Assembling the tank dome

Prior assembly, the enclosed seal
is locked onto the tank neck's
profile „B". The tank dome is then
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
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.
