16 INTRODUCTION
Principle of operation
The hotplate (2) contains a coil (1) that
generates an alternating magnetic field (3).
If a pan (4) with an iron base is placed above
the coil there will be a very rapidly changing
magnetic field in the pan bottom. This will
generate heat in the base of the pan.
Advantages
Cooking by induction has a number of
advantages:
■ Because of the high power of the induction
hob pans are brought to the boil very
quickly. Always keep this in mind and stay
close to the pan. Further cooking takes the
same time as with cooking by other means.
Potatoes are not cooked through faster, but
are brought to the boil faster. Induction
hobs are very suitable for the use of
pressure cookers. The cooker reaches its
working pressure very rapidly.
■ The cooking zone responds very quickly.
As soon as a cooking zone is switched off
no further heat will be added. The results
of the lower power are then immediately
visible.
■ The electronic control is accurate and
simple to set. The lowest setting (50 W) is
lower than for any other method of
cooking. Using the lowest setting you can
melt chocolate in a pan.
■ When the pan has been removed the
cooking zone cools very quickly. Cleaning
the hob is simple. Ceramic hobs with
heating elements have the disadvantage
that food can burn in. Induction hobs do not
have this disadvantage.
■ The heat is generated in the pan itself.
This reduces the heat losses to a minimum.
If you use a pan with a diameter smaller
than that of the cooking zone there are also
no losses. An incidental advantage is that
the pan handles do not get hot.

Precautions you must take
Induction cooking is extremely safe.
Because the heat is generated in the pan and
the ceramic plate will not get hotter than the
contents of the pan, the chance that you will
burn yourself on the hob is very slight.
However, there are, as with any other hob,
a number of matters of which you should be
aware.
■ This appliance should only be connected to
the mains supply by a qualified electrician.
■ The power supply must be disconnected
before the appliance is cleaned or
repaired. Remove the plug from the socket
or switch the electricity off at the mains.
■ This cooking appliance is designed for
domestic use. Do not use the appliance for
any purpose other than food preparation.
■ Remember the very short heating up time
at the higher settings. Always stay close to
the hob if you have a cooking zone on a
high setting (11 or 12).
■ Take care that the pan does not boil dry.
Damage caused by the use of unsuitable
pans and by pans boiling dry is excluded
from the warranty.
■ Never let an empty pan stand on a hotplate
that is switched on. While the hotplate is
protected and will switch itself off, the pan
will be extremely hot. The pan could be
damaged.
■ The ceramic plate is very strong but
certainly not unbreakable. When, for
example, a herb jar or a pointed object is
dropped onto it a break can be caused.
■ When a hob is broken or cracked it should
be used no longer. Immediately switch off
the hob, take the plug out of the socket and
telephone the service department.
■ When the induction hob is in use keep
objects that can be affected by magnetic
fields (credit cards, bank cards, diskettes,
watches and similar items) away from its
vicinity. We advise those who have
pacemakers to consult a heart specialist
first.
■ Aluminium foil should never be used as a
container for the preparation of dishes (for
example aluminium deep freeze
containers). Aluminium foil will melt and
stick to your hob and can never be
removed.
■ The cooking surface must not be used for
storage.
■ Do not place any metal objects such as
knives and forks on the cooking area. They
could become hot.
