Do not climb on top of the outdoor unit.
The appliance must be installed in an appropriate and well-ventilated room.
If your installation location already meets safety standards, do not carry out any modications
(ventilation, ue gas evacuation, openings, etc.) without the advice of your installation
engineer.
Avoid making excessive amounts of dust in proximity to the burner, especially when it is
in operation.
Do not insert anything into the burner fan.
Do not place any heat source under the remote control.

Maintenance
Do not try to repair the appliance yourself.
This appliance does not contain any components which can be repaired by the user.
Removing either of the covers can expose you to dangerous electrical voltages.
In any case, switching o󰀨 the current is not su󰀩cient to protect you from any external
electrical shocks (condensers).
Do not open the outdoor unit or the hydraulic unit while they are in operation.
If you hear unusual noises, smell smoke or other odours coming from the appliance, turn
o󰀨 the power and contact your installation engineer.
Any modication of a sealed component is forbidden.
This appliance requires:
Qualied personnel possessing a certicate of competence for handling refrigerants
are required for performing maintenance work on the outdoor unit and checking the
refrigeration circuit.
A heating installer is required for maintenance of the burner and the chimney (or room-
sealed pipe).

Overview of the installation
Your heat pump has been congured by your installation
engineer. It is made up of the following main parts:
- The outdoor unit, as its name suggests, is placed
outside your dwelling, and extracts energy from the
outside air.
- The hybrid hydraulic unit is located in your boiler room,
cellar or garage, and transfers energy to the heating
and domestic hot water circuits.
- The outdoor sensor monitors the outdoor temperature.
Optional:
- Room sensor(s).
- Room control unit or wireless remote control.
Hybrid heat pumps are systems which can be connected
to any type of radiator, and the heat captured by the
heat pump can be used in di󰀨erent ways:
- Radiators (high, medium, low temperature) or fan-
coils.
- Underoor heating system.

Precautions and warnings
about your installation
▼
Outdoor unit
This unit was installed by your installer in a location
where it is able to operate most e󰀩ciently.
Nothing should obstruct air circulation
through the evaporator and out from the fan.
In the outdoor unit, the surrounding air is cooled through
contact with an exchanger. The water contained in the
air may condense and ow out of the outdoor unit. The
outdoor unit can generate a large volume of water called
condensate.
In cold weather, this water freezes on contact with the
exchanger and must be regularly removed using the
defrosting cycles. The defrosting cycle is managed
automatically by the control system and can produce
steam emissions which are completely normal.
▼
Hydraulic unit
The hydraulic unit contains the appliance's control
system which manages the room temperature and the
production of domestic hot water.
The hydraulic unit is dual energy (air/water heat pump
and integrated fuel oil boiler).
Oil: Your appliance is equipped with a burner
which uses domestic oil (heating fuel oil). The
oil must be free of impurities and of water.
▼
Control system
Your installer has carefully adjusted your
installation. Do not change the settings without
their consent. If in doubt, do not hesitate to
contact them.
Your heating system is controlled by adjustment in
relation to the outdoor temperature (temperature
control).
The installation of a room sensor (optional) makes
it possible to improve the operation of the control
system (inuence of the room temperature is taken into
account).
▼
Fan-coils with integrated control system
Do not use a room sensor in the area in question.
▼
Radiators
If the radiators are equipped with thermostatic
valves, they must be fully open.
▼
Underoor heating system
• A new underoor heating system must initially be
heated slowly to avoid any problems of cracking.
Check with your installer that this initial heating
procedure has indeed been performed before freely
using your heating system.
• To be e󰀩cient, underoor heating systems do not
need to be very hot and never should be. At most, the
systems should be warm to the touch in cold weather.
• An underoor heating system's signicant heat inertia
prevents sudden room temperature di󰀨erences.
However, this intertia involves a reaction time of
several hours (approx 6 hours).
Any changes to the setting must be made
slowly, leaving the installation su󰀩cient
time to react. Any exaggerated or abrupt
adjustments to the settings always result in
signicant temperature uctuations during
the day.
• Similarly, if your dwelling has an underoor heating
system, do not reduce the heating or switch it o󰀨 if
you will be absent for only short periods. The reheating
period is always quite long (approx 6 hours).
▼
Domestic Hot Water (DHW)
When hot water is required, the heat pump
adapts its priority to meet the demand.
No space heating is produced during the
preparation of domestic hot water.
The HP produces the DHW, which is then additionally
heated, if required, by the boiler.
The boiler allows Legionella cycles to be run e󰀨ectively
(ask your engineer if this function is activated).

▼
Checking the outdoor unit
Remove any dust from the exchanger, if necessary,
while making sure not to damage the blades.
Check that there is nothing blocking the air ow.
▼
Checking the refrigeration circuit
If the amount of refrigerant in the system exceeds 2
kg (models > 10 kW), the refrigeration circuit must be
checked annually by an approved engineer (they must
have a certicate of competence for the handling of
refrigerants). Consult your heating engineer.
►
End-of-life of the appliance
The appliances must be dismantled and recycled by
a specialised service. The appliances must not, under
any circumstances, be thrown out with household waste,
bulky waste or at a tip.
At the end of its service life, please contact your installer
or local representative to proceed with its dismantling
and recycling.
Maintenance operations must be done regularly to
ensure the appliance operates in total safety.
Depending on the operating conditions, boiler and
burner must be cleaned and inspected once or twice
a year.
The room-sealed pipe should be checked and cleaned
regularly by a specialist (once per year).
These operations must be performed by a specialist
who will also check the boiler's safety devices and
installation.
Clean all the enamelled panels of the casing with a dry
or slightly damp soft cloth.
Do not use abrasive cleaners.
►
Regular checks
The burner should always be switched on.
No ue gases from the boiler and the chimney should
be released into the boiler room when the burner is in
operation.
Fuel oil consumption and tank condition should be
monitored in order to detect any leaks immediately.
Every year, clean the lter installed on the burner’s oil
supply.
In case of an incident, switch o󰀨 the main power supply
as well as the oil valve and call your heating engineer.
►
Boiler room, hydraulic unit and
heating system
▼
Hydraulic unit
The boiler and the burner should be cleaned and
checked once a year.
These operations must be performed by a specialist
who will also monitor the safety devices of the hydraulic
unit and installation.
▼
Hot water tank
Maintenance on the tank must be carried out annually
(frequency may vary according to water hardness).
Consult your heating engineer.
▼
Verication of installation lling
The pressure when cold and when stopped must be 1.5
bars.
If the pressure is below 0.5 bar, increase the pressure
by operating the lling valve.
If relling and a pressure reset are necessary, check
what type of uid was used initially.
If in doubt, contact your installer.
If frequent rells are required it is absolutely
essential that you check for any leaks.
