3. Appliance description

The hydraulically controlled instantaneous water heater heats water as it ows through the appliance. When a tap is opened, the heating output starts automatically as soon as the start-up volume is exceeded (see chapter "Speci-cation / Data table"). The water volume and temperature can be adjusted at the tap.You can choose between 2 output stages. In addition, 2 output stages are hydraulically controlled in relation to the ow rate.The ow rate controller compensates for pressure uc-tuations, thereby ensuring largely stable temperatures. The controller limits the throughput, thereby ensuring an adequate increase in the DHW temperature at all times.Heating systemThe bare wire heating system has a pressure-tested plas-tic casing. The heating system is suitable for hard and soft water areas and is largely insusceptible to scale build-up. This system ensures rapid and efcient DHW availability.

26_02_02_07832 11 Partial load At low throughput 1/3 of the heating output is activat-ed; at higher throughput 2/3 of the available heating output is enabled. This setting is suitable for hand washing at a basin, for example.2 Full load At a low throughput, 50 % of the heating output is ap-plied; at a higher throughput the full heating output is activated. This setting is suitable for washing dishes, for example. » Click the output selector into the required position.Recommended settings when using a thermostatic valve » Set the output selector to full power.4.1 Recommended tap/valve settings Note If the outlet temperature is not sufciently high at full load and with the draw-off valve fully open, then more water is owing through the appliance than can be heated by the heating system (appliance is at its output limit). » Reduce the water volume at the draw-off valve.Low draw-off rate = high outlet temperatureHigh draw-off rate = low outlet temperatureTwin lever tapOutput stage Application rangePartial load WashbasinFull load Bath, shower, sink » Add cold water if the temperature is too high when the tap is fully open.Mono lever mixerOutput stage Application rangeFull load All » Turn the tap lever to the highest temperature. » Fully open the tap. » Increase the outlet temperature by closing the tap slowly. » Reduce the outlet temperature by adding cold water or opening the tap further, if possible.Following an interruption of the water supply

Material lossesFollowing an interruption of the water supply the ap-pliance must be recommissioned by carrying out the following steps, in order to prevent the destruction of the bare wire heating system. » 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.19 Operation - for users and contractors

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 spouts can be removed using commercially available descaling agents.

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

The flow rate is too low for switching on the heating output. The aerator in the tap or the shower head is scaled up or contam- inated. Clean and/or descale the aerator or shower head.

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 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, observe the lowest electrical water resistance (see chapter "Specication / Application areas / Conversion table"). Your water supply utility will advise you of the specic electrical water resist-ance or conductivity.

11.1 Initial start-up

D0000041620 » Open and close all connected draw-off valves sever-al times, until all air has been vented from the pipe-work and the appliance. » Carry out a tightness check. » Activate the safety pressure limiter by rmly pressing the reset button (the appliance is delivered with the safety pressure limiter deactivated). » Fit the appliance cover, ensuring it clicks into place. Check that the appliance cover is seated correctly. » Switch the mains power ON. » Check the function of the appliance. Appliance handover » Explain the appliance function to users and familiar-ise them with its operation. » Make users aware of potential dangers, especially the risk of scalding. » Hand over these instructions.

11.2 Recommissioning

Vent the appliance and the cold water inlet line (see chap-ter "Settings").See chapter "Commissioning / Initial start-up".

12. Shutting down the system

» Isolate all poles of the appliance from the power supply. » Drain the appliance (see chapter "Maintenance").

Fault Cause RemedyThe flow rate is too low. The strainer in the ap-pliance is dirty.Clean the strainer. Flow meter will not start despite tap being fully opened. The start-up volume required to start up the heating output has not been reached.Clean the strainer.

The appliance is not generating hot water despite audible sound of the differential pres-sure switch starting.Safety pressure limiter (AP 3) has switched the appliance off for safety reasons. Remove the cause of the fault (e.g. faulty pressure washer).

Protect the heating system against over-heating by opening a draw-off valve down-stream of the appli-ance for one minute. This depressurises and cools down the heating system.

Activate the safety pressure limiter at flow pressure by pressing the reset button (see chapter "Commission-ing").

The heating system is faulty. Check the heating system resistor, and replace it if required.25 Installation - for contractors

WARNING ElectrocutionBefore any work on the appliance, disconnect all poles from the power supply. Draining the appliance The appliance can be drained for maintenance work. WARNING BurnsHot water may escape when draining the appliance. » Close the shut-off valve in the twin connector or the cold water inlet line. » Open all draw-off valves. » Undo the water connections on the appliance. » If dismantled, store the appliance in a room free from the risk of frost, as water residues remaining inside the appliance can freeze and cause damage. Cleaning the strainer 26_02_02_0949If dirty, clean the strainer in the threaded cold water tting. Close the shut-off valve in the cold water inlet line before removing, cleaning and retting the strainer.
