5. Installation and operation
5.1 Functionality of induction cookers
With induction cooker, an electric voltage is applied on a conductor spool beneath the
glass. This creates magnetic fields, which directly heat up the bottom of the cookware
through a physical effect. This means saving time and energy, because contrary to
common hotplates, the cookware is heated up, not the heating element and the glass.
Due to the technical characteristics described above, another advantage is the very short
start-up cooking time.
In addition, the heat supply promptly adapts to changed settings and can be controlled in
small steps. The induction cooker reacts to changed settings just as fast as a gas stove,
as the energy reaches the pot immediately without having to heat up other materials first.
The induction technology combines this fast reaction with the basic advantage of
electricity, meaning being able to exactly adjust the heat supply.
Additional advantages of an induction cooker:
•As the cooking zone is only heated up indirectly via the bottom of the cookware, over
spilling food cannot stick and burn and there is hardly any danger of burns for the user.
The glass cooking zone is only heated up by the hot cookware.
•If the device is turned on and no dish for cooking is present or is removed, a repeating
audio signal will sound and the device will turn itself off after approx. 30 seconds.
•The device will detect if the appropriate cookware is placed on the heating plate.
If the cookware is not appropriate for induction hotplates, energy will not flow.
The device will turn off after approx. 30 seconds.
•When operating the cooking zone with empty cookware, a temperature sensor turns it
off automatically.
5.2 Safety instructions
WARNING! Electrical hazard!
Cable must not touch any hot parts.
•See that the cable does not touch any heat sources or sharp edges. Do not let the
cable dangle over the counter edge.
WARNING! Danger of burn!
During operation some parts of the device become very hot. Do not touch the hot
surface of the glass field. Please note: the induction cooker does not heat up itself
during cooking, but the temperature of the cookware heats up the cooking zone.

- 25 -
•Do not use the device in case it does not function properly, has been damaged or
dropped.
•Do not use any accessory or spare parts that have not been recommended by the
manufacturer. These can be dangerous for the user or lead to damages of the device
or personal injury, and further, the warranty expires.
•Do not lay the cable over carpets or heat insulations. Do not cover the cable.
Keep away the cable from operating range and do not dunk it into water.
•Do not move or tilt the device when in operation.
WARNING! Hazard via electrical current!
Do not insert any objects like wires or tools into the ventilation slots.
This may cause electric shocks.
•Do not move the induction cooker during cooking or with hot cookware on top of it.
•Do not use the device as a surface for storing various items. Do not leave such
objects as empty containers, etc. on it.
•We recommend not placing any metal kitchen utensils, cookware or pan lids, knives
or other metal objects on the cooking zone. These may heat up when the device is
turned on.
•Remember that items of jewelry such as rings, watches etc. can get hot if they are
close to the heating surface.
•The cooking zone's surface consists of temperature-resistant glass. In case of
damage, even if this concern only a small tear, disconnect the device from the power
supply immediately and contact the customer service.
•Do not place any magnetically objects like credit cards, cassettes etc. on the glass
surface while the device is in operation.
•On order to avoid overheating, do not place any aluminum foil or metal plates on the
device.
•Do not use any flammable, acidy or alkaline materials or substances near the device,
as this may reduce the service life of the device and lead to deflagration when the
device is turned on.
•Scientific tests have proven that induction cookers do not pose a risk. However,
persons with a pacemaker should keep a minimum distance of 60 cm to the device
while it is in operation.
WARNING! Hazard via electrical current!
The device can cause injuries due to improper installation!
Before installation the local power grid specification should be compared with
that of the device (see type label).Connect the device only in case of compliance!
Take note of the safety advice!
