Pulse Valve Replacement
Preparation
NOTE: Replace the pulse valves one at a time to avoid confusing which
wiring connects to which pulse valve.
1. Shut down the powder coating system. Refer to Shutdown in the
Operation section for instructions.
2. Shut off and lock out system electrical power.
3. Remove the pulse compartment access panels.
4. Disconnect the wiring from the pulse valve (4).
5. Unscrew the pulse valve from the nipple (2), then unscrew the nozzle (5)
from the pulse valve.
6. Clean the threads of the nipple and nozzle. Wrap 2−3 layers of new
PTFE tape around the threads.
7. Install the nozzle onto the new pulse valve.
8. Screw the new pulse valve assembly onto the nipple. Make sure that
the pulse valve nozzle points straight down into the cartridge filter.
9. Connect the wiring to the pulse valve.
