Cleaning the Hopper
CAUTION: Hot surfaces. Always protect yourself from hot surfaces inside and
outside the dryer and drying hopper.
The hopper, spreader cone, and discharge assembly should be cleaned thoroughly
between material changes to prevent resin contamination.
1 Close the hopper slide gate.
2 Disconnect the hoses and remove the distribution box under the hopper
and drain the remaining material into a bucket.
3 Remove the spreader cone. Open the hopper door. Reach into the hopper.
Grasp the spreader cone tube, lift up slightly, twist and then push down to
release it. Tilt the cone assembly and pull it out through the hopper door.
4 Clean the spreader cone and the inside of the hopper. Make sure you also
clean the return air screen at the return air outlet of the hopper.
5 Repeat the steps in reverse order to reassemble the hopper before adding
material.
