5.1 – Placement and positioning
5.1.1 – Placement choice

INSTALLATION PRECAUTIONS:

• The appliance must not be installed near a perpetual fl ame or other source of ignition.

• The appliance must be installed in such a way as to avoid mechanical damage.

• It is FORBIDDEN to install the appliance:
  – outside.
  – in an enclosed and unventilated space of less than 2m 3.
  – in rooms exposed to frost, or where the temperature is less than 5°C, including when the appliance is in operation.
  – in humid rooms with signifi cant vapour emissions (eg. a bathroom).
  – to operate the appliance with air intake which contains solvents or flammable materials.

• Avoid placing near bedrooms to reduce noise pollution.

5.1.2 – Positioning and anchoring

• To ensure normal operation of the Domestic hot water heat pump and to facilitate maintenance work, it is necessary to respect a minimum amount of free space around the appliance as well as a minimum ceiling height to allow for the removal of the cover.

Non-authorised mounting zones for thermodynamic water heaters 200 & 270 l:
Envelope volume:
The envelope volume is the volume that is outside the bathtub or shower cabin and is limited, on the one hand, by the vertical cylindrical surface circumscribed to the bathtub or shower cabin and, on the other hand, to the horizontal plane located at 2,25m from the bottom of the bath or shower basin.
Protection volume:
The protection volume is the same height as the envelope volume, but with an additional 1 metre of space added to its width (from the edge of the bathtub or shower cubicle) so that a person in the shower cubicle or bathtub may not reach out and touch the appliance or any electrical connections.

• The floor must be able to support the weight of the full water heater (weight of domestic hot water heat pump when fi lled with water 200 L/ 270 L= 246 kg / 324 kg).

For this purpose, use the three adjustable feet provided in the documentation bag of the installation manual (see below). 5.1.3 – Options
5.1.3.1 – Primary circuit mixing valve Primary circuit thermostatic mixing valve > 50°C ref: 730010
5.1.4 – Included accessory
5.1.4.1 – Hydraulic derivation module

Hydraulic derivation module réf: B4591222

5.2 – Hydraulic connections to the underfloor heating circuit
The appliance is connected using the return fl ow of the underfl oor heating network via a derivation module provided with the tank.
5.2 .1 – Underfloor heating derivation module
5.2.1.1 – Description
The floor derivation module is a hydraulic accessory which is delivered as standard with the heat pump, which allows the connection of the heat pump water heater to the water return flow from the underfloor heating circuit.
For water return over 50°C, installation of a primary circuit thermostatic mixing valve is necessary >50°C (See § Options).
5.2.1.2 – Underfloor heating derivation module circulator
Power consumption 10W; electrical current required 0.05AThe length and diameter of the plumbing inlet/outlet connection between the floor derivation module and the heat pump water heater must be adapted to the circulator so that the flow drawn from the floor is more than 250 l/h.
Example above without thermostatic mixing valve: with 20m of connection with an interior diameter of 14 mm, the total pressure drop is 2.00m for a fl owrate of 325 l/h.
5.2.2 – Filter
It is recommended to install a filter on the inlet piping of the water heater to protect the circulator and the plated heat exchanger.
5.2.3 – Radiators
The heat pump water heater is not compatible with a radiator circuit (the volume of water in the radiators is insufficient, and condensation will form on the surface of the radiators during the summer months).
5.2.4 – Minimum surface area for underfloor heating
To avoid operation of the heat pump using the electrical back-up instead of the heat pump, a minimum surface area for underfl oor heating should be respected according to the capacity of the appliance:

5.2.5 – 3-way mixing valve for underfl oor heating circuit
With the presence of a 3-way mixing valve (rep.16), it is imperative to place the derivation kit between the underfloor heating collector and the 3-way valve bypass as indicated on the diagram below: 5.2.6 – Thermostatic mixing valves equipping the water loops of the underfl oor heating circuit
If there are thermostatically controlled valves equipping the recirculating pumps for the underfloor heating circuit on the appliance, (rep.18), leave them permanently open (by manually opening them or by disassembling the thermostatic head).
The permanently irrigated flooring should have the minimum surface area necessary for the capacity of the appliance.
This is to avoid damaging the circulator equipping the heat pump water heater and limits the running of the electrical back-up instead of the heat pump.
5.2.7 – Underfl oor heating circuit circulator
To help the circulator equipping the heat pump water heater if it is distanced from the derivation module (long distance or the diameter of connection is too weak), let the underfl oor heating circuit circulator (rep.17) run permanently, summer and winter.
This allows to limit operation of the appliance using the electrical back-up instead of the heat pump.
5.2.8 – Treatment of the water in the heating circuit
It is MANDATORY to read the additional document concerning the quality of water used for fi lling the installation.This document is included with this manual as well as in the packet with the warranty information.
This document also contains information which is PERTINENT to the WARRANTY of the material.
If the domestic hot water heat pump is connected to an installation with existing underfl oor heating, it is necessary to thoroughly rinse and treat the installation.
5.2.9 – Filling water
The materials used for the production of a heating circuit have diff ering properties. These properties can create a phenomena of corrosion through the creation of a galvanic bridge in new installations as well as in older ones.
The filling of the water circuit must be done only with water from the domestic water network using untreated water (no softener).
Using water from any other source (well water, rain water, etc..) will render the warranty null and void.
5.2.10 – Treatment of the heating circuit
Central heating systems MUST BE CLEANED to eliminate debris (copper, fibres, soldering fluxes) related to setup and installation, as well as to avoid chemical reactions between the metals.
It is also important to TO PROTECT THE CENTRAL HEATING SYSTEM AGAINST RISKS OF: CORROSION, LIMESCALE, AND MICROBIAL DEVELOPMENT by using an APPROPRIATE corrosion inhibitor for all types of installations (steel or cast-iron radiators, underfl oor heating). PRODUCTS USED FOR THE TREATMENT OF HEATING WATER USED MUST COMPLY WITH ALL NATIONAL STANDARDS IN THE COUNTRY OF INSTALLATION.
We recommend the use of products in the SENTINEL range for preventative and curative treatment of the heating circuit.
For new installations : (less than 6 months old):
– Clean the installation with a universal cleaner to eliminate the debris from the installation (copper, fibres, soldering fluxes) Example: SENTINEL X300 or SENTINEL X800.
– Thoroughly rinse the installation until the water runs clear,  with no traces of impurities left.
– Protect the installation against corrosion with a corrosion inhibitor, example: SENTINEL X100. Or against corrosion and freezing with an inhibitor with an anti-freeze additive.
Example: SENTINEL X500 or SENTINEL R600.
For existing installations:
– Desludge the installation with a desludging product to eliminate any sludge from the installation.
Example: SENTINEL X400 or SENTINEL X800.
– Thoroughly rinse the installation until the water runs clear, with no traces of impurities left.
– Protect the installation against corrosion with a corrosion inhibitor, example: SENTINEL X100. Or against corrosion and freezing with an inhibitor with an anti-freeze additive. Example: SENTINEL X500 or SENTINEL R600.
Corrosion inhibitor:
– protects against the formation of limescale
– prevents «pinhole» type corrosion
– prevents in new installations,the formation of sludge and the proliferation of bacteria (in low temperature networks: algae)
– prevents the formation of hydrogen
– eliminates the sound of the generators
Treatment products from other manufacturers can be used if they guarantee that the product is appropriate for all the materials used in the appliance and off ers efficient resistance to corrosion. To find this information refer to their user manual.
5.2.11 – Purging the installation
The oxygen present in the air is extremely corrosive. Therefore, for a permanent purging of the installation to be effective, place automatic or manual air purgers at each high point of the installation, and manual purgers on each radiator.
RENDERING THE WARRANTY NULL AND VOID
All deterioration of the appliance due to an inappropriate quality of water and/ or the presence of corrosion in the absence of treatment products as described above, and/or an improper purging of air of the installation will render the warranty null and void.

• Connect the floor derivation module to the return fl ow of the underfl oor heating of the installation. Take care of the proper orientation of the check valve (see § «Underfl oor heating derivation module» and «Description»).

5.3 – Connection to the domestic water supply

• A new pressure-relief valve (not included) must be installed and set to 6 bars on the domestic cold water supply of the appliance. The use of a membrane valve is recommended. This valve must conform to all local and national standards.

• The pressure-relief valve should be installed as close as possible to the appliance’s cold water inlet and the water flow should never be hampered by any accessory (valve, pressure-reducer, etc.).

• The pressure-relief valve drainage outlet should be sized according to building regulations and standards and must never be obstructed. It should be connected to a vertically draining pipe, using a funnel which allows an open space of at least 20mm and which is at least equal in diameter to the appliance’s piping connection.

• The pressure-relief valve drainage outlet must be installed in a frost-free place and in a downward-sloping position.

• If the pressure of the domestic cold water supply is higher than 5 bars, a pressure-reducer should be installed above the pressurerelief valve near the starting point of the installation (a pressure of 4-5 bars is recommended).

• It is advised to fit a shut-off valve above the pressure-relief valve.

• For installations equipped with:
  – piping of a small diameter
  – ceramic plate valves
  A domestic water expansion vessel, or anti-hammer valves which are adapted to the installation should be installed as close as possible to the shut-off valve.

• The following materials should be used for the domestic hot water circuit:
  – copper
  – stainless steel
  – brass
  – plastic
  If the materials used in the domestic hot water circuit are incompatible, corrosion damage may occur.

• Domestic hot water pipes with a cast-iron or steel link, or with dielectric connections (not supplied) to avoid an iron/copper galvanic bridge.

• Thoroughly flush the supply line piping before connecting the appliance to the domestic installation so as not to introduce any particles, metallic or other, into the appliance.

• Respect the standards in eff ect in the country of use, notably domestic water regulations and pressure safety regulations.

• The maximum domestic hot water temperature at the distribution points should never surpass 50 oC for toilets, and 60 oC for other uses.
  Adequate thermostatic mixing valves should be installed to avoid risk of burns.

• The appliance must operate using water with a TH between 12°F and 30°F. In regions with extremely hard water (TH>25°F), it is recommended to treat water with a softener.

• Not following the conditions shown below, see DTU 60-1, will lead to the warranty of the tank to be rendered null and void (the values are given for a water at 20°C).

The warranty does not apply if any of these points have been neglected or if the water quality did not allow correct treatment within the legal framework or if regular inspections of the anode are not carried out.
The use of a recirculation pump is strongly discouraged. This appliance is not designed for use with a recirculation pump. Use of a recirculation pump will cause a signifi cant lowering of the temperature of the water in the tank.

5.4 – Electrical connections
Do not connect the heat pump water heater to the eletrical line of a pre- existing water heater which used the peak / off -peak hours contact.
The heat pump water heater must be permanently connected to the power supply, and the peak / off -peak control is done by either programming, or through the use of an independent cable.
Grounding is mandatory.
Power supply = 230V single phase + ground.
The power supply should comply with all regulations in eff ect in the country of installation, as well as the NFC 15-100 standard.
A method of disconnection which ensures a total power-cut in category III conditions should be installed in fixed piping in compliance with the installation rules.
Protect the appliance with:

• an 8A all-pole circuit breaker with a minimum 3mm contact opening.
• a protective 8A circuit breaker with a 30mA diff erential.

If the power supply cable is damaged it must be replaced by the manufacturer, their customer service technicians, or by a qualified technician to avoid any risk of injury or danger.
5.4.1 – Remove the top cover 5.4.2 – External control
Only an external connection using a voltage free «dry contact» is authorised, otherwise there is a risk of damaging the electronic circuit board.
It is discouraged to operate the Heat pump during peak hours so as to optimise its operation.
It is not necessary to connect the electricity metre’s timer switch to program the heat pump water heater for peak/off -peak time operation.
The appliance’s control panel can be used to program time slots for the heat pump water heater or for the electrical back-up to run (see § «Programming» for daily programming options).

5.4.2.1 – Peak / Off -peak hours contact
It is also possible to connect the electricity provider dry contact to  the heat pump water heater without using programming.
– Contact open = Load shedding
– Contact closed = Normal operation
The load shedding level can be selected and programmed for the appliance (see § «Load shedding»).
By default, the electrical back-up does not run during peak hours.
To access the electrical connections:

• Remove the cover and the shell.
• Remove the cover of the appliance by taking out the screws which fix the shell onto the lower part of the appliance.
• Remove the black protective cover from the electronics board.

5.4.2.2 – Electricity provider contact
To prevent the electrical back-up from running during peak hours, connect the dry contact originating from the electricity counter, to terminal 1.
– Contact open = Back-up not allowed to run
– Contact closed = Back-up allowed to run
By choosing load shedding level 0 or 1 (see § «Load shedding»), you stop the electrical back-up alone from running (load shedding =1) or the heat pump and the electrical back-up from running (load shedding = 0).

• Pass a 0.75mm² 2-wire cable with metal tips through a cable gland at the back of the appliance and bring the end of the cable around to the electronics board. The other end of the cable should be connected to the timer switch.
• Insert the 2-wire cable through a grommet from the electronics box.
• Connect the 2-wire cable to «Input 1» indicated on the electronics board, having removed the existing red bridge beforehand.

5.4.1.3 – Connection to the photovoltaic (PV) function This function enables the appliance to operate in auto-production mode, which means that it will use the energy produced by the PV function to supply the heat pump as well as the electrical back-up, and to heat the water in the tank.
The connection is made between the energy manager electrical box (not supplied) and connectors 1 and 2 on the electronics board.

• Remove the protective casing.
• Remove the black cover from the electronics board.
• Connect the PV function cable to connector 1 on the electronics board.
• If the PV function regulator has two control contacts, connect them to connectors 1 and 2 on the electronics board. See § « Electrical box electrical diagram » in the appendix.
• Terminal 1: a low level of electrical energy is produced by the PV function.
• Terminal 2: a high level of electrical energy is produced by the PV function.

CAUTION: Connectors 1 and 2 are for DRY CONTACTS ONLY. They must NEVER be connected to 230V.

SET-UP AND USE

Deterioration risk: it is imperative to fill  the tank with water before switching onthe appliance or connecting it to the electrical supply.

• Leave the appliance unplugged.
• Open the hot water valve located at the highest point of the installation.
• Open the cold water inlet located on the safety group.
• Fill the tank until water is coming out of the hot water vavle located at the highest point of the installation.
• Close the hot water valve

Before turning on the appliance, verify that the entire circuit is watertight.
The heat pump water heater operates primarily with the heat pump as long as the temperature of the water from the underfl oor heating return fl ow is between 18°C and 50°C. Once the temperature is lower than 18°C or over 50°C, the water is no longer heated by the heat pump, but by the electrical back-up.
The temperature of the domestic hot water provided by the heat pump is adjustable to up to 60°C.
In the case of high domestic hot water consumption, the heat pump water heater has a comfort function , t°C mini which increases the heating capacity when there is less than 1/3 of the tank’s volume left at over 38°C (see § « t°c mini -minimum temperature-»). There is also a setting to activate the electrical back-up if the heating time is too long (see § «max time»).
If more domestic hot water is required from time to time, the heat pump water heater has a « boost» function (activated by the user) which ensures that the water heats to the desired temperature (for example: 50°C) quickly with the help of the heat pump and electrical back-up. This function is deactivated as soon as the required temperature is reached (end of heating cycle).
From time to time, check that there are no alerts (in case of an alert, please refer to § «Error message codes»).

…/…

../…
→ In case of intervention on the refrigerant circuit:

1. Secure the area you will be working in.
2. Inform people of the potential danger involved in the work being carried out.
3. Check that the risk of infl ammation is minimised.
4. Avoid working in a confi ned space; the area must be suffi ciently ventilated.
5. Check the area with an appropriate leak detector before and during the work.
6. Place a CO2 or dry powder extinguisher near the work area.
7. Do not smoke.

7.1 – Water circuit
It is MANDATORY to read the additional document concerning the quality of water used for fi lling the installation.This document is included with this manual as well as in the packet with the warranty information.
This document also contains information which is PERTINENT to the WARRANTY of the material.
The pressure-relief valve should be activated regularly so as to eliminate limescale and check for blockages.
Inspect the domestic hot water heat pump’s hydraulic connections to ensure that they are all watertight.

7.2 – Water circuit for return flow from underfloor heating
The control of the water circuits is limited to the inspection of the fi lters and stopping up of any eventual leaks. Clean or replace clogged filters.
7.3 – Electrical maintenance
It is mandatory to periodically inspect for cleanliness and the absence of dust deposits on the eletrical power board and the electrical connection terminals:

• of the compressor;
• of the electrical resistance;

Also check the lug connections to ensure proper tightness. The frequency of inspection must be adapted according to the air quality: a dusty environment requires more frequent inspection, at minimum once per year.

• Check that the wiring is not subject to wear, corrosion, excessive pressure, vibration, contact with sharp edges or any other adverse effects due to its environment.
• Maintenance must also take into account the effects of long-term continuous vibration from components such as compressor and fan

Neglecting to clean the electronic circuit board and the electrical components could create a source of ignition.
7.4 – Drainage
When draining the tank, ensure that there is a suffi cient air intake at a high point of the tank so as to avoid any depressions in the tank.
Materials and products to avoid:
– brushes with steel bristles and steel wool pads
– scouring powder
– all bleach based or chloride products

1. Switch off the power supply.
2. Shut off the cold water inlet valve on the safety group and ensure there is an air intake valve on a high point of the appliance.
3. Open the hot water valves.
4. Set the safety group to the drainage position.

7.5 – Modification
Any modification of the appliance is prohibited. Any replacement of components must be done by a professional with original parts from the manufacturer.
7.6 – Decommissioning
7.6.1 – Leak detection
In the event of a prolonged absence with the power supply to the housing and the product disconnected, ask a qualified professional to drain the product or protect it from freezing.
Under no circumstances should potential ignition sources be used for the detection or detection of refrigerant leaks. A halogen flare (or other detector using an open flame) shall not be used.

• Electronic leak detectors may be used to detect refrigerant leaks, but for flammable refrigerants, sensitivity may not be adequate or may require recalibration.
• Ensure that the detector is not a potential ignition source and is suitable for the refrigerant used. Leak detection equipment must be set to a percentage of the lower flammability limit of the refrigerant and must be calibrated for the refrigerant used. The value of 25% of the lower flammable limit is used as the maximum.
• Liquid leak detectors are also suitable for use with most refrigerants but the use of chlorine-containing detergents should be avoided as chlorine can react with the refrigerant and corrode copper from the piping.
• If a leak is suspected, all open flames must be suppressed/extinguished.

7.6.2 – Removal and evacuation

• When opening the refrigeration circuit to perform repairs – or for any other purpose – conventional procedures must be used.

• For flammable refrigerants, it is important to use best practice as flammability must be considered.

• The following procedure must be followed :
  – Remove the refrigerant ;
  – Purge the circuit with inert gas ;
  – Evacuate to the atmosphere;
  – Purge with inert gas ;
  – Open the circuit by cutting or brazing.

• Refrigerant must be recovered in a suitable recovery bottle.

• The system must be purged with nitrogen without oxygen.

• This process may need to be repeated several times. Compressed air or oxygen should not be used to purge refrigerant systems.

• The purge of refrigerants must be performed by breaking the vacuum in the system with nitrogen without oxygen: By filling up until the working pressure is reached, an evacuation to the atmosphere, and finally by vacuum pulling.

• This process must be repeated until there is no more refrigerant in the circuit.

• When the last oxygen-free nitrogen charge is used, the circuit must be brought to atmospheric pressure to allow intervention.

• Ensure that the vacuum pump outlet is not near potential ignition sources and that ventilation is available.

7.6.3 – Charging process

• Ensure that contamination of diff erent refrigerants does not occur when using charging equipment. Hoses or lines should be as short as possible to minimize the amount of refrigerant they contain.
• Cylinders must be held in an appropriate position according to instructions.
• Make sure the refrigeration system is grounded before charging the system with refrigerant.
• Label the system when the load is complete (if not already done).
• Extreme precautions must be taken to not overload the refrigeration system.
• Before recharging the system, it must be pressure tested with the appropriate purge gas.
• The system must undergo a leak test at the end of the load but before commissioning. Another follow-up leak test must be performed before leaving the site.

7.6.4 – Decommissioning

• Before performing this procedure, it is essential that the technician knows the product and all its specifi cities.
• It is recommended to use best practices to ensure that all refrigerants are safely recovered. Before the task is performed, an oil and refrigerant sample must be taken in case an analysis is required before recycling the recovered refrigerant. It is essential that a power supply is available before the intervention begins.

a) Familiarize yourself with the product and how it works
b) Electrically isolate the system.
c) Before attempting the procedure, ensure that:
– mechanical handling equipment is diponible, if necessary, for the handling of refrigerant cylinders ;
– all personal protective equipment is available and used correctly ;
– the recovery process is being overridden at all times by a competent person.
– recovery equipment and cylinders comply with appropriate standards.
d) Perform a «pump down» on the appliance where possible.
e) If it is not possible to vacuum, make a manifold so that the refrigerant can be removed from various parts of the system.
f) Make sure the recovery bottle is on the scale before the start of fl uid recovery.
g) Start the recovery group and operate it according to the instructions.
h) Do not overfill bottles (no more than 80% in volume of liquid charge).
i) Do not exceed the maximum operating pressure of the cylinder, even temporarily.
j) Once the cylinders have been filled correctly and the process completed, ensure that the cylinders and product are removed from the site quickly and that all isolation valves on the product(s) are closed.
k) Refrigerant must not be loaded into another refrigeration system unless cleaned and verified.

7.6.5 – Recovery
When transferring refrigerant into the recovery bottles, ensure that only the appropriate bottles are used. Make sure you have enough bottles to recover the entire system load. All cylinders used are dedicated to the refrigerant recovered and labeled for it (i.e., special cylinders for refrigerant recovery). Cylinders must be complete with pressure relief valve, associated shut-off valves and in good working condition. Empty recovery cylinders are evacuated and, if possible, cooled prior to recovery.

• Recovery equipment must be in good working order with all instructions at hand and must be suitable for recovery of all refrigerants including, where applicable, fl ammable refrigerants. In addition, a set of calibrated scales must be available and in good working order.
• Hoses must be complete with leak-free disconnects and in good condition. Before using the recovery machine, verify that it is in good working order, has been properly maintained and that all associated electrical components are sealed to prevent ignition in the event of a refrigerant leak. Consult the manufacturer if in doubt.
• The recovered refrigerant must be returned to the supplier in the appropriate recovery bottle and the transfer note fi lled in correctly.Do not mix refrigerants in recovery units and especially not in recovery bottles.
• If compressors or compressor oils need to be replaced, make sure they have been vacuum pulled to an acceptable level to ensure they are not left in the flammable refrigerant lubricant. Vacuum pulling must be done before the compressor is returned to the supplier. Only electric heating of the compressor body should be used to accelerate this process. When oil is drained from a system, it must be done safely.

7.6.6 – Recycling and Disposal

• The product must be labelled indicating that it has been taken out of service and emptied of the refrigerant.
• The label must be dated and signed.
• Ensure that there are labels on the product indicating that it contains a flammable refrigerant.

Entrust the disposal of the packaging to the installer who installed the product.
The above symbol requires:
– Do not dispose of the product with the household waste.
– Dispose of the product at a collection point for used electrical and electronic equipment.

If necessary, the part or product should be returned to the manufacturer but only with prior agreement from our technical department. Labour, transport, and packaging costs are the responsibility of the user.
Repairs on a device will not result in compensation. The warranty for replacement parts ends at the same time as the appliance warranty (2 years).
The warranty only applies to the appliance and its components, and excludes any part or installation external to the appliance.
Regular maintenance of the appliance by a trained professional is essential for ensuring sustained use and durability. In the absence of regular maintenance, the warranty will not apply.
If an appliance is presumed to have been the cause of any damage, the appliance and the damage must be left as they are and not tampered with until an inspection can be carried out.
