6.3 Herkules XL S120 Vapor: descaling the
vaporiser
Lime deposits can impact the ability of the vaporiser to function properly.
If water with lime content of more than 1.3 millimole of calcium oxide per
litre (hardness class I or hardness levels 1–7 in Germany) is used, the unit
typically operates properly and requires descaling on an as-needed basis
only. The unit must be regularly descaled if water with a higher lime con-
tent is used. The higher the lime content in the water used, the more often
the vaporiser must be descaled.
Necessary steps:
Material:
Descaler for household appliances
Container
Short piece of hose, if needed

the manufacturer's specifications.
