Check Monthly
1. Proper solenoid and diaphragm valve operation.
2. If equipped, check door seals for condition and
contact. Replace or adjust as necessary.
3. If equipped, check that the clean-air plenum is free
of dust accumulation. If dust is present, check the
surrounding filter bags for tears or loose seals.
Check Annually
Moisture Separator
Isolate the compressed-air supply and remove and clean
the filter.
Compressed-Air Manifold
Isolate the compressed air supply, remove the drain plug
and air inlet connections and clean thoroughly.
Filter Bags
Remove one or two filter bags and inspect for general
condition. Replace if necessary.
Jet Tubes
Check that jet tubes are clean and the orifices are clear.
Maintenance Information
Instruct all personnel on safe use and maintenance
procedures.
Use proper equipment and adopt
all safety precautions needed for
servicing equipment.
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.
Turn compressed air supply OFF and bleed
lines before performing service or maintenance
work.
Do not set compressed-air
pressure above 100-psig.
Component damage can occur.
All compressed air components must be sized
to meet the maximum system requirements of
90-100 psig supply pressure.
The compressed-air supply must be oil
and moisture free. Contamination in the
compressed air used to clean filters will result
in poor cleaning, cleaning valve failure, or poor
collector performance.
Purge compressed air lines to remove debris
before connecting to the unit’s compressed air
manifold.
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. Periodically check the compressed air components
and replace compressed air filters.
Drain moisture following the manufacturer’s
instructions. With the compressed air supply ON,
check the cleaning valves, solenoid valves, and
tubing for leaks. Replace as necessary.
3. Monitor pressure drop across filters.
Abnormal changes in pressure drop may indicate a
change in operating conditions and possibly a fault
to be corrected. For example, prolonged lack of
compressed air will cause an excess build-up of dust
on the filters resulting in increased pressure drop.
Cleaning off-line with no flow usually restores the
filters to normal pressure drop.
4. Monitor exhaust.
5. Monitor dust disposal.
