CAUTION!
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.
■
Fit the tank back in place by repeating the above
operations in reverse order.
Upstream absolute filter replacement
Figure 20
■
Unscrew the knob (1).
■
Remove the cover (2).
■
Release the filter knob (3), cover the filter (4) with a plastic
bag and remove everything.
■
Seal the plastic bag hermetically, insert a new filter unit
which complies with the laws in force and seal the cover
again hermetically.
Downstream absolute filter replacement
Figure 21
■
Unscrew the knob (1).
■
Remove the cover (2).
■
Release the filter knob (3), cover the filter (4) with a plastic
bag and remove everything.
■
Seal the plastic bag hermetically, insert a new filter unit
which complies with the laws in force and seal the cover
again hermetically.
Separator
cleaning
(optional)
Figure 22
[ NOTE ]
If there is only a dust deposit on the separator (4) allow the
dust to drop through the central hole.
The separator (4) should first be disassembled in order to be
perfectly cleaned:
■
Release the closing hooks (1) of the cover (2) and remove
the cover.
■
Remove the filter.
■
Unscrew the two screws (3) and remove it from the
container.
■
Replace the part if it is excessively worn.
■
Reinstall the separator (4).
■
Lock it and fix it by means of the two screws (3).
■
Fit the filter back in place, close the cover (2) and lock it by
means of the two the closing hooks (1).
Tightness inspection
Hoses check
Figure 23
Make sure that connecting hoses (1) are in a good condition
and correctly fixed.
If the hoses are damaged, broken or badly connected to the
unions, they must be replaced.
When sticky materials are treated, check for possible clogging
along the hose, in the inlet and on the baffle plate inside the
filtering chamber.
To clean, scrape the inlet from the outside to remove deposits.

Cover tightness check
Figure 24
If the gasket (1) under the cover (4) has become slack, remove
the screws (2) that lock the closing hooks (3) in place and allow
them to slide downwards until the cover closes perfectly.
Replace the gasket if the degree of tightness is still not optimal.
Filtering chamber gasket check for machines
equipped with dust container
Figure 25
If the gasket (1) between the container and the filtering chamber
(3) fails to guarantee tightness:
■
Loosen the four screws (2) that lock the filtering chamber
(3) against the machine structure.
■
Allow the filtering chamber (3) to lower down and tighten
the screws (2) once it has reached the tightness position.
If an optimal seal is not yet obtained or if there are tears, cracks,
etc., the gasket must be replaced.
Filtering chamber gasket check for machines
equipped with Longopac
Figure 26
Ensure that the Longopac® bag is tight with the gasket (2).
Also check the seal of the gasket positioned on the discharge
clapet (1).
The gasket must be replaced if it is torn, cut, etc...
Disposal
Figure 27
The crossed-out wheeled bin symbol on the equipment indicates
that used electrical and electronic equipment must be collected
and disposed of separately from household waste. The correct
disposal of the equipment will help prevent potential negative
consequences for the environment and human health.
Electrical and electronic household equipment must be
disposed of at the separate collection points in the residence
area. Please note that commercial electrical and electronic
equipment should be disposed of separately from the municipal
waste stream. We will be pleased to inform you about suitable
disposal options.
