An unbalanced garage door might not reverse
when required and someone under the door
could be seriously injured or killed.
If your garage door binds, sticks or is out of
balance, call for professional garage door
service. Garage doors, door springs, cables,
pulleys, brackets and their hardware are under
extreme tension and can cause serious injury
or death. Do not try to loosen, move or adjust
them yourself!
Ropes left on a garage door could cause
someone to become entangled and killed.
Remove all ropes connected to the door before
installing and operating the opener.
Identify the type and height of your door and any
special conditions that exist and any additional
materials that may be required by referring to the lists
on page 4 or page 5.
ts Screwdriver
To avoid damage to the garage door and
opener, disable locks before installing and
operating the opener. Use a wood screw or nail
to hold locks in the "open" (unlocked)
position.
Operation at other than 120V 60 Hz will cause
opener malfunction and damage.
Before you begin, complete the following test to
make sure your door is balanced, and is not
sticking or binding:
* Lift the door about halfway as shown. Release the
door. Itshould stay in place, supported entirely by
its springs.
* Raise and lower the door to see if there is any
binding or sticking.

IMPORTANT INSTALLATION INSTRUCTIONS
To reduce the risk of severe injury or death to persons:
1. READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS.
2. install only on a properly balanced and lubricated garage door. An improperly balanced door
may not reverse and could result in severe injury or death. Repairs to cables, spring assemblies
and other hardware must be made by a professional service person before installing opener.
3. Disable all locks and remove all ropes connected to the garage door before installing the opener.
Ropes connected to a garage door can cause entanglement and death.
4. if possible, install door opener 7 feet or more above floor with the emergency release handle
mounted 6 feet above the floor.
5. Do not connect the opener to power source until instructed to do so.
6. Locate the Door Control within sight of the door at a minimum height of 5 feet where small
children cannot reach and away from all moving parts of the door.
7. install the User Safety Instruction Label on the wall adjacent to the door control and the
Maintenance Instruction Label in a prominent location on the inside of the garage door.
8. Upon completion of the installation, the door must reverse when it comes in contact with a
one-inch high object or a 2×4 laid flat on the floor.
9. Do not wear watches, rings or loose clothing while installing or servicing an opener. Jewelry or
loose clothing can be caught in the mechanism of the garage door or the opener.

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 30). The door might
not reverse when required, and could cause
serious injury or death.
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.
• Close the door and mark the inside
vertical centerline of the garage door.
• Extend the line onto the header wall
above the door.
Remember, you can fasten the
header bracket within 2 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 (refer to 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 supplied) to securely fasten
the 2x4 to structural supports as shown
here and on page 13.
• Open your door to the highest
point of travel as shown. Draw
an intersecting horizontal line
on the header wall 2" above
the high point. This height will
provide travel clearance for the
top edge of the door.
Door clearance brackets are
available for sectional doors
when headroom clearance is
less than 2". See accessory
page 38.

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. The bracket and fastening hardware are not
supplied. See accessory page 38.
Measure the distance from each side of the opener
to the structural support.
• Cut both pieces of the hanging bracket to required
lengths.
• Drill 3/16" pilot holes in the structural supports.
• Attach one end of each bracket to a support with
5/16"xl 8-1-7/8" lag screws.
• Fasten the opener to the hanging brackets with
5/16"-18x7/8" screws, lock washers and nuts.
• Check to make sure the T-rail is centered over the
door (or in line with the header bracket if the
bracket is not centered above the door).
• Remove the 2x4. Operate the door manually. If the
door hits the rail, raise the header bracket.

Install the Premium Control Console
Locate the door control within sight of the door
at a minimum height of 5 feet where small
children cannot reach, and away from all moving
parts of the door and door hardware.
The door control is typically attached directly to the
wall. If installing into drywall, drill 5/32" holes and
use the anchors _rovided. Forpre-wired installations
(as in new home construction), Console models
may be mounted to a standard single gang box
(Figure 2).
1. Strip 1/4" of insulation from one end of the bell
wire and connect it to the two screw terminals on
the back of the door control: white to 2, and
white/red to 1.
2. Pry off cover along one side with a screwdriver
blade (see Figure 1). Fasten with 6ABx1-1/4" self-
tapping screws (standard installation) or 6-32x1"
machine screws (pre-wired installation) as follows:
• Install bottom screw, allowing 1/8" 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 overtighten.
• Insert top tabs and snap on cover.
3. (For standard installation) Run the bell wire up the
wall and across the ceiling to the opener. Use
insulated staples to secure the wire in several
places. Be careful not to pierce the wire with a
staple, creating a short.
4. Connect the bell wire to the terminal screws on
the opener panel: white to 2; white/red to 1.
5. Position the antenna wire as shown.
Do not connect to live electrical wiring. Connect
only to 24 Volt low voltage wires. Connection to
live wires or higher voltage may cause serious
injury from shock, burn or electrocution.
Children operating or playing with a garage
door opener can injure themselves or others.
The garage door could close and cause
serious injury or death.
install the door control (or any additional push
buttons) out of the reach of children and away
from all moving parts of the door and door
hardware, but where the garage door is visible.
Do not allow children to operate the push
button(s) or the remote control(s).
A moving garage door could injure someone
under it. Activate the opener only when the
door is properly adjusted, you can see it
clearly, and there are no obstructions to door
travel.

Instafl the Lights and the Lenses
Install the lights:
• Install a 75 watt maximum light bulb in each
socket. The lights will turn ON and remain lit for
approximately 4-1/2 minutes when power is
connected. Then the lights will turn OFF.
• If the bulbs burn out prematurely due to vibration,
replace them with standard neck "Garage Door
Opener" bulbs.
Do NOT connect the power and operate the
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.
See Safety Reversing Sensor instructions
beginning on page 21.

Electrical Requirements
To prevent electrocution or fire, installation
and wiring must be in compliance with local
To reduce the risk of electric shock, your garage
door opener has a grounding type plug with a third
grounding pin. This plug will onlyfit 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.
To avoid installation difficulties,
do not run the opener at this time.
if permanent wiring is required by your local code, refer to the following procedure:
electrical and building codes.
Do NOT use an extension cord, 2-wire adapter,
or change the plug in any way to make it fit
your outlet.
Right Wrong
To make a permanent connection through the
7/8" diameter hole in the top of the opener
(according to local code):
* Remove the opener 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.

The Safety Reversing System
Information you'll need before you begin the installation of 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. This is a
required safety device and cannot be disabled.
Installation procedures are the same for sectional
and one-piece doors.
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.
Disconnect power to the garage door opener
before installing the safety reversing sensor.
Be sure power to the opener is disconnected.
The sending eye transmits an invisible light beam to
the receiving eye. The units can be installed on
either side of the garage door as long as the sun
never shines directly into the receiving eye lens.
Look at the label on the connector end of each case
to identify the sensors.
The brackets must be connected and fastened so
that the sending and receiving eyes face each other
as shown in Figure 1.
If an obstruction breaks the light beam while the
garage door is closing, the door will stop and
reverse to full open position and the opener lights
will flash for 5 seconds.
The brackets must be securely fastened to a solid
surface such as the studs on either side of the door,
or add a piece of wood at each location if installing in
masonry construction,
The invisible light beam path must be unobstructed,
No part of the garage door (or door tracks, springs,
hinges, rollers or other hardware) can interrupt the
beam while the door is closing, If it does, use a piece
of wood to build out each sensor mounting location to
the minimum depth required for light beam clearance,

Figures 2 and 3 show assembly of brackets and
"C" wrap based on the recommended installation of
the sensors as shown on page 21.
However, Figures 4 and 5 are variations which may
fit your installation requirements better. Make sure
the wraps and brackets are aligned so the
sensors will face each other across the garage
door.
, Fasten the "C" wraps to the mounting brackets
having square holes, using the hardware shown
in Figure 2.
• Connect each assembly to a slotted bracket, using
the hardware shown in Figure 3.
Note the alignment of the brackets for left and
right sides of the door.
• Finger tighten the lock nuts.
• Use bracket mounting holes as a template to
locate and drill (2) 3/16" diameter pilot holes on
both sides of the garage door, 4"-6" above the
floor but not exceeding 6". (See warning on
page 21 .)
• Attach bracket assemblies with 1/4"x1-1/2" lag
screws as shown in Figure 3.
• Adjust right and left side bracket assemblies to the
same distance out from the mounting surface.
Make sure all door hardware obstructions are
cleared. Tighten the nuts securely.

Secure sensors with the hardware shown. Finger
tighten the wing nut on the receiving eye to allow
for final adjustment. Securely tighten the sending
eye wing nut.
, Run the wires from both sensors to the opener.
Use insulated staples to secure wire to wall and
ceiling.
Strip 1/4" of insulation from each set of wires.
Separate white and white/black wires sufficiently to
connect to the opener terminal screws: white to 2
and white/black to 3.
Aligning the Safety Sensors
• Plug in the opener. Green indicator lights in both
the sending and receiving eyes will glow steadily if
wiring connections and alignment are correct.
The sending eye indicator light will glow regardless
of alignment or obstruction. If the indicator light is
off, dim, or flickering in the receiving eye (and the
invisible light beam path is not obstructed),
alignment is required.
Loosen the sending eye wing nut and re-adjust,
aiming directly at the receiving eye. Lock in place.
Loosen the receiving eye wing nut and adjust
sensor vertically and/or horizontally until it receives
the sender's beam. When the green indicator light
glows steadily, tighten the wing nut.

Closed Door Adjustment:
Decrease DOWN limit
o
Turn the DOWN limit adjustment screw clockwise
5 complete turns.
o
Press the Wall Control push bar. The trolley will
travel to the fully closed position.
o
Manually close the door and lift the door arm to the
trolley. The arm should touch the trolley just ahead
of the door arm connector hole. Refer to the fully
closed trolley/door arm positions in the illustration. If
the arm is behind the connector hole, adjust the limit
further. One full turn equals 2" of trolley travel.
Connect the door arm to the trolley.
, Close the door and join the curved arm to the connector hole in the trolley with the remaining clevis pin. It may
be necessary to lift the door slightly to make the connection.
* Secure with a ring fastener.
Run the opener through a complete travel cycle. If the door has a slight "backward" slant in full open position
as shown in the illustration, decrease the UP limit until the door is parallel to the floor.
27
Page 28

Adjustment Section: Pages 28 - 30
Adjustment Step 1
Adjust the UP and DOWN Limits
Do not make any limit adjustments until the
safety reversing sensors are completely
installed.
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
button. Run the opener through a complete travel
cycle.
• Does the door open and close completely?
• Does the door stay closed and not reverse
unintentionally when fully closed?
If your door passes both of these tests, no limit
adjustments are necessary unless the reversing test
fails (See page 30).
Adjustment procedures are outlined below. Run
the opener through a complete travel cycle after
each adjustment.
Repeated operation of the opener during
adjustment procedures may cause the motor to
overheat and shut off. Simply wait 15 minutes
and try again.
Read the procedures carefully before proceeding to
Adjustment Step 2. Use a screwdriver to make limit
adjustments.
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 following all
adjustments to the travel limits. See page 30.

How and When to Adjust the Limits
, if the door does not open completely, but
opens at least five feet:
Increase up travel. Turn the UP limit adjustment
screw clockwise. One turn equals 2" of travel.
NOTE: To prevent the trolley from hitting the
cover protection bolt, keep a minimum distance
of 2-4" between the trolley and the bolt.
* if door does not open at least 5 feet:
Adjust the UP (open) force as explained in
Adjustment Step 2.
, If the door does not close completely:
Increase down travel. Turn the DOWN limit
adjustment screw counterclockwise. One turn
equals 2" of travel.
If the door still won't close completely and the trolley
bumps into the pulley bracket (see page 4 or 5), try
lengthening the door arm (see page 26).
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 12 and 13.
if the opener reverses in fully closed position:
Decrease down travel. Turn the DOWN 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 the opener lights are flashing, the Safety Reversing
Sensors are either not installed, misaligned, or
obstructed. See Troubleshooting, page 23.
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.
28
Page 29

Adjustment Step 2 I
Adjust the Force
Force adjustment controls are located on the right
side 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 260 degrees,
about 3/4 of a complete turn. Do not force controls
beyond that point. Turn force adjustment controls
with a screwdriver.
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 following all adjustments to force
levels. See page 30.

How and When to Adjust the Forces
Test the DOWN (close) force
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 two-inch
obstruction. See page 30. If the door is hard to
hold or doesn't reverse, decrease the DOWN (close)
force by turning the control counterclockwise.
Make 10 degree turn adjustments until the door
reverses normally. After each adjustment, run the
opener through a complete cycle.
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.
Right Side Panel
Make 10 degree turn adjustments until the door stops
easily. After each adjustment, run the opener through
a complete travel cycle.
If the door doesn't open at least 5 feet
Increase UP (Open) force by turning the control
clockwise. Make 10 degree turn adjustments until
door opens completely. Re-adjust 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
Increase DOWN (close) force by turning the control
clockwise. Make 10 degree turn 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.

Adjustment Step 4
Test the Safety Reverse System
Failure to test and adjust the safety reverse
system may result in serious injury or death to
persons trapped by a closing garage door.
Repeat this test once a month and adjust as
needed.
Test:
* Place a one-inch board (or a 2x4 laid flat) on the
floor, centered under the garage door.
, Operate the door in the down direction. The door
must reverse on striking the obstruction.
Adjustment:
If the door stops on the obstruction, it is not traveling
far enough in the down direction.
• Increase the DOWN limit by turning the DOWN
limit adjustment screw counterclockwise 1/4 turn.
• Repeat the test.
On a sectional door, make sure limit
adjustments do not force the door arm beyond a
straight up and down position. See the
illustration on page 26.
• When the door reverses on the one-inch board,
remove the obstruction and run the opener through
3 or 4 complete travel cycles to test adjustment.
if the door will not reverse after repeated
adjustment attempts, call for professional
garage door service.
