User manual AEG-ELECTROLUX IH21E

[. . . ] Recommendation for energy-saving operation: 40°C for washbasin, shower, and bath (knob tangibly engages). If this temperature is no longer needed, the appliance should be reset to the 40°C energy-saving level. IH ele ctroni c LCD CAUTION!When operating with prewarmed water (for example solar-energy plant) the outlet - temperature could be higher than prefixed in the LCDdisplay. [. . . ] 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. If this value is exceeded, a pressure reducing valve should be provided in the household pipework. 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 and pressure 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: Don't block up the contact rocker! Pressurepoint for screwdriver Important!The safety temperature and pressure limiter should never be adapted or modified in any way! 7 Installing the appliance The appliance should only ever be installed or stored in frost-free premises.

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 3 2 1 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. 9 Water connection The water inlet temperature on the cold water connection should be max. [. . . ] After initial startup, the user should be familiarised with operation of the appliance and the instructions for installation and use handed over for safekeeping. 16 Fault-finding (important instructions for the trained engineer) In the event of any fault, a check should first be made to ascertain whether the fuse and line protection switch have tripped. Fault - Heating system does not switch on - Hot water flowrate too low Cause - Appliance is not live - Strainer insert is clogged - Soiling or scaling of bubblers and shower heads - Defective heating system Remedy Check the voltage Clean strainer insert (see page 12) Dismantle and clean the bubblers and showers heads Inspection and repair only by the trained engineer - Inadmissibly high cold - Safety temperature and pressure limiter has water inlet temperature (over 70 °C) tripped - Inadmissibly high outlet temperature (over 70 °C) - Active fault indicator (LED) - System fault (see table on page 18) Appliance should not be operated with preheated water over 70 °C Inspection and repair only by the trained engineer Inspection and repair only by the trained engineer 17 Fault indications Fault pattern 1 Idicator LED 1 LED 2 No display Appliance does not work No display Hot water temperature too low Possible faults - Flowrate sensor not plugged Defective - L1 or L3 phase missing - L2 phase missing - Setpoint generator not fitted 2 FLASHES FLASHES long short Constant warm water temp. 37°C FLASHES FLASHES short long No correct degree rgulation FLASHES FLASHES long short No heat output FLASHES long OFF 3 - Temperature sensor not plugged / Defective 4 - Electronic defective - Outlet temperature > 70°C No heat output 5 FLASHES long ON - Inlet temperature > 45°C No heat output 6 OFF ON - Water flow > 20 l/min 18 Important for the expert The electronic controls the safety-function of the appliance. When a fault is noticed, the fault indicator (LED) blinks and the heating element is switched off. [. . . ]
