Assembling the and telescopic dome shaft
6.1
Assembling the telescopic dome shaft
The telescopic dome shaft enables infinite adaptation of the tank
to given site surfaces with earth coverage of between 455mm
and 655mm (standard telescopic dome shaft) or 455mm and
755mm (trafficable 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 the soft soap supplied (do not use
mineral oil-based lubricants, as these attacks the seal). The
telescope is then also lubricated, inserted and aligned with the
surface of the site.
6.2
Telescopic dome shaft on which persons may walk
Important:
To prevent loads from being transferred onto the
tank,
(7mm Minus) is filled 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 and tightened to prevent entry by
children.
6.3
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 grey) 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 permitted coverage
above the shoulder of the tank is min.
700 mm
and max.
1000mm
.
Attention:
Use the cast cover under all circumstances.
