Protective equipment
Several different protective devices are built into
the hob to protect your cooking utensils and the
electronics. When the hob is built in correctly the
protective equipment will react seldom or never.
Detection protection
The cooking zone reacts only if there is a suitable
pan standing on it. If there is only a spoon or a
fork on the cooking zone it will not switch on. The
lights will continue to flash. The appliance will
switch itself off also if two pans touch each other
or if one pan comes in contact with a wall.
Ensure thus that the pans are "free".
Ventilation protection
The electronics must be cooled. Cool air will be
drawn in from behind the kitchen cabinet and
blown out from the front below the work top. The
appliance can therefore only function when
sufficient air can circulate. If the ventilation flow
is insufficient the hob will not switch on.
Overheating protection
Three protective devices are built into the hob to
protect it against overheating.
The first device protects the electronics. If the
electronics temperature rises too high, this device
will act. The hob will be switched off. The fan will
continue to run to cool the hob. F7 will appear in
the display. Press any button and the message
will disappear. Switch on the hob again and
select a lower power.
The second device protects your pans. This it
does by checking the temperature of the ceramic
plate. It is important for this device that the
bottom of the pan is flat. If the temperature is too
high the hob automatically switches to a lower
power. If this device should be defective F1 and
F2 (front zones) or F3 and F4 (rear zones) will
appear in the display. If the fault messages F1, F2,
F3, F4, F5, F6 or F8 should appear in the display
telephone the service department.
The third device protects against a pan on fire. If
you put a pan that is empty or contains very little
on the hob it will measure the heating process
and find that it is heating too quickly and switch
automatically to a lower power. This lower power
will not be visible in the display. As soon as the
plate has reached the maximum temperature the
hob will be switched off (the second device will
have then come into operation).
Installation
This appliance should only be installed by a
qualified installation engineer!
Damage caused by improper installation or
connection is not covered by the guarantee.
Safety instructions
For the appliance to operate properly, make sure
that:
there is adequate ventilation both under and
behind the kitchen unit, and under the worktop
at the front (see Ventilation);
the power cable is hanging free and not
trapped by a drawer;
the worktop is between 3.2 cm and 4 cm thick;
the worktop is level.
If the hob is to be built in any nearer than 4 cm
from an adjacent wall or kitchen cabinet,
either to the back or side of the appliance, the
wall or cabinet should be lined with a heat
resistant material. Whilst the hob itself will not
generate heat a saucepan or frying pan placed
on the appliance could possibly generate
temperatures high enough to damage some
materials.
Electrical connection
230 V AC - 50 HZ - 5600 W
The appliance should always be earthed. Use
good quality cable for connecting e.g. H05RRF, 1,5
or 2,5 mm
2
, with 3 or 5 cores, depending on the
regulations. With following colour code:
– brown = phase L
– blue = N
– green/yellow = earth (
)
Depending upon the wiring diagram, you can use
the black cores for neutral or a phase.
The cable must have a plug suitable for a nominal
load of at least 15 A.

There is a label showing the wiring diagrams on
the underside of the appliance. The cable
connectors can be reached by opening the cover
on the underside with the aid of a screwdriver
(see Figure 9).
You can make the cross connections needed
using the jumpers on the terminal block. Do not
forget to secure the cable with the cable clamp.
Replace the cover once you have fixed the cable.
If you want to make a fixed connection, ensure
that a multi-pole switch with a distance between
contacts of 3 mm is installed in the supply cable.
