Before you begin:
• Disable locks.
• Remove any ropes connected to garage door.
• Complete the following test to make sure your garage
door is balanced and is not sticking or binding:
1. Lift the door about halfway as shown. Release the
door. If balanced, it should stay in place, supported
entirely by its springs.
2. Raise and lower the door to see if there is any
binding or sticking.
If your door binds, sticks, or is out of balance, call a
trained door systems technician.

Planning
Identify the type and height of your garage door. Survey
your garage area to see if any of the conditions below
apply to your installation. Additional materials may be
required. You may find it helpful to refer back to this page
and the accompanying illustrations as you proceed with
the installation of your opener.
Depending on your requirements, there are several
installation steps which may call for materials or hardware
not included in the carton.
•
Installation Step 1 – Look at the wall or ceiling above
the garage door. The header bracket must be securely
fastened to structural supports.
•
Installation Step 5 – Do you have a fi
nished ceiling in
your garage? If so, a support bracket and additional
fastening hardware may be required.
• Installation Step 10 – Depending upon garage
construction, extension brackets or wood blocks may
be needed to install sensors.
• Installation Step 10 – Alternate fl
oor mounting of
the safety reversing sensor will require hardware not
provided.
•
Do you have an access door in addition to the garage
door? If not, Model 7702CB Emergency Key Release is
required. See Accessories page.
• Look at the garage door where it meets the floor. Any
gap between the floor and the bottom of the door must
not exceed 1/4" (6 mm). Otherwise, the safety reversal
system may not work properly. See Adjustment Step 3.
Floor or door should be repaired.
SECTIONAL DOOR INSTALLATIONS
• Do you have a steel, aluminum, fiberglass or glass
panel door? If so, horizontal and vertical reinforcement
is required (Installation Step 11).
• The opener should be installed above the center of the
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 Installation Steps 1 and 11.
• If your door is more than 7 feet (2.1 m) high, see rail
extension kits listed on Accessories page.

ASSEMBLY STEP 1
Assemble the Rail & Install the Trolley
To avoid installation difficulties, do not run the garage
door opener until instructed to do so.
The front rail has a cut out “window” at the door end
(see illustration). The hole above this window is larger on
the top of the rail than on the bottom. A smaller hole
3-1/2" (8.9 cm) away is close to the rail edge. Rotate the
back rail so it has a similar hole close to the opposite
edge, about 4-3/4" (12 cm) from the far end.
1. Remove the straight door arm and hanging bracket
packaged inside the front rail and set aside for
Installation Step 5 and 12. NOTE: To prevent INJURY
while unpacking the rail carefully remove the straight
door arm stored within the rail section.
2. Align the rail sections on a flat surface as shown and
slide the tapered ends into the larger ones. Tabs along
the side will lock into place.
To prevent INJURY from pinching, keep hands and
fingers away from the joints while assembling the rail.
3. Place the motor unit on packing material to protect
the cover, and rest the back end of the rail on top.
For convenience, put a support under the front end of
the rail.
4. As a temporary stop, insert a screwdriver into the hole
10" (25 cm) from the front end of the rail, as shown.
5. Check to be sure there are 4 plastic wear pads inside
the inner trolley. If they became loose during shipping,
check all packing material. Snap them back into
position as shown.
6. Slide the trolley assembly along the rail from the back
end to the screwdriver.

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.

INSTALLATION STEP 5
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
(Figures 2 and 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.

INSTALLATION STEP 7
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 socket.
Light bulb size should be A19, standard 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.
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.
To prevent possible SERIOUS INJURY or DEATH from
a falling garage door:
• If possible, use emergency release handle to
disengage 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 emergency release handle unless garage
doorway is clear of persons and obstructions.
• NEVER use handle to pull door open or closed. If rope
knot becomes untied, you could fall.
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 (1.8 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 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.
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 doesn’t 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.

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.

INSTALLING THE BRACKETS
Be sure power to the opener is disconnected. Install
and align the brackets so the sensors will face each other
across the garage door, with the beam no higher than
6" (15 cm) above the floor. They may be installed in one of
three ways, as follows.
Garage door track installation (preferred):
• Slip the curved arms over the rounded edge of each
door track, with the curved arms facing the door. Snap
into place against the side of the track. It should lie
flush, with the lip hugging the back edge of the track,
as shown in Figure 1.
If your door track will not support the bracket securely,
wall installation is recommended.
Wall installation (Figures 2 and 3):
• Place the bracket against the wall with curved arms
facing the door. Be sure there is enough clearance for
the sensor beam to be unobstructed.
• If additional depth is needed, an extension bracket (see
Accessories) or wood blocks can be used.
• Use bracket mounting holes as a template to locate and
drill (2) 3/16" diameter pilot holes on the wall at each
side of the door, no higher than 6" (15 cm) above the
floor.
• Attach brackets to wall with lag screws (not provided).
• If using extension brackets or wood blocks, adjust
right and left assemblies to the same distance out from
the mounting surface. Make sure all door hardware
obstructions are cleared.
Floor installation (Figure 4):
• Use wood blocks or extension brackets (see
Accessories) to elevate sensor brackets so the lenses
will be no higher than 6" (15 cm) above the floor.
• Carefully measure and place right and left assemblies
at the same distance out from the wall. Be sure all door
hardware obstructions are cleared.
• Fasten to the floor with concrete anchors as shown.
