• To avoid SERIOUS PERSONAL INJURY or DEATH from electrocution, disconnect ALL electric power BEFORE performing ANY service or maintenance.
• 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

STEP 1 Determine the header bracket location

Installation procedures vary according to garage door types. Follow the instructions which apply to your 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 (see page 13) 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 2×4 (on wall or ceiling), use lag screws (not provided) to securely fasten the 2×4 to structural supports as shown here and on page 13.
• 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:
  •  2″ (5 cm) above the high point for sectional door and one-piece door with track.
  •  8″ (20 cm) above the high point for one-piece door without track.

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 13 for ceiling installation.

STEP 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 dry wall. If installing into masonry, use concrete anchors (not provided).

WALL INSTALLATION

OPTION A WALL INSTALLATION

• 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).
• Mark the vertical set of bracket holes. Drill 3/16″ pilot holes and fasten the bracket securely to a structural support with the hardware provided.

OPTION B CEILING INSTALLATION

• Extend the vertical centerline onto the ceiling as shown.
• Center the bracket on the vertical mark, no more than 6″ (15 cm) from the wall. Make sure the arrow is pointing away from the wall. The bracket can be mounted flush against the ceiling when clearance is minimal.
• Mark the side holes. Drill 3/16″ pilot holes and fasten bracket securely to a structural support with the hardware provided.

CEILING INSTALLATION

STEP 3 Attach the rail to the header bracket

• Position the opener on the garage floor below the header bracket. Use packing material as a protective base.
• Position the rail bracket against the header bracket.
• Align the bracket holes and join with a clevis pin as shown.
• Insert a ring fastener to secure.

NOTE: If the door spring is in the way, you will need help. Have someone hold the opener securely on a temporary support to allow the rail to clear the spring.

STEP 4 Position the garage door opener

• Remove the packing material and lift the garage door opener onto a ladder.
• Fully open the door and place a 2×4 (laid flat) under the rail. For one-piece doors without tracks, lay the 2×4 on it’s side.

NOTE: A 2×4 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.

STEP 5 Hang the garage door opener

Hanging the garage door opener will vary depending on your garage. Below are three example installations. Your installation may be different. For ALL installations the garage door opener MUST be connected to structural supports. The instructions illustrate one of the examples below.

• On finished ceilings, use the lag screws to attach a support bracket (not provided) to the structural supports before installing the garage door opener.
• Make sure the garage door opener is aligned with the header bracket. Measure the distance from each side of the garage door opener to the support bracket.
• Cut both pieces of the hanging bracket to required lengths.
• Attach the end of each hanging bracket to the support bracket with appropriate hardware (not provided).
• Attach the garage door opener to the hanging brackets with the hex bolts, lock washers, and nuts.
• Remove the 2×4 and manually close the door. If the door hits the rail, raise the header bracket

STEP 6 Install the light bulbs

• Pull on the top sides of the light lens and rotate the light lens down.
• Insert an A19 incandescent (100W maximum) or compact fluorescent (26W, 100W equivalent) light bulb into the light socket.

NOTE: Do not use halogen, short neck, or specialty light bulbs as these may overheat the end panel or light socket. Do not use LED bulbs as they may reduce the range or performance of your remote controls.

STEP 7 Attach the emergency release rope and handle

• 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.
• 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 (1.83 m) above floor, avoiding contact with vehicles to prevent accidental release and secure with a 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 avoid entanglement.

STEP 8 Install the door bracket

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.

OPTION A SECTIONAL DOORS

• 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.
• 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.
• Mark, drill holes and install as follows, depending on your door’s construction.

INTRODUCTION

Install door control within sight of garage door, out of reach of small children at a minimum height of 5 feet (1.5 m) above floors, landings, steps or any other adjacent walking surface, and away from ALL moving parts of door. For gang box installations it is not necessary to drill holes or install the drywall anchors. Use the existing holes in the gang box.

NOTE : Your product may look different than the illustrations

PUSH BUTTON DOOR CONTROL

• Strip 1/4 inch (6 mm) of insulation from one end of the wire and separate the wires.
• Connect one wire to each of the two screws on the back of the door control. The wires can be connected to either screw.
• Mount the door control with the hardware provided

MULTI-FUNCTION DOOR CONTROL

• Strip 7/16 inch (11 mm) of insulation from one end of the wire and separate the wires.
• Connect one wire to each of the two screws on the back of the door control. The wires can be connected to either screw. If your garage is pre-wired for the door control choose any two wires to connect, note which wires are used so the correct wires are connected to the garage door opener in a later step.
• Mark the location of the bottom mounting hole and drill a 5/32 inch hole.
• Install the bottom screw, allowing 1/8 inch (3 mm) to protrude from the wall.
• Position the bottom hole of the door control over the screw and slide down into place.
• Lift the push bar up and mark the top hole.
• Remove the door control from the wall and drill a 5/32 inch hole for the top screw.
• Position the bottom hole of the door control over the screw and slide down into place. Attach the top screw.

STEP 11 Wire the door control to the garage door opener

• Run the white and red/white wire from the door control to the garage door opener. Attach the wire to the wall and ceiling with the staple (not applicable for gang box or pre-wired installations). Do not pierce the wire with the staple as this may cause a short or an open circuit.
• Strip 7/16 inch (11 mm) of insulation from the end of the wire near the garage door opener.
• Connect the wire to the red and white terminals on the garage door opener. If your garage is pre-wired make sure you use the same wires that are connected to the door control. To insert or release wires from the terminal, push in the tab with screw driver tip.

STEP 12 Attach the warning labels

• Attach the entrapment warning label on the wall near the door control with tacks or staples.
• Attach the manual release/safety reverse test label in a visible location on the inside of the garage door.

STEP 13 Install the Protector System

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:

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

The safety reversing sensors can be attached to the door track, the wall, or the floor. The sensors should be no more than 6 inches (15 cm) above the floor. If the door track will not support the sensor bracket a wall installation is recommended. Choose one of the following installations.

OPTION A DOOR TRACK INSTALLATION

• Slide the curved arms of the sensor bracket around the edge of the door track. Snap into place so that the sensor bracket is flush against the track.
• Slide the carriage bolt into the slot on each sensor.
• Insert the bolt through the hole in the sensor bracket and attach with the wing nut. The lenses on both sensors should point toward each other. Make sure the lens is not obstructed by the sensor bracket.

STEP 13 Install the Protector System® (continued)

OPTION B WALL INSTALLATION

• If additional clearance is needed an extension bracket (not provided) or wood blocks can be used.
• Make sure each bracket has the same amount of clearance so they will align correctly.
• Position the sensor bracket against the wall with the curved arms facing the door. Make sure there is enough clearance for the beam to be unobstructed. Mark holes.
• Drill 3/16 inch pilot holes for each sensor bracket and attach the sensor brackets to the wall using lag screws (not provided).
• Slide the carriage bolt into the slot on each sensor.
• Insert the bolt through the hole in the sensor bracket and attach with the wing nut. The lenses on both sensors should point toward each other. Make sure the lens is not obstructed by the sensor bracket.

OPTION C FLOOR INSTALLATION

• Use an extension bracket (not provided) or wood block to raise the sensor bracket if needed.
• Carefully measure the position of both sensor brackets so they will be the same distance from the wall and unobstructed.
• Attach the sensor brackets to the floor using concrete anchors (not provided).
• Slide the carriage bolt into the slot on each sensor.
• Insert the bolt through the hole in the sensor bracket and attach with the wing nut. The lenses on both sensors should point toward each other. Make sure the lens is not obstructed by the sensor bracket

STEP 14 Wire the Safety Reversing Sensors

If your garage already has wires installed for the safety reversing sensors, proceed to page 26.

OPTION A INSTALLATION WITHOUT PRE-WIRING

• Run the wire from both sensors to the garage door opener. Attach the wire to the wall and ceiling with the staples.
• Strip 7/16 inch (11 mm) of insulation from each set of wires. Separate the wires. Twist the white wires together. Twist the white/black wires together.
• Insert the white wires into the white terminal on the garage door opener. Insert the white/black wires into the grey terminal on the garage door opener. To insert or remove the wires from the terminal, push in the tab with a screwdriver tip.

OPTION B PRE-WIRED INSTALLATION

• Cut the end of the safety reversing sensor wire, making sure there is enough wire to reach the pre-installed wires from the wall.
• Separate the safety reversing sensor wires and strip 7/16 inch (11 mm) of insulation from each end. Choose two of the pre-installed wires and strip 7/16 inch (11 mm) of insulation from each end. Make sure that you choose the same color pre-installed wires for each sensor.
• Connect the pre-installed wires to the sensor wires with wire nuts making sure the colors correspond for each sensor. For example, the white wire would connect to the yellow wire and the white/black wire would connect to the purple wire.
• At the garage door opener, strip 7/16 inch (11 mm) of insulation from each end of the wires previously chosen for the safety reversing sensors. Twist the like-colored wires together.
• Insert the wires connected to the white safety sensor wires to the white terminal on the garage door opener. Insert the wires that are connected to the white/black safety sensor wires to the grey terminal on the garage door opener.

STEP 15 Connect power

To avoid installation difficulties, do not run the opener at this time. To reduce the risk of electric shock, your garage door opener has a grounding type plug with a third grounding pin. This plug will only fit into a grounding type outlet. If the plug doesn’t fit into the outlet you have, contact a qualified electrician to install the proper outlet.

THERE ARE TWO OPTIONS FOR CONNECTING POWER: OPTION A TYPICAL WIRING

•  Plug in the garage door opener into a grounded outlet.
•  DO NOT run garage door opener at this time.

OPTION B PERMANENT WIRING
If permanent wiring is required by your local code, refer to the following procedure. To make a permanent connection through the 7/8 inch hole in the top of the motor unit (according to local code):

• Remove the motor unit cover screws and set the cover aside.
• Remove the attached 3-prong cord.
• Connect the black (line) wire to the screw on the brass terminal; the white (neutral) wire to the screw on the silver terminal; and the ground wire to the green ground screw. The opener must be grounded.
• Reinstall the cover.

STEP 16 Aligning the safety reversing sensors

The door will not close if the sensors have not been installed and aligned correctly. When the light beam is obstructed or misaligned while the door is closing, the door will reverse and the garage door opener lights will flash ten times. If the door is already open, it will not close.

• Check to make sure the LEDs in both sensors are glowing steadily. The LEDs in both sensors will glow steadily if they are aligned and wired correctly.
• The sensors can be aligned by loosening the wing nuts, aligning the sensors, and tightening the wing nuts.

IF THE AMBER LED ON THE SENDING SENSOR IS NOT GLOWING:

•  Make sure there is power to the garage door opener.
•  Make sure the sensor wire is not shorted/broken.
•  Make sure the sensor has been wired correctly: white wires to white terminal and white/black wires to grey terminal.

IF THE GREEN LED ON THE RECEIVING SENSOR IS NOT GLOWING:

•  Make sure the sensor wire is not shorted/broken.
•  Make sure the sensors are aligned.

STEP 17 Ensure the door control is wired correctly
If the door control has been installed and wired correctly, the command LED on the Multi-Function Control Panel will blink or the LED behind the push button on the door control will blink if installed correctly.

Adjustments

Introduction

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.

One-Piece Doors Only
When setting the UP travel for a one-piece door ensure that the door does not slant backwards when fully open (UP). If the door is slanted bac

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.

STEP 1 Program the Travel

• While programming, the UP and DOWN buttons can be used to move the door as needed.
• Press and hold the Adjustment Button until the UP Button begins to flash and/or a beep is heard.
• Press and hold the UP Button until the door is in the desired UP position.
• Once the door is in the desired UP position press and release the Adjustment Button. The garage door opener lights will flash twice and the DOWN Button will begin to flash. IMPORTANT NOTE: For one-piece door installations refer to page 29.
• Press and hold the DOWN button until the door is in the desired DOWN position.
• Once the door is in the desired DOWN position press and release the Adjustment Button. The garage door opener lights will flash twice and the UP Button will begin to flash.
• Press and release the UP Button. When the door travels to the programmed UP position, the DOWN Button will begin to flash.
• Press and release the DOWN Button. The door will travel to the programmed DOWN position. Programming is complete.

If the garage door opener lights are flashing 5 times during the steps for Program the Travel, the programming has timed out. If the garage door opener lights are flashing 10 times during the steps for Program the Travel, the safety reversing sensors are misaligned or obstructed (refer to page 28). When the sensors are aligned and unobstructed, cycle the door through a complete up and down cycle using the remote control or the UP and DOWN buttons. Programming is complete. If you are unable to operate the door up and down, repeat the steps for Programming the Travel.

STEP 2 Test the Safety Reversal System

•  With the door fully open, place a 1-1/2 inch (3.8 cm) board (or a 2×4 laid flat) on the floor, centered under the garage door.
•  Press the remote control push button to close the door. The door MUST reverse when it makes contact with the board.

If the door stops and does not reverse on the obstruction, increase the down travel (refer to Adjustment Step 1). Repeat the test. When the door reverses upon contact with the 1-1/2 inch board, remove the board and open/close the door 3 or 4 times to test the adjustment. If the garage door opener continues to fail the safety reversal test, call a trained door systems technician

STEP 3 Test the Protector System

• Open the door. Place the garage door opener carton in the path of the door.
• Press the remote control push button to close the door. The door will not move more than an inch (2.5 cm), and the garage door opener lights will flash 10 times.

The garage door opener will not close from a remote control if the LED in either safety reversing sensor is off (alerting you to the fact that the sensor is misaligned or obstructed). If the garage door opener closes the door when the safety reversing sensor is obstructed (and the sensors are no more than 6 inches [15 cm] above the floor), call for a trained door systems technician.

Operation

• READ AND FOLLOW ALL WARNINGS AND INSTRUCTIONS.
• ALWAYS keep remote controls out of reach of children. NEVER permit children to operate or play with garage door control push buttons or remote controls.
• ONLY activate garage door when it can be seen clearly, it is properly adjusted, and there are no obstructions to door travel.
• ALWAYS keep garage door in sight and away from people and objects until completely closed. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.
• NO ONE SHOULD GO UNDER A STOPPED, PARTIALLY OPENED DOOR.
• If possible, use emergency release handle to disengage trolley ONLY when garage door is CLOSED. Use caution when using this release with the door open. Weak or broken springs or unbalanced door could result in an open door falling rapidly and/or unexpectedly and increasing the risk of SEVERE INJURY or DEATH.
• NEVER use emergency release handle unless garage doorway is clear of persons and obstructions.
• NEVER use handle to pull garage door open or closed. If rope knot becomes untied, you could fall.
• After ANY adjustments are made, the safety reversal system MUST be tested.
• Safety reversal system MUST be tested every month. Garage door MUST reverse on contact with 1-1/2″ (3.8 cm) high object (or a 2×4 laid flat) on the floor. Failure to adjust the garage door opener properly increases the risk of SEVERE INJURY or DEATH.
• ALWAYS KEEP GARAGE DOOR PROPERLY BALANCED (see page 2). An improperly balanced door may NOT reverse when required and could result in SEVERE INJURY or DEATH.
• ALL repairs to cables, spring assemblies and other hardware, ALL of which are under EXTREME tension, MUST be made by a trained door systems technician.
• ALWAYS disconnect electric power to garage door opener BEFORE making ANY repairs or removing covers.
• This operator system is equipped with an unattended operation feature. The door could move unexpectedly. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.
• 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.

Features
Your garage door opener is equipped with features to provide you with greater control over your garage door operation.

MyQ®
MyQ® technology uses a 900MHz signal to provide two-way communication between the garage door opener and MyQ® enabled accessories. Your garage door opener is compatible with up to 8 MyQ® accessories. For Smartphone App control of your garage door opener and other MyQ® accessories, Chamberlain’s MyQ® Internet Gateway (model CIGBU) is required.

TIMER-TO-CLOSE (DO NOT enable on one-piece doors)
The Timer-to-Close feature is not available on all door controls. Below is a list of door controls with the Timer-to-Close feature: 041A7305-1 Smart Control Panel and 041A7327-1 Motion Detecting Control Panel The Timer-to-Close feature automatically closes the garage door after a specified time period. DO NOT enable TTC if operating a one-piece door. TTC is to be used ONLY with sectional doors. Factory default is set to off. The garage door opener will beep and the lights will flash before closing the door. The TTC feature will deactivate if the garage door encounters an obstruction twice; or the safety reversing sensors are incorrectly installed. The garage door will reverse open and WILL NOT close until the obstructions are clear or the safety reversing sensors are correctly installed. When the obstruction has been cleared or the safety reversing sensors have been aligned, the door will close when the garage door opener is activated. TTC WILL NOT work if the garage door opener is operating by battery power or if the safety reversing sensors are misaligned. This feature is NOT intended to be the primary method of closing the door. A keyless entry should be installed in the event of an accidental lock out when using this feature.

REMOTE CONTROLS AND DOOR CONTROLS (MyQ®)
Your garage door opener has already been programmed at the factory to operate with your remote control, which changes with each use, randomly accessing over 100 billion new codes. Compatible with MyQ® enabled accessories, see page 41. NOTE: Older Chamberlain remote controls, door controls, and third party products are not compatible.

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 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. 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. NOTE: Do not use halogen, short neck, or specialty light bulbs as these may overheat the end panel or light socket. Do not use LED bulbs as they may reduce the range or performance of your remote controls.

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 34.

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.
