4 Description of the product
4.1 General description
The TWH 200 EV water heater has the following specifications:
Floor-standing thermodynamic storage water heater Thermodynamic unit extracting energy from the air Remote control panel (wireless) with display of the volume of heated water and timer programming Steatite immersion heater (2.4 kW) Enamelled tank, protected by impressed current anode Very thick insulation (0% CFCs)
The thermodynamic water heater is a hot water tank heated by:
The heat pump (up to 65°C) The immersion heater (Electrical back-up – AUTO and BOOST mode) (up to 75°C)
Management of the energy consumption:
To provide energy savings, the water heater is designed to be connected to a day/night or HP/HC switch. This switch will authorise the water heater to automatically start up at the energy provider's scheduled off-peak rate, therefore at the lowest tariff. The switch has three positions enabling the water heater to run in auto or continuous mode, or be switched off.

4.3
Operating principle
The thermodynamic water heater groups the domestic hot water tank and controlled mechanical ventilation functions. The calories contained in the air extracted from the building are used for the production of domestic hot water.
The refrigerant circuit is a closed circuit in which the R-134a refrigerant plays the role of an energy carrier.
The heat from the intake air is transferred to the refrigerant in the finned heat exchanger at a low evaporation temperature.
The refrigerant is drawn in, in vapour form, by a compressor which raises it to a higher pressure and temperature and sends it to the condenser. In the condenser, the heat extracted in the evaporator and some of the energy absorbed by the compressor are released into the water.
The refrigerant is depressurised in the thermostatic expansion valve and then cooled. The refrigerant can again extract the heat contained in the intake air from the evaporator.

Adjustable feet Basic dimension: 4 mm Possible adjustment: from 4 mm to 21 mm
5.6 Water connections
Caution Before attaching the water connections, it is essential to flush the circuits to remove any particles which risk causing damage to certain components (safety valve, pumps, valves, etc.). If flushing has to be done using an aggressive product, neutralise the rinsing water before disposing of it in the waste water network.
Important Using hoses which are too short or too rigid encourages the transmission of vibrations and the production of noises.
5.6.1 Connecting the water heater to the domestic water circuit
When making the connection, it is imperative that the standards and corresponding local directives be respected.

Specific precautions
Caution Do not connect the domestic hot water connection directly to copper pipes in order to prevent galvanic couplings in iron/copper (risk of corrosion). It is compulsory to fit the domestic hot water connection with a dielectric union (provided).
Safety valve or safety unit
Caution
Germany: In accordance with the safety regulations, a safety unit calibrated to 0.6 MPa (6 bar) must be fitted on the domestic cold water inlet on the domestic hot water tank. Belgium: In accordance with the safety regulations, a safety unit calibrated to 0.7 MPa (7 bar), and approved by Belgaqua, must be fitted on the domestic cold water inlet on the domestic hot water tank. Other countries: In accordance with the safety regulations, a safety unit calibrated to 0.7 MPa (7 bar) must be fitted on the domestic cold water inlet on the domestic hot water tank.
We recommend NF-marked hydraulic diaphragm safety units. Integrate the safety valve in the cold water circuit. Install the safety valve close to the water heater in a place with easy access.
Sizing
The diameter of the safety unit and its connection to the water heater must be at least equal to the diameter of the domestic cold water inlet on the water heater.
There must be no cut-off devices between the safety valve or unit and the water heater. The discharge pipe in the safety valve or unit must not be blocked.
To prevent the flow of water being hindered or obstructed in the event of a pressure surge:
The discharge pipe from the safety unit must have a continuous and sufficient gradient, and its cross section must be at least equal to the cross section of the opening of the safety unit outlet (to prevent the flow of water being hindered if the pressure is too high). The cross section of the discharge pipe from the safety unit must be at least equal to the cross section of the opening on the safety unit outlet
Pressure reducer
If the supply pressure exceeds 80% of the safety valve or unit calibration (e.g.: 0.55 MPa/5.5 bar for a safety unit calibrated to 0.7 MPa/7 bar), a pressure reducer must be located upstream of the appliance.
Install the pressure reducer downstream of the water meter in such a way as to ensure the same pressure in all of the system's pipes.
Measures to take to prevent hot water flow return
Fit a non-return valve to the domestic cold water circuit.

2. Attach the run-off collector.
5.9
Fitting and connecting the control module
The regulator control module is not fitted on the water heater when delivered, so that it can be installed in one of the living areas, to make it easier to use.
This control module can be installed remotely with a wire or radio connection, or integrated.
5.9.1 Radio connection (installation strongly recommended)
Fitting the control module
Warning Choose a location which enables good radio reception.
See To test the quality of the radio reception, see the section: “Radio test menu”.
