1. Operations
1.1 Your new hob with Touch-Control operation
This manual covers the models: . GKST 85..
1.2 Touch-Control operating panel
After the supply voltage has been applied (mains connection), a self-test of the control unit (calibration adjustment)
is then carried out. Afterwards, the control unit is in standby mode.
During calibration adjustment a minus sign is lit in the cooking level display (4). It goes out if calibration is
successfully executed.
The touch keys may not be covered by objects or anything else during calibration.

1.3 Touch-Control operations
Each key operation is always confirmed by an acoustic signal.
Pressing the on/off switch key (1) switches on the control system. A “0” is lit for the cooking level indicators (4).
The next action must be carried out within ten seconds, otherwise the control system will automatically switch off
again.
If the minus key (3) is pressed, cooking level 4 is indicated.
Then, a cooking level between 0 and 9 can be selected with the plus or minus key.
The minus key (3) can be used to turn the cooling level down to “0”; if the minus and plus keys (2+3) are pressed
at the same time, the cooking level can be switched off directly.
A “0” appears that goes out after 10 seconds.
As a rule, the complete control system can be switched off at any time by pressing the
on/off key (1).

Parboiling boost
This function makes cooking easier. The cooking zone is
automatically heated at full power and at a specified time (see
table) its is switched back to the cooking level which you pre-
select.
If a cooking zone is switched on with the plus key (2) then
cooking level 9 is indicated. The parboiling boost is now
activated and the decimal point is lit. Any additional keys now
have to be pressed within 10 seconds, otherwise the decimal
point goes out and the parboiling boost is no longer activated.
Select a cooking level between 9 and 0 with the minus key.
The parboil impulse remains activated and the decimal
point is lit. If a key is pressed after the decimal point is no
longer lit then the parboiling boost is no longer activated.
If the cooking level is changed during the parboiling boost then
the parboiling time is automatically (see table) calculated.
Two-circuit- / three-circuit connection
Two-circuit- / three-circuit connection of the respective cooking zone can only be effected after the corresponding
cooking zone has been switched on.
Select the desired cooking level 1-9. Switch on the second heating element by means of the Multi-circuit key (7).
The control lamp (8) of the selected cooking zone lights up. Connect the third heating circuit by pressing the Multi-
circuit key (7) once again. The second control lamp (8) lights up. The corresponding cooking zone must also be
activated in order to switch off the two-circuit / three-circuit connection. The outer heating circuits are switched off
by pressing the Multi-circuit key (7) once again. The control lamps (8) are then no longer lit.
Locking
By pressing the locking key (5) for approx. 2 seconds (lock indicator (6) lights up) all of the buttons, except for the
ON/OFF button, are then locked against accidental use.
The lock indicator then goes out after approx. 2 seconds, the lock is, however, still on. If any key will be pressed
the lock indicator (6) lights up again for approx. 2 seconds.
The following keys can still be used:
• Switch off with ON/OFF key (emergency shutdown)
• Switch off by pressing the plus and minus key simultaneously.
• Unlock
The lock is released by pressing the locking key (5) again.
The lock indicator lights up for approx. 2 seconds and then goes out again.
The lock is now no longer activated.
Residual heat display
The residual heat display is indicated by an illuminated “H” on the corresponding cooking level display (4).

Safety switch-off
The maximum operating time for each individual cooking zone
is limited, and details are shown in the enclosed table of times.
When the safety switch has switched off the touch control
system, an “H” is shown in the cooking level display (4) if there
is still any residual heat left. Pressing the on/off switch key
makes the control system ready for operation again.
If more than one key is pressed simultaneously - with
exception of the minus and plus keys - the control system will
not accept this as a valid command. If one or more keys are
activated for longer than 10 seconds, for example by boiling
over or the weight for a pan, the control system assumes that
there is an error and switches off automatically.

2. Things to watch out for
2.1 Notes on the right types of saucepans
Use only pots and pans with bottoms that are firm, even and as thick as possible. This applies particularly to
cooking with high temperatures, e.g. deep-frying. Uneven bottoms extend cooking times and increase energy
consumption. The best transmission result is obtained when the pots and the cooking zone are of equal dimension.
Always use a lid. Energy is wasted if you cook without a lid placed correctly on the pan.
In order to work directly on the cooking zones, you can use cooking utensils made from fireproof glass or porcelain
if their bottoms are flat polished. Please note the manufacturer’s instructions.
Always take away overflow food.
Clean the hob before using it for the first time. Afterwards, switch on the elements to the
highest level one after the other, without pots, for three minutes in order to eliminate
any odours due to newness and/or in order to evaporate any moisture that may still be
in the heating element. This is necessary so that the electronic circuits function
properly.
2.2 Important
Attention: The surfaces of the heating and cooking zones become hot during use.
Keep small children away at all times.
Always ensure that no hard objects are dropped onto the cooking surface. Under certain circumstances the
material is sensitive to mechanical stresses and strains. A heavy knock or blow in a small area can cause the
ceramic hob to break. If careless treatment results in a break, split or crack, the ceramic hob must immediately be
taken out of use and disconnected from the mains power supply. To do this, switch off the safety switch for the
oven connection in the fuse box. Customer Service must be contacted.
Do not use the glass ceramic hob as a storage area! Never prepare food in aluminium foil and plastic containers
on the hot cooking area.
Do not switch the hob on without using it for cooking. Do not place combustible, volatile or heat deformable objects
directly underneath the hob.
Overheated oil and fat can catch fire; for this reason, never leave food unattended which is cooked with fat or oil,
e.g. chipped potatoes. In addition, make sure that leads from electrical appliances plugged into nearby sockets
cannot come into contact with the hot cooking zones.
Never clean the glass ceramic hob with a steam cleaner or similar appliance!

223693 17
3. Cleaning and maintenance
Always clean the hob after it has cooled down. Even the slightest amount of dirt
will burn into the surface the next time you switch it on. Use only recommended
cleaners. Steel wool, cleaning sponges and abrasive powders scratch the
surface. Do not use oven sprays as these are aggressive and damage the
surface.
Light amounts of dirt
Use a damp cloth or a warm rinse to clean light amounts of dirt from the surface.
Rinse with cold water and then dry thoroughly. Use vinegar, lemon juice or a
calcium dissolving agent to remove water stains from the surface. If these
agents come into contact with the frame, wipe them off with a wet cloth,
otherwise the frame loses its gloss.
Heavy dirt
Use “Sidol Special for Stainless Steel”, “Stahlfix” or “Cerafix” to remove heavy
dirt. Apply the cleaner with kitchen paper and rub it in. Leave it to take effect
than wipe off completely with cold water; then dry the surface thoroughly. Apply
the cleaner with kitchen paper and rub it in. Leave it to take effect than wipe off
completely with cold water; then dry the surface thoroughly. Leave it to take
effect than wipe off completely with cold water; then dry the surface thoroughly.
Cleaning residues on the surface can become aggressive when the hob is
reheated.
Persistent dirt and caking can best be removed with a glass scraper +which
can be obtained in household goods stores, painting and DIY shops or from our
Customer service. Pay attention to handle on purchasing. If you buy a glass
scraper, make sure that the handle is not made of plastic as this will stick to the
hot surface. Take care when using the scraper.
Food that contains sugar may permanently damage the glass ceramic
surface because they can produce scratches after they have become dry. In
order to prevent such surface damage, such substances must be immediately
removed with the glass scraper while they are still hot ,, .
Changes to the colour of the ceramic surface
These have no effect on the function and stability of the glass ceramic. These
colour changes are not changes in the material but food residues which were
not removed and which have burnt in.
Metallic iridescent discolouring is caused by wear from pan bottoms or
unsuitable cleaning agents. This discolouring can be removed with great
difficulty with “Sidol Special for Stainless Steel” or “Stahlfix”. You may have to
clean several times to remove the discolouring.
Worn decoration -. In time, the decoration will wear off and dark stains will
appear as a result of using aggressive cleaning agents and faulty pan bottoms.
If cared for properly, your hob will remain beautiful for many years and cleaning
will be easier.
To care for your hob we recommend that you use “Cerafix”. The high silicone
percentage of this cleaner creates a protective film which keeps off water and
dirt. All dirt remains on the film and can be removed easily. Clean your hob and
the cooking zones regularly.

4. Fitting
4.1 Working surface cut-out
Carry out all cutting out of furniture units and worktops before fitting the
appliance, and remove all sawdust and chips.
The dimensions of the worktop recess can be seen in the dimension
drawing (fig. 1+2)
The cut sections should be sealed with a water-repellent protection
paint.
The worktop and the hob must be fitted horizontally. A tilted hob is
under tension and this increases the danger of breaking.
4.2 Installation
Before installing the hob, check that the all-round hob seal has no gaps.
If the hob is installed in a worktop with a ceramic or similar cover (tiles), remove the hob seal and seal the hob
from the worktop with a plastic seal, such as heat-resistant silicone rubber.
Important! If the cooking surface is located above furniture parts (side panels, drawers,
etc.), then an intermediate bottom must be inserted in order to prevent accidental
contact with the underside of the cooking surface. The intermediate bottom may only
be capable of removal by means of tools and must be attached with a minimum distance
of 20 mm to the underside of the cooking surface so that the mains connection cable
does not touch the underside of the cooking surface (fig. 4).
If the cooking surface is to be inserted over a built-in baking oven, then it must be
equipped with a cooling fan. An intermediate bottom is not necessary in this case.
No cross-bars may be in the area of the cut-out underneath.
Place the hob carefully into the cut-out and fasten it to the worktop with the fasteners.
Screw the fixing elements into the worktop as shown in the drawing. The hob is then pressed carefully from above
into the worktop and fixed as shown in the fig. 3.
Make sure that the worktop and the hob are horizontal. In addition, make sure that no liquids can penetrate
between the edge of the hob and the worktop or between the hob and the wall and come into contact with any
electrical appliances. Use sealing sections, strips, agents, etc. For the purposes of fire safety this appliance is a
Type Y appliance.
This means that it can be installed with its rear side and one of the other sides in contact with room or unit walls
of any height. The other sides may only be in contact with furniture or other appliances with the same height as
the appliance.
4.3 Electrical connections
(Connected loads and model designation: see front of the operating instructions)
This appliance may only be connected to the electricity supply by an approved electrician who must ensure
that the installation complies with the statutory regulations (Germany VDE, Austria ÖVE, Switzerland SEV,
etc.). The electrician must ensure that these regulations and those laid down by the local electricity supply
company are observed.
When connecting the electrical appliance, install an all-pole disconnecting device with a contact gap of at
least 3 mm. Make sure that the local mains voltage is the same as the voltage on the rating label.
To connect the appliance, unscrew the switchbox cover on the underside of the appliance to access the
terminal block. After connecting the appliance, replace the cover and secure the connection cable with the
strain relief clamp.
The connection cable must be at least HO5 VVF.
Make sure that the excess cable length is not laid in the hob’s installation area.
See fig. 4 for the position of the cable cut-out.
