14. After the bin draw down is complete and the grain no longer flows into the intake
hose, add the straight aluminum tube to machine and move the steel flex hose into
the bin to pick up the majority of the grain pile (for this reason, the GrainVac is also
the ideal machine to clean up grain piles in the open or on a pad). In some cases it
may be necessary to combine these two hose options (see Figure 4.12) to obtain
the best performance. As the bin nears empty, additional lengths of hoses & tubes
will be required. Attach an additional steel tube or flex hose as required for the job to
be done. 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.
