Adhesive Tips: How To Purge and Clean Nordson Glue Melter 

How To Purge and Clean Nordson Glue Melter
Step 1 - Decrease Air pressure
Lower the glue pump’s air pressure to 0 psi by using a 5 mm hex wrench to turn the pressure adjustment screw counterclockwise until it stops.
Step 2 - Purge the unit filter
Lower the drain chute and place a suitable container under the drain valve.
Open the drain valve until a steady flow of glue starts pouring into the container.
When the glue flow starts to lessen, increase the glue pump's air pressure to 10 psi. Pour until you no longer see char particles.
Your unit filter is now clean. You can close the drain valve and set the air pressure to where it was originally.
