–
The appliance drainage sy stem is
fitted with a non-return valve, which
prevents dirty water from flowing
back into the dishwasher via the
drain hose.
–
The dishwasher is supplied with
approx . 1.5 m of flex ible drain hose
with an internal diameter of 22 mm.
–
The drain hose can be ex tended
using a connection piece to attach a
further length of hose.
The drainage length must not be
longer than 4 m, and the delivery
head must not ex ceed 1 m.
– If the hose is to be directly fitted to
the drainage outlet on site, use the
hose clip supplied (see installation
diagram).
– The hose can be directed to the left
or the right of the appliance.
– The on-site connector for the drain
hose can be adapted to different
widths of hose. If the connector
protrudes too far into the drain hose,
it will need to be shortened.
O therwise the drain hose may
become blocked.
–
The drain hose must not be
shortened.
,
Make sure that there are no
kinks in the hose, and that it is not
sq uashed or stretched.
V enting th e d rainag e sy stem
If the on-site drain connection is
situated lower than the guide path for
