NOTE B
A special device (optional) on the equipment signals the need to replace the filters. It is however recom-
mended to check whether the filters are clogged for maximum suction and machine efficiency; for this
reason the cleaning interval described in the filter paragraph should be respected and the entire filter set
should be replaced at least once a year. The filters deteriorate even if they are not used very often.
NOTE C
The fan extractor must be monitored at intervals established by the user to check that it is good working
order, to check for faults or damage to the impeller and to check that the electric motor is in good condition.
NOTE D
This is the lifecycle defined for the bearings, however due to external factors such as increased vibrations for
a certain period of time the replacement of the bearings may have to be carried out at shorter intervals. At
the end of their lifecycle, the bearings should be replaced even if apparently they seem in good condition.
