1.2 Working principles
High efficiency
With a COP value up to 5.0 our heat pumps are very efficient when transferring heat from the air to
the swimming pool water. You can save as much as 80% of cost compared to an electrical heater.
Long life-span
The heat exchanger is made of PVC & Titanium tube, which can withstand and prolong exposure to
swimming pool water.
Easy control and operation
The unit is very easy to operate: simply switch it on and set the desired pool water temperature.
The system includes a micro-computer controller, allowing all operation parameters to be set.
Operation status can be displayed on the controller with LCD display.
Heat pumps utilize the sun's free heat by collecting and absorbing energy from the outside air. This
energy is then compressed and transferred to the pool water. Your existing water pump circulates the
water through the heater, usually next to the pool equipment, and the water warms up. The heat pump
timer could be set to operate during daylight hours, for example, usually 9am to 5pm.
The unit contains a fan that draws in outside air and directs it over the surface of the EVAPORATOR
(energy collector).The liquid refrigerant within the EVAPORATOR coil absorbs the heat from the
outside air becomes a gas.
The warm gas in the coil passes through the COMPRESSOR concentrating and increasing the heat to
form a very hot gas which then passes to the CONDENSER (water heat exchanger).It is here that the
heat exchange occurs as the hot gas gives off heat to the cool swimming pool water circulating through
the coil.
The pool water becomes warmer, and the hot gas cooling as it flows through the CONDENSER coil-
returns to its liquid form and, after passing on through the CAPILLARY TUBE, the whole process
begins again.
The state of the heat pump technology can efficiently collect heat from the outside air down to the 7℃ to
10 range. For tropic and subtropical climates, this means that the pool can be maintained at 26℃ to 32℃

1.3 Location of heat pump installation
The unit will perform well on any location provided three factors are present:
1. Fresh air - 2. Electricity - 3. Pool filter piping
The unit may be installed virtually anywhere outdoors providing minimum distance requirements are met
with respect to other objects (see diagram below).For indoor pools please consult your installer. If the unit
is placed in a windy area, no problems occur with e.g. the pilot light, as opposed to what is often the case
with gas heaters.
Attention: Do not place the unit in an enclosed area with a limited air volume where the unit's discharged
air will be re-circulatedor near shrubs that could block the air inlet. These locations deny the unit a
continuous fresh air supply, which reduces its efficiency and may prevent adequate heat yield.
See diagram below for minimum required distances.
Cautions
- Do not put your hands or any other object into the air outlet and fan. It could damage the heat pump and
cause injuries.
- In case any abnormality was found in the heat pump, please cut off the power at once and contact a
professional technician.
- It is strongly suggested to place a guard around the machine to keep children away from the heat pump.

1.4 Distance from the pool
Normally, the pool heat pump is installed within a 7.5 meter radius of the pool. The greater the distance
from the pool, the greater the heat loss from the piping. Since the piping is buried for the most part,
heat loss is minimal for distances of up to 30 meters (15 meters to and from the pump= 30 meters total),
unless the soil is wet or the water level is high. Heat loss per 30 meters could roughly be estimated at 0.6
kw-hour (2000 BTU) for every 9 temperature difference between the pool water and the soil
surrounding the pipe, which translates to an operation time increase of 3-5％.
1.5 Installation of the check-valve
Attention- When using automatic chlorine and PH dosage systems, it is of uttermost importance to protect
the heat pump from high concentrations of these chemicals that could corrode the heat exchanger.
Therefore, such systems should add the chemicals in the conduits located DOWNSTREAM of the heat
pump and it is recommended to install a check-valve in order to prevent backflow when there is no water
circulation.
Damage to the heat pump caused by disregarding any of these recommendations will invalidate the warranty.

Important—Although the heat pump is electrically isolated from the rest of the unit, this only prevents
the passage of electricity to or from the pool water. Grounding the unit is still required to protect
yourself from short circuits inside the unit. Make for adequate ground connection.
Check if the electrical mains voltage corresponds with the operating voltage of the heat pump prior to
hooking up the unit.
It is recommended to use a separate fuse(slow type-D-curve)as well as adequate wiring(see table below).
For horizontal models : remove the panel on the right of the fan opening.
For vertical models: remove the curve panel in the front side.
Connect the electrical wires with the terminal block labelled “Power Supply” .
Next to this connection, there is a second terminal block labelled “ Water Pump”,to which the filter
pump (max.5A/240V)can be connected. This is connection makes it possible to control filter pump
operation with the heat pump. See further at Parameter setting table (Parameter 9) for the different
possibilities.
Remarks—for models with 3 phases, switching 2 phases may cause in inversion in the rotational direction
of electrical motors, which could damage the unit. Therefore, a protection device has been built in, which
will interrupt the circuit if the connection has not been performed correctly.

1.9 First time start-up
Time delay— the unit is equipped with a built-in 3-minute start delay included to protect electrical
components and contacts. After this tim e d ela y, the un it wil l a utomaticall y b e r est arted. Even a
brief interruption of the power supply will activate the start delay and prevent the unit from starting
immediately. Additional interruptions of the power supply during the delay period will have no effect
on the 3-minute countdown.
Water flow switch—the unit is equipped with a flow switch that is switched on when enough water has
flowed through the unit and that is switched off when the water flow becomes too low. (E.g. When the
filter pump is switched off).
When the swimming pool water is being heated by the heat pump, the incoming air is cooled down quite
a bit, which can cause condensation on the fins of the evaporator. Condensed volumes can attain several
litres per hour under high atmospheric humidity. Sometimes, this is wrongfully interpreted as a water leak.
Depending on the starting temperature of the pool water and the air temperature, it can take several days
for the water to reach the desired temperature. Covering the pool can drastically reduced this period.
When all connections have been made and checked, you should follow these steps:
1. Turn on the filter pump. Check for leaks and verify flow to and from the pool.
2. Turn on the electrical power supply to the unit, then press the ON/ OFF key on the electronic control
panel. The unit should start when the time delay period has lapsed .
3. When the unit has been running for a couple of minutes, check if the air leaving the unit is cooler.
4. Check the performance of the flow switch as follows: with the unit running, turn the filter pump off.
The unit should also switch off automatically. If not, the flow switch must be readjusted.
5. All the unit and filter pump to run 24 hours a day until the desired pool water temperature is reached.
When the set temperature is reached, the unit switches itself off. The unit will now automatically restart
(as long as your filter pump is running) when the temperature of the pool water experiences a drop of
more than 34 below the set temperature.
Note- In order for the unit to heat the pool (or spa), the filter pump must be running so that the water
can circulate through the heat pump. Without this circulation, the heat pump will not start.

4. Protection systems
4.1 Water flow switch
Equipped with flow switch the heat pump will not work when the filter pump is not working (and the
water is not circulating).
This system prevents the heat pump from heating only the water present in the heat pump itself.
The protection also stops the heat pump if water circulation is cut off or stopped.
4.2 Refrigerant gas high and low pressure protection
The high pressure protection makes sure the heat pump is not damaged in case of over pressurisation of
the gas. The low pressure protection emits a signal when refrigerant is escaping from the conduits and the
unit can not be kept running.
4.3 Automatic defrost control
When the air is very humid and cold, ice can form on the evaporator. In that event, a thin layer of ice
appears that will grow increasingly bigger as long as the heat pump is running. When the temperature of
the evaporator has become too low, automatic defrost control will be activated, which will reverse the
heat pump cycle so that hot refrigerant gas is sent through the evaporator during a brief period of time to
defrost it.
4.4 Temperature difference between inflowing and outflowing water
During normal operation of the heat pump, the temperature difference between inflowing and outflowing
water will approximate 18 to 36 .In the event that the pressure switch does not work and that the water
stops circulating, the temperature probe monitoring the outflowing water will always detect a rise in
temperature. As soon as the temperature difference between inflowing and outflowing water exceeds 23.4
the heat pump will be automatically turned off.
4.5 Low temperature cut-out
If, during cooling, the temperature of the outflowing water reaches 41 or drops below this temperature,
the heat pump will turn itself off until the water temperature reaches or exceeds 45 again.
4.6 Anti-frost protection during winter
This protection can only be activated if the heat pump is in STAND-BY status.
16
4.7 First anti-frost protection
If the filter pump is controlled by the heat pump (regardless of the value for parameter 9) and when the
water temperature lies between 36 and 39 ,and the air temperature is lower than .32 ,the filter pump will
be automatically turned on to prevent the water from freezing in the piping. This protection is deactivated
when the temperature rises again.
4.8 Second anti-frost protection
If the water temperature drops even more, that is, below 36 (during long frost periods), the heat pump
will also start running to heat the water until its temperature approximates 39 . When this temperature
is reached, the heat pump will stop, but anti-frost protection will remain active until conditions change.
17
5. Direction
5.1 Swimming pool water chemistry
pH
Free chlorine(mg/1)
TAC(mg/1)
Salt(g/1)
Important: failure to comply with these limits will invalidate the warranty.
Note: exceeding one or several limits can damage the heat pump beyond repair. Always install water
treatment equipment past the heat pump's water outlet, especially if the chemicals are automatically
added to the water.
A check-valve should also be installed between the outlet of the heat pump and this equipment in
order to prevent products from flowing back into the heat pump if the filter pump stops.
Special attention should be paid to the chemical balance of the pool water. The pool water values should
always stay within the following limits:
Min
7.0
0.5
80
Max
7.4
1.2

5.2 Heat pump winterizing
Important: failure to take the necessary precautions for winterizing can damage the heat pump,
which will invalidate the warranty.
The heat pump, filter pump, filter and conduits must be protected in areas where the temperature can drop
below the freezing point, Evacuate all water from the heat pump as follows:
1. Interrupt the electrical power supply to the heat pump
2. Close the water supply to the heat pump: completely close valves 2 and 3 of the by-pass
3. Disconnect the water inlet and outlet coupler fittings of the heat pump and let the water drain out of the
unit
5.3 Restarting the pump after winter
If you purged your heat pump for winterizing, you should undertake the following steps to restart it in spring:
1. Check first if there is no dirt in the conduits and if there are no structural problems
2. Check if the water inlet and outlet coupler fittings are adequately fastened to the heat pump
3. Start the filter pump to start the water flow to the heat pump. Set the by-pass again.
4. Reconnect the electrical power supply to the heat pump and turn it ON.
4. Loosely reattach water inlet and outlet coupler fittings to the heat pump in order to prevent dirt
from setting into the conduits.
Note: these precautions should not be taken if you choose to use the built-in anti-frost protection.
18
Condensation can occur when the heat pump is running. This condensation can flow away through an opening
in the base pan of the unit. The amount of condensation water will increase when atmospheric humidity is
high. Remove any dirt that could possibly hamper the evacuation of condensation.
10 to 20 litres of condensation water can be produced while the unit is running. If more condensation is
produced, stop the heat pump and wait for one hour before checking for leaks in the conduits.
Note: a quick way to verify that the water running through the condensation drain is indeed
condensation, is to shut off the unit and keep the pool pump running. If the water stops running out
of the condensation drain, it is condensation. AN EVEN QUICKER WAY is to TEST THE DRAIN
WATER FOR CHLORINE. If no chlorine is detected, the drain water is a result of condensation.
Also take care to leave air inlet and exhaust passages free. Prevent exhaust air from immediately re-entering
the unit through the inlet.
5.4 Check-up
Our heat pumps have been developed and built to last, that is, if they have been installed correctly and can
run under normal conditions. Regular check-ups are important if you want your heat pump to function
safely and efficiently for years on end.
1. Make for easy access to the service panel.
2. Keep the area surrounding the heat pump free of contingent organic waste.
3. Prune the vegetation near the heat pump so that there is enough free space around the pump.
4. Remove contingent water sprinklers from the vicinity of the heat pump. They can damage the heat pump.
5. Prevent rain from directly running off a roof onto the heat pump. Install proper drainage.
6. Do not use the heat pump if it has been flooded. Immediately contact a qualified technician to inspect
the heat pump and repair it if should prove necessary.
19
6. Maintenance and inspection
6.1 Maintenance
Check the water inlet and drainage often. The water and air inflow into the system should be sufficient
so that its performance and reliability does not get compromised. You should clean the pool filter
regularly to avoid damage to the unit caused by clogging of the filter.
The area around the unit should be spacious and well ventilated. Clean the sides of the heat pump
regularly to maintain good heat exchange and to save energy.
Check if all processes in the unit are operational and pay special attention to the operation perssure of
the refrigerant system.
Check the power supply and cable connections regularly. Should the unit begin to function abnormally
or should you notice a smell from an electrical component, arrange fro timely repair or replacement.
You should also purge the water if the unit will not work for an extended period of time. You should
check all parts of the unit thoroughly and completely fill the system with water before turning it on
again afterwards.
Improper installation may result in an electrical discharge that could lead to death of-or serious injury
to-pool users, installers or others due to electrical shock and may also cause damage to property.
DO NOT attempt to modify the internal configuration of the heat pump.
1. Keep your hands and hair clear of the fan blades to avoid injury.
2. If you are not familiar with your pool filtering systems and heat pump:
a. Do not attempt to adjust or service without consulting your dealer or your professional pool or air
conditioning contractor.
b. Read the entire installation and user manual before attempting to use, service or adjust the unit.
C. Start the heat pump at least 24 hours after its installation in order to prevent damage to the compressor.
6.2 Trouble shooting guide
Note: Switch off the power prior to maintenance or repairs.
IMPORTANT REMARK: if a malfunction can not be resolved immediately, in order to analyse the
problem itself, we will need to know the message(error code) that is displayed on the controller, as
well as the values for the settings (parameter 00-10 for LCD display while parameter 0-A for LED
display) and for status of the heat pump (a mbient te mpe rature, w ater inle t/ outlet tem per atu re
and system coil temperature) just before the failure or, if this is impossible, just after it.
Please keep this information at hand when calling customer service.
