Important safety instructions for
installation
WARNING Incorrect installation can lead to severe injury. Follow all installation
instructions.
Garage doors are under great spring tension. Do not attempt to adjust spring tension. Do not
loosen any brackets under spring tension. Do not remove springs from the door. Merlin Ga-
rage Openers Limited do not accept responsibility for damage or injury resulting from install-
ing this opener. If you have any concerns please consider having the opener installed by an
Authorised Merlin Installer.
To avoid difficulty during installation, do not connect the opener to the mains or run the door
opener until instructed to do so.
Do not use force sensitivity adjustments to compensate for a binding or sticking garage door.
Excessive force may damage the garage door.
Before installing the drive remove all unnecessary ropes or chains and disable any equip-
ment, such as locks, that is not needed for powered operation.
Before installing the drive check that the door is in good mechanical condition and that it is
correctly balanced. Check that it opens and closes
properly.
Install the actuating member for the manual re-
lease (red handle on a rope) such that it rests at a
height of less than 1.8 m.
Install any fixed control, wired or wireless, within
sight of the door but away from moving parts and
at a height of more than 1.5 m.
Install the drive such that all moving parts (except
the door and the manual release) are at a height
of more than 1.8 m.
Permanently attach the label warning against en-
trapment in a prominent place, or near any fixed
control.
Permanently fix the label concerning the manual
release adjacent to its actuating member (thread
the cord through the holes in the manual release
warning card).
After installation, ensure that the mechanism is
properly adjusted and that the drive reverses when
the door contacts a 40 mm high object placed on
the floor.
The appliance is not intended for use by young
children or infirm persons without supervision.
If the supply cord is damaged, it must be replaced
by the manufacturer or its service agent or a simi-
larly qualified person in order to avoid a hazard.
