Planning
2.Lay out the system as straight as possible. Avoid extra elbows and curves by locating the feed bin in line with
the feeders. One horizontal 90 degree turn is permissible inside the building. 180 degree turns are not
recommended under any conditions.
If additional turns or elbows are required, use an Extension Boot. Remember: one 90 degree elbow
requires the same power as 30' (9.1 m) of straight line.
3.Plan the system so that the auger tubes are directly over the feeders or hoppers to be filled, if possible. The
drop tubes may be angled to a maximum of 45 degrees from the vertical if necessary. At angles greater than
45 degrees, bridging in the drop tubes may occur.
4.The control unit must be located over a feeder or hopper that will require as much or more feed than any of
the other feeders or hoppers. If frequent filling is desired, mount the drop tube switch or hopper level switch
low so that this feeder or hopper will have a low feed level. This allows the feeder to call for feed more often,
the system will restart, and the other feeders will be refilled sooner.
5.Do not locate outlet drops on or just before an elbow. Install the drop after the elbow so feed will cushion the
auger through the curve. If there is some reason why the outlet drop cannot be moved, it must have some
"feed bypass" to cushion the auger through the elbow.
6.Avoid horizontal left-hand turns if possible. The elbow in a left-hand turn is not cushioned by the feed and
will wear faster. On systems with a 90 degree horizontal left-hand turn, reduce the stretch to reduce wear.
NOTE: A rule of thumb for left-hand turns is to reduce stretch to 6" per 50' (150 mm per 15 m) of auger
on initial installation. After the system has been broken in, it may be necessary to increase the
auger stretch to prevent auger surging.
7.On any Extended Length System, balance the power requirements between the power unit that takes feed
from the bin and the power unit on the Extended Length System.
To do this, determine the total length of the system and divide by two. Subtract 20' (6.1 m) from the standard
system and add 20' (6.1 m) to the extended system.
Example: On a 240' (73 m) system, the center of the system would be 120' (36.5 m). Subtract 20' (6.1 m)
from standard system, and add it to the extended length system. The first power unit should be located
approximately 100' (30 m) down the system. Locate the second power unit approximately 140' (42.7 m)
from the first power unit.
