NOTE A
The cleaning intervals vary according to the type of fluid conveyed and its concentration and also according to the
type of work environment in which it is used. The end user must therefore define a cleaning interval suitable to
always keep the machine perfectly clean; the accumulation of material on the fixed parts must not be more than 5
mm thick.
NOTE B
A special device fitted on all equipment signals the need to replace the filters. It is however recommended 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.
