The maintenance service has been active for years on a vast plant park. Maintenance contracts provide for the possibility of choosing an ordinary or complete service. The first provides for the completion of the controls required by law and the checks necessary for the proper functioning of the plant; the second includes, in addition to the provisions of the previous type, the replacement and repair of all parts and materials subject to wear and tear in normal service. It is also possible to stipulate an “all-inclusive” contract in which coverage of the 24-hour assistance service is provided, both on weekdays and holidays, 365 days a year.
