WARNING
Do not screw the steam boiler cap on the 
appliance during the descaling. Do not use 
the steam cleaner as long as there is des-
caling agent in the boiler.
Î
Empty the descaling solution after 8 
hours. A small amount of the solution 
will remain in the boiler. Therefore, you 
should rinse the boiler two to three 
times with cold water to remove any 
residues of the descaler.

again.
Allow the accessory parts to dry completely 
before storing them.

Do not place the floor nozzle (H1), the 
manual nozzle (E1), and the round 
brush (D2) onto the bristles during the 
cooling and drying process to avoid a 
deformation of the bristles.
Note: The floorcloth and the terry cloth cov-
er have been pre-washed and can be used 
immediately for working with the steam 
cleaner.
Î
You can wash dirty floorcloths and terry 
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 
cloths.
