**FastDry™, FastDry™ Plus and Continuous Flow Bottom Unload: Additional supports are required around the center sump.

***For Recirculation devices: Use 18 Ga. supports with perforated flooring or 20 Ga. supports with Hawk Cut™ Flooring. Additional supports are placed around the center sump. Maximum grain depth is 20'. Sitrring machines are not recirculators; therefore, regular grain depths and tables may be used.
