How The Vapour Extraction Works - Miele KMDA 7633 FR Operating And Installation Instructions

How the vapour extraction works

The exhaust air drawn into the cooker
hood must not be routed into the base
unit. This will damage the unit.
Extraction mode
The air drawn in is cleaned by the
grease filter and directed outside
through a ventilation gap. The
necessary accessories are available
from Miele.
Recirculation mode
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 a charcoal filter. The
cleaned air is then recirculated back
into the kitchen. The necessary
accessories are available from Miele.
32
Operating hours counter
The number of hours that the cooker
hood 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
changed. Further information about
cleaning and changing the filters and
resetting the operating hours counter
can be found under "Cleaning and
care".
The instruction manual supplied with
the recirculation box states that the
operating hours counter for the
charcoal filter needs to be activated.
This is not necessary here.
The charcoal filter system  also
appears when the appliance is
operated using extraction mode.
