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 6 - Do you have a finished ceiling
in your garage? If so, a support bracket and
additional fastening hardware may be required.
• Installation Step 4 - Depending upon garage
construction, extension brackets or wood blocks
may be needed to install sensors.
• Installation Step 4 -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 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" (0.625 cm). 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 12).
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 (1.20 m) to the left or
right of the door center. See Installation Steps 1
and 12.
• If your door is more than 7 feet (2.10 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 24 for details.

INSTALLATION STEP 4
Install the Safety Reversing Sensor
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 orange 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 wilt 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 poweris not connectedto the garage door
opener BEFOREinstalling the safety reversing sensor.
• Toprevent 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 beamis 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 ifneeded, 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.

INSTALLING THE BRACKETS
Be sure power to the opener is disconnected.
install and align the brackets so the sensors will face
each other across the garage door, with the beam no
higher than 6" (15 cm) above the floor. They may be
installed in one of three ways, as follows.
Garage door track installation (preferred):
• Slip the curved arms over the rounded edge of
each door track, with the curved arms facing the
door. Snap into place against the side of the track.
It should lie flush, with the lip hugging the back
edge of the track, as shown in Figure 1.
If your door track will not support the bracket
securely, walt installation is recommended.
Wall installation:
• Place the bracket against the walt with curved arms
facing the door. Be sure there is enough clearance
for the sensor beam to be unobstructed.
• If additional depth is needed, an extension bracket
(see Accessories) or wood blocks can be used.
• Use bracket mounting holes as a template to locate
and drill (2) 3/16" diameter pilot holes on the walt at
each side of the door, no higher than 6" (15 cm)
above the floor.
• Attach brackets to wall with lag screws
(not provided).
• If using extension brackets or wood blocks, adjust
fight and left assemblies to the same distance out
from the mounting surface. Make sure all door
hardware obstructions are cleared.
Floor installation:
• Use wood blocks or extension brackets (see
Accessories) to elevate sensor brackets so the
lenses wilt be no higher than 6" (15 cm) above the
floor.
• Carefully measure and place right and left
assemblies at the same distance out from the walt.
Be sure all door hardware obstructions are cleared.
• Fasten to the floor with concrete anchors as shown.

MOUNTING AND WIRING THE SAFETY SENSORS
• Slide a 1/4"-20xl/2" carriage bolt head into the slot
on each sensor. Use wing nuts to fasten sensors
to brackets, with lenses pointing toward each other
across the door. Be sure the lens is not obstructed
by a bracket extension. See Figure 4.
• Finger tighten the wing nuts.
Recommended Wire Routing
1.Using insulated staples, run the wires from both
sensors to the rail at the door header
(see Figure 5).
2. Cross and twist the two wires where they meet
the rail (see inset A). Run the wires inside the
channels at the top of the rail, along each side,
to the motor unit. De not use the lower (trolley)
channels. Use a screwdriver tip to tuck the wires
snugly into the channels.
NOTE: If your access door is near the garage
door, you may choose to install the door control at
this time and run the door control wire along the
raft with the sensor wires. Use one raft channel for
the door control wire and the other channel for
both sensor wires. If you choose this option, follow
instructions 1-3 on page 21 now.
3. Pull wires taut across the top of the chassis and
insert into the opening above the terminal block
(see Figure 5, Illustration B). You will complete the
wiring in installation Step 7.

INSTALLATION STEP 5
Position the Opener
Follow instructions which apply to your door type as
illustrated.
SECTIONAL DOOR OR ONE-PIECE DOOR WITH
TRACK
A 2x4 laid flat is convenient for setting an ideal door-
to-rail distance.
• Raise the opener onto a stepladder. You will need
help at this point if the ladder is not tall enough.
• Open the door all the way and place a 2x4 laid flat
on the top section beneath the rail.
• If the top section or panel hits the trolley when you
raise the door, pull down on the trolley release arm
to disconnect inner and outer sections. Slide the
outer trolley toward the motor unit. The trolley can
remain disconnected until Installation Step 13
is completed.

ONE-PIECE DOOR WITHOUT TRACK
• With the door fully open and parallel to the floor,
measure the distance from the floor to the top of
the door.
• Using a stepladder as a support, raise the top of
the opener to this height.
• The top of the door should be level with the top of
the motor unit. Do not position the opener more
than 3" (7.5 cm) above this point.

INSTALLATION STEP 6
Hang the Opener
Three 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).
Existing brackets from a previous installation may be
fastened to the sides of the motor unit as in
Figures 1 and 2, or to the mounting tabs as shown in
Figure 3. Then continue with step 5 below.
1. Remove foam packaging. 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"-18xl-7/8" lag screws.
5. Fasten the opener to the hanging brackets with
5/16"-18x7/8" hex bolts, lock washers and nuts.
If you wish to utilize the two center mounting tabs,
you must triangulate the vertical brackets for
additional stability. See Figure 3.
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.
Toavoid possible SERIOUSINJURYfrom a falling
garagedoor opener,fasten it SECURELYto structural
supports of the garage.Concreteanchors MUST be used
if installing any brackets into masonry.
