How The Extractor Works - Miele KMDA 7774 Operating And Installation Instructions

The extractor can be operated in one of
the following ways:
Air extraction mode
The air is drawn in and cleaned by the
grease filter and directed outside.
Recirculation mode
(DUU 1000(-1) conversion kit required)
The air is drawn in and cleaned by the
grease filter. The air is then directed into
the recirculation box where it is also
cleaned by the charcoal filter. The
cleaned air is then recirculated back
into the kitchen.

How the extractor works

Operating hours counter
The number of hours that the extractor
has been used for is stored in memory.
When the grease filter symbol  or the
charcoal filter symbol  lights up, the
operating hours counters are signalling
that the filters need to be cleaned or
replaced. Further information about
cleaning and replacing the filters and
resetting the operating hours counters
can be found under "Cleaning and
care".
The operating and installation
instructions supplied with the
recirculation box state that the
operating hours counter for the
charcoal filter needs to be activated.
This is not necessary here.
The charcoal filter symbol  also
appears when the appliance is
operated using extraction mode.
