Site Requirements
Electrical Power Supply
The opener is for 220-240 Volts AC - 50 Hz. There must be an earthed power point within 1.6
metres of the mounting position.
Garage Door
This opener is designed for a residential overhead garage door up to 6 m wide, either sectional or
one-piece tilting. Using the standard length pole and chain it is suitable for door heights up to 2.2
m. Alternative poles and chains are available to suit door heights up to 2.4 m and 3.1 m. Contact
Merlin for solutions to suit door heights up to 4.5 m.
Check that it is possible to raise the door by hand through the full height of the opening. The door
should operate smoothly, lifting up and down without the door or door mechanism binding. The door
must not jam in the tracks.
A properly balanced tilt door will stop of its own accord at about the two thirds closed position.
(Springs may need adjustment accordingly).
For one piece tilt doors over 4.5 m in width built out of cedar or ply it is advisable to use the smaller
15 tooth sprocket.
A properly sprung sectional door will either close of its own accord for the last 500mm of its travel
or it will require a very light added force. If the door springs back, it is advisable to have the spring
tension adjusted. Springs can only be adjusted safely by a trained professional.
If in doubt about whether the door is suitable for automation consult Merlin.
Tilt door clearances
The opener has been designed to fit most existing doors. The minimum installation clearance from
the garage ceiling to the top edge of the door during any part of the door’s travel is 100mm.
The header bracket is to fit as close as practical above the top of the door, in the centre.
The door bracket is to fit at the highest possible point of the door, in the centre. The bracket may be
fixed vertically or horizontally to suit. A solid fixing point is required.
The overall length of the opener when assembled depends on the length of pole fitted. The overall
length is 400mm more than the length of the pole.
Clear space of around 600mm is required behind the fully open door.
Sectional door clearance guidelines
For sectional doors using torsion springs the minimum allowable height from the top of the closed
door to the ceiling is 200mm.
For sectional doors using tension springs the minimum allowable height from the top of the closed
door to the ceiling is 280mm.
The header bracket is to fit 200-300mm above the top of the door at the centre or directly above
the torsion bar.
The door bracket is to fit in line with the top rollers in the top panel. It may fit vertically or horizontally.
A solid fixing point is required.
The overall length of the opener when assembled depends on the length of pole fitted. The overall
length is 400mm more than the length of the pole.
Clear space of around 600mm is required behind the fully open door.
