3. Check that filter retention brackets are properly
tightened to achieve proper filter seal.
4. All access panels should be sealed and secure.
5. Check that exhaust damper is set to the fully-closed
position.
6. Check and remove all loose items in or near the inlet
and outlet of the unit.
7. Check that all remote controls and solenoid
enclosures (if applicable) are properly wired and all
service switches are in the OFF position.
8. Check that all optional accessories are installed
properly and secured.
9. Turn power ON at source.
10. Turn the compressed-air supply ON. Adjust pressure
regulator for 90-100 psig.
11. Turn blower fan motor ON.
12. Adjust airflow with the exhaust damper, if equipped.
Excess airflow can shorten filter
life, cause electrical system
failure, and blower motor failure.
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.
NOTICE
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 psi.
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.
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.
2. Monitor pressure drop across filters.
Abnormal changes in pressure drop 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.
3. Monitor exhaust.
4. Monitor dust disposal.
