When it is necessary to vacuum very fine dust continuously
without stopping to clean the filters, the Manufacturer provides
the machine of a multi-cartridge filtering system.
The unit is equipped with a fully automatic electropneumatic
device to alternately clean the filtering cartridges, which
guarantees continuous service.
Electric panel, powered with a 24V rating, is complete with
cyclic timer to regulate the following times:
T1
Filter cleaning time
Opening time of the solenoid valve for backwashed air exhaust
into the cartridge.
The shorter the time, the more energetic the cleaning action
will be.
T2 Work hold time
Time between one cartridge cleaning operation and the next.
T3
Time between cleaning cycles
Time between one cleaning cycle and the next.
Check the arrows on the knobs of the timer for the exact
regulation.
Replace the filter element if the vacuum gauge pointer stays
in the red zone even after the filter has been shaken (see
"Primary and absolute filters disassembly and replacement").
If the indicator is still in the red area. The vacuum hose or
one of the accessories may be clogged, and not the filter.
Clean these parts if this is the case.

The filtering cartridges (2) serve the purpose of filtering the
intake air. The vacuum cleaner is equipped with solenoid valves
(1 ) that, by deflecting the air coming out of the blower, allow for
cyclic cleaning of the filtering cartridges (2). The fully automatic
system grants work continuity and is driven by a cyclic timer (3 )
that allows to adjust the intervals T0, T1, T2 which define the
cleaning cycle.

The factory setting of the cycle intervals is the one
that allows for a better cleaning in the majority of
applications, for this reason the factory setting should
not be modified. If necessary, for heavy applications
(for example, to collect heavy quantities of very thin
dust - more than 3 kg per minutes), it is possible to
modify the intervals by following the instructions in the
Service Manual, available at the Manufacturer's Service
Centre.
Replace the filter element if the vacuum gauge pointer stays
in the red zone even after the filter has been shaken (see
"Primary and absolute filters disassembly and replacement").
If the indicator is still in the red area. The vacuum hose or
one of the accessories may be clogged, and not the filter.
Clean these parts if this is the case.
