8. When a multi-story building is supplied by one auger solely, obtain total drop-out at each outlet.
A time clock MUST be utilized to ensure that all of the feeders are filled at the same time. In the last
hopper on every level, install a hopper level control.
9. With the straight-through tandem system, open only one tank slide at a time when feeding. Operating
the system with both unloader slides open is not recommended since horsepower consumption
increases considerably.
