6.0 SERVICE
MAINTENANCE
WARNING
All maintenance must be done with the
electrical power locked-out and tagged-out, and
the compressed air supply line bled, locked-out
and tagged-out. Failure to do so could result in
death or serious injury from electrical shock,
unintentional actuation of a component, or from
the venting of trapped compressed air.
6.1
Replacing Filter Cartridges
WARNING
Failure to wear properly fitted and maintained,
NIOSH approved respirator and eye protection
when servicing dust laden areas of the dust
collector could result in serious eye irritation
and lung disease or death. Toxicity and health
risk vary with type of media, and dust
generated by blasting. Identify all material that
is being removed by blasting, and obtain a
Materials Safety Data Sheet for the blast media.
6.1.1
Empty the dust drawer, and return the drawer to
its position.
6.1.2
Open the top access door.
6.1.3
Remove the nuts securing the cartridge hold-
down plates.
6.1.4
Remove the hold-down plates and venturi tubes.
6.1.5
Remove cartridges from the top. A small amount
of force may be necessary to loosen the seal of the
cartridge gasket.
6.1.6
When cartridges are removed, clean the inside
of the collector to remove loose or hardened dust,
particularly from the cartridge sealing surface, and the
clean side (top side) of the cartridge sheet.
6.1.7
Install new cartridges; center each cartridge,
install venturi tube, and secure with hold-down plates.
6.1.8
Inspect the access door gasket, replace if worn
or damaged. Close the access door and secure.
6.1.9
Reset timer OFF time to 40 seconds.
6.1.10
Reset pressure to 70 psi.
6.1.11
Season cartridges per Section 6.2.
6.2 Seasoning
Cartridges
6.2.1
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.
6.2.2
Operate
the
collector
without pulsing (sequence
switch off) until the differential pressure gauge reads four
inches (4" w. c.).
6.2.3
After the differential pressure is reached, set the
timer OFF time to 40 seconds, and set the pulse pressure
at 70 psi.
6.2.4
Turn the sequence switch ON to start the pulse
cycle. See Section 4.2.
7.0 TROUBLESHOOTING
WARNING
Shut down the collector immediately if dust is
emitting from the exhauster. Check to make
sure 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
.
7.1
Collector Not Pulsing
7.1.1
Check the manifold pressure gauge. If the
reading is low, check the regulator adjustment, and
compressed air supply, look for a closed supply valve.
7.1.2
Check to make sure the sequence switch is not
turned off.
7.1.3
Check the fuse in the sequence control panel.
Replace as necessary.
