6.4 Operating Checks
1. Monitor exhaust. Exhaust should remain
visually clean. If a dust leak develops, it will
be noticed as a visual puff of dust
immediately after a cleaning pulse.
2. Monitor filter cartridge pressure drop.
Stable pressure drop is generally 3 to 4-
inches water gauge on a Magnehelic or
Photohelic for seasoned filter cartridges, but
1 to 6-inches water gauge is considered
normal.
7.0 Service
• Disconnect electrical power before
servicing any electrical components.
• Shut off and bleed compressed air
supply before servicing any compressed
air components.
• No welding should be performed inside
the unit without fire protection.
NOTE
At initial start-up with any new filter
cartridges, the fan motor may overload
because of airflow higher than design level.
If this happens, partially close a volume
control damper and check blower fan
motor amp draw.
CAUTION
7.1 Filter Cartridges
(See Figure 5)
7.1.1 Filter Cartridge Removal
When changing the filter cartridges, start at the
top access ports of the unit first, so that the dust
which falls down into the hopper does not have
open access ports below or does not fall on
newly installed filter cartridges.
1. Remove access cover and set aside.
2. Move the filter cartridge to break the gasket
seal between the filter element and the
element panel sealing surfaces. Rotate the
filter cartridge slowly half a turn to dump
any loose buildup of dust off the top of the
filter cartridge. Slide the filter cartridge out
of the front of the dust collector.
• Turn off and lock out power so that the
fan cannot be started and pulsing can
not start.
• Dust-laden filter cartridges may be
heavy and difficult to handle.
