3.3 Cleaning and maintenance
Cleaning work may only be carried out by specialist trade professionals
or qualified experts.
In consideration of the mechanical, chemical and physical conditions,
the concealed cistern is constantly laden.
For this reason, the components must be cleaned, as required, and the
drain and filling valve seals renewed.
In areas or regions with hard water due to calcium or magnesium salts,
there is the risk of limescale deposits developing on the inlet and drain
valves.
The valves may have to be replaced, depending on the extent of
deposits.

Disposal
Separate the product and packaging materials (e. g. paper, metal,
plastic or non-ferrous metals) and dispose of in accordance with valid
