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 – 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 187 2 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 reinforce-
ment 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 (1.22 m) to the left or
right of the door center. See Installation Steps 1
and 11.

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" ( .9cm) 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. A 3-piece rail uses two back rails.
1. Remove the straight door arm, hanging brackets
and clevis pin packaged inside the front rail and
set aside for Installation Step and 12.
2. Align the rail sections on a flat surface exactly as
shown and slide the tapered ends into the larger
ones. Tabs along the side will lock into place.
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 trolley stop, clamp a locking pliers
onto the rail, 8" (20 cm) from the center of the
idler pulley hole, as shown.
. 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. Connect the inner and outer trolleys as shown.
7. Slide the trolley assembly along the rail from the
back end to the locked pliers.

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.
See Accessories).
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.

INSTALLATION STEP 6
Install the Door Control
Locate door control within sight of door, at a
minimum height of 5 feet (1.52 m) where small
children cannot reach, away from moving parts of
door and door hardware. If installing into drywall, drill
5/32" holes and use the anchors provided. For
pre-wired installations (as in new home
construction), it may be mounted to a single gang
bo (Figure 2).
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
2 and white/red wire to the 1.
2. Remove white cover by gently prying at slot in top
of the cover with a small flat head screwdriver.
Fasten with 6AB 1-1/4"self-tapping screws
(drywall installation) or 6-32 1" machine screws
(into gang bo ) as follows:
• 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.
• Drill and install top screw with care to avoid
cracking plastic housing. Do not over tighten.
• Insert top tabs and snap on cover.
3. (For 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.
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. Position the antenna wire as shown.
6. 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.
To prevent possi le SERIOUS INJURY or DEATH from
electrocution:
• Be sure power is not connected BEFORE installing door
control.
• Connect ONLY to 24 VOLT low voltage wires.
To prevent possi le SERIOUS INJURY or DEATH from a
closing garage door:
• Install door control within sight of garage door, out of
reach of children at a minimum height of 5 feet
(1.52 m), and away from all moving parts of door.
• NEVER permit children to operate or play with door
control push uttons or remote control transmitters.
• Activate door ONLY when it can e seen clearly, is
properly adjusted, and there are no o structions to door
travel.
• ALWAYS keep garage door in sight until completely
closed. NEVER permit anyone to cross path of closing
garage door.

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.
