1 Determine the Header Bracket Location

NOTE: If you are installing the garage door opener on a one-piece door, visit LiftMaster.com for installation instructions.

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 10 for ceiling installation.

To prevent possible SERIOUS INJURY or DEATH:

l 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.

l Concrete anchors MUST be used if mounting header bracket or 2x4 into

masonry.

l NEVER try to loosen, move or adjust garage door, springs, cables, pulleys,

brackets, or their hardware, ALL of which are under EXTREME tension.

l 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.

l 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.

Invisible Light Beam Protection Area

Safety Reversing Sensor 6" (15 cm) max. above ﬂoor

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:

l Correctly connect and align the safety reversing sensor. This required safety

device MUST NOT be disabled.

l 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 light bulb; as the light bulb 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:

l Sensors are installed inside the garage, one on either side of the door. l Sensors are facing each other with the lenses aligned and the receiving sensor

lens does not receive direct sunlight.

l Sensors are no more than 6 inches (15 cm) above the floor and the light beam is

unobstructed.

Introduction

Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door.

l Incorrect adjustment of garage door travel limits will interfere with proper

operation of safety reversal system.

l After ANY adjustments are made, the safety reversal system MUST be tested.

Door MUST reverse on contact with 1-1/2" (3.8 cm) high object (or 2x4 laid flat) on floor.

To prevent damage to vehicles, be sure fully open door provides adequate clearance.

Your garage door opener is designed with electronic controls to make setup and adjustments easy. The adjustments allow you to program where the door will stop in the open (UP) and close (DOWN)position. The electronic controls sense the amount of force required to open and close the door. The force is adjusted automatically when you program the travel.

NOTE: If anything interferes with the door’s upward travel it will stop. If anything interferes with the door’s downward travel, it will reverse.

PROGRAMMING BUTTONS

The programming buttons are located on the left side panel of the garage door opener and are used to program the travel. While programming, the UP and DOWN buttons can be used to move the door as needed.

To watch a short instructional video on programming your new garage door opener use your smartphone to read the QR Code below.
