How to Change The Tank Filter in A Nordson ProBlue Melter

  1. Verify the new tank filter has the appropriate new o-rings.
  2. Turn the pressure off to the pump.
  3. Place metal bucket under the tank filter area to catch excess glue.
  4. Use a 5/8” wrench to slowly loosen the tank filter.
  5. If the tank filter assembly has a removable screen that unscrews at the filter bung, use a second wrench to unscrew the filter screen and drop the screen in the bucket.
  6. If all one piece, drop the complete assembly in the bucket.
  7. If using Keystone assembly with removable filter screen, remove any old o-rings and replace with the new o-rings.
  8. Apply o-lube to the o-rings before inserting the tank filter back into the melter.
  9. Screw the new filter assembly into manifold. Do not over tighten.
  10. Turn pump pressure on.
  11. Verify there are no leaks at the newly installed filter assembly.
