Maintenance, cleaning and
decontamination
WARNING!
To guarantee the safety level of the vacuum cleaner,
only original spare parts supplied by the manufacturer
should be used.
WARNING!
The precautions described below must be taken
during all maintenance operations, including cleaning
and replacing the primary and absolute filters.
WARNING!
The maintenance, cleaning and decontamination
operations must only be performed with the vacuum
cleaner turned off and the plug disconnected from
the power socket.
It is absolutely forbidden to perform maintenance
with the plug connected to the socket.
Danger of electric shock!
■ If the user is performing the maintenance operations,
the vacuum cleaner must be disassembled, cleaned
and overhauled as far as reasonably possible without
hazards for the maintenance personnel or other people.
The suitable precautions include decontamination before
disassembling the vacuum cleaner, adequate filtered
ventilation of the exhaust air from the room in which it
is disassembled, cleaning the maintenance area and
suitable personal protection.
■ The external parts of the vacuum cleaner must be
decontaminated by cleaning and vacuuming methods,
dedusted or treated with sealant before being taken out
of a hazardous zone.
■ All parts of the vacuum cleaner must be considered
as contaminated when they are removed from the
hazardous zone and appropriate actions must be taken
to prevent dust from dispersing.
■ When maintenance or repair procedure are carried out,
all the contaminated elements that cannot be properly
cleaned, must be eliminated.
■ These elements must be disposed of in sealed bags in
accordance with applicable regulations and local laws on
the disposal of such material.
■ This procedure must also be followed when the filters are
eliminated (primary and absolute filters).
■ Compartments that are not dust-tight must be opened
with suitable tools (screwdrivers, wrenches, etc.) and
thoroughly cleaned.
■ A check must be carried out by the manufacturer or
qualified personnel at least once a year. For example:
Check the air filters to find out whether the air-tightness
of the vacuum cleaner has been impaired in any way
and make sure that the electric control panel operates
correctly.

Main and absolute filter disassembly and
replacement
When the vacuum cleaner 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.
Filter replacement is a serious matter. The filter must
be replaced with one of identical characteristics, filter-
ing surface and category.
Otherwise the vacuum cleaner will not operate cor-
rectly.
Before proceeding with these operations, turn the
vacuum cleaner off and disconnect the plug from the
power socket.
How to replace the primary filter
Before proceeding with these operations, turn off the vacuum
cleaner and remove the plug from the power socket.
■ Turn off the vacuum cleaner by placing the two switches
in the "OFF" position.
■ Shake the primary filter by turning the lever (5) clockwise/
counterclockwise for at least 5 complete cycles.
■ Release the closing band (7).
■ Remove the head (8) and the cage. but do not lift the star
filter (9).
■ Remove and dispose of the filter according to the laws in
force.
■ Reset the vacuum cleaner by fastening the new filter on
the ring (10) with the metal clamp
■ Install the head and the cage in the primary filter by
taking care that there is one spoke of the cage every two
pockets of the star filter.
■ Check the correct position of the shaker handle (12).
■ Fasten the closing band.
Take care not to raise dust when this operation
is carried out. Wear an N100 (P3) mask and other
protective clothing plus protective gloves (PPE/DPI)
suited to the hazardous nature of the dust collected;
refer to the laws in force.
Reassemble with care to avoid trapping your hands
between the vacuum unit and the container. Use
gloves that provide ANSI/ISEA Level "2" protection.
