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.

• Do you have an access door in addition to the

garage door? If not, Model 7702CB Outside Quick

Release is required. See Accessories page.

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.

• 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". 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.

SECTIONAL DOOR INSTALLATIONS

• Installation Step 1 – Look at the wall or ceiling

above the garage door. The header bracket must

be securely fastened to structural supports.

• Do you have a steel, aluminum, fiberglass or glass

panel door? If so, horizontal and vertical reinforce-

ment 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 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.

• If your door is more than 7 feet high, see rail

extension kits listed on Accessories page.

• Installation Step 10 – Alternate floor mounting of

the safety reversing sensor will require hardware

not provided.

ONE-PIECE DOOR INSTALLATIONS

Without a properly working safety reversal system,

persons (particularly small children) could be

SERIOUSLY INJURED or KILLED by a closing garage

door.

• Generally, a one-piece door does not require

reinforcement. If your door is lightweight, refer to

the information relating to sectional doors in

Installation Step 11.

• The gap between the bottom of the garage door and

the floor MUST NOT exceed 1/4". Otherwise, the safety

reversal system may not work properly.

• The floor or the garage door MUST be repaired to

eliminate the gap.

• Depending on your door’s construction, you may

need additional mounting hardware for the door

bracket (Step 11).

Locate door control within sight of the door at a

minimum height of 5 feet where small children

cannot reach, and away from moving parts of the

door and door hardware. If installing into drywall

(Fig. 1), drill 5/32" holes and use anchors provided.

For pre-wired installations (as in new home

construction), it may be mounted to a single gang

box (Fig. 2). NOTE: After installation, a green

indicator light behind the cover will indicate proper

connection. If not lit, the Lock and Light features will

not function (reverse wires to correct).

• Be sure power is not connected before installing door

control.

• Connect only to 24 VOLT low voltage wires.

To prevent possible serious injury or death from a closing

garage door:

• Install door control within sight of garage door, out of

reach of children at a minimum height of 5 feet, and

away from all moving parts of door.

• Never permit children to operate or play with door

control push buttons or remote control transmitters.

• Activate door only when it can be seen clearly, is

properly adjusted, and there are no obstructions to door

travel.

• Always keep garage door in sight until completely

closed. Never permit anyone to cross path of closing

garage door.

WARNING

To prevent possible SERIOUS INJURY or DEATH from

electrocution or fire:

• 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.

Electrical Requirements

To avoid installation difficulties, 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 fit into the outlet you

have, contact a qualified electrician to install the

proper outlet.

INSTALLATION STEP 10

WARNING

• Be sure power is not connected to the garage door

opener BEFORE installing the safety reversing sensor.

• 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 Protector System

The safety reversing sensor must be connected

and aligned correctly before the garage door

opener will move in the down direction.

IMPORTANT INFORMATION ABOUT

THE SAFETY REVERSING SENSOR

– Install the safety reversing sensor so beam is NO

HIGHER than 6" 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 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 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" 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.

TROUBLESHOOTING THE SAFETY SENSORS

• 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. See Figure 5.

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 screw terminal

connections.

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.

• Incorrect wiring between sensors and opener.

• A broken wire.

The sending eye orange 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.

2. If the sending eye indicator light glows steadily but

the receiving eye indicator light doesn't:

• Check alignment.

• Check for an open wire to the receiving eye.

• Loosen the sending eye wing nut and readjust,

aiming directly at the receiving eye. Lock in place.

3. If the receiving eye indicator light is dim, realign

either sensor.

• 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.

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. (If bulbs are not

installed, 10 clicks can be heard.) See page 21.

ADJUSTMENT STEP 1

WARNING

Without a properly installed safety reversal system,

persons (particularly small children) could be

SERIOUSLY INJURED or KILLED by a closing garage

door.

• Incorrect adjustment of garage door travel limits will

interfere with proper operation of safety reversal

system.

Adjust the UP and DOWN Travel

Limits

Limit adjustment settings regulate the points at which

the door will stop when moving up or down.

To operate the opener, press the Door Control push

bar. Run the opener through a complete travel cycle.

• Does the door open and close completely?

• If one control (force or travel limits) is adjusted, the

other control may also need adjustment.

• After any adjustments are made, the safety reversal

system MUST be tested. Door MUST reverse on

contact with one-inch high object (or 2x4 laid flat) on

floor.

• 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 Adjustment Step 3, page 30).

Adjustment procedures are outlined below. Read the

procedures carefully before proceeding to

Adjustment Step 2. Use a screwdriver to make limit

adjustments. Run the opener through a complete

travel cycle after each adjustment.

CAUTION

To prevent damage to vehicles, be sure fully open door

provides adequate clearance.

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: If 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.

• If the door reverses when closing and there is

no visible interference to travel cycle:

Increase down travel. Turn the down limit

adjustment screw counterclockwise. One turn

equals 2" of travel.

If the opener lights are flashing, the Safety

Reversing Sensors are either not installed,

misaligned, or obstructed. See Troubleshooting,

page 23.

If door still won't close completely and the trolley

bumps into the pulley bracket (see page 4 or 5),

try lengthening the door arm (page 26) and

decreasing the down limit.

Test the 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.

• If the opener reverses in fully closed position:

Decrease down travel. Turn the down limit

adjustment screw clockwise. One turn equals 2"

of travel.

ADJUSTMENT STEP 2

WARNING

Without a properly installed safety reversal system,

persons (particularly small children) could be

SERIOUSLY INJURED or KILLED by a closing garage

door.

Adjust the Force

Force adjustment controls are located on the back

panel of the motor unit. Force adjustment settings

regulate the amount of power required to open and

close the door.

• Too much force on garage door will interfere with

proper operation of safety reversal system.

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.

• NEVER increase force beyond minimum amount

required to close garage door.

• NEVER use force adjustments to compensate for a

binding or sticking garage door.

• If one control (force or travel limits) is adjusted, the

other control may also need adjustment.

• After any adjustments are made, the safety reversal

system MUST be tested. Door MUST reverse on

contact with one-inch high object (or 2x4 laid flat) on

floor.

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. If anything interferes with the

door’s downward travel (including binding or

unbalanced doors), it will reverse.

Force Adjustment Controls

HOW AND WHEN TO ADJUST THE FORCES

1. 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 one-inch

obstruction. See Adjustment Step 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

adjustments until the door reverses normally. After

each adjustment, run the opener through a

complete cycle.

BACK PANEL

• 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 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.

2. 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,

ADJUSTMENT STEP 3

WARNING

Test the Safety Reversal System

Without a properly installed safety reversal system,

persons (particularly small children) could be

SERIOUSLY INJURED or KILLED by a closing garage

door.

TEST

• With the door fully open, place a one-inch board

(or a 2x4 laid flat) on the floor, centered under the

garage door.

• Safety reversal system MUST be tested every month.

• If one control (force or travel limits) is adjusted, the

other control may also need adjustment.

• After ANY adjustments are made, the safety reversal

system MUST be tested. Door MUST reverse on

contact with one-inch high object (or 2x4 laid flat) on

the floor.

• Operate the door in the down direction. The door

must reverse on striking the obstruction.

ADJUST

• 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.

NOTE: 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.

• Repeat the test.

• 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.

IMPORTANT SAFETY CHECK:

Repeat Adjustment Steps 1, 2 and 3 after:

• Each adjustment of door arm length, limits, or

force controls.

• Any repair to or adjustment of the garage door

(including springs and hardware).

2x4 laid flat

• Any repair to or buckling of the garage floor.

• Any repair to or adjustment of the opener.

• Does the opener have electric power? Plug a lamp

into the outlet. If it doesn't light, check the fuse box

or the circuit breaker. (Some outlets are controlled

by a wall switch.)

• Have you disabled all door locks? Review

installation instruction warnings on page 11.

• Is there a build-up of ice or snow under the door?

The door may be frozen to the ground. Remove

any restriction.

• The garage door spring may be broken. Have it

the Door Control:

• Manually operate door. If it is unbalanced or

binding, call a trained door systems technician.

• Is the door control lit? If not, remove the bell wire

from the motor unit terminals. Short the red and

white terminals by touching both terminals at the

same time with a piece of wire. If the opener runs,

check for a faulty wire connection at the door

control, a short under the staples, or a broken

wire.

• Check to be sure door opens & closes fully. Adjust

limits and/or force if necessary. (See pages 28

and 29.)

• Repeat the safety reverse test. Make any

necessary adjustments. (See page 30.)

Twice a Year

• Check chain tension. Disconnect trolley first. Adjust

if necessary (see page 11).

• Are the wiring connections correct? Review

Installation Step 6, page 18.

Once a Year

3. The door operates from the Door Control, but

not from the remote control:

• Oil door rollers, bearings and hinges. The opener

does not require additional lubrication. Do not

grease the door tracks.

• Is the door push bar flashing? If your model has

the Lock feature, make sure it is off.

THE REMOTE CONTROL BATTERY

• Program the opener to match the remote control

code. (Refer to instructions on the motor unit

panel.) Repeat with all remotes.

WARNING

To prevent possible SERIOUS INJURY or DEATH:

• NEVER allow small children near batteries.

• If battery swallowed, immediately notify doctor.

4. The remote control has short range:

• Change the location of the remote control in your

car.

• Check to be sure the antenna on the side or back

panel of motor unit extends fully downward.

• Some installations may have shorter range due to

a metal door, foil backed insulation, or metal

garage siding.

The lithium battery should produce

power for up to 5 years. To

replace battery, use the visor

clip or screwdriver blade to pry

open the case as shown. Insert

battery positive

5. Opener noise is disturbing in living quarters of

home:

11. The door reverses for no apparent reason and

opener lights blink for 5 seconds after

reversing:

Having a Problem? (Continued)

6. The garage door opens and closes by itself:

• Be sure that all remote control push buttons are

off.

• Check the safety reversing sensor. Remove any

obstruction or align the receiving eye. See

Installation Step 10.

• Remove the bell wire from the door control

terminals and operate from the remote 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 motor unit.

12. The opener lights don't turn on:

• Replace the light bulbs (75 watts maximum). Use a

standard neck garage door opener bulb if regular

bulb burns out.

• Clear memory and re-program all remote controls.

13. The opener lights don't turn off:

7. The door doesn't open completely:

• Is the Light feature on? Turn it off.

• Is something obstructing the door? Is it out of

balance, or are the springs broken? Remove the

obstruction or repair the door.

14. The opener strains or maximum force is

needed to operate door:

• The door may be out of balance or the springs

may be broken. Close the door and use the

emergency release handle to disconnect the

trolley. Open and close the door manually. A

properly balanced door will stay in any point of

travel while being supported entirely by its springs.

If it does not, disconnect the opener and call a

trained door systems technician. Do not increase

the force to operate the opener.

• If the door is in good working order but now

doesn't open all the way, increase the up force.

See Adjustment Step 2.

• If the door opens at least 5 feet, the travel limits

may need to be increased. One turn equals 2

inches of travel. See Adjustment Step 1.

Repeat the safety reverse test after the adjustment is

complete.

8. The door stops but doesn't close completely:

15. The opener motor hums briefly, then won't

work:

• Review the travel limits adjustment procedures on

page 28.

• The garage door springs may be broken. See

above.

Repeat the safety reverse test after any adjustment

of door arm length, close force or down limit.

• If the problem occurs on the first operation of the

opener, door may be locked. Disable the door lock.

9. The door opens but won't close:

Repeat the safety reverse test after the adjustment is

complete.

• If the opener lights blink, check the safety

reversing sensor. See Installation Step 10.

16. The opener won't operate due to power

failure:

• If the opener lights don’t blink and it is a new

installation, check the down force. See Adjustment

Step 2, page 29. For an existing installation, see

below.

• Use the emergency release handle to disconnect

the trolley. The door can be opened and closed

manually. When power is restored, press the Door

Control push bar and trolley will automatically

reconnect (unless trolley is in lockout position.)

See page 32.

Repeat the safety reverse test after the adjustment

is complete.

10. The door reverses for no apparent reason and

opener lights don’t blink:

• The Outside Quick Release accessory (for use on

garages with no service door) disconnects the

trolley from outside the garage in case of power

failure.

• Is something obstructing the door? Pull the

emergency release handle. Operate the door

manually. If it is unbalanced or binding, call a

trained door systems technician.

17. The chain droops or sags:

• Clear any ice or snow from the garage floor area

where the door closes.

• It is normal for the chain to droop slightly in the

closed door position. Use the emergency release

rope and handle to disconnect the trolley. If the

chain returns to the normal height when the trolley

is disengaged, and the door reverses on a 2x4 laid

flat, no adjustments are needed. (See page 11.)

• Review Adjustment Step 2 on page 29.

• If door reverses in the fully closed position,

decrease the travel limits (Adjustment Step 1).

Repeat safety reverse test after adjustments to force

or travel limits. The need for occasional adjustment

of the force and limit settings is normal. Weather

conditions in particular can affect door travel.
