CAUTION
Personal injury or property damage
Important safety information
The automated door opening system has been as a matter of course tested and designed for safe operation, but safety can be assured only if the
safety instructions listed below are strictly adhered to during installation and operation.
- 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 specialist.
- 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.
- During operation, the gate should not under any circumstances obstruct public passageways.
- 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 safety or have received instruction in how to use the 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 cable. In case of damage this MUST be replaced with an original transformer by a qualified
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.
- Mount the release handle of the emergency release at a height less than 1.80 m.
- The drive must not be used with a door incorporating a wicket door.
