Preparing your garage door Before you begin: To prevent possible SERIOUS INJURY or DEATH: • ALWAYS call a trained door systems technician if garage door binds, sticks, or is out of balance. An unbalanced garage door may NOT reverse when required. • NEVER try to loosen, move or adjust garage door, door springs, cables, pulleys, brackets or their hardware, ALL of which are under EXTREME tension.
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. SECTIONAL DOOR INSTALLATION FINISHED CEILING Support bracket & fastening hardware is required. See page 15.
Carton Inventory If anything is missing, carefully check the packing material. Parts may be stuck in the foam. Hardware for installation is also listed below. 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.

INSTALLATION STEP 3 Attach the 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.
INSTALLATION STEP 4 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.
INSTALLING THE BRACKETS Figure 1 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" (15 cm) above the floor. They may be installed in one of three ways, as follows: DOOR TRACK MOUNT (RIGHT SIDE) Door Track Lip Indicator Light Garage door track installation (preferred): • Slip the curved arms over the rounded edge of each door track, with the curved arms facing the door.
MOUNTING AND WIRING THE SAFETY SENSORS Figure 5 • 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). Wing Nut • Finger tighten the wing nuts. Carriage Bolt 1/4"-20x1/2" Recommended Wire Routing Lens 1. Using insulated staples, run the wires from both sensors to the rail at the door header (Figure 6).

INSTALLATION STEP 6 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.
INSTALLATION STEP 7 Install the Door Control To prevent possible SERIOUS INJURY or DEATH from Locate door control within sight of the door at a minimum electrocution: height of 5 feet (1.5 m) where small children cannot reach, and away from moving parts of the door and door • Be sure power is NOT connected BEFORE installing hardware. The installation surface must be smooth and flat. door control. If installing into drywall (Figure 1), drill 5/32" holes and use • Connect ONLY to 24 VOLT low voltage wires.

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. HARDWARE SHOWN ACTUAL SIZE • 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.

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.
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.
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.
