Description; Operation; Service - Dustcontrol DC 5900 Notice Originale

Description

Th e DC 5900 is an electric powered vacuum extractor for use
for source extraction, cleaning and material transportation
applications in most types of industries.
Th e extraction system functions with negative pressure (va-
cuum) that draws the air through suction casings/nozzles,
hose system, separator and fi lter system. Coarse separation
of dust occurs in the unit´s cyclone which is a highly effi cient

Operation

Connect the machine to a suitable power source ac-
cording to the specifi cations found on the identifi cation
label on the machine. If an extension cord is to be used
with the unit, it should be suitably rated according to the
prevailing electrical code and be at least water resistant.
Check rotation of the motor at startup. On machines
equipped with a phase reverser, incorrect rotation can
be easily changed. Machines not equipped with a phase
reverser will require the service of a qualifi ed electrician
to interchange two phases in the power supply.
Th e fi lter should be cleaned 1-2 times per day with conti-
nuous running or if the machine is equipped with a fi lter
monitor, when this is in the red area.
For fi lter cleaning:
1. Start the machine.
2. Close the shutter valve on the machines inlet.

Service

While cleaning and maintenance on the machine, the po-
wer cable should be disconnected from the supply. Check
regularly that the electrical cable is not damaged.
Th e fi ne fi lter should be changed at least once per year.
Use only original spare parts. If the machine is used with
a microfi lter/HEPA fi lter, this should be changed every
300 running hours.Use breathing protection when chang-
ing the fi lter. Care must be taken during the fi lter change
not to expose unprotected persons to harmful dust. Used
fi lters should be sealed in a plastic sack and disposed of
properly.
separator for larger particulate. Th e fi ne dust is separated
and contained by the unit´s fi lter system. Separated material
is collected for disposal in the plastic sack or container at
the base of the cyclone.
Filter cleaning with reverse pulse gives long fi lter life and
constant capacity.
3. Activate the cleaning switch ON and later OFF.
4. Open the shutter valve.
5. If the fi lter condition meter reads green work can con-
tinue. If in the red, pulse clean again. If after several
repetitions, the fi lter condition still shows red the fi ne
fi lter must be changed.
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.
Use only original plastic sacks.

Th e container under the cyclone should be emptied when
it is fi lled to ca 2/3.
When the gauge turns red - close shutter and
open the valve - 4-7 pulses.
Th e DC 5900 should be performance tested at least once
per year because it may be used with hazardous materials.
Worn parts must be replaced.
Never compromise the function of the DC 5900, use only
original spare parts.
Th e turbopump has a very long maintenance free service
life. After approximately 10 000 running hours, the radial
seal between the motor and pump housing should be
greased. Bearings and seals in the motor and turbopump
should be checked and lubricated. Parts worn beyond
serviceable tolerances should be replaced with genuine
spare parts.
