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

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 T-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.

Install the Door Control
Locate the door control within sight of the door at a
minimum height of 5 feet where small children
cannot reach, and away from all moving parts of the
door and door hardware.
1. Strip 1/4" of insulation from one end of the bell
wire. Connect it to the two screw terminals on the
back of the door control by color: white wire to 2
and white/red wire to 1.
2. Fasten the Lighted Door Control Button securely
with 6ABx1-1/2" screws. If installing into drywall,
drill 5/32" holes and use the anchors provided.
3. Run the bell wire up the wall and across the
ceiling to the opener. Use insulated staples to
secure the wire in several places. Be careful not to
pierce the wire with a staple, creating a short or
open circuit.
4. Receiver terminal screws and the antenna are
located on the back panel of the motor unit.
Position the antenna wire as shown.
5. Then connect the bell wire to the opener terminal
screws: white to 2 and white/red to 1.
6. Use tacks or staples to permanently attach the
entrapment warning label to the wall near the door
control, and the manual release/safety reverse test
in a prominent location on the inside of the 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 Light and Lens
INSTALL THE LIGHT
•Install a 75 watt maximum light bulb in the socket.
The light will turn ON and remain lit for
approximately 4-1/2 minutes when power is
connected. Then the light will turn OFF.
•Use standard neck Garage Door Opener bulbs for
replacement.
NOTE: Use only standard light bulbs. The use of
short neck or specialty light bulbs may overheat the
endpanel or light socket.
INSTALL THE LENS
•Locate and loosen (approximately 1/8") the two
screws near top of opener front panel.
•Position lens against panel with slotted tabs
directly below screws. Slide lens up to seat tabs
behind screws.
•Snap bottom tabs of lens into panel slots.
•Retighten top panel screws to secure lens.
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.
