Safety instructions
for connection and functions
"Küppersbusch cookers are manufactured in accordance
with the applicable safety regulations.
"The cookers may only be connected up to the mains,
serviced and repaired by a qualified electrician according
to the valid safety regulations. Work carried out incorrectly
will endanger your safety.
"When the appliance is connected up it must be ensured
that there is a device which makes it possible to disconnect
it from the mains at all poles with a contact opening width
of at least 3 mm. Line-protecting switches, fuses or
contactors are suitable cut-out devices.
"For honeycomb combinations with a depth of more than
500 mm, use only worktops with a depth of at least
650 mm.
"Caution:
The honeycomb sensor control element must not be
exposed to severe mechanical shocks!
"The surfaces of the heating and cooking zones become
very hot when in operation.
Therefore always take care and make sure to keep
children away.
for the cooking zones
"Overheated fat and oil may ignite spontaneously. Food
cooked in fat and oil, e.g. chipped potatoes, should not be
left unattended. Never use water to extinguish burning fat
and oil! Place the lid on the pan, switch off the cooking
zone and remove the pan from the cooking zone.
"If cracks, fractures or any other defects appear on your
glass ceramic hob, switch off the honeycomb combination
as quickly as possible. Disconnect the mains fuse imme-
diately and call Customer Service.
"If a cooking zone cannot be switched off due to a fault in
the sensor control, disconnect the mains fuse immediate-
ly and call Customer Service.
"Be careful when using other kitchen appliances. Electric
cables must not be allowed to come into contact with the
hot cooking zones.
"Do not deposit items on the honeycomb hob which do no
belong there.
"Do not place combustible or inflammable objects onto the
hob as this might present a potential hazard if the applian-
ce is switched on unintentionally.
"Do not switch on the cooking zones if you are not cooking
anything. Never use the honeycomb cooking zone to heat
the room! This would result in improper operating con-
ditions.
"Do not place aluminium foil or plastic onto the cooking
zones. Keep everything away from hot cooking zones
which is likely to melt, e.g. plastic, foil, and in particular
sugar and foods with a high sugar content. Immediately
remove any sugar while it is still hot with the help of a
razor blade scraper in order to prevent damage.
"Do not allow dirt or food which has boiled over to become
encrusted by repeated use of the hob.
"Calcium deposits will damage the honeycomb hob.
"If you keep any pets which could come near the hob, the
childproof lock must be activated.
4

What to do before
using the appliance
for the first time
Remove excess materials and packaging. Before preparing
food for the first time, clean the honeycomb hob with a
damp cloth and a small amount of washing up liquid.
The hob is resistant to temperature shocks (cold and heat)
and is also otherwise highly resistant.
Make sure that no hard objects are dropped onto the hob.
Impacts concentrated on a small point may result in fracture.
Please follow the cleaning and maintenance instructions.
Above all, keep the sensor pads clean as soiling may
otherwise be interpreted as finger contact. Never place
objects (pans, tea-cloths, etc.) on the sensor pads! If the
contents of saucepans boil over onto the sensor pads, we
recommend that you operate the central ON-OFF sensor.
When the cooking zones are switched on, the heating may
hum for a short while. This is due to technical reasons and
has no influence on the appliance’s quality or functions.
Hot saucepans must not be allowed to cover the sensor
pads, as this will cause the appliance to switch off
automatically.
Hot saucepans should only be placed onto stone worktops.
Never pull hot saucepans onto or across worktops with
surfaces made of synthetic materials, e.g. Resopal, Duropal,
etc., or worktops made of
CORIAN. Always place
saucepans on the honey-
comb saucepan stands,
item no. 041.
Advice on the right type of saucepans
Only use pots and pans with a flat, smooth base.
Saucepans with concave bases take considerably
longer to heat up and also increase energy
consumption. Saucepans with rough bases
will scratch the surface of the ceramic hob if
they are slid about. When using kitchenware
made of heat-resistant glass or china, please
observe the manufacturer’s instructions.
Choose a pot or saucepan whose diameter matches that
of the cooking zone.
This will save energy, reduce cooking times
and avoid overheating the cooking zone.
When cooking, always put a lid on the sau-
cepan.
This will save a lot of energy. Food and liquids
only boil over when the temperature is too
high. You can adjust the temperature precisely
for the individual cooking zones. With a little
experience you will soon find the right heat
setting, so that nothing will boil over, even when a lid is on
the saucepan.

Sensor operation of the control honeycomb
As you can individually select the number and position of
the honeycomb cooking zones, the sensor honeycombs also
have to conform to the configuration you design. Your creativity
can be given free rein. The markings in the control
honeycomb repeat the layout of the cooking zones on the
worktop, so operation is as clear and simple as possible.

DControl fields for the cooking zones with plus and minus-
sensors (the layout is only shown as an example)
A sensor honeycomb can control up to 6 honeycomb
cooking zones. If more than 6 honeycomb cooking zones
are to be combined, a second sensor honeycomb will be
required. The sensor honeycomb always includes a control
for dual-circuit cooking zones and the automatic boost
function as well as a childproof lock which functions by
deactivating the electronic system.

Switching on the appliance
Touch the ON-OFF pad for about 2 seconds. A vertical bar
will light up above the lock pad (sensor lock).
The appliance is now ready to be put into operation (standby
mode).
Each cooking zone can now be controlled individually.
Switching all functions off
Briefly touch the ON-OFF pad (for about 0.3 seconds). The
vertical bar will be extinguished.
The control honeycomb switches off again automatically:
– if no further pad is touched within 20 seconds *,
– if it is left unused for 10 minutes after operation or
– if the sensor pad of a cooking zone is touched for longer
than 20 seconds *.
* An acoustic signal already sounds after 10 seconds to
warn you that the appliance will switch off after another
10 seconds.
Setting the cooking zones
One cooking zone has 9 settings (1-9).
The settings are shown in the displays for the individual
cooking zones.
The required setting is selected by touching the plus pad
(cooking without the automatic boost) or by touching the
minus pad (cooking with the automatic boost).
There is no zero setting.
All the cooking zones are provided with an automatic boost
function.
Cooking without the automatic
boost function
Touch the plus pad. The cooking zone switches on at
setting 5. Now select the desired setting.
2 secs.

Cooking with the automatic boost
function
Touch the minus pad. The cooking zone switches on at
setting 9 and the automatic boost function is activated. Now
turn the heat down to the required setting. When the auto-
matic boost has finished, the cooking zone automatically
switches back to the selected setting.
During automatic operation, an ”A” blinks in the display
alternately with the selected setting.
At the same time, it is possible to switch backwards and
forwards between the individual heat settings; the remaining
time for the automatic boost function remains unaltered.
Switching off the cooking zones
Touch the plus pad and the minus pad simultaneously for
about 3.5 seconds.
Make sure that the display goes out,
or
Touch the minus pad.
The settings count down.
After setting 1, setting 0 is displayed for 2 seconds. Then
the cooking zone will switch off.
Switching on the dual-circuit
cooking zone (EKW 306.1)
The standard function is for the cooking zone with the
smaller diameter to heat up. If you are using larger sauce-
pans, you can also switch on the outer zone with the larger
diameter.
Dual-circuit cooking zones are indicated by a flashing dot in
the relevant display.
Touch the plus pad and the minus pad at the simultaneously
for about 1 second. The pilot light next to the display for the
cooking setting lights up and an acoustic signal will be
heard.
Switching off the dual-circuit
cooking zone
Touch the plus pad and the minus pad simultaneously for
about 1 second. The pilot light next to the display for the
cooking setting will go out and an acoustic signal will
indicate that the outer cooking zone has been switched off.

Activating the childproof lock
The childproof lock, which consists of a key and a lock
sensor, can be used to protect the appliance against un-
authorised use by locking the settings. In order to use the
childproof lock the hob must be switched on.
First of all, touch the key pad until you hear an acoustic
signal.
Then touch the lock pad until you hear an acoustic signal.
When the childproof lock is activated, this is indicated by
3 vertical bars instead of the standby indicator.
The childproof lock can also be activated while you are
cooking. The cooking settings of the cooking zones then
cannot be turned down or turned up.
The childproof lock will remain active even after the appliance
has been switched off.
Cancelling the childproof lock
To put the appliance back into standby status, you must
cancel the childproof lock.
To do this, first touch the key pad until you hear an acoustic
signal.
Then touch the lock pad until you hear an acoustic signal.
When the childproof lock has been cancelled, the standby
indicator will appear in the vertical bar.

ei
The minute minder
The minute minder has two purposes: to switch off func-
tions and to serve as a reminder. It can be set for a maxi-
mum of 99 minutes. It is activated by touching the plus pad
or the minus pad.
The time can be set by touching the plus pad (starting at 0)
and the minus pad (starting at 99).
Touching both the plus pad and the minus pad simultaneously
will reset the minute minder to 0.
When the set time has come to an end, a signal will sound
for about 30 seconds.
”00" will flash in the display.
The signal can be interrupted before it has come to an end
by simultaneously pressing the plus pad and the minus pad.
Automatic switch-off
Set the minute minder to the desired time period.
The cooking zone which is to be switched on is selected via
the Minute Minder pad. A pilot light in the clock symbol of
the corresponding operation field shows which cooking zone
is currently selected.
If the pad is touched for a longer period of time, the next
cooking zone will be selected.
When you have reached the desired cooking zone, remove
your finger from the pad.
After 5 seconds the selection is confirmed by an acoustic
signal.
The cooking zone is now set, but the time can still be
varied.
If the plus pad and the minus pad are touched simultaneous-
ly, this will deactivate the automatic switch-off function and
reset the clock to 0.
When the time has expired, the selected cooking zone will
switch off automatically. A signal will sound for about
30 seconds.
10

The residual heat display
Each cooking zone has its own residual heat display. When
the cooking zone has been switched off an “H” will appear
in the display for the cooking setting for about 30 minutes.
The residual heat display also remains on even after the
control honeycomb has been switched off.
Other functions
If two or more pads are touched at the same time, no
control function is activated.
This can happen, for example, if:
– the distance between your hand and the other pads of
the control honeycomb is too small,
– a saucepan has been accidentally placed on the pads.
Exceptions:
– Switching the dual-circuit cooking zones on or off
– Switching the cooking zones off.
If several pads are touched simultaneously or a plus pad is
touched for longer than 10 seconds after the highest
cooking setting has been reached, a signal will sound.
After 20 seconds the entire electronics will switch off.
The appliance will not switch on again automatically after a
power failure.
11

Cleaning and caring for your appliance
"Never use abrasive cleaning agents!
"It is usually sufficient to clean the appliance each time af-
ter use, using a damp cloth and a little washing up liquid.
Then wipe dry.
"Food which has boiled over and become encrusted should
first be softened with a wet cloth. Then remove with a
glass scraper. Remove sugar and melted plastic
immediately while the hob is still hot.
"Clean the honeycomb hob each time after use. Make
particularly sure that the sensor pads are always clean as
soiling may be interpreted as finger contact. Remove any
soiling immediately. Never place objects (pans, tea cloths,
etc.) on the sensor pads! If anything boils over onto the
sensor pads, we recommend that you operate the central
ON-OFF sensor.
"Apply a care agent to the honeycomb hob once a week.
This produces a protective coating, and also makes daily
cleaning easier. Please observe the instructions of the
respective cleaning and care agent manufacturers.
Stubborn stains can also be dealt with by a care agent.
Then wipe with sufficient water and rub dry with a cloth.
"Important:
Never attempt to clean the honeycomb cooking zones or
in particular the sealing joints with sharp, scratchy or
pointed objects!

Cutting an opening in the worktop
Cutting an opening in worktops made of wood or synthetic materials
The opening is cut in two steps. First cut an opening for the
heating or control element and then the recess for the hob.
– Draw the positions of the individual honeycombs.
– Cut the complete opening for the undertray of the
honeycomb hob.
Then make the recess for the six-sided glass ceramic
surface.
For making the recess, at least a recess and shaping
machine with a guide bead is required.
The outer dimensions of the recess should always be
approx. 2–6 mm greater than the outer dimensions of the
hob so as to allow for a sealing (see: ”Bonding the honey-
comb cooking zones in place”).
For worktops made of wood or synthetic materials, the six-
sided recess must be 5.5 mm deep.
The resulting projection (at least 1 mm) of the ceramic sur-
face over the worktop serves to protect the surface of the
worktop from hot saucepans being unintentionally being
placed on it.
An example of the dimensions of the honeycomb hob system
Dimensions of 2 honeycomb
cooking zones including a
3 mm silicon seam
The silicon seam can have a
breadth of 1–3 mm.
Please note that the dimensions
of the opening for the honey-
comb will also vary depending
on the breadth of the seam.
Correct: Allow an extra 1-3 mm for the silicon seal!
Incorrect: Allow an extra 1-3 mm round each honeycomb.

The opening for the heating element controls
If several honeycomb cooking zones are to be combined,
the webs and nodes created by the cutouts must be pre-
served. They serve to maintain the strength of the worktop
and must not be removed.
The cutouts for the undertrays of EKW 307.1/306.1/306.0
should always point outwards and never inwards towards
the nodal point of several honeycomb cooking zones. The
shape of the nodal points preserves the stability of the work-
top – whether it is made of wood or granite – to such an
extent that no additional reinforcement is necessary. The
honeycomb hob system obtains ultimate stability when it is
bonded with the worktop.
*Only permitted with worktops with a depth of 650 mm.
Notes on installation
"The worktop must be level!
"There must be a lateral clearance of at least 300 mm
away from any high cupboards.
"There must be no crossbars located under the worktop
opening for the honeycomb hob. If necessary, they must
be scaled down to the dimensions of the opening.
"A panel must be fitted under the honeycomb hob to pre-
vent any accidental contact with connection cables. The
minimum clearance to the top edge of any lower unit cup-
board must be 100 mm.
It must not be possible to remove the panel unless with
the aid of tools. The rear wall of the lower cupboard must
be sawed off above the panel.
"The appliance is one of type “Y” as regards the protection
of surrounding surfaces against overheating.

Cutting an opening in worktops made of stone
The ceramic surface can be built into stone worktops in such a way that it is completely flush.

First cut the shape of the honeycomb combination out of the
worktop in one piece. Do not forget to add the allowance for
the silicon seal (see p. 15)!

When finished, bond the cutout section back in place into
the worktop, but this time 6.5 mm deeper.
Note: As with worktops of wood, the worktop opening can
be milled out instead of being cut out and bonded in place.

Make the openings for the undertrays of the honeycombs
out of the cutout section.

The bonding compound must have a
temperature resistance of > 80 °C.
16

Bonding the honeycomb cooking zones in place
"To prevent damage to the worktop or the honeycomb hob,
it is essential for the worktop/honeycomb system to be bon-
ded with a permanent and absolutely watertight seal.
"The parts to be bonded together must be dry and
absolutely free of grease.
"For bonding the honeycomb zones in place, you will
require barrier primer, type Sperrprimer 101 and the
heat- and moisture-resistant silicon adhesive Silikon-
kleber Pactan 7056 manufactured by Heidelberger
Baustofftechnik. These materials can also be obtained
from the Küppersbusch Spare Parts Department.
It is absolutely necessary to observe the remarks
concerning these two products. You will find them in
the enclosed processing indications! There you will also
find a calculation formula for the hardening of the silicone
adhesive. Do not operate the cooking zone before the
hardening process is over as otherwise the silicone
adhesive can be damaged!
"Bond the honeycombs round the edges only!
"Never place the cooking zones onto the worktop or onto
the floor if the glass ceramic surface is unprotected. Dirt
(slivers of metal, remains of stone etc.) can cause
scratches on the glass ceramic surface). Always place
cardboard or a woollen blanket underneath.
First, apply the barrier primer to the fitting surfaces of the
honeycombs and all cut surfaces of the worktop to approx.
1 mm beyond the edge of the cut.
– On strongly absorptive surfaces (e.g. chipboard) apply a
thick coating of primer with a brush. On weakly absorptive
surfaces (e.g. the fitting surfaces of the honeycombs,
marble, granite) it is sufficient to apply a thin coat of primer
with a piece of felt.
Important: after application, the primer must always be
left to air for about 30 minutes.
– Then apply a bead of Pactan along all the cut surfaces
of the individual honeycombs and to the outer edge of
the recesses, as shown.
Pactan takes approx. 20 minutes to take effect. If you
think you will need more time for bonding the honey-
combs in place, apply Pactan and fit each honeycomb
separately
– Now position the honeycomb cooking zones.
– Finally, fill the gap between the honeycomb cooking
zones and the worktop with Pactan. Smooth the seam
with a spatula and a liquid detergent solution.
The honeycomb cooking zones do not usually need to be
screwed into place. The positioning brackets only serve for
adjustment during installation or for securing purposes if the
worktop is to be transported complete with the honeycombs
in place.
Notes on further information material
Info diskette
By contacting Küppersbusch Vertriebsgesellschaft mbH you
can also send for a diskette with drawings of the worktop
openings with different honeycomb layouts.
The drawings (on a scale of 1:2 (½ size), paper format DIN
A0) are available in the graphical formats Windows Metafile
(*.WMF), AutoCAD (*.DWG) and PostScript (*.EPS).

Electrical connection
"The appliance should only be connected up to the mains by a qualified and authorised electrician.
"The statutory regulations and the conditions for connection of your local electricity board must be observed to the letter.
"During installation, the control honeycomb must be disconnected from the mains.
"When the appliance is connected up to the mains, it must be ensured that there is a device which makes it possible to
disconnect it from the mains at all poles with a contact opening width of at least 3 mm. Line-protecting switches, fuses or
contactors are suitable cut-out devices.
Connecting the cooking honeycombs to the control honeycomb
"Only the cooking honeycombs EKW 307.0, EKW 306.0
and EKW 306.1 should be connected to the control honey-
comb (ESW 308.6). Failure to observe this could produce
dangerous conditions.
"One control honeycomb can control a maximum of
6 cooking honeycombs.
"Up to 3 dual-circuit cooking zones of type EKW 306.1 can
be connected to each control honeycomb.
It is essential to carry out the connections in accordance
with the enclosed circuit diagram!
Enclosed with control honey-
comb ESW 308.6 is a circuit
diagram in which each cooking
zone is provided with a number.
This number can also be found
on the connection cables for the
cooking zone. This makes it
easy to determine which sensor
pads control which cooking
zones.
The plug-type connector
– for the single-circuit cooking
zones EKW 307.0 and 306.0
has 3 connections,
– for the dual-circuit cooking
zone EKW 306.1 has
4 connections.
The connections are marked on the plugs (N / L1 / L2 / etc.).
Connecting the appliance to the mains
"Connection to the mains should only be carried out by an authorised electrician. The generally accepted rules of technology
and the connection regulations of your local electricity board must be strictly complied with.
"During installation, the control honeycomb must be disconnected from the mains.
– Open the separator on the installation side.
– Insert the compact plug of the control honeycomb into
its counterpart on the connection side.
– Connection rating: 400 V 3N~50Hz
Power rating: max. 8.7 kW
Connection to single-phase mains is only possible if at most
two single-circuit and one dual-honeycomb are connected.

Connecting the cooking honeycombs to the built-in oven or control element
The honeycomb cooking zones can also be connected to a
Küppersbusch built-in oven or a Küppersbusch control
element. The following points must be observed:
– It is always necessary to connect four honeycomb
cooking zones to the oven.
Out of these no more than two honeycombs should be
dual-circuit cooking zones, EKW 306.1.
– In arranging the honeycombs it must be ensured that
the allocation of the control units is perfectly clear
(see drawings below).
Three different adapters are available to connect the honey-
comb cooking zones to the oven, depending on the layout of
the cooking zones:
Aif 2 dual-circuit cooking zones are used,
front left and rear right
Bif 1 dual circuit cooking zone is used at the front left
Cif no dual-circuit cooking zones are used
The adapters are provided with a code (1 - 4) and must be
ordered separately. The codes have the following meanings:
1Cooking zone at front left
2Cooking zone at rear left
3Cooking zone at rear right
4Cooking zone at front right
