Flushing the Applicator
Before operating the system, the applicator must be flushed to remove
residue left over from factory‐testing. Install the nozzles after this procedure.
For information on installing nozzles, refer to Maintenance.
NOTE: This equipment is factory tested with Nordson Type R fluid
containing polyester adipate plasticizer. Certain adhesives may react with the
Type R fluid residue to form a solid gum that can be difficult to remove.
Consult with the adhesive supplier to determine the compatibility of the
adhesive with Type R fluid.
1. Disconnect or turn off the solenoid valve triggering device.
2. Turn on the melter and allow it to reach operating temperature. Refer to
the melter manual for the startup procedure.
3. Place a drain pan under all applicators.
4. Flush according to the type of applicator module being used:
For standard Applicators
a. Dispense hot melt material from the applicator by manually triggering
the solenoid valve(s).
b. Stop dispensing when the flow of hot melt material is clear and free of
residue.
