Main venting duct
We recommend that when several dry-
ers are being installed each dryer
should be fitted with one non-return flap
installed directly on the main venting
duct (
R
, upper picture). Extra Miele
equipment is required for this purpose.
When up to five dryers are being in-
stalled, the pipe diameter
D
must be in-
creased according to Table III.
