• Do not let hard or pointed objects fall onto the hob.
  Non heat-resistant materials will melt on heated hotplates.
• Do not use oven protective foil.
• Do not use aluminium foil or plastic containers.

2.1 Overview of the most common damage
Here you can find the most common types of damage and tips on how to avoid them.

Environmental protection and saving energy

3.1 Disposing of packaging
The packaging materials are environmentally compatible and can be recycled.

• Sort the individual components by type and dispose of them separately.

3.2 Saving energy
If you follow these instructions, your appliance will use less energy.
Select the cooking zone to match the size of your pan. Centre 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. With longer cooking times switch off the hotplate 5-10 minutes before the end of cooking.
• Unused residual heat increases energy consumption.
