Installation
1 Determine the Header Bracket Location
To prevent possible SERIOUS INJURY or DEATH:
lHeader 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.
lConcrete anchors MUST be used if mounting header bracket or 2x4 into
masonry.
lNEVER try to loosen, move or adjust garage 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 might NOT reverse when
required.
lDO 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 10 for ceiling installation.

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.
SECTIONALDOORS
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:
lDrill 3/16" fastening holes. Secure the door bracket using the two self threading
screws. (Figure1)
lAlternately, use two 5/16"-18x2" 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

1. 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 staples (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.
2. Strip 7/16 inch (11 mm) of insulation from the end of the wire near the garage
door opener.
3. Connect the wire to the red and white terminals on the garage door opener. To
insert or release wires from the terminal, push in the tab with screwdriver tip.

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:
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 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:
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.

The safety reversing 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.
OPTION A - DOOR TRACK INSTALLATION
1. 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.
2. Slide the carriage bolt into the slot on each sensor.
3. 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 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.
1. 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.
2. Drill 3/16 inch pilot holes for each sensor bracket and attach the sensor brackets
to the wall using lag screws (not provided).
3. Slide the carriage bolt into the slot on each sensor.
4. 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.
