Miele DA 337 I - Manual (Page 10)

Description of the functions
The hood works
. . . by air extraction:
The air is drawn in, cleaned by an exter-
nal filter and then passed through an in-
ternal filter before being directed out-
side.
The hood has a non-return flap , (see
"Installation").
This flap is closed when the hood is
off. No exchange of room air and out-
side air can take place. When the
hood is turned on the non-return flap
opens for the cooking odors to be
blown outside.
. . . by air recirculaton:
The air is drawn in and cleaned first by
the external filter, then by the internal fil-
ter before passing through an active
charcoal filter. The cleaned air is then
recirculated back into the kitchen
through a vent in the top of the hood.
Before using the hood for the first
time in recirculation mode, make
sure that the active charcoal filter is
in place. See Section on "Cleaning
and care".
