Preparing your garage door
WARNING
Before you begin:
To prevent possible SERIOUS INJURY or DEATH:
• Disable locks.
• 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.
• 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.
CAUTION
To prevent damage to garage door and opener:
• ALWAYS disable locks BEFORE installing and operating
the opener.
• ONLY operate garage door opener at 120V, 60 Hz to
avoid malfunction and damage.

Planning
Identify the type and height of your garage door.
Survey your garage area to see if any of the
conditions below apply to your installation. Additional
materials may be required. You may find it helpful to
refer back to this page and the accompanying
illustrations as you proceed with the installation of
your opener.
• Do you have an access door in addition to the
garage door? If not, Model 7702CB Emergency
Key Release is required. See Accessories page.
• Look at the garage door where it meets the floor.
Any gap between the floor 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.
Depending on your requirements, there are several
installation steps which may call for materials or
hardware not included in the carton.
• Installation Step 1 – Look at the wall or ceiling
above the garage door. The header bracket must
be securely fastened to structural supports.
SECTIONAL DOOR INSTALLATIONS
• Do you have a steel, aluminum, fiberglass or glass
panel door? If so, horizontal and vertical
reinforcement is required (Installation Step 11).
• Installation Step 5 – Do you have a finished ceiling
in your garage? If so, a support bracket and
additional fastening hardware may be required.
• 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 (1.21 m) to the left or
right of the door center. See Installation Steps 1
and 11.
• Installation Step 10 – Depending upon garage
construction, extension brackets or wood blocks
may be needed to install sensors.
• Installation Step 10 – Alternate floor mounting of
the safety reversing sensor will require hardware
not provided.
• If your door is more than 7 feet (2.12 m) high, see
rail extension kits listed on Accessories page.

Electrical Requirements
To prevent possible SERIOUS INJURY or DEATH from
electrocution or fire:
To avoid installation difficulties, do not run the
opener at this time.
• 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 fit outlet. Be sure
the opener is grounded.
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 fit into the outlet you
have, contact a qualified electrician to install the
proper outlet.

INSTALLATION STEP 10
WARNING
®
Install The Protector System
Be sure power is not connected to the garage door
opener BEFORE installing 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.
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.
IMPORTANT INFORMATION ABOUT
THE SAFETY REVERSING SENSOR
• Install the safety reversing sensor so beam is NO
HIGHER than 6" (15 cm) above garage floor.
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 flash 10 times.
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, 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 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
track of sectional garage doors without additional
hardware.

MOUNTING AND WIRING THE SAFETY SENSORS
Figure 5
• Slide a 1/4"-20x1/2" carriage bolt head into the 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 5).

• Run the wires from both sensors to the opener. Use
insulated staples to secure wire to wall and ceiling.
TROUBLESHOOTING THE SAFETY SENSORS
• Strip 7/16" (11 mm) of insulation from each set of
wires. Separate white and white/black wires
sufficiently to connect to the opener quick-connect
terminals. Twist like colored wires together. Insert
wires into quick-connect holes: white to white and
white/black to grey (Figure 6).
1. If the sending eye indicator light does not glow
steadily after installation, check for:
• Electric power to the opener.
• A short in the white or white/black wires. These
can occur at staples, or at opener connections.
• Incorrect wiring between sensors and opener.
• A broken wire.
ALIGNING THE SAFETY SENSORS
• Plug in the opener. The indicator lights in both the
sending and receiving eyes will glow steadily if
wiring connections and alignment are correct.
2. If the sending eye indicator light glows steadily but
the receiving eye indicator light doesn't:
• Check alignment.
The sending eye amber indicator light will glow
regardless of alignment or obstruction. If the green
indicator light in the receiving eye is off, dim, or
flickering (and the invisible light beam path is not
obstructed), alignment is required.
• Check for an open wire to the receiving eye.
3. If the receiving eye indicator light is dim, realign
either sensor.
NOTE: When the invisible beam path is obstructed
or misaligned while the door is closing, the door will
reverse. If the door is already open, it will not close.
The opener lights will blink 10 times. See page 20.
• Loosen the sending eye wing nut and readjust,
aiming directly at the receiving eye. Lock in place.
• Loosen the receiving eye wing nut and adjust
sensor until it receives the sender’s beam. When
the green indicator light glows steadily, tighten the
wing nut.

seconds, indicates batteries are low.
• Once the power is restored the BBU will recharge.
This is indicated by a flashing green LED.
RED LED:
After the electrical power has been restored, the
batteries will recharge within 48 hours. Under normal
usage batteries will last 3 to 5 years.
An error has been detected and the BBU will
automatically shut off. The BBU will attempt to restart
by reconnecting to the batteries. If the error is still
present it will shut itself off again. This process will
repeat every 5 minutes or until the error has been
resolved. This is used to prevent further draining of
the batteries.
To obtain maximum battery life and prevent damage,
also disconnect the battery backup if you unplug the
motor unit while on vacation or any other extended
period of time.
• If a red LED remains on when the power is
restored, and is accompanied by a beep sounding
every 30 seconds, please call for service.

WHICH ARE LIMITED IN DURATION TO THE BELT 10 YEARS AND MOTOR LIFETIME LIMITED WARRANTY PERIOD FOR THE

MAINTENANCE, UNAUTHORIZED REPAIRS OR ANY ALTERATIONS TO THIS PRODUCT), LABOR CHARGES FOR
