Notes
When drying is in progress,
condensed water is pumped into the
condensed water container through
the drain hose which is located at the
back of the dryer.
The condensed water can also be
drained off directly through the drain
hose if the tumble dryer is installed near
a sink, drain outlet etc. so that the
condensed water container does not
have to be emptied.
Drain hose length: 1.60 m
Maximum delivery head: 1.50 m
Maximum drain hose length: 4.00 m
The following optional accessories
are available:
– an extension hose,
– a non-return valve kit for connection
to an external water outlet. The kit
includes an extension hose.

There is a risk of back-flow into
the dryer if a non-return valve is not
fitted.
Back-flow 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 for
external condensed water drainage.
Maximum delivery head with non-return
valve fitted: 1.00 m
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.

The non-return valve has to be
fitted with the arrow pointing in the
direction of flow.
Otherwise water will not drain out of
the appliance.
