Hog Slat Inc. Newton Grove, NC USA August 2021 16 Grow-FlexTM Feed System 6. When connecting auger tubes to unloaders inside of building, it is also recommended to cut a short section of auger tube approximately 12” long and attach the belled end of tube to unloader outlets. Do not connect elbow tubes directly onto unloaders. 7. Dry-fit all parts. When satisfied that elbows and tubes fit together smoothly, glue with PVC cement according to the following instructions. The auger tubes and elbows for the GROW-FLEX Auger systems are made of specially formulated PVC tubing. Use the PVC solvent cement to make strong, reliable bonds. FOLLOW DIRECTIONS ON THE CAN FOR SAFE HANDLING OF CEMENT. a. Be sure tube is cut off squarely. Remove burrs from outside and inside the end of the tube. b. Dry fit all parts. Tube should fit inside belled end of next tube to full depth without excess force. c. Clean surfaces to be joined. SURFACES MUST BE FREE OF DIRT OR GREASE! d. Apply a generous coat of cement to both the inside of the belled end and outside of the other tube. Be sure cement covers all of the joint area so there are no bare spots. e. Quickly join the tubes, giving them a twisting motion to bring them into alignment as they are joined. f. Keep pressure on the joint until the PVC cement sets up. 8. ALL TUBE JOINTS EXPOSED TO MOISTURE AND WEATHER MUST BE SEALED OR CAULKED TO WATERPROOF THEM IN ADDITION TO CEMENTING OR CLAMPING THE JOINT! 9. If there is more than 15 feet (4.5 meters) of auger tube between the boot and the building, provide additional support for the tubes so that the boot does not have to carry the weight of the auger. Extra support can be achieved with cables or chains fastened to the bin legs and auger tube. 10. Install the remaining tubes in the system AFTER the outlet holes have been located and cut. The auger tubes should be cemented using PVC cement supplied. NOTE: The tubes can be joined by cutting off the belled ends and fastening tubes together with tube connectors if there is some reason why permanent installation is not desired. (Tube Connectors are not standard equipment and must be ordered separately for this type of installation). Supporting the System-Inside the Building Support the auger tubing with chain and “S” hooks every 5 feet (1.5 m). The system should be restrained from swinging by using chain and “S” hooks to brace the auger tube, every 20 feet (6 m). Horizontal elbows need to be supported in at least two places. Chain, screw hooks, and “S” hooks are supplied as a suspension kit for supporting the equipment. Keep the line as level and straight as possible. If Drop Feeders, Extension Hoppers, Outlet Drops with long angled Drop Tubes, or other loads are imposed on the system, extra support must be added at that point. Power Units require extra support to resist the twisting encountered when the motor starts and stops.
