Installation Step 1
Determine Header Bracket Location
WARNING
If the header bracket is not rigidly fastened to a
structural support on the header wall or ceiling, the
safety reverse system may not work properly (see page
26). The door might not reverse when required, and
could cause serious injury or death.
Installation procedures vary according to garage
door types. Follow the instructions which apply to
your door.
The garage door springs, cables, pulleys, brackets and
their hardware are under extreme tension. Do not attempt
to loosen, move or adjust them yourself. Serious
personal injury or death could result. Call for
professional garage door service.

The Protector System®
IMPORTANT INFORMATION ABOUT THE
SAFETY REVERSING SENSOR
WARNING
The safety reversing sensor must be connected and
aligned correctly before the garage door opener will
move in the down direction. This is a required safety
device and cannot be disabled.
Without a properly working safety reversing sensor,
persons (particularly children) could be injured or killed
by a closing garage door. Read and follow all
instructions.
To protect small children, install the safety reversing
sensor so that the beam will be no higher than 4"-6"
above the garage floor.
When properly connected and aligned, the safety
reversing 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 light will flash for 5 seconds.
Disconnect power to the garage door opener before
installing the safety reversing sensor.
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 units must be installed inside the garage so that the
sending and receiving eyes face each other across the
door, between 4-6" 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 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.
The mounting brackets are designed to clip onto the
garage door track without additional hardware.

Electrical Requirements
WARNING
To prevent electrocution or fire, installation and wiring
must be in compliance with local electrical and building
codes.
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.
Do NOT use an extension cord, 2-wire adapter, or change
the plug in any way to make it fit your outlet.
If the plug doesn't fit into the outlet you have, contact a
qualified electrician to install the proper outlet.
To avoid installation difficulties,
do not run the opener until Step 9 below.
If permanent wiring is required by your local code,
refer to the following procedure:

WARNING
Fasten Door Bracket
To prevent damage to steel, aluminum, fiberglass or
glass panel doors, always reinforce the inside of the door
both vertically and horizontally with an angle iron.
Follow instructions which apply to your door type
as illustrated below or on page 21.
A horizontal brace should be long enough to be secured to 2 vertical supports. A vertical brace should cover the
height of the top panel.
The illustration shows one piece of angle iron as the horizontal brace. For the vertical brace, 2 pieces of angle iron
are used to create a U-shaped support. The best solution is to check with your garage door manufacturer for an
opener installation door reinforcement kit.

Adjustment Section: Pages 24 – 26
Adjustment Step 1
Adjust the UP and DOWN Limits
Do not make any limit adjustments until the safety
reversing sensors are completely installed.
WARNING
Improper adjustment of the travel limits will interfere with
the proper operation of the safety reverse system. The
door might not reverse properly when required and could
seriously injure or kill someone under it. Test the safety
reverse system monthly, and following all adjustments to
the travel limits. See page 26.
Limit adjustment settings regulate the points at which the
door will stop when moving up or down.
The door will stop in the up direction if anything
interferes with door travel. The door will reverse in the
down direction if anything interferes with the door travel
(including binding or unbalanced doors).
To operate the opener, press the Door Control push bar or

Adjustment Step 2. Use a screwdriver to make limit
adjustments.
How and When to Adjust the Limits
If the door does not open completely but opens at least
five feet:
If the opener reverses in fully closed position:
Decrease down travel. Turn the DOWN limit adjustment
screw clockwise. One turn equals 2" of travel.
Increase up travel. Turn the UP limit adjustment screw
clockwise. One turn equals 2" of travel.
If the door reverses when closing and there is no
visible interference to travel cycle:
If door does not open at least 5 feet: Adjust the UP
(open) force as explained in Adjustment Step 2.
If the opener lights are flashing, the Safety Reversing
Sensors are either not installed, misaligned, or obstructed.
See Troubleshooting, page 18.
If the door does not close completely:
Increase down travel. Turn the DOWN limit adjustment
screw counterclockwise. One turn equals 2" of travel.
Test the door for binding: Pull the manual release handle.
Manually open and close the door. If the door is binding,
call for garage door service. If the door is not binding or
unbalanced, adjust the DOWN (close) force. See
Adjustment Step 2.
If door still won't close completely, try lengthening the
door arm. (Page 22.)
If you have adjusted the door arm to the maximum length
and the door still will not close completely, lower the
header bracket. See Installation Step 1, pages 8/9.

Adjustment Step 2
Adjust the Force
WARNING
Too much force on the door will interfere with the proper
operation of the safety reverse system. The door might
not reverse properly when required and could seriously
injure or kill someone under it. Do not increase the force
beyond the minimum amount required to close the door.
Do not use the force adjustments to compensate for a
binding or sticking garage door. Test the safety reverse
system monthly, and following all adjustments to force
levels. See page 26.
Force adjustment controls are located on the right panel
of the opener. Force adjustment settings regulate the
amount of power required to open and close the door.
The door will stop in the up direction if anything
interferes with its travel. The door will reverse in the
down direction if anything interferes with its travel
(including binding or unbalanced doors).
If the forces are set too light, door travel may be
interrupted by nuisance reversals in the down direction
and stops in the up direction. Weather conditions can
affect the door movement, so occasional adjustment may
be needed.
The maximum force adjustment range is about 3/4 of a
complete turn. Do not force controls beyond that point.

How and When to Adjust the Forces
Test the DOWN (close) force
If the door doesn't open at least 5 feet:
Grasp the door bottom when the door is about halfway
through DOWN (close) travel. The door should reverse.
Reversal halfway through down travel does not
guarantee reversal on a one-inch obstruction. See
page 26. If the door is hard to hold or doesn't reverse,
decrease the DOWN (close) force by turning the control
counterclockwise.
Increase UP (Open) force by turning the control
clockwise. Make small adjustments until door opens
completely. Readjust the UP limit if necessary. After each
adjustment, run the opener through a complete travel
cycle.
If the door reverses during the down (close) cycle and
the opener lights aren't flashing:
Make small adjustments until the door reverses normally.
After each adjustment, run the opener through a complete
cycle.
Increase DOWN (close) force by turning the control
clockwise. Make small adjustments until the door
completes a close cycle. After each adjustment, run the
opener through a complete travel cycle. Do not increase
the force beyond the minimum amount required to
close the door.
Test the UP (open) force
Grasp the door bottom when the door is about halfway
through UP (open) travel. The door should stop. If the
door is hard to hold or doesn't stop, decrease UP (open)
force by turning the control counterclockwise.
Make small adjustments until the door stops easily. After
each adjustment, run the opener through a complete travel
cycle.

3. Does the battery test light glow when the remote control push button is pressed? If not,
replace the battery.
4. Program the receiver to match the remote control code.
5. Repeat the receiver programming procedure with all remote controls.
1. Check the battery test light. If the light is dim, replace the battery.
2. Change the location of the remote control in your car.
The remote control has
short range:
3. Check to be sure the antenna on the right side panel of opener extends fully.
4. Some installations may have shorter range due to a metal door, foil backed insulation, or
metal garage siding.
Opener noise is
disturbing in living
quarters of home:
If operational noise is a problem because of proximity of the opener to the living quarters, the
Vibration Isolator Kit 41A3263 can be installed. This kit was designed to minimize vibration
to the house and is easy to install.
The garage door
opens and closes by
itself:
1. Be sure that all remote control push buttons and battery indicator lights are off.
2. Remove the bell wire from the door control terminals and operate from the remote control
only. If this solves the problem, the door control is faulty (replace), or there is an
intermittent short on the wire between the door control and the opener.
The door doesn't open
completely:
1. If the door has been working properly but now doesn't open all the way, increase the up
force. See page 25.
2. Is something obstructing the door? Remove the obstruction or repair the door.
3. If door opens at least 5 feet, the travel limits may need to be increased. One turn equals
2 inches of travel. See page 24.
Repeat the safety reverse test after the adjustment is complete.
The door stops but
doesn't close
completely:
Review the travel limits adjustment procedures on page 24.
Repeat the safety reverse test after any adjustment of door arm length, close force or down
limit.
