Working without automatic detergent
dosing
While cleaning floors in hygiene-related ar-
eas (such as hospitals, supermarkets) and
for thoroughly cleaning very dirty floors.
Open the cover of the fresh water reser-
voir.
Fill up fresh water (maximum 60 °C) un-
til the lower edge of filling nozzle.
Add detergent. Follow dosing instruc-
tions for detergent.
Close the cover of the fresh water reser-
voir.
Dosing equipment for detergent (op-
tional)
Detergent is added to the fresh water on the
way to the cleaning head with the help of a
dosaging device.
Warning
Risk of damage to the dosing equipment.
Do not add detergent to the fresh water res-
ervoir.
Note
The dosing equipment can be used to add
3% of detergent at maximum.
Place the detergent bottle in the holder
in the front on the fresh water reservoir.
Close the bottle lid.
Insert the suction hose of the dosing
equipment into the bottle. Ensure that
the sieve of the suction hose is lying at
the base of the bottle.
Close the bottle using the lid of the dos-
ing equipment.
You can check the filling level of the bottle
through a vertical view window.
If the filling level of the detergent reaches
the bottom of the bottle:
Add detergent or replace detergent bot-
tle.
Warning
If you want to change the detergent type,
then first rinse the suction hose thoroughly
using fresh water (for 60 seconds using
maximum quantity of water and 3% dosing)
in order to avoid chemical reactions.
Note
When the detergent bottle is fully emptied,
then operate the dosing equipment for 60
seconds with maximum quantity of water
and 3% dosing so that the suction hose is
again fully filled up with the detergent.
Note
While refilling or replacing the detergent
bottle, hang in the suction hose of the dos-
ing equipment into the opened fresh water
tank so that no detergent drops fall on the
floor.
Note
If the fresh water tank is empty, then the
function of adding detergent gets deactivat-
ed. The cleaning head continues to work
without the addition of any liquid.
Note
As soon as the detergent pump starts run-
ning, this is indicated through a blinking "C"
in the display.
