PREVENTIVE MAINTENANCE
The required maintenance intervals depend largely on the quality of the incoming water
and how often the machine is used. The maintenance interval will have to be determined
in each individual case. We recommend that the stated maintenance operations are done
once or twice a year.
Periodic maintenance
This must only be done by authorized personnel.
The machine is connected to the electricity supply and some components are
live.
