The following symbols are placed in front of instructions to avoid personal injury or property damage. Read

these instructions carefully.

CAUTION Personal injury or property damage

mportant safety information

- The installer (specialist) must carefully read and understand these instructions before starting any work. Before first use and at least annually a specialist must inspect powered windows, doors and gates regarding their safe condition. Specialist according to EN12635 is, who on the basis of their technical training and experience, has sufficient knowledge in the field of powered windows, doors and gates and moreover is familiar with relevant state occupational safety regulations and generally accepted rules of technology in such an extent that he is also able to assess the safe working condition of powered windows, doors and gates.

- The door should be balanced. Unmoving or stuck doors must be repaired. In an unbalanced state, garage doors, door springs, cables, discs, brackets and rails are under extreme tension, which can lead to serious injury. Do not attempt to loosen, move or realign the door, but contact service centre or a door professional.

- During the installation or maintenance of a door opener, no jewellery, watches or loose clothing should be worn.

- To avoid serious personal injury due to entanglement, remove all cables and chains connected to the door before installing the door opener.

- During installation and electrical connection, the local building and electrical regulations must be observed.

This device complies with Protection Class 2 and does not require grounding.

- To avoid damage to very light doors (such as fibre glass, aluminium or steel doors), an appropriate reinforcement should be added. To do so, contact the door manufacturer.

- The automatic safety reverse system should undergo a test. Upon contact with a 50 mm high barrier on the ground, the garage door MUST return. Failure to properly adjust the door opener can result in serious personal injury from a closing garage door. Repeat test once a month and make any needed changes.

- This system must not be installed in damp or wet areas.

CAUTION Danger due to electrical current or voltage

- To remind all operators of the safe operation, in addition to the illuminated wall switch a warning sign to protect children should be affixed. The warning signs about the risk of trapping should be placed in clearly visible spots.

- Children should be supervised to ensure that they do not play with the device.

- This device is not intended for use by persons (including children) with restricted physical, sensory or mental abilities or lack of experience and/or knowledge, unless they are supervised by a person responsible for their device.

- All barriers / locks are deactivated to avoid damage to the door.

- If necessary, installed control equipment MUST be mounted within sight of the door and out of reach of children. Children should not be allowed to operate the buttons or remote controls. Misuse of the door opener can result in serious injury.

- The door opener should ONLY be used if the operator can see the entire door area and is assured that it is free of obstacles and the door opener is set correctly. No one may pass through the door while it is moving. Children must not be allowed to play in the vicinity of the door.

- Use the manual release only for the separation of the carriage from the drive and – if possible – ONLY with the door closed. Do not use the red handle to push the door up or pull it down.

- Before performing any repairs or removing covers, the door opener should be separated from the electric power supply.

- This product has a transformer with a special power cord. In case of damage this MUST be replaced with an original transformer by aqualified technician.

- Operation of the emergency release can lead to uncontrolled movements of the door, if springs are weak or broken or if the door is unbalanced.

- During operation, the gate should not under any circumstances obstruct public passageways.

- Mount the release handle of the emergency release at a height less than1.80 m.

• Wireless Entry Keypad: This is an accessory that opens the door using a four digit keycode.

When the opener is activated:

• If open, the door will close. If closed, the door will open

• If closing, the door will stop

• If opening, the door will stop (allowing space for entry and exit of pets and for ventilation)

• If the door has been stopped in a partially open or closed position, it will reverse direction

CARE OF YOUR OPENER

hen properly installed, your opener will operate with

W minimal maintenance. The opener does not require additional lubrication.

Limit and Force Settings: These settings must be

hecked and properly set when the opener is installed.

c Weather conditions may cause some minor changes in the door operation, requiring some re-adjustments, particularly during the first year of operation. Refer to limit and force setting in section 14.

Follow the instructions carefully and repeat the safety reverse test after any adjustment.

Transmitter:Additional transmitters can be purchased

at any time. Refer to www.liftmaster.eu for compatible transmitters. Any new transmitters must be programmed into the opener.

Transmitterbattery: If the transmission range decreases, replace the battery.

Obstruction behaviour:

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

• If an obstruction is encountered while opening, the door will reverse and stop

• Obstruction detection beams use 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 or pets.

Opening the door manually:

When releasing the door, the door should be fully closed if possible. Weak or broken springs could allow an open door to fall rapidly. Property damage or serious injury could result.

The door can be opened manually by pulling the release cord down firmly. To re-engage the door, pull the release cord down firmly.

The opener light will turn on for 3 minutes when the opener is activated.

MAINTENANCE OF YOUR OPENER

Once a Month:

• Repeat the safety reverse test (see section 15). Make any necessary adjustments.

• Manually operate the door. If it is unbalanced or binding, call for professional garage door service.

• Check to be sure that the door opens and closes fully. Set the limits and/or force if necessary.

TROUBLESHOOTING

. The opener will not operate from either the

UP/DOWN activation button or the transmitters :

• Does the opener have electric power? Plug a lamp into the outlet. If it does not work, check the fuse box.

• Have you disabled all door locks? Review the

nstallation safety instruction warnings on page 1.

• 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 replaced by contacting a garage door repairer.

2. Opener operates from the transmitter, but not

from the wired wall control terminals:

• Check that the wiring connections are correct.

3. The door operates from the UP/DOWN activation

buttons but not from the wireless wall control or transmitter:

• Program the opener to match the transmitter code. Repeat with all transmitters.

4. The transmitter has short range:

• Change the location of the transmitter.

• Check to be sure the antenna on the bottom of the opener extends fully downward.

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

• The batteries may be flat. Replace the batteries.

5. The garage door opens and closes by itself:

• Be sure that no transmitter buttons are being pressed.

• Clear the memory and re-program all wireless wall controls and transmitters.

8. The door opens but will not close (or reverses while closing):

• Is something obstructing the door? Pull the manual

release handle. Operate the door manually. If it is

nbalanced or binding, call a trained door systems

u technician.

• Clear any ice or snow from the garage floor area where

the door closes.

• Repeat the limit and force setting. Repeat safety reverse

est after adjustments.

9. The opener strains to operate the door:

• The door may be out of balance or the springs may be

broken. Close the door and use the manual release 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 opener and call a trained door systems technician.

10. The opener motor hums briefly, then will not

work:

• Check that the door is not in manual release mode

(refer to sections 9 or 10).

• The garage door springs may be broken.

• If the problem occurs on the first operation of the

opener, the door may be locked. Disable any door locks.

11. The opener will not operate due to a power

failure:

• Use the manual release handle to disconnect the door.

The door can be opened and closed manually. When power is restored, re-engage the opener to operate it via a transmitter.

6. The door reverses and stops before opening completely:

• Is something obstructing the door? Is it out of balance,

or are the springs broken? Remove the obstruction or repair the door.

7. Door reverses for no apparent reason and opener lights flash 10 times:

• Check the obstruction detection beams (if you have

installed this accessory). If the red light on the beam is flashing, the alignment is incorrect.

• The red light on the beams may not be on if the

opener is in Standby mode. Activate the door to temporarily exit standby mode and check lights are on constantly. If the LEDs are flashing, realign the beams.

12. The LED Indicators on the control panel are flashing in sequence:

• Check the diagnostic code in section 28.
