Children must never play with the appliance. Cleaning and maintenance by the user may not be carried out by children unless they are supervised.– If using preheated water, the tap can reach a temperature of up to 70 °C during operation. There is a risk of scalding at outlet temperatures in excess of 43 °C.– The appliance is suitable for supplying a shower (shower operation). If the appliance is also or exclusively used for shower operation, the qualified contractor must adjust the temperature setting range to 43 °C using the internal anti-scalding protection on the appliance. When using preheated water, ensure that the inlet temperature does not exceed 55 °C.– In Australia, the use of a temperature controller is required to meet the requirements of AS 3498 when showers, bathtubs or washbasins are supplied with water. The maximum temperature of 50 °C must not be exceeded.

OPERATION Appliance description
Any other use beyond that described shall be deemed inappropriate. Observation of these instructions and of the instructions for any accessories used is also part of the correct use of this appliance.
2.2 General safety instructions
CAUTION Burns If using preheated water, the tap can reach a temperature of up to 70 °C during operation. There is a risk of scalding at outlet temperatures in excess of 43 °C.
CAUTION Burns If operating with preheated water, e.g. from a solar thermal system, the DHW temperature may vary from the selected set temperature.
CAUTION Burns If children or persons with limited physical, sensory or mental capabilities use the appliance, a permanent and unchangeable temperature limit is necessary. Ask a qualified contractor to set the internal anti-scalding protection.
!
WARNING Injury The appliance may be used by children aged 3 and older
and persons with reduced physical, sensory or mental
capabilities or a lack of experience and know-how, pro-
vided that they are supervised or they have been in-
structed on how to use the appliance safely and have
understood the potential risks. Children must never play
with the appliance. Children must never clean the ap-
pliance or perform user maintenance unless they are
supervised.
!
WARNING For continued safety of this appliance it must be in-
stalled, operated and maintained in accordance with
the manufacturer’s instructions.
3. Appliance descriptionThe appliance switches on automatically as soon as you open the hot water valve on the tap. When you close the tap, the appliance switches off again automatically.The appliance heats water as it flows through it. The set temperature is adjustable. Upwards of a certain flow rate, the control unit selects the required heating output, subject to the temperature selected and the cold water temperature.The electronically controlled instantaneous water heater with automatic output matching maintains a consistent outlet temperature. It is irrespective of the inlet temperature, up to the maximum output of the appliance.If the appliance is operated with preheated water and the inlet temperature exceeds the set temperature, the water is not heated further.Heating systemThe bare wire heating system is enclosed within a pressure-tested plastic jacket. The heating system with its stainless steel internal indirect coil is suitable for hard and soft water areas and is largely insusceptible to scale build-up. The heating system ensures rapid and efficient DHW provision.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.4. Settings and displays4.1 Selecting the set temperature

OPERATION Cleaning, care and maintenance
Selecting the temperature indicatorYou can choose to display the temperature in °C or °F, as required. f Turn the temperature selector anti-clockwise, past the OFFindicator and another five complete turns, until you find yourself in temperature unit selection mode. Then select the temperature unit using the temperature selector. After 30 seconds, the appliance exits selection mode automatically and the selected temperature unit is retained.Note If the outlet temperature is not high enough when the draw-off valve is fully open and the temperature selector is set to maximum, then more water is flowing through the appliance than can be heated by the heating system (appliance working at maximum output). f Reduce the water volume until the preferred tem-perature delivery is achieved.4.2 Recommended settingsYour instantaneous water heater offers maximum precision and maximum convenience in DHW provision. Should you nonetheless be operating the appliance with a thermostatic valve, we recommend that you: f Adjust the set temperature on the appliance to over 50 °C.Then set the required set temperature on the thermostatic valve.Saving energyThe following recommended settings will result in the lowest energy consumption: – 38 °C for hand washbasins, showers, bath – 55 °C for kitchen sinksTemperature limit via internal anti-scalding protection (qualified contractor)If required, the qualified contractor can set a permanent temperature limit, for example in nurseries, hospitals etc.Limiting it in this way prevents water from flowing out of the appliance at temperatures which could cause injury.Recommended setting for operation with a thermostatic valve and water preheated by solar energy f Set the temperature at the instantaneous water heater to themaximum temperature.Following an interruption to the water supply
5. Cleaning, care and maintenancef Never use abrasive or corrosive cleaning agents. A damp cloth is sufficient for cleaning the appliance.f Check the taps regularly. Limescale deposits at the tap outlets can be removed using commercially available descaling agents.

INSTALLATION Safety
INSTALLATION7. SafetyOnly a qualified contractor should carry out installation, commissioning, maintenance and repair of the appliance.7.1 General safety instructionsWe guarantee trouble-free function and operational reliability only if original accessories and spare parts intended for the appliance are used.! Material losses Observe the maximum inlet temperature. Higher temperatures may damage the appliance. You can limit the maximum inlet temperature by installing a central thermostatic valve (see chapter “Appliance description / Accessories”).WARNING Electrocution This appliance contains capacitors which are discharged when disconnected from the power supply. The capacitor discharge voltage may briefly exceed 60 V DC.7.2 Shower operationCAUTION Burns – The appliance is suitable for supplying a shower(shower operation). If the appliance is also or exclusively used for shower operation, the qualified contractor must adjust the temperature setting range to 43 °C using the internal anti-scalding protection on the appliance. When using preheated water, ensure that the inlet temperature does not exceed 55 °C. – In Australia, the use of a temperature controller is required to meet the requirements of AS 3498 when showers, bathtubs or washbasins are supplied with water. The maximum temperature of 50 °C must not be exceeded.7.3 Instructions, standards and regulationsNote Observe all applicable national and regional regulations and instructions.
– The specific 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 resistance of the water. Your water supply utility will advise you of the specific electrical water resistance or conductivity.8.
