Description
The DC 5900 is an electric powered vacuum extractor for
use for source extraction, cleaning and material transpor-
tation applications in most types of industries.
The extraction system functions with negative pressure
(vacuum) 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 separator for larger particulate. The fi ne
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.
The fi lter should be cleaned 1-2 times per day with con-
tinuous 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.
3.
Activate the cleaning switch ON and later OFF, 4-7
pulses.
Service
While cleaning and maintenance on the machine, the
power cable should be disconnected from the supply.
Check regularly that the electrical cable is not damaged.
The 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
changing 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.
The DC 5900 should be performance tested at least
2018-03-08
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.
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. If it remains on red, despite
changing the fi lter, the vaccum relief valve needs to
be checked.
The plastic sack should be changed only after the fi lter
has been cleaned. The sack should be changed when the
dust level is about 5 cm under the foot valve. The plastic
sack should be sealed after removal from the machine.
Use only original plastic sacks.

The 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.
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.
The 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.
