IMPORTANT SAFETY NOTES

TABLE OF CONTENTS

Before you begin:

• Disable locks (contact your door manufacturer for

information on disabling your door locks.)

• Remove any ropes connected to garage door.

• Complete the following test to make sure your garage

door is balanced and is not sticking or binding:

1. Lift the door about halfway as shown. Release the

door. If balanced, it should stay in place, supported

entirely by its springs.

2. Raise and lower the door to see if there is any

binding or sticking.

If your door binds, sticks, or is out of balance, call a

trained door systems technician.

If you have a one-piece door, the installation of your

garage door opener will be different. Follow the assembly

instructions included in this manual then proceed to the

• ALWAYS disable locks BEFORE installing and

operating the opener.

• ONLY operate garage door opener at 120V, 60 Hz

to avoid malfunction and damage.

To prevent possible SERIOUS INJURY or DEATH:

• ALWAYS call a trained door systems technician if

garage door binds, sticks, or is out of balance. An

unbalanced garage door may NOT reverse when

required.

• NEVER try to loosen, move or adjust garage door,

door springs, cables, pulleys, brackets or their

hardware, ALL of which are under EXTREME

tension.

• Disable ALL locks and remove ALL ropes connected

to garage door BEFORE installing and operating

garage door opener to avoid entanglement.

See Addendum

Planning

Identify the type and height of your garage door. If you

have a one-piece door, follow the assembly instructions

contained in this manual and refer to the Installation

Instructions One-Piece Door for installation procedures.

Survey your garage area to see if any of the conditions

below apply to your installation. Additional materials may

be required. You may ﬁ nd 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 Page 10 – Look at the wall or ceiling above

the garage door. The header bracket must be securely

fastened to structural supports.

• Installation Page 12 – Do you have a ﬁ nished ceiling

in your garage? If so, a support bracket and additional

fastening hardware may be required.

• Installation Page 13 – Do you have a steel, aluminum,

ﬁ berglass or glass panel door? If so, horizontal and

vertical reinforce ment is required.

• Installation Page 18 – Depending upon garage

construction, extension brackets or wood blocks may

be needed to install sensors.

• Installation Page 18 – Alternate ﬂ oor 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 7702CB Outside Quick Release is

required. See Accessories page.

• Look at the garage door where it meets the ﬂ oor. Any

gap between the ﬂ oor and the bottom of the door must

not exceed 1/4" (6 mm). Otherwise, the safety reversal

system may not work properly. See Adjustment Step 3.

Floor or door should be repaired.

• 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 (1.22 m) to the left or right of the door

center.

• If your door is more than 7 feet (2.13 m) high, see rail

extension kits listed on Accessories page 33.

Without a properly working safety reversal system,

persons (particularly small children) could be

SERIOUSLY INJURED or KILLED by a closing garage

door.

• The gap between the bottom of the garage door and

the ﬂ oor MUST NOT exceed 1/4" (6 mm). Otherwise,

the safety reversal system may NOT work properly.

• The ﬂ oor or the garage door MUST be repaired to

eliminate the gap.

If permanent wiring is required by your local code, follow procedure below. Disconnect power to the circuit

before removing cover to establish permanent wiring connections.

To prevent possible SERIOUS INJURY or DEATH from

electrocution or ﬁ re:

• Be sure power is NOT connected to the opener, and

disconnect power to circuit BEFORE removing cover

to establish permanent wiring connection.

• Garage door installation and wiring MUST be in

compliance with ALL local electrical and building

codes.

• NEVER use an extension cord, 2-wire adapter, or

change plug in ANY way to make it ﬁ t outlet. Be sure

the opener is grounded.

NOTE: Plug motor unit into grounded power outlet. If

a grounded outlet is not available, contact a qualiﬁ ed

electrician to install a proper outlet.

To prevent possible OVERHEATING of the endpanel or

light socket:

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" (15 cm) above garage ﬂ oor.

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.

NOTE: DO NOT operate the opener at this time.

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 amber 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 ﬂ ash 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 ﬂ oor. 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.

Protection Area

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.
