be started, brought to the nominal working condi-
tion and left for 30 minutes in the "ready to operate"

emptied of the rst water introduced in the whole hy-
draulic circuit, to eliminate possible initial impurities;
• then, the appliance must be loaded and brought to
the nominal working conditions;

circuit;

Qualied Technician must renew 100% of the water contained in
the hydraulic circuit, as indicated above.
• Before using the machine, run dry deliveries with the lter
holder attached for a few seconds to release any air which may
be in the circuit, so that the dispensing groups are completely
