Service; Filter Replacement - Dustcontrol DC 1800 H EX Notice Originale

Service

6. Clean the maintenance area beforehand.
7. Use suitable personal protective equipment.
8. The fi lter cartridge in the cyclone should be re-
placed as necessary, and at least once a year.
Only use an original fi lter. (Order no. 42028H +
42027H).
9. Motor unit: As part of annual maintenance ,
the fi lters in the motor housing must be repla-
ced (Part No. 432199H). These parts must
be replaced by qualifi ed personnel who have
been trained by Dustcontrol. These fi lters are
part of the explosion protection system. In
the event of high levels of dust, an inspection
should be carried out after 4 months to deter-
mine whether the fi lters should be changed at
more frequent intervals.
10. The machine should be disconnected from
the power supply during cleaning and mainte-
nance. Service operations should never take
place in the zone area.
11. Overload protection. The machine is equip-
ped with overheating protection. If insuffi cient
air fl ows through the motor unit (due to over-
load), the motor will switch off at temperatures
exceeding 55°C (overheating). In these situa-
tions, it is important to determine the cause of
the overheating. Switch off the mains power
and pull out the mains plug, then wait until the
motor has cooled down (up to 30 minutes).

Filter replacement

The fi ne fi lter should be replaced at least once a
year. HEPA fi lters should be replaced after every
300 hours of operation. Wear a dust mask when
replacing the fi lter. Only use an original fi lter.
Release and lift off the lid. To prevent the escape
of dust, place a plastic sack over the cyclone, and
remove the fi lter cartridge. Clean the fi lter plate.
Then fi t the new fi lter.
- CAUTION! Do not reuse the main fi lter once it
has been removed from the machine.

12. As the machines are used in explosive en-
vironments, the functionality of the machine
must be inspected by the manufacturer or
a trained person at least once a year (e.g.
inspection of the fi lter for damage, inspec-
tion of the air tightness of the dust-extraction
machine and function of the control unit, and
inspection of the electrical components, seals
and potential equalisation cables for damage.
Only use original spare parts.
13. To empty the dust collection container, the
two fasteners must be released with care,
one after the other, to prevent dust from being
stirred up unnecessarily. After lowering the
container, (on the DC 2800 H EX) and after
lifting up the top section of the machine (on
the DC 1800 H EX) the extractor should be
switched on again in order for any suspended
particles to be sucked into the fi lter cyclone.
The container can now be completely removed
from the machine. Carefully remove the full
sack from the edge of the bin, and immediately
seal it tight. Fit a new plastic sack, and care-
fully pass the opening back over the edge of
the bin. Make sure that no folds occur, and that
the sack is not damaged. Then carefully install
the bin under the extractor and attach the two
hooks, turn off the machine and secure the bin
to the machine once more, making sure that
the retaining hooks are positioned correctly
(see diagram) and check for leaks.
The HEPA fi lter is removed by opening the lid and
loosening the cartridge. By gently tilting the loos-
ened motor head away from the cyclone, lateral
pressure is exerted on the HEPA fi lter cartridge se-
cured to the motor head. If necessary, repeat this
procedure until the HEPA fi lter cartridge falls into
the fi ne fi lter cartridge. The HEPA fi lter can then be
removed together with the fi ne fi lter, as described
(also see diagram), and disposed of virtually dust-
free. The new fi lter cartridge is placed in the fi ne
fi lter and is sealed by carefully attaching the lid.
