4.2 MAINTENANCE CALENDAR
Due to its design, the MIR 9000 requires simplified maintenance only.
However, to guarantee its described characteristics for continuous operation, maintenance should be
carried out frequently on the analyzer.
During the period after its initial start-up and before its actual use, it is necessary to monitor the
evolution of the installation judiciously by paying a daily visit. After this short period of 5 days, a weekly
inspection visit will be sufficient. During this visit it will be possible to make up the maintenance
calendar for the user site in a precise way.
The interval between two visits is usually 1 month.
