Recommended Cleaning Procedure for Powder Contact Parts
Nordson Corporation recommends using an ultrasonic cleaning machine
and Oakite r BetaSolv emulsion cleaner to clean spray gun nozzles and
powder path parts.
NOTE: Do not immerse the electrode assembly in solvent. It cannot be
disassembled; cleaning solution and rinse water will remain inside the
assembly.
1. Fill an ultrasonic cleaner with BetaSolv or an equivalent emulsion
cleaning solution at room temperature. Do not heat the cleaning
solution.
2. Remove the parts to be cleaned from the gun. Remove the O-rings.
Blow off the parts with low-pressure compressed air.
NOTE: Do not allow the O-rings to come in contact with the cleaning
solution.
3. Place the parts in the ultrasonic cleaner and run the cleaner until all
parts are clean and free of impact fusion.
4. Rinse all parts in clean water and dry before re-assembling the spray
gun. Inspect the O-rings and replace any that are damaged.
NOTE: Do not use sharp or hard tools that will scratch or gouge the smooth
surfaces of powder contact parts. Scratches will cause impact fusion.
