Troubleshooting guide

TO REPLACE CARTRIDGE FILTERS
(refer to Figure 19):
1. Read and follow caution instructions in Section 6
before servicing dust collector. Start with the top row
of QuickSeal doors.
2. Tap the metal surface of each door cover to remove
collected particles from the inner door gasket. Pull
the QuickSeal door handle away from the dust
collector until the handle makes a 90° angle with the
door cover. The door assembly is now in an
unlatched position. Lift the QuickSeal filter door
assembly upward until the door rods clear the side
support brackets. Pull the filter door assembly away
from the dust collector. Tilt the filter door cover away
from the dust collector once free from the support
brackets to trap any dust on the inside of
the access cover. Dispose of dust into a suitable
container. Place filter door assembly in a safe place.
3. Move filter from side to side to break the gasket
seal between filter-to-filter and filter-to-tubesheet
locations. Rotate filter 180° to allow the dust on top
of the cartridge filter to fall into the dust collector
hopper.
4. Slide the filter out of the dust collector and transfer
to a suitable disposal container. For double filter
configuration units, grab and pull forward the filter
extraction tool by the rod handle located between the
filter support tracks. The extraction tool is designed
to move the rear filter 18" (45 cm) away from the
tubesheet to ease removal of the filter. Place the
second cartridge filter into a suitable disposal
container. Repeat this procedure for the remaining
filters.
5. Inspect the tubesheet and make certain the gasket
sealing area is free of dust to ensure proper sealing
of the new filter. Make certain area is dry after
cleaning process is complete.
6. Install a new Supra-Max series cartridge filter(s) into
each filter hole, gasket end first. Clean the filter
access door gaskets and align filter door assembly
with door rod support brackets on the dust collector.
Door handle must be placed at a 90° angle to filter
access door prior to placing the filter door assembly
support rod in the support brackets (refer to Figure
19). The flat surface of the door handle should be
facing downward. To close the filter access door,
push the door handle upward, toward the unit.
7. The Supra-Blast dust collector is now ready to be
placed back in service. Reconnect electrical power
and air supply. Please follow the initial start-up
checklist to ensure proper unit performance.
6.2 CARTRIDGE FILTER SEEDING
PROCEDURES
Before seeding the cartridge filters, remove any
afterfilter(s) since a small amount of particulate will
initially pass through the cartridge filters. To begin
seeding filters, turn cartridge filter cleaning system off,
then turn fan system 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 dust collector. The
seed material should be drawn in as a continuous
“cloud,” trying to avoid excessively heavy dust clouds.
Continue to feed the seeding material until the reading
on the dust collector differential gauge increases by 1"
w.g. (25 mmAq) or one to two pounds of seed material
per filter have been added. Replace or re-install the
afterfilter and the dust storage drum before operating
the dust collector.
6.3 DUST REMOVAL
Turn off the dust collector (power to fan system and
compressed air to cleaning system) and empty the dust
storage drum as necessary to prevent dust from
accumulating in the hopper(s). Empty the dust storage
drum(s) when two-thirds full. If the hopper has a slide
!
CAUTION
Do not let the dust storage drum overfill. This can
cause poor dust collector performance and require
extensive clean-up due to the overflow of dust when
removing the collection container(s).
!
WARNING
The QuickSeal filter access door handle must be in a
perpendicular orientation to door surface prior to being
closed. A flat solid section of door handle will be
visible when door assembly is in the properly closed
position (refer to Figure 19).
!
WARNING
If cam surface of the door handle is visible, QuickSeal
filter door assembly has been improperly installed.
