The dump valve opens as soon as the “Press to Open Feeder” key is pressed. This easy feeder clean out option also serves as a means for emptying a batch that is held in the weigh hopper if the “Press to Open Weigh Hopper” key is pressed when the blender is stopped.

Touch the “Done” key to return to the recipe menu. After entering a recipe, the operator will restart the blending system, putting it back in normal operation.
