manual abstract
¦ The continuous-flow heater may only be connected and put into operation by a qualified professional. ¦ Never open the appliance without disconnecting the power supply beforehand. ¦ The statutory regulations of the respective country, as well as those of the local electricity and water suppliers, must be adhered to. ¦ The continuous-flow heater is a Class I appliance and must be connected to the protective earth. ¦ The appliance must be permanently connected to installed pipes. The conductor cross-section must comply with the installed appliance power. ¦ Caution: Earthed water pipes may give the appearance of a connected protective earth. ¦ 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 (pressurized) operation. ¦ The tap and outlet fittings must be approved for operation with closed (pressurized) continuous-flow heater systems. ¦ The continuous-flow heater can be operated 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 continuous-flow heater is only suitable for connection to DVGW (German Technical and Scientific Association for Gas and Water) approved plastic pipes. ¦ The continuous-flow heater may only be installed in a frost-free room. ¦ 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 required 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. Installation I. Unpacking/Removing the cover ¦ Unpack the appliance and check for transport-related damage. ¦ Please dispose of the packaging, and if applicable, the old appliance in an environmentally-friendly manner. 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 (connection 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 mounted on the wall. Attach it if necessary on the lower adjustable screws. ¦ The distance to the wall is variable. You can compensate for any unevenness of the wall's surface. ¦ The grommet must tightly surround the connection cable. If it is damaged during mounting, the openings must be provided with watertight sealing. IV. Water connection ¦ The continuous-flow heater must be vented. The warm water tap must be opened and the appliance must be flushed out thoroughly for 1 minute with at least 6 litres of water. V. Electrical connection/Mounting ¦ 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. Set the power using the power selector switch before connecting the wires to the mains connection terminal: ¦ Set DE 1113415 to 11 kW (down) or 13 kW (up). ¦ Set DE 1821415 and DE 4151821 to 18 kW (down) or 21 kW (up). ¦ Set DE 2427415 or DE 4152427 to 24 kW (down) or 27 kW (up). The set power must be marked on the ratings plate. ¦ Now screw the wires tightly into the mains connection terminal. 8 en VI. Startup/additional information B The device is compliant to IEC 61000-3-12. First start-up ¦ Switch on the fuses. ¦ Setting the temperature. ¦ Starts rinsing: Open the warm water tap and allow water to flow for at least 1 minute (flow-rate at least 6 litres per 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. ¦ Remove the flow-rate limiter (see Fig. A) with low water pressure. ¦ Explain the operation of the continuous-flow heater to the user. A If the continuous-flow heater does not have sufficient water flow due to low water line pressure in your domestic plumbing system, remove the flow-rate limiter. Technical dat a CD Priority circuit for the combination with electrical storage heaters: For operation with a priority circuit, a special load shedding relay BZ 45L20 (special accessory) is required. Other existing load shedding relays, with the exception of electronic load shedding relays, may malfunction. The control electronics must be coded when operated with a load shedding relay.
