Replacement every two years: why it's important to respect maintenance
The cartridge should be replaced at least once every two years: it is the ideal condition to maintain continuity of treatment and constant performance. Regular maintenance helps protect over time sensitive components of the water and thermal system, reducing the risk of extraordinary interventions and contributing to preserving the overall efficiency of systems that use water (e.g., ACS production, sanitary circuits, and domestic utilities).
Practical installation: quick maintenance and easier management
The replacement of the cartridge is an operation designed to be quick and tidy: by changing only the filtering element, the system's operation is restored without having to intervene on pipes or system components. It is an ideal choice both for the installer who wants to offer a professional and programmable service and for those who desire simpler management of periodic maintenance.
