Symptom Cause
Solution
Perform a colored trace dust test to discover the source of
leak
Check for leaking gaskets, clean tube sheet to assure good
seal
Check temperature, use appropriate media or use dilution
air
Change media type or total area in cartridges
Leaking of cartridges (continued)
Consult Customer Service (1-800-479-6801)
Use pre-coat dust for start-up
Check for adequate airflow at collection points and hoods
(adjust)
Allow more time for collector to build dust cake; it may take
weeks
Reduce cleaning time and frequency
Change media type or surface area in filter cartridge
Use pre-coat to assist in the capture of other forms of dust
Insufficient filter cake formation
Consult Customer Service (1-800-479-6801)
Check programming on controller and adjust accordingly
Check and calibrate photohelic or magnehelic gauge
Increase the amount of time between pulse events
Decrease the duration of pulse events
Remove bypass setting of controller
Increase the “High” set point on the controller
Refer to the appropriate section in manual for your type of
controller
Cleaning cycle too frequent
Consult Customer Service (1-800-479-6801)
Measure air temperature in collector and compare to design
Use dilution air to reduce temperature in collector (change
fans)
Install alternate media that can tolerate higher temperature
Temperature too high
Consult Customer Service (1-800-479-6801)
Replace cartridges with correct filter media for application
Wrong filter media used
Consult Customer Service (1-800-479-6801)
Confirm correct placement of cartridges, prevent ramping of
filters
Confirm locking mechanism is in the closed position
Remove filters and clean tube sheet to assure a good seal
If cam-bars are bent, replace cam-bars
If cam-bars are not bent, replace support brackets for cam-
bars
Replace cartridges
