Installation foresees the following operations:
a) Align two units side by side. Before pushing the
two units completely together, make sure that
the lower joining plate of the right-hand unit is in
the upper position.
b) Screw the joining plate and the unit plates
together (with 6 Torx M6x12 screws) so that they
are fully tightened. Insert a bolt (M8x20 round-
headed with square neck) with a nut (M8
hexagonal nut with flange) (figure 45) to tighten
the units and the joining plate.
