Functional Description; Recirculation Mode - Miele DA 249-4 Operating And Installation Instructions

Functional description

The hood offers two modes of
operation:
Air extraction
The air is drawn in and cleaned by the
decor panel and the grease filter and
directed outside.
The hood comes equipped with a
non-return flap. This 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 the decor
panel, grease filter and an active
charcoal filter. The filtered air is then
recirculated back into the kitchen
through a vent at the top of the hood's
chimney.
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".
