8. PERIODIC MAINTENANCE

Please note that the periodic maintenance of the air valve is an integral part of the proper pipeline maintenance
regime; it should be maintained at least once a year in accordance with the quality and composition of the fluid in the
system.

Important:

Before performing any work on the air valve make sure that all workers on site are familiar with the safety

instructions as appear in Chapter 1 of this document and with all the relevant local and general safety instructions,
standards and work regulations.

Please note

that maintaining the D-025 ARISENSE product consists of two separated procedures: Maintaining the Air

Valve Component and maintaining the Arisense component.
