6 7 Appliance function The fully electronically controlled ELECTROLUX IH instant water heater is a pressurised appliance for the supply of one or more tapping points and heats the water as the latter continuously flows through it. A flowrate sensor switches on the heating at a flowrate of around 3 l/min and off again at around 2,5 l/min. The microprocessor controlled electronic system automatically adapts the heating power with regard for the inlet temperature, the temperature set on the temperature selector knob, and the water flowrate. The user thus has hot water available in an energy-saving system giving the exact temperature required without any time limitation whatever. The nominal operating pressure is 1 Mpa. If this value is exceeded, a pressure reducing valve should be provided in the household pipework. A safety valve is not necessary. The bare wire resistance heating system has a high efficiency. Its low weight and extremely low water content also make it suitable for hard, lime-containing water qualities. Safety temperature and pressure limiter In the event of a fault, the inbuilt safety temperature limiter isolates the appliance from the mains supply on all contacts. Before the appliance is switched back on, a trained engineer must ascertain and eliminate the cause of the fault (see page 17). Then carefully press in the contact rocker with a screwdriver until it audibly engages. Important! The safety temperature and pressure limiter should never be adapted or modified in any way! Important: Don't block up the contact rocker! Pressurepoint for screwdriver Installing the appliance The appliance should only ever be installed or stored in frost-free premises.

Prepare the appliance for assembly. Hood dismounting Press in the engagement lug on the underside of the appliance from above or from the front with a screwdriver and take off the hood. Pull out the connection lead of the temperature set-point pickup on the electronic system. The rotational range of the temperature selector knob can be limited (see page 15). Wall mounting Mark out wall-plug holes with the mounting template supplied, insert wall-plugs, and screw on fixing rail (1). Take out threaded pin (2) from the enclosed pack and screw in. Then prepare water connections, mount appliance on threaded pin and retaining rail, and fix by turning the quick fastener (3) one quarter revolution. 3 2 1 Water connection The water inlet temperature on the cold water connection should be max. 25°C. If plastic pipe systems are used as installation material, the pipe manufacturer must expressly and unreservedly confirm the applicability and quality of his pipes for this application. Concealed installation Insert connector with shutoff spindle (1) in cold water connection and double- nipple (2) in hot water outlet using hemp packing. The shutoff spindle must point downwards and the screw slot aligned in the flow direction of the water. The shutoff unit must not be used for throttling. The ELECTROLUX IH electronic can be operated with all pressure fittings suitable for instantaneous water heater. 10 11 Installation versions For fittings directly on the appliance, the bushing openings pre-embossed in the appliance hood must be cut out for the extension pipes of the fitting. 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. 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. 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. 1 2 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 12 - 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 Cleaning the strainer insert If the water flowrate is reduced by dirt from the cold water line, the strainerinsert should be cleaned as ...
