3. USER INSTRUCTIONS

The device must be lled with water before connec- tion to the electrical supply! The device should always be connected to a safety unit!19 DE GB NL FR To ll the appliance: Open one of the hot water draw-off points connected to the wall boiler. Then open the tap in the inlet combination. When the water starts to ow out of the draw-off point the wall boiler has been lled. The device only switches on again if the temperature falls below this setting. (See troubleshooting) When lling for the rst time, the hot water valve in the low-pressure tap tting must be open so that water can ow into the device. If the device is not lled with water be- forehand during installation, the automatic safety device will activate and switch off the device. (See troubleshooting instructions on how to act in the event of a fault.) Temperature setting Turn the on/off button to switch the wall boiler on. The ‘ON’ light comes on. Turn the button on the right to set the required temperature. The ‘HEATING’ light will come on until the water has been heated. Stand Description Water is not heated LOW Water is moderately heated E Energy-saving position HIGH Water is heated to maximum temperature Usage and maintenance Please refer to the previous section for details of the thermostat settings. We recom- mend you use position „E“ as this guarantees maximum energy efciency and the low- est lime scale building. By maintaining the water temperature at approximately 55°C; furthermore lime scale build-up and heat loss are much lower than at higher tempera- tures. As the water that is used for washing the dishes has a temperature of approximately 45 to 50°C, cold water has to be mixed in to reach this temperature. At a water tempera- ture of 60°C, you will be able to draw off about 14 litres of 45°C. Operation of the device is indicated by the indicator light, which lights up when the de- vice is on and extinguishes when the set temperature is reached or the device is turned off.20 DE GB NL FR During heating, the volume of the water in the device expands, causing a ow of water („expansion water“) from the safety unit. This is perfectly normal and no preventive ac-tion needs to be taken. Frost When the device has not been used for an extended period, it must be protected against the effects of frost. Leave the power supply on and set the thermostat knob to „LOW“. When set to this position, the device maintains the water temperature at approximately 7°C. If the device is to be disconnected from the power supply, it must be emptied completely in order to avoid the risk of damage caused by freezing.

This device does not require any maintenance by the user. Professional maintenance should always be carried out by an expert. As water expands when heated, the pressure will increase in the device vessel with the connected hot water pipe(s). In order to limit this increase in pressure, a safety unit is required. This is a combination of a check valve, which prevents hot boiler water from owing into the cold supply pipe, with a relief valve that limits the pressure in the device to a maximum of 8 bar, and a Stop valve in front of the check valve in order to be able to disconnect the device from the water mains. The relief valve is provided with a discharge hose for discharging expansion water from the device to the sewer. The steel storage vessel is provided with an enamelled layer that prevents the formation of corrosion. In case of damage to the enamelled layer, a magnesium anode mounted in the storage vessel will make sure that the underlying steel is protected. The magnesium anode protects the tank against corrosion. This is a cathodic process, during which the anode slowly dissolves. The anode should therefore be inspected, and replaced if necessary, by a recognized tter every 2 years.Check the functioning of the inlet combination by turning the large knob on the inlet combination once a year, allowing water to ow out, and closing it immediately. This will prevent the valve of the inlet combination from getting stuck. Also check the drain for blockages. If it is blocked, unblock the drain or instruct a third party to do this. If faulty, never try to repair the device yourself. Please contact the nearest service specialist or the party that supplied the device originally.21 DE GB NL FR De-scaling A service inspection should be performed by authorized and qualied technical staff every year. De-scaling of the device during this inspection is highly recommended, es-pecially when you live in an area with hard water exceeding 12°dH (German standard of hardness). Higher water temperature will intensify calcication. It is therefore recom-mended to set the device at maximum 55°C (energy-saving setting) in areas with ex-tremely hard water >16°dH. Cleaning The housing of the device can simply be cleaned with a damp cloth. Do not use aggres-sive cleaners or cleaners with a scouring effect! Legionella prevention Do not use heated water as drinking water. After prolonged shutdown of the device for example due to holidays, the device should be fully heated up to the maximum temperature (tap at minimum ow) before re-using. It is recommended to ush the pipes for one minute.

Note: in case of problems, always consult the failure guide! If the water in the device is no longer heated, rst check whether the plug is properly connected to the wall socket and whether the fuse of the device group is still working. For all other failures, please consult the failure guide. If the device no longer works because it was connected without being lled with water rst, follow the troubleshoot- ing guide. The device has overheated and needs to cool down. If the device has been reset several times, but still does not work, please contact the party that supplied the device originally.22 DE GB NL FR Failure guide Complaint Connections water The safety unit hoses do not t There is a white substance in the water There is a grey or brown substance in the water Water leakage been tightened sufciently No water No hot water Plug is not connected Scale deposits in the ow regulator De-scale the ow regulator Water is too hot There is too little water coming from the tap There is steam coming out of the hot water tap The device makes boiling noises After installation, the tap makes bubbling noises Properly open and vent both valves Electricity The fuses are blown The earth leakage circuit breaker is activated Short-circuit The “ON“ lamp does not light Plug is not connected professionals: Pull out the plug and allow the side seen from the front.
