Important information
Installation Instructions:
Old appliances are not worthless
rubbish. Valuable raw materials can be
reclaimed by recycling old appliances.
Before disposing of your old appliance,
render it unusable.
You received your new appliance in a
protective shipping carton. All packaging
materials are environmentally friendly and
recyclable. Please contribute to a better
environment by disposing of packaging
materials in an environmentally-friendly
manner.
Please ask your dealer or inquire at your
local authority about current means of
disposal.
The extractor hood can be used in
exhaust air or circulating air mode.
Always mount the extractor hood over
the centre of the hob.
Minimum distance between electric
hob and bottom edge of extractor hood:
430 mm, Fig. 1.
The extractor hood must not be
installed over a solid fuel cooker – a
potential fire hazard (e.g. flying sparks) –
unless the cooker features a closed,
non-removable cover and all national
regulations are observed.
The smaller the gap between the
extractor hood and hotplates, the greater
the likelihood that droplets will form on the
underside of the extractor hood.
Additional information concerning gas
cookers:
When installing gas hotplates, comply
with the relevant national statutory
regulations (e.g. in Germany: Technische
Regeln Gasinstallation TRGI).
Always comply with the currently valid
regulations and installation instructions
supplied by the gas appliance
manufacturer.
Only one side of the extractor hood
may be installed next to a high-sided unit
or high wall. Gap at least 300 mm.
Minimum distance on gas hotplates
between the upper edge of the trivet
and lower edge of the extractor
hood: 650 mm, Fig. 1.
With automatic
cooker hoods: 700 mm, Fig. 1.
Prior to installation
Exhaust-air mode
The exhaust air is discharged upwards
through a ventilation shaft or directly
through the outside wall into the open.
D
Exhaust air must not be discharged via
a smoke or exhaust gas flue which is
already in use or via a shaft which is used
for ventilating rooms in which fireplaces are
located.
Discharge exhaust air in accordance
with official and statutory regulations
(e.g. national building regulations).
Discharge of air into smoke or exhaust air
flues which are not in use requires the con-
sent of a heating engineer.
D
If the extractor hood is operated in
exhaust-air mode at the same time as a
flue-type heater (e.g. gas, oil or solid-fuel
heater, instantaneous water heater, boiler),
ensure that there is an adequate air
supply which the heater requires for
combustion.
Safe operation is possible provided that the
partial vacuum in the room in which the
heater is installed does not exceed 4 Pa
(0.04 mbar).
This can be achieved if the combustion air
is able to flow through non-lockable
openings, e.g. in doors, windows and in
conjunction with an air supply/air-intake wall
box or by other technical procedures such
as reciprocal interlocking.
If the air intake is inadequate, there is a
risk of poisoning from combustion gases
which are drawn back into the room.
An air-intake/exhaust-air wall box by itself is
no guarantee that the limiting value will not
be exceeded.
Note: When assessing the overall
requirement, the combined ventilation
system for the entire household must be
taken into consideration. This rule does not
apply to the use of cooking appliances,
such as hobs and gas cookers.
The extractor hood can be used without
restriction in circulating air mode – with an
activated carbon filter.
For exhaust air mode a one-way flap
should be installed in the extractor hood
unless already installed in the exhaust air
pipe or wall box.
If a one-way flap is not enclosed with the
extractor hood, you purchase one from
your dealer.
If the exhaust air is conveyed through
the outside wall, a telescopic wall box
should be used.
