Hog Slat Inc. Newton Grove, NC USA August 2021 6 Grow-FlexTM Feed System Selecting the System GrowerSelect Feed Delivery systems are designed to handle most common livestock and poultry feeds. We cannot guarantee satisfactory operation with all formulations. We suggest that you contact our Technical Service Department concerning the use of new or unusual formulations. GROW-FLEX Auger Feed Delivery Systems are the most versatile feed conveying systems available. Their ease of installation, reliability, low maintenance, and adaptability for many different applications, make them an indispensable part of any livestock feeding system. The GROW-FLEX Auger Feed Delivery System you choose should be based on the following; 1. Particle Size - Feed particles that are too large for the system will cause damage to the particles, excessive power requirements, and plugging of the system. 2. Moisture Content (18% maximum) - The moisture content of the feed, among other factors, determines the amount of buildup that will occur on the auger and auger tubes when conveying feed. Feeds with high moisture content (above 18%) will freeze if exposed to freezing temperatures. This type of feed tends to flow less easily causing higher power requirements. Feeds in High Roughage (HR) applications should not exceed 27% moisture content. The HR system uses a Model 75 Auger inside of a Model 90 Grow-Flex tube in order to allow more clearance between the auger and the wall of the tube. HR is used in applications where moisture of the feed exceeds 18% but not more than 27% and also for larger particle size not to exceed 3/8” x 3/4” (10mm x 20mm). 3. Feed capacities - Each size of GROW-FLEX auger delivers feed at a different rate. These rates should be matched to your feed requirements. An application that requires a large volume of feed to be moved should use a larger (i.e. Model 90 or HR) auger system or possibly two smaller auger (i.e. Model 55 or 75) systems. See page 7 for System Comparison information. 4. Running Time - Size the system so that the maximum operating time is four hours per day (24 hours). If your system operating times exceed four hours per day, contact your distributor or Hog Slat’s Technical Service Department. NOTE: The maximum allowable liquid molasses content for all GROW-FLEX Auger Feed Delivery Systems is 2% . At higher liquid molasses content or at moisture levels above the recommended limits, the auger tubes can become coated. This reduces the carrying capacity of the feed delivery system, causing eventual plugging of the system.

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).

Hog Slat Inc. Newton Grove, NC USA August 2021 9 Grow-FlexTM Feed System 2. Lay out the system as straight as possible. Avoid extra elbows and curves by locating the feed bin in line with the feeders. One horizontal 90 degree turn is permissible inside the building. 180 degree turns are not recommended under any conditions. If additional turns or elbows are required, use extension hoppers. Remember: one 90 degree elbow requires the same power as 30’ (9.1 m) of straight line. 3. Plan the system so that the auger tubes are directly over the feeders or hoppers to be filled as possible. The drop tubes may be angled up to a maximum of 45 degrees from the vertical if necessary. At angles greater than 45 degrees, bridging in the drop tubes may occur. 4. The control unit must be located over a feeder or hopper that will require as much or more feed than any of the other feeders or hoppers. If frequent filling is desired, mount the drop tube switch or hopper level switch low so that this feeder or hopper will have a low feed level. This causes the feeder to call for feed more often, the system will restart, and the other feeders will be refilled sooner. 5. Do not locate outlet drops on or just before an elbow. Install the drop after the elbow so feed will cushion the auger through the curve. If there is some reason why the outlet drop cannot be moved, it must have some “feed bypass” to cushion the auger through the elbow. 6. Avoid horizontal left-hand turns if possible. The elbow in a left-hand turn is not cushioned by the feed and will wear faster. On systems with a 90 degree horizontal left-hand turn, reduce the stretch to reduce wear. NOTE: A rule of thumb for left-hand turns is to reduce stretch to 1" per 50’ (25 mm per 15.2 m) on initial installation. Increase the stretch if necessary. If an extension hopper is used: A. Locate the hopper so there will not be any outlet drops on the short tube or elbow leading out of the hopper. B. The longer portion of the system with most of the outlet drops should follow the extension hopper. For example: in a 300’ (91.4 m) Model 75 System the distance from the bin to the extension hopper should be 100’ (30.5 m). From the extension hopper to the control unit should be 200’ (61 m) with most outlets placed on the 200’ (61 m) section. Refer to chart on page 8, for power unit requirements. C. NOTE: The lower part of the extension hopper can be turned 90 degrees to the left or right in relation to the top portion of the extension hopper. This allows the extension hopper to replace a horizontal elbow where both might be located in approximately the same position in the system. 7. Remember the following points when installing a Tandem System or Twin Tandem System: A. The Tandem bin arrangement uses one continuous auger. B. The Twin Tandem bin arrangement uses two separate augers and power units. C. Pour one level concrete pad for both bins (in either system). D. Position bins so that legs will not interfere with the GROW-FLEX Auger System (in either system). 8. Use the chart on page 8 to determine maximum line lengths and power unit requirements. 9. The minimum length specification for Grow-Flex auger on outside of building is: 15 feet for a single

Hog Slat Inc. Newton Grove, NC USA August 2021 13 Grow-FlexTM Feed System Installation Instructions for the GROW-FLEX Auger Feed Delivery System Install the equipment as specified in this manual. Failure to install as specified may cause damage to the equipment and/or cause personal injury or death. Take special notice of the warnings and safety decals on the equipment and in this manual. Always wear protective clothing and protective glasses when working with the equipment. Discarded materials, equipment, and boxes may be recycled. Recycle according to local and national codes. Unless otherwise specified, the Model 55, 75, 90, & HR Systems are installed similarly. All the systems are available with straight-out or 30 degree upper boots. Bin Location and Collar Information For easiest installation and trouble-free operation, locate the feed bin in a direct line with the GROW-FLEX Auger System. The layout chart provides some points of reference for bin placement according to the height at which the system enters the building. The bin collar is installed during bulk bin assembly. GrowerSelect bins have a welded collar. Bin Adapter Kits are available to modify existing bins so that the welded collar can be used. In addition, most other feed bin manufacturers have a collar available to be used with GrowerSelect GROW-FLEX Auger Feed Delivery Systems. Boot Installation 1. Insert the upper boot into the bin collar opening and turn it to line up with the direction that the auger line will go. The boot must be as far up into the opening as it will go. Use the holes in the ring for drilling guides and drill 11/32" (8.8 mm) holes in the upper rim of the boot. Attach the boot to the Bin Collar using the hardware provided. See Figure 1 for correct use of hardware to attach the boot. IMPORTANT: Failure to install the hardware as shown in Figure 1 may cause breakage of the boot body. Nylon hex nut must be used where shown below. Figure1.

Hog Slat Inc. Newton Grove, NC USA August 2021 14 Grow-FlexTM Feed System Boot Installation (Continued) 2. Attach the transfer plate to the lower section of upper boot. Use truss head bolts installed from the inside of the plate and place nylon washers under the nylon nuts as shown in Figure 1. 3. Insert the slide into the transfer plate slot so that it is in its operating position before bolting the slide shield in place. Use two hex bolts 5/16-18x3/4" and serrated flange nuts to secure the shield. 4. Bolt the lower boot (unloader) to the transfer plate using four 5/16-18x3/4" hex bolts and serrated flange nuts. Auger Tube Installation The GROW-FLEX Auger Delivery System includes two 45 degree elbows as standard equipment. These elbows are used to make the sloping portion of the auger line at the feed bin, and elsewhere in the system if necessary. If additional elbows are required, they should be ordered separately. Figure 2 shows how the elbow can be cut into shorter sections. 15 Degree Elbow……..16.5” or 419mm 22.5 Degree Elbow…...24.75” or 628mm 30 Degree Elbow……...33” or 838mm 45 Degree Elbow….......49.5” or 1257mm These dimensions are measured along the long, outside curve of the elbow. They do not include the belled end of the elbow in the measurement. Figure 2. Elbow Cutting Guidelines (Side View)

Hog Slat Inc. Newton Grove, NC USA August 2021 15 Grow-FlexTM Feed System 1. Determine where the entrance hole for the auger tube must be located on the building and cut a hole large enough to fit tubing. 2. Place provided seal ring (location #3 in Figure 3) and neoprene seal (location #4) over the straight end of the elbow (item #1 in Figure 3). Insert elbow with straight end into building entrance hole. Secure seals to outside of building with required hardware. Position and cut (if required) the elbow at desired length to ensure that auger inside building will be horizontal. Figure 3. Bin to building elbow and tube layout diagram (Side View) (Single & Quad Unloaders) 3. Model 75, 90, & HR: Slide the belled end of the auger tube item #2 over the outlet end of the unloader. (Recommendation: a short section of auger tube should be cut approximately 12” long and attach the belled end to unloader outlets.) A clamp is provided to secure the auger tube to the unloader. Attach bell end of additional auger tubes or elbow to short section of auger tube as required. Do not connect elbow tubes directly onto unloaders. Model 55: Install a straight section of Model 55 auger tube (approximately 12” long) over the outlet end of the unloader. Do not assemble the belled end of auger tube to the unloader. A clamp is provided to secure the auger tube to the unloader. Attach bell end of additional auger tubes or elbow as required. 4. Place the end of a straight section of tube inside the belled end of the elbow extending from building. Hold the straight section of auger tube so that it touches the elbow on the unloader side. Mark the spot where the tube aligns with the "unloader" elbow and cut the elbow at that point. 5. Place the belled end of the auger tube over the end of the elbow that was just cut, and hold the tube against the top elbow. Cut the auger tube long enough to fit inside the belled end of the elbow in the building. Figure 4 shows the direction the auger is to run in relation to the belled end of the tube. (Note: some installations may only require auger tubes and a single elbow which enters the building.)

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.

Hog Slat Inc. Newton Grove, NC USA August 2021 17 Grow-FlexTM Feed System Use all of the “ears” on the gearhead as well as the suspension points provided on the HS593 Control Unit Box to support the Power Unit. Adequate chain and “S” hooks are provided with each system to properly support it. Other means of supporting the system are permissible as long as the system receives the correct support and the auger tube is not dented or flattened. Alternative support systems must allow for expansion and contraction of the auger tubes. When the auger tube passes through a sidewall or partition, especially where it enters the building, the opening should be made large enough so the auger tube can be supported without resting on the wall. If the auger tube rests on the wall or partition, the auger tube may flatten out or become kinked causing excessive wear. See Figure 6. Figure 6. Faulty Tube Installations (Side View) Supporting the System Outside the Building Some systems require additional support to avoid sagging auger tubes. This support must be adequate to support the weight of the auger tubes filled with feed. Special attention should be given to avoid excessive pressure from the auger being transferred to boot. Auger tube kinked because the supports are not high enough to keep the weight of the auger tube off the wall. Tube pinched because auger tube is not in line with hole in wall. Auger tube flattens because supports are too far away from each side of wall.

Hog Slat Inc. Newton Grove, NC USA August 2021 30 Grow-FlexTM Feed System HS529 Hopper Level Control Part List · Wiring · Installation Overview: The HS529 Hopper Level Control is a universal control intended to be used with any conveying system that carries free-flowing feed. The control will automatically start or stop the fill system as the feed level pressure against the paddle assembly changes. Controls may be used in more than one hopper to ensure that no hopper runs out of feed before the control unit hopper requires feed. In applications where more than one control unit is used, the Control Units must be wired in Parallel so that any unit can start the system. The HS529 is suitable for use in both Poultry and Hog applications. Poultry Applications Hopper Level Control installed in the end or in last hopper of Delivery System should be installed Low.

Hog Slat Inc. Newton Grove, NC USA August 2021 31 Grow-FlexTM Feed System Hog Applications For the majority of Hog Installations, the Hopper Level Control is installed in the last hopper that is located at the end of the Delivery System. Installation: The HS529 Hopper Level Control should be installed in the last hopper or feeder which is located at the end of the delivery or fill system. The unit should be mounted low in the hopper or feeder so the fill level in the control hopper will be lower than the others. This will cause the fill system to cycle more frequently ensuring a proper feed level in every hopper or feeder. It will also provide a reservoir of feed in the system if another control hopper calls for feed. The feed drop tube should be positioned so that feed is delivered to the center and near the top of the control in front of paddle. Drop tubes and other control units should be positioned high in other hoppers or feeders so that they will fill but not overflow. Important: The HS529 must be mounted vertically to ensure the proper movement of the switch and paddle assembly. HS529 Hopper Level Control Mounted Vertically Determine the desired placement of the Control Unit and drill (2) 9/32” (7.2mm) diameter holes using the Mounting Bracket as a guide to determine hole spacing. Assemble the mounting bracket using the supplier 1/4-20 hex bolts and lock nuts. (For those applications where there is not a suitable vertical surface on the hopper or feeder; the Mounting Bracket should be bent or formed to ensure the Control unit is completely vertical when installed into the Mounting Bracket.) Install the Control Unit into the mounting bracket. Note: The mounting bracket bolted directly to the Control Unit can be shifted between the two sets of screws to achieve the optimum location within the hopper or feeder. The two sets of screws are approximately 2” (50mm) apart.

Hog Slat Inc. Newton Grove, NC USA August 2021 32 Grow-FlexTM Feed System Wiring: IMPORTANT Disconnect all electrical power before attempting installation of this (or any equipment), inspecting or servicing. Ground all electrical equipment in accordance with applicable codes. Do not assume equipment will automatically be grounded due to incidental metal-to-metal contact. ALL electrical wiring must be done by a qualified electrician in accordance with local and national electric codes. The HS529 Hopper Level Control is a single pole, double throw switch connected so that the circuit is normally closed (Motor Runs) when there is no feed present against the paddle. The circuit is open (Motor Stops) when there is feed against the paddle. The HS529 internal switch is rated for 20 amps (Approximately 1 HP). It can be directly connected in series to control a motor with less current requirement than 20 amps. If the motor current is greater than 20 amps, the Control Unit must be connected to a relay/contactor. Wiring for use with GrowerSELECT HS593 Control Unit

Hog Slat Inc. Newton Grove, NC USA August 2021 33 Grow-FlexTM Feed System Switch and Paddle Adjustment: The Hopper Control is set at the factory for Switch Sensitivity and Paddle Position for average feed weight and consistency. It is normal for the installer to make some fine tune adjustments based on actual feed weight and consistency. Important: The External Adjustment Nut is for paddle position only. Switch sensitivity can only be adjusted internally. Paddle Positioning 1. Place Control Unit in a vertical position with NO FEED in front of paddle. 2. Turn external nut CLOCKWISE until switch actuates (clicks). 3. Turn nut back COUNTER-CLOCKWISE until switch de-activates (clicks). 4. Turn nut TWO (2) additional full turns COUNTER-CLOCKWISE. Switch Sensitivity Adjustment: 1. Remove four (4) screws and lid from white control box on Control Unit. 2. Loosen the two (2) #6 slotted, hex washer head screws securing switch bracket inside white box. 3. Slide switch and bracket assembly accordingly: a. RIGHT to make unit Less Sensitive, requiring more feed to actuate b. LEFT to make More Sensitive, requiring less feed to actuate. 4. Re-tighten screws (do not over-tighten and strip) 5. Important: Paddle Position must be re-adjusted whenever switch sensitivity is adjusted.
