1 Instructions to be read before using the equipment
Please comply with the following instructions in order
to avoid any risk of injury or inappropriate use of the
appliance.
1.1 Safety instructions
1.1.1 Start-up
" Do not switch the appliance on until every
llings have been done.
" Do not try to install this appliance yourself.
" This heat pump requires an appropriately
qualied person to install it.
" The installation must always be connected to
the Earth and tted with a protective circuit
breaker.
" Do not modify the electricity supply.
" The appliances are not reproof and should
therefore not be installed in a potentially
explosive atmosphere.
1.1.2 Use
" Do not let children insert foreign bodies into
the fan protection grill or climb on top of the
outdoor unit. The ns on the air exchanger are
extremely ne and cause cuts.
" Nothing should obstruct the air circulation
through the evaporator and from the fan.
" Do not climb on the top of the outdoor unit.
" The room in which the appliance is operating
must be correctly ventilated in order to prevent
any loss of oxygen if there is an escape of
refrigerant gas.
" Consult your Installer before making any
changes or modications to the premises where
the appliance is installed.
" Do not place any heat source under the room
control unit .
1.1.3 Maintenance
" Do not try to repair this appliance yourself.
" This appliance does not contain any components
capable of being repaired by the user himself.
Removing one or other of the covers can expose
you to dangerous electrical voltages.
" In any case, switching off the current is not
sufcient to protect you from any external
electrical shocks (capacitors).
" Do not open the outdoor unit or the hydraulic
unit while they are operating.
" Switch off the power supply if there are any
abnormal noises, smells or smoke coming from
the appliance and contact your installer.
" Switch off the power to the appliance before
you clean it.
" Do not use aggressive cleaning liquid or
solvents to clean the body work.
" Do not use a pressure washer to clean the
outdoor unit. This could damage the air
exchanger and the water might penetrate into
the electrical circuits.

1.2 Precautions and warnings regarding
your installation.
1.2.1 The outdoor unit
The outdoor unit contains the equipment for capturing
energy from the ambient air.
Your installer has placed this unit in a location that
enables it to operate in an optimum manner.
Nothing should obstruct the air circulation through the
evaporator and from the fan.
The control system for your heating system is designed
in ow temperature for the water based on the outdoor
temperature (water control).
In cold periods, this water freezes in contact with the
exchanger and is drained away by regular defrosting
cycles.
The control system automatically controls the defrosting
cycle, whose operation can lead to the quite normal
emission of steam.
1.2.2 The hydraulic unit
The hydraulic unit contains the heat pump complete
control system, in charge of controlling the heating
comfort level and the production of domestic hot water
(if the installation is tted with a DHW tank with electrical
back-up heating).
The heat pump is equipped with an electric back-up
system, which is designed to provide additional heat
during the coldest periods.
1.2.3 Control system
Your installer has carefully adjusted your installation. Do
not modify setting parameters without his agreement. If
in doubt, do not hesitate to contact him.
The control system for your heating system is designed
in ow temperature for the water based on the outdoor
temperature (water control).
The installation of a room thermostat (option) allows to
improve operation of the regulation (the inuence of the
room temperature is taken into account).
1.2.4 Fan convectors with integrated control system
Do not use a room sensor in the area.
1.2.5 The radiators
To ensure the function of the regulation with room
inuence, it's necessary that the room in which the room
thermostat is installed has no thermostatic valve or that
they must be completely open.
1.2.6 Floor-heating systems
New oor-heating systems require to be initially heated
slowly to avoid any problems with cracking. Check
with your installer that this initial heating procedure
has indeed been performed before using your heating
system freely.
To be efcient, 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.
The great stability in a regulation system for oor-heating
systems avoids sharp differences in temperature.
However, this stability involves a reaction time of the
order of several hours, (approx 6 hours).
Any changes to the setting must be made slowly, leaving
the installation time to react. Adjusting the system to
exaggerated setting or in an untimely manner always
results in signicant temperature uctuations during
course of the day.
Similarly if your dwelling has a oor-heating system,
do not reduce the heating or switch it off if you will be
absent for a short period. The reheating period is always
quite long (approx 6 hours).
1.2.7 Domestic hot water (DHW)
This function is designed as an option through the use
of a DHW tank with electrical backup heating.
When the DHW production is required, the heat pump
adapts to this demand with higher priority.
No space heating is produced while the domestic hot
water is being prepared.
Domestic hot water (DHW) is produced by the heat
pump and then topped up, if necessary, by electrical
backup heating or the boiler.
To ensure a DHW setting over 45°C, the electrical
backup heating or the boiler must be left on.
The electrical backup heating enables anti-legionella
cycles to be conducted efciently.

2 Overall view of the installation
Your heat pump has been congured by your installer. It
is composed of the following main elements :
- The outdoor unit is positioned, as its name indicates,
outside your dwelling and extracts energy from the
outside air.
- The hydraulic unit positioned in your boiler room, cellar,
garage or even your kitchen, transfers the energy to
the heating circuit (and the domestic hot water).
- The outdoor sensor detects the outdoor temperature.
Optional equipment :
- Room thermostat.
- Room control unit.
Heat pumps are systems that can be connected to any
form of low temperature heat distribution systems : the
heat captured by the heat pump can therefore be used
in different ways :
- Floor-heating systems.
- Radiators or fan coil heaters.
- Domestic hot water (DHW).
