Hog Slat Inc. Newton Grove, NC USA August 2021 8 Grow-FlexTM Feed System System Weight & Length Specifications Adequate support must be provided to prevent the tubes from sagging and support the weight of the Control Unit. The auger, tubes, and feed weigh approximately 6 lbs/ft. (9 kg/m). The Control Unit weighs approximately 80 lbs (36 kg.). Line lengths specified allow for two 45 degree elbows in the elevation. Reduce line length by 30’ (9 m) for each additional horizontal 90 degree elbow. For Tandem Systems, raise the horsepower one size over recommendations in the table below or reduce line length by 50’ (15.4 m). Note: If voltage supplied is 208 V, reduce the line lengths by 20%. Horsepower requirements are based on length of the GROW-FLEX Auger System and type of system installed (number of turns, tandem systems, etc). The charts included show maximum line lengths for GROW-FLEX Auger Systems plus maximum lengths for systems using Extension Hoppers. Model 55 Model 90 Motor Maximum Maximum Motor Maximum Maximum H.P.

When laying out the GROW-FLEX Auger Feed Delivery System, plan the system so that the auger tubes do not interfere with doors, windows, or other equipment. See page 12 for typical Bin-to-Building Placement Chart using various elevations and boots. 1. For the easiest installation and most trouble-free operation, locate the feed bin in a direct line with the GROW-FLEX Auger Feed Delivery System. The layout chart on page 10 provides some points of reference for bin placement according to the height at which the GROW-FLEX Auger tube enters the building. Remember, these are only examples. The layouts can be modified by changing the elbows, the tube sections, and /or the distance from the bin to the building. Locate the bin so that the GROW-FLEX Auger Feed Delivery System does not have to convey feed at an angle of more than 60 degrees from the horizontal to enter the building at the desired height. GrowerSelect considers a 45 degree elevation to be standard (the lower the angle, the more reliable the system).
