Installation
Before attaching the rail to the motor, unscrew the nuts on each
support bracket (D-6mm). Attach the guide to the motor, fix it
with the brackets (Fig. 4-E), and tighten the nuts firmly.
Fix the rail to the frame or ceiling using the supporting brackets provided
(Fig. 5), and leaving a 30mm minimum distance between the highest point
the door will reach during its motion and the operation rail (Fig. 6). Make
the correct measurements to attach the operator-rail assembly to the
ceiling with the supporting brackets (Fig. 4-F), shorten them if necessary.
Notice
Ensure that the operator is anchored in concrete and not in plaster.
