Preparation

Before You Connect with Your Smartphone

Monitor and control your garage door from anywhere using the myQ app. You will need:

•Wi-Fi enabled smartphone, tablet or laptop

•Broadband Internet Connection

•Wi-Fi signal in the garage (2.4 Ghz, 802.11b/g/n required)

•Password for your home network (router's main account, not guest network)

Test the Wi-Fi Signal Strength

Make sure your mobile device is connected to your Wi-Fi network. Hold your mobile device in the place where your garage door opener will be installed and check the Wi-Fi signal strength.

Check Signal Strength. If you see:

Wi-Fi signal is strong.

The garage door opener will connect to your Wi-Fi network.

Wi-Fi signal is weak.

The garage door opener may connect to your Wi-Fi network. If not, try one of the options below to improve the Wi-Fi signal:

No Wi-Fi signal.

The garage door opener will not be able to connect to your Wi-Fi network. Try one of the options below to improve the Wi-Fi signal:

• Move your router closer to the garage door opener to minimize interference from walls and other objects

• Buy a Wi-Fi range extender

For compatible router specifications and help, visit LiftMaster.com/customer-support.

See page 35 to connect the garage door opener to a mobile device.

•NEVER try to loosen, move oradjust garage door, doorsprings, cables, pulleys, brackets ortheirhardware, ALL of which are underEXTREME tension.

•Disable ALL locks and remove ALL ropes connected to garage doorBEFORE installation and operating garage dooropenerto avoid entanglement.

•DO NOT install on a one-piece doorif using devices orfeatures providing unattended close. Unattended devices and features are to be used ONLYwith sectional doors.

To prevent damage to garage doorand opener:

•ALWAYSdisable locks BEFORE installing and operating the opener.

•ONLYoperate garage dooropenerat 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 doorhalfway up. Release the door. If balanced, it should stay in place, supported entirely by its springs.

3.Raise and lowerthe doorto check forbinding orsticking. If yourdoorbinds, sticks, oris out of balance, call a trained door systems technician.

4.Check the seal on the bottom of the door. Any gap between the floorand the bottom of the doormust not exceed 1/4" (6 mm). Otherwise, the safety reversal system may not work properly.

5.The openershould be installed above the centerof the door. If there is a torsion spring orcenterbearing plate in the way of the headerbracket, it may be installed within 4 feet (1.2 m)to the left orright of the doorcenter. See page 11.

IMPORTANT INSTALLATION INSTRUCTIONS

To reduce the risk of SEVERE INJURY or DEATH:

1.READ AND FOLLOW ALL INSTALLATION WARNINGS AND INSTRUCTIONS.

2.Install garage door opener ONLY on properly balanced and lubricated garage door. An improperly balanced door may NOT reverse when required and could result in SEVERE INJURY or DEATH.

3.ALL repairs to cables, spring assemblies and other hardware MUST be made by a trained door systems technician BEFORE installing opener.

4.Disable ALL locks and remove ALL ropes connected to garage door BEFORE installing opener to avoid entanglement.

5.Where possible, install the door opener 7 feet (2.13 m) or more above the floor.

6.Mount the emergency release within reach, but at least 6 feet (1.83 m) above the floor and avoiding contact with vehicles to avoid accidental release.

7.NEVER connect garage door opener to power source until instructed to do so.

8.NEVER wear watches, rings or loose clothing while installing or servicing opener. They could be caught in garage door or opener mechanisms.

9. Install wall-mounted garage door control:

•within sight of the garage door.

•out of reach of small children at a minimum height of 5 feet (1.5 m)above floors, landings, steps orany otheradjacent walking surface.

•away from ALL moving parts of the door.

10.Place entrapment warning label on wall next to garage doorcontrol in a prominent location.

11.Place emergency release/safety reverse test label in plain view on inside of garage door.

12.Upon completion of installation, test safety reversal system. Door MUST reverse on contact with a 1-1/2" (3.8 cm)high object (ora 2x4 laid flat)on the floor.

13.DO NOT install on a one-piece doorif using devices orfeatures providing unattended close. Unattended devices and features are to be used ONLYwith sectional doors.

12

Installation

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.

•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 14 for ceiling installation.

HARDWARE

LAG SCREW 5/16"-9X1-5/8"

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.

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.
