2.

Make sure kettle burners and screed box burners are lit.

3.

Set Kettle Temperature Control to maximum temperature recommended by thermoplastic manufacturer.

NOTE: If the kettle is empty do not allow the kettle to heat for more than five minutes before adding thermoplastic.

4.

If the kettle has 50 lb or more of thermoplastic already inside, allow the kettle to reach maximum melting temperature recommended by thermoplastic manufacturer.

5.

Unlatch kettle cover, raise cover, rotate agitator crank to 9 o’clock position and hold at this position using the cover latch.

Once material has been completely melted, lower temperature to recommended material application temperature to prevent material from overheating.

10. Start the box burner three minutes before filling screed box with material.

11. Use torch to heat screed box and chute to application temperature if screed box and chute temperatures are low.

12. Release parking break and remove wheel chocks. ti15950a

ProMelt Overheating Protection

This unit has a built-in protective device to prevent damage from overheating. The kettle burners may automatically shut down if excessive temperatures are reached.

If this happens, allow the unit to cool down for 20-30 minutes or until main kettle burners (2) reignite and resume operation.

ti14123a

NOTE: The material gate is adjustable. The gate is factory set at a 0.5 in. (1.3 cm) gap. You can increase this gap for more material flow or decrease the gap for less material flow.

14. Do not overfill material in kettle. Overfill would be material higher than 5 in. (13 cm) below top of kettle.

5.0 in.
