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 the
personnel of the same 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.
In particular, on Class H vacuum cleaners, the filtering
efficiency of the vacuum cleaner must be checked at
least once a year, or more often if required by national
legislation. The test method for checking the filtering
efficiency of the vacuum cleaner is indicated in
standard EN 60335-2-69, par. 22.AA.201.2.
If the test isn't passed, it must be repeated after the
class H filter has been changed.
This Class H vacuum cleaner can collect dust
hazardous for the health. The procedures for servicing
and emptying the vacuum cleaner including removing
the dust bag, must only be performed by specialised
personnel wearing protective clothing. Do not use
without the complete filter system in place.
