Environmental protection and saving energy
Disposing of packaging
The packaging materials are environmentally compatible and can be recycled.
Sort the individual components by type and dispose of them separately.
Saving energy
If you follow these instructions, your appliance will use less energy. Select the cooking zone to match the size of your pan. Center the cookware on the hob. Use cookware whose base diameter is the same diameter as the hotplate.
Tip: Cookware manufacturers often give the upper diameter of the saucepan. It is often larger than the base diameter.
- Unsuitable cookware or incompletely covered cooking zones consume a lot of energy.
Cover saucepans with suitable lids. - Cooking without a lid consumes considerably more energy.
Lift lids as infrequently as possible. - When you lift the lid, a lot of energy escapes.
Use a glass lid. - You can see into the pan through a glass lid without having to lift it.
Use pots and pans with flat bases. - Uneven bases increase energy consumption.
Use cookware that is suitable for the quantity of food. - Large items of cookware containing little food need more energy to heat up.
Cook with only a little water. - The more water that is contained in the cookware, the more energy is required to heat it up.
Turn down to a lower power level early on. - If you use an ongoing power level that is too high, you will waste energy.
Take advantage of the hob’s residual heat. Withlonger cooking times switch off the hotplate5-10 minutes before the end of cooking. - Unused residual heat increases energy consumption.
Product Information according (EU) 66/2014 can be found on the attached appliance pass and online on the product page for your appliance.
Familiarising yourself with your appliance
The instruction manual is the same for various different hobs. You can find the hob dimensions in the overview of models.
Hotplates
You can find an overview of the different activations of the hotplates here.
Notes
- Dark areas in the glow pattern of the hotplate are part of the technical design. They do not affect the functionality of the hotplate.
- The hotplate regulates the temperature by switching the heat on and off. The heat may also switch on and off when at the highest setting.
- This protects easily damaged components from overheating.
- The appliance is protected against electrical overload.
Hotplate display and residual heat indicator
The hob has a hotplate display and a residual heat indicator. The display lights up when a hotplate is warm.
Display
Hotplate display: Lights up during operation, shortly after switching on.
