Installation

To prevent possible SERIOUS INJURYor DEATH:

• Header bracketMUSTbe RIGIDLY fastened to structural supporton header wall or ceiling, otherwise garage door might NOTreverse when required. DO NOT install header bracketover drywall.

• Concrete anchors MUST be used if mounting header bracket or 2x4 into masonry.

• NEVER try to loosen,moveor 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 mightNOTreverse 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.

1 Determine the header bracket location

NOTE: Ifyou are installing the garage door opener on a one-piece door, visit www.liftmaster.com for installation instructions.

1.1 Close the door and markthe inside vertical centerline of the garage door.

1.2 Extend the line onto the header wall above the door.

Youcan fastenthe header bracket within4 feet (1.22 m) of the left orright of the door center onlyifa torsionspringorcenterbearingplateis inthe way; oryoucan attachitto the ceilingwhen clearance is minimal.(It may be mountedonthe wall upside down if necessary, to gain approximately 1/2" (1 cm).

Ifyou need to install the header bracket on a 2x4 (on wall or ceiling), use lag screws(not provided) tosecurelyfasten the 2x4 to structural supports.

1.3 Open your door to the highestpoint of travel as shown.Draw an intersecting horizontal line on

the header wall 2" (5 cm) abovethe high point. This height willprovide travel clearance for the top edge of the door.

NOTE: Ifthe total number of inches exceeds the heightavailable in your garage, use the maximum height possible, or refer to page 8 for ceiling installation.

7 Attach the emergency release rope and handle

To prevent possible SERIOUS INJURYor DEATH from a falling garage door:

• Ifpossible,use emergency releasehandle todisengage 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.

• NEVER use emergencyrelease handle unless garage doorwayisclear of personsand obstructions.

• NEVER use handle to pull door open or closed. If rope knotbecomesuntied, you could fall.

7.1 Insertone end of the emergencyrelease rope

through the handle. Make sure that “NOTICE” is right side up. Tie a knotat least 1 inch(2.5 cm) from the end of the emergencyrelease rope.

7.2 Insertthe other end of the emergencyrelease rope

through the hole in the trolley release arm. Mount the emergency releasewithin reach, but atleast6 feet(1.83 m) above the floor, avoiding contactwith vehiclesto prevent accidental release and secure witha knot.

NOTE: Ifit is necessaryto cut the emergency release rope, seal the cut end with a match or lighter to prevent unraveling. Ensure the emergencyrelease rope and handle are above the top ofall vehicles to avoid entanglement.

Metal orlight weight doors usinga vertical angle iron brace between the doorpanel support andthe doorbracket:

• Drill 3/16" fastening holes. Secure the door bracketusing the two self threading screws. (Figure 2)

• Alternately, use two 5/16" bolts,lockwashers and nuts (not provided). (Figure 3)

Metal,insulated orlight weightfactory reinforced doors:

• Drill 3/16" fastening holes. Secure the door bracketusing the self-threading screws.(Figure 4)

Introduction

Be sure power is NOTconnectedto the garage door opener BEFORE installing the safety reversing sensor. To prevent SERIOUS INJURY or DEATH from closing garage door:

• Correctlyconnectand align the safety reversing sensor. This required safety device MUSTNOT be disabled.

• Installthe safetyreversing sensor so beam is NO HIGHER than 6" (15 cm) above garage floor.

Install the Protector System

IMPORTANTINFORMATIONABOUTTHESAFETYREVERSINGSENSORS Thesafety reversing sensors must be connected andalignedcorrectly before the garage dooropener willmove in the down direction.

The sending sensor (with an amber LED)transmits an invisible light beam tothe receiving sensor (witha green LED). If an obstruction breaksthe light beam while the door is closing, the door will stop and reverse to the full open position,and thegarage door opener lightswill flash 10 times.

NOTE: For energyefficiency 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 LEDswill light. The garage door opener will not go into the sleep mode until the garage door opener has completed 5 cycles upon power up.

Wheninstalling the safety reversingsensors check the following:

• Sensorsare installed inside the garage, one on eitherside of the door.

• Sensorsare facing eachother with the lensesaligned and the receiving sensor lensdoes not receive directsunlight.

• Sensorsare no more than 6 inches (15 cm) above thefloor and the lightbeam is unobstructed.

Power

1 Connect Power

To prevent possible SERIOUS INJURY or DEATH from electrocution or fire:

• Be sure power is NOT connectedtotheopener, anddisconnectpower to circuit BEFORE removing cover toestablish permanent wiring connection.

• Garage door installation andwiring MUST be in compliancewith ALL local electrical and building codes.

• NEVER use an extension cord, 2-wire adapter, or changeplugin any way to make it fit outlet.Be sure the opener is grounded.

To avoid installation difficulties, do not activate thegarage door opener at this time.

To reduce the risk of electric shock, your garage door opener has a grounding type plug witha third grounding pin. This plug will only fit into a grounding type outlet. If the plug doesn’t fit intoyour outlet,contacta qualified electricianto install the proper outlet.

INTRODUCTION

Your garage door opener is designed with electronic controlsto make setup and adjustmentseasy. The adjustmentsallow you to programwhere the door will stop in the open (UP) and close(DOWN) position. The electronic controlssense the amount offorce required to open and closethe door. The force is adjusted automatically when you program thetravel.

NOTE: Ifanything interferes with the door’s upward travel it will stop. Ifanything interferes with the door’sdownward travel, it will reverse.

Adjustments

2 Test the Safety Reversal System

Withouta properly installed safetyreversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door.

• Safetyreversal system MUST be tested every month.

• After ANY adjustmentsare made,the safety reversal system MUST be tested. Door MUST reverse on contactwith 1-1/2"(3.8 cm) high object (or 2x4 laid flat)on the floor.

2.1 With the door fully open, placea 1-1/2

inch (3.8 cm) board (or a 2x4 laid flat) on the floor, centered under the garage door.

2.2 Press the remote controlpush button to

close the door.The door MUSTreverse when it makes contactwiththe board.

Ifthedoor stops and does notreverse on the obstruction,increase the down travel (refer to Adjustment Step 1).

Repeat the test.When the door reverses upon contact with the 1-1/2inch board, remove the board and open/close the door 3 or 4 times to testthe adjustment.

Ifthegarage door opener continuesto fail the safetyreversaltest, call a trained door systemstechnician.

3 Test the Protector System

Withouta properly installed safetyreversing sensor,persons (particularly small children) could be SERIOUSLY INJUREDor KILLED by a closing garage door.

3.1 Open the door. Place the garage door
