Care and maintenance

Emptying the water tank
ATTENTION
If the device is not used for a longer period of time (ap-
prox. 2 months), please empty the water tank. This
avoids decomposition of the water.
 Press the OFF switch to turn off the appliance.
 Disconnect the mains plug from the socket.
 Remove the accessories from the accessory com-
partments.
 Remove the cartridge from the device.
Illustration
 Completely empty the water tank to remove exist-
ing water.
Replacement descaler cartridge
ATTENTION
The replacement intervals of the cartridge (display indi-
cator light) must be complied with; otherwise the service
life of the device is reduced.
If the cartridge is not replaced in the indicated intervals,
irreparable damage can be caused on the device.
Note
 The replacement intervals depend on the local wa-
ter hardness. Areas with harder water (e.g. III/IV)
have a shorter replacement interval than areas with
softer water (e.g. I/II).
Indicator light display at the end of the operating
time
The necessary cartridge replacement is indicated via
the indicator light "Replacement cartridge" by the follow-
ing actions:
 Two hours before the end of the operating time the
necessary replacement is indicated by flashing.
 One hour before the end of the operating time the
indicator light flashes faster.
 If the operating time of the cartridge is completely
depleted, the indicator light "Replacement car-
tridge" is continuously on and the device switches
itself off in order to prevent damage to the device.
Insert new descaler cartridge.
 Press the OFF switch to turn off the appliance.
 Remove the cartridge from the device.
 Insert new cartridge into the device.
 Press the ON switch to turn on the appliance.
 Hold down the RESET button for 4 seconds.
Then the indicator light "Replacement descaler car-
tridge" goes out and the operating time of the car-
tridge starts again.
 Allow the device to warm up.
 Then hold down the steam lever for approx. 30 sec-
onds to bleed the cartridge.
Note
During the first steaming after removal and reinserting
the cartridge the blast of steam can still be a little weak.
The device requires a short break-in period, as the car-
tridge has to be filled with water first. This is why the
steam discharge is unsteady at first and single water
drops may exit. The amount of escaping steam increas-
es continuously until the maximum amount is reached
after approx. 30 seconds.
ATTENTION
When replacing the cartridge, ensure that there is no
confusion and the old cartridge is not reinserted.
Care of the Accessories
Note
The floor cleaning cloth and the cloth cover have been
pre-washed and can be used immediately for working
with the steam cleaner.
 You can wash dirty floorcloths and cloth covers in
the washing machine at 60°C. Do not use a liquid
softener as this would affect the ability of the cloths
to pick up dirt. You may tumble dry the terry cloths.
The microfiber cloths are not suitable for the tum-
ble.
