Most mists present safety and health hazards that require precautions. Wear eye, respiratory, head and other
protection equipment suitable for the type of mist.
Use proper safety and protective equipment when removing contaminants and filters.
Dirty filters may be heavier than they appear. Use appropriate lifting methods to avoid personal injury and/ or property
damage.
Turn power off and lock out all power before performing service or maintenance work.
Do not operate with missing or damaged filters

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 pressure drop across filters.
Abnormal changes in pressure drop may indicate a change in operating conditions and possibly a fault to be corrected. If the
pressure gauge is in the red zone, the second-stage filter wrap or third-stage filter cartridge may need replacement. In some
applications, it may be necessary to replace the second-stage filter wrap two to three times during the life of a single, third-
stage filter cartridge. To detemine if the second-stage filter wrap needs replacing, install a clean wrap, restart the collector, and
check the pressure gauge reading. If the gauge is now in the green zone, continue to operate the collector with the new wrap.
If the gauge still reads in the red zone, the filter cartridge needs replacement.
3.
Monitor exhaust. Exhaust should remain visually clean throughout filter life. If leaks are visible, check the filter cartridge and
optional HEPA filter for positive gasket seals.
4.
Monitor hopper drainage. If slow or stopped, check hopper for obstructions and clean as necessary. Check first-stage filter and
clean as required.
5.
Monitor second-stage filter wrap.
During any service activities there is some potential for exposure to the mist in the collector. Most mists present
safety and health hazards that require precautions. Wear eye, respiratory, head and other protection equipment
suitable for the type of mist when performing any service activities.
Use appropriate access equipment and procedures. Note the standard collector is not equipped with access
platforms unless noted on the specification drawings.
LOCK-OUT all energy sources prior to performing any service or maintenance on the equipment.
Electrical service or maintenance work must be performed by a qualified electrician and comply with all applicable
national and local codes.
