the following notices to avoid dangers and damages:
Warning
►Do not leave the device unsupervised when it is in operation, so that you can intervene
quickly in the event of dangers.
5.1 Functioning and Advantages of Induction cooktops
With an induction cooktop the heat is not transferred by a heating element via the cooking
utensil to the food to be cooked, but rather the necessary heat is generated directly in the
cooking pot with the aid of induction currents.
An induction coil underneath the ceramic glass hob generates an alternating electromagnetic
field, which penetrates the ceramic glass hob and induces the heat-generating current in the
base of the cookware.
Advantages of the Induction Hob
•Energy-saving cooking due to direct energy transfer to the pot.
•Enhanced safety since energy is only transferred when a pot is placed on the hob.

14
•Energy transfer between the induction cooking zone and the base of the pot with high
degree of efficiency.
•Rapid heating.
•Low risk of burning, since the cooking surface is only heated by the base of the pot.
•Boiling over pot contents does not burn onto the hob.
•Rapid, fine-tuned control of the input power.
5.2 Instructions on Cookware
The cooking pot used for the induction cooking surface must be made of metal, have magnetic
characteristics and have a sufficient, flat bottom surface.
Here is how to decide if the pot is suitable:
Ensure that the pot bears an inscription stating its suitability for cooking
with induction current, or perform the following magnet test:
Place a magnet (e.g. a magnet from a magnetic board) close to the
base of your cooking pot. If it is strongly attracted then you can
use the cooking pot on the induction cooktop.
The table below serves as a guide to help you choose the correct cooking utensils:
Suitable Cookware Unsuitable Cookware
Cookware with magnetic bottom (ferreous). Pots made of copper, aluminium, heat-
resistant glass and other non-metallic pots
Enamel-coated steel pots with thick bases Pots made of stainless steel without a magnet
iron core
Cast-iron pots with enamel-coated bases Pots that do not sit flat on the hob
Pots made of stainless steel, multi-layered
steel, stainless steel ferrite steel or
aluminium with special base
Pots with a base diameter of
less than 5" or more than 9"
Please note
►Using the induction-compatible pots of some manufacturers can lead to the occurrence of
noises that are due to the design of these pots.
Attention
Please also adhere to the following instructions for using suitable cookware:
►Only use pots with an induction-compatible base.
►The maximum permissible weight of the pot plus its contents must not exceed 13 lbs.
►Be careful when using hollow-walled simmer pots. Pots of this type can boil dry unnoticed.
This leads to damage to the pot and hob.

15
5.3 Safety Instructions
Warning
►Do not leave the appliance unattended during operation, so that you can intervene quickly
in the event of danger.
►Do not move the appliance during operation or with hot cookware on the hot plate.
►Ensure that the cookware is properly centred on the hob. It must not be positioned on the
control panel or on the frame.
►In order to prevent overheating do not place any aluminium foil or metal panels on the
appliance surface.
►Do not touch the hot surface of the ceramic hob.
Although the induction cooktop itself does not produce any heat during the cooking process,
the temperature of the cookware does heat up the hob.
►Keep the hob and the underside of the pot clean and dry at all times. If liquid gets between
the base of the pot and the hob, this liquid can vaporise and the resulting pressure can
cause the pot to jump into the air, with a resulting risk of injury.
Please note
►Switch the appliance off after use. This avoids unnecessary use of energy, and ensures
your safety.
►If the appliance is unused for extended periods of time, we recommend that the appliance
be unplugged from the mains.

8 Disposal of the Old Device
Old electric and electronic devices frequently still contain valuable materials.
However, they also contain damaging substances, which were necessary for their
functionality and safety. If these were put in the non-recyclable waste or were
handled incorrectly, they could be detrimental to human health and the
environment. Therefore, do not put your old device into the non-recyclable waste
under any circumstances.
Please note
►Utilize the collection point, established in your town, to return and recycle old electric and
electronic devices. If necessary, contact your town hall, local refuse collection service or
your dealer for information.
►Ensure that your old device is stored safely away from children until it is taken away.
