6.1 CARTRIDGE FILTER REMOVAL AND
REPLACEMENT (FIGURE 15)
The Supra-Series cartridge filters are the only
replacement filters that will provide the high level of
performance that is expected from the Supra-Pulse dust
collector.
Replacement cartridge filters should be ordered when
the differential pressure is consistently above 6" w.g. or
system airflow is inadequate. To order filters, call 1-800-
252-4647. The following procedure should be used to
replace the filters:
1. Start with the top access covers. Remove each
access cover by turning the knob counterclockwise.
Tilt cover back away from the unit when free from the
support yoke to trap any dust on the inside of the
access cover. Dispose of dust into a suitable
container. Set the cover aside.
2. Move the filter from side to side to break the gasket
seal between the filter and the tube sheet. Rotate the
filter 180 degrees to allow the dust on top of the
cartridge to fall into the dust collection hopper.
3. Slide the filter out of the unit along the support yoke
and transfer to a suitable disposal container. Repeat
this procedure for remaining filters.
4. Inspect the tube sheet and make certain the gasket
sealing area is free of dust to ensure proper sealing
of the new filter. Make certain the area is dry after
cleaning process is complete.
5. Install a new Supra-Series cartridge filter on each
support yoke, GASKET END first. Clean the access
cover gaskets and reinstall the cover onto the
support yoke. Tighten the knob until the outer door
gasket seats against the cabinet. Continue to tighten
the knob 1 1/2 turns. The maximum torque on the
door knob is 120 inch-pounds.
NOTE: The access cover must be securely tightened
to ensure compression of the filter gasket. Dust
leakage (bypass) can occur if the filter gasket is
not properly sealed.
6. The Supra-Pulse unit is now ready to be placed in
service. Reconnect electrical power and air supply.
Please follow initial start-up checklist to ensure
proper unit performance.
6.2 CARTRIDGE FILTER SEEDING
PROCEDURES
Before seeding the filters, remove any afterfilter
because a small amount of particulate will pass through
the cartridge filter initially. To begin seeding the filters,
turn the cleaning system “off,” then turn unit “on.”
Introduce the seeding material by slowly and gently
shaking the material next to an extraction hood or into
the drum lid opening (remove drum) where it can be
drawn into the unit. The seed material should be drawn
in as a continual “cloud,” trying to avoid any dust “slugs.”
Continue to feed the seeding material until the reading
on the filter monitor gauge increases by approximately
1" w.g. Replace the afterfilter, if applicable, and the dust
storage drum, if removed, before starting the unit.
6.3 DUST REMOVAL
NOTE: Do not let the dust storage drum overfill. This
can cause poor collector performance and
require an extensive clean-up due to overflow
of dust when removing the container(s).
Turn off the dust collector and empty the dust storage
drum an necessary to prevent dust from accumulating in
the hopper. Empty the dust storage drum when 2/3 full.
If the hopper has a slide gate, close the gate before
removing the dust storage drum. The collector fan does
not have to be shut off if this slide gate procedure is
followed. Remember to open the slide gate when the
dust storage drum is replaced.
6.4 SERVICING THE COMPRESSED AIR
COMPONENTS
1. The compressed air system should be periodically
checked to ensure clean, dry air is delivered to the
Supra-Pulse. Check the compressed air components
and service as recommended by the manufacturer.
2. Periodically check the air manifold(s) for
contaminants and drain any condensed liquid
from the manifold.
3. With the compressed air supply turned on, check the
cleaning valves, solenoid valves and the tubing
between them for any air leakage. Replace any
components that are defective.
!
CAUTION
Shut off and slowly release the pressure in the
compressed air piping and/or the Supra-Pulse
compressed air reservoir manifolds prior to servicing
this equipment.
