Operating mode
Gas pressure spring
The height-adjustable washbasin element is operated without electronics and functions with the help of a gas pressure spring.
The gas pressure spring guarantees continuous adjustment of the washbasin height within a 20 cm range.
INFO!
Further information can be found in the instruction for use of the gas pressure spring.
CAUTION!
Risk of crushing
The cover plate shifts in parallel with the wall surface during the height adjustment. Due to this, there is the risk of crushing in the areas above and below the cover plate.
Keep your hands away from the dangerous areas.
Lowering the washbasin
When the actuating button is pressed and gentle pressure is applied to the washbasin, the sanitary ware is lowered by a maximum of 20 cm.
Lifting the washbasin
When the actuating button is pressed and no pressure applied, the washbasin is raised by a maximum of 20 cm by the gas pressure spring. If necessary, apply some manual help in the case of heavy washbasin ceramics.
Compatible components
The washbasin element can only be used for WB ceramics with a total weight including fitting of 15‑21 kg.
The cover plate 8570.45 is required for the detailed installation.
