and hand them to the next user if necessary.
The unit must only be used in the household and for its

intendedpurpose. It conforms with international safety
regulations and quality standards. The safetyfeatures
incorporated do not always cover all the possible risks
of accident.

Electrical safety

This appliance must only be installed by a quali­fied electrician. For reasons of electrical safety,
built--in appliances must only be installed into the
standard, matching mounting cabinet or worktop.

Only use the hob when it has been fully installed. This
willprevent you from coming into contact with current-­carrying parts.

Also follow theinformation given in the accompanying
Instructions for Use and for Installation

Damaged hobs with cracks or breakages in the glass
ceramic surface must not be connected to the mains.

For reasons of safety, repairs to the appliance, and in
particular to the current--carrying components, must
only be carried out by qualified electricians or trained
Customer Service technicians. Otherwise, considera­bledanger couldresult for theuser.Incase of malfunc­tion, contact our Customer Service department di­rectly.

If the glass--ceramic hob is to be used in the vicinity of
a radio, TV or other transmitting device, it must first be
clarified whether this could affect its operation.

The appliance is only disconnected from the mains
when the fuse is turned off or the mains connection is
interrupted.

Use and Operation

Prevent small children from touching the glass--cera­mic top when in use. As a rule, they should be kept
away from both the hob and from pots and pans.
Children can also burn themselves by pulling pans or
pots off the hob.

The cooking zones heat up quickly when they are tur­ned on. Only turn them on if you have placed a sauce­pan on the cooking area.

Exercise care when workingwith ahot hob, or hot pots
or pans. There is always a danger of being burned

The residual heat indicator integrated in the electro­nics tells you whether a cooking zone is still hot.

In case a pan/pot is left on the cooking zone the resi­dual heat indicator can switch off tough is the cooking
zone still hot from the pan with hot contents.

In the event of apower failure, all settings and displays
will be lost. Be careful, because hot cooking zones will
no longer be indicated by the residual heat indicator.

If you use asocket close to the hob, take care that the
cable of the appliance does not touch the hot surface
of the hob.

Do not store any temperature--sensitive or inflamma­ble materials (such as detergents, spray cans) in the
drawersor thecupboards underneaththe built--in hob.

The cooking surface must not be used as a storage or
working area.

Attention! Never look directly into the light from the
halogen cooking zone.

Never leave the hob unattended when working with
oils and fats, due to the danger of fire.

Never use plastic or aluminium foil dishes on the hob.
They melt at high temperatures, and can damage the
glass--ceramic plate.

Neithersugar (solidor liquid)nor plastic should beallo­wed to come into contact with the hot surface of the
hob.
Whentheplate cools down, cracks or breakagescould
occur in the glass--ceramic plate. If sugar or plastic
shouldaccidentallycome into contact with the hot hob,
the latter must not be switched off for any reason, but
the sugar or plastic remnants must be removed with a
scraper while still warm. Protect your hands from
burns.

To avoid scratching the surface of the glass--ceramic
hob,only use pots and panswith flat basesand without
rough edges.

The ceramic hob surface is resistant to extreme tem­peratures. Neither cold nor heat can harm it. Avoid
dropping anything on the hob. Point impacts, e.g. by
dropping a salt shaker,can causefissures and cracks.

A defective hob surface could allow food which has
boiled over to penetrate through the hob, and contact
the electrical parts.

If any cracks appear on the hob surface, the hob must
be switched off immediately. Disconnectthe appliance
from the mains and inform the service department.

147

Follow the Care and Cleaning instructions for the
glass--ceramic surface. We will accept no liability for
improper use.

After use, check that the appliance is switched off.

Cleaning

No heating element should be switched on while clea­ning. Ensure that the cooking areas have cooled down
sufficiently (wait until the residual heat lamp goes out)
so that there is no danger of burning.

Always keep the glass--ceramic surface clean.
For reasons of electrical safety, steam and high--pres-

sure cleaning devices must not be used for cleaning
the hob.

Disposal

Please dispose of packing material and any
old appliances according to the relevant re­gulations. Please observe national and re­gional regulations and the material designa­tion (material separation, waste collection,
material disposal points).

on.

The Cooking Zone

Ceramic cooking
surface

The cooking surface is made of ceramic glass. The
surfaceis pore--freeandalso insensitiveto rapidchan­ges in temperature. Pots can therefore be moved from
a hot to a cold zone.

When switching on the cooking zone there may be a
brief humming sound from the heaters. This is normal
and disappears when the cooking zone has warmed
up.

Keep all objects and materials which can melt
away from the cooking surface, e.g. plastics,
aluminium foil.

The right cooking utensils

Energy consumption

To save energy, you should . . .

-- use only cooking and frying utensils with smooth,
flat bottoms.

-- placepots and pansin position beforeswitching on
the cooking zone.

-- Wherever possible, cover pots and pans with alid.

-- switch off the cooking zone a few minutes before
the end of the cooking time, in order to make use
of the residual heat.

-- use the residual heat of the cookingzones forkee­ping food warm or for melting.

-- Positionpots and panscentrally on the cookingzo­nes.

Saucepans and frying
pans

Saucepans and frying pans should not be smaller than
the cooking zone, and preferably not more than
10--15 mm larger than the diameter of the cooking
zone.

Always use cooking and frying utensils with smooth,
flat bottoms.

The bottoms should always be clean and dry. Cook
with a lid in place.

Check that thebottoms of utensils are smooth andun­damaged; bottoms with burrs and sharp edges will
scratch the ceramic glass surface.

Scratches can also be caused by grains of sand (e.g.
originating from the previous washing of vegetables),
drawn over the cooking surface with the pan, or by
burrs and the rims of pan bottoms.

To avoid scratching or damaging the ceramic cooking
surface, pots and pans should be moved on the plate
by lifting them, and not by sliding.

Utensilswith aluminiumand copper bottoms can leave
behindmetallicdiscolorationswhich can only be remo­ved with difficulty or sometimes not at all.

When cold, pan bases normally curve slightly inwards
by approx. 0.1 -- 0.5 mm (are concave). In no case
should they curve outwards (be convex).

Follow any guidelines provided by the saucepan ma­nufacturer. Ensure they are recommended for use on
ceramic hobs.

Check that the appliance is switched off after
use.

161

Cleaning and care

Beforecleaning, makesure thehob is cool and discon­nected from the power supply.

Never use aggressive or abrasive agents,
such as oven sprays, stain or rust removers,
scouring powder, or sponges with an abrasive
effect.

Special cleaning agents such as Hob Brite and ce­ramic hob scrapers are available from department
stores, electrical specialist shops, and in drug and

Cleaning after each use

· Slight, non--burnt soiling can be wiped off with
a damp cloth.

· Burnt soiling has to be removed with a scraper.
Afterwards wipe off the ceramic hob with a damp
cloth, and Hob Brite.

Stain removal

· Light metallic stains (aluminium residues) can
be removed from the cooking zone with aceramic
hob cleaning agent such as Hob Brite when cool.

· Sugar solutions, food stuffs with a high sugar
content, plastics, or kitchen foil -- must be re-

moved immediately with a scraper. If this type of
soilageis not removed immediatelyit cancause ir­reparable damage to the ceramic surface. When
the surfacehas cooled wipeover with a damp cloth
and Hob Brite.

· Before using any detergent or cleaning agent on
the ceramic top, ensure they are recommendedby
the manufacturer for use on ceramic hobs.

· Do not apply any cleaning agents to hot cooking
zones. Ensure any residues are wiped off before
the cooking zones are used again.

Special problems

.. if a chemical cleaner proves inadequate Check whether the use of a scraper is more effective.
.. when darks stains occur If the use of a scraper and a stainless steel cleaning agent proves

unsuccessful, your decor surface has most likely been abraded by using
unsuitable cleaning agents, or by pan bottoms with a scouring effect.
This will not impair the efficiency of your cooking surface.

.. when metallic discolourations appear on
the cooking zones

.. when the surface shows scratches or
impressions

Pots and pans with unsuitable bottoms, or unsuitable cleaning agents have
been used. The discolourations can only be removed with considerable
effort, using a ceramic glass or stainless steel cleaning agent.

These blemishes, caused by scraping or melted on objects, cannot be
removed. This will not impair the efficiency of your cooking surface.

Special problems

We accept no liability for improper handling of the ceramic cooking surface!

Service department.

What do I do when . . .

. . . a buzzing noise is heard when a zone is
heating up?

-- This is not a fault.
It will stop as the heat increases.

. . . discolorations appears in the cooking zone?

-- This is not a result of changes in the material, but is
burned--in remnants that have not been regularly re­moved. They will have no effect of the function orthe
durability of the ceramic hob.

. . . the cooking zones do not function?

Check whether

-- the appliance is switched on,

-- the control lamps are on in the operating field,

-- the respective cooking zone is switched on,

-- the cooking zone power level hasbeen set to the

desired cooking--on level,

-- the fuses inthe house installation(fusebox) have

tripped.
If the fuses repeatedly trip, call in an approved
electrician.

-- the safety cut--out of the cookingzones has been

tripped.

. . . the cooking zones cannot be switched on?

Check whether

. . . the displays all goout except for the ”H” for resid­ual heat?

Check whether

-- the On/Off key has been accidentally operated,

-- the touch switches are partly covered by a damp
cloth, liquid or something similar.

. . . the displays suddenly go out?

Check whether

-- the electricity supply has been temporarily dis­connected, or has failed.

. . . after switching off, no «H»for residual heat is dis­played ?

Check whether

-- The cooking zone has only been in operation for
a short time, and is therefore not hot enough.

If the cooking zoneis hot, pleasecall in anapproved elec­trician, or call our Customer Service department.

. . . one of the cooking zones cannot be switched off
?

Check whether

-- the operating field is locked,

-- a time period of more than 10 seconds has expi­red between the operation of the On/Off key and
switching on the desired cooking zone,

-- the touch surface is too large
(the finger should only be used lightly)

-- the touch switch has been partly covered by a
damp cloth or by a liquid.

-- the operating field hasbeen touched too early fol­lowing a mains failure (to clear the condition,
switch the fuse out and then in again).

-- the touch keys are partlycovered bya damp cloth
or a liquid.

-- the corresponding cooking zonekey (2) is active,
i.e., the decimal point (13) is lit up.

If you call in Customer Service as a result of one of the
items listed above, or as a result of incorrect operation,
the visit of the Customer Service technician will not be
free of charge, even during the guarantee period.
