START BY READING THESE IMPORTANT SAFETY RULES

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

This garage door opener is designed and tested to offer reasonable safe service provided it is installed and operated in strict accordance with the following safety rules.

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

Caution: If your garage has no service entrance door, Model 1702EML Outside Quick Release must be installed. This accessory allows manual operation of the garage door from outside in case of power failure.

Keep garage door balanced. Sticking or binding doors must be repaired. Garage doors, door springs, cables, pulleys, brackets and their

tension and can cause attempt to loosen, move 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. Connect the power supply cord only to properly earthed mains.

Lightweight doors of fiberglass, aluminum or steel must be substantially reinforced to avoid door damage. (See page 4.) 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 50mm 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.

The force, as measured on the closing edge of the door, should not exceed 150 N (15kg). If the closing force is

Safety Reverse System or damage the garage door.

Fasten the caution label adjacent to the lighted door 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, but 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 from your local Chamberlain distributor and must be fitted by a specialist.

ADJUSTMENT SECTION 21 – 23

LIMIT ADJUSTMENT – 21

Run the opener through a complete travel cycle. Limit adjustments are not necessary when the door opens and closes completely and doesn't reverse unintentionally in the fully closed position.

Situations requiring limit adjustment are listed below. Run the opener through a complete travel cycle after each adjustment.

Note: Repeated operation of the opener during adjustment procedures may cause motor to overheat and shut off. Allow a

15 minute cooling period after 5 continuous operations of the opener.

Read the following carefully before proceeding to Force Adjustment. Use a screwdriver to make limit adjustments.

If Door Doesn't Open Completely but Opens at Least 1,5m

(5 feet): Increase up travel. Turn the up limit adjustment screw (1) clockwise. One turn equals 5cm (2") of travel.

If door does not open at least 1,5m (5 feet): Adjust up (open) force. See Force Adjustment.

If Door Doesn't Close Completely:If door arm is at maximum length, increase down travel. Turn down limit adjustment screw (2) counterclockwise. One turn equals 5cm (2") of travel. If the door still will not close completely, the header bracket is positioned too high.

If Opener Reverses in Fully Closed Position: Decrease down travel. Turn down limit adjustment screw (2) clockwise. One turn equals 5cm (2") of travel.

If Door Reverses when Closing and there is no Interference to Travel Cycle: Test door for binding. Pull manual release handle. Manually open and close door. If door is binding, call a door serviceman. If door is not binding or unbalanced, adjust down (close) force.

114A2064I

FORCE ADJUSTMENT – 22

The force, as measured on the closing edge of the door, should not exceed 150 N (15kg). If the closing force is adjusted to more than 150 N, the Protector System must be installed.

Do not use force adjustments to compensate for a binding or sticking garage door. Excessive force will interfere with proper operation of safety reverse system or damage garage door.

Force Adjustment Controls (1 & 2) are located on the back panel of opener.

If the force adjustments are set too light, door travel may be interrupted by nuisance reversals in down direction and stops in up direction. Weather conditions can affect

occasional adjustment may be needed Maximum force adjustment range is complete turn. Do not force controls adjustment controls with a screwdriver.

Test Down (Close) Force: Grasp the door handle or door bottom when door is about halfway through down (close) travel. Door should reverse. (Reversal halfway through down travel does not guarantee reversal on a 50mm obstruction.) If the door is hard to hold or doesn't reverse, decrease down (close) force by turning the control (2) in a counterclockwise direction. Make small adjustments until door reverses normally. After each adjustment, run opener through a complete cycle.

If Door Doesn't Open at Least 1,5m (5 feet):Increase up (open) force by turning the control (1) in a clockwise direction. Make small adjustments until door opens completely. Re-adjust up limit if necessary. After each adjustment, run opener through a complete travel cycle.

If Door Reverses During Down (Close) Cycle: Increase down (close) force by turning the control (2) in a clockwise direction. Make small adjustments until door completes 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.

TEST THE SAFETY REVERSE SYSTEM – 23

The safety reverse system test is important. Garage door must reverse on contact with a 50mm obstacle laid flat on the floor. Failure to properly adjust opener may result in serious personal injury from a closing garage door. Repeat test once a month and adjust as needed.

Procedure: Place a 50mm obstacle (1) laid flat on the floor under the garage door. Operate the door in the down direction. The door must reverse on the obstruction. If the door stops on the obstruction, it is not traveling far enough in the down direction. Increase the down limit by turning down limit adjustment screw counterclockwise 1/4 turn.

Repeat test.

When the door reverses on the 50mm obstacle, remove the obstruction and run the opener through a complete travel cycle. Door must not reverse in closed position. If it does, adjust Limits and Force and repeat safety reverse test.

INSTALL THE PROTECTOR SYSTEMTM – 24 (See accessories)

The force, as measured on the closing edge of the door, should not exceed 150 N (15kg). If the closing force is adjusted to more than 150 N, the Protector System must be installed.

After opener has been installed and adjusted, The Protector System™ accessory can be installed. Instructions are included with this accessory.

The Protector System™ provides an additional measure of safety against a small child being caught under a garage door. It uses an invisible beam which, when broken by an obstruction, causes a closing door to open and prevents an open door from closing and is strongly recommended for homeowners with young children.

OPERATION OF YOUR OPENER

Your opener can be activated by any of the following devices:

•The Lighted Door Control Button (optional). Hold the button down until door starts to move.

•The Outside Keylock or Keyless Entry System (if you have installed either of these accessories).

3.If opening, the door will stop (allowing space for entry and exit of pets and for fresh air).

4.If the door has been stopped in a partially open position, it will close.

5.If an obstruction is encountered while closing, the door will reverse.

6.If an obstruction is encountered while opening, the door will stop.

7.The optional Protector System™ uses an invisible beam which, when broken by an obstruction, causes a closing door to open and prevents an open door from closing. It is STRONGLY RECOMMENDED for homeowners with young children.

Allow a 15 minute cooling period after 5 continuous operations of the opener.

The opener light will turn on: 1. when opener is initially plugged in; 2. when the power is interrupted; 3. when the opener is activated.

The light turns off automatically after 4-1/2 minutes. Bulb size is 40 Watts maximum (230V, E27), ESRS type.

CARE OF YOUR OPENER

When properly installed, opener will provide high performance with a minimum of maintenance. The opener does not require additional lubrication.

Limit and Force Adjustments: These adjustments must be checked and properly set when opener is installed. Only a screwdriver is required. Weather conditions may cause some minor changes in the door operation, requiring some re-adjustments, particularly during the first year of operation.

Refer to the limit and force adjustments on pages 4 & 5. Follow the instructions carefully and repeat the safety reverse test after any adjustment.

Remote Control Transmitter: The portable remote control may be secured to a car sun visor with the clip provided. Additional remotes can be purchased at any time for use in all vehicles using garage.

Refer to Accessories. The receiver must be programmed to operate with any new remote.

Remote Control Battery: The lithium batteries should produce power for up to 5 years. When the light becomes dim or does not come on, replace the battery. If transmission range lessens, check the battery test light.

Oil door rollers, bearings and hinges. The opener additional lubrication. Do not grease the door tracks

HAVING A PROBLEM?

1. Opener doesn't operate from remote control:

•Does the opener have electric power? Plug lamp into outlet. If it doesn't light, check the fuse box or the circuit breaker. (Some outlets are controlled by a wall switch.)

•Have you disengaged all door locks? Review installation instruction warnings on page 1.

•Is there a build-up of ice or snow under the door? The door may be frozen to ground. Remove any obstruction.

•The garage door spring may be broken. Have it replaced.

•Repeated operation may have tripped the overload protector in the motor. Wait 15 minutes. Try again.

2. Remote has short range:

•Is battery installed? Check battery test light. If the light is dim, change the battery.

•Change the location of the remote control on the car.

•A metal garage door, foil-backed insulation or metal siding will reduce the transmission range.

3. Door reverses for no apparent reason and opener light doesn't blink:

•Is something obstructing the door? Pull manual release handle. Operate door manually. If it is unbalanced or binding, call for professional garage door service.

•Clear any ice or snow from garage floor area where garage door closes.

•Review Force Adjustment.

•If door reverses in FULLY CLOSED position, decrease travel limits.

Repeat safety reverse test after adjustment is complete.

The need for occasional adjustment of the force and limit settings is normal. Weather conditions in particular can affect door travel.

4. Door reverses for no apparent reason and opener light blinks for 5 seconds after reversing:

Check The Protector System™ (if you have installed this accessory). If the light is blinking, correct alignment.

5. Opener noise is disturbing in living quarters of home:

If operational noise is a problem because of proximity of the opener to the living quarters, Vibration Isolator Kit 41A3263 can be installed. This kit was designed to reduce the "sounding board effect" and is easy to install.

6. The garage door opens and closes by itself:

Make sure remote push button is not stuck "on".

7. Door stops but doesn't close completely:

Review Travel Limits Adjustment.

6-GB

8. Door opens but won't close:

•Check The Protector System™ (if you have installed this accessory). If the light is blinking, correct alignment.

•If opener light does not blink and it is a new installation, check the down force.

Repeat the safety reverse test after the adjustment is complete.

9. Opener light does not turn ON:

Replace light bulb (40 Watts, 230V, E27 maximum). Replace burned out light bulbs with rough service light bulbs.

10. Opener light does not turn OFF:

There may be a defective earth at the ceiling or wall receptacle.

The unit must be earthed.

11.Opener strains or maximum force is needed to activate door:

Door may be unbalanced or springs are broken. Close door and use manual release rope and handle to disconnect trolley. Open and close door manually. A properly balanced door will stay in any point of travel while being supported entirely by its springs. If it does not, call for professional garage door service to correct the problem. Do not increase the force to operate the opener.

12.Opener motor hums briefly, then won't work:

•Garage door springs are broken. SEE ABOVE.

•If problem occurs on first operation of opener, door is locked. Disable door lock. If chain was removed and reinstalled, the motor may be out of phase. Remove chain; cycle motor to down position. Observe drive sprocket. When it turns in clockwise direction and stops in down position, re-install chain.

Repeat safety reverse test after adjustment is complete.

13. Opener won't activate due to power failure:

•Pull manual release rope and handle down and back to disconnect trolley. Door can be opened and closed manually. When the power is restored, pull the manual release handle straight down. The next time the opener is activated, the trolley will reconnect.

•The Outside Quick Release accessory (if fitted) disconnects the trolley from outside the garage in case of power failure.

14. The chain droops or sags:

It is normal for the chain to droop slightly in the closed door position. Use the manual 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 50mm obstacle laid flat, no adjustments are needed.
