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.

- 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.

TESTING THE DOOR

Complete the following test to ensure your door is well balanced, and not sticking or binding:

• Disable all locks and remove any ropes connected to the garage door.

Lift the door to about halfway and then release it. The

• door should remain spring balanced.

• Raise and lower the door to determine if there are any sticking or binding points (20 kg is the absolute maximum allowable to raise or lower the door in any position).

If your door does not hold in place or the door binds or sticks, call a qualified door technician before installing the opener.

ATTACHING THE STOP COLLAR

• The stop collar is required to be installed on the opposite side of the door to where the opener is to be

installed.

• Ensure the U-Bolt holding the door shaft to the door

bracket is tightly secure.

(NOTE: This U-Bolt must not be removed or loosened)

• Remove the bolt assembly from the plastic stop

collar. Open the collar as wide as possible and push it onto the door shaft.

• Fit the stop collar hard against the boss of the

door drum. Reinstall the bolt assembly onto the stop collar and tighten.

ATTACHING THE WEIGHT BAR (OPTIONAL*)

If the door has a lifting handle, remove the handle, nuts & bolts. Place the weight bar over the handle holes, insert the extended bolts through the weight bar & fasten the handle back in place.

• Place the weight bar in the centre of the door as shown.

SAFETY CHECK!

Is the stop collar installed?

YES: proceed to the next

step

NO: install the stop collar

before proceeding

If the door curtain does not have a handle you will need to follow these instructions:

• Use a marker pen to mark the two hole positions.

• Drill two 5.5 mm holes through the two marked positions, then place the weight bar on the inside of the door.

• Use the bolts, washers and nuts (provided) to fasten the weight bar in place.
