Safety instructions
For connections and functions
■ Maintenance and repair work may only be carried out by an authorised
technician in accordance with the applicable safety regulations. Work which
has been performed improperly can endanger your safety.
■ Extraction appliances must not be connected to smoke or fume chimneys
or to shafts used for ventilating rooms where stoves have been installed.
Before extracting fumes into a smoke or fume chimney which is not in use,
please obtain approval from your local chimney sweep. When extracting
fumes, please observe the official regulations.
■ The minimum distance between the cooker hood and the cooker is
650 mm.
■ For cleaning and maintenance work the hood must be deactivated by
switching off the household fuse.
For operating your cooker hood
■ The fat filter must be cleaned regularly. There is a danger of fire if the ap-
pliance is used with a saturated fat filter!
■ Only use the hood when the fat filters have been installed.
■ Never flambé dishes under the cooker hood!
■ Ignited rings of gas cookers and gas hobs must always be covered by pots
or pans.
■ Keep an eye on deep-fat fryers while in operation. Fat and oil which ignites
due to overheating can set fire to the cooker hood.
■ The fume trap should not bear excessive or one-sided loads. If the glass
breaks, there may be a danger of injury from falling pieces of glass!
For operating the hood with stoves and
heating appliances with a naked flame
This relates, for example, to gas, oil or coal-fired heating appliances,
continuous flow heaters and hot water tanks: If the cooker hood is operated
in extraction mode, such appliances may no longer have sufficient air required
for combustion and there is a danger of intoxication or explosion!
Operation is perfectly safe if the cooker hood and the stove are being used
simultaneously in rooms where a negative pressure of 0.04 mbar is not
exceeded. This ensures that the fumes from the stove are not sucked back
into the room.
This can be achieved if there are non-airtight openings in windows and doors,
ventilation wall boxes (supplying/extracting air) or other technical
devices, e. g. interlock devices so that a sufficient supply of combustion air
can flow back into the room.
When assessing the ventilation requirements, the ventilation system of your
entire home must always be taken into account. This means, for example, the
above regulations for operating cooking appliances (e.g. hobs and gas cookers)
are not applied. If in doubt, please consult your local chimney sweep.
■ If the cooker hood is only used in recirculation mode - with activated
charcoal filter - there are no restrictions on operation.
Example of how to use the cooker hood and the stove in
complete safety:
■ A switch at the window prevents the cooker hood from being operated when
the window is closed.
General advice for use
Remember that the ventilation problem in the kitchen is often not solved
merely by installing a cooker hood. For optimum effect and maximum
ventilation efficiency the cooker hood requires a sufficient supply of air from
the correct sources. Disappointing performance and the development of loud
noises are almost always the result of planning or operating errors.
Example:
■ Insufficient supply of fresh air
Result: The speed of the ventilation motor increases, the air capacity
decreases and the noises become louder.
Solution: Ensure that there is an adequate supply of fresh air through structural measures or by opening the window when the cooker hood is in operation.
■ Saturated filters
Result: The air capacity of the cooker hood decreases and the fumes are
insufficiently cleaned.
Solution: Clean the filters regularly before the air capacity decreases.
