How to disassemble and replace the main and
Hepa filters
ATTENTION DANGER!
When the vacuum cleaner is used to clean up hazardous
substances, the filters become contaminated, thus:
–
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 current
laws.
ATTENTION DANGER!
Filter replacement is a serious matter.
The filter must be replaced with one of identical
characteristics, filter surface and category.
Failing this, the vacuum cleaner will not operate correctly.

ATTENTION DANGER!
Take care not to raise the dust when this operation is
carried out. Wear a P3 mask and other protective clothing
plus protective gloves (DPI) suited to the hazardous nature
of the dust collected. Refer to laws in force.
Replacing the upstream Hepa filter
–
Unscrew knob "A" (Fig. 13);

Remove cover "B" (Fig. 13);
–
Release knob filter "C" (Fig. 13), cover the filter "D" with a
plastic bag and remove everything;

Note
If the vacuum cleaner is type B1 for zone 11 (version 1 - BIA):
conduct galvanic continuity tests in accordance with the
accident prevention standards (e.g. VBG4 and according to DIN
VDE 0701 part 1 and part 3).
Standard EN 60335-2-69 prescribes inspections at regular
intervals or after all repairs or modifications).
Inspecting and cleaning the motor cooling fan
Periodically clean the motor cooling fan to prevent the electric
motor from overheating, particularly if the appliance is used in a
dusty place.
Seal inspection
Checking the condition of the hoses
Make sure that connecting hose hoses "A", "B" and "C" (Fig. 14)
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 hose "C" (Fig. 14), in outlet and on the baffle in the
filtering chamber.
Scrape outside the outlet and remove the deposited waste as
indicated in figure 14.
Checking the lid seal
If seal "A" (Fig. 15) under lid "D" has become slack, unscrew
screws "B" that lock fastening latches "C" in place and allow
them to slide downwards until lid "D" closes perfectly.
Now tighten locking screws "B" (Fig. 15).
Replace seal "A" (Fig. 15) if an optimum seal cannot be
obtained.
Checking the tightness of filter chamber
If seal "A" (Fig. 16) between the container and filter chamber "C"
fails to guarantee tightness:
–
loosen the four screws "B" (Fig. 16) that lock filter chamber
"C" against vacuum structure.
–
Allow filter chamber "C" (Fig. 16) to lower down and relock
screws "B" once it has reached the retention position.
The seal must be replaced if it is torn, cut, etc.
Replace seal "A" (Fig. 16) if the degree of tightness is still not
optimum.
