8 MAINTENANCE
8.1 General
Maintenance must be done by authorized centres or by
qualified personnel
The maintenance allows to:

maintain the unit efficiency

reduce the deterioration speed to whom every
equipment is subject over time

assemble information and data to understand the
state of the unit efficiency and avoid possible
damages
Before checking, please verify the following:

the electrical power supply line should be isolated
at the beginning

the unit isolator is open, locked and equipped with
the suitable warning

make sure no tension is present
After turning off the power, wait at least 5 minutes
before accessing to the electrical panel or any other
electrical component.
Before accessing check with a multimeter that there
are no residual stresses.
8.2 Inspections frequenty
Perform an inspection every 6 months minimum.
The frequency, however, depends on the use.
In the event of frequent use it is recommended to plan
inspections at shorter intervals:

frequent use (continuous or very intermittent use,
near the operating limits, etc)

critical use (service necessary)
