2.1 Intended useThis appliance is intended for domestic use. It can be used safely by untrained persons. The appliance can also be used in a non-domestic environment, e.g. in a small business, as long as it is used in the same way.This pressurised appliance is suitable for heating domes-tic hot water or for reheating preheated water. The appli-ance can supply one or more draw-off points.Any other use beyond that described shall be deemed inappropriate. Observation of these instructions and of instructions for any accessories used is also part of the correct use of this appliance.2.2 General safety instructions CAUTION BurnsDuring operation, the tap can reach temperatures in excess of 60 °C.There is a risk of scalding at outlet temperatures in excess of 43 °C. CAUTION BurnsIf operating with preheated water, e.g. from a solar thermal system, the DHW temperature may vary from the selected set temperature.

WARNING InjuryThe appliance may be used by children aged 8 and up and persons with reduced physical, sensory or mental capabilities or a lack of experience and know-how, provided that they are supervised or they have been instructed on how to use the appliance safely and have understood the resulting risks. Children must never play with the appliance. Children must never clean the appliance or perform user mainte-nance unless they are supervised.Where children or persons with limited physical, sensory or mental abilities are allowed to use this appliance, we recommend a permanent temperature limit. A qualied contractor can set the limit for you.

Material lossesThe user should protect the appliance and its tap against frost.2.3 CE designationThe CE designation shows that the appliance meets all essential requirements according to the:

3. Appliance description

The electronically controlled instantaneous water heater with automatic output matching keeps the outlet temper-ature constant up to the output limit. The temperature is then selected via the draw-off tap.Heating systemThe bare wire heating system has a pressure-tested plas-tic casing. The heating system is suitable for hard and soft water areas. This heating system has a low susceptibility to scale build-up. This system ensures rapid and efcient DHW availability. Note The appliance is equipped with an air detector that largely prevents damage to the heating system. If, during operation, air is drawn into the appliance, the appliance shuts down for one minute, thereby protecting the heating system.

The DHW outlet temperature can be variably adjusted.Hand wash basin (approx. 35 °C)Shower (approx. 40 °C)Bath (approx. 45 °C)Kitchen sink (approx. 55 °C) » Turn the temperature selector to the required temperature.Temperature limitYour qualied contractor can set a temperature limit of up to 43 °C inside the appliance. With the temperature limit enabled you can turn the temperature selector across its full range. You can now set the outlet temperature only between 30 °C and 43 °C. Note Should the outlet temperature fail to reach the re-quired level with the draw-off valve fully open and the temperature selector set to maximum, then more water is owing through the appliance than can be heated by the heating system. The appliance is at its output limit. » Reduce the water volume at the draw-off valve.Recommended setting for operation with a thermostatic valveSet the temperature at the appliance to the maximum temperature.Following an interruption of the water supply

Material lossesIn order to prevent the destruction of the bare wire heating system, return the appliance into use follow-ing an interruption of the water supply as follows: » Disconnect the appliance from the power sup-ply by removing the fuses/tripping the MCBs. » Open the tap for one minute until the appliance and its upstream cold water inlet line are free of air. » Switch the mains power back ON again.

5. Cleaning, care and

maintenance » Never use abrasive or corrosive cleaning agents. A damp cloth is sufcient for cleaning the appliance. » Check the taps regularly. Limescale deposits at the tap outlets can be removed using commercially avail-able descaling agents.

Problem Cause RemedyThe appliance will not start despite the DHW valve being fully open.There is no voltage at the appliance. Check the fuses/MCBs in your fuse box/distribution panel.

The flow rate is too low. The aerator in the tap or the shower head is scaled up or contaminated.Clean and/or descale the aerator or shower head. Required tempera-ture > 45 °C is not achieved. The water supply has been interrupted.

Vent the appliance and the cold water inlet line (see chapter "Operation / Set-tings").

The cold water inlet temperature is > 45 °C.Reduce the cold water inlet temperature. If you cannot remedy the fault, notify your qualied contractor. To facilitate and speed up your enquiry, please provide the serial number from the type plate (000000-0000-00000): Nr.: 000000-0000-00000 D000004161420 Installation – for qualied contractors INSTALLATION

Only a qualied contractor should carry out installation, commissioning, maintenance and repair of the appliance.7.1 General safety instructionsWe guarantee trouble-free function and operational relia-bility only if original accessories and spare parts intended for the appliance are used.

Material lossesObserve the maximum inlet temperature. Higher temperatures may damage the appliance. You can limit the maximum inlet temperature by installing a central thermostatic valve.7.2 Instructions, standards and regulations Note Observe all applicable national and regional regula-tions and instructions. ◦ The protection rating IP 25 (hoseproof) can only be ensured with a correctly tted cable grommet. ◦ The specic electrical resistance of the water must not fall below that stated on the type plate. In a linked water network, factor in the lowest electrical resist-ance of the water (see chapter "Installation / Spec-ication / Data table"). Your water supply utility will advise you of the specic electrical water resistance or conductivity.
