1 Description of the unit
1.1 Package
• 1 package: outdoor unit.
• 1 package: hydraulic unit and outdoor sensor.
1.2 Denitions
- Split: The heat pump consists of two elements (an
outdoor unit for outdoor and a hydraulic unit for inside
the dwelling).
- Air/water: The surrounding air is the energy source.
This energy is transmitted to the water in the heating
circuit by the heat pump.
- Inverter: the fan and compressor speeds are
modulated according to the heating requirements.
This technology enables you to save on energy and
operate on a single-phase power supply, whatever the
heat pump's output, by avoiding heavy intensities on
start-up.
- COP (coefcient of performance): this is the relationship
between the energy transmitted to the heating circuit
and electrical energy consumed.

1.5 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 uid (R410A) circulates.
- In the evaporator (reference 13, gure 7, page 9) :
The energy is taken from the surrounding air and is
transmitted to the refrigerant. Because it has a low
boiling point, it changes from the liquid state to the
vapour state, even in cold weather (down to -15 °C
outdoor temperature).
- In the compressor (reference 10, gure 7, page 9) :
The vaporised refrigerant brought to high pressure
and takes on more calories.
- In the condenser (reference 14, gure 8, page 10) : The
energy in the refrigerant is transmitted to the heating
circuit. The refrigerant returns to liquid state.
- In the expansion valve (reference 9, gure 7, page 9) :
The liqueed refrigerant is brought back to low pressure
and returns to its initial temperature and pressure.
The heat pump is equipped with a controller, which
controls the room temperature based on the outdoor
temperature measurement and governed by the
temperature control. The room thermostat (option)
provides a corrective action for the temperature control.
The heat pump is equipped with an electrical back-up
system, which is designed to provide additional heat
during the coldest periods.

• Domestic hot water (DHW) operating principle
Two domestic hot water (DHW) temperatures can be
parametered: nominal temperature (see user interface
reference 2, gure 34, page 30) and reduced temperature
(line 65 to 40 °C).
The default heat pump program is set for nominal
temperature from 0.00 to 5.00h and for reduced
temperature for the rest of the day, this optimizes
electrical consumption while ensuring comfortable
availability of hot water.
Setting for reduced temperature can be useful to prevent
the DHW from switching on too often and for too long
during the day.
The production of domestic hot water (DHW) is triggered
when the temperature in the tank falls 7°C below the set
temperature.
The heat pump produces the domestic hot water,
which is then additively heated, if required, by electrical
back-up heating inside the tank.
To ensure a DHW setting over 45°C, the electrical
back-up heating or the boiler must be left on.
Depending on how the parameter 83 is set, nominal
temperature can be reached 24h/day or only at night or
depending on the heat pump programme.
The production of DHW takes priority over heating;
nevertheless the production of DHW is controlled by
cycles that control the times assigned to the heating
and the production of DHW in the event of simultaneous
demand.
A function to switch from "reduced" to "nominal"
is provided on the front of the user interface
(see reference 5, gure 34, page 30).
Anti-legionella cycles can be programmed.
• Fan convectors with integrated control system
Do not use a room sensor in the area.

2.2.3 Accessories provided
Accessories provided with the outdoor unit (gure 10).
Accessories provided with the hydraulic unit (gure 11).
2.3 Installation position
The choice of the position for installation is particularly
important insofar as any later movement is a delicate
operation requiring the intervention of a qualied person.
Choose the site of the outdoor unit and the hydraulic
unit after discussion with the customer.
Observe the maximum and minimum distances between
the hydraulic unit and the outdoor unit (gure 13); the
guarantee of the performances and the system's service
life depend on this.
2.4 Installation of the outdoor unit
2.4.1 Installation precautions
"The outdoor unit must only be installed outdoor
(outdoors). If a shelter is required, it must have
broad openings on the 4 walls and observe the
installation clearances (gure 12).
• Choose a site that is preferably sunny and sheltered
from strong cold predominant winds (mistral,
tramontana, etc…).
• The unit must be easily accessible for future installation
and maintenance work (gure 12, page 13).
• Ensure that it is possible to make the connections to
the hydraulic unit easily.
• The outdoor unit is able to withstand bad weather but
avoid installing in a position where it is likely to be
exposed to signicant dirt or owing water (under a
defective gutter for example).
• Water may drain away from the outdoor unit when it
is operating. Do not install the appliance on a paved
terrace; choose a well-drained place (e.g. gravel
or sand). If the installation is in an area where the
temperature can be lower than 0°C for a long period,
check that the presence of ice does not present any
danger. A drainage pipe can also be connected to the
outdoor unit (see page 14).

2.4.2 Outdoor unit positioning
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 (gure 14).
- Fasten the outdoor unit by means of screws and
rubber tightening or toothed lock washers to avoid
their coming loose.
2.4.3 Condensate drain hose
(see gure 14).
If the use of a discharge pipe is imperative:
- Use the elbow provided (C) to connect a 16mm
diameter hose for draining away the condensate.
- Use the stopper or stoppers provided (B) to block the
opening of the condensate tank.
Allow for the condensate to ow away under the force of
gravity (waste water, rain water, gravel bed).
"If the installation is made in an area where
the temperature can be lower than 0°C for
a long period, provide the drain pipe with a
trace resistance to avoid it icing up. The trace
resistance must heat not only the pipe but
also the bottom of the appliance's condensate
collection tank.

2.6 Refrigeration connections
"This appliance uses refrigerant R410A.
Comply with the legislation for handling refrigerants.
2.6.1 Rules and precautions
• 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.
• Tools
- Set of manometers with hoses exclusively reserved
for HFCs.
- Vacuum pump specially for HFCs.
- Provision on using tools that have been in contact with
HCFCs (R22 for example) or CFCs.
- Use of a traditional vacuum pump is authorized if, and
only if, it is tted with a non-return valve on the suction
side.
The manufacturer declines any liability with regard to the
guarantee if the above instructions are not observed.
• Flared connections
"Lubrication with mineral oil (for R12, R22) is
forbidden.
- Only lubricate with polyolester refrigeration oil (POE).
If POE is not available, t without lubrication.
2.6.2 Refrigeration connections
The outdoor unit must be connected to the hydraulic
unit with copper pipes and connections (refrigeration
quality), insulated separately.
Comply with the pipe diameters and the permitted pipe
lengths (gure 13).
The minimum length of the refrigeration connections
is 5 m for correct operation.
The appliance will be excluded from guarantee if it is
used with refrigeration connections less than 5 m long.
Manipulate the pipes and take them through walls with
protective plugs in place.
2.6.3 Accessing the hydraulic module’s
refrigerant connections
- Remove the front panel (2 screws A, gure 16).
- Remove the left-hand panel (2 screws B, gure 17).
Coat the ared surface with
POE refrigeration oil.
Do not use mineral oil.
• Brazing on the refrigeration circuit (if necessary)
- Silver brazing (40% minimum recommended).
- Brazing only under dry nitrogen internal ux.
• To eliminate any lings in the pipes, use dry nitrogen
to avoid introducing any humidity that may adversely
affect the appliances operation. In general, take every
precaution to avoid humidity penetrating into the
appliance.
• Proceed to insulate the gas and liquid pipes to avoid
any condensation. Use pipe insulators resistant to
temperatures over 90°C. In addition if the humidity
level in areas where the refrigeration pipes are
installed is expected to exceed 70%, protect the pipes
with pipe insulators. Use an insulating material thicker
than 15mm if the humidity level is 70~80%, and an
insulating material thicker than 20mm if the humidity
exceeds 80%. If the recommended thicknesses are
not observed under the conditions described above,
condensation will form on the surface of the insulation
material. Lastly, take care to use pipe insulators
whose thermal conductivity is 0.045 W/mK or less
when the temperature is 20°C. The insulation must be
impermeable to resist the passage of steam during the
defrosting cycles (breglass wool is prohibited).

2.6.5 Shaping the refrigeration pipes
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.
"Warning !
• Remove the insulation material locally to bend the
pipes.
• Do not bend the copper to any angle over 90°.
• Never bend pipes more than 3 times in the same
position otherwise traces of fracturing may appear
(from strain-hardening the metal).
2.6.6 Connecting the ared connections
"Take particular care positioning the tube
opposite its connector so as not to risk damaging
the threads. A carefully aligned connector can
be tted easily by hand without much force
being required.
"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.
- Depending on the case, connect an adapter (reducer)
1/4''- 3/8'' or 1/2''- 5/8' (see gure 18).
- Remove the plugs from the pipes and the refrigeration
connections.
- Present the pipe to the ared connector and screw the
nut by hand while holding the connector with a wrench

2.7 Filling the installation with gas
"This operation is reserved for installers familiar
with the legislation for handling refrigerants.
"Creating a vacuum with a vacuum pump is
essential.
"Never use equipment used beforehand with any
refrigerant other than a HFC.
2.7.1 Creating a vacuum and
lling the refrigeration connections with gas
• First seal test
- Remove the protective plugs (B) from the charging
hole (Schrader) in the gas valve (large diameter).
- Connect the hose to the manifold,
- Connect the bottle of nitrogen to the manifold.
- Pressurize the refrigerant circuit to 10 bar with nitrogen.
- Leave the circuit under pressure for half a day.
- Check that the pressure has not fallen.
- Look for and repair any leaks, and then recommence
the test.
- Once the pressure has remained steady for a few
hours, empty the nitrogen.
• Creating a vacuum and lling the refrigeration
connections with gas
- Connect the vacuum pump to the manifold.
- Create a vacuum until the residual pressure in the
circuit falls below 0,01 bar.
- Let the pump continue to operate for another 30
minutes after reaching the vacuum.
- Close the blue valve on the set of manometers and
then stop the vacuum pump without disconnecting
any of the hoses in place.
- Leave for at least half a day.
If after this time the pressure has risen, there
is a leak. Find and repair the leak and then
recommence vacuum testing.
When the pressure remains steady for a few
hours after stopping the vacuum pump, the circuit
can be considered airtight.
- Remove the access plugs (A) from the valve controls.
- First of all fully open the small valve and then the
large one using a hex key (counterclockwise direction)
without forcing excessively against the stop.
- Remove the blue hose rapidly.
- Ret the 2 plugs and tighten them to the recommended
tightening torque gure 18 page 17.
The outdoor unit does not contain any additional
refrigerant, enabling the installation to be purged.
Flushing is strictly forbidden.
2.7.2 Sealing test
Once the refrigeration circuit has been gassed as
described above, check that all the refrigeration
connectors are gas-tight:
6 connectors for models Evolution 5 and Evolution 6, 5
connectors for model Evolution 8 and 4 connectors for
models Evolution 10, Evolution 13 and Evolution 16.
The sealing test must be performed with an approved
gas detector. If the arings have been made correctly,
there should be no leaks.
"If there is a leak:
- Bring the gas into the outdoor unit (pump down),
- Make the connection again,
- Repeat the commissioning procedure.

2.8 Connecting the heating
circuit hydraulically
2.8.1 General
The connection must comply with good trade practice
according to local building regulations.
The heating circulating pump is built into the
hydraulic unit.
Connect the central heating pipes to the appliance,
complying with the direction of circulation.
The pipe between the heat pump and the heat collector
must be at least one inch in diameter (26x34 mm).
Calculate the diameter of the pipes according to the
ow rates and the lengths of the hydraulic systems.
Tightening torque : 15 to 35 Nm.
Use union connectors to facilitate removing the
hydraulic unit.
Preferentially 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.
Reminder: Seal everything when tting in accordance
with prevailing trade practice for plumbing work:
- Use suitable seals (bre seals, o-rings).
- Use Teon tape or hemp.
- Use sealing paste (synthetic depending on the case).
The use of glycol is not necessary.
If you are using a glycol/water mix, provide for an annual
check on the quantity of glycol. Use monopropylene
glycol only. Never use monoethylene glycol.
In certain installations, the presence of different metals
can cause corrosion problems; the formation of metal
particles and sludge in the hydraulic circuit is then seen.
In this case, it is advisable to use a corrosion inhibitor in
the proportions indicated by its manufacturer.
It is also necessary to ensure that the treated water
does not become aggressive.
2.8.2 Rinsing out the installation
Before connecting the hydraulic unit to the installation,
rinse out the heating system correctly to eliminate
any particles that may affect the appliance's correct
operation.
Do not use solvents or aromatic hydrocarbons (petrol,
parafn, etc.).
In the case of an old installation, provide a sufciently
large decanting pot with a drain on the return from the
boiler and at the lowest point in the system in order to
collect and remove the impurities.
Add an alkaline product to the water and a dispersant.
Rinse the installation several times before lling it
denitively.
2.8.3 Filling and purging the installation
Check the pipe xings, the tightness of the connectors
and the stability of the appliance.
Check the direction in which the water is circulating and
that all the valves open.
Proceed to ll the installation.
Do not operate the circulating pump while lling. Open
all the drain valves in the installation and the bleeder
valve for the hydraulic unit to remove the air contained
in the conduits.
Close the drain and bleeder valves and add water until
the pressure in the hydraulic circuit reaches 1,5 bars.
Check that the hydraulic circuit has been purged
correctly.
Check that there are no leaks and that the circulating
pumps are not seized (if need be, release them).
After the "Start-up" stage (see page 28), once the
machine has started, purge the hydraulic unit again.
2.8.4 Connecting a fan-convectors circuit
It must be installed on this circuit a buffer tank
(minimum capacity: 50 liters).
