Maintenance and care
Danger
First pull out the plug from the mains before
carrying out any tasks on the machine.
Dust extracting machines are safeguards
for the prevention or elimination of hazards
defined in the regulations of BGV A1.
In order to carry out maintenance work,
–
the user must disassemble, clean and
service the unit, in so far as this is pos-
sible without endangering maintenance
personnel and other persons. Suitable
precautions include decontamination
before the unit is disassembled. Pre-
cautions must be taken for local filtered
forced air ventilation at the place where
the unit is disassembled, the cleaning of
the maintenance surface and suitable
protection of the personnel.
The outside of the unit should be
–
cleaned thoroughly and any harmful
substances removed. Alternatively, a
sealed coating may be applied before
the unit is removed from the danger ar-
ea. All unit parts are to be considered
contaminated when they are removed
from the danger area. To avoid distribu-
tion of the dust, you must take the ap-
propriate measures.
In the framework of maintenance and
–
repair work all contaminated objects
that cannot be cleaned satisfactorily
must be disposed of. Such objects must
be disposed of in impermeable bags in
accordance with the valid provisions for
the disposal of such waste.
When transporting or maintaining the
–
appliance, the suction openings must
be closed with the connection bushings.
Warning
Safety equipment for preventing hazards
must be serviced and maintained regularly.
This means that the manufacturer's staff or
persons trained by the manufacturer must
check the equipment for proper functioning
at least once a year, i.e. check for leaks, fil-
26
ter damage, functioning of the controlling
elements, etc.
Danger
You can test the filtration capacity of the de-
vice using the test procedure specified in
EN 60 335–2–69 AA.22.201.2. This test
must be done at least once a year or more
frequently if the national regulations de-
mand it. If the test results are negative, the
test is to be repeated with a new flat-fold fil-
ter.
Note: Vacuum cleaners of dust class H
must be maintained as needed, but at least
once per year, repaired as necessary and
checked by a skilled expert (qualified as per
TRGS 519 Nr. 5.4.3, paragraph 2). The test
result must be presented upon request.
Caution
Risk of damage! Do not use detergents
containing silicone to clean.
No outside help is required for carrying
–
out basic maintenance and cleaning.
The appliance surface and the inside of
–
the container should be cleaned regu-
larly using a damp cloth.
Danger
Risk due to dust hazardous to health. Al-
ways use disposal clothing and P2 or high-
er breath-safe masks while carrying out
maintenance tasks (such as changing fil-
ters).
Exchanging the flat pleated filter
Danger
The dust that has been collected should be
transported in dust-proof containers. No re-
filling is permitted. The waste containing
asbestos is to be disposed off according to
the rules and regulations for waste dispos-
al.
Warning
Do not reuse the main filter element after it
has been removed from the appliance.
Non-detachable filters should only be re-
placed in suitable rooms (so-called decon-
tamination stations) by an expert.
