VENTILATION CONTROL
The house extraction fan serves as the mechanical air
extraction unit in the apartment, allowing the resident to
adjust the ventilation efficiency. Adjustments are made,
based on the need, via the ventilation control panel.
USING THE UNIT
Position of the damper
When turned to the left, the damper is in the closed
position: In normal circumstances, the damper must be
closed,
which boosts the extract air flow from other premises.
When turned to the right, the damper is in the open
position
:
used when the extract air flow needs to be boosted,
e.g., in the following situations:
• when the cooker top or the oven is used for cooking
• when the load in the kitchen is exceptional e.g. due to
the use of strong detergents or the presence of a large
number of people.
The extraction can be boosted, where required, by using
the ventilation control panel.

1. Away mode (position 1).
The ventilation efficiency can be temporarily reduced
when the apartment is unoccupied.
2. Normal mode (position 2 or 3)
Ventilation must be constant to ensure that impurities
related to normal living are removed from the indoor air.
3. Boost mode (positions 3-4)
Cooking, sauna, bathing, drying of clothes, excessive
heat, and other similar situations can require that
ventilation be increased from the standard setting. In
such a situation, ventilation must be increased. This
is done by boosting the ventilation either in general
or space-specifically. For example, the damper of the
cooker hood is kept open during cooking but is closed
or in the minimum position at other times.
MAINTENANCE
Keep the fan clean. Wipe outer surfaces regularly with water
containing a small amount of a mild detergent. Clean off any
grease stains immediately. Do not use abrasive or corrosive
detergents or tools.
Keep the grease filter clean to ensure an adequate extract air
flow. The grease filter must be washed with warm water and
detergent at least 1-2 times a month.
Removing and mounting the grease
filter
• Open the quick connectors of the bottom plate of the
cooker hood by turning (figure 1).
• Turn the bottom plate down.
• Remove the grease filter from its holder (figure 2).

CAUTION
• Neglecting the cleaning of the grease filter
can cause a fire hazard.
• The outer surfaces of the hood can
become hot when the cooker or the oven is
turned on.
• Flaming is forbidden underneath the
cooker hood.
• Always follow the instructions provided on
adjusting the efficiency of ventilation.
• Enable a sufficient supply air flow into the
room if the cooker hood and non-electric
devices are used simultaneously.
WARNING
If the ventilation of the apartment is turned
off, the entry of fresh replacement air into
the apartment and the extraction of used air
from the apartment are prevented. Impurities,
such as carbon dioxide, humidity, smells,
formaldehyde, dust, and radon, that come from
people, structures, and the soil will quickly
contaminate the room air and are harmful to
the health of people. Excessive humidity may
damage the structures of the building and result
in mould and fungal growth. For this reason,
building regulations require that ventilation be
turned on at all times and that its efficiency is
adjusted based on the needs of the user.
WARNING
The unit is not intended for use by children
under 8 or by persons with reduced sensory,
physical or mental capabilities, or whose lack of
knowledge and experience do not ensure safe
operation of the unit. Such persons can use
the unit under supervision, or by following the
instructions of someone who is responsible for
their safety. Do not let children play with the unit
or to clean or maintain it without supervision.
