3. EQUIPMENT OVERVIEW General Design Criteria NOTE : Dryer design is based on load factors - if you wish to add more sections to your dryer in the future, please let NECO know when you place your order so it will be designed to fit to your expanding needs. TIER INFORMATION : A tier is a set of parts that make up ONE layer of the dryer (also called body section). The top four tiers on all dryers are made up of 18 gauge material. The tiers below the 18 gauge tiers will be made of heavier materials - based on the required strength of that dryer configuration. BODY SECTION INFORMATION : A dryer section may be made up of 3, 4, 5 or 6 tiers, a blower, and a burner assembled together. The lowest body section is attached to the dryer frame and includes the entrance door. DRYER PART # : Example -- 24 20 3 0 3 0 P - 498 First two digits = 12, 16, 24 or 32 (Length) Second two digits = # of Tiers Fifth digit = Elec 2 = 230V Single Phase 3 = 230V Three Phase 4 = 460V Three Phase 6 = 380V 50 Hz Sixth digit = Fuel 0 = LP 1 = Natural Gas Seventh digit = Fill System 2 = Open Top with Level Auger 3 = Gravity Fill 4 = Roof with Level Auger Eighth digit = Cooling 0 = Cooling, 1 = AH Ninth digit = Control P = PLC Remaining digits = Serial # (# of unit built) DRYER RATING LABEL : STANDARD LENGTHS : 12 (144 ), 16 (192 ), 24 (288 ), 32 (384 ) TOTAL TIER LEVELS PER LENGTH : 12 -- min 4 tiers / max 6 tiers 16 -- min 5 tiers / max 6 tiers 24 -- min 6 tiers / max 24 tiers 32 -- mins 12 tiers / max 24 tiers DRYER MODEL # : Example: D 12 40 The two digits after D are the dryer length. This example would be a 12 foot long dryer. The remaining digits times 10 would be the approximate bushel capacity for corn. This example would be (10 x 40) or 400 bushels. A model #D32500 would be a dryer that is 32 feet long and have approximately 5,000 bushel capacity. NOTE: See APPENDIX - Standard Model Specifications for detailed bushel capacity values. 14

4. SITE PREP Concrete Work - Overview WARNING NECO recommends always hiring an expert for proper advise, accurate paperwork, and safe procedures to complete this task in conformance with local codes. WARNING The actual foundation specifications and concrete pad specifications must be determined from local data. Anchors that are sufficient for local wind loading must be installed. Consult a Civil Engineer. ATTENTION The weight of grain in a full NECO dryer will range from 16 tons to over 200 tons. It is necessary to support the frame of the dryer with properly designed and sized footings. NECO recommends having a concrete pad under the dryer to allow for easy clean-up. The dryer must be anchored and also secured against wind loading. Consult a civil engineer who s experienced with soil AND wind conditions in your area. Work with your millwright or installer & consult NECO if needed. 19

Identify Groups of Parts NOTE: All dryers require some assembly - the following information is included to help organize that overall task: The level of assembly required depends on many factors concerning the dryer model and optional equipment. Gather, identify, and separate all parts and hardware (See hardware chart below). Study this manual and look closely at the equipment overview section to become familiar with the various parts. Ultimately, for smooth assembly the parts should be organized into groups. Assembly Hardware Key ASSEMBLY HARDWARE KEY KEY ITEM DESCRIPTION HB HEX BOLT CB CARRIAGE BOLT FW FLAT WASHER LW LOCK WASHER HN HEX NUT WL FLANGED WIZ-LOCK NUT WN WING NUT NOTE: Unless otherwise specified, standard assembly hardware should be zinc plated and Grade 5. Tighten all connections firmly. 21

Set Up Fuel Supply Propane (LP) Fuel Source Contact your gas supplier regarding the location of fuel tanks and the safe storage, transport and handling of fuel. The LP storage tank must be located at least 25 ft [8 meters] from any structures. Local codes may require more distance. When propane is the fuel source the tank should be equipped with both a vapor tap and a liquid tap. The liquid tap should have a rapid flow shutoff valve. This valve will stop the flow of propane if a fuel line breaks. Help prevent oil sediment from entering the fuel system by propping one end of the propane tank higher than the other end, as shown in Figure 4B. WARNING NECO suggests hiring a professional to plan, setup, and connect the chosen fuel supply - Liquid Propane or Natural Gas. Either type MUST include an emergency shut-off valve. If using a converted Anhydrous Ammonia Tank -- Fuel train components can be damaged by anhydrous ammonia. If a tank that has contained anhydrous ammonia is going to be used for LP gas fuel make sure that the tank is completely purged of the anhydrous ammonia. Ask your LP gas supplier how to purge your tank. NOTE: Fuel train components damaged by anhydrous ammonia are not covered under warranty. Oil entering the dryer fuel system will VOID the warranty on fuel train components - see Figure 4B. Vapor Valve Liquid Valve Tank Tee Liquid Oil To Dryer Figure 4B - LP Fuel System Setup 22

Sizing the LP Supply Line NOTE: Size the line for maximum capacity of your dryer system, while taking into consideration any future plans to upgrade. The supply regulator set should be located near the dryer to reduce the supply line length. Refer to Table 4C1 to determine the MAXIMUM burner output per dryer model. Then refer to Table 4C2 to choose a slightly greater flow rate for the current (or future) flow requirements. Based on that flow requirement, which includes the 1 psi pressure drop, see which choice of line material & length best suit the system requirements. TABLE 4C1 MAX BURNER FLOW MODEL # MAX OUTPUT (BTU/HR) D1240 6,000 D1250 6,000 D1260 6,000 D1670 6,000 D1680 6,000 D1690 6,000 D16106 12,000 D16120 12,000 D16140 12,000 D16160 18,000 D24108 12,000 D24150 12,000 D24180 15,000 D24210 18,000 D24240 21,000 D24260 24,000 D24330 30,000 D24380 36,000 D32260 22,500 D32340 30,000 D32440 37,500 D32500 45,000 Table 4C2 - LP FUEL INLET LINE SIZE LINE LINE LENGTH IN FEET (PROVIDES 1 PSI PRESSURE DROP) FLOW COPPER TUBING RATE TYPE K SCHEDULE 80 PIPE BTU / 3 /8 1 /2 5 /8 HR OD OD OD 1/4 3/8 1/2 3/4 1 1¼ 5,490 9 36 157 20 92 331 7,320 20 83 11 51 187 735 9,150 13 56 7 33 119 470 12,810 29 15 61 240 813 16,470 17 37 145 491 18,300 14 30 118 399 25,620 15 60 205 27,450 13 52 180 785 31,110 40 150 700 34,770 30 125 600 38,430 25 95 500 42,090 20 80 400 45,750 15 70 300 EXAMPLE: Dryer model #D24210 requires 18,000 BTU/HR in Table 4C1. Proper choice for flow per Table 4C2 would be the 18,300 flow value and this would give four possible choices of material / length combinations - one choice for copper tubing & three choices for SCHD 80 pipe. Natural Gas (NG) Fuel Source Refer to APPENDIX - NECO Grain Dryer Specifications for maximum heat capacity ouptut and ensure that the pressure supplied to the fuel train inlet is 15 to 20 psi. The natural gas inlet line fitting for all NECO Dryers is 2. The supply regulator set should be located near the dryer to reduce the supply line length. Final Check of Fuel System Verify that all joints are tight and that ALL shutoff valves work correctly. 23

Set Up Electrical Supply WARNING NOTE The Dryer Rating Label on the control panel lists the full-load amps required for the dryer and the input voltage. Refer to Table 4D for service amp information on various size dryers - be sure to add amperage requirements for any additional auxillary equipment. The customer is responsible for providing materials and labor to connect the control to the power source, including a properly sized and placed fused disconnect box. The elelctrical power supply will have to meet service amp requirements. Copper wire of the appropriate size, based on the required amps and distance, must be run between the main disconnect switch and the distribution block located in the dryer control panel. NECO recommends hiring an expert for proper advise, accurate paperwork, and safe procedures to complete electrical work in conformance with local codes.

6. INSTALLATION Position Lower Dryer at Location Position the lower dryer section at the final location. BE SURE to support the lower section using a crane or setting it on temporary blocks, etc.. Anchor Lower To Pad / Foundation Most dryer system utilize a NECO support leg option. Some dryer systems utilize both concrete piers and either the NECO legs or customer supplied legs. No matter the method, double-check and verify proper assembly - make sure system is secure. Check & Verify ALL anchor attachment systems before installing optional leg kit or the addition of any upper dryer sections. DETERMINE NEXT STEP -- If the dryer is configured for a NECO support leg system, proceed to the following section. If other means are being used, after the lower section achor system is completed and verified continue with Stack and Secure s. 49

Install NECO Leg Kit (OPTIONAL) NOTE: Skip this section if the dryer system does not utilize the optional NECO lifting legs. OVERVIEW The optional lifting leg system is based on requirements that vary with the size and capacity of the dryer. Leg kits are available in 24, 48, or 60 lengths. Most dryer systems with legs are set atop a concrete slab. Some do not have a slab, but have individual foundation piers for support and anchoring. The dryer should also be secured in a secondary manner (guy wires, for example). This is especially true for taller dryers, which have greater surface area exposed to the wind. Refer to Figure 6B and the descriptions on the following page to identify the leg styles and locations: WARNING Be sure to support the dryer s lower section assembly by hanging from a crane or sitting on blocks prior to installing ANY lifting legs.

Stack & Secure s WARNING Do NOT stack any additional sections on top of the bottom section unless it is secured to the foundation. ATTENTION -- The following stacking information is applicable for: Upper dryer sections - made up of 3-6 tier levels Top-most filling dryer section - made up of 1-2 tier levels and the topside filling system. NOTE: All styles of fill systems, including catwalk and / or safety cage, should be completely assembled on the ground and then lifted into position and secured. OVERVIEW Refer to APPENDIX - Dryer Layout Configuratioins for specifics on sections and section stacking order. Depending on the dryer model configuration, certain parts are installed at the factory and certain parts require installation as the sections are stacked. STACKING ORDER - If your dryer has multiple sections, make sure you stack the sections in the proper order. The dryer section with the cord set labeled 1 is the longest cord and would be the upper-most section located the furthest away from the control panel. Position the rest likewise - #2 cord set would be the next dryer section toward the bottom and so on. LP FUELED DRYERS: Be carefull of the LP vaporizer coils when stacking sections - they stick up slightly and can be damaged!!! PLATFORM SUPPORT COLUMNS: These are shipped wired to the platforms and should be mounted at the bottom to the Platform Support Angles prior to adding the next dryer section. LADDER SECTIONS: If ladder section lengths are level with the top tier of a dryer section, they are factory mounted. If they are not level with the shipped top tier, the ladder section for that section is wired to the platform floor - see Ladder Installation section for details.

Optional Removal of Platform Braces / Lifting Lugs Refer to Figure 6S: NOTE: The following items can be removed AFTER the dryer section has been stacked and secured. The Platform Shipping Braces can either be left in place or removed. The Lifting Lugs can either be left in place or removed. Replace all hardware Lifting Lugs Platform Braces Figure 6S- Platform Braces & Lifting Lugs can be removed or left in place Attach Ladder s OVERVIEW Ladder location depends on model type - single blower units have the ladder system mounted at the rear of dryer, to the LEFT of the plenum door. Dryers with multiple platforms have the ladder system mounted at the front of dryer, going up through the platform floors, on the opposite side of transition fuel train. If the ladder section matches the dryer section (4 tier section would match an 8 ladder section) the installation is completed at the factory. See APPENDIX - Dryer Layouts for specifics. The 10 (#040370) & 8 (#040369) ladder sections include two ladder brackets with each section supplied. The 4 (#044117) section includes one ladder bracket and is used only as the top-most section in the ladder system when required. It will always have to be installed. The top-most section of ladder (10, 8, or 4 ) attaches to the #088083 Ladder Connection Plates of the Safety Cage system using the #088028 ladder clips and 3/8 hardware. If the ladder section for a dryer section would be above the upper-most tier level for shipping, that ladder section is NOT factory mounted - it is shipped wired to that dryer section s platform. On most domestic systems, the brackets have been factory mounted when possible. It is suggested to either add each ladder section as the dryer sections are installed upward or to wait until all dryer sections and topside filling section have been installed. 60

Refer to Figure 6T: NOTE: For dryers with a roof and catwalk system, the 6 dimension from the edge of tier to the #080022 ladder bracket edge should be held closely or the #080083 ladder attachment brackets will not match up correctly. Note how the ladder bracket is positioned against the lip of a tier sdection - this provides alignment and additional stability. Drill 3/8" (10mm) Holes 6" (152mm) Figure 6T - Transfer drill holes to mount Ladder Brackets 61

Install Topside Filling WARNING Be sure to utilize spreader bars or similalr means to properly lift the unit. Main lift component should be vertical - do not use sharp angles on strapping!! Refer to Figure 6W: NOTE: Assembly of the topside filling section, attached to the topmost tier section, should have been done at ground level. Ensure the topside system is completed to this level before proceeding further. Make sure the #7714349 lifting lug top plates were removed for the section being stacked upon. Lift the completed topside filling section as one completed unit - use guide lines to assist in positioning. Figure 6W - Lift assembled topside filling section Refer to Figure 6X: NOTE: Be sure the safety cage #080083 ladder attachment brackets or final lader section line up correctly with the lower existing ladder sections upon final positining. Install into final position and secure Reference Figures 6J thru 6V and complete all that are necessary to secure the section. NOTE: In most cases, the top-most ladder section is a 4 section and already attached to the safety cage attachment brackets - use ladder clips to secure the two ladder sections together. For some models, the final ladder section may be 8 or 10 and need to be installed to the safety cage ladder attachment brackets. Figure 6X - Install into final position and secure #088028 ATTACHMENT BRACKET Refer to Figure 6Y: Using 3/8 hardware, finish connection of ladder system to the cage ladder connection brackets. #088028 LADDER CLIP 63 Figure 6Y - Finish ladder connection
