Extraordinary maintenance
Turn off the unit before routine maintenance and wait at least 120 seconds before per-
forming maintenance.
One can not predict extraordinary maintenance as it is normally due to effects of wear or fatigue caused
by the incorrect operation of the unit.
REPLACEMENT OF PARTS
The replacement of parts should be performed by expert personnel::
• Qualified maintenance mechanic
• Qualified maintenance electrician
• Manufacturer technician
The unit is designed to be able to perform all the servicing necessary to maintain good efficiency of the
components. However, it sometimes happens that a component fails due to malfunction or wear, so for
replacement refer to the executive drawing.
These are the components that may need replacement:

For some of these operations of a general nature we will not enter into detail as these are operations that
fall within the abilities and professional expertise of the staff assigned to perform them.
CONSUMABLE COMPONENTS - SPARE PARTS
During the operation of the unit there are particular mechanical and electrical components that are most
subject to wear. These parts must be monitored in order to carry out their replacement or repair before
they cause problems to the correct operation of the unit with consequent downtime.
