Preparing your garage door WARNING Before you begin: • Disable locks. • Remove any ropes connected to garage door. • Complete the following test to make sure your garage door is balanced and is not sticking or binding: 1. Lift the door about halfway as shown. Release the door. If balanced, it should stay in place, supported entirely by its springs. 2. Raise and lower the door to see if there is any binding or sticking.
Planning Identify the type and height of your garage door. Survey your garage area to see if any of the conditions below apply to your installation. Additional materials may be required. You may find it helpful to refer back to this page and the accompanying illustrations as you proceed with the installation of your opener. FINISHED CEILING SECTIONAL DOOR INSTALLATION Support bracket & fastening hardware is required. See page 13.
Carton Inventory Your garage door opener is packaged in two cartons which contain the motor unit and all parts illustrated below. Accessories will depend on the model purchased. If anything is missing, carefully check the packing material. Parts may be stuck in the foam. Hardware for installation is also listed below.
WARNING CAUTION ASSEMBLY STEP 1 Attach the T-Rail to the Motor Unit To avoid SERIOUS damage to opener, ONLY use bolts mounted in top of motor unit. To avoid installation difficulties, do not run the garage door opener until instructed to do so. • Remove the two washered bolts mounted in top of motor unit. • Align T-rail and styrofoam over sprocket. Cut tape from T-rail, chain and styrofoam. • REMOVE STYROFOAM. • Insert both washered bolts through the T-rail into the motor unit. Tighten bolts securely.
WARNING ASSEMBLY STEP 3 Attach the Belt Cap Retainer To avoid possible SERIOUS INJURY to fingers from moving garage door opener: • ALWAYS keep hand clear of sprocket while operating opener. • Securely attach sprocket cover BEFORE operating. CAUTION • Position the belt cap retainer over the motor unit sprocket so the two holes in cap align with the two holes in mounting plate. Attach with #8x3/8" hex screws provided. You have now finished assembling your garage door opener.
INSTALLATION STEP 1 Determine the Header Bracket Location Finished Ceiling Vertical Centerline Header Wall 2x4 WARNING Structural Supports WARNING To prevent possible SERIOUS INJURY or DEATH: • Header bracket MUST be RIGIDLY fastened to structural support on header wall or ceiling, otherwise garage door might not reverse when required. DO NOT install header bracket over drywall. • Concrete anchors MUST be used if mounting header bracket or 2x4 into masonry.
ONE-PIECE DOOR WITHOUT TRACK 1. Close the door and mark the inside vertical centerline of your garage door. Extend the line onto the header wall above door, as shown. If headroom clearance is minimal, you can install the header bracket on the ceiling. See page 10. If you need to install the header bracket on a 2x4 (on wall or ceiling), use lag screws (not provided) to securely fasten the 2x4 to structural supports as shown. 2. Open your door to the highest point of travel as shown.
INSTALLATION STEP 2 Install the Header Bracket Wall Mounting Holes 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. Do not install the header bracket over drywall. If installing into masonry, use concrete anchors (not provided). CEILING MOUNT ONLY The nail hole is for positioning only. You must use lag screws to mount the header bracket.
INSTALLATION STEP 3 Attach the T-Rail to the Header Bracket • Position the opener on the garage floor below the header bracket. Use packing material as a protective base. NOTE: If the door spring is in the way you’ll need help. Have someone hold the opener securely on a temporary support to allow the rail to clear the spring. • Position the rail bracket against the header bracket. • Align the bracket holes and join with a clevis pin as shown. • Insert a ring fastener to secure.
WARNING CAUTION INSTALLATION STEP 4 Position the Opener To prevent damage to garage door, rest garage door opener rail on 2x4 placed on top section of door. Follow instructions which apply to your door type as illustrated. SECTIONAL DOOR OR ONE-PIECE DOOR WITH TRACK A 2x4 laid flat is convenient for setting an ideal doorto-rail distance. • Raise the opener onto a stepladder. You will need help at this point if the ladder is not tall enough.
WARNING 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 support. On finished ceilings (Figure 2), attach a sturdy metal bracket to structural supports before installing the opener. This bracket and fastening hardware are not provided. 1. Remove foam packaging. Measure the distance from each side of the motor unit to the structural support. 2.
WARNING WARNING INSTALLATION CAUTION STEP 6 WARNING Install the Door Control Locate door control within sight of the door at a minimum height of 5 feet where small children cannot reach, and away from moving parts of the door and door hardware. The installation surface must be smooth and flat. If installing into drywall (Figure 1), drill 5/32" holes and use anchors provided. For prewired installations (as in new home construction), it may be mounted to a single gang box (Figure 2).
INSTALLATION STEP 7 Install the Lights 100 Watt (Max) Standard Light Bulb • Press the release tabs on both sides of lens. Gently rotate lens back and downward until the lens hinge is in the fully open position. Do not remove the lens. • Install up to a 100 watt maximum light bulb in each socket. The lights will turn ON and remain lit for approximately 4-1/2 minutes when power is connected. Then the lights will turn OFF. • Reverse the procedure to close the lens.
INSTALLATION WARNING STEP 9 WARNING Electrical Requirements To prevent possible SERIOUS INJURY or DEATH from electrocution or fire: • Be sure power is not connected to the opener, and disconnect power to circuit BEFORE removing cover to establish permanent wiring connection. • Garage door installation and wiring MUST be in compliance with all local electrical and building codes. • NEVER use an extension cord, 2-wire adapter, or change plug in any way to make it fit outlet. Be sure the opener is grounded.
WARNING INSTALLATION STEP 10 Install The Protector System ® • Be sure power is not connected to the garage door opener BEFORE installing the safety reversing sensor. • To prevent SERIOUS INJURY or DEATH from a closing garage door: – Correctly connect and align the safety reversing sensor. This required safety device MUST NOT be disabled. – Install the safety reversing sensor so beam is NO HIGHER than 6" above garage floor.
INSTALLING THE BRACKETS Be sure power to the opener is disconnected. Install and align the brackets so the sensors will face each other across the garage door, with the beam no higher than 6" above the floor. They may be installed in one of three ways, as follows. Figure 1 DOOR TRACK MOUNT (RIGHT SIDE) Door Track Garage door track installation (preferred): • Slip the curved arms over the rounded edge of each door track, with the curved arms facing the door. Snap into place against the side of the track.
MOUNTING AND WIRING THE SAFETY SENSORS • Slide a 1/4"-20x1/2" carriage bolt head into the slot on each sensor. Use wing nuts to fasten sensors to brackets, with lenses pointing toward each other across the door. Be sure the lens is not obstructed by a bracket extension (Figure 4). • Finger tighten the wing nuts. • Run the wires from both sensors to the opener. Use insulated staples to secure wire to wall and ceiling. • Strip 7/16" of insulation from each set of wires.
WARNING CAUTION INSTALLATION STEP 11 Fasten the Door Bracket To prevent damage to garage door, reinforce inside of door with angle iron both vertically and horizontally. Follow instructions which apply to your door type as illustrated below or on the following page. A horizontal reinforcement brace should be long enough to be secured to two or three vertical supports. A vertical reinforcement brace should cover the height of the top panel. Figure 1 shows one piece of angle iron as the horizontal brace.
ONE-PIECE DOORS Please read and comply with the warnings and reinforcement instructions on the previous page. They apply to one-piece doors also. • Center the door bracket on the top of the door, in line with the header bracket as shown. Mark either the left and right, or the top and bottom holes. • Metal Doors: Drill 3/16" pilot holes and fasten the bracket with the 1/4"-14x5/8" self-threading screws provided.
