Detergent is added to the fresh water on 

the way to the cleaning head with the help 

of a dosaging device.





Insert the suction hose of the dosaging 

equipment into the bottle.

Note

The metering device can be used to add

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
