6. Assembling the tank dome and telescopic dome shaft
6.1
Assembling the tank dome
Prior to actual assembly, the enclosed seal is inserted into the tank domes’s realing groove (A), the
tank dome is then aligned with the pipes and is locked to
the tank. Once engaged, it can no longer be rotated.It
must be absolutely paid attention to the seat of the upper
seal.
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
tank, round-grain gravel
(max. grain size 8/16) is filled in in
layers around the telescope
and is evenly compacted.
Damage to the 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!
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
(colour anthracite) must be
supported with concrete
(load class B25 = 250 kg/m²). The
layer of concrete to be installed must be at least 300 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. 1200 mm possible
with intermediate section).
Attention: Use the cast cover under all circumstances.
