Maintenance and cleanness
Routine maintenance and cleanness can be exclusively done when the
equipment is not connected to the mains. Disregarding this caution, may
have the effect of serious problems to the personal safety.
For no reasons, the equipment should have any contacts with water or
other liquids.
To clean the equipment, only use a soft cloth. In case that much dust is
accumulated inside the equipment, use a vacuum-cleaner or a dry and
soft brush to remove it.
The routine maintenance of the equipment is intended also as the
periodical control of the operational parameters, following the instructions
written in the chapter “putting in operation”.
