I. Performance and properties
High performance
Our heat pumps are very effi cient in transferring heat from air to water in the pool. They can provide savings
of up to 80% in energy compared to an electric heater.
Long life
The heat exchanger is made from a PVC/titanium composite pipe resistant to the long-term effects of pool
water.
Simple operation and maintenance
The device is easy to control: switch it on and set the required temperature of the water in the pool. The
system incorporates a microcomputer control unit which allows all the operational parameters to be specifi ed.
The state of operation can be displayed on the control unit through an LCD display.

(energy collector)
• Heat pumps make use of free heat from the sun by collecting and absorbing energy from the outside air.
• This device contains a ventilator which draws the outside air in and makes it fl ow over the surface of the
EVAPORATOR (energy collector). The liquid coolant in the EVAPORATOR pipeline absorbs the heat
from the outside air and the coolant vaporises.
• The warm gas in the pipeline passes through the COMPRESSOR which gathers the heat and increases the
temperature to generate very hot gas which then passes to the CONDENSER (water heat exchanger). This
is where the heat exchange occurs - the hot gas transfers heat to the colder water from the pool which is
circulating through the coil.
• The pool water is heated and the hot gas is cooled when passing through the CONDENSER pipeline
– it regains its liquid form and, after the passage through the CAPILLARY TUBE, the whole process
recommences.
• The current technology used in the heat pump allows effi cient use even at an outside air temperature of 7 to 10 ºC.
For tropical and subtropical climates, this means that 26 to 32 ºC may be maintained in the pool under almost any
conditions all year round. In northern countries, the heat pump considerably extends the swimming season.

V. Preparations for installation
5.1 Selection of the installation position
• The heat pump has to be installed in a spacious and well ventilated place.
• Its position has to guarantee adequate free space for the exhaust (the location of the air inlet is shown
in the diagram on the next page).
• The heat pump has to be situated close to a drain or vent so as to make water discharge easier.
• The installation base or brace has to be fi rm enough to ensure smooth operation of the device.
• Make sure the device, when installed, is situated vertically, without any inclination.
• Do not install the device in places where there is contamination, corrosive gas or where dirt or fallen
leaves accumulate.
• The heat pump must not be installed in the vicinity of an infl ammable or explosive environment or
near things that are a common cause of fi re.
• Maintain the distances from obstacles as indicated with arrows in the picture below.

VIII. Maintenance
• Check that the device water inlet is open. It is necessary to avoid low water and air fl ows into the device
because they could worsen its performance and reliability. You have to clean the swimming pool fi lter
regularly to avoid damage to the device as a result of a dirty or blocked fi lter.
• The space around the device has to be dry, clean and well ventilated. Clean the side heat exchanger regularly
in order to maintain good heat exchange performance and save energy.
• The cooling system may only be serviced by certifi ed maintenance engineers.

* Notes: One minute after its activation, the water pump starts measuring the temperature of the input and output water.
If the difference in temperatures is higher than 13ºC for 10 seconds, the electronics will stop the heat pump and the control unit
will display fault PP6; after three minutes the heat pump will start again. If it stops three times in 30 minutes because of fault PP6,
the control unit will display fault EE5. It will be possible to start the heat pump again only after disconnecting and re-connecting the power supply. When
the pump is not operating or the device is in heating mode, the system does not monitor abnormal temperature differences.

WARNING
• Before installation, check that the electricity supply complies with the technical conditions of your heat
pump. The details are specifi ed on the plaque fi tted to the device or in this guide.
• Install recommended electric protective devices in accordance with local regulations.
• The heat pump has to be earthed to protect you from electric shocks due to possible short circuits.
• This guide includes a wiring diagram.
• For safety reasons, do not make any unauthorised changes to the heat pump or carry out repairs to the
device without authorisation.
• Do not insert any objects into the pump when it is operating as they might touch the ventilator and
damage it or cause accidents (especially in the presence of children).
• Do not use the heat pump without a grille or protective plate as this could result in accidents or abnormal
operation of the device.
• If water gets into the device, immediately contact the supplier. The device may be used again only after
examination by our technicians.
• Unauthorized technicians may not adjust the sensors, valves or control units of the device.
