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.
