Note:
It is recommended to use a hose that is
equipped with an Aquastop coupling on the
appliance side. This minimises the spout-
ing of water when the hose is disconnected
after the filling process.
Connect the hose to the automatic fill-
ing system and open the water supply
(max. 60 °C, max. 5 bars).
Wait briefly - the automatic filling sys-
tem will interrupt the water supply when
the tank is full.
Shut off the water supply and discon-
nect the hose from the appliance.

Detergent is added to the fresh water on
the way to the cleaning head with the help
of a dosaging device.

the detergent is added to the fresh water
tank of the Dose version. The flow meter of
the dosing equipment can agglutinate on ac-
count of drying detergent and hamper the
functioning of the dosing equipment. Subse-
quently rinse the fresh water tank and the
appliance with clear water. For rinsing, se-
lect cleaning programme with application of
