4. Any side of a square/rectangular opening shall have a maximum length of 18" and a circular opening shall
have a maximum diameter of 24".
3.6. Guidelines for Side Draw Use
1. Intended for use with dry grain only. Do not use a side draw with poor flowing grain products
2. Only one side draw may be used at one time.
3. If two side draws are used, they must be placed 180 deg apart from each other in the same ring.
4. Side draws are not considered the primary outlet. Standard center sumps and conveyors must be installed.
After side draw use, unload from the center, then intermediate gates and sweep.
5. Side draw will leave grain in a sloped position creating off center loads. Before refilling, unload through the
center sump so that the grain reaches equal wall heights all around the bin. Grain must be level or in a cone
down position before adding more grain.
6. Do not unload from the side draw and center sump at the same time.
7. These systems are not intended for simultaneous fill and discharge.
3.7. Critical Assembly Requirements
To ensure a successful, safe and reliable outcome you must comply with the following assembly techniques and
practices:
1. Comply with all local code and jurisdictional requirements applicable to your side draw discharge
installation.
2. Design and build foundations with the necessary strength for the loads they must support, and for local soil
conditions. Westeel foundation guidelines are based on specific stated conditions and may not be applicable
to local conditions.
3. Your foundation must provide uniform and level support to the structure being supported. Surface
imperfections causing gapping must be remedied. This may involve, but not be limited to a) grouting under
the bottom ring of a non-stiffened bin or tank, and b) shimming under the uprights of a stiffened bin or
tank, or under the legs of a hopper.
4. Make sure that the proper hardware is utilized for all bolted connections. If a shortage occurs, do not
substitute. Take the necessary steps to obtain the proper hardware. Make sure nuts are tightened to the
required torque values as specified in the appropriate assembly manual.
5. Comply with all assembly instructions provided in the appropriate assembly manual to make sure your
whole side draw discharge is constructed safely.
Important: Do not deviate from the wall sheet and upright
layouts provided.
6. Before anchoring your structure to its foundation, make sure the structure is round. The maximum variation
from perfect roundness is 3/4" on the radius. Locate anchor bolts toward the outside of the anchor bolt
holes (away from the circle) to permit the incremental expansion that can occur with the initial filling.
7. When installing roof stiffening rings, if it is necessary to shorten the stiffening ring tubes, shorten them as
little as possible. Initially the nuts on the expanders should be centered and as close together as possible.
When tightening, share the amount of take-up between expanders such that the nuts remain centered, and
the amount of engagement between all expanders on the same ring is equalized.
8. If extending an existing bin or tank, ensure that the foundation is adequate for the increased loads it must
support.
