Installing the appliance
in recirculation mode
9.7.1
Recirculation of air from the
kitchen unit
In the case of recirculation systems, a return flow
aperture must be provided in the kitchen unit to guide
the clean recirculated air out of the unit and back into
the room. The return flow aperture can be created
above a shortened plinth. A slatted plinth with at least
the minimum opening cross-section can also be used.
u
Decrease the height of the plinth panel or create
corresponding openings in the plinth.
u
The cross-section of the return flow aperture must be
≥ 500cm² for each cooktop extractor.

Installation variants (A and B)
for recirculation appliances
There are 2 installation variants for recirculation
appliances: A and B
A: floor unit with continuous back panel
The recirculated air is guided through the connection
with the back wall of the air purification box directly
behind the back panel of the unit. The recirculated air
goes back in to the room through the return flow
aperture.
For installation purposes, this means that:
T
No false floor is necessary below the cooktop.
T
There must be a cut-out in the back panel.
B: floor unit with false floor under the cooktop
The recirculated air is blown into the free space
between the worktop and the false floor (the air
purification box does not connect with the back panel).
The recirculated air goes behind the back panel of the
unit and through the return flow aperture back into the
room.
For installation purposes, this means that:
T
a false floor is necessary below the cooktop.
T
There does not need to be a cut-out in the back
panel of the unit.
9.7.3
Preparing the kitchen unit for
installation variant A
T
Cross bars on the kitchen unit in the area of the
worktop cut-out may need to be removed.
T
In the case of thin worktops, there must be a
sufficiently rigid support plate on the unit.
T
The floor unit must have a continuous back panel so
that the recirculated air is not directed into the front
furniture body compartment.
T
There must be a cut-out in the back panel.
T
A minimum clearance of 25mm between the back
panel of the unit and an adjacent kitchen unit or
room wall must be observed for the return flow of the
recirculation air.
T
No false floor is necessary below the cooktop. If
cable protection (false floor) is planned, the following
must be taken into account:
T
it must be fitted in such a way that it can be
removed for maintenance work.
T
To ensure sufficient cooktop ventilation, a
minimum distance of 15mm to the bottom edge
of the cooktop is to be observed.
T
The drawers and/or shelves in the floor unit must be
removable.
