Service
During cleaning and service of the unit, the unit
should be disconnected from the power supply.
The fi ne fi lter should be changed at least once per
year. Use only original parts for replacement. If the
unit is equipped with a HEPA fi lter, this fi lter should
be changed every 300 working hours. Use breathing
protection and perform this operation in a contained
area. The used fi lter should be placed in containment
and disposed of in the proper and prescribed method.
Filter change:
Remove the motor head. Lift the fi lter straight up out
of the cyclone. When required, a plastic sack can be
placed over the cyclone for dust-free fi lter change.
The fi lter is lifted directly into the sack.
During the fi lter change, check the fi lter gasket. A
damaged gasket can allow the release of hazardous
dust. Never use old gaskets or after-market fi lters.
Use only genuine Dustcontrol spare parts to maintain
the unit for use on hazardous dusts.
Check regularly that the electrical cable is not dama-
ged. The DC 1800 should be performance tested
at least once per year because it may be used with
hazardous materials. Worn parts must be replaced.
For vacuum motor the typical average life of the
original brushes is 600 - 700 hours. They can then
be exchanged or complete motor/fan replaced.
For 2nd brush set life is ca. 400 hours and for 3rd
brush set ca. 300 hours. After that the commutator
is worn out and the motor needs to be replaced.
