The cooktop extractor is the central component and contains
all of the electronics for operating the entire system. It is not
possible to operate the system or individual components
without a cooktop extractor.

3.1.3 How it works
Depending on the model you purchased, the cooktop extractor can
be operated as an exhaust air or a recirculating air version.
Exhaust air
The air suctioned away is purified by the grease filter and expelled
into the open air via a duct system.
The exhaust air must not be expelled into:
T a smoke or exhaust gas flue that is in operation
T a shaft used for the aeration of rooms where fireplaces are
installed.
If the exhaust air is to be directed into a smoke or exhaust gas flue
that is not in use, the installation must be checked and approved by
the responsible heating engineer.
If the cooktop extractor is used in an exhaust air system, the
extractor power is automatically increased for the first 20
seconds when set on a lower power level (wall sleeve
function).
Recirculation
The air suctioned away is purified by the grease filter and an activated
charcoal filter and fed back into the room in which the appliance is
installed.
To prevent odours in recirculation mode, an odour filter must be
used. For health and hygiene reasons, the activated charcoal filter
must be replaced at the recommended intervals (Cleaning and
maintenance).
In recirculation mode, ensure sufficient ventilation and
aeration to expel humidity.
If the cooktop extractor is used in a recirculating air system,
when a power level is set the operating time is automatically
deducted from the recirculation filter service life. The
remaining filter service life can be seen in the menu.

3.2.6 Sounds
The volume of the acoustic signals can be set in the menu
(10% to 100% ).
Safety-relevant acoustic signals are always emitted with the
volume at 100%.
The acoustic signals from the cooking zone timer and short-
time timer are always emitted with the volume at 100%.
The system basically differentiates between three different types of
acoustic signals:
Acoustic signal Purpose
Short beep (0.25 s ) Confirmation of a selection
Sequence of beeps Interaction required
Long beep (0.75 s ) End of a function
Tab.3.8 Sounds
3.2.7 Filter service display
The maximum service life of the recirculation filter is defined by the
filter type configured in the system (filter service life). Depending on
the type of filter fitted, the filter service display will be activated after
300 or 600 operating hours.
T If the fan symbol lights up yellow and the multi-function display
shows after switching on the cooktop extractor, this is
informing you that the filter needs to be changed soon.
T If the fan symbol lights up in signal red and the error code
is shown in the multi-function display after switching on the
cooktop extractor, the end of the filter service life has been
reached and the filter must be replaced (see"7.3.4Replace the
activated charcoal filter").
If the service life of the activated charcoal filter is exceeded,
the correct functioning of the system may be affected. It is
still possible to use the cooktop extractor, however, the
warranty and guarantee claims shall then be invalid. The
components of the grease filter require regular cleaning
regardless of the filter service display.
3.3 Cooktops
The cooktops are the variable components for the system and
can only be operated in conjunction with the cooktop extractor.
You can see exactly which appliances have been installed in
your system on the penultimate page of the Operating
instructions (see"10Identification plates").

3.3.3 How the induction cooktops work
An induction coil is located underneath an induction cooking zone. If
the cooking zone is switched on, this coil creates a magnetic field
that acts directly on the base of the pot thus heating it up. The
cooking zone is only indirectly heated up by the heat emitted by the
pot. Cooking zones with induction only work if the cookware has a
magnetisable base.
Induction automatically takes into account the size of the cookware
used which means that only the area in the cooking zone covered by
the base of the pot is heated up.
u Observe the minimum pot base diameter.
Power levels
The high power output of induction cooktops results in the very quick
heating up of cookware. In order to avoid burning food, slight
adjustment is needed in comparison to conventional cooking systems
when selecting the power level.
Activity Power level
Melting butter and chocolate, breaking up gelatine
Keeping sauces and soups warm, soaking rice -
Cooking potatoes, pasta, soups and ragouts,
steaming fruit, vegetables and fish, defrosting food
-
Frying in coated pans, moderate frying (without
overheating the fat) of pork cutlets or fish
-
Heating up fat, browning meat, cooking thickened
sauces and soups, making omelettes
-
Cooking large amounts of liquids, grilling steaks
and heating water

Tab.3.10 Recommendations for power levels
The specifications provided in the table are standard values.
Depending on the cookware and filling quantity, it is recommended to
either decrease or increase the power level.
Suitable cookware
Cookware with this symbol is suitable for induction cooktops. The
cookware used for the induction cooktop must be made of metal,
feature magnetic properties and possess an ample base.
Suitable cookware is made of:
T stainless steel with a magnetisable base
T enamelled steel
T cast iron

Tab.3.11 Minimum cookware diameter
u Perform a magnet test, if necessary. If a magnet sticks to the base
of the utensils, they are normally induction compatible.
u Pay attention to the cookware base. The base of the cookware
should not show any sign of curvature (exception: wok cooktops).
Due to incorrect hob temperature monitoring, this curvature may
cause the cookware to overheat. To avoid scratching the cooktop,
the base of the cookware must not have any sharp grooves or
sharp edges.
u Place the cookware (without a mat or similar) directly onto the
glass ceramic.
The heating and heat-through times for the cookware base, as
well as the cooking results, are significantly influenced by the
structure and material of the cookware.
u The induction wok (HIW1) is ideal for the Induction wok cooktop
and is available as an accessory.

Noises
The following noises may occur in the cookware when using induction
cooking zones, depending on the material and the finish of the base:
T Humming may occur when using a high power level. This decreases
or disappears when the power level is decreased.
T Crackling or whistling may occur due to cookware bases being
made of different materials (e.g. sandwich base).
T Clicking sounds may occur during electronic switching procedures,
especially at low power levels.
T Whirring may occur when the cooling fan is switched on. In order
to increase the service life of the electronic system, the cooktop is
equipped with a cooling fan. The cooling fan switches on
automatically if the cooktop is used intensively. You will hear a
whirring sound. The cooling fan may continue to run after the
appliance has been switched off.
3.3.4 How the Hyper and HiLight
cooktops work
Under the cooking zone is a radiant heating element with a heating
tape. When the cooking zone is switched on, the heating tape
generates radiant heat, which radiates to the cooking zone and heats
it up.

Tab.3.12 Recommendations for power levels
The specifications provided in the table are standard values.
Depending on the cookware and filling quantity, it is recommended to
either decrease or increase the power level.
Power setting on the Hyper cooktop
The front cooking zone on the Hyper glass ceramic cooktop is fitted
with a temporary power setting.
T is displayed.
The power setting can be used in order to quickly heat up large
quantities of water. If the power setting is activated, the cooking
zones will run at extra high power. After 10 minutes, the cooking zone
automatically switches back to power level 9.
Suitable cookware
Cookware with this symbol is suitable for radiant heating
elements. The cookware used for radiant heating surfaces must be
metal and have good heat conducting properties.
Suitable cookware is made of:
T stainless steel, copper or aluminium
T enamelled steel
T cast iron
u Pay attention to the cookware base. The bottom of the cookware
should not show any sign of curvature. Due to incorrect hob
temperature monitoring, this curvature may cause the cookware to
overheat. To avoid scratching the cooktop, the base of the
cookware must not have any sharp grooves or sharp edges.
u Place the cookware (without a mat or similar) directly onto the
glass ceramic.
The heating and heat-through times for the cookware base, as
well as the cooking results, are significantly influenced by the
structure and material of the cookware.
3.3.5 How the gas glass ceramic
cooktop works
If a cooking zone is switched on, the flame generates heat, which
directly heats the base of the cookware. The gas flame is controlled
by a highly accurate electronic gas control system (e-gas system).
Among other things, servomotors are used to accurately control each
gas burner. These servomotors calibrate themselves from time to
time and typical humming noises can be heard that are totally normal
and do not constitute a malfunction. The advantage of this electronic
gas control system is the optimum, repeatable heat regulation, which
means that the selected power levels are identical in every cooking
session. In addition, a clean, constantly increasing flame is formed at
every power level. Furthermore, if necessary, it can be automatically
reignited.
The cooktop has automatic ignition.
Power levels
The power is adjusted using power levels 1 – 9 and P. The output of
gas cooktops means that food is heated quickly. In order to avoid
burning food, slight adjustment is needed in comparison to
conventional cooking systems when selecting the power level.
Activity Power level
Keeping cooked meals warm -
Browning chopped vegetables, fried eggs, veal,
poultry
-
Grilling prawns, corn on the cob, schnitzel, beef,
fish or burgers
-
Bringing large amounts of liquid to the boil,
searing steaks
-
Heating up water
Tab.3.13 Recommendations for power levels
The specifications provided in the table are standard values.
Each gas cooking zone is equipped with a safety
thermocouple. This element detects if the flame has gone out
(e.g. if a pan has boiled over or there is a strong draught). The
gas supply is then turned off and the burner is automatically
reignited. If reignition is not possible, the gas supply is
stopped. A gas leak is therefore prevented.
Suitable cookware
Cookware with this symbol is suitable for gas cooktops.
Suitable cookware is made of:

T aluminium
T cast iron
Adhere to the dimensions in the table:
Burner Minimum pan

Recommended pan
diameter
Normal burner 120 mm 140–200mm
High-power burner 160 mm 180–240mm
Tab.3.14 Pan diameters
Only use cookware with a diameter that is within the given
dimensions. If the diameter is too large, the hot gases flowing
outwards from under the base may damage the worktop or
any non-heat-resistant wall, e.g. with panelling, as well as part
of the cooktop and the cooktop extractor. Bora shall not be
held liable for any such damage.
The heating and heat-through times for the cookware base, as
well as the cooking results, are significantly influenced by the
structure and material of the cookware. Cookware with a
thick base ensures more even heat distribution. In the case of
a thin base there is a risk of the food becoming overheated in
places. The cooktop may also become damaged.
Take special care not to overheat the cookware as the base
can become deformed. For this reason, you should never heat
up cookware when empty.
Cookware with an uneven base may tip over. A slight wobble
can never be completely ruled out.
3.3.6 How the Tepan stainless steel grill
works
Under each grilling zone there is a heating element. When a grilling
zone is switched on, the heating element generates heat that directly
heats the grill surface.
Power levels and temperature ranges
The power is adjusted via power levels that are also shown in the
operating panel display in °C (temperature display).
Power level Temperature in °C
1 = 150
2 = 160
3 = 170
4 = 180
5 = 190
6 = 200
7 = 210
8 = 220
9 = 230
P = 250
Tab.3.15 The temperatures corresponding to the power levels
The power output of the Tepan stainless steel grill heats food
extremely quickly. A slight adjustment is needed in comparison to
conventional cooking systems when selecting the temperature in
order to avoid burning food.
