Color Module Fluidizing Plate Replacement
Replace the fluidizing plates if they become contaminated by dirty air,
clogged with fine powder particles, or damaged.
WARNING:
Wear a NIOSH-approved respirator or dust mask and safety
glasses or goggles when handling powder or cleaning powder off
equipment. Avoid getting powder on your skin. Wash with soap and water
only.
Preparation
1. Start the transfer pumps and pump the powder in the color module
hoppers back into the feed hopper. If the powder is contaminated, pump
it into a scrap container.
2. Remove the color module from under the fan section as described in the
Reclaim-to-Reclaim Color Change procedure in the Operation section.
3. Remove the grates, baffle, transfer pumps, and cartridge filters from the
color module. Refer to Cartridge Filter Replacement for instructions.
4. Remove all the powder from the color module hoppers. Vacuum the
hoppers and fluidizing plates. Wipe them clean with damp, lint-free
cloths. Do not use tack cloths.
Fluidizing Plate Replacement
1. See Figure 7-3. Unscrew the screws (6) on the clamping channels (5)
about 6 − 10 mm (0.25 − 0.375 in.) to clear the fluidizing plate gaskets (1).
Remove the outside clamping channels (5) (the inner clamping channels
are welded to the color module).
2. Slide the fluidizing pans (4), fluidizing plates (2), and gaskets (1) out
from under the color module.
3. Remove the fluidizing plates and baffles (3) from the pans. Discard the
old plates and gaskets.
4. Clean the pans, baffles, diffuser plates, the removable and fixed
clamping channels, and the color module hopper flanges.
5. Install the baffle plates in the fluidizing pans.
6. Install new fluidizing plates and gaskets on the pans.
7. Slide the pans and plates into the fixed clamping channels under the
color module. Install the outside clamping channels over the color
module and fluidizing pan flanges.
8. Tighten the clamping channel screws, using a torque wrench, to
2.8 N
D
m (2.1 ft-lb). Tighten the screws in a criss-cross pattern to avoid
distorting the flanges.
9. Install the cartridge filters, baffle, grates, and transfer pumps. Install the
color module under the base.
