Introduction
The correct maintenance of the unit and connected devices ensures proper operation over time.
Maintenance operations must be carried out by expert personnel (see "Recipients” on page 4) in
accordance with safety regulations (see “Safety requirements” on page 5) and the maintenance

If there are anomalies or malfunctions it is necessary to identify the cause and eliminate it before
continuing use of the unit.

electricians (IEV 195-04-01: person with relevant education and experience to

a part or all of the installation.
