1.3 Scope
This heat pump permits:
- heating in winter,
- production of domestic hot water,
- control of two heating circuits*,
- heating of the swimming pool*.
*: These options require the use of additional kits
(see § "Optional equipment").
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
(heat pump air/water and built in fuel boiler).

1.7 Operating principle
The heat pump transmits the energy in the outdoor air
to the home to be heated.
The heat pump is formed of four main elements inside
which a refrigerating uid circulates (R410A).
- In the evaporator (ref. 13, gure 8, page 9):
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 (rep. 10 or 16, gure 8, page 9):
The vaporised refrigerating uid is pressurised and
thus carries more calories.
- In the condenser (ref. 1, gure 9, page 10): The energy
of the refrigerating uid is transmitted to the heating
circuit. The refrigerating uid returns to its liquid state.
- In the pressure regulator (ref. 9or 15, gure 8, page 9):
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 with a burner with All
or Nothing operation, controlled by the regulator:
- to provide additional heating during the colder periods,
- to provide support for the domestic requirements (DHW)
or
- to provide a relay during "Peak rate" days (load
shedding or EJP function, see page 30).
Priority is given to the operation of the heat pump.
When the heat pump is not sufcient for the heating, the
burner automatically takes over.
• 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.
- Domestic hot water: Timer heating programme,
management of operation of the DHW circulation
pump.
- Ambient sensor*: The ambient sensor provides a
corrective action to the water logic.
- Management of a 2nd heating circuit*.
- Management of the heating of the swimming pool*.
*When the heat pump is equipped with options and associated kits.
• Protection functions
- Anti-legionella cycle for the domestic hot water.
- A pressure switch monitors the hydraulic pressure.
If the pressure is below 0.5 bar, an error message is
displayed (369) and the heat pump is stopped.

• Operating principle of the domestic hot water
(DHW)
Two domestic hot water (DHW) temperatures can
be set: comfort temperature (line 1610 at 65°C) and
reduced temperature (line 1612 at 40°C).
The default DHW programme (line 560, 561, 562, 563
and 564) is set for a comfort temperature from 0h00
to 5h00 and from 15h00 to 18h00 and a reduced
temperature for the rest of the day.
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 then completed if required by the burner. To
ensure there is an DHW value higher than 45°C, the
burner must be operated.
Depending on the setting of the parameter (1620), the
comfort temperature may be reached either
- 24 h/day,
- in line with the timer programme of the heating
circuit,
- in line with the DHW timer programme,
- during the off peak periods,
- during the off peak periods and in line with the
DHW timer programme.
The DHW production has priority over the heating,
nevertheless the production of DHW is managed by
cycles that regulate the time allocated to heating and
to the production of DHW in case of simultaneous
demands.
A switching function of "reduced" to "comfort" is
available on the front panel of the user interface
(see ref. 1, gure 50, page 36).
Anti-legionella cycles may be programmed
(lines 1640 to 1647).
• Fan coil units with integrated regulation
Do not use an ambient sensor in the zone concerned.

2.1 Statutory conditions
for installation and servicing
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 Use of new fuels
This boiler and its burner are compatibles with the new
domestic fuel containing FAME (fatty acid methyl
ester) on the condition that the rules are respected for
the use and storage of this fuel (see user instructions,
§ Rules for use and storage of domestic fuel containing
FAME).
2.3 Unpacking and reserves
2.3.1 Receipt
When the courier is present, carefully check the general
appearance of the appliances, check that the outdoor
unit has not been laid at.
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.
2.3.2 Handling
The outdoor unit must not be in horizontal position
during transport.
Transport in horizontal position creates a risk of damage
to the inner tubes and the compressor suspensions.
Damage caused by transport in horizontal position are
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.
2.3.3 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.
2.3.4 Accessories supplied
Accessories provided with the outdoor unit (gure 12).
Accessories provided with the hydraulic unit (gure 13).
2.4 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 23, page 20), as the
performances and life of the system depend on this.

2.5 Installing the outdoor unit
2.5.1 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 (gure 15 and
gure 16).
• Prefer a sunny location, sheltered from strong and
cold dominant winds.
• The appliance must be completely accessible for
subsequent installation and maintenance work
(gure 15 and gure 16).
• Ensure that the connections can be made easily with
the hydraulic module.
• The outdoor unit can be exposed to the weather,
however avoid installing it in places where it will
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, prefer
a place that has drainage (bed of sand or gravel).
if it is installed in a region where the temperature
may drop below 0°C for a long period, check that the
presence of ice does not cause any danger. It is also
possible to connect a pipe to evacuate to the outdoor
unit (see gure 14).
• No obstacles must obstruct the circulation of air
through the evaporator and the fan outlet.
• Keep the outdoor unit away from sources of heat or
inammable products.
• 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 vibrations to the accommodation
(anti-vibration pads are available in option).
• The wall bracket can not be used in conditions likely to
transmit vibrations, ground position is preferred.
2.5.2 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.
-Attach the outdoor unit using screw and spring or split
washers to ensure they do not come loose.

2.6 Installing the hydraulic module
2.6.1 Requirements of installation space
The room where the appliance operates must respect
the regulations in force.
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 of at least
50 cm2 located in the lower part and a used air outlet
(B) with a free non-blockable cross section of at least
100 cm2 positioned in the upper part and opening
directly outdoors (see gure 17).
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.
"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.
This equipment may not be installed in a bathroom or a
shower room.
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 anti-
explosion 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).
2.6.2 Evacuation pipe
(see gure 18)
The evacuation pipe must comply with the regulations
in force.
The evacuation pipe must have suitable dimensions.
Minimum obligatory cross section = 2.5 dm2 for a
chimney of height between 5 and 20 m, or in bushels of
16 cm or Ø 18 cm.
The pipe must only be connected to a single appliance.
The pipe must be waterproof.
The pipe must be correctly thermally insulated in order
to avoid any problems of condensation; otherwise the
pipe must have a tube tted with a system for collecting
the condensates.
Use a good quality watertight tube that is compatible
with the fuel used, possibly with a system for collecting
the condensates.

2.6.3 Connection pipe
The evacuation pipe must comply with the regulations
in force.
The cross section of the connection pipe must not be
smaller than the outlet nozzle of the appliance.
The connection pipe must be removable.
It is strongly recommended to t a ue regulator to the
pipe when the low pressure of the chimney is greater
than 30 Pa.
The ue gas case is reversible (2 screws) and the
smoke outlet axis may be offset with respect to the axis
of the boiler to the right or to the left.
The evacuation nozzle is to be connected to the pipe so
that there are no leaks.
2.7 Refrigerating connections
"This appliance uses the refrigerating uid
R410A.
Respect the legislation for handling refrigerating uids.
2.7.1 Rules and precautions
• After each operation on the refrigerating circuit, and
before the nal connection, ensure that the plugs are
tted so as to avoid any pollution of the refrigerating
circuit.
• Minimum necessary tools
- Set of manometers (Manifold) with hoses exclusively
reserved for HFCs (Hydrouorocarbons).
- Vacuum gauge whith isolation valves.
- Vacuum pump specially for HFCs (use of a traditional
vacuum pump is authorized if, and only if, it is tted
with a non-return valve on the suction side).
-Flaring tool.
- Pipe-cutter.
- Deburring tool.
- Wrenches.
-Refrigerant gas leak detector certied (sensitivity 5g/year).
"Provision on using tools that have been in
contact with HCFCs (R22 for example) or CFCs.
"The manufacturer declines any liability with
regard to the guarantee if the above instructions
are not observed.
• Tube expanders (ared connectors)
"Lubrication with mineral oil
(for R12, R22) is not allowed.
- Only lubricate with polyolester refrigerating oil (POE).
If POE oil is not available, t without oil.
Coat the ared surface
with refrigerating oil POE.
Do not use mineral oil.
• Brazing on the refrigerating circuit
(if required)
- Silver brazing (40% minimum recommended).
- Brazing with a dry Nitrogen stream only.
• To eliminate the swarf from the pipes, use dry
Nitrogen to avoid introducing humidity that can harm
the operation of the appliance. In general, take all
precautions to avoid humidity penetrating into the
appliance.
• Thermally insulate the gas and liquid pipe to avoid
all condensation. Use insulating sleeves that resist
temperatures of over 90°C. In addition, if the level
of humidity where the refrigerating pipes risks
exceeding 70%, protect them with insulating sleeves.
Use a 15 mm thicker sleeve if the humidity reaches
80%, and a 20 mm thicker sleeve if the humidity
exceeds 80%. If the recommended thicknesses
are not respected in the conditions described
above, condensation will form on the surface of the
insulation. Finally, ensure that insulating sleeves are
used that have a thermal conductivity equal to 0.045
W/mK or lower when the temperature is equal to
20°C. The insulation must be impermeable to resist
the steam passing during the defrosting cycles (glass
wool is prohibited).

2.7.2 Refrigerating connections
The connection between the outdoor unit and the
hydraulic module using only copper connections
(refrigerating grade), must be insulated separately.
Respect the diameters of pipe and the authorised
lengths (gure 23, page 20).
Handle the pipes and pass them through the walls with
the protection plugs in place.
If the distance between the outdoor unit and the
hydraulic module exceeds the maximum pipe lengths
shown in the table, then an additional charge of R410A
is required.
The quantity of R410A added must be suited to the
length of the refrigerating circuit in order to maintain
the performances of the heat pump without however
damaging the compressor (gure 25, page 22).
2.7.3 Flaring
- Cut the tube with a tube cutter to the required length
without deforming it.
- Carefully deburr while holding the tube downwards to
avoid introducing swarf into the tube.
- Remove the are nut from the connector on the valve
to be connected and t the tube into the nut.
- Flare it leaving the tube protruding fro the expandable
aring tool.
- After aring, check the state of the journal (L).
It must not be scratched or signs of splitting. Also
check the dimension (B).
2.7.4 Forming the refrigerating tubes
The refrigerating tubes must only be formed using a
bending machine or a bending spring in order to avoid
any risks of crushing or splitting.
"Warning!
• Remove the insulation locally to bend the tubes.
• Do not bend the copper to an angle of more than 90°.
• Do not bend the tubes more than 3 times at the same
position otherwise this can cause the pipe to split
(hardening of the metal).
2.7.5 Connecting the are connections
"The small tube must always be connected
before the large one.
"Pay special attention to the position of the tube
aligned with its connector to avoid damaging
the thread. A correctly aligned connector can be
tted easily by hand without much force being
required.
"The refrigerating circuit is very sensitive to dust
and humidity, check that the zone around the
connection is dry and clean before removing the
plugs that protect the refrigerating connectors.
- Remove the plugs from the pipes and refrigerating
connections.
- Place the tube in front of the are connector and
screw on the nut by hand, holding the connector with a
spanner, until contact is made.
- Respect the tightening torques dened.
