Introduction
This section covers basic repair procedures for the Colormax Engineered
powder coating system. Repair procedures for the feed center and other

Cartridge Filter Replacement
Use the following procedures to replace the afterfilter cartridge filters.
NOTE: Two people are required to replace the cartridge filters. One person
works from the pulse valve compartment, removing the cartridge filter
mounting hardware. The other person works in the filter compartment,
removing the old filters and holding the new filters up against the mounting
plate.
Cartridge Filter Removal
1. Shut down the powder coating system. Refer to Shutdown in the
Operation section for instructions. Shut off and lock out system
electrical power.
2. See Figure 7-1. Remove the access doors in the pulse valve and
cartridge filter compartments (1, 2).
3. Pull up on the T-handle on the draw rod (8) to hold the cartridge
filter (10) against the mounting plate (7) at the top of the filter
compartment.
4. Remove the nut (3), lock washer (4), flat washer (5), and mounting
bracket (6) from the draw rod. Save these parts for reuse.
5. Carefully lower the cartridge filter away from the mounting plate and out
of the afterfilter. The centering bracket (9) and draw rod will stay in the
cartridge filter.
6. Unscrew the draw rod and remove the draw rod and centering bracket
from the old cartridge filter.
