Initial commissioning Please adhere the extra appliance data plate (supplied) in the space provided in the "After sales service" section of this manual. Remove any protective foil and stickers. Cleaning the cooktop for the first time Before first use, wipe down the appliance with a damp cloth and dry it. Turning on the cooktop for the first time Metal components are protected by a conditioning agent. Smells and vapor may occur when the appliance is used for the first time.
Induction How it works An induction coil is located under each cooking zone. When a zone is turned on, this coil creates a magnetic field that impacts directly on the base of the pan and heats it up. The cooking zone itself is heated up indirectly by the heat given off by the pan. An induction cooking zone only works when a ferromagnetic pan is placed on it (see "Cookware"). The induction cooking zone automatically recognizes the size of the pan.
Induction Noises When you use an induction cooking zone, the following noises may occur, depending on the type and shape of the cookware bottom: On the higher power settings, it might buzz. This will decrease or cease altogether when the power setting is reduced. Cookware with bottoms made of different materials (e.g. sandwich bottoms) may produce a crackling noise.
Induction Cookware Suitable cookware is made of: – Stainless steel with a magnetizable bottom – Enamel-coated steel – Cast iron Unsuitable cookware is made of: – Stainless steel with a non-magnetizable bottom – Aluminum or copper – Glass, ceramics, earthenware, stoneware To test whether a pot or pan is suitable for use on an induction cooktop, hold a magnet to the base of the pan. If the magnet sticks, the pan is suitable.
Energy saving tips – Use a lid whenever possible to minimize heat loss. – For small quantities, select a small pan. A small pan on a small burner uses less energy than a large, only partially filled pan on a large burner. – Cook with as little water as possible. – Once food has come to the boil or the pan is hot for frying, reduce the heat to a lower power setting.
Power setting ranges The cooktop is programmed with 9 power levels at the factory. If you wish to finetune a setting, you can extend the power setting range to 17 power levels (see "Programming").
Operation Basic operation The glass ceramic cooking zone is equipped with electronic sensor buttons that react to finger contact. During activation, the On/Off sensor button must be pressed somewhat longer than the other buttons for safety reasons. Each reaction of the buttons is acknowledged with an acoustic signal. When the cooktop is turned off, only the pressed symbols for the On/Off and System Lock/Safety Lock sensor buttons are visible.
Operation Fire hazard! Residual heat indicator Do not leave the cooktop unattended during operation! Please note that the heat-up time for induction cooktops is shorter than for conventional cooktops. When a cooking zone is hot, the residual heat indicator and the sensor button light up on the control scale after deactivation. Turning on To turn on the cooktop, briefly touch the sensor button. All of the sensor buttons will light up.
Operation Setting the power level - expanded setting range Tap the control scale between the sensor buttons. The sensor buttons in front of and behind the medium level light up brighter than the other buttons. Example: If you have selected power setting 7., the numbers 7 and 8 will be brighter than the other numbers. PowerFlex cooking zone You can combine the PowerFlex cooking zones into one large PowerFlex cooking zone (see the "Overview – Cooking zone" chapter).

Operation TwinBooster / Booster The cooking zones are equipped with a booster or TwinBooster (see "Overview – Cooking zone"). You can use the booster for a maximum of two cooking zones at the same time. When activated, the power is boosted for a maximum of 15 minutes so that large quantities can be heated quickly, e.g., pasta water.
Operation During the booster time, the sensor button and all of the sensor buttons on the control scale are at brightness level 2. Activating the booster Tap the sensor button on the control scale for the desired cooking zone. Select a power level if required. Turning the booster/TwinBooster On/ Off Tap the sensor button: – once (booster) – until the indicator lights go off (TwinBooster) or select a different power level. Tap the sensor button.
Operation Keep warm function The keep warm function is for keeping food warm that has just been cooked, i.e., food that is still hot. It is not for reheating cold food. If the keep warm function has been activated, the cooking zone will turn off automatically after a maximum of 2 hours. – Only use pans for keeping food warm. Cover the pan with a lid. – It is not necessary to stir the food while it is being kept warm. – Nutrients are lost when food is cooked, and continue to diminish when food is kept warm.
Timer The cooktop has to be turned on if you wish to use the timer. You can set a time between 1 minute () and 9 hours (.). The timer can be used for two different functions: Timer Setting the minutes Example: You want to set a time of 15 minutes. Turn the cooktop on. – For setting the timer Tap the sensor button. – For turning off a cooking zone automatically. The sensor button flashes. appears in the timer display, and the right flashes.
Timer Setting the hours Changing the timer To set full hours, tap the respective sensor button on the control scale. To set the half hours, tap the space between 2 sensor buttons on the control scale. Tap the sensor button. Example: You want to set a time of 2 hours and 30 minutes. Tap the sensor button. Turn the cooktop on. Tap the sensor button. The sensor button flashes. appears in the timer display, and the right flashes.
Timer Turning a cooking zone off automatically You can set a time after which the cooking zone will turn off automatically. This function can be used on all zones at the same time. If the programmed time is longer than the maximum time allowed, the safety shut-off function will turn off the cooking zone automatically when the maximum time has elapsed (see "safety shut-off"). If you want to set another cooking zone to turn off automatically, follow the same steps as described above.
Timer Using both timer functions at the same time The timer and automatic turn-off functions can be used at the same time. If you would like to call the other remaining times so that they appear in the display: Tap the sensor button until: If you have programmed in one or more turn-off times, and would like to use the timer as well: – The indicator light for the desired cooking zone starts flashing (automatic turn-off).
Additional functions Stop & Go function When activated, the Stop & Go reduces the power of all cooking zones in use to power level 1. The power levels of the zones and setting of the timer cannot be changed and the cooktop can only be turned off. A set timer and booster time continue to run. The Auto Heat-up time and set times for automatic turn-off are stopped.
Safety features System lock / Safety lock The system lock and safety lock are deactivated if there is a power outage. Three-finger control is the default setting. You can change the default to one-finger control (see "Programming"). Your cooktop is equipped with a safety lock to prevent the cooktop and the cooking zones being turned on or any settings being altered. The system lock is activated when the cooktop is turned off.
Safety features Safety shut-off Safety shut-off with an overlong cooking time The safety shut-off is triggered automatically if a cooking zone is heated for an unusually long period of time. This time depends on the power level selected. If it has been exceeded, the cooking zone turns off and the residual heat indicator appears. If you turn the cooking zone on and off again, it is ready for operation again.
Safety features Overheat protection Overheating can be caused by: All the induction coils and the cooling elements for the electronics are equipped with an overheating protection mechanism. To prevent the induction coils and cooling elements from overheating, the overheating protection mechanism works on the affected cooking zone or on the entire cooktop in the following ways: – Heating empty cookware Inductive coils – Any booster function in operation will be turned off.
Cleaning and care Burn hazard! Unsuitable cleaning agents The burners must be turned off and allowed to cool completely. To prevent damage to surfaces, avoid the following while cleaning: Risk of injury! The steam from a steam cleaner could reach electrical components and cause a short circuit. Do not use a steam cleaner to clean the cooktop. All cooktop surfaces can become discolored or damaged if unsuitable cleaning agents are used. The outer surfaces of the cooktop are susceptible to scratching.
Cleaning and care Cleaning the glass ceramic surface Risk of damage from sharp and pointed objects! Do not clean the area between the glass-ceramic surface and the frame or the frame and the counter with sharp objects. When cleaning with liquid dish soap, not all contaminants and residues are removed. An invisible film forms, which causes discoloration of the ceramic. This discoloration cannot be removed. Clean the glass ceramic surface regularly with a suitable ceramic cooktop cleaning agent.
