SECTIONA DOOR INSTA ATION
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 – 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 0 – Depending upon garage
construction, extension brackets or wood blocks
may be needed to install sensors.
• Installation Step 0 – 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 /4". Otherwise, the safety
reversal system may not work properly. See
Adjustment Step 3. Floor or door should be
repaired.
SECTIONA DOOR INSTA ATIONS
• Do you have a steel, aluminum, fiberglass or glass
panel door? If so, horizontal and vertical reinforce-
ment is required (Installation Step ).
• 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 and .
• If your door is more than 7 feet high, see rail

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 , page 14.

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 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 possi le SERIOUS INJURY from a falling
garage door opener, fasten it SECURELY to structural
supports of the garage. Concrete anchors MUST e used
if installing any rackets into masonry.

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.
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 2 and white/red
wire to the 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 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.
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

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 a oid installation difficulties, do not run the
opener at this time.
