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 3" above the high point. This height
will provide travel clearance for the top edge of the
door.

INSTALLATION STEP 4
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 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 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" 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.
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.
• Be sure power is not connected to the garage door
opener BEFORE installing the safety reversing sensor.
• To prevent SERIOUS INJURY or DEATH from a closing
garage door:
– Correctly connect and align the safety reversing
sensor. This required safety device MUST NOT be
disabled.
– Install the safety reversing sensor so beam is NO
HIGHER than 6" above garage floor.

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" 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, wall installation is recommended.
Wall installation:
•Place the bracket against the wall 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 wall at each side of the door, no higher than 6"
above the floor.
•Attach brackets to wall with lag screws
(not provided).
•If using extension brackets or wood blocks, adjust
right 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 will be no higher than 6" above the floor.
•Carefully measure and place right and left
assemblies at the same distance out from the wall.
Be sure all door hardware obstructions are
cleared.
•Fasten to the floor with concrete anchors as
shown.

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 (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 (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. Do 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
rail with the sensor wires. Use one rail 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 inset B). You will complete the wiring in
Installation Step 7.

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" above this point.
INSTALLATION STEP 5
Position the Opener
Follow instructions which apply to your door type as
illustrated.
SECTIONAL DOOR OR ONE-PIECE DOOR WITH
TRACK
A2x4 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.

INSTALLATION STEP 6
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.
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"-18x1-7/8" 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 (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.
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.
