1 General information
1.4 Data protection
During operation your cooktop extractor saves pseudonymised
data such as menu settings entered by you, operating hours
of the individual technical units and the number of functions
selected. Furthermore, your cooktop extractor documents errors
in combination with the number of operating hours.
Data can only be read out manually via your cooktop extractor.
This decision is therefore your responsibility.
These saved data then enable a rapid error search and
troubleshooting in the event of servicing.
1.5 Presentation of information

4 Installation
4.1.1 Operating the cooktop extractor with a
fireplace that depends on the air in the
room
i The state and regional laws and regulations must be
observed with regard to the exhaust duct design.
i A sufficient air supply must be ensured.
Fireplaces that depend on the air in the room (e.g. gas, oil,
wood or coal-fired heaters, continuous-flow water heaters,
instantaneous water heaters) draw in air from the room in which
they are installed and release the exhaust fumes into the outside
air via an exhaust system (e.g. chimney).
If the cooktop extractor is used in exhaust mode, it draws
in air from the room in which it is installed as well as from
neighbouring rooms. Without sufficient air, there will be a drop in
air pressure. Toxic gases could be drawn out of the chimney or
extraction ducting and back into the room.
Fig. 4.1 Exhaust air installation – not permitted
Fig. 4.2 Exhaust air installation – correct
XXIf simultaneously operating both a fireplace and the cooktop
extractor in the same room, ensure that:
XO the maximum low pressure is 4Pa (4 x 10-5bar);
XO a safety device (e.g. window contact switch, low pressure
warning device) is used to ensure that a sufficient supply
of fresh air is guaranteed;
XO the exhaust air is not be ducted into a chimney that is
used for exhaust gases of devices operated with gas or
other combustibles;
XO the installation is checked and approved by an authorised
certified engineer (e.g. heating engineer).
i No window contact switches may be installed that
separate the control unit from the power supply (phase
separation). Only the Home In interface is to be used.
XXObserve all safety and warning information (see the Safety
chapter).
XXFollow the enclosed manufacturer’s information.
4.1 General installation information
i The appliances must not be installed above cooling
devices, dishwashers, stoves, ovens, washing machines
or dryers.
i The contact surfaces of the worktops and wall sealing
strips must be made of a heat-resistant material
(up to approx. 100 °C).
i Worktop cut-outs must be moisture-sealed using suitable
means and, where necessary, fitted with a thermal
insulator.
i External devices may only be connected to the cooktop
extractor connections provided.
i Extremely bright lights aimed directly at the appliances
can cause colour variations in the appliances and are
thus to be avoided.
General installation information for cooktops
i To ensure that the cooktops perform optimally at all
times, there must be sufficient ventilation beneath the
cooktops.
i The performance of the cooktops is affected or the
cooktops overheat if the warm air beneath the cooktops
cannot escape.
i If a cooktop overheats, the power is automatically
reduced or the cooktop is switched off completely
(see Overheating protection).
i If cable protection (false floor) is planned beneath the
appliance, this must be fitted so it does not obstruct
ventilation.
XXMake sure that the area below the cooktop has a sufficient air
supply.
Additional installation notes for Australia and New Zealand
(AU/NZ):
i The gas hose must be inspected every 5 years and
replaced if necessary. The gas hose must meet the
requirements of AS/NZS 1869.

4.4.3 Recirculation when using the cooktop
extractor as a recirculation system
In the case of recirculation systems there must be a return flow
aperture in the kitchen units:
XO > 500 cm² (per air cleaning box) in combination with cooktops
CKFI, CKI, CKIW, CKCH, CKCB and CKT
XO > 1000 cm² (per air cleaning box) in combination with gas
cooktop CKG
i If several extractor systems are operated in recirculation
mode, the return flow aperture for each air cleaning box
must be calculated correspondingly. Example:
2 recirculation systems = 2 x (> 500 cm²) or
2 x (> 1,000 cm²) in the case of gas appliances
For recirculation, the necessary return flow aperture can be
created using a shortened plinth. A slatted plinth with at least
the minimum opening cross-section can also be used.
XXEnsure that the return flow aperture is large enough.
