After placing and securing the machine in its final location, carry out the
following important control operations in the given sequence:
1) check the mains voltage against the voltage shown on the machine plate
(see par. 2.3) corresponds to the laboratory voltage; if the voltage is incorrect,
do not make electrical connections under any circumstances. Contact the
supplier or manufacturer immediately.
2) Make sure the machine rotates in the right direction; to do this, after
plugging in, carry out the following procedures:
- s w itch th e m a in s w itc h ref. 8 Photo 1 o n p a g e 8 to p o sitio n 1 ;
- s e t th e m in im u m tim e o n th e tim e r ref. 7 Fig. 1 o n p a g e 8 ;
- p re ss th e sta rt b u tto n fo r th e 1 st sp e e d ref. 1 Fig. 1;
From the front of the machine, as shown in Photo 2 on page 10, the spiral
tool must rotate clockwise.
If this is not the case switch off, using the pushbutton ref. 3 Fig. 1; then switch
the main switch ref. 8 Photo 1 from position 1 to position 0, unplug, unscrew
the plug as shown in the figure and invert the black and brown wires.
If the connection is three-phase + n earth, there are two black wires.
In this case, either black wire may be switched over with the brown wire; if the
cable is three-phase + earth there is only one black wire so there is no
problem in switching over the wires.
Close the plug with the screws, as shown in the above illustration, and plug
back into the mains socket.
Re-check, repeating the sequence given at point 2. of this paragraph.
Rotation should now be clockwise.
Caution!
Never disconnect the yellow-green (earth) and/or blue wires or
change their positions.
