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 11 for ceiling installation.

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.

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.
SECTIONALDOORS
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. Mark, drill holes and install as follows, depending on your door’s construction:
Metal or light weight doors using a vertical angle iron brace between the door
panel support and the door bracket:
• Drill 3/16" fastening holes. Secure the door bracket using the two self threading screws.
(Figure1)
• Alternately, use two 5/16"-18x2" bolts, lock washers and nuts (not provided). (Figure2)
Metal, insulated or light weight factory reinforced doors:

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

Adjustments
Introduction
Without a properly installed safety reversal system, persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage door.
• Incorrect adjustment of garage door travel limits will interfere with proper operation of
safety reversal system.
• 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.

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 effect the
opening cycle.
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. Use an incandescent A19 light bulb (100 watt maximum).
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 39.
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 5feet 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.
48
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 for suggested maintenance.
• If any signs of damage are evident, contact a trained door systems technician for assistance.
• 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.

Test the opener safety features:
• Reconnect the opener to the door using the manual disconnect and open the door.
• 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.
