Service
During cleaning and service of the unit, the unit should be
disconnected from the power supply.
The fine filter should be changed at least once per year. Use
only original parts for replacement. If the unit is equipped
with a HEPA filter, this filter should be changed every 300
working hours. Use breathing protection and perform this
operation in a contained area. The used filter should be
placed in containment and disposed of in the proper and
prescribed method.
Filter change:
Remove the motor head. Lift the filter straight up out of the
cyclone. When required, a plastic sack can be placed over
the cyclone for dust-free filter change. The filter is lifted
directly into the sack.
During the filter change, check the filter gasket. A dama-
ged gasket can allow the release of hazardous dust. Never
use old gaskets or after-market filters. 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 ori-
ginal 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.
