Start by Reading These Important Safety Instructions

General safety guidelines

Before you begin the installation:
Please read the operating instructions and especially the precautions. Keep the manual for future reference

and pass it on to a possible subsequent owner.

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

these instructions carefully.

Important 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.

- 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 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.

- Mount the release handle of the emergency release

at a height less than1.80 m.
