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
≥ 500cm² for each cooktop extractor.

Installation variants (A and B)
for recirculation appliances
There are 2 installation variants for recirculation appliances:
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.
