Connecting water supply
CWe recommend attaching a
filter on the house/apartment
supply water inlet to protect the
machine from damages that may
arise from impurities (sand, dirt,
rust, etc.) coming from the urban
water supply system or from
your own water system as well
as to prevent complaints such as
yellowing or sludge accumulation
at the end of washing.

Installation

25°C ( 60°C for products equipped
with WaterProtect+; please refer
toWaterProtect+ section )
•Do not use old or used water inlet hose
on the new product. Use the new water
inlet hose supplied with the product.
•Connect the water inlet hose directly
to the water tap. Pressure coming from
the tap should be minimum 0.3 and
maximum 10 bars. If the water pressure
exceeds 10 bars, a pressure relief valve
should be installed in between.
•Open the taps completely after making
the connections to check for water leaks.
CUse a screw-on hose connector
to connect the water inlet hose
to a water tap with a ¾ inch
external thread. If required, use a
filter insert to filter deposits from
the pipes.
AFor your safety, close the water
inlet tap completely after the
washing programme is over.
Connection to the drain
Water discharge hose can directly be
connected to the drain hole or sink’s
drainage. The length of this connection must
be min. 50 cm and max. 100 cm from the
floor. A discharge hose longer than 4 meters
causes dirty washing.
Attach the water discharge hose to the
drainpipe without bending it. Tightly fix the
water discharge hose to the drainpipe in
order to prevent any dislocation of the water
discharge hose during operation of the
product.
