Installation
u
Observe all safety and warning information (see "2 Safety").
u
Follow the enclosed manufacturer's information.
4.1
General installation
instructions
The appliance must not be installed above cooling devices,
dishwashers, stoves, ovens, washing machines or dryers.
The contact surface of the worktops and wall sealing strips
must be made of a heat-resistant material (up to approx.
100°C).
Worktop cut-outs must be moisture-sealed using suitable
means and, where necessary, fitted with a thermal insulator.
External devices may only be connected to the cooktop
extractor connections provided.
Extremely bright lights aimed directly at the appliances can
cause colour variations in the appliances and are thus to be
avoided.
General installation instructions for cooktops
u
Make sure that the area below the cooktop has a sufficient air
supply.
To ensure that the cooktops perform optimally at all times,
there must be sufficient ventilation beneath the cooktops.
The performance of the cooktops is affected or the cooktops
overheat if the warm air beneath the cooktops cannot escape.
In the event of overheating, the cooktop power is reduced or
the appliance is switched off completely.
If cable protection (false floor) is planned beneath the
appliance, this must be fitted so it does not obstruct
ventilation.
Additional installation instructions for Australia and New
Zealand (AU/NZ):
The gas hose must be checked every 5 years and replaced if
necessary. The gas hose must meet the requirements of AS/
NZS 1869.

4.1.1
Operating the cooktop extractor in
the exhaust air mode and where
there is a fireplace dependent
upon the air supply in the room
National and regional laws and regulations must be observed
with regard to the exhaust duct design.
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 air 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.

Exhaust air installation – not permitted

Exhaust air installation – correct
u
If simultaneously operating both a fireplace and the cooktop
extractor in the same room, ensure that:
T
the maximum low pressure is 4 Pa (4 x 10–5 bar);
T
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;
T
the exhaust air is not channelled into a chimney that is used for
exhaust gases of appliances operated with gas or other
combustibles;
T
the installation is checked and approved by an authorised certified
engineer (e.g. heating engineer).
