Congratulations on purchasing this Siemens appliance. You have acquired a top-quality product, which will give you a lot of enjoyment.Please read this installation and operating instruction manual carefully, then act accordingly! Store for future reference. Installation instructions Install the continuous-flow heater as described in the illustrated section. Observe the instructions in the text.The illustrations can be found in the centre of the instruction manual. Installation

Unpacking/removing the cover ■ Unpack the appliance and check for transport damage. ■ Dispose of the packaging and, where applicable, the old appliance, in an environmentally conscious manner. II. Preparation for installation Important: Only use the enclosed installation set. ■ Shut off water supply. The electrical connection (connec- tion cable) must be disconnected from the power supply. Unscrew the fuse or switch off the circuit breaker. III. Wall mounting ■ The continuous-flow heater must be fitted securely to the wall. If required, secure the appliance using the lower adjusting screws. ■ The distance from the wall is variable. This allows you to compensate for any unevenness in the wall surface. ■ The sleeve must fit tightly round the connection cable. If the sleeve is damaged during installation, the holes must be sealed water-tight. IV. Water connection ■ The continuous-flow heater must be vented. Open the warm water tap fully and flush out the appliance thorough-ly for 1 minute. ■ The flow-rate limiter must be installed in the old water regulating valve.

Electrical connection ■ The electrical supply terminal can be fitted at the top or bottom. The sheath of the connection cable must extend for at least 40 mm into the appliance.Installation note ■ The installation of non plug-in ready appliances must be undertaken by the respective utility operator or by a quali-fied specialist company, who can also assist you when you are requesting the approval of the utility company for installation of the appliance. VI. Startup The device is compliant to IEC 61000-3-12. ■ At low water pipe pressure, check whether the II setting switches on even when water is drawn from several cold-water taps simultaneously. If not, remove the flow limiter (refer to additional information A). ■ Instruct the user with regard to the operation of the con- tinuous-flow heater. A B Additional information ■ If the water pressure of the interior system is low, do not operate the continuous-flow heater at full power, but re-move the flow limiter (Fig. A, 3.). ■ Priority circuit for the combined operation of electric stor-age heaters (Fig. B).10

Operating instructions Please read and observe the detailed safety instructions at the start of these instructions! ■ Important: The appliance may never be exposed to frost! Risk of electric shock!Switch off the mains voltage supply immediately if a fault occurs. ■ Immediately shut off the cold water supply to the appli- ance should it leak. Getting to know your appliance The continuous-flow heater heats the water as it flows through the appliance. The appliance only consumes power during this period.

Operating elements The continuous-flow heater has two heat settings:e Economy setting – two thirds powerII Intensive setting – full powerThe e setting is ideal for:Wash basinShowerBidetThe II setting is used in combination with a thermostatically-controlled premixer, for high temperatures or for large vol-umes of water, e. g. for:DishwashingCleaningBath tub Operating the appliance

Turn on the hot-water tap The continuous-flow heater switches on and heats the water when the hot-water tap is turned on (Fig. E, 1.). It switches off again when the tap is turned off.Notes (not applicable for DH12...): When the water tap is turned on only slightly, the continuous-flow heater will oper- ate at half power in both of the preselected settings (e, II). When the water tap is turned on fully, the appliance will oper-ate at full, preselected power.

Increasing the water temperature Slightly close the hot-water tap (Fig. E, 2.).

Decreasing the water temperature Turn on the cold-water tap (Fig. E, 3.). Startup after a water cutoff ■ Disconnect the appliance from the mains supply (remove the fuses in the fusebox). ■ Turn on the hot-water tap until the air is purged from the pipe. ■ Reinstall the fuses.The appliance is ready for operation. Saving energy Use the “e” setting whenever possible.For wash basins: Open the corner valve to such an extent that only the lower heat setting switches on. Winter operation Note: It is possible in winter that the supply temperature of the water is reduced and the required outlet temperature is no longer achieved. ■ In order to compensate for this temperature reduction, please reduce the water quantity on the tap until the re-quired water temperature is achieved. Cleaning Simply wipe the appliance with a damp cloth. Do not use acidic or abrasive cleaning materials.Notes: It is normally not necessary to descale the appliance. However, extremely hard water and the frequent flows of very hot water can cause the appliance to scale up. In this case please contact our after-sales service. After-sales service If you call the after-sales service for assistance, please specify the E no. and FD no. of your appliance. These numbers are found on the inside of the swing-out con-trol panel of the continuous-flow heater.12

A fault, what to do? Attention! Repairs must only be carried out by an authorised technician. Improper repairs can lead to risk of serious injury to the user. If your appliance does not operate as required, it is often due to a very minor problem. Please check whether you can remedy the fault yourself by using the following guidelines. You will save yourself the costs of an unnecessary visit by customer service personnel. Fault Cause Solution Who Water flow-rate is too low. The appliance does not switch on. The filter in either the water tap or the showerhead is clogged. Remove the filter and either clean it or descale it. Customer The filter in the corner valve is clogged. Get a servicing expert to clean the filter. Servicing expert The corner valve is clogged. Turn on the hot-water tap fully and open and close the corner valve several times. Then clean the filter in the water tap. Customer The water is not sufficiently warm. The fuse in the house electrical installation has tripped/blown. Check the fuse in the fusebox. Customer The appliance‘s automatic circuit breaker has been tripped. Get the appliance‘s automatic circuit breaker checked by an electrician. Check the permissible supply temperature. Servicing expert The power limit has been reached. Water flow-rate is too high and/or the cold water supply temperature is too low. Reduce the flow-rate on the tap. Customer By a qualified professional: use the corner valve to regulate the flow-rate. Check the flow-rate limiter or replace it with a smaller one. Servicing expert The second stage in the appliance does not switch on (the audible “clicking” is missing). Remove the filter in the tap and either clean it or descale it. Customer Clean the filter in the corner valve (Fig. A, 4.). Servicing expert The continuous-flow heater switches off during the drawing-off of water, result- ing in a reduction in the water temperature: Swelling seal in the warm water tap A non-swelling sealing material must be used in the warm water tap. Customer Winter operation: The desired water tempera- ture leaving the tap is no longer reached. The supply temperature has reduced. Reduce the water flow on the taps until the desired water temperature is reached. Customer If the fault could not be eliminated, please call customer service.
