8) Lift the sliding guide bringing the rear connection to the
same level as the front one, or until reaching the same
angle as the door horizontal rail. For direct fixing to the
ceiling, go to point 12, after modifying the rear connection
as indicated in par. 6.2.
9) Measure the distance between ceiling and the centre
distance of the rear connection fixing nuts.
10) Bend the brackets (supplied) to the measurement made
(measure from the centre of the first slot on the bracket).
11) Fit the brackets on the rear connection and reposition the
sliding guide (fig. 14).
12) Mark the fixing points on the ceiling, drill (taking care to
protect the sliding guide), position the front fixing bracket
of the operator (fig. 9 ref. C and fig. 14) and complete
guide installation.
13) If using a "two pieces sliding guide" with central connection
(fig. 15 ref. A) or the central support for single rail (fig. 15
ref. B - optional), carry out ceiling fixing using the special
brackets, proceeding as described in steps 9,10 and 12
(fig. 15).
7.2. CONNECTION ON DOOR
1) Assemble the connection bracket with the carriage bar
(fig. 16).
If using the outside release device, position the
connection bracket on the door so that the release wire
loop is turned towards the left side of the door (fig. 16
and 17).
2) Close the door and bring the carriage near it.
3) Position the connection bracket on the door centred with
the middle.
4) Check that the distance between centres of the door
connection and front connection bracket fixing holes is not
more than 20 cm (fig. 17). For correct working of the
automatic system avoid arm angles of more than 30° with
respect to the sliding guide.
If using the curved arm for sectional doors (optional) carry
out assembly with the straight arm of the carriage as
indicated in fig. 18. To improve the efficiency of the
anticrushing system it is advisable to fix the connection
bracket on the sectional door in the lowest position possible,
but not more than 40 cm from the front connection of the
operator.
5) Mark, drill and fix the connection bracket to the door.
