Dustcontrol 94114-D Notice Originale page 13

Service
During cleaning and service of the unit, the unit should be
disconnected from the power supply.
Th e 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. Th e 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. Th e fi lter is lifted
directly into the sack.
During the fi lter change, check the fi lter gasket. A dama-
ged 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.
Th e 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. Th ey 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.
