distance of approximately 20 cm until

Danger
Always disconnect the mains plug and al-
low the steam cleaner to cool down before
performing any maintenance work.
Rinse the steam cleaner boiler at the latest
after 10 boiler fillings.

Fill the boiler with water and shake it
strongly. This dissolves lime scaling re-
siding on the boiler bottom.
 Empty water out.
Note: If you always use usual commercial
distilled water it is not necessary to descale
the boiler.
As limescale builds up on the boiler walls,
we recommend to descale the boiler in the
following intervals (RF=reservoir fillings):
Note: Please contact your Conservancy
Board or the local water supply company to
inquire about the hardness of your water.
 Disconnect the mains plug from the
socket.
 Allow device to cool down.
 Remove the safety cap from the device.
 Completely empty the steam boiler to
remove existing water (see fig. ).

Warning
Only use products approved by KÄRCHER
to exclude any damages of the appliance.

Use the KÄRCHER decalcifier sticks
(order no. 6.295-206) to decalcify the
water. Please follow the dosing instruc-
tions on the packaging while using the
decalcifying solution.
Caution
Use caution when filling and emptying the
steam cleaner. The descaling solution can
have an aggressive effect on delicate sur-
faces.

Pour the descaling solution into the boil-
er and allow it to react for approximately
8 hours.
ṇ
Warning
Do not screw the safety lock on the appli-
ance during the decalcifying.
Do not use the steam cleaner as long as
there is decalcifying agent in the boiler.

Completely empty the descaling solu-
tion after 8 hours. A small amount of the
solution will remain in the boiler. There-
fore, you should rinse the boiler two to
three times with cold water to remove
any residues of the descaler.
 Completely empty the steam boiler to
remove existing water (see fig. ).
