7.5. Wiring diagram
See Annex C
7.6. Adapting to different power supply voltages
Attention! To adapt the appliance to function with supply voltages
different from those shown on the label indicating its initial configuration, it
is necessary to carry out three modifications:
1. resistor rewiring
2. rewire the supply to the control panel
3. Remove the old label and apply a new one
Carry out all three modifications with care and attention. Only in this
way can the appliance be considered safe
7.6.1. Resistor rewiring
Remove the plug from the mains supply switchgear. Remove the
protective housing from the power panel. Disconnect all the resistor wires
from the contactors and reconnect them according to the voltage (see
electrical diagrams annex C).
7.6.2. Applying the new label
Remove the old label from the plate at the back of the appliance. Clean
the surface with a cloth and a dab of petrol and apply the new label.
