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 singlephase 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 consumed electrical energy.

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 (ref. 13, gure 6, 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 -25 °C outdoor temperature).

- In the compressor (ref. 10, gure 6, page 9) : The vaporised refrigerant brought to high pressure and takes on more calories.

- In the condenser (ref. 15, gure 7) : The energy in the refrigerant is transmitted to the heating circuit. The refrigerant returns to liquid state.

- In the expansion valve (ref. 9, gure 6, 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.

• Domestic hot water (DHW) operating principle

Two domestic hot water (DHW) temperatures can be parametered: nominal temperature (line 1610 to 55 °C) and reduced temperature (line 1612 to 40 °C).

The default heat pump program (line 560, 561 and 562) is set for nominal temperature from 0:00 to 5:00 and from 14:30 to 17:00 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 (setting from line 5024) below the set temperature.

The heat pump produces the domestic hot water, which is then additively heated, if required, by electrical backup 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 (1620) is set, nominal temperature can be reached 24h/day or only at night or depending on the heat pump program.

gure 8 - Heat pump operating principle

If the contract concluded with the energy provider includes a subscription to day/night tariff, the electrical backup is subordinate to the supplier’s power tariff and the comfort temperature may only be reached at night.

If no particular contract is concluded, 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 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 ref. 1, gure 45, page 42).

Anti-legionella cycles can be programmed.

2.1 Regulation installation and maintenance conditions

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 reservations

2.2.1 Receipt

Carefully check, in the carrier's presence, the general appearance of the appliances and check that the outdoor unit is not laid on its side or back.

In the case of any dispute, state any appropriate reservations to the carrier in writing within 48 hours and send a copy of this letter to the After-Sales service.

2.2.2 Handling

The outdoor unit should not be laid on its side or back during transport.

If not kept upright during transport, the appliance could be damaged through displacement of the refrigerant and deformation of the compressor suspension.

Any damage caused by transportation of the unit lying down is not covered by the warranty.

If necessary the outdoor unit may be tilted only during manual handling (to go through a door or use a staircase). This operation must be conducted very carefully and the appliance must be immediately restored to upright position.

2.2.3 Containment of refrigerant circuits

All refrigerant circuits fear contamination from dust and moisture. If such pollutants introduced into refrigerant 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 refrigerant circuit caps mounted on hydraulic unit and outdoor unit are properly seated and locked (impossible to loosen bare hands). If 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.

crossing (slab or wall) with protective caps in place or after brazing.

" Keep the protective caps or ends soldered to

the commissioning of the appliance.

The outdoor unit must be connected to the hydraulic unit only with new copper pipes and connections (Refrigerant quality), insulated separately.

Respect the pipes diameters (gure 20, page 19). Observe the maximum and minimum distances

between the hydraulic unit and the outdoor unit (gure 20, page 19); the guarantee of the performances and the system's service life depend on this.

The minimum length of the refrigerant connections is 5 m for correct operation.

The appliance will be excluded from guarantee if it is used with refrigerant connections less than 5 m long (tolerance +/- 10%).

If the refrigerant connections are exposed to weathering or UV- and the insulation is not strong, it is necessary to provide protection.

2.4.1 Installation precautions

The outdoor unit must 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 the location of the appliance after discussion with the client.

• 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).

• 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 (gure 13).

• Nothing should obstruct the air circulation through the evaporator and from the fan (gure 12).

• Keep the outdoor unit away from heat sources and inammable products.

• Make sure the appliance not disturb the surrounding area or users (noise level, draught generated, low temperature of the air being blown out, with the risk of freezing plants in its path).

• The surface on which the appliance is installed must:

- be permeable (soil, gravel, etc),

- support its weight easily,

- provide a solid xing and

- not transmit any vibration to the dwelling.

(Anti-vibratory blocks are available as an option).

• The wall bracket can not be used in conditions likely to transmit vibrations, ground position is preferred.

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 13).

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

" Warning

In the area with heavy snowfall, if the intake and outlet of outdoor unit is blocked with snow, it might become difcult to get warm and it is likely to cause of the breakdown.

Please construct a canopy and a pedestral or place the unit on high stand (local congured).

- Set the unit on a strong stand, such as one made of concrete blocks to minimize shock and vibration.

- Do not set the unit directly on the ground because it will cause trouble.

2.4.3 Condensate drain hose

(see gure 13). 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 drain pan.

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 the outdoor unit.

2.5 Installing the hydraulic unit

2.5.1 Installation precautions

• Choose the location of the appliance after discussion with the client.

• The room in which the appliance operates must comply with the prevailing regulations.

• To facilitate maintenance and to allow access to the various components, we recommend that you provide sufcient space all around the hydraulic unit (gure 14).

• According to standard EN 378-1 (safety requirements and HP environment), the room where the HP is installed shall have a volume higher than: Unit refrigerant load in kg / 0,44kg/m3. If not, it must be ensured that:

- whether the room is mechanically ventilated,

- or room door is remain opened when the installer

works on the HP.

• Be careful not to bring inammable gas near to the heat pump during its installation, in particular when it requires brazing. The appliances are not reproof and should therefore not be installed in a potentially explosive atmosphere.

- To avoid condensation inside the condenser, remove the refrigerant circuit caps only when completing 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 refrigerant circuit and before nal connection, take care to replace the plugs in order to avoid any pollution from the refrigerant circuit (The sealing with tape is prohibited).

" This appliance uses refrigerant R410A.

Comply with the legislation for handling refrigerants.

3.1 Rules and precautions

" Connections must be made the day of the lling

the installation with gas (3.4, page 20).

• 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.

• Flared connections

" Lubrication with mineral oil (for R12, R22)

is forbidden.

- Only lubricate with polyolester refrigerant oil (POE). If POE is not available, t without lubrication.

Coat the ared surface

with POE refrigerant oil.

Do not use mineral oil.

• Brazing on the refrigerant circuit (if necessary)

- Silver brazing (40% minimum recommended).

- Brazing only under dry nitrogen internal ux.

• Remarks

- After every intervention on the refrigerant circuit and before nal connection, take care to replace the plugs in order to avoid any pollution from the refrigerant circuit.

- 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 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 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).

3.2 Shaping the refrigerant pipes

3.2.1 Bending

The refrigerant 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).

3.2.2 Creating the arings

- Cut the pipe to an appropriate length with a pipe-cutter without deforming it.

- Carefully deburr it, holding the pipe towards the bottom to avoid introducing lings into the pipe.

- Remove the ared connection nut situated on the valve to be connected and slip the pipe into the nut.

- Proceed to are, letting the pipe overow the aring tool.

- After aring, check the condition of the working radius (L). This must not show any scratch or trace of any fracturing. Also check the dimension (B).

3.4.3 Filling the installation with gas

If an additional charge is requires, add the

additional charge before lling the hydraulic unit with gas. Please refer to the para. "Additional

charge", page 22.

- 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 a hex key (counterclockwise direction) without forcing excessively against the stop.

- Remove the hose rapidly to the Manifold.

- Ret the 2 original caps (be sure they are clean) and

tighten them to the recommended tightening torque (gure 18, page 18). The sealing is performed in the caps only metal to metal.

The outdoor unit does not contain any additional refrigerant, enabling the installation to be purged.

Flushing is strictly forbidden.

3.4.4 Sealing test

The sealing test must be performed with a certied gas detector (sensitivity 5g/year).

Once the refrigerant circuit has been gassed as described above, check that all the refrigerant connectors are gas-tight (4 connectors). If the arings have been made correctly, there should be no leaks. Eventually, check the tightness of the refrigerant valves caps.

" If there is a leak:

- Bring the gas into the outdoor unit (pump down). The pressure should not drop below atmospheric pressure (0 bar to read on Manifold) so as not to contaminate the recovered gas with air or moisture.

- Make the connection again.

- Repeat the commissioning procedure.

Additional charge none 250 g

The charge in the outdoor units corresponds to the maximum distances between the outdoor unit and the hydraulic unit dened in page 19. If the distances are greater, an additional charge of R410A is required. The additional charge depends on the distance between the outdoor unit and the hydraulic unit for each type of appliance. The additional charge of R410A must necessarily be made by an approved refrigerant engineer.

• Example of additional charge :

An outdoor unit 17 m away from the hydraulic unit will require an additional charge of :

Additional charge = (17 - 15) x 50 = 100 g. The charge must be introduced after creating the

vacuum and before the hydraulic unit is lled with gas, as follows :

- Disconnect the vacuum pump (yellow hose) and connect a bottle of R410A instead in the liquid

extraction position.

- Open the bottle’s valve.

- Bleed the yellow hose by loosening it slightly on the

Manifold side.

" General

The connection must comply with good trade practice according to local building regulations.

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).

Use glycol if the ow temperature set [908-909 Settings] <10 ° C. If you are using a glycol/water mix, provide for an annual check on the quantity of glycol. Use monopropylene glycol only. The recommended concentration is 30% minimum. 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.

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

" It is also necessary to ensure that the treated

water does not become aggressive.

4.1 Connecting to the Heating circuit

4.1.1 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.

4.1.2 Connecting

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. Verify the correct functioning of the expansion system.

Control the vessel pressure (precharge 1 bar) and the safety valve setting.

The ow of the installation must be at least equal to the minimum value noted in the characteristics table (section 1.3, page 5). Do not instal any regulating appliance (without those present in our congurations) who's reduce or stop the ow through the hydraulic unit.

5.6 Outdoor sensor

The outdoor sensor is required for the heat pump to operate correctly.

Consult the tting instructions on the packaging. Place the sensor on the coldest part, generally the

northern or north-eastern side. In any case, it must not be exposed to the morning sun. It must be installed so as to be easily accessible but at

least 2,5 m from the oor. It is essential that it avoid any sources of heat such as

ues, the upper parts of doors and windows, proximity to extraction vents, the underneath of balconies and under-eave areas, which would isolate the sensor from variations in the outdoor air temperature.

- Connect the outdoor sensor to the connector X84 (terminals M and B9) on the heat pump control board.

5.7 Room thermostat

and/or room control unit

The room thermostat (room control unit) is optional. Consult the tting instructions on the packaging. The sensor must be installed in the living room area on

a very uncluttered wall. It must be installed so as to be easily accessible.

Avoid direct sources of heat (chimney/ue, television, cooking hobs), draughty areas (ventilation, door, etc.).

Air leaks in the seals in the constructions are often translated into cold air blowing through the electrical conduits. Lag the electrical conduits if there is a cold draught on the back of the IR sensor.

5.7.1 Installing a room sensor

• Room thermostat T55

- Connect the sensor to the X86 connector of the heat pump’s regulator board using the connector provided (terminals 1, 2).

• Room thermostat radio T58

- Please refer to the instructions .

5.7.2 Installing a room control unit

• Room control unit T75

- Connect the sensor to the X86 connector of the heat pump’s regulator board using the connector provided (terminals 1, 2 and 3).

• Room control unit radio T78

- Please refer to the instructions .

5.7.3 Fan convectors or dynamic radiators area

If the installation is equipped with fan convector or dynamic radiators, Do not use a room sensor in the

area.

6 Commissioning

- Close the installation's main circuit breaker. On rst commissioning (or in winter), in order to

allow the compressor to pre-heat, engage the installation's main circuit breaker (power supply to the outdoor unit) some hours before starting up the tests.

- Engage the start/stop switch. To ensure that inputs EX1, EX2 and EX3 operate

correctly: Check that the live-neutral polarity of the power supply is correct.

When the power is switched on and every time that the ON/OFF button is switched off and then switched on again, the outdoor unit will take approximately 4 minutes to start up, even if the setting is requesting heating.

The display can show error 370 when the appliance (re)starts. Do not be concerned, the communication between the outdoor and hydraulic unit will re-establish itself in a few moments.

During the regulator initialisation phase, the display shows all the symbols and then "Data, update" and then "State heat pump".

- Make all the specic adjustments to the setting.

(Installation conguration):

- Press OK.

- Hold down the key for 3s and select the level of

access used with the aid of the knob. .

- Conrm with the key OK.

- Parameter the heat pump's setting

(Consult the settings' list page 35).

On commissioning (or the case of error 10), the electrical back-up heaters are liable to start up even if the outdoor temperature at the time is above the heaters’ trigger temperature.

The regulating system uses an average initial outdoor temperature of 0°C and requires some time to update this temperature.

To avoid this situation, the sensor must be connected correctly. Re-initialise parameter 8703 (commissioning level, consumer diagnostic menu).

7.3 Temperature control

The heat pump's operation is subject to the temperature control.

The set temperature for the water in the heating circuit is adjusted according to the outdoor temperature.

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

7.3.1 Set to

During installation, the temperature control must be parametered according to the heat emitters and the dwelling's insulation.

The temperature control' curves (gure 47) efer to an ambient setting of 20°C.

The slope of the temperature control (parameter 720) determines the impact of the variations in the outdoor temperature on the initial heating temperature variations.

The higher the slope, the more a slight reduction in the outdoor temperature causes a signicant increase in the ow water temperature in the heating circuit.

The off-set in the temperature control (parameter 721) modies the initial temperature of all the curves, without modication of the slope (gure 48) .

The corrective actions in the case of any inconvenience are detailed in the table (gure 49).

gure 58 - Emptying the hydraulic unit

and/or Domestic hot water tank

Ensure that the general electrical power supply has been cut off before starting any repair work.

11.1 Hydraulic checks

" Warning : If frequent rells are required

it is essential that you look for any leaks.

If lling and re-pressurization are required, check what type of uid has been used initially.

Recommended lling pressure: 1 to 2 bar (Precise lling pressure is determined by the manometric height of the installation).

Each year,

- Check the expansion vessel pressure (precharge 1 bar) and the correct functioning of the safety valve.

- Verify the safety unit on the cold water supply inlet. Make it work as prescribed by the manufacturer.

- Check the shut-off.

- Verify the correct functioning of the distribution valve.

11.2 Maintenance of the DHW tank

Maintenance of the tank must be undertaken once a year (The frequency may vary according to water hardness).

11.2.1 Emptying the hot water tank

- Remove the facade from the hydraulic unit.

- Close the cold water entry into the tank.

- Open a hot water tap and open the water tank emptying

valve (ref. 1).

11.2.2 Descaling

- Empty the water tank.

- Remove the hood of the electrical back-up (ref. 2).

- Disconnect the electrical back-up.

- Unplug the ACI.

- Remove the electrical back-up (ref. 3).

- Remove any limescale deposits that have built up

inside the tank. It is best to let the scale stuck to the walls of the tank: it forms a protective layer.

- Gently remove any limescale deposit on the glove nger. Do not use any metal objects or chemical or abrasive products.

- Replace the joint of the electrical back-up (ref. 4) each time it is dismantled.

- Replace the electrical back-up and carry out ‘crossed’ locking of the nuts.

- Reconnect the electrical back-up.

- Plug in the ACI.

- Replace the hood of the electrical back-up.

4 3

11.3 Checking the outdoor unit

- Dust off the heat exchanger if necessary, being careful not to damage the ns.

- Straighten the vanes using a comb.

- Check that there is nothing obstructing the passage of air.

- Check the fan.

- Verify that condensate drain is not obstructed.

• Checking the refrigerant circuit :

- When the refrigerant charge is in excess of 2kg (>10kW models), it is compulsory to have an approved after sales service check the refrigerant circuit every year (with a certicate of capacity for the handling of refrigerants) (see para. 10.2, page 70).

- Check the lack of leak (connections, valves…).

11.4 Electrical checks

- Check connections and possible tightening.

- Check the cables condition and electronic boards.

- ACI light: In normal operation, the light ashes.
