shaft
The telescopic dome shaft enables infinite adaptation of
the tank to given site surfaces with earth coverage of
between 750 mm and 1050 mm.
For assembly purposes, the enclosed profile seal (material
EPDM) is inserted into the tank dome's sealing groove and
is coated generously with soft soap (do not use mineral oil-
based lubricants, as these attack the seal). The telescope
is then greased, inserted and aligned with the surface of
the site.

Important: To prevent loads from being transferred onto the tank,
round-grain gravel (max. grain size 8/16) is filled in layers

tank dome and telescope must be avoided during this step. The
cover is then positioned and is sealed to prevent entry by children.
Tighten the threaded connection on the cover so tightly that it
cannot be opened by a child! For a professional installation of a
drinking water cover, the telescopic dome shaft must reach about
20 cm above the ground level.
