INSTALLATION STEP 1
Determine the Header Bracket
Location
Installation procedures vary according to garage door
types. Follow the instructions which apply to your
door.
1. Close the door and mark the inside vertical
centerline of the garage door.
2. 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 2x4
(on wall or ceiling), use lag screws (not provided)
to securely fasten the 2x4 to structural supports as
shown here and on page 13.
3. Open your door to the highest point of travel as
shown. Draw an intersecting horizontal line on the
header wall 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.
To prevent possible SERIOUS INJURY or DEATH:
• Header 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.
• 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 out of balance. An
unbalanced garage door might not reverse when
required.

Hang the Opener
Three representative installations are shown. Yours
may be different. Hanging brackets should be angled
(Figure 1) to provide rigid support. On finished
ceilings (Figure 2 and Figure 3), 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"-18x1-7/8" lag screws.
5. Fasten the opener to the hanging brackets with
5/16"-18x7/8" 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.
To avoid possible SERIOUS INJURY from a falling
garage door opener, fasten it SECURELY to structural
supports of the garage. Concrete anchors MUST be used
if installing ANY brackets into masonry.

INSTALLATION STEP 6
Install the Door Control
Locate door control within sight of door at a
minimum height of 5 feet (1.5 m) where small
children cannot reach, and away from moving parts
of door and door hardware. The installation surface
must be smooth and flat. If installing into drywall
(Figure 1), drill 5/32" holes and use anchors
provided. For pre-wired installations (as in new home
construction), it may be mounted to a single gang
box (Figure 2). NOTE: After installation, a green or
amber indicator light behind the cover will indicate
proper connection. If not lit, the Lock and Light
features will not function (reverse wires to correct).
1. Strip 7/16" (11 mm) of insulation from one end of
bell wire and connect to the two screw terminals
on back of door control by color: white wire to
WHT and white/red wire to the RED (Figure 3).
2. Remove white cover by gently prying on a side
corner near the top of the cover with a small flat
head screwdriver (Figure 4). Fasten with
6ABx1-1/4" self-tapping screws (drywall
installation) or 6-32x1" machine screws (into gang
box) as follows:
• Drill and install bottom screw, allowing 1/8"
(3 mm) to protrude above wall surface.
• Position bottom of door control on screw head
and slide down to secure. Adjust screw for snug
fit.
• Install top screw with care to avoid
cracking plastic housing. Do not overtighten.
• Insert bottom tabs and snap on cover.
NOTE: The push bar may stick if the door control
is not mounted on a smooth surface. If a click is
not heard when pressing the push bar, loosen the
two mounting screws or relocate the door control
to a smoother surface.
3. (Standard installation only) Run bell wire up wall
and across ceiling to motor unit. Use insulated
staples to secure wire in several places. Do not
pierce wire with a staple, creating a short or open
circuit.
4. Strip 7/16" (11 mm) of insulation from end of bell
wire. Connect bell wire to the quick-connect
terminals as follows: white to white and white/red to
red (Figure 5).
NOTE: When connecting multiple door controls to
the opener, twist same color wires together. Insert
wires into quick-connect holes: white to white and
red/white to red.
5. Use tacks or staples to permanently attach
entrapment warning label to wall near door control,
and manual release/safety reverse test label in a
prominent location on inside of garage door.
NOTE: DO NOT connect power and operate opener
at this time. The trolley will travel to the full open
position but will not return to the close position until
the sensor beam is connected and properly aligned.

Install the Lights
• Press the release tabs on both sides of lens.
Gently rotate lens back and downward until the
lens hinge is in the fully open position. Do not
remove the lens.
• Install a 100 watt maximum light bulb in each

neck only. The lights will turn ON and remain lit for
approximately 4-1/2 minutes when power is
connected. Then the lights will turn OFF.
• Reverse the procedure to close the lens.
• Use A19, standard neck garage door opener bulbs
for replacement.
NOTE: Use only standard light bulbs. The use of
short neck or speciality light bulbs may overheat the
endpanel or light socket.
INSTALLATION STEP 8
Attach the Emergency Release
Rope and Handle
• Thread one end of the rope through the hole in the
top of the red handle so “NOTICE” reads right side
up as shown. Secure with an overhand knot at
least 1" (2.5 cm) from the end of the rope to
prevent slipping.
• Thread the other end of the rope through the hole
in the release arm of the outer trolley.
• Adjust rope length so the handle is 6 feet (1.83 m)
above the floor. Ensure that the rope and handle
clear the tops of all vehicles to avoid
entanglement. Secure with an overhand knot.
NOTE: If it is necessary to cut the rope, heat seal
the cut end with a match or lighter to prevent
unraveling.
To prevent possible OVERHEATING of the endpanel or
light socket:
• DO NOT use short neck or specialty light bulbs.
• DO NOT use halogen bulbs. Use ONLY incandescent.
To prevent damage to the opener:
• DO NOT use bulbs larger than 100W.
• ONLY use A19 size bulbs.

INSTALLATION STEP 9
Electrical Requirements
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 does not fit into the outlet you
have, contact a qualified electrician to install the
proper outlet.
If permanent wiring is required by your local
code, refer to the following procedure.
To make a permanent connection through the 7/8"
hole in the top of the motor unit:
• 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.
To avoid installation difficulties, do not run the
opener at this time.
RIGHT WRONG
To prevent possible SERIOUS INJURY or DEATH from
electrocution or fire:
• Be sure power is not connected to the opener, and
disconnect power to circuit BEFORE removing cover to
establish permanent wiring connection.
• Garage door installation and wiring MUST be in
compliance with ALL local electrical and building
codes.
• NEVER use an extension cord, 2-wire adapter, or
change plug in ANY way to make it fit outlet. Be sure
the opener is grounded.

Safety Reversing Sensor
6" (15 cm) max. above floor Safety Reversing Sensor
6" (15 cm) max. above floor
Facing the door from inside the garage
INSTALLATION STEP 10
Install The Protector System®
The safety reversing sensor must be connected
and aligned correctly before the garage door
opener will move in the down direction.
IMPORTANT INFORMATION ABOUT
THE SAFETY REVERSING SENSOR
When properly connected and aligned, the sensor
will detect an obstacle in the path of its electronic
beam. The sending eye (with an amber indicator
light) transmits an invisible light beam to the
receiving eye (with a green indicator light). If an
obstruction breaks the light beam while the door is
closing, the door will stop and reverse to full open
position, and the opener lights will flash 10 times.
The units must be installed inside the garage so that
the sending and receiving eyes face each other
across the door, no more than 6" (15 cm) above the
floor. Either can be installed on the left or right of the
door as long as the sun never shines directly into the
receiving eye lens.
The mounting brackets are designed to clip onto the
track of sectional garage doors without additional
hardware.
If it is necessary to mount the units on the wall, the
brackets must be securely fastened to a solid
surface such as the wall framing. Extension brackets
(see accessories) are available if needed. If
installing in masonry construction, add a piece of
wood at each location to avoid drilling extra holes in
masonry if repositioning is necessary.
The invisible light beam path must be unobstructed.
No part of the garage door (or door tracks, springs,
hinges, rollers or other hardware) may interrupt the
beam while the door is closing.
Be sure power is not connected to the garage door
opener BEFORE installing the safety reversing sensor.
To prevent SERIOUS INJURY or DEATH from a closing
garage door:
• Correctly connect and align the safety reversing
sensor. This required safety device MUST NOT be
disabled.
• Install the safety reversing sensor so beam is NO
HIGHER than 6" (15 cm) above garage floor.
