Check the Door
To prevent possible SERIOUSINJURYor 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, ALLof which are under EXTREME tension.
l Disable ALLlocks and remove ALLropes 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, 60Hz 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 4feet (1.2 m) to the left or right of the door
center. See page 13.

1 Determine the Header Bracket Location
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.
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.

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" (15cm) 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.

or light socket. DO NOT use LED bulbs as they may reduce the range or performance of your remote
control(s).
3. Rotate the lens up to close.
7 Attach the Emergency Release Rope and Handle
To prevent possible SERIOUS INJURY or DEATH from a falling garage door:
l If possible, use emergency release handle to disengage trolley ONLY when garage door is
CLOSED. Weak or broken springs or unbalanced door could result in an open door
falling rapidly and/or unexpectedly.
l NEVER use emergency release handle unless garage doorway is clear of persons and
obstructions.
l NEVER use handle to pull door open or closed. If rope knot becomes untied, you could
fall.
1. Insert one end of the emergency release rope through the handle. Make sure that “NOTICE” is
right side up. Secure with an overhand knot at least 1" (2.5 cm) from the end of the rope to
prevent slipping.
2. Insert the other end of the emergency release rope through the hole in the trolley release arm.
Mount the emergency release within reach, but at least 6 feet (1.83m) above floor, avoiding
contact with vehicles to prevent accidental release and secure with an overhand knot.
NOTE: If it is necessary to cut the emergency release rope, seal the cut end with a match or lighter to
prevent unraveling. Ensure the emergency release rope and handle are above the top of all vehicles to

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" (15 cm) above the floor and the light beam is unobstructed.

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.
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.

Automatic Garage Door Opener Safety & Maintenance Guide
Garage Door Opener Safety – An Automatic Decision
A garage door is the largest moving object in the home. 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 or
other remote control devices.
Keep the door in sight until it completely closes when using
the wall-mounted push button or transmitter.

Routine Maintenance Can Prevent Tragedies
1
2
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:
l Starting with the door in the closed position, use the manual disconnect on the opener to disconnect the door.
l Look for signs of wear or damage on hinges, rollers, springs, and door panels.
l These parts may require periodic lubrication. Check the owner’s manual for suggested maintenance.
l If any signs of damage are evident, contact a trained door systems technician for assistance.
l Verify the photoeye height is no higher than 6" from the garage floor.
Test the door for proper operation:
l Open and close the door manually using handles or suitable gripping points.
l The door should move freely and without difficulty.
l The door should balance and stay partially open 3–4 feet above the floor.
l If you detect any signs of improper operation, contact a trained door systems technician for assistance.
Test the opener safety features:
l Reconnect the opener to the door using the manual disconnect and open the door.
l 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.
l 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.
l If the opener does not perform as described, contact a trained door systems technician for assistance.
