Replacing the electrical heaters
WARNING! Before replacing the electrical heaters, disconnect the power supply from the unit. Make sure
that it is not possible for the power to be turned on again while they are being replaced.
WARNING! The heaters must only be replaced by a qualied electrician.
The total capacity of the electrical heaters is subdivided into
more elements, each with a capacity equal to 2 or 3 kW
based on the size of the unit.
The signicance of the colours of the wires present on each
element is as follows:
- BLACK wire = element with the lowest power (0,7 or 1kW
based on the size of the unit);
- WHITE wire = element with the highest power (1,3 or 2kW
based on the size of the unit);
- RED wire = standard.
The wires of each element are connected to the CR1 and
CR2 connectors on the electrical panel in such a way as
to balance the load across the phases and create three
stages of heating (refer to the electric diagram on the side
of the machine).
