6.4 Starting up of the unit
The distributor is provided with a connection cable for connection
to the mains water supply (fig.6.9) and a switch which cuts off
the power from all users each time that it is operated (fig.6.10).
Should it be necessary to operate inside the distributor for any
ordinary or special maintenance operates, it is necessary to isola-
te the user appliances by activating the switch (fig.6.11), bearing
in mind that with the electrical connection engaged, the power
terminals are live.
Each time the distributor is switched on a diagnosis cycle is
performed in order to verify the position of the mobile parts and
the presence of water and of some products.
