Filling system (optional)

tion neck on the filling system.
 Open the water supply.
Once the maximum fill level is reached,
the built-in floater valve will stop the wa-
ter inflow.
 Shut off water supply.

Metering system (only Dose model)
Detergent is added to the fresh water on
the way to the cleaning head with the help
of a dosaging device.
 Place the detergent bottle into the de-
vice.
 Close the bottle lid.
 Insert the suction hose of the dosaging
equipment into the bottle.
Note
The metering device can be used to add
3% of detergent at maximum. In case of a
higher dose the detergent must be poured
into the fresh water tank.
Caution
Danger of plug-up by dried detergent when
the detergent is added to a fresh water tank
made by Dose. The flow meter of the dos-
ing equipment can stick on account of dry-
ing detergent and hamper the functioning
of the dosing equipment. Always rinse at
the end the fresh water tank and the appli-
ance with clear water. To rinse, open the
regulating knob fully, set the detergent me-
tering setting to 0% and set the cleaning
program with water at the programme se-
lection switch.
Note
The appliance is equipped with a fresh wa-
ter level display. If the fresh water tank is
empty, then the function of adding deter-
gent gets deactivated. The cleaning head
continues to work without the addition of
any liquid.
