Important safety instructions for
installation
WARNING It is vital for the safety of persons to follow all instructions. Save
these instructions.
To prevent fire or shock hazard do not expose the opener to rain or moisture.
To avoid electrical shock do not open the cabinet without disconnecting the opener from the mains.
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 does not
accept responsibility for damage or injury resulting from installing this opener.
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 equipment, 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 corÂrectly balanced. Check that it opens and closes properly.
Install the actuating member for the manual release (red handle on a rope) such that it rests at a
height of less than 1.8m.
Install any fixed control, wired or wireless, within sight of the door but away from moving parts and
at a height of more than 1.5m.
Install the drive such that all moving parts (except the door and the manual release) are at a height
of more than 1.8m.
Permanently attach the label warning against entrapment 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 40mm (50mm for UK) 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
similarly qualified person in order to avoid a hazard.
CE compliance after installation (EC countries only)
It is the responsibility of the installer of the opener to ensure that the forces measured at the
leading edge of the door are within the guidelines of BSEN 60335-2-95:2001. This may require
adjustment of the drive and may also require adjustment of the door. Specialised measurement
equipment may be required. Contact Merlin for assistance if necessary. If the measured forces
exceed the guidelines then Merlin M102 non-contact sensors must be fitted.

Garage Door
This opener is designed for a residential roller door, maximum 3 metres high and 6 metres wide.

shaft.
There must be at least 60mm between the edge of the door drum and the supporting wall bracket.
There must be a drive spoke inside the drum closer than 130mm from the edge of the door drum.
If there is not then contact Merlin for an adapter.

Preparing the roller door
WARNING Do not loosen both door support brackets or clamps. Loosening both
door shaft clamps will expose you to the risk of serious personal injury.
STEP 1.
Check that there is a power point available and that there is adequate clearance to mount the
opener onto the door in your preferred location. Clearances are listed in the front of this manual.
STEP 2.
Roll the door up to the fully open position.
STEP 3.
Ensure that the U-bolt on the end of the door opposite the end to which the opener is to be fitted
is tightened securely. This U-bolt holds all the spring tension on the door once the other U-bolt is
released.
STEP 4.
Before loosening any bolts or clamps, mark the position of the main door-shaft on the wall bracket.
This will allow the door to be re-installed with correct alignment after the opener is fitted.
STEP 5.
At the side of the door that the opener is to be fitted carefully loosen the door shaft U-clamp,
checking that the spring tension inside the roller door drum is not being released.
STEP 6.
Remove the U-clamp from the
bracket. Do not allow the drum to
fall by sliding the shaft off the end
of the bracket.
