  • Page 40 4. O REM - G VR12 PERATION RAIN 4.8. G RAIN ACUUM PERATION ROCEDURE 8. The grain is conveyed into the GrainVac in a stream of air. As a consequence, it is necessary to allow some air to enter at the intake. This can be done by not completely filling or covering the end of the hose with grain.
  • Page 41 REM - G VR12 4. O RAIN PERATION 4.8. G RAIN ACUUM PERATION ROCEDURE 12. Do not allow water, snow or other forms of moisture to enter the machine. They can damage the inner working parts and cause plugging by caking up the material. If these do enter the machine, slow the feed rate by increasing the airflow for a time to allow the machine to clear itself.
  • Page 42 4. O REM - G VR12 PERATION RAIN 4.8. G RAIN ACUUM PERATION ROCEDURE Figure 4.11 Air Throttle Fully Open (Regular Crops) The machine generates heat through the action of the rotors.

  • Page 43 Three(3) hose caddies (see Figure 4.13) are standardly supplied with the GrainVac VR12 and can be attached to the bottoms of the hoses and tubes to enable these pipes to move across the bin floor with greater ease. As the intake hose gets longer, it will be necessary to allow more air to enter the intake hose to provide the necessary airflow.
  • Page 44 4. O REM - G VR12 PERATION RAIN 4.8. G RAIN ACUUM PERATION ROCEDURE 15. As the bin is emptied, there will be grain on the floor and in the corners. Attach the standing floor sweep (see Figure 4.14) onto the end of the steel flex hose (which was attached to the straight aluminum tube).
