Silencer - Miele DA 2906 Operating And Installation Instructions

Installation
– The exhaust ducting must not be
kinked or compressed.
– Ensure that all connections are
strong and airtight.
Remember that any constriction of
the air flow will reduce extraction
performance and increase operating
noise.
 If the exhaust is ducted through an
outside wall, a telescopic wall vent or
a roof vent (available as an optional
accessory) is recommended.
 If the exhaust air is to be ducted into
a flue, the ducting must be directed in
the flow direction of the flue.
 Where ducting is horizontal, it must
be laid to slope away at at least 1 cm
per metre. This is to ensure that
condensate cannot drain back into
the cooker hood.
 If the exhaust ducting is to run
through rooms, ceiling space etc.
there may be great variations in
temperature between the different
areas. The problem of condensation
will need to be addressed. The
exhaust ducting will need to be
suitably insulated.

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 .
