How to replace the Longopac® for machines that
handle dusts that are hazardous to health.
Figure 14
■ Prepare the bag holder with the inside part upwards and
insert the Longopac inside the groove on it. Pull off the
®
Longopac inner end for at least 250 mm, put the strap
®
around the support as shown in the figure, tighten it by
leaving free the excess part of the inner end pulled off
previously. Properly arrange the excess Longopac
the groove (1).
■ Pull off the Longopac
®
close it with the proper band (3).
■ Draw near the bag holder to be placed under the hopper
cone, insert the pins into the slots and turn the system to
lock it at the upper cylinder (4).
■ Pull down the bag closed by the band and lay it on the
tray. Then, by means of the 2nd supplied belt, fasten the
inner end (250 mm-long), which have been previously
removed, above the gasket on the hopper (5).
Main and absolute filter disassembly and
replacement
CAUTION!
When the machine is used to vacuum hazardous
substances, the filters become contaminated, therefore:
■ Work with care and avoid spilling the vacuumed
dust and/or material;
■ place the disassembled and/or replaced filter in a
sealed plastic bag;
■
close the bag hermetically;
■ dispose of the filter in accordance with the laws
in force.
CAUTION!
Filter replacement is a serious matter. The filter must be
replaced with one of identical characteristics, filtering
surface and category.
Otherwise the machine will not operate correctly.
Before proceeding with these operations, turn off the
machine and remove the plug from the power socket.
CAUTION!
Before performing these operations, clean the filter
as described in the "Maintenance, cleaning and
decontamination" paragraph.
CAUTION!
Take care not to raise dust during this operation. Wear
a P3 mask and other protective clothing plus protective
gloves (DPI) suited to the hazardous nature of the dust
collected, refer to the laws in force.
CAUTION!
Reassemble with care to avoid trapping your hands
between the vacuum unit and the container. Use gloves
that provide protection against mechanical risks (EN
388) with a level of protection CAT. II.

Primary filter replacement, for machines equipped
with manual cleaning system
■ Remove the vacuum hose (1).
■ Use the lever (2) to remove the cover (3) together with the
primary filter.
■ Remove the old filter from the cage.
■ Dispose of the old filter according to the laws in force.
■ Fit the new filter and secure it in the cage.
■ Install the cover and the primary filter in the reverse order
of removal.
Primary cartridge filter replacement, for machines
equipped with automatic cleaning system
Before performing any operation on the filter assembly,
shut off the compressed air supply to the tank and vent
off all the air from the tank, through the tap. Stand well
back to prevent air from blasting into the face.

■ Loosen the clamp (2).
■ Remove the vacuum hose (1).
■ Operate the levers (4).
■ Remove the cover (3) and the filter ring (5).
■ Disconnect the power supply cable (7) and the compressed
air supply from the air intake coupling (8).
■ Remove the cartridge assembly (6).
■ Disconnect the connectors (10) and the union (9).
■ Disassemble the air tank by operating on the screws (11).
■ Unlock the fastening devices (12) and lift the cartridges
(13), paying attention to the dust on them and place them
in a plastic bag.
■ Get four cartridges with the same characteristics. These
will be supplied with the gasket which must be positioned
in the relevant housing on the lower side of the cartridge
fastening flange.
Gasket replacement is of the utmost importance since
it must ensure a perfectly tight seal between the filter
chamber and cartridge, thus preventing dust from
leaking out.
