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)
installed.

6.2

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 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.

Telescopic dome shaft on which persons may walk

Important: To prevent loads from being transferred onto the

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!
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
supported with concrete
layer 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. 1800 mm
possible with intermediate section).
Attention: Use the cast cover under all circumstances.
