10.2 Maintenance
The Wasi-Steam Classic II should, depending on frequency of use, but at least twice a
year, be decalcified in accordance with the following instructions. Depending on water
hardness a more frequent decalcification could be required. Operation with distilled /
softened water is possible and is recommended. As a basic principle, the unit must always
be kept clean.
