Maintenance, cleaning and
decontamination
WARNING!
The precautions described below must be taken
during all the maintenance operations, including
cleaning and replacing of the lter.
■ 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 device, adequate
ltered ventilation of the exhaust air from the
room in which it is disassembled, cleaning of the
maintenance area and suitable personal protection.
Compartments that are not dust-tight must be opened
with suitable tools (screwdrivers, wrenches, etc.) and
thoroughly cleaned.
■ Carry out a technical inspection at least once a
year, for example: check the lters to nd 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 carried out by the manufacturer
or by a competent person.
Primary lter disassembly and replacement
WARNING!
When the vacuum cleaner is used to vacuum
hazardous substances, the lters become
contaminated, therefore:
■ Work with care and avoid spilling the vacuumed
dust and/or material.
■ Place the disassembled and/or replaced lter in a
sealed plastic bag.
■ Close it hermetically.
■ Dispose of the lter in accordance with the laws in
force.
WARNING!
Filter replacement is a serious matter. The lter must
be replaced with one of identical ltering surface
characteristics.
Otherwise the vacuum cleaner will not operate
correctly.
