Connection for air extraction
Recirculation mode
The silencer needs to be positioned
between the exhaust connection and
the directional unit . Ensure there is
adequate space in the tower for fitting
it.
Air extraction with external motor
To minimise noise from the motor in the
kitchen, the silencer should be
positioned in front of the external motor
 if possible, or, if the ducting is long,
above the exhaust connection inside
the hood . In the case of an external
motor located inside the house, fitting a
silencer behind the external motor 
reduces the noise of the motor outside
the house.
