Maintenance, cleaning and
decontamination
WARNING!
To guarantee the safety level of the device, only
original spare parts supplied by the manufacturer
should be used.
WARNING!
The precautions described below must be taken
during all the maintenance operations, including
cleaning and replacing of the main and HEPA lters.
■ To allow the user to carry out the maintenance
operations, the device 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.
■ 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 in
accordance with applicable regulations and local laws on
the disposal of such material.
This procedure must also be followed when the lters are
eliminated (main, HEPA and downstream lters).
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 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.
WARNING!
In particular, on Class H vacuum cleaners, the ltering
efciency 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 ltering
efciency of the vacuum cleaner is indicated in
standard EN 60335-2-69, par. AA.22.201.2.
If the test isn’t passed, it must be repeated after the
class H lter has been changed.
