Silencer
To achieve even further reductions in
noise levels, a special silencer (optional
accessory) can be fitted in the ducting
system.
Extraction mode
The silencer not only reduces noise
from the motor outside the house, but
also sounds from outside (e.g. traffic
noise). For this reason the silencer must
be positioned as close as possible to
the ducting exit

.
Extraction mode 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 socket on the
cooker 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.
