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!
The entire system must be checked for leaks, cleanliness and stability at least every three months.
The entire system should be serviced at intervals of approx. 5 years. In this case, all parts of the system
must be cleaned and their function checked. Servicing should be carried out as follows:

Drain the tank completely

Remove solid residue with a soft brush

Clean surfaces and internal parts with water

Remove all dirt from the tank

Check that all internal parts are firmly seated.
