4.3.2 DIGITAL PULSE CONTROL (DPC)
PANEL
the DPc Pulse control Panel is set for “Pressure
Switch” or “PS” pulse mode. With the DPc control,
the desired pressure can be maintained by adjusting
the high and low set-points on the panel. the factory
setting is 3.0 (high set-point) and 2.5 (low set-point).
this allows a 0.5” “deadband” and the pulse system will
maintain the desired pressure. the high and low set-
points on the DPc can be adjusted as the filters season
and continuous pulsing occurs. adjust upward in 0.5”
increments until pulsing stops. continue adjustments,
when required, until the high set-point reaches 5”.
no further adjustments should be made over 5” w.g.
5. SERVICE
Before servicing dust collector:
• Wear appropriate protective clothing when servicing
dust collector.
• Disconnect and lockout electrical power to the unit
and control panel.
• Close off and slowly bleed the compressed air
supply from the air manifold reservoir. air manifold
reservoir pressure should be reduced to 0 PSiG
(0 Bar).
• Collected dust may be hazardous. Consult proper
authorities for handling and disposal.
• Collected dust may be a potential fire hazard.
Welding, grinding or operations involving open
flames should not be performed without fire
protection measures in place. refer to Section 1
of this manual for additional precautions.
• Disposal of collected dust must be according
to federal, state and local regulations and all
appropriate authorities.
5.1 CARTRIDGE FILTER REMOVAL AND
REPLACEMENT
Protura
®
nanofiber filters are the only replacement filters
which provide the highest level of performance expected
from the Sfc Dust collector.
replacement cartridge filters should be ordered when
the differential pressure is consistently above 5” w.g.
(127 mmaq) or system airflow is inadequate and won’t
significantly recover with off-line (no fan pulse) cleaning.
to order filters, contact uaS at 888-515-8800.
TO REPLACE CARTRIDGE FILTERS
1. read and follow caution instructions in box above
before servicing your unit. Start with the top row of
QuickSeal doors. (figure 17)
2. tap the metal surface of each filter access door 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 filter access door is now in an
unlatched position. Lift the QuickSeal filter access
door upward until the door rods clear the side support
brackets. Pull the door away from the dust collector.
tilt the door cover away from the dust collector once
free from the support brackets to trap any dust on the
inside of the filter access door. Dispose of dust into a
suitable container. Place filter access door in a
safe place.
3. Move filter from side to side to break the gasket seal
between filter-to-filter-to-tubesheet locations. rotate
the filter 180° to allow the dust on top of the cartridge
filter to fall into the dust collector hopper.
4. Slide the filters out of the dust collector and transfer to
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 the area is dry after the
cleaning process is complete.
6. install new Protura
®
nanofiber cartridges into each
filter compartment, gasket end first. clean the filter
door gaskets and align 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
door cover plate support rod in the support brackets
(refer to figure 17). 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.
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 17.
if cam surface of the door handle is visible, QuickSeal
filter door assembly has been improperly installed.
7. the Sfc 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.
5.2 DUST REMOVAL
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).
