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.
Illustration R
The indicator light flashes more quickly 1 hour be-
fore the run time expires.
The indicator light and the LED strip on the device
light up when the run time of the decalcification car-
tridge has expired. The floor covering symbols on
the handle do not light up. The pump switches off
automatically (no water steam) to prevent damage
to the device.
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.
Installation information
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.
Note
Removing the water reservoir makes it easier to remove
and install the decalcification cartridge.
1. Press the OFF switch.
The device is switched off.
2. Remove the reservoir cover.
3. Remove the decalcification cartridge.
4. Insert the new decalcification cartridge and press it
firmly into place.
5. Press the On switch.
The device is switched on.
6. Press and hold the RESET button for 4 seconds.
The "replace decalcification cartridge" indicator light
goes out and the run time for the decalcification car-
tridge starts again.

7. Allow the device to heat up.
8. 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 button. 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.
Water hardness levels and flash pulses
Note
The anti-calcification effect of the decalcification car-
tridge is activated as soon as the reservoir is filled with
water and the device is put into operation. Lime in the
water is absorbed by the granulate in the decalcification
cartridge. Additional descaling is not required.
Note
The granulate in the cartridge can discolour on contact
with water due to the mineral content in the water, which
is no cause for concern and has no negative effects on
the device, cleaning work or the functionality of the car-
tridge.
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. Hold the RESET button pressed and switch on the
device.
Illustration Q
After approximately 2 seconds, the indicator light
flashes and signals the current water hardness set-
ting with the number of pulses.
4. Release the RESET key.
The device is set to water hardness level IV at the
factory and the indicator light therefore flashes 4
times in succession.
5. You can cycle between the different water hardness
levels by pressing the RESET button repeatedly un-
til the desired water hardness level is reached.
6. Once the desired water hardness level has been
reached, press and hold the RESET button for 3
seconds to store the selected water hardness level.
The indicator light for the water hardness lights up to
confirm saving.
Care of accessories
(Accessories - depending on scope of delivery)
Note
The micro fibre cloths are not suitable for dryer.
Note
Observe the instructions on the washing tag when
washing the cloths. 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 in a washing machine
at a max. temperature of 60 °C.
