Nordson Adhesive Melter D16L

To avoid the problems that can occur when different hot melt materials are mixed or when hot melt char forms in the tank, clean the tank when:

- changing to a different type of hot melt

- excessive char builds up inside the tank

NOTE: The tank cleaning procedures provided in this section require that an appropriate flushing material be used.; The flushing material should be compatible with both the previous adhesive and the new adhesive, if applicable.

To clean the tank when changing hot melt

1. Operate the melter normally until the tank is empty.

2. Press the Pump key to stop the pump.

3. Allow the melter to heat or cool to the temperature recommended by the manufacturer of the flushing material.

4. While wearing the appropriate protective equipment, wipe any residual hot melt from the inside of the tank.

Warning: Only trained personnel should perform this procedure

Note: The pressure control valve screw is turned fully counterclockwise (at or near the valve’s lowest pressure setting) at the factory and then the lock nut is tightened.

Before starting, is the lock nut loosened?

Before placing the melter into routine operation, loosen the lock nut and adjust the pressure control valve to achieve the desired adhesive output rate for your manufacturing process.

With the line running and the guns dispensing adhesive, turn the adjustment screw on the pressure control valve
