Check the Door

To prevent possible SERIOUSINJURYor DEATH:
l 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.
l NEVER try to loosen, move or adjust garage door, door springs, cables,
pulleys, brackets or their hardware, ALLof which are under EXTREME tension.
l Disable ALLlocks and remove ALLropes connected to garage door BEFORE
installation and operating garage door opener to avoid entanglement.
l DO NOT install on a one-piece door if using devices or features providing
unattended close. Unattended devices and features are to be used ONLY with sectional doors.
To prevent damage to garage door and opener:
l ALWAYS disable locks BEFORE installing and operating the opener. l ONLY operate garage door opener at 120V, 60Hz to avoid malfunction and
damage.
Before you begin:
1. Disable locks and remove any ropes connected to the garage door.
2. Lift the door halfway up. Release the door. If balanced, it should stay in place, supported entirely by its springs.
3. Raise and lower the door to check for binding or sticking. If your door binds, sticks, or is out of balance, call a trained door systems technician.
4. Check the seal on the bottom of the door. Any gap between the floor and the bottom of the door must not exceed 1/4" (6 mm). Otherwise, the safety reversal system may not work properly.
5. The opener should be installed above the center of the door. If there is a torsion spring or center bearing plate in the way of the header bracket, it may be installed within 4feet (1.2 m) to the left or right of the door center. See page 11.

1 Determine the Header Bracket Location

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.
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 14 for ceiling installation.

2 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).
OPTION A - WALL INSTALLATION
1. Center the bracket on the vertical centerline with the bottom edge of the bracket on the horizontal line as shown (with the arrow pointing toward the ceiling).
2. Mark the vertical set of bracket holes (do not use the holes designated for ceiling mount). Drill 3/16" pilot holes and fasten the bracket securely to a structural support with lag screws.
OPTION B - CEILING INSTALLATION
1. Extend the vertical centerline onto the ceiling as shown.
2. Center the bracket on the vertical mark, no more than 6" (15cm) from the wall. Make sure the arrow is pointing toward the wall. The bracket can be mounted flush against the ceiling when clearance is minimal.
3. Mark the side holes. Drill 3/16" pilot holes and fasten bracket securely to a structural support with the hardware provided.

3 Attach the Rail to the Header Bracket

1. Align the rail with the header bracket. Insert the clevis pin through the holes in the header bracket and rail. Secure with the ring fastener.
NOTE: Use the packing material as a protective base for the garage door opener.

4 Position the Garage Door Opener

To prevent damage to garage door, rest garage door opener rail on 2x4 placed on top section of door.
1. Remove the packing material and lift the garage door opener onto a ladder.
2. Fully open the door and place a 2x4 (laid flat) under the rail. A 2x4 is ideal for setting the distance between the rail and the door. If the ladder is not tall enough you will need help at this point. If the door hits the trolley when it is raised, pull the trolley release arm down to disconnect the inner and outer trolley. Slide the outer trolley toward the garage door opener. The trolley can remain disconnected until instructed.

5 Hang the Garage Door 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.
Hanging your garage door opener will vary depending on your garage. 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. Measure the distance from each side of the motor unit to the structural support.
2. Cut both pieces of the hanging bracket to required lengths.
3. Drill 3/16" pilot holes in the structural supports.
4. Attach one end of each bracket to a support with 5/16"-18 x 1-7/8" lag screws (not provided).
5. Fasten the opener to the hanging brackets with 5/16"-18 x 7/8" hex bolts, lock washers and nuts.
6. Check to make sure the rail is centered over the door (or in line with the header bracket if the bracket is not centered above the door).
7. Remove the 2x4. Operate the door manually. If the door hits the rail, raise the header bracket.
NOTE: DO NOT connect power to opener at this time.

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 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:
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.

The TTC feature automatically closes the door after a specified time period that can be adjusted using a TTC enabled door control (Models 881LMW or 880LMW). Prior to and during the door closing the garage door opener lights will flash and the garage door opener will beep.
myQ
myQ allows you to control your garage door opener from your mobile device or computer from anywhere. myQ technology uses a 900Mhz signal to provide two way communication between the garage door opener and myQ enabled accessories. The garage door opener has an internal gateway that allows the garage door opener to communicate directly with a home Wi-Fi®network and access your myQ account.
THE PROTECTOR SYSTEM®(SAFETY REVERSING SENSORS)
When properly connected and aligned, the safety reversing sensors will detect an obstruction in the path of the infrared beam. If an obstruction breaks the infrared beam while the door is closing, the door will stop and reverse to full open position, and the opener lights will flash 10 times. If the door is fully open, and the safety reversing sensors are not installed, or are misaligned, the door will not close from a remote control. However, you can close the door if you hold the button on the door control or keyless entry until the door is fully closed. The safety reversing sensors do not affect the opening cycle. For more information see page 22.
ENERGY CONSERVATION
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.
LIGHTS
The garage door opener light bulbs will turn on when the opener is initially plugged in; power is restored after interruption, or when the garage door opener is activated. The lights will turn off automatically after 4-1/2 minutes. An incandescent A19 light bulb (100 watt maximum) or for maximum energy efficiency a 26W (100W equivalent) compact fluorescent light (CFL) bulb may be used.
Light Feature
The garage door opener is equipped with an added feature; the lights will turn on when someone enters through the open garage door and the safety reversing sensor infrared beam is broken. For added control over the light bulbs on your garage door opener, see page 37.
AUTOMATIC GARAGE DOOR LOCK*
Garage door opener models featuring the Security Shield are compatible with the LiftMaster Automatic Garage Door Lock (Model 841LM). See Accessories, page43.
* If applicable.
USING YOUR GARAGE DOOR OPENER
The garage door opener can be activated through a wall-mounted door control, remote control, wireless keyless entry or myQ accessory. When the door is closed and the garage door opener is activated the door will open. If the door senses an obstruction or is interrupted while opening the door will stop. When the door is in any position other than closed and the garage door opener is activated the door will close. If the garage door opener senses an obstruction while closing, the door will reverse. If the obstruction interrupts the sensor beam the garage door opener lights will blink 10 times. However, you can close the door if you hold the button on the door control or keyless entry until the door is fully closed. The safety reversing sensors do not affect the opening cycle. The safety reversing sensor must be connected and aligned correctly before the garage door opener will move in the down direction.
BATTERY BACKUP*
The battery backup system allows access in and out of your garage, even when the power is out. When the garage door opener is operating on battery power, the garage door opener will run slower, the light will not function, the Battery Status LED will glow solid orange, and a beep will sound approximately every 2 seconds.
