4.0 Service
4.1 Dust Removal
Do not let the dustbin overfill. It can cause
poor dust collector performance.
Turn off the dust collector and empty the
dustbin on a regular base (recommend to
empty the dustbin when 1/2 full).
For the spark trap: do not forget to empty it.
Use a vacuum cleaner through the access
cover on the spark trap.
4.2 Replacing of Filter Elements
Caution
：
When the airflow is low or the differential
pressure is too high and alarm, must change
the filter elements. After operating more than
2000—4000 hours continuously, must
change the filter elements.
All filter elements should be changed at the
same time.
Do not drop the new filter element on the
floor or any other hard surface. It is
necessary to clean the dust of the tube sheet
all around the opening to ensure a positive
seal of the gasket.
Slide the new filter element along the yoke
with the gasket end facing inward towards
the clean air chamber.
Reinstall the cover and screw the wing nut
clockwise onto the yoke. Tighten securely, to
prevent leakage.
Caution
Disconnect electrical power before
servicing.
Shut off and bleed compressed air
supply before servicing any compressed
air components.
The filter elements are cleaned
automatically and sequentially. Don’t
move out the filter elements and clean.
