Preparatory steps
3.5 PREPARATION OF THE REAR MOUNTING
Estimate B measurement for securing the operator to the
installation (Fig.8 and Table 3).
With this B value, calculate the length (L) for the rear
mounting as follows: L = B-Y. Assemble the two plates that
comprise the mounting to reach the length calculated (see
example in Fig.9).
The possible mounting assemblies are shown in Fig.10 and each
one is noted with its corresponding length.
Secure the plates with the screw and nut pairs supplied.
Next, use a hacksaw to cut the operator securing plate
just behind the hole used.

3.6 MAKING A NICHE ON THE MASONRY PILLAR FOR REAR MOUNTING

estimate the niche size.

the mounting (L) for your installation, you should decide on
the assembly position of the two plates (always use the x
hole + one of the 5 arranged in an arc) and choose the hole
for securing the operator from one the 2 Y holes provided.
