balance. An unbalanced garage door may NOTreverse when required.
lNEVER try to loosen, move or adjust garage door, door springs, cables, pulleys, brackets or
their hardware, ALLof which are under EXTREME tension.
lDisable ALLlocksand remove ALLropes connected to garage door BEFORE installation and
operating garage door opener to avoid entanglement.
To prevent damage to garage door and opener:
lALWAYS disable locks BEFORE installing and operating the opener.
lONLY operate garage door opener at120V,60Hzto avoid malfunction and damage.
Before you begin:
1. Disable locks and remove anyropes 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 ofbalance, call a trained door systems
technician.
4. Check the seal on the bottomof the door. Any gap between the
floor and the bottom ofthe door must not exceed 1/4 inch (6 mm).
Otherwise, the safety reversal system may not work properly.
5. The opener should be installed above the center ofthe door. If
there is a torsion spring or center bearing plate in the way of the
header bracket, it may be installed within 4feet (1.2 m) to the left or
right of the door center. See page 9.

Installation
1 Determine the Header Bracket Location
To prevent possible SERIOUS INJURY or DEATH:
lHeader bracketMUSTbe RIGIDLY fastened to structural supporton header wall or ceiling,
otherwise garage door might NOT reverse when required. DO NOT install header bracket
over drywall.
lConcrete anchors MUST be used ifmounting header bracket or 2x4 into masonry.
lNEVER try to loosen, move or adjustgarage door, springs, cables,pulleys,brackets,or their
hardware, ALL of which are under EXTREME tension.
lALWAYS call a trained door systems technician if garage door binds,sticks,or is out of
balance. An unbalanced garage door mightNOT reverse when required.
1. Close the door and mark the inside vertical centerline ofthe garage door.
2. Extend the line onto the header wall above the door.
You can fasten the header bracketwithin 4 feet (1.22 m) ofthe left or right ofthe 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 isminimal. (Itmaybe 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.
3. 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.
NOTE: If the total number of inches exceeds the height available in your garage, use the maximum
height possible, or refer to page 10 for ceiling installation.

6 Install the Light Bulb
To prevent possible OVERHEATING of the endpanel or light socket:
lUse ONLY A19 incandescent (60W maximum) or compact fluorescent (23W maximum) light
bulbs.
lDO NOT use incandescent bulbs larger than 60W.
To preventdamage to the opener:
lDO NOT use compact fluorescent light bulbs larger than 23W (100W) equivalent.
lDO NOT use halogen bulbs.
lDO NOT use short neck or specialty light bulbs.
1. Press the triangular release buttons and swing the lens open.
2. Insert an A19 incandescent (60W maximum) or compact fluorescent (23W, 100W equivalent)
light bulb into the light socket.
3. Swing the lens shut until triangular buttons click into place.
NOTE: Do not use halogen, short neck, or specialty light bulbs as these may overheat the unit. The use
of LED bulbs may reduce the operating range or performance of your remote controls.
7 Attach the Emergency Release Rope and Handle
To prevent possible SERIOUS INJURY or DEATH from a falling garage door:
lIf possible, use emergency release handle to disengage trolley ONLY when garage door is
CLOSED. Weak or broken springs or unbalanced door could resultin an open door falling
rapidlyand/or unexpectedly.
lNEVER use emergency release handle unless garage doorway is clear of persons and
obstructions.
lNEVER use handle to pull door open or closed. If rope knot becomes untied,you could fall.
1. Insert one end of the emergencyrelease rope through the handle. Make sure that “NOTICE”
is right side up. Secure with an overhand knot at least1" (2.5 cm) from the end ofthe 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 (1.83 m) above floor, avoiding
contactwith 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.

8 Install the Door Bracket
Fiberglass, aluminum or lightweight steel garage doors WILL REQUIRE reinforcement BEFORE
installation ofdoor 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
reinforcementbrace should cover the heightof 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.
SECTIONALDOORS
1. Center the door bracketon the previouslymarked vertical centerline used for the header
bracket installation. Note correct UP placement, as stamped inside the bracket.
2. Position the top edge ofthe bracket2"-4" (5-10 cm) below the top edge ofthe door, OR
directlybelow 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:
lDrill 3/16" fastening holes.Secure the door bracket using the two selfthreading screws.
(Figure1)
lAlternately, use two 5/16" bolts, lock washers and nuts (not provided). (Figure2)
Metal, insulated or light weight factory reinforced doors:
lDrill 3/16" fastening holes. Secure the door bracket using the self-threading screws. (Figure3)
Wood Doors:
lUse top and bottom or side to side door bracketholes. Drill 5/16” holes through the door and
secure bracket with 5/16"-18 x 2" carriage bolts, lock washers and nuts(notprovided).
(Figure4)
NOTE: The 1/4"-14 x 5/8" self-threading screws are not intended for use on wood doors.

13 Install the Protector System®
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:
lCorrectly connect and align the safety reversing sensor. This required safety device MUST NOT
be disabled.
lInstall 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 lightbeam to the receiving sensor (with
a green LED). Ifan obstruction breaks the light beam while the door isclosing, 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
offand 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.
Wheninstallingthe safety reversingsensors check the following:
lSensors are installed inside the garage, one on either side of the door.
lSensors are facing each other with the lenses aligned and the receiving sensor lens does not
receive direct sunlight.
lSensors are no more than 6 inches (15 cm) above the floor and the light beam is
unobstructed.
