• drain the water condenser (risk of freezing) by removing the two pool wa-
ter inlet and outlet connections at the back of the heat pump,
• in the case of a full winterizing of the pool: connect the inlet and outlet con-
nections “lightly” without tightening (one turn) in order to avoid foreign
bodies entering into the condenser,
• in the case of winterizing the heat pump alone: do not reconnect the inlet
and outlet connectors, instead place two stops (supplied) on the condenser
water inlet and outlet.
To avoid damaging the appliance with condensation, do not cover it with an
air-tight cover.

Maintenance
3.1 Maintenance instructions
A general servicing of the appliance is recommended both when winter-
izing and when restarting in order to ensure the proper operation of your
heat pump, to preserve its performance and to prevent potential failures.
Servicing costs will be borne by the user.
• ensure that no foreign bodies obstruct the fan grid,
• clean the inside of the appliance, do not use solvent-based cleaning products,
• clean the evaporator (for placing see§ “Dimensions” in appendix) with a soft
brush and a fresh water hose (disconnect the power cable), do not twist or
bend the metal blades,
Do not use a high-pressure water hose.
• check the correct operation of the regulator,
• check that the condensation is drained properly whilst the appliance is oper-
ating.
The following operations must be performed by a qualifi ed technician:
• check the correct working condition of all safety components,
• check that all metal elements are earthed,
• check the tightening and connections of the electric cables and the cleanli-
ness of the electrical equipment box,
Incorrectly tightened terminals may cause overheating of the electri-
cal terminal rail, and will void the guarantee.

FAQ
Is it possible to improve the temperature performance?
A heat pump is designed to extract heat from the surrounding air and trans-
fer it to the pool water. The higher the air temperature, the more heat the
heat pump will be able to transfer to the pool water.
In order to improve the effi ciency of your heat pump it is recommended
that you:
• protect the pool with a cover (fl oating cover, roller cover …), so as to avoid
heat loss,
• choose periods when the outside temperature is mild (> on average 10° C)
in order to facilitate the temperature increase (this may take several days.
The actual time will vary according to weather conditions and the power of
the heat pump),
• the higher the surrounding air temperature, the more effi cient the heat
pump will be.
Check that the fi ltration time is suffi cient:
• during the heating phase, water circulation must be continuous (24h/24),
• maintain the temperature throughout the season, allow for an “automatic”
circulation of at least 12 hrs/day (the longer this time is, the more time the
heat pump will have to function and to heat the water).
Setting the setpoint to maximum will not heat the water any faster.
Why is my heat pump not heating?
Several reasons could explain this situation:
1. At start-up the appliance remains on “pause” for 30 seconds before actually
starting up: check that this time has passed,
2. once the pool has reached the required temperature, the heat pump switches
off: check that the water temperature is lower than the requested tempera-
ture (see §2.4),
3. when there is no water fl ow or when it is insuffi cient, the heat pump will stop:
check that water is fl owing correctly through the heat pump, via an external
circulation system, that the pipework connections are correct and check that
the “water fl ow” diode is lit and not fl ashing,
4. when the outdoor air temperature drops below 7°C, the heat pump will stop:
check the outdoor temperature as well as the “surrounding air temperature”
indicator
5. The heat pump may have detected a malfunction: check to see if an error
code is displayed on the screen, if so refer to §4.
If the problem persists after you have checked all the above points, contact
your retailer.

The heat pump is giving off water: is this normal?
Your appliance will give off water in the form of condensation. This water is
the humidity contained in the air which condenses on contact with certain
cold components inside the heat pump.
Caution: your appliance can drain several litres of water per day.
Where should my water treatment system be positioned
with respect to the heating system?
The water treatment system (chlorinator, salt chlorinator, etc…) must be
installed preferably downstream from the heat pump (see installation
§1.3.3), and must be compatible with the latter (check with the manufac-
turer).
Technical information
Before working on the appliance, ensure that it is disconnected from the
power supply.
Do not vent R410A into the atmosphere: R410A is a fl uorinated greenhouse
gas, covered by the Kyoto Protocol, with a Global Warming Potential (GWP)
= 1975 - (Directive of the EC 842/2006).
Removing or shunting any of the appliance’s safety elements will automati-
cally void the warranty. Use only original manufacturer parts when replac-
ing faulty or worn parts.
