of device damage and the service life of the device may
be shortened.
Observe the replacement intervals (indicator light).
Note
The replacement intervals depends on the local water
hardness. Areas with hard water (e.g. III/IV) have a
higher replacement interval than areas with soft water
(e.g. I/II).
Indicator lamp at end of the run time
The "decalcification cartridge indicator light" indicates
when the decalcification cartridge has to be replaced:
 The indicator light flashes 2 hours before the run
time expires.
 The indicator light flashes more quickly 1 hour be-
fore the run time expires.
 Once the run time for the decalcification cartridge
has expired, the indicator light lights up constantly
and the device switches off automatically in order to
prevent device damage.
Inserting the decalcification cartridge
ATTENTION
Device damage
There is a risk of damage to the device if the used de-
calcification cartridge is re-used.
Work carefully in order to prevent mixing up the cartridg-
es.
Note
When steaming for the first time after removing and re-
inserting the decalcification cartridge, the steam jet may
be weak or irregular, and individual drops of water may
be expelled. The device requires a short running-in pe-
riod in which the decalcification cartridge fills with water.
The steam volume that is expelled increases constantly
until the maximum steam volume has been reached af-
ter approx. 30 seconds.
1. Press the Off switch.
The device has been switched off.
2. Remove the decalcification cartridge.
3. Insert the new decalcification cartridge.
4. Press the On switch.
The device is switched on.
5. Press and hold the RESET key for 4 seconds.
The "replace decalcification cartridge" indicator light
goes out and the run time for the decalcification car-
tridge starts again.
6. Allow the device to heat up.
7. Press and hold the steam lever for approximately 30
seconds to vent the decalcification cartridge.
Setting the water hardness
ATTENTION
Device damage due to calcification
Without a decalcification cartridge, the device may cal-
cify if the water hardness is set incorrectly.
Always work with a decalcification cartridge.
Set the device to the local water hardness.
Set the device to the current water hardness before us-
ing it in an area with a different water hardness (e.g. af-
ter a move).
Note
Your water board or municipal utilities authority can pro-
vide information on hardness of tap water.
The water hardness is set using the RESET key. The
water hardness setting is stored until a new setting (e.g.
after a move) is made. The device is set to the highest
water hardness (level IV) in the factory. The device indi-
cates the set water hardness with flash pulses.

Note
The anti-calcification effect of the decalcification car-
tridge is activated as soon as the device is filled with wa-
ter and put into operation. Lime in the water is absorbed
by the granulate in the decalcification cartridge. Addi-
tional descaling is not required.
Note
The granulate in the cartridge may change colour after
it comes into contact with water. This depends on the
mineral content in the water. This discolouration is
harmless and does not have a negative effect on the de-
vice, cleaning work or the functionality of the decalcifi-
cation cartridge.
Note
Do not pause for longer than 15 seconds when setting
as the device will otherwise be set automatically to the
last selected water hardness or the highest water hard-
ness set during initial start-up.
1. Connect the mains plug.
2. Make sure that the device is switched off.
3. Press the RESET key and hold it while the device is
switched on.
Illustration G
After approximately 2 seconds, the indicator light
flashes and signals the current water hardness set-
ting with the number of pulses.
4. Press the RESET key repeatedly to change the wa-
ter hardness level.
Note
When the RESET key is pressed, the flash pulse for
the water hardness level is not indicated.
5. Release the RESET key.
The flash pulse for the set water hardness is indicat-
ed.
6. Repeat the process as necessary until the desired
water hardness level has been achieved.
7. Press and hold the RESET key for 3 seconds to
save the setting for the water hardness level.
The indicator light for the water hardness lights up.
Care of accessories
(Accessories - depending on scope of delivery)
Note
The floor cleaning cloth and the cover for the manual
nozzle have been washed beforehand and can be used
immediately for working with the appliance. The micro
fibre cloths are not suitable for dryer.
Note
When washing the cloths, observe the instructions on
the washing tag. Do not use any liquid softeners as this
will affect the ability of the cloths to pick up dirt.
1. Wash the floor cleaning cloths and covers at a max.
temperature of 60 °C in the washing machine.
