Donaldson Company, Inc.
Instruct all personnel on safe use and maintenance
procedures.
Use proper equipment and adopt
all safety precautions needed for
servicing equipment.
Use appropriate access equipment and
procedures. Note the standard collector is not
equipped with access platforms unless noted
on the specification drawings.
Electrical service or maintenance work must
be performed by a qualified electrician and
comply with all applicable national and local
codes.
Turn power off and lock out electrical
power sources before performing service or
maintenance work.
Do not install in classified hazardous
atmospheres without an enclosure rated for
the application.
Operational Checklist
1. Monitor the physical condition of the collector and
repair or replace any damaged components.
Routine inspections will minimize downtime and
maintain optimum system performance. This
is particularly important on continuous-duty
applications.
2. Monitor exhaust.
Disposable Filter Liner Replacement
Turn unit OFF and check that drum
has stopped before removing the
cover.
1. Using a felt tip marker or scribe, mark the location of
the liner ends on the face of the drum.
2. Remove and discard disposable liner.
3. Starting at the mark made in Step 1, slide the
replacement liner under each blade until the ends
come together.
Do not trim the filter if it seems too
long. Work the excess filter liner
around the drum evenly.
4. Replace the cover and clamping ring, turn power ON
and allow unit to reach full speed.
5. Turn unit OFF and allow drum to stop. Remove the
inlet cover and inspect liner. It should be smoothly
seated and the butt joint flat. If liner overlaps at the
seam or wrinkles are present, smooth troublesome
areas by hand and repeat Steps 4 and 5.
If unit runs rough after filter liner
replacement, shift the liner seam
a few inches to the right or left of the reference
mark.
Primary Filter Replacement
Under normal operating conditions and scheduled filter
liner replacement, the primary filter will not require
replacement. It is strongly recommended that this filter is
not removed. The dynamic balance of the drum assembly
will be affected.
Delayed maintenance or accidental damage can make
replacement necessary. Follow the same procedure used
for replacing the disposable filter. Trial and error shifting
of the seam will be necessary to minimize vibration. If the
drum is distorted, it may be necessary to re-balance the
unit.
Secondary Filter Replacement
The third stage secondary-filter replacement requires
the removal of the rotating drum.
