Carton Inventory Your garage door opener is packaged in two cartons which contain parts illustrated below. Accessories will depend on model purchased, if anything is missing, carefully check the packing material. Parts may be "stuck" in the foam. Hardware for assembly and installation is shown on page 7.
Separate all hardware from the packages in the rail carton and the opener carton, as shown below, for the assembly and installation procedures.
Assembly Section: Pages 8 - 11 To avoid installation difficulties, do not run the garage door opener until instructed to do so. Assembly Step I Assemble the Rail & Install I the I Trolley The front rail has a cut out "window"at the door end (see illustration). The hole above this window is larger on the top of the rail than on the bottom. A smaller hole 3-1/2" away is close to the rail edge. The back rail has a similar hole close to the edge, about 4-3/4" from the far end.
Assembly Step 2 I I Fasten the Rail to the Opener • Insert a 1/4"-20xl -3/4 bolt into the cover protection bolt hole on the back end of the rail as shown. Tighten securely with a 1/4"-20 lock nut. To fasten rail, use only those screws mounted in the top of the opener. Any other screws will cause serious damage to the opener. • Remove the two screws from the top of the opener. • Place the U bracket, flat side down, on the opener and align the bracket holes with the screw holes.
Assembly Step 4 Install the Chain/Cable and Attach the Sprocket Cover 1. Pull the cable around the idler pulley and toward the trolley. 2. Connect the cable loop to the retaining slot on the trolley, as shown: • From below, push pins of master link bar up through cable loop and trolley slot. Dispensing Carton • Push master link cap over pins and past pin notches. Leave Chainand Cable Inside D_spensing Carton to PreventKinking.
Assembly Step 5 Tighten the Chain I • Spin the inner nut and lock washer down the threaded shaft, away from the trolley. Figure I o=_ Lo_ Tro,.y Nut Washer • To tighten the chain, turn outer nut in the direction shown (Figure 1). ToT_.,_n Outer Nut.--_ I ! Shaft / • When the chain is approximately 1/2" above the base of the rail at its midpoint, re-tighten the inner nut to secure the adjustment. Sprocket noise can result if chain is too loose.
Installation Section: Pages 12 - 27 Installation Step I Determine Header Bracket Location If the header bracket Is not rigidly fastened to a structural support on the header wall or ceiling, the safety reverse system may not work properly (see page 30). The door might not reverse when required, and could cause serious injury or death. Installation procedures vary according to garage door types. Follow the instructions which apply to your door.
Read the Safety instructions on page 12. They also apply to doors without tracks. Header Wall Vertical Centerflne 2x4 • Close the door and mark the inside vertical centerline of your garage door. Extend the line onto the header wall above door. If headroom clearance is minimal, you can install the header bracket on the ceiling. See page 14.
Install the Header Bracket Installation Step 2 You can attach the header bracket either to the wall above the garage door, or to the ceiling. Follow the instructions which will work best for your particular requirements. I Wall Header Bracket Installation • Mark the vertical set of bracket holes. Drill 3/16" pilot holes and fasten the bracket securely to a structural support with the hardware provided.
Attach the Rail to the Header Installation Step 3 Bracket I NOTE: (Optional) With an existing Craftsman installation, you may re-use the old header bracket with the two plastic spacers included in the hardware bag. Place the spacers inside the bracket on each side of the rail, as illustrated. • Position the opener on the garage floor below the header bracket. Use packing material as a protective base. If the door spring is in the way you'll need help.
Installation Step 4 Position the Opener Follow instructions type as illustrated. which apply to your door A 2x4 laid flat is convenient for setting an ideal door-to-T-rail distance. Outer Trolley Inner Trolley • Raise the opener onto a stepladder as shown, You will need help at this point if the ladder is not tall enough. • Open the door all the way and place a 2x4 laid flat on the top section beneath the rail.
I Installation Step 5 Hang the Opener Two representative installations are shown. Yours may be different. Hanging brackets should be angled, Figure 1, to provide rigid suppod. On finished ceilings, Figure 2, attach a sturdy metal bracket to structural supports before installing the opener. The bracket and fastening hardware are not provided. See accessory page 38. 1. Measure the distance from each side of the opener to the structural support. Figure I Supports 2.
I Installation Step 6 Install the Door Control Locate the door control within sight of the door at a minimum height of 5 feet where small children cannot reach, and away from all moving parts of the door and door hardware. The door control is typically attached directly to the wall. If installing into drywall, drill 5/32" holes and use the anchors provided. For pre-wired installations (as in new home construction), Console models may be mounted to a standard single gang box (Figure 2). 1.
6. Attach the User Safety Instruction label to the wall near the door control, and the Maintenance Instruction label in a prominent location on the inside of the garage door. Do NOT connect the power and operate the openerat this time. The trolley will travel to the full open position but will not return to the close position until the sensor beam is connected and properly aligned. Page 32 explains how to use the door control. See Safety Reversing beginning on page 21.
Installation Electrical Step 9 Requirements I I To prevent electrocution or fire, installation and wiring must be in compliance with local electrical and building codes. To reduce the risk of electric shook, your garage door opener has a grounding type plug with a third grounding pin. This plug will onlyfit into a grounding type outlet. Do NOTuse an extension cord, 2-wire adapter, or change the plug in any way to make it fit your outlet.
The Safety Reversing System IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSOR The safety reversing sensor must be connected and aligned correctly before the garage door opener will move in the down direction. This is a required safety device and cannot be disabled. Without a properly working safety reversing sensor, persons (particularly children) could be injured or killed by a closing garage door.
