USER MANUAL DE2124407M SIEMENS

Intended Use This appliance is intended for domestic use and the household environment only. Safety information Please read this installation instruction manual carefully, then act accor dingly! Store for future reference. These installa- tion instructions must be included when transferring this appliance to a new owner. ■ The appliance may only be connected and put into operation by a qualified professional. ■ Install and operate the appliance as de- scribed in the text and illustrations. We do not accept liability for damage resulting from failure to heed these instructions. ■ The supplied water connection nozzles must be used and installed as shown in the supplementary sheets. Make sure that a check valve is installed in the cold water supply line. ■ This appliance is intended for use up to an altitude of 2000 m above sea level. ■ The appliance may only be installed and stored in a frost-free room (due to residual water). Risk of electric shock! Switch off the mains voltage supply immediately if a fault occurs. Disconnect the power supply before opening the appliance. Immediately shut off the cold water supply to the appliance should it leak. ■ The statutory regulations of the respective country, as well as those of the local electric- ity and water suppliers, must be adhered to. ■ The continuous-flow heater is a Class I appliance and must be connected to the protective earth. ■ Caution: Earthed water pipes may give the appearance of a connected protective earth. ■ The appliance must be permanently connected to installed pipes. The conduc- tor cross-section must comply with the installed appliance power. ■ To guarantee compliance to relevant safety regulations, an all-pole separator must be fitted during installation. The contact opening must be at least 3 mm. ■ The continuous-flow heater is only suitable for closed (pressurised) operation. ■ The tap and outlet fittings must be ap- proved for operation with closed (pressur- ised) continuous-flow heater systems. ■ The continuous-flow heater can be oper- ated with cold or pre-warmed water (for example, from a solar energy unit water supply). Observe the technical data and the special accessories for this purpose. ■ The water’s specific electrical resistivity must not be less than 1 300 Ωcm. Ask the local water utility company regarding the electrical resistivity of the water. ■ The continuous-flow heater is suitable for connection to DVGW-tested plastic pipes. ■ Disconnect the electrical connection cable from the supply and shut off the water supply before connecting the appliance! ■ Connect the water supply and then connect the electrical supply. ■ Only make the openings which are re- quired for installation on the rear of the appliance. If the appliance is reinstalled, the unused openings must be provided with watertight sealing. ■ Do not touch electrically live parts after installation. ■ Do not use aggressive or abrasive cleaning detergents! ■ Do not use a steam cleaner.7

Congratulations on purchasing this Siemens appliance. You have acquired a top-quality product, which will give you a lot of enjoyment. Installation instructions These installation instructions apply to various continuous-flow heater appliance models. Therefore the illustrations may deviate from the device you bought. ■ Install the appliance as shown in the illustrations. The illustrations can be found in the centre of the instruction manual. Observe the instructions in the text. Installation

Unpacking/Removing the cover ■ Unpack the appliance and check for transport damage. If any components are damaged, then do not connect the appliance. ■ Check that your appliance contains all components in-cluded in the scope of delivery: appliance, installation set with supplementary sheets, installation instructions, operating instructions. ■ Please dispose of the packaging and the old appliance in an environmentally-friendly manner. ■ When removing the cover from either a Type

Type appliance, please note the following: The Type cover is fastened by a central closure behind the service flap.The Type cover is attached by two screws located on the underside of the cover. II. Preparations for installation Important: Only use the supplied installation set. The supplied water connection nozzles must be installed! ■ 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. ■ Install the water connection nozzles according to the in- structions on the supplementary sheet. ■ The electrical connection cable can either be guided in at the top (X) or bottom (Y). ■ The rear panel must lie against the cold water connection nozzle in the position provided for such (Fig. II., 8.). III. Wall mounting ■ The grommet must tightly surround the connection cable. If it is damaged during mounting, the openings must be provided with watertight sealing. ■ The electrical supply terminal can be fitted at the top (X) or bottom (Y). The sheath of the connection cable must extend for at least 40 mm into the appliance. ■ The distance to the wall is variable. You can compensate for any unevenness of the wall’s surface. With a distance to the wall of 8–16 mm, insert the spacer and install the extender (Fig. III., 3. – 5.). ■ The appliance must be mounted securely on the wall. If nec- essary, attach it at the lower adjustable screws (Fig. III., 6.). IV. Water connection ■ Connect the water supply, then open the cold water supply. ■ The appliance must be vented. To do so, open the warm water tap fully and flush out the appliance thoroughly for 1 minute.

Electrical connection/Mounting ■ Only for appliances with power selector switches: Set the power using the power selector switch before connecting the wires to the mains connection terminal: Nominal output power left, reduced output right (Fig. V., 1.) and the set output marked on the ratings plate. ■ Screw the wires tightly into the mains connection terminal. ■ Switch on the safety limiter (Fig. V., 3.) ■ Install the cover – according to either Type

in- structions (Fig. V., 4. – 7.).Installation note ■ The installation of non plug-in ready appliances must be undertaken by the respective utility operator or by a qualified 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.First start-up ■ Switch on the fuses. ■ Setting the temperature. ■ Initial rinsing: Open the warm water tap fully and allow water to flow for at least 1 minute. Only then (for safety reasons) will the appliance begin to heat.Tip: Should the appliance not start because of a reduced flow-rate, remove the perlator, shower head or similar before start and repeat the process. ■ Explain the operation of the appliance to the user. VII. Additional information ■ If the appliance does not have sufficient water flow due to low water line pressure in your domestic plumbing sys-tem, remove the flow-rate limiter (Fig. VII., 1. – 3.). ■ Priority circuit for the combination with electrical storage heaters:For operation with a priority circuit, a special load shed-ding relay BZ 45L21 (special accessory) is required. Other existing load shedding relays, with the exception of elec-tronic load shedding relays, may malfunction (Fig. VII., Wiring diagram). ■ The control electronics must be coded when operated with a load shedding relay. Remove the keying nose on the electronics (Fig. VII., 4.).8

Solar heated Only for appliances that are suitable for solar heating systems: The appliance can only heat prewarmed water to a max. of 60 °C. If the cold water supply exceeds a temperature of 55 °C, the water will not be warmed any further. Important: The cold water supply temperature must not be higher than 55 °C! If the cold water supply exceeds a temperature of 60 °C, a circuit breaker will trigger and shut the appliance off. There- fore, the residential plumbing must be equipped with a ther- mostatic premixer (e. g. special accessory BZ 45T20) that will limit the cold water supply temperature to a max. of 55 °C by appropriately mixing in cold water. VIII.
