Maintenance and cleaning
Do not clean the hob if the glass is hot : risk of burn. Remove light marks with a damp cloth with washing up liquid diluted in a little water. Then rinse with cold water and dry the surface thoroughly. Highly corrosive or abrasive detergents and cleaning equipment likely to cause scratches must be absolutely avoided. Ensure that the bottom of pans is dry and clean. Ensure that there are no grains of dust on your ceramic hob or on the bottom of the pan. Sliding rough saucepans will scratch the surface. Spillages of sugar, jam, jelly, etc. must be removed immediately. You will thus prevent the surface being damaged. Trouble shooting Problem Possible cause Solution The hob or the cooking zone doesn't start-up The hob is badly connected on the electrical network The protection fuse cut-off The looking function is activated The sensitive keys are covered of grease or water An object is put on a key The symbol [F] displays You cannot use this cooking zone anymore Call the After-sales Service The symbol [E] displays The electronic system is defective One or all cooking zones cut-off The safety system functioned Disconnect and replug the hob Call the After-sales Service The automatic cooking system <« go and stop >> doesn't start-up You forgot to cut-off the cooking zone for a long time One or more sentive keys are covered The pan is empty and its bottom overheated The symbol [L] displays The cooking zone is still hot [H] The highest power level is set [9] The cooking level was engaged with [-] Refer to the control panel locking chapter. Electrical connection • The installation of this appliance and the connection to the electrical network should be entrus- ted only to an electrician perfectly to the fact of the normative regulations and which respects them scrupulously. • Protection against the parts under tension must be ensured after the builting-in. • The data of connection necessary are on the stickers place on the hob casing near the con- nection box. • The connection to the main must be made using an earthed plug or via an omnipolar circuit breaking device with a contact opening of at least 3 mm. • The electrical circuit must be separated from the network by adapted devices, for example : circuit breakers, fuses or contactors. Caution! This appliance has only to be connected to a network 230 V~ 50 Hz. Connect always the earth wire. Respect the connection diagram. The connection box is located underneath at the back of the hob casing. To open the cover use a medium screwdriver. Place it in the slits and open the cover. Mains Connection Cable diameter Protection calibre 230V~1P+N 50Hz 1 Phase + N 3 x 2.5 mm² 25 A * 400V~2P+N 50Hz 2 Phases + N 4 x 1.5 mm² 16 A * 230V~2P+2N 50 Hz 2 Phases + 2N 5 x 1,5 mm² 16 A * (*) calculated with the simultaneous factor following standard TN 60 335-2-6/1990. Connection of the hob For the various kinds of connection, use the brass bridges which are in the box next the terminal 1 phase 230V~1F+N (not for the Netherlands!): Place a bridge between 1 and 2. Attach the earthing to the “earth” terminal clamp, the neutral N to terminal clamp 4 or 5, and phase L to terminal clamp 1 or 2. 2 phases 400V~2F+N: Attach the earth to the terminat “earth”, the neutral N to terminal 4, the Phase L1 to the termi- nals 1 and the Phase L2 to the terminal 2. 2 phases 230V~2F+2N: Place a bridge between 2 and 3. Connect the earthing to the “earth” terminal clamp, neutral N1 to terminal clamp 4, neutral N2 to terminal clamp 5, phase L1 to clamp 1 and phase L2 to clamp 2. Caution! ensure that you : correctly attach the wires and the bridges. Tighten the screws properly. Before making the connection, we strongly advise you to locate the phase(s), neutral and earth on the mains. If you have any doubts, call your electrician. Note: the bridges between terminals 4-5 and between terminals 1-2 were installed during the factory check. We cannot be held responsible for any incident resulting from incorrect connection or which could arise from the use of an ap- pliance which has not been earthed or has been equipped with a faulty earth connection.
