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 hands away from the dangerous areas.
When the actuating button is pressed and there is the light load of a
washbasin, the ceramic is lowered by maximum of 20 cm.
When the actuating button is pressed and there is no load, the wash-
basin 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.
