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. Depending on your requirements, there are several installation steps which may call for materials or hardware not included in the carton.
Planning (Continued) ONE-PIECE DOOR INSTALLATIONS • Generally, a one-piece door does not require reinforcement. If your door is lightweight, refer to the information relating to sectional doors in Installation Step 11. • Depending on your door’s construction, you may need additional mounting hardware for the door bracket (Step 11). ONE-PIECE DOOR WITHOUT TRACK FINISHED CEILING Support bracket & fastening hardware is required. See page 16.

Hardware Inventory Separate all hardware and group as shown below for the assembly and installation procedures.
WARNING CAUTION ASSEMBLY STEP 1 Assemble the Rail & Install the Trolley To prevent INJURY from pinching, keep hands and fingers away from the joints while assembling the rail. To avoid installation difficulties, do not run the garage door opener until instructed to do so. 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" (8.9 cm) away is close to the rail edge.
WARNING CAUTION ASSEMBLY STEP 2 Fasten the Rail to the Motor Unit To avoid SERIOUS damage to garage door opener, use ONLY those bolts/fasteners mounted in the top of the opener. • Insert a 1/4"-20x1-3/4 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. Do NOT overtighten. • Remove the two bolts from the top of the motor unit. • Place the “U” bracket, flat side down, on the motor unit and align the bracket holes with the bolt holes.
WARNING ASSEMBLY STEP 4 Install the Belt and Attach the Belt Cap Retainer 1. Pull the belt around the idler pulley and toward the trolley. The ribbed side must contact the pulley. 2. Hook the trolley connector into the retaining slot on the trolley as shown. 3. With the trolley against the screwdriver, dispense the remainder of the belt along the rail length toward the motor unit and around the sprocket. The sprocket teeth must engage the belt. 4.
ASSEMBLY STEP 5 Set the Tension • Insert a screwdriver tip into one of the nut ring slots and brace it firmly against the trolley. • Place a 7/16" open end wrench on the square end. Rotate the nut about 1/4 turn until the spring releases and snaps the nut ring against the trolley. This sets the spring to optimum belt tension. Nut Ring Slot Square End You have now finished assembling your garage door opener. Please read the following warnings before proceeding to the installation section.
INSTALLATION STEP 1 Determine the Header Bracket Location 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.
INSTALLATION STEP 2 Wall Mount Install the Header Bracket 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).
INSTALLATION STEP 3 Attach the Rail to the Header Bracket NOTE: (Optional) With some existing installations, 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. NOTE: If the door spring is in the way you’ll need help.
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 door-to-rail distance. • Remove foam packaging. • Raise the opener onto a stepladder. You will need help at this point if the ladder is not tall enough.
INSTALLATION STEP 5 Hang the Opener To avoid possible SERIOUS INJURY from a falling garage door opener, fasten it SECURELY to structural supports of the garage. Concrete anchors MUST be used if installing any brackets into masonry. Three representative installations are shown. Yours may be different. Hanging brackets should be angled (Figure 1) to provide rigid support. On finished ceilings (Figure 2 and Figure 3), attach a sturdy metal bracket to structural supports before installing the opener.
WARNING WARNING INSTALLATION CAUTION STEP 6 WARNING Install the Door Control To prevent possible SERIOUS INJURY or DEATH from electrocution: • Be sure power is not connected BEFORE installing door control. • Connect ONLY to 24 VOLT low voltage wires. To prevent possible SERIOUS INJURY or DEATH from a closing garage door: • Install door control within sight of garage door, out of reach of children at a minimum height of 5 feet (1.5 m), and away from ALL moving parts of door.
WARNING CAUTION INSTALLATION STEP 7 Install the Lights To prevent possible OVERHEATING of the endpanel or light socket: • DO NOT use short neck or specialty light bulbs. • DO NOT use halogen bulbs. Use ONLY incandescent. To prevent damage to the opener: • DO NOT use bulbs larger than 100W. • ONLY use A19 size bulbs. • 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.
INSTALLATION STEP 9 Electrical Requirements To avoid installation difficulties, do not run the opener at this time. To reduce the risk of electric shock, your garage door opener has a grounding type plug with a third grounding pin. This plug will only fit into a grounding type outlet. If the plug doesn't fit into the outlet you have, contact a qualified electrician to install the proper outlet. RIGHT WRONG If permanent wiring is required by your local code, refer to the following procedure.
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" (15 cm) above garage floor.

MOUNTING AND WIRING THE SAFETY REVERSING 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 5). • 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" (11 mm) of insulation from each set of wires.
WARNING CAUTION INSTALLATION STEP 11 Fasten the Door Bracket Fiberglass, aluminum or lightweight steel garage doors WILL REQUIRE reinforcement BEFORE installation of door bracket. Contact your door manufacturer for reinforcement kit. 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.
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.
INSTALLATION STEP 12 Connect Door Arm to Trolley Follow instructions which apply to your door type as illustrated below and on the following page. Trolley Stop Bolt SECTIONAL DOORS ONLY • Make sure garage door is fully closed. Pull the emergency release handle to disconnect the outer trolley from the inner trolley. Slide the outer trolley back (away from the pulley) about 8" (20 cm) as shown in Figures 1, 2 and 3.
ALL ONE-PIECE DOORS 1. Assemble the door arm, Figure 4: • Fasten the straight and curved door arm sections together to the longest possible length (with a 2 or 3 hole overlap). • With the door closed, connect the straight door arm section to the door bracket with the 5/16"x1-1/4" clevis pin. • Secure with a ring fastener. 2. Adjustment procedures, Figure 5: • On one-piece doors, before connecting the door arm to the trolley, the travel limits must be adjusted.
ADJUSTMENT STEP 1 Adjust the UP and DOWN Travel Limits Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door. • Incorrect adjustment of garage door travel limits will interfere with proper operation of safety reversal system. • If one control (force or travel limits) is adjusted, the other control may also need adjustment. • After ANY adjustments are made, the safety reversal system MUST be tested.
WARNING ADJUSTMENT STEP 2 Adjust the Force Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door. • Too much force on garage door will interfere with proper operation of safety reversal system. • NEVER increase force beyond minimum amount required to close garage door. • NEVER use force adjustments to compensate for a binding or sticking garage door.
WARNING ADJUSTMENT STEP 3 Test the Safety Reversal System Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door. • Safety reversal system MUST be tested every month. • If one control (force or travel limits) is adjusted, the other control may also need adjustment. • After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with 1-1/2" high (3.
