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

1Determine 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 mark the inside vertical centerline of the garage door.
1.2 Extend the line onto the header wall above the door.
Youcan fasten the header bracket within 4 feet (1.22 m) of the left or right of the door
center only if a torsion spring orcenter bearing plate is in the way; or you can attach it to
the ceilingwhen clearance is minimal. (It may be mounted onthe 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.
1.3 Open your door to the highestpoint oftravel asshown.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.

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 bracketto structural
supportsbefore installing the opener. This
bracket and fastening hardware are notprovided.
Instructions below are for attaching the garage
door opener directly to structural supports.
5.1 Measure the distance from each side of the
motor unit to the structural support.
5.2 Cut both pieces of the hanging bracket to
required lengths.
5.3 Drill 3/16" pilot holes in the structural
supports.
5.4 Attach one end ofeach bracket to a
support with 5/16"-18x1-7/8" lag screws
(not provided).
5.5 Fasten the opener to the hanging brackets
with 5/16"-18x7/8" hex bolts, lock washers
and nuts.
5.6 Checkto 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).
5.7 Remove the 2x4. Operate the door
manually.If the door hitsthe rail, raise the
header bracket.
NOTE: DO NOT connect power to opener at this

• NEVER use handle to pull door open or closed. If rope knotbecomesuntied, you could fall.
7.1 Insert one end ofthe emergencyrelease rope
through the handle. Make sure that “NOTICE” is
rightside up. Tie a knot atleast1 inch (2.5 cm) from
the end of the emergency release rope.
7.2 Insert the other end of the emergency release rope
through the hole in the trolleyrelease arm. Mount
the emergency release within reach, but at least 6
feet (1.83 m) above the 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.

Fiberglass, aluminum or lightweight steel garage doors WILLREQUIRE reinforcement BEFORE
installation of door bracket.Contactyour door manufacturer for reinforcement kit.
Figure 1 shows one piece of angle iron as the horizontal brace.
For the vertical brace,2 pieces ofangle iron are used to create a
U-shaped support. The bestsolution is to checkwith your garage
door manufacturer for an opener installation door 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.

8.2 Position the top edge ofthe bracket 2"-4" (5-10 cm) belowthe top edge ofthe door, OR directly below
any structural support acrossthe top of the door.
8.3 Mark, drill holes and install as follows, depending on your door’s construction:
Metal orlight weight doors using a vertical angle ironbrace between the doorpanelsupport
and the door bracket:
• Drill 3/16" fastening holes.Secure the door bracketusing the two self threading screws.
(Figure 2)
• Alternately, use two 5/16" bolts, lock washers and nuts (not provided). (Figure 3)
Metal, insulated or light weight factory reinforced doors:
• Drill 3/16" fastening holes.Secure the door bracketusing the self-threading screws.(Figure 4)
Wood Doors:
• Use top and bottom or side to side door bracketholes.Drill 5/16” holes through the door and

Introduction
Be sure power is NOT connected to the garage
door opener BEFORE installing the safety
reversing sensor.
To prevent SERIOUS INJURY or DEATHfrom
closing garage door:
• Correctly connectand align the safety
reversing sensor. This required safety
device MUST NOT be disabled.
• Install the 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
The safety reversing sensors must be connected and aligned correctly before the garage door openerwillmove inthe down direction.
The sending sensor (with an amber LED) transmits an invisible lightbeam to the receiving sensor (with a green LED). Ifan obstruction breaksthe 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.
Wheninstalling the safety reversingsensors check the following:
• Sensors are installed inside the garage,one on either side of the door.
• Sensors are facing each other with the lensesaligned and the receiving sensor lens does not receive directsunlight.
• Sensors are no more than 6 inches (15 cm) above the floor and the lightbeam is unobstructed.

1Install the Safety Reversing Sensors
The safetyreversing sensors can be attached to the door track, the wall,or the floor. If the door track will not support the sensor bracket a wall installation is recommended. Choose one of the following installations.

Carriage Bolt
1/4"-20x1/2"
Wing Nut

Lag Screw 1/4"x1-1/2"
Hex Bolt 1/4"-20x5/8"

OPTION A DOOR TRACK INSTALLATION
1.1A Slide the curved arms of the sensor
bracketaround the edge ofthe door
track.Snap into place so that the
sensor bracket is flush against the
track.
1.2A Slide the carriage boltinto the slot on
each sensor.
Carriage Bolt
1/4" - 20 x 1/2"
1.3A 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.
Wing Nut
1/4" - 20
OPTION B WALLINSTALLATION
If additional clearance isneeded an extension bracket (not provided) or wood blocks can be used. Make sure each brackethas the same amountof clearance so they will align correctly.
1.1B 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.

1.2B Drill 3/16 inch pilot holes for each sensor
bracket and attach the sensor brackets
to the wall using lag screws (not
provided).
