Maintenance, cleaning and
decontamination
WARNING!
The precautions described below must be taken
during all the maintenance operations, including
cleaning and replacing of the filter.
■ 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
filtered 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, e.g.: check the air filter 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 carried out by the manufacturer or by a
competent person.
Filter disassembly and replacement
WARNING!
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 filters
in a sealed plastic bag.
■ Close it hermetically.
■ Dispose of the filters in accordance with the
laws in force.
WARNING!
Filter replacement is a serious matter. The filters
must be replaced with ones of identical filtering
surface characteristics.
Otherwise the vacuum cleaner will not operate
correctly.
