Description
Th e DC 3800c Twin is stable, tough and reliable and
particularly suited to source extraction where high
densities of dust are created. DC 3800c Twin is suitable
in many diff erent applications e.g. concrete grinding or
other applications where large quantities of dust need to
be extracted.
Th e DC 3800c Twin is driven by two single-phase mo-
tors.
Note! Th e machine is equipped with soft start to mini-
mise the start current (6 second start period).
Th e extraction system works as a vacuum that pulls the
air through suction casings/nozzles, the hose system,
Operation
Connect the machine to a suitable power source ac-
cording to the specifi cation plate on the machine. If the
electrical cable on the machine is damaged it should be
replaced.
Th e DC 3800c Twin is equipped with a fi lter indication
lamp that indicates when the fi lter needs cleaning or
changing. Th e fi lter is generally cleaned once or twice
daily during normal continuous operation.
Reverse pulse fi lter cleaning:
Alternative 1 (e.g. concrete grinding machine with fi xed
connection)
1.
Start the machine. Note! 6 second start period.
2.
Close the shutter valve.
3.
Open the fi lter cleaning port with a quick mo
tion. Repeat three to six times. Th is reverse
pulse of air cleans the fi lter.
4.
Open the shutter valve.
5.
If not the fi lterindication lamp does not go out,
change fi lter.
Alternative 2 (e.g. suction hose connected for cleaning)
separator and fi lter section. Coarse separation of dust oc-
curs in the unit's pre-separator, which is a highly effi cient
separator for larger particulate. Th e fi ne dust is separated
and contained by the fi lter system. Reverse pulse fi lter
cleaning gives long fi lter life and a consistently high
suction capacity without having to remove the fi lter. Th e
machine is equipped with a secondary HEPA fi lter.
Extracted material is collected in 40 l plastic sacks. A dust
free sack change can be done very easily by hand.
Th e collected material is then easy to handle for disposal
or recycling. Th is is the case for the pre-separator cyclone
sack and the fi lter cyclone sack.
1.
Start the machine.
2.
Disconnect the hose from the suction casing.
Put the free end of the suction hose over the
left handle. Push it towards the stop plate.
3.
Open the fi lter cleaning port with a quick
motion. Repeat three to six times. Th is reverse
pulse of air cleans the fi lter.
4.
Reconnect the hose to the suction casing.
5.
If not the fi lterindication lamp does not go out,
change fi lter.
Th e plastic sack should be changed only after the fi lter
has been cleaned. Th e sack should be changed when the
dust level is about 5 cm under the foot valve. Th e plastic
sack should be sealed after removal from the machine.
Only use original Dustcontrol plastic sacks.
