Afterwards push the drinking water telescopic dome shaft into the extension and adapt it to the planned
area surface.

Inspection and servicing
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
•
Clean surfaces and internal parts with water
•
Remove all dirt from the tank
•
Check that all internal parts are firmly seated.
