10.5.2 New Filter dial
Until now, the loading circuit was drained as described below:
For some machines it is necessary to disconnect the drain pipe from the back panel, positioning it as low
down as possible to drain any remaining water from the inside of the drain circuit.
In other machines, there is a small hatch at the bottom of the front panel, from which it is possible to access
the filter dial. Close to this is a small pipe that can be used to drain the water, after the plug has been
removed from it.
For machines manufactured with the new filter dial: open the hatch at the bottom of the front panel, and the
filter dial will appear as shown in fig. 1.
To drain the water, simply:
Press the two tabs that lock the plug closing lever, fig. 2.
Simultaneously remove the top part of the lever as indicated by the yellow arrow fig. 3.
Position the closing lever as shown in fig. 4.
