• Installation of multiple systems may require additional wind rings and must be placed a minimum of
90 degrees apart. Installation of multiple systems requires approval of GSI.
• Sidedraw systems are intended for use with dry, flowable grain. Sidedraws are not to be used for
poorly flowing products. This is not unique to GSI bins and flume systems, but is a general rule for
such systems.
• In multiple system installations, only one sidedraw may be used at any one time.
• Filling must not be occurring at the same time as grain is being withdrawn through the sidedraw
flume system.
• Prolonged storage of grain in the sloped condition produced by sidedraw discharge may accelerate
differential settlement and result in deformations of the bin. After using the sidedraw system, the
sloped grain must be returned to a near level condition by use of the center discharge. Leveling of
the grain should also allow more even consolidation of foundation and fill soils and produce more
even settlement of the bin.
• If past experience or geotechnical investigations indicate significant foundation level soil variations or
a site propensity toward differential settlement, sidedraw usage may be prohibited or severely
restricted. In this situation the use of a flume system should be reviewed with geotechnical consul-
tants or the foundation engineer.
• Before installing, determine if bin design is a two post stiffener (D) or a three post stiffener (E) configu-
ration. See the following figures.
• Only install baffle chutes and discharge chute between the post stiffeners (D and E).
• Do not install a discharge chute on a vertical seam.
• A discharge chute should be installed at the standard height (F).
