to be draining from your heat pump. 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 heat pump can produce 1 to 3 gallons of water per
hour. The water created from the condensation will dry up when the heat pump
shuts off.
Page 12
There is not much maintenance that needs to be done on your heat pump.
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. Make sure the heat pump has good ventilation to allow sufficient airflow.
CAUTION: Make sure all power is disconnected to the heat pump 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 soapy water to remove any build up. Keep the
drain holes in the base free of debris to assure proper condensate
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. The use of a
product such as Armor- All will restore its natural luster.
DO NOT USE CLEANERS THAT CONTAIN ALCOHOL.
Alcohol based cleaners may damage the plastic.
In areas where freezing condition is not prevalent and winterizing of pools is
not common, allow water to flow through the heat pump even when not in use.
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 13
A simple test to verify that your heat pump 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/tank 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 the factory for service.
