Connection for air extraction
34
If the exhaust ducting is to run
through rooms, ceiling space etc.
where 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.
Air 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 .
