Gas pressure spring
Product information
Prevista Dry washbasin element with individually adjustable ceramic height 7 from 38

The gas pressure spring guarantees continuous adjustment of the
washbasin height within a 20 cm range.
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.
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.
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.
