1.1 Packaging
• 1 box: Outdoor unit.
• 1 box: Hydraulic module with gas generator
and outdoor temperature sensor.
1.4 Denitions
- Split : The heat pump is formed by two elements (an
outdoor unit to be installed outdoors and a hydraulic
module to be installed indoors).
- Air/water: The outdoor air is the energy source. This
energy is transmitted to the heating water by the heat
pump.
- Inverter: The speed of the fan and the compressor
are modulated to suit the heat requirements. This
technology economises energy and permits operation
with single phase power supply, regardless of the
power rating of the heat pump, by avoiding high current
demands when started.
- COP (coefcient of performance): this is the ratio
between the energy transmitted to the heating circuit
and the electrical energy consumed.
- Hybrid: the hydraulic module operates with dual
energy (air/water heat pump and built in gas boiler).

1.7 Operating principle
The heat pump transmits the energy in the outdoor air to
the home to be heated and the production of domestic
hot water.
The heat pump is formed of four main elements inside
which a refrigerating uid circulates (R410A).
- In the evaporator (item 13,gure 6, page 11):
The calories are taken from the outdoor air and
transmitted to the refrigerating uid. As its boiling point
is low, it changes from the liquid state to the vapour
state, even when the weather is cold.
- In the compressor (item 10 or 16,gure 6, page 11):
The vaporised refrigerating uid is pressurised and
thus carries more calories.
- In the condenser (item 3,gure 7):
The energy of the refrigerating uid is transmitted to
the heating circuit. The refrigerating uid returns to its
liquid state.
- In the pressure regulator (item 9or 15,gure 6, page 11):
Then liqueed refrigerating uid is reduced to low
pressure and its initial temperature and pressure.
The heat pump has a regulator that controls the
indoor temperature based on the measurement of
the outdoor temperature, regulation by water logic.
The ambient sensor (optional) provides a corrective
action to the water logic.
The hydraulic module is equipped gas generator which
operates at the request of the regulator:
- to provide additional heating during the colder
periods,
- to reach the DHW comfort value
- to provide a relay during "Peak rate" days
(load shedding or EJP function).
Priority is given to the operation of the heat pump.
When the heat pump is not sufcient for the heating, the
gas generator automatically takes over.
Leakproof type appliance (C13, C33).
The new air needed for combustion is taken from
outside the horizontal or vertical terminal and is then
aspirated into the boiler through the pipes (concentric
or separate).
Separate pipe adaptor (C53)
Conguration possible only in boiler room.
Chimney type appliance (B23, B23P)
The new air needed for combustion is taken from the
room where the appliance is installed.

• Regulation functions
- The initial temperature of the heating circuit is
controlled by water logic.
- In function of an initial heating temperature, the power
of the outdoor unit is modulated via the "inverter"
compressor.
- Management of the supplementary heating.
- The daily timer programme allows comfort or reduced
ambient temperature periods.
- Switching between summer/winter operation is
automatic.
- Ambient sensor*: The ambient sensor provides a
corrective action to the water logic.
- Management of a 2nd heating circuit*.
- Domestic hot water: Hourly heating programme,
management of the comfort temperature and the
reduced temperature.
*When the heat pump is equipped with options and associated kits.
• Protection functions
- Anti-legionella cycle for the domestic hot water.
- Tank anti-corrosion protection by titanium anode (ACI).
- Antifreeze protection for the installation, DHW, etc.
• Hydraulic pressure monitoring
A pressure switch monitors the hydraulic pressure. If
the pressure is lower than:
- 0.5 bars: Safety
- 0.8 bars: Power reduction and information on the display.
• Miscellaneous
- Start and return temperature monitoring.
- Smoke temperature monitoring.
• Operating principle of the domestic hot water
(DHW)
DHW production takes priority over heating.
Two domestic hot water (DHW) temperatures may
be set: comfort temperature (line 1610 at 55 °C)
and reduced temperature (line 1612 at 40 °C).
The default DHW programme follows the hourly heating
programme with 1 hour's advance on start-up.
Depending on the parameter setting (1620), the comfort
temperature may be reached 24 hours / day or according
to the DHW programme.
The reduced temperature value may be useful to avoid
restarting the DHW too many times and for too long
through the day.
The production of domestic hot water (DHW) is started
when the temperature in the tank is 7°C below (setting
of line 5024) the reference value temperature.
The domestic hot water (DHW) is produced by the heat
pump and the boiler top-up.
A switching function of "reduced" to "comfort" is
available on the front panel of the user interface
(see item 1,gure 51, page 46).
Anti-legionnella cycles may be programmed.
• Fan coil units with integrated regulation
Do not use an ambient sensor in the zone concerned.

2 Installation
2.1 Installation and maintenance rules
The appliance must be installed and the maintained
by an approved professional in accordance with the
prevailing regulations and code of practice, in particular:
- The legislation on the handling of refrigerants.
- Heating installation with oor heating system.
- Low voltage electrical installations - Rules.
2.2 Unpacking and reserves
2.2.1 Reception
When the courier is present, carefully check the general
appearance of the appliances, check that the outdoor
unit has not been in horzontal position. In the event
of disagreement, write to the courier within 48 hours
mentioning all reserves and send a copy of this letter to
the After Sales Department.
2.2.2 Handling
The outdoor unit must not be in horizontal position during
transport. Transport in a horizontal position creates risk
of damage to the appliance by moving the cooling uid
and damaging the compressor's suspension.
Damage caused by transport transport in horizontal
position is not covered by the warranty.
If required, the outdoor unit may be tilted only when
being moved by hand (to get it through a doorway, or
up stairs...). This operation must be carried out carefully
and the appliance must be immediately returned to the
vertical position.

2.2.3 Containment of refrigerant circuits
All refrigerant circuits fear contamination from dust and
moisture. If such pollutants introduced into refrigeration
circuit, they can contribute to degrade the reliability of
the heat pump.
"It’s necessary to ensure correct containment
connections and refrigerant circuits (hydraulic
unit, outdoor unit).
"In case of subsequent failure and expertise, the
nding of the presence of moisture or foreign
objects into the compressor oil would lead to
systematic exclusion of warranty.
- Check upon receipt that the ttings and the refrigeration
circuit caps mounted on hydraulic unit and outdoor unit
are properly seated and locked (impossible to loosen
bare hands). If this’s not the case, tighten them using
an against wrench.
- Check also that the refrigerant connections are sealed
(plastic caps or tubes crushed at the ends and soldered).
If the caps must be removed during installation (tubes
cut by example), put back them as soon as possible.

2.3 Positioning
The choice of the position is particularly important
as having to move it later is a delicate operation that
requires a qualied person.
Choose the position of the outdoor unit and the hydraulic
module after discussion with the client.
Respect the max. and min. distances between the
hydraulic module and the outdoor unit (gure 24, page 26),
as the performances and life of the system depend on this.
2.4 Installing the outdoor unit
2.4.1 Installation precautions
"The outdoor unit must only be installed
outdoors. If a shelter is required, it must have
large apertures on all 4 sides and respect the
space required for the installation (single phase
model or three phase model gure 13)
• Prefer a sunny location, sheltered from strong and
cold dominant winds.
• The appliance must be completely accessible for
subsequent installation and maintenance work (gure
13).

become dirty or have excessive water dripping onto it
(under a leaky drainpipe for example).
• When operating water may escape from the outdoor
unit. Do not install the appliance on a terrace; install it
at a location which is drained (bed of gravel or sand).
If installed in a region where the temperature may be
below 0°C for a long period, check that the ice does not
cause any danger. It is also possible to connect a pipe to
evacuate to the outdoor unit (gure 14).
• No obstacles must obstruct the circulation of
air through the evaporator and the fan outlet
(single phase or three phase model gure 13).
• Keep the outdoor unit away from sources of heat or
inammable products. Contact your energy distributor
for the installation constraints.
• Ensure that the appliance does not disturb neighbours
or users (noise level, draughts caused, low of the air
blown causing a risk of freezing plants in its path).
• The surface on which the outdoor unit is tted must:
- Be permeable (earth, gravel bed...),
- Support the weight comfortably,
- Permit it to be solidly attached,
- Not transmit any vibration to housing (anti-vibration
posts are available as accessories).
• The wall bracket can not be used in conditions likely to
transmit vibrations, ground position is preferred.
2.4.2 Fitting the outdoor unit
The outdoor unit must be raised by at least 50 mm
from the ground. In snowy regions, this height must be
increased but must not exceed 1.5 m (gure 14).
- Attach the outdoor unit using screw and spring or split
washers to ensure they do not come loose.
"Warning
In regions with heavy snowfall, if the outdoor unit's
entrance and exit are blocked by snow it may be difcult
to heat up and may probably cause a breakdown.
Build an awning or place the appliance on a tall support
(local conguration).
- Put the appliance on a solid support to minimise
impact and vibration.
- Do not place the appliance directly on the ground as
this may cause problems.
2.4.3 Connecting the condensate evacuation pipe
(see gure 14).
If an evacuation pipe must be used:
- Use the elbow provided (C) and connect a exible
hose of 16 mm diameter to evacuate the condensates.
- Use the plug(s) supplied (B) to obstruct the orice of
the condensate tray.
Fit so that gravity ow of the condensates is ensured
(waste water, rainwater, gravel bed).
"If the appliance is installed in a region where
the temperature may fall below 0 °C for long
periods, t the evacuation pipe with a resistance
trace to avoid it icing over. The resistance trace
must heat not just the evacuation pipe but also
the bottom of the condensate drip tray of the
appliance.

2.5 Installing the hydraulic module
2.5.1 Room where to install
• The room where the appliance operates must respect
the regulations in force.
This equipment may not be installed in a bathroom
or a shower room.
The atmospheric conditions in the room must not be
humid; humidity is damaging for electrical appliances.
If the ground is humid or soft, use a base of sufcient
height.
• To facilitate the servicing operations and permit access to
the various parts, it is recommended that sufcient space
be left all around the hydraulic module (gure 15).
• If necessary, install the hydraulic module on anti-
vibration posts or any other resilient material to limit
the sound level caused by vibration.
• Room-sealed ( turbo) pipe (C13, C33)
As the appliance is leakproof, no specic precautions
are required concerning ventilation of the premises.
• With Separate pipe adaptor (C53)
Conguration possible only in boiler room.
• With chimney adaptor (B23, B23P)
The appliance must be installed in a suitable and
well ventilated room. The room must have a fresh
air inlet (A) with a free non-blockable cross section

section of at least 100 cm2 positioned in the upper
part and opening directly outdoors (see gure 15).
The air renewal volume must be at least (P(kW) x 2) m3/h,
i.e. 48 m3/h.
The warranty on the heater will not cover any installation
of the appliance in a chlorine rich atmosphere
(hairdressers, launderette, etc.) or any other corrosive
vapours.
• Be careful of the presence of inammable gas close
to the heat pump when it is installed, especially
when brazing is required. The appliances are not
antiexplosion and must therefore not be installed in an
explosive atmosphere.
- To avoid condensation inside the condenser, remove
the refrigerant circuit caps only when building the
refrigerant connections.
- If the refrigerant connection only occurs at the end of
the installation, be sure that the refrigerant circuit caps*
remain in place and tight throughout the installation
duration.
* (hydraulic unit side and outdoor unit side)
- After every intervention on the refrigeration circuit and
before nal connection, take care to replace the plugs
in order to avoid any pollution from the refrigeration
circuit (The sealing with tape is prohibited).
