x 3. sleeve anchors (precast). NOTE: Spring pads must be securely anchored before proceeding. The pads must by flush with the jambs. Attach the spring support brackets to the pad(s) using the following fasteners: Pre-Cast: Secure each spring support bracket using (2) 1/2. x 3. sleeve anchors. This installation will require the 1/2. anchors to be secured to the building, then securing the brackets to the anchors as detailed in Fig. N Page 11. Steel: Secure each spring support bracket using (3) 5/16. x 1. self-drilling and tapping screws as detailed in Fig. N Page 11. Block Construction: Attach perforated angle 18. long to support bracket(s) using (2) 3/8. x 1-1/4. bolts and nuts. Chamfer angle to clear top section high arc. Secure support brackets and perforated angle to block using (4) 3/8. x 2-1/2. sleeve anchors as detailed in Fig. N Page 11. Secure the stationary cone(s) (dead end) to the spring support bracket(s) using 3/8. bolts and nuts. Keep spring warning tags clearly visible. NOTE: The coupler support brackets only require (2) fasteners. The spring support brackets require (2) fasteners in the lower slot and hole, then (1) fastener in the top slot. WARNING: Failure to use proper number of fasteners can result in sudden spring tension release, causing severe injury or death. NOTE: Each 3-3/4., 6. and Duplex spring is secured to a separate center support bracket. DO NOT attach two springs of this size to one support bracket. STEP 11: Feed the cable attached to the left hand bottom bracket up the vertical track, behind the roller shafts and secure to the left hand drum. Push the drum up against the end bearing bracket and secure to the shaft by tightening the set screws (solid shafts use 1/4. key(s) and set screws to secure drums). Rotate drum and shaft until cable is taut, then apply vice grips to shaft, with end resting against header. This will hold cable taut and on drum. There must be at least 1/2 wrap of cable on the drum. If not, contact Wayne-Dalton for proper length cables. Attach other cable to right hand drum. Push drum against end bearing bracket and rotate drum until cable is taut. Secure drum to shaft by tightening the set screws. Cable tension must be equal on both drums on single shaft applications. On split shaft applications, apply vice grips to both shafts and secure bolts in coupling after springs are fully wound. If top section is not installed, do so now, before winding springs. Make sure hardware is securely attached to all sections. Carefully following spring winding instructions detailed in Fig. M on Page 10, wind spring(s), using the appropriate 1/2., 5/8. or 3/4. diameter winding rods of sufficient length. STEP 6. Secure the end hinges, (one side only) center hinges, and strutting ( if applicable) as previously illustrated. Locate the Lock Section (usually the second section) and insert a roller into the end hinge. Stack this section into the opening by hooking the roller in the vertical track and lowering it onto the bottom section. Insert a roller into the appropriate end hinge and insert roller into vertical track on the opposite end. Secure end hinge to the section using the self-drilling and tapping screws. Align the section edges, flip up the upper hinge leafs and secure to the lock section using the self-drilling and tapping screws. Continue to hardware and stack the remaining sections in the proper sequence. Attach the top brackets to the upper corners, of the top section, using self drilling and tapping screws as shown in Fig. J. NOTE : Top section maybe installed now or may wait until the last step (installer preference) STEP 7. Adjust the vertical track from 1/2. spacing at the bottom section to 3/4. at the top section. Refer to page 3. Permanently secure each vertical to the jambs using the following fasteners: Steel Jambs: 5/16. x 1. self drilling and tapping screw. Wood Jambs: 5/16. x 1-5/8. lag screw. Precast or Block: 3/8. x 3. sleeve anchor. The left hand vertical track assembly indicates the standard fastener spacing (Fig. K page 7). STEP 8: Use chain or cable to temporarily suspend the rear of the horizontal tracks. Secure the horizontal reinforcing angle to the wall angle using (1) 3/8. x 3/4. truss bolt and nut, then secure the horizontal track to the splice plate or flagangle using (2) track bolts and hex flange nuts. STEP 9: Torsion spring assemblies can be of several configurations depending on door size and weight. Left or right hand spring(s) must be identified by the color of the winding cone. (Refer to Fig. L and pages 8-10) Assemble torsion spring system components to applicable configuration shown on pages 8-10. Ensure that spring warning tags are securely wired to all stationary spring cones. WARNING: Install support brackets to solid structural members only. Do not install over dry wall or paneling. NOTE: Use a chalk line or line level to ensure all support brackets are in line. Fig. N (2) 3/8. x 1. or 1-1/2. Bolts (2) 3/8. Nuts and Washers Sp...
