Failure to comply with the following instructions may result in serious personal injury or property damage.

• Read these instructions carefully
• The garage door opener is designed and tested to offer reasonable safe service provided it is installed and operated in strict accordance with the instructions in this manual.

These safety alert symbols mean Warning - a personal safety or property damage instruction. Read these instructions carefully.

Keep garage door balanced. Do not let the garage door opener compensate for a binding or sticking garage door. Sticking or binding doors must be repaired. Garage doors, door springs, cables, pulleys, brackets and their hardware are under extreme tension and can cause serious personal injury. Do not attempt to loose, move or adjust them. Call for garage door service.

Do not wear rings, watches or loose clothing while installing or servicing a garage door opener.

To avoid serious personal injury from entanglement, remove all ropes connected to the garage door before installing the door opener.

Installation and wiring must be in compliance with your local building and electrical codes.

Lightweight doors of fiberglass, aluminum or steel must be substantially reinforced to avoid door damage. (See page 3.) The best solution is to check with your garage door manufacturer for an opener installation reinforcement kit.

The safety reverse system test is very important. Your garage door MUST reverse on contact with a 40mm obstacle placed on the floor. Failure to properly adjust the opener may result in serious personal injury from a closing garage door. Repeat the test once a month and make any needed adjustments.

This unit should not be installed in a damp or wet space.

Door must not extend over public byway during operation.

Drive can NOT be used with a driven part incorporating a wicket door (unless the drive cannot be operated with the wicket door opened)

The Protector System must be installed when the force at the edge of the closing door force exceeds 400N (40kg). Excessive force will interfere with the proper operation of the Safety Reverse System or damage the garage door.

Permanently fasten the caution label adjacent to the wall-mounted door control control button as a reminder of safe operating procedures.

Disengage all existing garage door locks to avoid damage to garage door.

Install the lighted door control button (or any additional push buttons) in a location where the garage door is visible, at a height of at least 1.5m and out of the reach of children. Do not allow children to operate push button(s) or remote control(s). Serious personal injury from a closing garage door may result from misuse of the opener.

Activate opener only when the door is in full view, free of obstructions and opener is properly adjusted. No one should enter or leave the garage while the door is in motion. Do not allow children to play near the door.

Use manual release only to disengage the trolley and, if possible, only when the door is closed. Do not use the red handle to pull the door open or closed.

Disconnect electric power to the garage door opener before making repairs or removing covers.

This product is provided with a power supply cord of special design which, if damaged, must be replaced by a power supply cord of the same type; such a power supply cord may be obtained and fitted by a specialist.

PROGRAMMING

36

37

Your door operator has already been programmed at the factory to operate with your hand-held remote control. The door will open and close when you press the large push button.

Below are instructions for programming your operator to operate with additional remote controls.

To Add or Reprogram a Hand-held Remote Control

USING THE "LEARN" BUTTON

1. Press and release the orange "learn" button on the motor unit. The learn indicator LED will glow steadily for 30 seconds.
2. Within 30 seconds, press and hold the button on the hand-held remote that you wish to operate your door.
3. Release the button when the motor unit LED two clicks.

To Erase All Codes From Motor Unit Memory

To deactivate any unwanted remote, first erase all codes:

Press and hold the "learn" button on motor unit until the learn indicator LED goes out (approximately 6-9 seconds). All previous codes are now erased. Reprogram each remote or keyless entry you wish to use.

The Remote Control Battery

WARNING

To prevent possible SERIOUS INJURY or DEATH:

• NEVER allow small children near batteries.
• If battery is swallowed, immediately notify doctor.

TROUBLESHOOTING

1. The operator doesn't operate from either the Door Control or the remote control:

2. Does the operator 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.)

3. Have you disabled all door locks? Review installation instruction warnings.
4. Is there a build-up of ice or snow under the door? The door may be frozen to the ground. Remove any restriction.

5. The door spring may be broken. Have it replaced.

6. Opener operates from the remote, but not from the Wireless Wall Control:

7. Check the LED on the Wall Control to ensure the LED turns on when button is pushed. If the LED is weak or not on Change the batteries. (Remove cover and replace with correct batteries)

8. If the LED turns on and is strong check to ensure the unit is programmed into the unit.

9. The door operates from the Door Control, but not from the remote control:

10. Is the door push bar flashing? If so, Lock mode is engaged. Make sure it is off by pressing the Lock button for two seconds.

11. Program the operator to match the remote control code. (Refer to instructions on the motor unit panel.) Repeat with all Remote.

12. The remote control has short range:

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

14. Check to be sure the antenna on the side or back panel of motor unit extends fully downward.

15. Some installations may have shorter range due to a metal door, foil backed insulation, or metal siding.

16. The door opens and closes by itself:

17. Be sure that all remote control push buttons are off.

18. 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 control console and the motor unit.

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

20. The door doesn't open completely:

21. Check power door lock.
    Is something obstructing the door? Is it out of balance, or are the springs broken? Remove the obstruction or repair the door.

22. The door opens but won't close:

23. Check cable tension monitor (see installation step 4).

24. If the operator clicks, check the safety reversing sensor. See Installation Step 9.
    If the operator does not click and it is a new installation. See Adjustment Step 2. For an existing installation, see below.

Repeat the safety reverse test after the adjustment is complete.

1. The door reverses for no apparent reason and operator LED doesn't blink:

2. Check cable tension monitor (see installation step 4).

3. 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.
   Clear any ice or snow from the floor area where the door closes.
   Review Adjustment Step 2.

Repeat safety reverse test after adjustments.

1. The door reverses for no apparent reason and operator LED blinks for 5 seconds after reversing:
2. Check the safety reversing sensor. Remove any obstruction or align the receiving eye.
3. The operator strains to operate door:

4. 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 door. 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 operator and call a trained door systems technician.

5. The operator motor hums briefly, then won't work:

The door springs may be broken. See above.
- If the problem occurs on the first operation of the operator, door may be locked. Disable the power door lock.

1. The operator won't operate due to power failure:

2. Manually open the power door lock.

3. Use the emergency release handle to disconnect the door. The door can be opened and closed manually. When power is restored, pull manual release a second time.
   If an EverCharge Unit is connected, the operator should be able to operate up to 20 times without power.

4. Door loses limits.

5. Collar not tightened securely. Tighten collar (see Assembly Steps 1 and 2) and reprogram limits (see Adjustment Step 1).

6. The operator moves when the door is in operation:

7. Some minor movement is normal for this product. If it is excessive the collar will wear prematurely.

8. Check to make sure the torsion bar is not moving left/right excessively.
9. Check to make sure the torsion bar is not visibly moving up and down as it rotates.

10. Check that the operator is mounted at a right angle to the jackshaft. If not, move the position of the mounting bracket.

11. Power lock makes noise when operating.

Call Chamberlain-Liftmaster dealer for replacement power lock.
