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 53702 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" (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.
SECTIONAL DOOR INSTALLATION
Horizontal and vertical reinforcement
is needed for lightweight garage doors
(fiberglass, steel, aluminum, door with
glass panels, etc.). See page 23 for details.

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, away from moving parts of door and door
hardware. If installing into drywall, drill 5/32" holes and
use the anchors provided.
1. Strip 1/4" (6 mm) of insulation from one end of bell
wire and connect to the two terminal screws on
back of door control by color: white to 2 and
white/red to 1.
2. Door Control Button: Fasten securely with
screws 6ABx1-1/2".
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. Connect the bell wire to the terminal screws on the
motor unit panel: white to 2; white/red to 1.
5. Position the antenna wire as shown.

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.
To prevent possible SERIOUSINJURYor DEATHfrom
electrocution or fire:
• Besure power is not connectedto the opener,and
disconnect powerto circuit BEFOREremoving cover to
establish permanentwiring connection.
• Garagedoor installation and wiring MUSTbe in
compliancewith all localelectrical and building codes.
• NEVERusean extensioncord, 2-wire adapter,or
changeplug in any way to makeit fit outlet. Besure
the opener is grounded.

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 green 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.
Be sure power is not connectedto the garage door
opener BEFOREinstalling the safety reversingsensor.
To prevent SERIOUSINJURYor DEATHfrom a closing
garagedoor:
• Correctly connect and align the safety reversing
sensor.This required safety device MUSTNOTbe
disabled.
• Install the safety reversing sensor so beam is NO
HIGHERthan 6" (15 cm) abovegarage floor.
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.
