Package package: Outside unit package: hydraulic module and outdoor sensor. Definitions Split: The heat pump consists of two elements (an outside unit for outside and a hydraulic module 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 (coefficient of performance): this is the relationship between the energy transmitted to the heating circuit and electrical energy consumed. 4 Installation and operating manual 50-EN

The heat pump consists of four main elements, in which a refrigerant fluid (R40A) circulates. - In the evaporator (rep., fig 7, page ): 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 -5 C outside temperature). - In the compressor (rep. 0, fig 7, page ): The vaporised refrigerant brought to high pressure and takes on more calories. - In the condenser (rep. 5, fig 8, page ): The energy in the refrigerant is transmitted to the heating circuit. The refrigerant returns to liquid state. - In the expansion valve (rep. 9, fig 7, page ): The liquefied 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 internal temperature based on the outside temperature measurement and governed by the temperature control. The room thermostat (optional) provides a corrective action for the temperature control The hydraulic module is equipped with an electric back-ups system, which is triggered to provide additional heat during the coldest periods. Regulation functions - The heating circuit s initial temperature is controlled by the temperature control. - The power of the outside unit is modulated according to initial heating temperature via the inverter compressor. - Control of the electric back-up heating. - The daily timer program enables you to define the periods for comfortable or reduced ambient temperature. - Summer/winter mode switchover is automatic. - Control of the supplementary boiler* (the electric back-ups are deactivated). - The room thermostat* (optional) provides a corrective action for the temperature control - Control of a second heating circuit*. - Domestic hot water: Heating time programme, control of the operation of the DHW circulation pump. - Control of swimming pool heating*. Protection functions - Anti-legionella cycle for domestic hot water. * If the heat pump is equipped with optional equipment and the associated kits. Installation and operating manual 50-EN

13 Domestic hot water (DHW) operating principle Two domestic hot water (DHW) temperatures can be parametered: comfort temperature (line 60 to 60 C) and reduced temperature (line 6 to 40 C). 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 504) below the set temperature. The heat pump produces the domestic hot water, which is then supplemented, if required, by electrical backup heating from the tank. Depending on how the parameter (60) is set, comfort temperature can be reached 4h/day or only at night or depending on the heat pump programme. 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 DHW boost function is available on the front of the user interface (see ref., fig. 9, p ). This DHW boost enables the DHW to be heated to the comfort temperature at any time during the day. The boost function is cancelled automatically when the demand for hot water has been met. If the heating installation is equipped with a DHW circulation pump, the pump s operation during DHW cycles can be parametered. Anti-legionella cycles can be programmed.

14 Installation. 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.. Unpacking and reservations.. Receipt Carefully check, in the carrier s presence, the general appearance of the appliances and check that the outside 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... Handling The outside unit should not be laid on its side or back during transport. Laying the unit down during transport is likely to damage the internal tubes and the compressor suspensions. Any damage caused by transportation of the unit lying down is not covered by the warranty. If necessary the outside 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. 4.. Accessories provided Accessories provided with the outside unit (figure 0). Accessories provided with the hydraulic module (figure ). 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 qualified person. Choose the site of the outside unit and the hydraulic module after discussion with the customer. Observe the maximum and minimum distances between the hydraulic module and the outside unit (Figure ); the guarantee of the performances and the system s service life depend on this..4 Installation of the outside unit.4. Installation precautions The outside unit must only be installed outside (outdoors). If a shelter is required, it must have broad openings on the 4 walls and observe the installation clearances (fig. ). 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 (fig. ).

15 The outside unit is able to withstand bad weather but avoid installing in a position where it is likely to be exposed to significant dirt or flowing water (under a defective gutter for example). Water may drain away from the outside unit when it is operating. You can let this defrosted water run off over a gravel or sand bed or a concrete slab with a diamond point and a sinkhole in the ground. 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 outside unit (see.4., page 6). Nothing should obstruct the air circulation through the evaporator and from the fan (fig. ). Keep the outside unit away from heat sources and inflammable 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 receiving the outside unit must be able generally to support its weight; provide a solid fixing and do not transmit any vibration to the dwelling. Anti-vibratory blocks are available, please consult your retailer.

17 .5 Installing the hydraulic module.5. Installation precautions 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 sufficient space all around the hydraulic module (figure 5). Be careful not to bring inflammable gas near to the heat pump during its installation, in particular when it requires brazing The appliances are not fireproof and should not therefore be installed in a potentially explosive atmosphere..5. Positioning the hydraulic module -,, : Remove the front panel ( screws A, figure 6) - 4, 5 : Remove the sides (4 screws B, figure 7). - Fix the support solidly ( screws and plugs) to a flat, hard-wearing wall (not a light partition) ensuring that it is correctly levelled. - Hook the appliance onto its support. - Refit the sides. - Refit the front facing. 50 mm 00 mm 50 mm 000 mm A Figure 5 - Minimum installation clearances around the hydraulic module and distances to the combustible partitions Figure 6 - Removing the front facing 5 B 00 mm 505 mm 4 (S) 50 mm 90 mm 05 mm 5 B 40 mm (S) Figure 7 - Removing the sides and fixing the support (S) Installation and operating manual 50-EN 7

18 .6 Refrigeration connections This appliance uses refrigerant R40A. Comply with the legislation for handling refrigeration fluids. Flaring tool L B.6. Rules and precautions Flare nut After every intervention on the refrigeration circuit and before final 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 (Hydrofluorocarbons). - Vacuum pump specially for HFCs. - Provision on using tools that have been in contact with HCFCs (R for example) or CFCs. - Use of a traditional vacuum pump is authorized if, and only if, it is fitted 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 R, R) is forbidden. - Only lubricate with polyolester refrigeration oil (POE). If POE is not available, fit without lubrication. Brazing on the refrigeration circuit (if necessary) - Silver brazing (40% minimum recommended). - Brazing only under dry nitrogen internal flux. To eliminate any filings 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 insulating sleeves resistant to temperatures over 0 C. In addition if the humidity level in the areas where the refrigeration pipes pass risks exceeding 70%, protect the pipes with insulating sleeves. Use a sleeve thicker than 5mm if the humidity reaches 80%, and a sleeve thicker than 0mm 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 insulating sleeves whose thermal conductivity is W/mK or less when the temperature is 0 C. The insulation must be impermeable to resist the passage of steam during the defrosting cycles (fibreglass wool is prohibited). Ø Hose 6,5 (/4 ) 5,88 (5/8 ),8.6. Refrigeration connections The outside unit must be connected to the hydraulic module with copper pipes and connections (refrigeration quality), insulated separately. Comply with the pipe diameters and the permitted pipe lengths (figure ). The minimum length of the refrigeration connections is 5m for correct operation (except model 050 and 065, see Figure ). The appliance will be excluded from guarantee if it is used with refrigeration connections less than 5m long (models 080, 095, 8, 55). Manipulate the pipes and take them through walls with protective plugs in place. If the distance between the outside unit and the hydraulic module exceeds the length of the maximum conduits indicated in the table, an additional charge of R40A must be loaded. The quantity of R40A added must be adapted to the length of the refrigeration circuit in order to the heat pump s performance without damaging the compressor (figure )..6. Creating the flarings - 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 filings into the pipe. - Remove the flared connection nut situated on the valve to be connected and slip the pipe into the nut. - Proceed to flare, letting the pipe overflow the flaring tool. - After flaring, check the condition of the working radius (L). This must not show any scratch or trace of any fracturing. Also check the dimension (B).

19 .6.4 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 times in the same position otherwise traces of fracturing may appear (from strain-hardening the metal)..6.5 Connecting the flared connections The small pipe must always be connected before the large one. Take particular care positioning the tube opposite its connector so as not to risk damaging the threads. A carefully aligned connector can be fitted 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.

21 .7 Filling the installation with gas This operation is reserved for installers familiar with the legislation for handling refrigeration fluids. Creating a vacuum with a vacuum pump is essential. Never use equipment used beforehand with any refrigerant other than a HFC. Low pressure Manometer kit (manifold) Lo Hi High pressure Vacuum meter Vacuum pump.7. Creating a vacuum and filling the refrigeration connections with gas (see figure ). - Remove the protective plugs (B) from the charging hole (Schrader) in the gas valve (large diameter). - Connect the blue hose (on the side with a valve pusher in good condition) from the set of manometers (manifold). - Connect the yellow hose to a vacuum pump and open the blue valve on the set of manometers. - Create a vacuum until the residual pressure in the circuit falls below 0.0 bar. - Let the pump continue to operate for another 5 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. - Wait 0 minutes. If the pressure rises during this 0-minute period, there is a leak in the circuit. Trace it and repair it: then start again. When the pressure has remained stable for 0 minutes after the vacuum pump stops, the circuit is considered to be gas-tight. - Remove the access plugs (A) from the valve controls. If an additional charge is requires, add the additional charge before filling the hydraulic module with gas. Please refer to the section ( Additional charge, page ). - 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. - Refit the plugs and tighten them to the recommended tightening torque (see figure ). The outside unit does not contain any additional refrigerant, enabling the installation to be purged. Flushing is strictly forbidden.

Additional charge The charge in the outside units corresponds to the maximum distances between the outside unit and the hydraulic module defined in Figure. If the distances are greater, an additional charge of R40A is required. The additional charge depends on the distance between the outside unit and the hydraulic module for each type of appliance (Fig. ). The additional charge of R40A must necessarily be made by an approved refrigeration engineer. Example for a heat pump model 55 An outside unit m away from the hydraulic module will require an additional charge of: Additional charge = ( - 0) x 40 = 480 g The charge must be introduced after creating the vacuum and before the hydraulic module is filled with gas, as follows: - Disconnect the vacuum pump (yellow hose) and connect a bottle of R40A instead in the fluid 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 0g. Note the weight. - Carefully open the blue valve slightly and check the valueshownonthescales. - As soon as the value displayed has dropped by the value for the calculated additional charge, close the bottle and disconnect it. - Then rapidly disconnect the hose connected to the appliance. - Proceed to fill the hydraulic module with gas. Warning Only use R40A! Gas Fluid R40A Figure 4 - Gas bottle R40A Only use tools suitable for R40A (set of manometers). Always charge in the fluid phase. Never exceed the length or the maximum difference in level. Installation and operating manual 50-EN

23 .8 Connecting the heating circuit hydraulically.8. General The connection must comply with good trade practice according to local building regulations. The heating circulating pump is built into the hydraulic module. Connect the central heating pipes to the hydraulic module, complying with the direction of circulation. The diameter of the pipes between the hydraulic module and the heating collector must be at least inch (4x6mm). Calculate the diameter of the pipes according to the flow rates and the lengths of the hydraulic systems. Tightening torque :5to5N.m Use union connectors to facilitate removing the hydraulic module. 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 fitting in accordance with prevailing trade practice for plumbing work: - Use suitable seals (fibre seals, o-rings). - Use Teflon 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. 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..8. Rinsing out the installation Before connecting the hydraulic module 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, paraffin, etc.). In the case of an old installation, provide a sufficiently 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 filling it definitively..8. Filling and purging the installation Check the pipe fixings, the tightness of the connectors and the stability of the hydraulic module. Check the direction in which the water is circulating and that all the valves open. Proceed to fill the installation. Do not operate the circulating pump while filling. Open all the drain valves in the installation and the bleed valve for the hydraulic module to remove the air contained in the conduits. Close the drain and bleed valves and add water until the pressure in the hydraulic circuit reaches.5 bar. If the pressure is lower than 0,5 bar, the Heat Pump stops and posts error 69. 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 p. 0), once the machine has started, purge the hydraulic module again ( litres of water).

Characteristic of the electrical supply The electrical installation must be conducted in accordance with the prevailing regulations. The electrical connections must only be made when all the other fitting operations have been completed (fixing, assembly, etc.). Warning The contract concluded with the energy provider must be sufficient not only to cover the heat pump s power but also the combined sum of all the appliances likely to be operating at the same time. When the voltage is too low, check with your energy provider the value subscribed to in your contract. Never use a socket for the power supply. The heat pump must be supplied with power by special protected leads from the electric panel via -pole circuit breakers specially dedicated to the heat pump: Curve D for the outside unit, curve C for the electric heating and domestic water back-ups (see tables on page 5). The electrical installation must necessarily be equipped with a 0mA differential protection. Use a flexible cable of H07 RN-F type. This appliance is intended to operate under a nominal voltage of 0V +/- 0%, 50 Hz..9. General remarks on electrical connections Tighten the screws on the terminal blocks perfectly. Unsufficient tightening can cause overheating, leading to breakdown or even a fire. Use cable clamps to prevent the conductors from being disconnected accidentally. Connection to Earth and Earth bonding continuity are essential. Connecting to screw terminals Rigid wires (A,fig.8). Rigid wires are always preferable for fixed installations, particularly in a building. - Always select a wire that complies with the prevailing standards. - Strip away around 5 mm from the end of the wire. - With round end pliers, form a loop with a diameter corresponding to the tightening screws on the terminal. - Tighten the terminal screw firmly onto the loop created.

Consult the fitting instructions on the sensor s 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.5m from the floor. It is essential that it avoid any sources of heat such as flues, 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 outside air temperature. - Connect the outdoor sensor to the M and B9 terminals on the heat pump control board (fig. 8, p. 9).. Room thermostat and/or remote control The room thermostat (remote control) is optional. Consult the fitting instructions on the sensor s packaging. The sensor must be installed in the living room area on a very uncluttered wall,.5m above the floor. Avoid direct sources of heat (chimney/flue, 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. Installation equipped with two room thermostats Installation and operating manual 50-EN 9
