AEG 302D - Manual (Page 9)

In this mode the fumes filter through an active carbon filter
(optional extra) and are returned into the room. ^
To fit the carbon filter remove the grille C by turning locks D and
pull it out downwards (fig. 3). Fit the filter in the seat at the front and
fasten it at the back with the two hooks E (fig. 4). The cover F (fig.
5) must be fitted over the hole B (fig. 1) fixing it with the special
screw provided. This cover deflects the air forwards avoiding
soilage of the rear wall.
Important:
In the extraction mode the exhaust air must not be introduced into
a smoke flue or exhaust gas chimney.Introduction of the exhaust
air into a shaft used for ventilation of the installation spaces of
firerooms is not permitted.
If the exhaust air is introduced into a operational smoke flue or
exhaust gas chimney, it is advisable to seek the advice of a
competent chimney-sweep. The official exhaust air guidance
regulations are to be complied with.
During operation in the extraction mode, an adequate air opening
of approximately the same size as the exhaust air opening should
be ensured.
Recirculation
mode
Notes prior to
installation
According to the Provincial Building Regulations, the joint operation
of fume extractor hoods and chimney-linked fireplaces, such as
coal or oil-fired ovens and gas heaters, in the same space is
subject to specific restrictions. In such spaces, the Fireplace
Regulations only allow an underpressure of max. 0.04 mbar. The
safe joint operation of chimney-linked appliances and fume
extractor hoods is only guaranteed if space and/or dwelling
(space/air interaction) are externally vented by a suitable supply
air opening of around 500-600cm2 and an underpressure thereby
avoided when the cooker hood is running. In doubtful cases,
please seek the advice and consent of a competent chimney­
sweep or the local building authorities.
In spaces without a fireplace, the rule is: “Supply an air opening
as large as the exhaust air opening”, the efficiency of the hood in
the extraction mode may be impaired by a greater opening.
Operation of the hood in the recirculation mode in such
circumstances is safe and is not subject to the regulations above.
When installed, the minimum distance from the hob to the
lower edge of the cooker hood must be 65cm for electric hobs
or 75cm in the case of gas or mixed fuel hobs
