DO NOT install header bracket over drywall. ● Concrete anchors MUST be used if mounting header bracket or 2x4 into masonry. ● NEVER try to loosen, move or adjust garage door, springs, cables, pulleys, brackets, or their hardware, ALL of which are under EXTREME tension. ● ALWAYS call a trained door systems technician if garage door binds, sticks, or is out of balance. An unbalanced garage door might NOT reverse when required. ● DO NOT enable the Timer-to-Close functionality if operating either one-piece or swinging garage doors. To be enabled ONLY when operating a sectional door. Close the door and mark the inside vertical centerline of the garage door. Extend the line onto the header wall above the door. You can fasten the header bracket within 4 feet (1.22 m) of the left or right of the door center only if a torsion spring or center bearing plate is in the way; or you can attach it to the ceiling when clearance is minimal. (It may be mounted on the wall upside down if necessary, to gain approximately 1/2" (1 cm). 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. Open your door to the highest point of travel as shown. Draw an intersecting horizontal line on the header wall 2" (5 cm) above the high point. This height will provide travel clearance for the top edge of the door. NOTE: If the total number of inches exceeds the height available in your garage, use the maximum height possible, or refer to page 12 for ceiling installation. 11 OPTIONAL Unfinished Ceiling CEILING MOUNT FOR Header Wall HEADER BRACKET 2x4 Vertical Centerline of Garage Door 2x4 Structural Supports Level (Optional) Header Wall 2" (5 cm) Track Highest Point of Travel Door Sectional door with curved track Installation 2 Install the Header Bracket You can attach the header bracket either to the wall above the garage door, or to the ceiling.

Trolley Release Arm 16 Installation 8 Install the Door Bracket Fiberglass, aluminum or lightweight steel garage doors WILL REQUIRE reinforcement BEFORE installation of door bracket. Contact the garage door manufacturer or installing dealer for opener reinforcement instructions or reinforcement kit. Failure to reinforce the top section as required according to the door manufacturer may void the door warranty. A horizontal and vertical reinforcement is needed for lightweight garage doors (fiberglass, aluminum, steel, doors with glass panel, etc.) (not provided). 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. Contact the garage door manufacturer or installing dealer for opener reinforcement instructions or reinforcement kit. NOTE: Many door reinforcement kits provide for direct attachment of the clevis pin and door arm. In this case you will not need the door bracket; proceed to the next step. SECTIONAL DOORS 1. Center the door bracket on the previously marked vertical centerline used for the header bracket installation. Note correct UP placement, as stamped inside the bracket. 2. Position the top edge of the bracket 2"-4" (5-10 cm) below the top edge of the door, OR directly below any structural support across the top of the door. 3.

Install the Protector System® Introduction Be sure power is NOT connected to the garage door opener BEFORE installing the safety reversing sensor. To prevent SERIOUS INJURY or DEATH from 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. IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSORS The safety reversing sensors must be connected and aligned correctly before the garage door opener will move in the down direction. The sending sensor (with an amber LED) transmits an invisible light beam to the receiving sensor (with a green LED). If an obstruction breaks the light beam while the door is closing, the door will stop and reverse to the full open position, and the garage door opener lights will flash 10 times. NOTE: For energy efficiency the garage door opener will enter sleep mode when the door is fully closed. The sleep mode shuts the garage door opener down until activated. The sleep mode is sequenced with the garage door opener lights; as the lights turns off, the sensor LEDs will turn off and whenever the garage door opener lights turn on, the sensor LEDs will light. The garage door opener will not go into the sleep mode until the garage door opener has completed 5 cycles upon power up. When installing the safety reversing sensors check the following: ● Sensors are installed inside the garage, one on either side of the door. ● Sensors are facing each other with the lenses aligned and the receiving sensor lens does not receive direct sunlight. ● Sensors are no more than 6 inches (15 cm) above the floor and the light beam is unobstructed. 22 Safety Reversing Sensor 6" (15 cm) max. above floor Invisible Light Beam Protection Area Invisible Light Beam Protection Area Safety Reversing Sensor 6" (15 cm) max. above floor Safety Reversing Sensor 6" (15 cm) max. above floor Safety Reversing Sensor 6" (15 cm) max. above floor

An improperly adjusted garage door and opener can exert deadly force when the door closes – which could lead to entrapment of children or adults and subsequent injury or death. Proper installation, operation, maintenance, and testing of the garage door and automatic opener are necessary to provide a safe, trouble-free system. Careless operation or allowing children to play with or use garage door opener controls are also dangerous situations that can lead to tragic results. A few simple precautions can protect your family and friends from potential harm. Please review the safety and maintenance tips in this guide carefully and keep it for reference. Check the operation of your garage door and opener to ensure they function in a safe and trouble-free manner. Be sure to read all Important Safety Information found in your garage door opener’s manual as it provides more details and safety considerations than can be supplied with this guide. Garage Door Openers are Not Toys Discuss garage door and opener safety with your children. Explain the danger of being trapped under the door. Stay away from a moving door. The wall-mounted push button should be out of reach of children, at least 5 feet from the nearest standing surface and away from all moving parts. Mount and use the button where you can clearly see the closing garage door.

Keep transmitters and remote controls out of reach of children. Do not let children play with or use transmitters orother remote control devices. Keep the door in sight until it completely closes when using the wall-mounted push button or transmitter. 47

Routine Maintenance Can Prevent Tragedies Make monthly inspection and testing of your garage door and opener system a part of your regular routine. Review your owner’s manual for both the door and door opener. If you don’t have the owner’s manuals, contact the manufacturer(s) and request a copy for your specific model(s). Look for the opener model number on the back of the power unit. WARNING – Springs are under high tension. Only qualified individuals should adjust them. Visually check the door and installation: ● Starting with the door in the closed position, use the manual disconnect on the opener to disconnect the door. ● Look for signs of wear or damage on hinges, rollers, springs, and door panels. ● These parts may require periodic lubrication. Check the owner’s manual forsuggested maintenance. ● If any signs of damage are evident, contact a trained door systems technician forassistance. ● Verify the photoeye height is no higher than 6" from the garage floor. Test the door for proper operation: ● Open and close the door manually using handles or suitable gripping points. ● The door should move freely and without difficulty. ● The door should balance and stay partially open 3–4 feet above the floor. ● If you detect any signs of improper operation, contact a trained door systems technician for assistance. 1 Test the opener safety features: ● Reconnect the opener to the door using the manual disconnect and open the door. 2 ● Place a 2x4 board flat in the path of the door (1) and try to close it (2). The door should stop when it comes in contact with the 2x4 and then reverse direction. ● Block the photoelectric sensor by waving an object in front of the sensor and attempt to close the door. The door should not close unless the wall-mounted push button is manually held during operation. ● If the opener does not perform as described, contact a trained door systems technician for assistance. 48
