Assembling - Telescopic Dome Shaft; Drinking Water Telescopic Dome Shaft; Drinking Water Lid - Graf Diamant Notice D'installation Et D'entretien

The telescopic dome shaft allows the tank to be adapted in a continuously variable manner to terrain
surfaces with between 700 mm and 1000 mm of soil cover (the telescope can be shortened by 250 mm
from below if necessary).
To assemble, the profile seal (closed circuit) (material EPDM) provided is inserted in the tank's sealing
groove and rubbed in with plenty of soft soap (do not used lubricants with a mineral oil base because they
will corrode the seal). The telescope is then greased, slid in and aligned to the terrain surface.

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! For a professional installation of a
drinking water cover, the telescopic dome shaft must reach
about 20 cm above the ground level.
5.2

Drinking water lid

The drinking water telescope is provided with a
second lid that rests on top. This is also always placed
on the rim of the telescope to prevent any dirt entering
the tank, except when working in the tank.
The seal must be in place in the groove around the
entire circumference before the lower telescope lid is
positioned.
ATTENTION: The upper drinking water lid serves only
as a protective cover and is not safe to walk on!
