AW16000 - Instruction Manual
New cartridges must be seasoned. Cartridges are seasoned by letting a dust layer develop on the outside surface
of the filter media. The dust layer protects the filter cartridge, and enhances the filtering efficiency.
Cleaning will be done automatically. When differential static pressure indicator (parameter section high alarm,
page 11) indicates high-pressure alarm, the high alarm signal will blink. Cartridges need to be replaced at that time
WARnInG :
shut down the collector immediately if dust is emitting from the exhauster.
Check that cartridges are correctly seated and not worn or damaged. Prolonged breathing of
abrasive dust and blasting by-product dust could result in serious lung disease or death. Short
term ingestion of toxic dust such as red lead, poses an immediate danger to health. Identify all
materials that are to be removed by blasting, and obtain a Materials Safety Data Sheet for the
blast media.
Collector not Pulsing
®
Check the manifold pressure gauge. If the reading is low, check the regulator adjustment,
and compressed air supply, look for a closed supply valve.
®
Check to make sure the sequence switch is energized.
®
Check that the pulse system program as not been change.
®
Check the fuse in the main electrical box. Replace as necessary.

Check the diaphragm valve. With the compressed air turned off, remove the cover screws, inspect the
diaphragm and clean the bleed port.
®
Check for blockage in the tubing to the diaphragm valves.
Pulse is a steady stream of air instead of a pulse.
®
Check for a leak in the tubing between the diaphragm valves and solenoid.
®
Solenoid is remaining in open position. Check continuity, clean, replace.
