Sfc
cartridge Dust collector
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 gate, close the slide gate before servicing
the dust storage drum(s). the dust collector fan and
compressed air cleaning systems do not have to be
turned off if the hopper slide gate is closed prior to
servicing storage drums. remember to open the slide
gate when the dust storage drum is replaced.
5.3 SERVICING THE COMPRESSED AIR
COMPONENTS
Shut off and slowly release the pressure in the
compressed air piping or the Sfc compressed air
manifold reservoir prior to servicing this equipment.
1. the compressed air system should be periodically
checked to ensure clean, dry, oil-free air is
delivered to the Sfc dust collector. check the
compressed air components and service as
recommended by the manufacturer.
2. Periodically check the dust collector air manifold
reservoir(s) for contaminants and drain any
condensed liquid from manifold reservoirs.
3. With the compressed air supply turned on, check
the diaphragm valves, electronic solenoid valves
and interconnecting tubing between both devices
for any air leakage. replace any components that
are defective or worn.
5.4 SERVICING THE DIRECT DRIVE
BLOWER AND MOTOR SYSTEM
ELECTRIC SHOCK HAZARD
all electrical work should be performed by a qualified
electrician in accordance with local electrical codes.
Disconnect electrical power before installing or
servicing any electrical component.
refer to blower assembly Installation and Operation
Manual provided with blower assembly for servicing
requirements.
5.5 SERVICING CARTRIDGE MEDIA
Before replacing cartridges, try down time (fan off) to see
if system recovers. if upon restart, collector S.P. is 2-1/2”
(63 mmaq) to 3” (76 mmaq) and it takes several days to
work back up to over 5” (127 mmaq), there is still “life”
left in the cartridges. if upon restart, 4 hours later S.P.
is back over 5” (127 mmaq), it is time to change out the
cartridges.
5.6 SERVICING OPTIONAL RETURN AIR
SAFETY FILTERS (HEPA/ASHRAE)
Periodically check the pressure drop across the return air
safety filters. replace when the differential pressure drop
exceeds 2” w.g. (51 mmaq) for aSHrae filters and 3”
w.g. (76 mmaq) for HePa filters.
