" Installation and maintenance regulations

The appliance must be installed and maintained by an approved professional in accordance with current regulations and codes of practice.

" 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 suspension.

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 up a staircase). This operation must be conducted very carefully and the appliance must be immediately restored to the upright position.

" Containment of refrigeration circuits

All refrigeration circuits are sensitive to contamination from dust and moisture. If any such pollutants penetrate

the refrigeration circuit, they can a󰀨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 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.

Remember: Seal everything when tting in accordance

with industry standard practice for plumbing work:

- Use suitable seals (bre gasket, O-ring).

- Use Teon or hemp tape.

- Use sealing paste (synthetic depending on the case).

Use glycol/water mix if the minimum 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.

Remember: The presence at installation of a CB-type disconnection function, for preventing heating water being returned to the drinking water system, is required by articles 16.7 and 16.8 of the Local Plumbing Regulations.

" In some installations, the presence of di󰀨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.

- Please refer to the chapter "Treatment of domestic and heating water" in our price catalogue.

" You must also ensure that treated water does

not become corrosive.

" Electrical connections

• Before any maintenance operation, ensure that

the general power supply is switched o󰀨.

• Speci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 su󰀩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 (see tables page 37).

The electrical installation must be 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 xed installations,

particularly in a building. Tighten the cables using the cable glands to prevent the

feed wires from being accidentally disconnected. The earth connection and its continuity must be ensured.

• Connecting to screw terminals

" The use of ring, spade or blade terminals or

caps is prohibited.

- Always select wire that complies with current standards.

- Bare the end of the wire to around 25 mm.

- With round end pliers, form a loop with a diameter which matches the tightening screws on the terminal.

- Tighten the terminal screw rmly onto the loop created.

Insu󰀩cient tightening can cause overheating, leading to breakdown or even re.

1.1 Packing

• 1 package: Outdoor unit.

• 1 package: Hydraulic unit and outside temperature

sensor.

1.2 Unpacking and supplies

While the courier is still present, carefully check the general appearance of the appliances and check that the outdoor unit has not been laid in a horizontal position.

In the event of a dispute, send any relevant reservations to the carrier in writing within 48 hours and send a copy of the letter to Customer Services.

1.3 Denitions

- Split: The heat pump consists of two elements (an outdoor unit to be installed outdoors and a hydraulic unit to be installed inside the dwelling).

- Air/water: The surrounding air is the energy source. This energy is transmitted to the heating circuit water 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 pulling signicant

amounts of current at start-up.

- COP (Coe󰀩cient of Performance): This is the relationship between the energy transmitted to the heating circuit and consumed electrical energy.

Alféa Extensa Duo A.I. Heat Pump

1.6 Operating principle

The heat pump transmits the energy contained in the surrounding air into the dwelling to be heated and for production of domestic hot water.

The heat pump consists of four main parts, in which a refrigerant (R410A) circulates.

- In the evaporator (ref. 12, gure 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 -20°C outside temperature).

- In the compressor (ref. 9, gure 8, page 12): The vaporised refrigerant is pressurised and takes on even more calories.

- In the condenser (ref. 15, gure 9): The energy of the refrigerant is transmitted to the heating circuit. The refrigerant returns to its liquid state.

- In the expansion valve (ref. 8, gure 8, page 12):

The lique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 tted with an electrical backup or

boiler connection* which intervenes to provide additional heat during the coldest periods.

• Control functions

- The heating circuit's ow temperature is controlled by the temperature control.

- Depending on the heating 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,

management of the DHW circulation pump.

- Managing cooling*.

* Where the heat pump is 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 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 tari󰀨, the electrical backup is subject to the supplier’s power tari󰀨 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

2 Installation

2.1 Installation of refrigeration connections

" Bend the pipes into position and make holes

for them through the 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 (gure 19). Observe the maximum and minimum distances between

the hydraulic unit and the outdoor unit (gure 19, page

22); 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 5 m.

The appliance's warranty will be void if it is operated

with refrigeration connections less than 5 m long (tolerance +/- 10%).

If the refrigeration connections are exposed to weathering or UV radiation and the insulation is not resistant, protection must be provided.

2.2 Installation of the outdoor unit

2.2.1 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 (gure 13).

• 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 (gure 13).

• 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 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 drainage pipe can also be connected to the outdoor unit (gure 14).

• Nothing should obstruct the air circulation through the evaporator and out from the fan (gure 13).

• 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.).

- 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.

2.2.2 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 (gure 14).

- Fasten the outdoor unit by means of screws and rubber tightening or toothed lock washers to prevent them from coming loose.

" Warning

In areas with heavy snowfall, if the intake and outlet of the outdoor unit is blocked with snow, heating may

become di󰀩cult and a failure is likely to occur.

Construct a canopy or place the unit on a high stand

(local con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.

2.2.3 Condensate drain pipe

(see gure 14)

" The outdoor unit can generate a large volume of

water (called condensate).

If the use of a drain pipe is necessary:

- Install the condensate drain pan (optional / code 074008)

for Alféa Extensa Duo A.I. models 5, 6 and 8 only.

- Use the elbow provided (C) 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.

Allow for the condensate to 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.

2.3 Installation of the hydraulic unit

2.3.1 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 to allow access to the various components, we recommend that you provide su󰀩cient space all around the hydraulic unit (gure 15).

• In accordance with EN 378-1 -2017 standard (Refrigerating systems and heat pumps - Safety and

environmental requirements), the system's hydraulic

unit and all refrigeration connections passing through inhabited areas must comply with the minimum room volume requirements shown hereafter.

The minimum volume of a room (in m3) is calculated

using the formula: "uid ll load" (in kg) / 0.39.

Alternatively, you must ensure that

- the location has natural ventilation through another room where the combined volume of the two rooms

is greater than "liquid ll load" (in kg) / 0.39 kg/m3.

The opening between the two rooms must have a door clearance of at least 1 cm.

- or that the location is mechanically ventilated.

• Be careful not to bring ammable gas near the heat pump during installation, in particular when brazing is required.

The appliances are not reproof and should not

therefore be installed in an explosive environment.

- 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 nal connection, take care to put

the caps back in position to avoid any pollution of the refrigeration circuit (sealing with adhesive is prohibited).

" This appliance uses refrigerant R410A.

Comply with the legislation on handling of refrigerants.

3.1 Rules and precautions

" Connections must be made on the same day the

installation is lled with gas (see para. page 24).

• Minimum tools required

- Set of pressure gauges (Manifold) with hoses

exclusively designed for HFCs (Hydrouorocarbons).

- Vacuum gauge with isolation valves.

- Vacuum pump specically for HFCs (using a standard

vacuum pump is allowed if, and only if, it is tted with

a non-return valve on the suction side).

- Flaring tool, Pipe-cutter, Deburring tool, Spanners.

- Certied refrigerant gas leak detector (sensitivity 5g/year).

" Using tools that have been in contact with

HCFCs (R22 for example) or CFCs is prohibited.

" The manufacturer declines any liability with

regard to the warranty if the above instructions are not observed.

• Flared connections

" Lubricating with mineral oil (for R12, R22) is prohibited.

- Lubricate only with polyolester oil (POE). If POE is not

available, t without lubrication.

Coat the ared surface with POE

refrigeration oil.

Do not use mineral oil.

• Brazing the refrigeration circuit (if necessary)

- Silver brazing (40% minimum recommended).

- Brazing only with dry nitrogen internal ux.

• Other remarks

- After each maintenance operation on the refrigeration

circuit and before nal connection, take care to put

the caps back in position to avoid any pollution of the refrigeration circuit.

- To eliminate any lings getting into the pipes, use dry nitrogen to avoid introducing any humidity that may

adversely a󰀨ect the appliance's operation. In general,

take every precaution to avoid humidity penetrating into the appliance.

- Proceed with thermal insulation of 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 refrigerant 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 reaches 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, use insulating sleeves whose thermal conductivity will be less than or equal to 0.045 W/mK if the temperature is equal to 20°C. The insulation must be impermeable in order to withstand the passage of vapour during the defrosting cycles (glass wool is prohibited).

3.2 Shaping the refrigeration pipes

3.2.1 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.

" Warning!

• Remove the insulation material from the section of pipe to be bent.

• Do not bend copper to an angle greater than 90°.

• Never bend pipes more than 3 times in the same place otherwise traces of fracturing may appear (hardening of the metal).

If additional lling is required, do it before

lling the hydraulic unit with gas. Refer to

paragraph "Additional lling", page 27.

- Remove the access plugs (A) 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.

- Ret the 2 original caps (be sure they are clean) and tighten them to the recommended tightening torque indicated in the table gure 20, page 23. 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 ushing is strictly forbidden.

3.4.4 Final sealing test

The sealing test must be carried out with a certi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 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 Manifold) so as not to contaminate the recovered gas with air or moisture.

- Redo the connection,

- Restart the commissioning procedure.

- Disconnect the vacuum pump (yellow hose) and connect a bottle of R410A in its place in the uid

extraction position.

- Open the bottle’s valve.

- Bleed the yellow hose by loosening it slightly on the Manifold side.

- Place the bottle on scales with a minimum accuracy of

10g. Note the weight.

- Carefully open the blue valve slightly and check the value shown on the scales.

- As soon as the value displayed has dropped by the

value for the calculated additional ll amount, close the

bottle and disconnect it.

- Quickly disconnect the hose connected to the appliance.

- Proceed to ll the hydraulic unit with gas.

4.1 Connecting the hydraulic unit to the heating circuit

4.1.1 Flushing the installation

Before connecting the hydraulic unit to the installation, rinse out the heating system correctly to eliminate

any particles that may a󰀨ect the appliance's correct

operation.

Do not use solvents or aromatic hydrocarbons (petrol, para󰀩n, etc.).

In the case of an old installation, provide a su󰀩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 any impurities.

Add an alkaline product and a dispersant to the water. Flush the installation several times before proceeding

to the nal lling.

4.1.2 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 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-inated to 1

bar) and the safety valve is calibrated.

The ow rate of the installation must be at least equal to the minimum value mentioned in the specications table

(section 1.4, page 7). The installation of a regulator

(other than those included in our congurations) which reduces or stops the ow through the hydraulic unit is

prohibited.

7.6 Temperature control

The heat pump's operation is subject to the temperature

control. The heating circuit water temperature setpoint is

adjusted according to the outdoor temperature.

If there are thermostatic valves on the installation, these must be fully open or set higher than the normal temperature setpoint.

7.6.1 Setting

During the installation, the temperature control must be congured to suit the radiators and level of insulation of

the dwelling. The temperature control graphs (gure 42) refer to a

room temperature setpoint of 20°C.

The temperature control's gradient determines the

impact of variations in the outdoor temperature on

variations in the heating ow temperature.

The steeper the gradient, the more likely a slight reduction in the outdoor temperature will cause a

signicant increase in the water ow temperature in the

heating circuit.

The temperature control o󰀨-set modies the ow

temperature of all graphs, without modifying the gradient (gure 43).

Corrective actions to take in the case of discomfort are listed in the table (gure 44).

12.3 Checking the outdoor unit

- Remove any dust from the exchanger, if necessary, while making sure not to damage the blades.

- Straighten the blades using a comb.

- Check that there is nothing blocking the air ow.

- Check the fan.

- Verify that condensate drain is not obstructed.

• Checking the refrigeration circuit :

If the amount of refrigerant in the system exceeds 2kg (models > 10kW), the refrigeration circuit must be checked annually by an approved engineer (they must

have a certicate of competence for the handling of

refrigerants).

- Check there are no leaks (connections, valves…).

12.4 Checking the electrical circuit

- Check the connections and re-tighten if necessary.

- Check the state of the cables and plates.

" Before any maintenance operation, make sure

that the general power supply is switched o󰀨.

12.1 Checking the hydraulic circuit

" If frequent rells are required it is absolutely

essential that you check for any leaks. If relling

and a pressure reset are necessary, check what

type of uid was used initially.

Recommended lling pressure: between 1 and 2 bar (the exact lling pressure is determined by the water

pressure in the installation).

Every year,

- Check the expansion circuit pressure (pre-ination to 1 bar) and the correct operation of the safety valve.

- Check the safety valve on the cold water supply inlet.

Make it operate as advised by the manufacturer.

- Check the shut-o󰀨.

- Check the correct operation of the distribution valve.

12.2 Maintenance of the DHW tank

Maintenance on the tank must be carried out annually

(frequency may vary according to water hardness).

12.2.1 Emptying the hot water tank

- Remove the front panel from the HP.

- Close the cold water inlet into the tank.

- Open a hot water tap and open the water tank drain valve (ref. 1).

12.2.2 Descaling

- Empty the water tank.

- Remove the cowl from the electrical backup (ref. 2).

- Disconnect the electrical backup.

- Disconnect the ACI.

- Remove the electrical backup (ref. 3).

- Descale the exchanger to maintain performance.

- Remove any scale deposits that may have accumulated in the tank. It is best to leave any scale sticking to the sides of the tank: this forms a protective layer.

- Gently remove any scale deposits on the thermowell.

Do not use any metal objects or chemical or abrasive

products.

- Replace the electrical backup's gasket (ref. 4) each time it is dismantled.

- Reinstall the electrical backup and tighten alternate nuts in rotation.

- Reconnect the electrical backup.

- Reconnect the ACI.

- Replace the cowl on the electrical backup.

15 ErP performance gures

15.1 Denition of ErP

The term "ErP" includes two directives that are part of the European program for reducing greenhouse gases:

- The Ecodesign Directive establishes e󰀩ciency thresholds and prohibits the marketing of products whose e󰀩ciency is below these thresholds.

- The Energy Labelling Directive requires an energy performance label for products, in order to encourage customers to buy products that consume less energy.
