Cartridge Filter Replacement
NOTE: Two people are required to replace the cartridge filters. One person removes
hardware from above the cartridge filter. The other person removes the old filters and
holds the new filters up against the mounting plate.
Removing the Cartridge Filter
See Figure 8-18.
WARNING: Relieve system air pressure and lock out the air supply before performing
the following tasks. Failure to observe this warning may result in personal injury.
1. Remove the pulse valve and cartridge filter access panels (1, 2).
2. Pull up on the T-handle on the draw rod (8) to hold the cartridge filter (10) against the
mounting plate (7).
3. Remove the nut, lock washer, flat washer, and mounting bracket (3, 4, 5, 6) from the
draw rod. Save these parts for reuse.
4. Carefully lower the cartridge filter away from the mounting plate and out of the filter
section. The centering bracket (9) and draw rod will stay in place.
5. Unscrew the draw rod and remove the draw rod and centering bracket from the old
cartridge filter.
Installing the Cartridge Filter
See Figure 8-18.
1. Thoroughly clean the sealing surface on the underside of the mounting plate (7). A
dirty surface will prevent the cartridge filter gasket from sealing properly and allow
powder to leak into the fan section.
2. Remove the new cartridge filter (10) from its carton and inspect it for damage. Do not
use damaged cartridge filters.
3. Set the centering bracket (9) into the open end of the new cartridge filter. Slide the
draw rod (8) through the centering bracket. Screw the draw rod into the bottom of the
cartridge filter.
4. Center the cartridge filter under the opening in the mounting plate. Use the draw rod
T-handle to pull up the cartridge filter against the mounting plate.
5. Install the mounting bracket (6) on the draw rod, making sure that the slots in the
mounting bracket slip over the T-handle.
6. Install the flat washer, lock washer, and nut (5, 4, 3) onto the draw rod. Do not tighten
the nut at this time.
7. Slip the ends of the mounting bracket into the locating slots around the filter opening
in the mounting plate.
8. Tighten the nut until the mounting and centering brackets are touching. This will
compress the gasket (11) and seal the cartridge against the mounting plate.
9. Install the pulse valve and cartridge filter access panels (1, 2).
