WARNING

CAUTION

WARNING

During assembly, installation and adjustment of the opener, instructions will call for hand tools shown below.

An unbalanced garage door might not reverse when required and someone under the door could be seriously injured or killed.

If your garage door binds, sticks or is out of balance, call for professional garage door service.

Garage doors, door springs, cables, pulleys, brackets and their hardware are under extreme tension and can cause serious injury or death.

Do not try to loosen, move or adjust

them yourself!

Ropes left on a garage door could cause someone to become entangled and killed.

Remove all ropes connected to the door before installing and operating the opener.

Identify the type and height of your door and any special conditions that exist and any additional materials that may be required by referring to the lists on page 4 or page 5.

To avoid damage to the garage door and opener, disable locks before installing and operating the opener. Use a wood screw or nail to hold locks in the "open" (unlocked) position.

Operation at other than 120V 60 Hz will cause opener malfunction and damage.

Before you begin, complete the following test to make sure your door is balanced, and is not sticking or binding:

• Lift the door about halfway as shown. Release the door. It should stay in place, supported entirely by its springs.

• Raise and lower the door to see if there is any binding or sticking.

To avoid installation difficulties, do not run the garage door opener until instructed to do so.

Assembly Step 1

Assemble the T-rail & Attach the Cable Pulley Bracket

• Align the 3 T-rail sections on a flat surface exactly as shown. The end sections are identical. Make sure the "arrow label" on the center section is pointing toward the door.

• Insert the carriage bolts so the square bolt necks seat in the square holes in the T-rail end sections and pass through the round holes in T-rail center section. Assemble lock nuts, ensure alignment and tighten.

If T-rail is not assembled EXACTLY as shown, trolley will not travel smoothly along length of rail or it will hit against the nuts.

Make sure bolt necks are seated in the square holes and rails are aligned before you tighten lock nuts. (See right and wrong views). Improper assembly can cause jerky trolley operation, noise and/or nuisance door reversals.

Right Wrong

Hardware Shown Actual Size

• Position the cable pulley bracket on the front end of the T-rail as shown. Fasten securely with the hardware.

When tightening the screws, be sure to keep bracket parallel to the rail. Otherwise, the rail may bow when opener is operated.

Installation procedures are the same for sectional and one-piece doors.

Be sure power to the opener is disconnected.

The sending eye transmits an invisible light beam to the receiving eye. The units can be installed on either side of the garage door as long as the sun never shines directly into the receiving eye lens.

Look at the label on the connector end of each case to identify the sensors.

The brackets must be connected and fastened so that the sending and receiving eyes face each other as shown in Figure 1.

If an obstruction breaks the light beam while the garage door is closing, the door will stop and reverse to full open position and the opener lights will flash for 5 seconds.

Without a properly working safety reversing sensor, persons (particularly children) could be injured or killed by a closing garage door.

Read and follow all instructions. To protect small children, install the safety

reversing sensor so that the beam will be no higher than 4"-6" above the garage floor.

Disconnect power to the garage door opener before installing the safety reversing sensor.

The brackets surface such as the studs on either side of the door, or add a piece of wood at each location if installing in masonry construction.

The invisible light beam path must be unobstructed. No part of the garage door (or door tracks, springs, hinges, rollers or other hardware) can interrupt the beam while the door is closing. If it does, use a piece of wood to build out each sensor mounting location to the minimum depth required for light beam clearance.

Fasten Door Bracket

Follow instructions which apply to your door type as illustrated below or on page 25.

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.

SECTIONAL Door Installation Procedure

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.

Figure 1

• Center the door bracket on the previously marked vertical guideline used for the header bracket installation.

Note correct UP placement, as

stamped inside the bracket.

• Position the bracket on the face of the door within the following limits:

A) The top edge of the bracket 2"-4" below the top

edge of the door.

B) The top edge of the bracket directly below any

structural support across the top of the door.

• Mark and drill 5/16" left and right fastening holes. Secure the bracket as shown in Figure 1 if there is vertical reinforcement.

If your installation doesn't require vertical reinforcement but does need top and bottom fastening holes for the door bracket, fasten as shown in Figure 2.

Situation Probable Cause and Solution

The opener doesn't operate from either the Door Control or the remote control:

Opener operates from the remote control, but not from the 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 door switch.)

2. Have you disabled all door locks? Review installation instruction warnings on Page 11.

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 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 18.

1. Is any door push button flashing? If your model has the Lock feature, make sure the lock is Off.

2. Your opener needs to re-learn a remote control code. Refer to Instructions on the opener panel.

3. Program the receiver to match the remote control code.

4. 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. Change the location of the remote control in your car.

2. Check to be sure the antenna on the side or back panel of opener extends fully downward.

3. Some installations may have shorter range due to a metal door, foil backed insulation, or metal garage siding. (Antenna Extender Kit 41A3504)

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 are not stuck in the “ON” position.

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.

3. Clear memory and re-program all remote controls.

1. Is something obstructing the door? Remove the obstruction or repair the door.

2. If the door has been working properly but now doesn't open all the way, increase the

up force.

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 28.

See page 29.

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 28.
