Maintenance, cleaning and
decontamination
Use only genuine spare parts supplied and authorized
by the manufacturer.
The precautions described below must be taken
during all the maintenance operations, including
cleaning and replacing of the main and HEPA filters.
■ 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 vacuum
cleaner, adequate filtered ventilation of the exhaust air
from the room in which it is disassembled, cleaning of 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
conforming to the applicable regulations and in
accordance with the local laws governing the disposal of
such material.
This procedure must also be followed when the filters are
eliminated (main, HEPA, downstream filters).
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 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. This inspection must be carried out by
the manufacturer or by a competent person.
