Installing the opener
WARNING Garage doors are under great spring tension. Do not remove the springs.
Merlin does not accept responsibility for damage or injury resulting from installing
this opener. Please read this manual fully before attempting installation.
STEP 1:
Check that there is a power point available and that there is adequate clearance to mount the
opener onto the door. Check that the door is in good mechani-
cal condition, correctly balanced and opens properly.
STEP 2: Close the door.
STEP 3: Mark the centre line of the door using a tape meas-
ure and pencil. Mark on the header above the door and mark
the door itself at the top edges.
STEP 4: Check the installation height of the opener. Slowly
open the door and observe the point at which the top edge of
the door is closest to the ceiling. Measure the height of the top
edge of the door from the floor of the garage at this point. You
may have to clamp the door in position or use blocks to hold it.
STEP 5: Close the door again and mark this maximum door
height onto the header above the top edge of the door. (On tilt
doors with tracks, this maximum height might be as low as the
top edge of the closed door.) If a sectional door torsion bar or
spring is in the way, mark the next clear space on the wall above.
Extend the door centre line up to intersect with the new height line.
Additional setup for trackless tilt doors (jamb fittings) only
Mark a horizontal line 300mm above this maximum door height line. If there is insufficient space
above to allow the line to be 300mm above the maximum height, then draw the line 80mm below
the ceiling. Extend the door centre line up to intersect with the new height line.
STEP 6: Fit the header bracket to the header above
the top of the door. The header bracket must be at-
tached to a rigid part of the garage such as a beam,
with the bottom edge of the bracket no lower than
the height line that has just been marked. The cen-
tre line of the door must align with the centre line of
the header bracket.
STEP 7: Place the opener assembly in the centre
of the garage floor, resting on its styrofoam or card-
board packing to protect the power head from
scratching by the garage floor.
