Installation conditions requiring a
non-return valve
There is a risk of backflow into
the dryer if a non-return valve is not
fitted.
Backflow could damage the dryer
and also the room in which it is
located.
Certain installation conditions, such
as those described below, require
the fitting of a non-return valve.
Installation conditions requiring the
fitting of a non-return valve:
– Drainage into a sink or floor gully
where the end of the hose is
immersed in water.
– Connection to a sink drain outlet.
– Connection to a drainage system
already in use by another appliance,
e.g. a dishwasher or washing
machine.
Maximum delivery head with non-return
valve: 1.00 m
Example: Connection to a sink drain
outlet
The drain hose with non-return valve
fitted can be connected directly to a
suitable sink drain outlet.
Remove the following from the back
of the dryer at the top: Adapter 1 and
hose clip 3 behind it.
