■ Installation and maintenance rules
The appliance must be installed and maintained
by an approved professional in accordance with
current regulations and codes of practice.
• Do not use any means to accelerate the
defrosting process or to clean the appliance,
other than those recommended by the
manufacturer.
• The appliance must be stored in a room that
does not contain continuously operating
ignition sources (for example: open fl ames,
gas appliance or operating electric heater).
• Do not pierce or burn.
• Be careful, refrigerants can be odorless.
■Handling
The outdoor unit must not be placed in a horizontal
position during transport.
If not kept upright during transport, the appliance
could be damaged through displacement of
the refrigerant and damage to the compressor
suspensions.
Any damage caused by transportation in a horizontal
position is not covered by the warranty.
If necessary, the outdoor unit may be tilted only
during manual handling (to go through a door or to
take a stair). This operation must be conducted very
carefully and the appliance must be immediately
restored to the upright position.
■Installation
The heat pump installation must meet the
requirements related to the location of the heat
pump.
The heat pump is designed to be installed at less
than 2000 m altitude.
In accordance with IEC 60-335-2-40 standard, the
hydraulic module of the heat pump as well as all
the refrigerant connections that cross the inhabited
area must be installed in rooms respecting the
minimum surface.
• Warning, hydraulic unit should not be installed
in an air current.
■Refrigerant
The maximum load of R32 fl uid with supplements
must not exceed 1.84 kg.
■Containment of refrigeration circuits
All refrigeration circuits are sensitive to dust and
moisture contamination. If any such pollutants
penetrate the refrigeration circuit, they can aff ect
the reliability of the heat pump.
• Make sure that the connections and
refrigeration circuits (hydraulic unit, outdoor
unit) are protected correctly.
• In the event of a subsequent failure and
following an inspection, the presence of
moisture or foreign bodies in the compressor
oil would automatically void the warranty.
- Check upon receipt that the fi ttings and refrigeration
circuit caps mounted on hydraulic unit and outdoor
unit are properly seated and secured (cannot be
loosened with bare hands). If this is not the case,
tighten them using a C spanner.
- Check also that the refrigeration connections are
sealed (plastic caps or tubes crimped at the ends
and brazed). If the caps must be removed during
the installation (tubes to be re-cut for example),
put them back as soon as possible.
■Hydraulic connections
The connection must comply with industry standard
practice according to current regulations.
Reminder : Seal everything when fi tting in
accordance with industry standard practice for
plumbing work:
- Use suitable seals (fi bre gasket, O-ring).
- Use Tefl on or hemp tape.
- Use sealing paste (synthetic depending on the
case).
Use glycol/water mix if the minimum fl ow
temperature is set below 10°C. If you are using a
glycol/water mix, arrange for an annual check on
the quality of the glycol. Use monopropylene glycol
only. The recommended concentration is 30%
minimum. Never use monoethylene glycol.
• In some installations, the presence of diff erent
metals can cause corrosion problems;
the formation of metal particles and sludge can
appear in the hydraulic circuit.
• In this case, it is advisable to use a corrosion
inhibitor in the proportions indicated by the
manufacturer.
• You must also ensure that treated water does
not become corrosive.
On the cold water inlet, place a safety valve
calibrated to between 7 and 10 bar max. (depending
on local regulations) and connected to a drain
pipe leading to the sewer. Operate the safety
valve according to manufacturer's specifi cations.
The domestic hot water tank must be fed with cold
water passing through a safety valve. There must
be no other valves between the safety valve and
the tank.
■Electrical connections
Before performing any maintenance, make sure
that all power supplies have been cut off .
• Specifi cations of electricity supply
The electrical installation must be carried out in
accordance with current regulations.
Electrical connections will only be made once all
other installation operations (fastening, assembly,
etc.) have been completed.
Warning!
The contract signed with the energy provider must
be suffi cient not only to cover the heat pump’s power
requirements but also the combined sum of all the
appliances likely to be operating at the same time. If
the power is too low, check the power rating stated
in your contract with your energy provider.
Never use a power socket for the power supply.
The heat pump must be supplied directly with power
(without external switch) by special protected leads
from the electric panel via dedicated bipolar circuit
breakers, C curve for the outdoor unit, C curve for
the electrical heating* and domestic water backups*.
The electrical installation must be fi tted with a 30mA
RCD.
This appliance is designed to operate using a
nominal voltage of 230 V +/- 10%, 50 Hz.
• General remarks on electrical connections
It is essential to maintain neutral-phase polarity
when making electrical connections.
Rigid wires are preferable for fi xed installations,
particularly in a building.
Tighten the cables using the cable glands to
prevent the power cables from being accidentally
disconnected.
The earth connection and its continuity must be
ensured.
The earth wire must be longer than the other wires.
• Cable glands
To ensure the stability of power (Low Voltage) and
sensor (Extra-Low Voltage) cables, it is essential
that the cable glands are tightened according to the
following recommendations:

Operating principle
The heat pump transmits the energy contained in the
surrounding air into the dwelling to be heated.
The heat pump consists of four main elements, in which
a refrigerant (R32) circulates
- In the evaporator (ref. 12, fi g. 8, page 12) :
The calories are taken from the outside air and
transmitted to the refrigerant. Because it has a low
boiling point, it changes from a liquid to a vapour, even
in cold weather (down to -25°C outside temperature).
- In the compressor (ref. 9, fi g. 8, page 12) :
The vaporised refrigerant is pressurised and takes on
even more calories.
- In the condenser (ref. 15, fi g. 9, page 13) :
The energy of the refrigerant is transmitted to the
heating circuit. The refrigerant returns to its liquid state.
- In the expansion valve (ref. 8, fi g. 8, page 12) :
The liquefi ed refrigerant is returned to a low pressure
and regains its initial temperature and pressure.
The heat pump is equipped with a controller which
controls the room temperature based on the outdoor
temperature measurement. The room thermostat
(option) provides a corrective action for the temperature
control.
The hydraulic unit is fi tted with an electrical backup* or
boiler connection* which intervenes to provide additional
heat during the coldest periods.
■Control functions
- The heating circuit's fl ow temperature is controlled by
the temperature control.
- Depending on the heating fl ow temperature,
the outdoor unit's power is modulated by the "Inverter"
compressor.
- Control of the backup electrical heating.
- The daily timer program is used to set the periods
where the ambient temperature is comfortable or
reduced.
- Summer/winter time mode switchover is automatic.
- Management of the boiler backup*.
- Room sensor*: The room sensor provides a corrective
action for the temperature control.
- Control of a second heating circuit*.
- Domestic hot water: Heating timer program.
- Managing cooling*.
* Where the heat pump is fi tted with options and associated kits.
■Protective functions
- Anti-legionella cycle for domestic hot water.
- Anti-corrosion tank protection with titanium anode
(ACI).
- Frost protection: Frost protection cuts in if the heating
circuit's fl ow temperature falls below 5°C (provided
that the heat pump's electrical power supply is not
interrupted).

■Domestic hot water (DHW) operating principle
Two domestic hot water (DHW) temperatures can be
set: comfort and reduced.
The default DHW program is set to the comfort
temperature between 00:00 and 05:00 and between
14:30 and 17:00 and to the reduced temperature for the
rest of the day. This optimises electrical consumption
while ensuring comfortable water temperatures.
The reduced temperature setpoint may be useful to
avoid restarting the DHW too often and for too long
during the day.
The production of domestic hot water (DHW) is started
when the temperature in the tank drops to 7°C below
the temperature setpoint.
The heat pump produces the domestic hot water, which
is then additionally heated, if required, by the tank's
electrical backup or by the boiler. To ensure a DHW
setpoint over 55°C, the electrical backup heating must
be left on.
If the contract signed with the energy provider includes
a day/night tariff , the electrical backup is subject to the
supplier’s power tariff and the comfort temperature may
only be reached at night.
If no particular contract has been signed, the comfort
temperature can be reached at any time, including
during the day.
The production of DHW takes priority over heating;
nevertheless the production of DHW is managed
by cycles that regulate the amount of time assigned
to heating and production of DHW in the event of
simultaneous demand.
Anti-legionella cycles can be programmed.
■Fan convectors with integrated control system
Do not use a room sensor in the area in question.

Installation
►
Installation of refrigeration connections
Bend the pipes into position and make holes
for them through the fl oor or walls either with
their protective caps in place or after brazing.
Keep the protective caps in place or ends
brazed until the appliance is commissioned.
The outdoor unit must be connected to the
hydraulic unit ONLY with brand new separately
insulated copper connections (refrigerant quality).
Maintain the same pipe diameters (fi g. 32).
Observe the maximum and minimum distances
between the hydraulic unit and the outdoor unit
(fi g. 32, page 28) the guarantee of performance and
the service lifespan of the system depend on this.
The minimum length of the refrigeration
connections for correct operation is 3 m.
The appliance's warranty will be void if it is operated
with refrigeration connections less than 3 m long
(tolerance +/- 10%).
Ensure that the refrigeration connections are protected
from physical deterioration.

Installation precautions
The outdoor unit must only be installed
outside. If a shelter is required, it must have
broad openings on all 4 sides and installation
clearances must be observed.
• Choose the location of the appliance after discussion
with the client.
• We recommend choosing a site that is sunny but
sheltered from strong cold prevailing winds.
• The unit must be easily accessible for future installation
and maintenance work ( g. 16 and  g. 17, page 18).
• Ensure that connections to the hydraulic unit can be
made easily.
• The outdoor unit is able to withstand bad weather but
avoid installing it in a position where it is likely to be
exposed to signi cant dirt or  owing water (e.g. under
a broken gutter).
• Water may ow out of the outdoor unit when it is
operating. Do not install the outdoor unit on a paved
terrace; choose a well-drained location (e.g. gravel or
sand). If installation is carried out in an area where the
temperature stays below 0°C for long periods, check
that the presence of ice does not present any danger.
A drain pipe can also be connected to the condensate
drain pan (optional) ( g. 18, page 19).
• Nothing should obstruct the air circulation through the
evaporator and out from the fan ( g. 16 and g. 17,
page 18).
• Keep the outdoor unit away from heat sources and
ammable products.
• Make sure that the unit does not disturb the
surrounding area or inhabitants (noise level, draught,
low temperature of the ejected air freezing the plants
in its path.

• The surface on which the appliance is installed must:
- Be permeable (soil, gravel, etc.).
- Be perfectly fl at,
- Support its weight easily.
- Allow a solid fastening base,
- Not transmit any vibration to the dwelling. Anti-vibratory
blocks are available as an option.
• The wall bracket cannot be used where it is likely to
transmit vibrations. Installing the unit on the ground is
preferred.
▼
Positioning Outdoor Unit
The outdoor unit must be raised at least 50 mm above
ground level. In areas prone to snow, this height should
be increased but should not exceed 1.5 m
- Fasten the outdoor unit by means of screws and
rubber tightening or toothed lock washers to prevent
them from coming loose.
In areas with heavy snowfall, if the inlet and
outlet of the outdoor unit are blocked with
snow, heating may become diffi cult and a
failure is likely to occur.
Construct a canopy or place the unit on a high stand
(local confi guration).
- Place the unit on a solid stand in order to minimise
impacts and vibrations.
- Do not place the unit directly on the ground as this will
cause problems.
▼
Condensate drain pipe
The outdoor unit can generate a large volume
of water (called condensate).
If the use of a drain pipe is necessary (e.g., superposition
of the outdoor units) :
- Install the condensate drain pan (optional) for models
5, 6 & 8 only. Use the elbow provided and connect ©
a 16 mm-diameter hose for draining the condensate.
- Use the plug(s) provided B to block the opening of
the condensate drain pan (model 10).
Allow for the condensate to fl ow away under the force of
gravity (waste water, rain water, gravel bed).
If installation is carried out in an area where the
temperature stays below 0°C for long periods,
equip the drain pipe with trace heating to
avoid it icing up. Trace heating must heat not
only the drain pipe but also the bottom of the
appliance's condensate collection tank.
* In areas with heavy snowfall,
(H) must be higher than the average snow layer.

see page 24
▼
Installation precautions
• Choose the location of the appliance after discussion
with the client.
• The installation space should comply with current
regulations.
• To facilitate maintenance and allow access to the
various parts, we recommend that you provide
suffi cient space all the way around the hydraulic unit
(fi g. 19).
• Fix the hydraulic module to the ground (fi g. 22)
(fi xing system not supplied).
Other cautions
Be careful not to bring fl ammable gas
near the heat pump during installation,
in particular when brazing is required.
The appliances are not fi reproof and should
not therefore be installed in an explosive
environment.
To prevent risks of humidity in the exchanger,
it is pressurized with nitrogen.
- To avoid condensation inside the condenser, remove
the refrigeration circuit caps only when making the
refrigeration connections.
- If the refrigeration connection is only performed at the
end of the installation, make sure that the refrigeration
circuit caps* remain in place and tight throughout the
installation.
* (Hydraulic unit side and outdoor unit side).
- After each maintenance operation on the refrigeration
circuit and before the fi nal connection, take care to
put the caps back in position to avoid any pollution
of the refrigeration circuit (sealing with adhesive is
prohibited).

Shaping the refrigeration pipes
▼
Bending
The refrigeration pipes must be shaped only on a
bending machine or with a bending spring in order to
avoid any risk of crushing or breaking them.
Remove the insulation material from the section of
pipe to be bent.
Do not bend copper to an angle greater than 90°.
The radius of curvature must be more than
2.5x ø pipe.
Never bend pipes more than 3 times in the same
place otherwise traces of fracturing may appear
(hardening of the metal).
▼
Creating the fl arings
- Cut the pipe to an appropriate length with a pipe-cutter
without damaging it.
- Carefully deburr it, holding the pipe pointing downward
to avoid introducing fi lings into the pipe.
- Remove the fl ared connection nut situated on the
valve to be connected and slide the pipe into the nut.
- Proceed to fl are it, letting the pipe protrude out of the
fl aring tool's tube.
- After fl aring, check the state of the working radius (L).
This must not present any scratches or signs of
fracturing. Also check the dimension ( ).B

Checks and connection
The refrigeration circuit is very sensitive to dust
and humidity: check that the area around the
connection is clean and dry before removing the
plugs protecting the refrigeration connectors.
Indicated blowing value: 6 bar for minimum
30 seconds for connection of 20 m.
Checking the gas connection (large diameter)
1 Connect the gas connection to the outdoor unit. Blow
dry nitrogen into the gas connection and inspect its end::
- If water or impurities emerge, use a brand new
refrigeration connection.
2 Otherwise, proceed with fl aring and connect the
refrigeration connection to the outdoor unit immediately.
Checking the liquid connection (small diameter)
3 Connect the liquid connection to the hydraulic
unit. Blow nitrogen into the gas-condenser-liquid
connection system and inspect its end (outdoor unit
side).
- If water or impurities emerge, use a brand new
refrigeration connection.
- Otherwise, proceed with fl aring and connect the
refrigeration connection to the outdoor unit immediately.
Take particular care to position the tube
opposite its connector so as not to risk
damaging the threads. A properly aligned
connector can be attached easily by hand
without much force being required.
- Where necessary, connect an adapter (reducer)
1/4''- 3/8'' or 1/2''- 5/8'' (see fi g. 31, page 27)
- Comply with the indicated tightening torques.
(fi g. 31, page 27). If it is too tight, the fi tting may break
after a long period of time and cause a refrigerant leak.
►
Filling with gas
■see "Filling the installation with gas", page 72
Indicate on the label present on the outdoor
unit, the amount of gas (Factory + additional
fi lling) see fi g. 34.
If additional fi lling is required, do it before fi lling
the hydraulic unit with gas. Refer to paragraph
"Additional fi lling", page 30.
- Remove the access plugs (A) (fi g. 55, page 73)
from the valve controls.
- First of all fully open the liquid valve (small) and
then the gas valve (large) using an Allen (hex) key
(anti-clockwise direction) without using excessive
force against the stop.
- Quickly disconnect the hose from the .Manifold
- Refi t the 2 original caps (be sure they are clean) and
tighten them to the recommended tightening torque
indicated in the table fi g. 31, page 27. A seal is
achieved in the caps only with metal to metal.
The outdoor unit does not contain any additional
refrigerant allowing the installation to be bled.
Bleeding by fl ushing is strictly forbidden.
▼
Final sealing test
The sealing test must be carried out with a certifi ed gas
detector (sensitivity of 5g/year).
Once the refrigeration circuit has been gassed as
described above, check that all the refrigeration
connectors are gas-tight (4 connectors). If the fl arings
have been made correctly, there should be no leaks.
If necessary, check the seal of the refrigeration valve
caps.
If the event of a leak
- Return the gas to the outdoor unit (pump down).
The pressure should not drop below atmospheric
pressure (0 relative bar read on the ) so as not Manifold
to contaminate the recovered gas with air or moisture.
- Redo the connection,
- Restart the commissioning procedure.

Additional fi lling
The amount needed to fi ll the outdoor units corresponds to the maximum distances between the outdoor unit and
the hydraulic unit as defi ned here page 28. If the distances are greater, an additional amount of R32 is required.
For each type of appliance, this additional amount depends on the distance between the outdoor unit and the
hydraulic unit. Any additional fi lling with R32 must be carried out by an approved specialist.

Recovering the refrigerant in the outdoor unit
Before performing any maintenance, make sure that all power supplies have been
cut off .
Stored energy: after cutting off the power supplies,
wait for 10 minutes before accessing the internal parts of the equipment.
Perform the following procedures to collect the
refrigerant.
1- Switch the ON/OFF Switch to the 0 position
(ref. , 3fi g. 9, page 13). Disconnect the outdoor unit's
power supply.
2- Remove the front panel. Open the power control box.
Then turn the on the interface board,ON DIP SW1
3- Reconnect the power supply. Switch
the ON/OFF Switch to position 1.
(The green and red LEDs start fl ashing;
1s on / 1s off ). The outdoor unit begins cooling operation
about 3 minutes after being switched on.
4- The circulation pump starts.
5- maximum Close the liquid valve on the outdoor unit
30 secs after the outdoor unit starts.
6- Close the gas valve on the outdoor unit when the
pressure is below 0.02 relative bar read on the Manifold,
or 1-2 minutes after the liquid valve has been closed,
while the outdoor unit continues to operate.
7- Disconnect the power supply.
8- Recovery of the refrigerant is complete.
Notes :
- The pump down operation cannot be activated even
if DIP SW1 is set to ON while the heat pump is in
operation.
- Do not forget to switch back to after the DIP SW1 OFF
pump down operation has been completed.
- Select the heating mode.
- If the pump down operation fails, try the
operation again by turning the machine off and
opening the "liquid" and "gas" valves. Then after
2-3 minutes, restart the pump down operation.

Flushing the installation
Before connecting the hydraulic unit to the installation,
rinse out the heating system correctly to eliminate
any particles that may aff ect the appliance's correct
operation.
Do not use solvents or aromatic hydrocarbons (petrol,
paraffi n, etc.).
Flush the installation several times before
proceeding to the fi nal fi lling.
In the case of an old installation, provide a suffi ciently
large decanting pot with a drain on the return from the
heat pump and at the lowest point in the system in order
to collect and remove any impurities.
In some installations, the presence of diff erent
metals can cause corrosion problems;
the formation of metal particles and sludge can appear
in the hydraulic circuit. In this case, it is advisable to use
a corrosion inhibitor in the proportions indicated by the
manufacturer. You must also ensure that treated water
does not become corrosive (neutral pH: 7 <pH <9).
Flush the installation several times before
proceeding to the fi nal fi lling.
▼
Connections
The heating circulation pump is built into the hydraulic
unit.
Connect the central heating pipes to the hydraulic unit
correctly according to the direction of circulation.
The pipe between the hydraulic unit and the heat collector
must be at least one inch in diameter (26x34 mm).
Calculate the diameter of the pipes based on fl ow rates
and lengths of the hydraulic systems.
Tightening torque: 15 to 35 Nm.
Use union connectors to make it easier to remove the
hydraulic unit.
Try to use connection hoses to avoid transmitting noise
and vibrations to the building.
Connect the drains from the drain valve and the safety
valve to the main sewer system.
Verify that the expansion system is correctly connected.
Check the expansion vessel pressure (pre-infl ated to
1 bar) and the safety valve is calibrated.
The fl ow rate of the installation must be at least equal
to the minimum value mentioned in the table "General
characteristics", page 7. The installation of a regulator
(other than those included in our confi gurations) which
reduces or stops the fl ow through the hydraulic unit is
prohibited. fi g. 37 - Connections

Volume of the heating system
You must maintain the minimum installation water
volume. Install a buff er tank on the return from the
heating circuit in case the volume is lower than this
value. Where the system is fi tted with one or more
thermostatic valves, you must ensure that this minimum
water volume is able to circulate.

DHW circuit
Mandatory : On the cold water inlet, place a safety valve
calibrated to between 7 and 10 bar max. (depending on
local regulations) and connected to a drain pipe leading
to the sewer. The discharge pipe must be kept open
in the open air. The discharge pipe must be installed
in an environment kept frost-free and in a continuous
downward slope. Operate the safety valve according to
manufacturer's specifi cations. The domestic hot water
tank must be fed with cold water passing through a
safety valve. There must be no other valves between
the safety valve and the tank.
We recommend installing a thermostatic mixing valve
on the hot water outlet.

Filling and bleeding the installation
Check the pipe fi xings, tightness of the connectors and
the stability of the hydraulic unit.
Check the direction in which the water is circulating and
that all the valves are open.
Proceed to fi ll the installation.
Do not operate the circulation pump during fi lling.
Open all the drain valves in the installation and the
bleeder valve on the hydraulic unit ( ) to expel the air P
contained in the pipes.
Close the drain valves and add water until the pressure
in the hydraulic circuit reaches 1 bar.
Check that the hydraulic circuit has been bled correctly.
Check there are no leaks.
After the " Commissioning", page 46 stage, and
once the machine has started, bleed the hydraulic unit
again (2 litres of water).

Outside sensor
The outside sensor is required for correct operation of
the heat pump.
Please see the fi tting instructions on the sensor’s
packaging.
Place the sensor on the coldest side of the building,
generally the northern or north-western side.
It must not be exposed to morning sun.
It must be installed so as to be easily accessible but at
least 2.5m from the ground.
It is essential that it is not placed near any sources of
heat such as fl ues, upper parts of doors and windows,
near extractor vents, under balconies and eaves,
or anywhere which would insulate the sensor from
variations in the outdoor air temperature.
- Connect the outside sensor to connector X84 ( fi g. 45)
(terminals and ) on the heat pump control board.M B9
►
Room sensor (option)
The room sensor is optional.
Please see the fi tting instructions on the sensor’s
packaging.
The sensor must be installed in the living room area on
an unobstructed wall. It must be installed so as to be
easily accessible.
Avoid direct sources of heat (chimney, television,
cooking surfaces, sun) and draughty areas (ventilation,
door, etc.).
Draughts in buildings are often brought about by cold air
blowing through the electrical ducting. Lag the electrical
ducts if there is a cold draught behind the room sensor.
