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, 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!

If an intermediate piece is needed for larger earth covers it is
inserted into the tank dome with the aid of soft soap. The profile
seal is fitted in the topmost groove of the intermediate piece
and greased with plenty of lubricant. Then slide the mains water
telescopic dome shaft into place and adjust to suit the planned
terrain surface.
