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.

9.7.2 Installation variants A and B
for recirculation appliances
There are 2 installation variants for recirculation
appliances: A and B

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.
