Flushing the Melter
Flush the melter at the following times to remove residue:
S before first-time operation of a new melter
S whenever the adhesive type is changed
S if a PUR adhesive is being used, before a melter shutdown that will
last longer than two days
WARNING! Risk of burns! New melters contain a small quantity of
low-viscosity test fluid. Test fluid may splatter when discharged under high
pressure. Before flushing the melter, ensure that the PCV is set to low
pressure.
Process a minimum of one reservoir volume of hot melt or flushing material
through the melter, hoses, and applicators. At some point, set the pressure
control to a low value and close the applicator(s) to flush the pressure control
recirculation loop.
