• 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" - 18x1-7/8" 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.
Grease the top and underside of the rail surface where the trolley slides. A tube of grease is supplied.

Installation Step 6

Install the Multi-Function Door Control Panel

• Strip 1/4" of insulation from one end of the bell wire; connect the wire to the two screw terminals on the back of the door control by color: white to 2 and white/red to 1.
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.
Fasten the Multi-Function Door Control securely with 6ABx1" screws. If installing into drywall, drill 5/32" holes and use the anchors provided.
• 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.
• Receiver terminal screws and the antenna are located on the right panel of the opener. Position the antenna wire as shown.
• Then connect the bell wire to the opener terminal screws: white to 2 and white/red to 1.
Remember to affix the User Safety Instruction
label to the wall near the door control, and the Maintenance Instruction label in a prominent location on the inside of the garage door.
If the label adhesive will not adhere to your garage wall surface (or becomes loose with time) use tacks to secure the label alongside the door control.

Fasten Door Bracket

Follow instructions which apply to your door type as illustrated below or on page 21.
A horizontal brace should be long enough to be secured to 2 vertical supports. A vertical brace should cover the height of the top panel.
The illustration shows one piece of angle iron as the horizontal brace. For the vertical brace, 2 pieces of angle iron are used to create a "U"-shaped support. The best solution is to check with your garage door manufacturer for an opener installation, door reinforcement kit.
To prevent damage to steel, aluminum, fiberglass or glass panel doors, always reinforce the inside of the door both vertically and horizontally with an angle iron.

Do not increase the force
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 one inch obstruction. See page 26.) 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.
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

IMPORTANT SAFETY INSTRUCTIONS
To reduce the risk of severe injury or death to persons:
1. READ AND FOLLOW ALL INSTRUCTIONS.
2. Do not permit children either to operate or to play with the opener. Keep remote control in a location inaccessible to children.
3. Operate opener only when the door is in full view and free from any obstruction. Keep the door in sight until it is completely closed. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.
4. Check safety reversal system monthly. See page 26. The garage door
MUST
reverse on contact with a one inch object (or a 2x4 board laid flat) placed on the floor. If an adjustment is made to one of the controls (either force or limits of travel), the other control may need to be adjusted also, and the safety reversal system
must
be checked.
Failure to properly adjust the opener may result in severe
injury or death.
5. If possible, use the manual release only when the door is in a closed position. Caution should be taken whenever the disconnect cord is actuated with the door open.
Weak or broken springs may
cause the door to fall rapidly, causing injury or death to persons.
6. KEEP GARAGE DOORS PROPERLY BALANCED. See page 4.
An improperly balanced door may not
reverse when required and could result in severe injury or death.
Repairs to cables, spring assemblies
and other hardware must be made by a professional garage door person.
7. Disconnect the electric power to the garage door opener before making any repairs or removing the covers.

Having a Problem?

Situation Probable Cause & Solution
The opener doesn't operate from either the door control or the remote control:
Opener operates from remote control, but not from door control:
The door operates from the door control, but not from the remote control:
1. 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.)
2. Have you disabled all door locks? Review installation instruction warnings on Page 7.
3. Is there a build-up of ice or snow under the door? The door may be frozen to the ground. Remove any restriction.
4. The garage door spring may be broken. Have it replaced.
5. Repeated operation may have tripped the overload protector in the motor. Wait 15 minutes. Try again.
1. Is the door control push bar lit? If not, Remove the bell wire from the opener terminal screws. 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.
2. Are the wiring connections correct? Review Step 6, page 14.
1. If your model has the Lock feature, turn it
2. Is the wall push button flashing? Your opener needs to re-learn a remote control code. Refer to instructions on the opener panel.
3. Does the battery test light glow when the remote control push button is pressed? If not, replace the battery.
4. Program the receiver to match the remote control code.
5. Repeat the receiver programming procedure with all remote controls.

The remote control has short range:
Opener noise is disturbing in living quarters of home:
The garage door opens and closes by itself:
The door doesn't open completely:
1. Check the battery test light. If the light is dim, replace the battery.
2. Change the location of the remote control in your car.
3. Check to be sure the antenna on the side or back panel of the opener extends fully downward.
4. Some installations may have shorter range due to a metal door, foil backed
insulation, or metal garage siding.
If operational noise is a problem because of proximity of the opener to the living quarters, the Vibration Isolator Kit 41A3263 can be installed. This kit was designed to minimize vibration to the house and is easy to install.
1. Be sure that all remote control push buttons and battery indicator lights are off.
2. Remove the bell wire from the door control terminals and operate from the remote control 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 opener.
1. If the door has been working properly but now doesn't open all the way, increase the
up force.
2. Is something obstructing the door? Remove the obstruction or repair the door.
3. If door opens at least 5 feet, the travel limits may need to be increased. One turn equals 2 inches of travel. See page 24.
See page 25.
Repeat the safety reverse test after the adjustment is complete.
The door stops but doesn't close completely:
Review the travel limits adjustment procedures on page 24.
Repeat the safety reverse test after any adjustment of door arm length, close force or down limit.

2. Clear any ice or snow from the garage floor area where the door closes.
3. Review the force adjustment procedures on page 25.
4. If door reverses in the
