Chapter 3. Machine adjustment and setting up

3.1. Checking the fan rotation sense (reserved to the assistance personel)
Before starting the machine, check for its correct rotation sense by following these instructions:
1. Connect the power cord to a three phase plug plus earthing.
2. Turn the main switch (1) into position 1 (figure 3.2.A page 52).
3. Press START button (5) (figure 3.2.A page 52).
4. Check that the rotation sense of the motor fan (M1) and (M2) shown in the picture corresponds to the sense
indicated by the arrow (figure 3.1.A page 52).
In case the rotating sense is directed counterclockwise, DISCONNECT THE MACHINE and reverse two
of the three phases of the feeding plug (figure 3.1.B page 52).
N.B.: The control of direction of rotation should be carried out each time you change the electrical plug.
