Miele DA 3160 EXT Operating And Installation Instructions page 30

If site conditions are not suitable for the
cooker hood to be used with air
extraction, the appliance must be set
up for recirculation.
For this, we recommend using the
conversion kit available from your Miele
dealer or the Miele Spare Parts Dept
(see "Technical data").
You will also need a charcoal filter (see
"Technical data").
^ Attach the ventilation ducting to the
underside of exhaust grille.
^ Then feed the ducting down into the
housing unit through the opening at
the top.
^ Secure the ducting over the exhaust
socket on the cooker hood using a
hose clip.
A non-return flap is not used in
recirculation mode.

^ Screw the exhaust grille to the top of
the unit.
When fitting the exhaust grille make
sure that the slats in the grille point
towards the centre of the room and
not directly towards a wall or the
ceiling.
^ Fit the charcoal filter (see "Cleaning
and care").
Refer to the notes in "Electrical
connection" and "Warning and
Safety instructions" before
connecting to the electricity supply.
^ For appliances connected to an
external motor (EXT models):
Connect the cooker hood to the
external motor using the connecting
cable and the 6-pole plug connector.
^ Separate fitting instructions are
supplied with the external motor.
