Draining Material
Allow the melter pump(s) to run until the material has drained from the
melter.
CAUTION: Do not feed charred material through the gun. Particles can
block the gun. Instead unscrew the hose and feed the material out through
the hose connection (Refer to section Installation).
If the Unit is Equipped with a Drain Valve (Option)
1. Place a container under the drain valve and open the ball valve.
2. Feed the material out of the drain valve and collect it.
3. Close the ball valve and dispose of the material properly according to
local regulations.
Cleaning Tank by Hand
Cold material can usually be peeled off of the sides of the tank (Refer to
Fig. 5-4). If necessary, first heat tank to material softening temperature,
approx. 70 °C / 158 °F.
NOTE: The inside of the tank is release coated. Do not use metallic tools to
clean. Do not use wire brushes! This could damage the release coating.

Tightening Fixing Screws
Heating and cooling that occurs during daily operation can cause the fixing
screws to loosen. Tighten screw as indicated in the table.
NOTE: Tighten fixing screws only using a torque wrench and when the
melter is cold.
