2.2.2 Operating mode
The height-adjustable washbasin element is operated without electronics and functions with the help of a gas pressure spring.
The gas pressure spring enables continuous adjustment of the seat
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 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 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.
2.2.3 Compatible components
The element is suitable for washbasin ceramics with a fixing interval of
280 mm. The maximum washbasin width is 700 mm.
The cover plate 8064.22 is required for the detailed installation.
2.2.4 Sound protection
The washbasin element fulfils the requirements in acc. with DIN 4109 as
well as the increased requirements in acc. with
DIN 4109 (supplementary sheet 2) and the requirements in acc. with
VDI 4100 SSt I-SSt III.

3.3 Lifting and lowering the washbasin
The washbasin can be lifted and lowered hydraulically within a 20 cm
range with the help of a built-in gas spring.
The maximum hydraulically adjustable weight of the washbasin
including the fitting, among other things, is from 15 up to 21 kg.
If necessary, help a little by hand (push up or lean on it),
until the full adjusting distance is achieved.
The washbasin is secured and released (adjustability on/off) with the
actuation button.
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.
