8 FAAC Model S418 Swing Gate Operator
If the size of the pillar or the position of the hinge does
not permit the proper installation of the operator, a niche
will have to be made in the pillar (as indicated in Figure 6)
in order not to change value A (Figure 4). The size of the
niche must be such as to permit an easy installation of the
operator, not limiting its rotation and allowing activation of
the manual release device.

The rear bracket is adjustable to different positions, which
limits modifications necessary to satisfy installation values
A and B.
Figure 7 shows some of the positions that the bracket can
take; all the positions intermediate to those shown may be
obtained.
The positions chosen must permit the assembly of the
bracket using both securing screws.
3.3.1 General Rules for Determining Installation Values
• To obtain opening of the leaf to 90°: A+B=C.
• To obtain opening of the leaf more than 90°: A+B
• Lower A and B values produce higher peripheral leaf
speeds.
• Limit the difference between value A and value B to within
1 ½ inches, greater differences may cause variations in
speed during opening and closing gate movements.
• Maintain a Z value that keeps the operator from striking
the pillar.
• The mechanical stops intervene during the first and final
1 ½ inches of the stroke. Not utilizing the entire operator
stroke could limit the possible adjustments or reduce
them to zero.
3.4 INSTALLING THE OPERATOR
To correctly install the operator, follow the procedure below:
1. Secure the fixed part of the rear bracket in the position
determined previously, using suitable assembly systems.
In the case of iron pillars, the bracket may be welded
directly to the pilaster, see Figures 8 and 9.
During assembly procedures, check that the bracket is
perfectly horizontal using a level.
