STEP 1 Determine the header bracket location

To prevent possible SERIOUS INJURY or DEATH:

l Header bracket MUST be RIGIDLY fastened to structural support on header wall or ceiling,

otherwise garage door might NOT reverse when required. DO NOT install header bracket over
drywall.

l Concrete anchors MUST be used if mounting header bracketor 2x4 into masonry.
l NEVER tryto loosen, move or adjust garage door, springs, cables,pulleys, brackets, or their

hardware, ALL of which are under EXTREME tension.

l ALWAYS call a trained door systems technician if garage door binds, sticks, or is out of balance.

An unbalanced garage door might NOT reverse when required.

Installation procedures vary according to garage door types.Follow the instructions which apply to your
door.

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 (1.22 m) 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 12) when clearance is minimal. (Itmay be
mounted on the wall upside down if necessary,to gain approximately1/2" (1 cm).Ifyou 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 supportsas shown here and on page 12.

3. Open your door to the highest point of travel as shown. Draw an intersecting horizontal line on
the header wall 2" (5 cm) above the high point :

l 2" (5 cm) above the high point for sectional door and one-piece door with track.
l 8" (20 cm) above the high point for one-piece door without track.

This height will provide travel clearance for the top edge of the door. NOTE: If the total number of inches
exceeds the height available in your garage, use the maximum height possible, or refer to page 12 for
ceiling installation.

®

Be sure power is NOT connected to the garage door opener BEFORE installing the safetyreversing
sensor.

To prevent SERIOUS INJURY or DEATH from closing garage door:

l Correctlyconnect and align the safetyreversing sensor. This required safetydevice MUST NOT

be disabled.

l Install the safety reversing sensor so beam is NO HIGHERthan 6" (15 cm) above garage floor.

The safety reversingsensors must be connected and aligned correctly before the garage door
openerwillmove inthe down direction.
IMPORTANT INFORMATION ABOUTTHE SAFETY REVERSING SENSORS

When properly connected and aligned, the sensor will detectan obstacle in the path of itselectronic
beam. The sending eye (with an amber indicator light) transmitsan 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 acrossthe 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 directlyinto the receiving eye lens. The mounting bracketsare designed to clip onto the
trackof sectional garage doors without additional hardware.

Ifit 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 mustbe 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.

Facingthe door from inside the garage

The safety reversing sensors can be attached to the door track,the wall, or the floor. The sensors should
be no more than 6 inches (15 cm) above the floor. If the door trackwill not support the sensor bracketa
wall installation is recommended. Choose one of the following installations.

OPTION A DOOR TRACK INSTALLATION

1. Slide the curved arms of the sensor bracket around the edge of the door track.Snap into place
so that the sensor bracket is flush against the track.

2. Slide the carriage bolt into the slot on each sensor.

3. Insert the bolt through the hole in the sensor bracket and attach with the wing nut. The lenses on
both sensors should point toward each other. Make sure the lens is not obstructed by the sensor
bracket.

STEP 15 Connect power

To prevent possible SERIOUS INJURY or DEATH from electrocution or fire:

l Be sure power is NOT connected to the opener, and disconnect power to circuit BEFORE

removing cover to establish permanent wiring connection.

l Garage door installation and wiring MUSTbe in compliance with ALL local electrical and

building codes.

l NEVER use an extension cord, 2-wire adapter, or change plug in ANY way to make it fit outlet. Be

sure the opener is grounded.

To avoid installationdifficulties,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 fitinto the outlet you
have, contact a qualified electrician to install the proper outlet.

THERE ARE TWO OPTIONS FOR CONNECTING POWER:

OPTION A TYPICAL WIRING

1. Plug in the garage door opener into a grounded outlet.

2. DO NOT run garage door opener at this time.

OPTION B PERMANENT WIRING

If permanent wiring is required by your local code,refer to the followingprocedure. To make a
permanent connection through the 7/8 inch hole in the top of the motorunit (according to local
code):

1. Remove the motor unit cover screwsand set the cover aside.

2. Remove the attached 3-prong cord.

3. Connectthe black (line) wire to the screwon the brass terminal; the white (neutral) wire to the
screwon the silver terminal; and the ground wire to the green ground screw.The openermust

be grounded.

Without a properly installed safety reversal system, persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage door.

l Incorrectadjustmentof garage door travel limitswill interfere with proper operation of safety

reversal system.

l After ANY adjustments are made, the safetyreversal system MUST be tested. Door MUST reverse

on contactwith 1-1/2" (3.8 cm) high object (or 2x4 laid flat) on floor.

To prevent damage to vehicles,be sure fully open door provides adequate clearance.

Limit adjustment settings regulate the points at which the door will stop when moving up or down.
To operate the opener, pressthe Door Control push bar.

Runthe opener through a complete travel cycle.

• Does the door open and close completely?

• Does the door stayclosed and not reverse unintentionally when fully closed?
Ifyour door passesboth of these tests, no limit adjustmentsare necessary unless the reversing test fails

(Adjustment Step 3, page 30).
Adjustmentprocedures are outlined below.Read the procedures carefully before proceeding to

AdjustmentStep 2. Use a screwdriver to make limit adjustments.
Run the opener through a complete travel cycle after each adjustment.

NOTE: Repeated operation of the opener during adjustment procedures may cause the motor to
overheat and shut off.Simply wait 15 minutes and try again.

NOTE: Anything interferes with the door’s upward travel, it will stop. If anything interferes with the door’s
downward travel (including binding or unbalanced doors), it will reverse.

HOW AND WHEN TO ADJUST THE LIMITS

• If the doordoes not open completely but opens at least five feet (1.5 m):

Increase up travel. Turn the UP limit adjustment screw clockwise.One turn equals 2" (5 cm) of travel.

NOTE: To prevent the trolley from hitting the cover protection bolt, keep a minimum distance of 2-4"
(5 cm - 10 cm) between the trolley and the bolt.

• If doordoes not open at least 5 feet (1.5 m):

Adjust the UP (open) force as explained in Adjustment Step 2.

• If the doordoes not close completely:

Increase down travel. Turn the DOWN limit adjustmentscrewcounterclockwise.One turn equals 2"
(5 cm) of travel.

Ifdoor still won’t close completely and the trolley bumps into the pulley bracket, try lengthening the
door arm (page 18) and decreasing the down limit.

• If the opener reverses in fully closedposition:

Decrease down travel. Turn the DOWNlimit adjustmentscrewclockwise. One turn equals 2" (5 cm)
of travel.

• If the doorreverses when closingand there is no visible interference to travel cycle:

Ifthe opener lights are flashing, the Safety Reversing Sensors are either not installed, misaligned, or
obstructed. See page 27.

Testthe door for binding: Pull the emergency release handle. Manually open and close the door. If
the door is binding or unbalanced, call for a trained door systems technician. If the door is balanced
and not binding, adjust the DOWN (close) force. See Adjustment Step 2.

STEP 2 Adjust the Force

Without a properly installed safety reversal system, persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage door.

l Too much force on garage door will interfere with proper operation of safetyreversal system.
l NEVER increase force beyond minimum amount required to close garage door.
l NEVER use force adjustmentsto compensate for a binding or sticking garage door.
l Ifone control (force or travel limits)is adjusted, the other control may also need adjustment.
l After ANY adjustments are made, the safetyreversal system MUST be tested. Door MUST reverse

on contactwith 1-1/2" high (3.8 cm) object (or 2x4 laid flat) on floor.

Force adjustment controls are located on the right panel of the motor unit. Force adjustment settings
regulate the amount of power required to open and close the door.

Ifthe forcesare set too light, door travel may be interrupted by nuisance reversals in the down direction
and stops in the up direction. Weather conditions can affectthe door movement,so occasional
adjustmentmay be needed.

The maximum force adjustment range is about 3/4 of a complete turn.Do not force controls beyond

that point. Turn force adjustment controls with a screwdriver.

NOTE: If anything interferes with the door’s upward travel,it will stop. Ifanything interferes with the door’s

downward travel (including binding or unbalanced doors), it will reverse.

HOW AND WHEN TO ADJUST THE FORCE

1. Test the DOWN (close) force

l Grasp the door bottomwhen the door is about halfway through DOWN (close) travel. The door

should reverse. Reversal halfway through down travel does not guarantee reversal on a
1-1/2" (3.8 cm) obstruction.See AdjustmentStep 3, page 30. If the door is hard to hold or
doesn’t reverse, DECREASE the DOWN (close) force by turning the control counterclockwise.
Make small adjustmentsuntil the door reverses normally. After each adjustment,run the opener
through a complete cycle.

l If the doorreverses during the down(close) cycle and the opener lights aren’t flashing,

INCREASE DOWN (close) force by turning the control clockwise.Make small adjustmentsuntil
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.

2. Test the UP (open) force

l Grasp the door bottomwhen 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 adjustmentsuntil the door stops easily and opens fully.
After each adjustment, run the opener through a complete travel cycle.

l If the doordoesn’t openat least 5 feet (1.5 m), INCREASE UP (open) force by turning the

control clockwise.Make small adjustmentsuntil door opens completely.Readjustthe UP limit if
necessary.After each adjustment,run the opener through a complete travel cycle.

Without a properly installed safety reversal system, persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage door.

l Safetyreversal system MUST be tested every month.
l After ANY adjustments are made, the safetyreversal system MUST be tested. Door MUST reverse

on contactwith 1-1/2" (3.8 cm) high object (or 2x4 laid flat) on the floor.

1. With the door fully open, place a 1-1/2 inch (3.8 cm) board (or a 2x4 laid flat) on the floor,
centered under the garage door.

2. Operate the door in the down direction. The door MUST reverse on striking the obstruction.

Ifthe door stops and does not reverse on the obstruction,the down travel needs to be increased (refer to
AdjustmentStep 1). Repeat the test. When the door reverses upon contactwith the 1-1/2 inch board,
remove the board and open/close the door 3 or 4 timesto test the adjustment. If the garage door opener
continues to fail the safetyreversal test,call a trained door systems technician.

Without a properly installed safety reversing sensor, persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage door.

1. Press the remote control push button to open the door.

2. Place the opener carton in the path of the door.

3. Press the remote control push button to close the door. The door will not move more than an inch
