Damaged appliances must not be installed. Do not use the hob if the ceramic glass is damaged: - switch off the cooking zones, - disconnect from the electricity supply. A special electronically controlled safety--switch-off makes sure that all cooking zones are switched off automatically after a defined time, in case there will be no variation of settings. D D Safety when cleaning D D Ensure that all heating zones are switched off while cleaning the hob. For safety reasons do not clean the appliance with a steam jet or high pressure cleaner. How to avoid damaging your appliance D D Do not use the hob surface as a working surface or for storage. Do not use the cooking zones with empty pans or without pans. This could cause damage to the pans or the hob. Ceramic glass is insensitive to temperature shock and very robust, however, it is not unbreakable. Hard and sharp objects, in particular, can damage the cooking surface if they fall on it. Do not use cast iron pots or pans with damaged bases that are rough or burred. Scratching may occur when the lids are slid. Do not place any pans on the hob frame. Scratching may occur or the paint damaged. Ensure that liquids containing acids, e. vinegar, lemon limescale removing agents do not come into contact with the hob frame, otherwise matt spots will appear. If sugar or a dish containing sugar comes into contact with a hot cooking zone and then melts, remove the soiling immediately whilst still warm, using a glass scraper. If it cools, damage to the surface may occur. Keep all items and materials that melt away from the ceramic glass surface, e. plastics, aluminium foil or oven foils. If something of this nature should melt onto the ceramic glass surface, it must be removed immediately using a glass scraper.
