Assembling the tank dome and telescopic dome shaft
6.1
Assembling the tank dome
Prior to assembly, the enclosed seal is locked
onto the tank neck's profile „B". The tank dome is
then aligned with the piping connections and is
locked to the tank neck. It is essential to make
sure that the upper seal "A" (pre-assembled) is
correctly installed.

Assembling the telescopic dome shaft
The telescopic dome shaft enables infinite adaptation of the tank to
given site surfaces with earth coverage of between 750 mm and
950 mm (Mini telescopic dome shaft) or 750 mm and 1050 mm (Maxi
telescopic dome shaft).
For assembly purposes, the enclosed profile seal (material EPDM) is
inserted into the tank dome's sealing groove and is coated generous-
ly 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.
6.3
Telescopic dome shaft on which persons may walk
Important: To prevent loads from being transferred onto the
tank, round-grain gravel
layers around the telescope
age to the tank dome
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!
6.4
Telescopic dome shaft over which passenger cars
may drive
If the tank is installed under areas used by passenger cars, the
collar area of the telescope
ported with concrete
of concrete to be installed must be at least 400 mm wide and
approx. 200 mm high all around. The minimum coverage above
the shoulder of the tank is at least 800 mm (max. 1050 mm with
telescope, coverage up to max. 1500 mm possible with interme-
diate section).
Attention: It is essential to use the cast telescopic dome shaft (with class B cast cover).
