Miele DA 220-4, Operating And Installation Instructions

Page: 7 / 36

The ventilation hood works by air
extraction . The air is drawn in and
cleaned by 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.
