[. . . ] power limit, the instantaneous water heater supplies the set hot water temperature regardless of the water flowrate selected. If the hot water temperature is not attained when the hot water valve is fully opened, more water flows than can be heated by the appliance power. In this case, the hot water tap must be slightly closed. The built-in automatic flowlimiter limits the flow in such a way that also with fully opened warm water outlet valve and low cold water inlet temperatures a shower-fair outlet temperature (approx. [. . . ] Never use any abrasive, scouring, and solvent-containing detergents. The instantaneous water heater generally needs no maintenance. Regular inspection of the appliance by a trained engineer will ensure its operational reliability and prolong its service life. Scale deposits in the outlet of fittings reduce the water flowrate. The air bubblers of the fittings or hand shower head must therefore be cleaned from time to time. 4 Important instructions for the installer General The instantaneous water heater is manufactured and tested in conformity with the valid IEC specifications and DIN standards. The appliance complies with the Appliance Safety Act. The indications given on the rating plate, the technical connection specifications of the electricity and water companies in the geographical area concerned, and VDE 0100 and DIN 1988 must be observed when the appliance is being installed. Before all work on the equipment the mains voltage supply must be interrupted. The specific resistance of the water at the installation site should not be less than 1100 cm. This appliance complies with the following EC Directives: - the "Low-Voltage Directive" 72/23/EEC of 19. 02. 1973, including Amendment Directive 93/68/EEC - the"Electromagnetic Compatibility" Directive 89/336/EEC of 03. 05. 1989 including Amendment Directive 92/31/EEC Appliance constitution 1 2 3 4 5 16 6 7 5a 15 8 9 10 11 12 14 4a 13 1 = Back wall 2 = Thermal sensor 3 = Quick fastener for appliance mounting 4 = Upper cable bushing 4a = Lower cable bushing 5 = Upper mains connection terminal (factory-prefitted) 5a = Lower mains connection terminal (transpose mains connection terminal) 6 = Flowrate sensor 7 = Safety temperature and pressure limiter 8 = Electronic module 9 = Temperature Display 10 = Temperature selector knob 11 = Flowrate limiter 12 = Strainer insert, connection for direct tapping fitting 13 = Cold water connection 14 = Hot water connection 15 = Thermostat 16 = Heating block 5 Technical data Model Type Nominal capacity Dimensions Width Height Depth Weight Nominal overpressure Protection class to VDE Protection type to VDE Test mark Water connection Electrical connection Nominal output kW 18 Liters IH E 18 LCD IH E 21 LCD unvented 0, 4 226 469 95 3, 9 1 (10) I IH E 24 LCD mm kg Mpa (bar) IP 25 (splash-water protected) See rating plate G 1/2 A 3 / PE ~ 380 V 21 > 1100 0. 04 (0, 4) l/min 0. 035 (0, 35) 3 Free from any mains retroactive effect to DIN EN 60555/VDE 0838 VDEW Approval ° C l/min < 70 (power engagement up to 45 °C) 8 9 10 0. 03 (0, 3) 24 Spec. The supporting sheet (1) enclosed with the fitting fixes the extension pipes in position and seals the housing openings. To ensure moisture protection, the supporting sheet must be fitted. 2 Fitting must be vertically seated and centrally under the appliance. Seal appliance connection to the wall, where necessary, with G 1/2 A blind plugs (2) (fitting accessory). If a cold water supply is made to the appliance, the shutoff adapter (3) should be replaced by an adapter with a wood screw (4) for fixing the fitting in place. 1 3 4 The following tapping fittings are suitable: D 169 - Special mixer tap with swivelling outlet D 159 - Special shower mixer tap D 149 - Special bath mixer tap with change-over tub/shower Important!After completion of the water installation, the appliance should be thoroughly flushed with cold water (open the hot water valve). The strainer insert may possibly need cleaning afterwards. 11 Cleaning the strainer insert If the water flowrate is reduced by dirt from the cold water line, the strainerinsert should be cleaned as follows: 1 3 2 Flow rate limiter - Shut off cold water on shutoff unit (1) - Loosen cap nut (2 ) using a spanner - Take out and clean strainer (3) - Re-assemble in reverse sequence - Open cold water on shutoff unit (1); check tightness 1 2 The flow rate limiter (2) is installed in the cold water connector (1) to allow a constant outlet temperature at high flow pressures of approx. (See table page 4 and 6) 12 Electrical connection The electrical connection should only ever be made after the water is connected!The appliance is only suitable for a fixed connection of 380 V 3 ~ (three-phase current) . The appliance must be connected to the protective conductor. Important note: The wiring must be arranged so that the appliance can be de-energised (disconnected from the electricity supply) before any intervention involving the fuses being unscrewed, the automatic safety devices being switched off, or similar measures being taken (isolating gap width of at least 3 mm). Mains connection lead The connection cable must project from the wall over an insulated length of at least 20 mm. 20 150 Mains connection on top max. 10 1 4 2 3 Electrical connection terminal (3) factory-prefitted. Slide flexible inlet bush (2) over connection cable, insert it through the back wall opening, and screw fixing strap under connection terminal (4). 13 Mains connection underneath (alternative) For this connection version, transpose the mains connection terminal 2 (1) from top to bottom. [. . . ] Note the terminal designation on the back wall, and do not cross the connection leads to 3 the safety temperature limiter. Carry out cable inlet opening (2), inlet bush (3), and bush fixing under the mains connection terminal as described above for mains connection. Moisture protection is only guaranteed with the inlet bush fitted in position. 1 Circuit diagram L1(R) L2(S) L3(T) PE Main connection terminal D Heating block Heizblock 4 W4 3 2 W3 1 W2 W1 5 K 4 L1 5 LCD Safetytemperature and pressure limiter S 12 LED 1 3 L2 L3 IN S2 2 Electronic Elektronik system 14 Temperature selector range limitation The maximum temperature able to be set can be limited to 40°C or 45°C.
