Air evacuation
Installing the air exhaust system
If several tumble dryers are connected to an
air exhaust system, a non-return fl ap valve (R)
has to be installed for each dryer. Installing a
non-return fl ap valve will prevent air backfl ow
into the dryer.
To install the non-return fl ap valve, some extra
equipment is required:
Exhaust connection (1), non-return fl ap valve
(2), adapter piece (3), fl exible exhaust duct (4)
Non-return fl ap valve and the adapter piece
are not supplied with the appliance and should
be purchased extra at a specialized store.
! Please ensure the non-return fl ap valve is
cleaned regularly.
Up to fi ve tumble dryers can be connected to
an air exhaust system.
If between two and fi ve tumble dryers are
connected to an air exhaust system, the
diameter of the exhaust duct (D) should be
increased:
2–3 dryers → D × 1.25
4–5 dryers → D × 1.5
