SECTIONAL DOOR INSTALLATION
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 finished 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 floor 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 Outside Quick
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". 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 to the left or right of
the door center. See Installation Steps 1 and 11.

INSTALLATION STEP 1
Determine the Header Bracket
Location
Installation procedures vary according to garage door
types. Follow the instructions which apply to your
door.
SECTIONAL DOOR
AND ONE-PIECE DOOR WITH TRACK
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
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 14) when clearance is minimal. (It may be
mounted on the wall upside down if necessary,
to gain approximately 1/2".)
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 2" above the high point. This height
will provide travel clearance for the top edge of the
door.
Proceed to Step 2, page 14. One-piece
door with
horizontal
track
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.

INSTALLATION STEP 5
Hang the Opener
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"-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.
8.Grease the top and underside of the rail surface
where the trolley slides with rail grease.
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 the door at a
minimum height of 5 feet where small children cannot
reach, and away from moving parts of the 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" 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" 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" 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 the power and operate the
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. See Safety Reversing Sensor Instructions
beginning on page 21.

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 up to a 100 watt maximum light bulb in each
socket. 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.
•If the bulbs burn out prematurely due to vibration,
replace with a Garage Door Opener bulb.
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" 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 above
the floor. 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
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 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.
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.
