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.

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 (mate-
rial 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.

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 interme-
diate section).
Attention: It is essential to use the cast telescopic dome shaft (with class B cast cover).
