3. Appliance description

The hydraulically controlled small instantaneous water heater heats the water directly at the draw-off point. The heating system starts automatically when the tap is opened. The short pipe runs ensure that energy and water losses are minimall.The DHW output depends on the cold water temperature, the heating output and the ow rate.The bare wire heating system is suitable for hard and soft water areas. This heating system has a low susceptibility to scale build-up. The heating system ensures quick and efcient DHW provision at the hand washbasin.Fitting the special aerator supplied provides an optimum water jet.

The appliance heating system switches on automatically as soon as you open the DHW valve at the tap or activate the sensor of a sensor tap. The water is heated. The water temperature can be adjusted at the tap:For the start volume, see chapter "Specication / Data table / On".Increasing the temperature » Reduce the ow rate at the tap.Reducing the temperature » Open the tap further or add more cold water.Following an interruption of the water supplySee chapter "Commissioning / Recommissioning".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/valves regularly. Limescale deposits at the spouts can be removed using commercially available descaling agents. » Have the electrical safety of the appliance regularly checked by an electrician. » Regularly descale or replace the special aerator (see chapter "Appliance description / Accessories").

Problem Cause Remedy The appliance will not start despite the DHW valve being fully open. No power to the ap- pliance. Check the fuses/ MCBs in your fuse box. The aerator in the tap is scaled up or dirty. Clean and/or descale the aerator or replace the special aerator.

The water supply has been interrupted. Vent the appliance and the cold water inlet line (see chapter "Settings"). If you cannot remedy the fault, notify your qualied con- tractor. To facilitate and speed up your enquiry, please provide the serial number from the type plate (000000 / 0000-00000). MTD . . . Model:

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 max. permissible inlet temperature. Higher temperatures may damage the appliance. You can limit the inlet temperature by means of a central thermostatic valve.7.2 Instructions, standards and regulations Note Observe all applicable national and regional regula-tions and instructions.The specic electrical resistance of the water must not fall below that stated on the type plate. In a linked water net-work, factor in the lowest electrical resistance of the water (see chapter "Specication / Data table"). Your water sup- ply utility will advise you of the specic electrical water resistance or conductivity.

» Flush the water line thoroughly. Water installation A safety valve is not required. Taps » Use suitable taps (see chapter "Appliance descrip-tion / Accessories"). Note Fitting the special aerator supplied provides an op-timum water jet.

Install the appliance in a room free from the risk of frost and near the draw-off tap.Ensure that the lateral xing screws for the cover are always accessible.The appliance is only suitable for undersink installation (water connections at the top). DANGER ElectrocutionProtection rating IP25 is only ensured if the appli-ance back panel is tted. » Always t the appliance back panel.

10.3 Connecting the power supply

DANGER ElectrocutionCarry out all electrical connection and installation work in accordance with regulations. DANGER ElectrocutionEnsure that the appliance is earthed.Ensure the appliance can be separated from the power supply by an isolator that disconnects all poles with at least 3 mm contact separation. DANGER ElectrocutionThe appliances are delivered with a power cable

MTD 350 with plug). Connection to a permanent power supply is pos-sible, provided the xed cable has a cross-section that is at least equal to that of the standard power cable of the appliance. A maximum cross-section of 3 x 6 mm² may be used.

Material lossesWhen making the connection to a standard safety socket (in the case of a power cable with plug), en-sure that the socket is freely accessible after the appliance has been installed.

Material lossesTake note of the type plate. The specied voltage must match the mains voltage. » Connect the power cable as shown in the wiring dia-gram (see chapter "Specication / Wiring diagram").34 Installation - for contractors

11.1 Initial start-up

26_02_05_0087 » Fill the appliance by running the tap several times until the pipework and appliance are free of air. » Carry out a tightness check. » Insert the power cable plug, if present, into the standard safety socket or set the fuse/MCB. » Check the function of the appliance.

11.2 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.

11.3 Recommissioning

Material lossesFollowing an interruption of the water supply, recom-mission the appliance by carrying out the following steps, in order to prevent irreparable damage to the bare wire heating system. » Isolate the appliance from the power supply. Pull the power cable plug, if present, from the socket, or re-move the fuse/reset the MCB. » See chapter "Initial start-up".

» Isolate the appliance from the power supply by means of the fuse/MCB in your fuse box or by pulling the power cable plug from the socket. » Drain the appliance (see chapter "Maintenance").35 Installation - for contractors

Problem Cause Remedy The appliance will not start despite the DHW valve being fully open. The aerator in the tap is scaled up or dirty. Clean and/or descale the aerator or replace the special aerator.

The sieve in the cold water line is blocked. Clean the sieve after shutting off the cold water inlet line.

The heater is faulty.

Check the resistance of the heating system and replace the appli- ance if required.

The safety pressure limiter has responded.

Remedy the cause of the fault. Isolate the appliance from the power supply and de- pressurise the water line. Activate the safe- ty pressure limiter. Activating the safety pressure limiter

DANGER Electrocution Before any work on the appliance, disconnect all poles from the power supply. Draining the appliance DANGER Scalding Hot water may escape during the draining process. If the appliance needs to be drained for maintenance or to protect the whole installation when there is a risk of frost, proceed as follows: » Close the shut-off valve in the cold water inlet line. » Open the draw-off valve. » Undo the water connections on the appliance. Cleaning the strainer You can clean the tted strainer after removing the cold water supply pipe. 26_02_05_0065_ Checking the earth conductor » Check the earth conductor (in Germany e.g. BGV A3) on the earth conductor contact of the power cable and on the appliance connector. Appliance storage » Store the dismantled appliance in a room free from the risk of frost, as water residues remaining inside the appliance can freeze and cause damage. Replacing the power cable for the MTD 570 » If replacing the cable for the MTD 570, use a power cable with 4 mm² cross-section.37 Installation - for contractors
