Maintenance, cleaning and decontamination

DANGER !
IMPORTANT: The precautions described below must be
taken during all the maintenance operations, including
cleaning and replacing of the main and HEPA filters.
A. To allow the user to carry out the maintenance
operations, the vacuum cleaner must be
disassembled, cleaned and overhauled as far as
is reasonably possible, without causing hazards
for the maintenance staff 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 of the maintenance area and
suitable personal protection.
B. If the vacuum cleaner belongs to the M or H class, the
external parts 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
conforming to the applicable regulations and in
accordance with the local laws governing the disposal
of such material.
This procedure must also be followed when the filters
are eliminated (main, HEPA and downstream filters).
IMPORTANT: Compartments that are not dust-tight must be
opened with suitable tools (screwdrivers, wrenches, etc.)
and thoroughly cleaned.
C. Carry out a technical inspection at least once a year,
for example: check the 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. This inspection must be
I
carried out by the manufacturer or by a competent
person.

Primary and absolute filter disassembly and
replacement
DANGER !
When the vacuum cleaner is used to vacuum 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 laws in
force.
DANGER !
Filter replacement is a serious matter. The filter must be
replaced with one of identical characteristics, filtering
surface and category.
Otherwise the vacuum cleaner will not operate correctly.

Primary filter replacement

DANGER !
Check the vacuum cleaner class (M - H).
Take care not to raise 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 the laws in force.
Before proceeding with these operations, turn off the vacuum
cleaner and remove the plug from the power socket.
