ervoir.

to the initial start-up to bleed the water pipe
system.
With automatic fill of fresh water reser-
voir (option)
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.

nect the hose from the appliance.
Metering device (option)
Detergent is added to the fresh water on
the way to the cleaning head with the help
of a dosaging device.

Note:
The dosing unit can be used to add 3% de-
tergent at maximum. With higher dosage
the detergent must be put into the fresh wa-
ter tank.
ATTENTION
Risk of clogging due to dried detergent when
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
water at the programme selector switch. Set
the water quantity to the highest value, set
