Keeping the control unit in line with
the top of the garage door, place
a spirit level perpendicular to the
ceiling, and line it up with the center
of the drive rail hanger bolt on the
side of the drive rail hanger. Make a
mark on the ceiling, and repeat this
for the other side of the drive rail
hanger.
Ensure that the drive rail
hanger bracket is positioned
directly under a
strong
structural member of the
ceiling. If it is not, move
it along the drive rail to
a suitable position before
marking it off on the ceiling.
We recommend that the
maximum cantilever
distance between the
hanger bracket and the
front edge of the control
unit does not exceed
300mm.
