Miele Novotronic T 510 Operating Instructions Manual page 27

Installing several machines:
We recommend that when several ma-
chines are being installed each ma-
chine should be fitted with a non-return
flap (available from a good builder's
merchant). This will prevent odours
being transferred and the build up of
condensation in the machines which
are not in use.
For installation where up to 5 machines
are connected to a shared system the
pipe diameter (D) must be increased.
the factor to increase by is given in
Table III.
