Miele DA 3180 EN - Manual (Page 7)

The ventilation hood offers two modes
of operation:
Air extraction
The air is drawn in and cleaned by the
grease filters and directed outside.
The hood comes equipped with a
non-return flap. The flap automatically
closes when the hood is turned off so
that no exchange of outside air and
room air can occur. When the hood is
turned on, the air pressure of the
exhaust fan automatically opens the
flap blowing the inside air and cooking
odors outside.
Recirculation mode
Air is drawn through the grease filters
and an active charcoal filter. The
filtered air is then recirculated back into
the kitchen.
The recirculation mode requires an
install kit and charcoal filter which are
optional accessories.
Before using the hood in
recirculation mode, ensure that the
active charcoal filter is in place, see
"Cleaning and care".
