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 Þlters.
WARNING!
The maintenance, cleaning and decontamination
operations must only be performed with the vacuum
cleaner turned off and disconnected from the
pneumatic system.
ŶIf 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 precautions to take include decontamination before
disassembling the vacuum cleaner, Þltered ventilation
of the exhaust air from the room in which the vacuum
cleaner is disassembled, cleaning the maintenance area
and suitable protection for personnel.
ŶA check must be carried out by the manufacturer or the
personnel of the same at least once a year. For example:
check the Þlters to make sure there are no air leaks
from the vacuum cleaner and the pneumatic system is
operating correctly.
Primary and absolute Þlter disassembly
and replacement
WARNING!
When the vacuum cleaner is used to vacuum
hazardous substances, the Þlters become
contaminated, therefore:
Ŷwork with care and avoid spilling the vacuumed
dust and/or material;
Ŷplace the disassembled and/or replaced Þlter in a
sealed plastic bag;
Ŷclose the bag hermetically;
Ŷdispose of the Þlter in accordance with the laws
in force.
WARNING!
Filter replacement is a serious matter. The Þlter must
be replaced with one of identical characteristics,
Þltering surface and category.
Otherwise the vacuum cleaner will not operate
correctly.
