• Installation, initial start-up and maintenance of the appliance must be carried out by
qualified personnel only. All hydraulic and electrical connections must be carried out in
compliance with current safety norms. The manufacturer accepts no responsibility for
malfunctions arising from incorrect connection of the appliance. When installing, ensure

• The appliance is designed for connection to the cold or hot water supply (max. 50 55°C)
at a mains pressure with the valve open as shown in Table 2-1 and a minimum output of
10 litres/min. If pressure exceeds the maximum, fit a pressure reducer. If pressure is
lower than the minimum, fit a pressure booster pump of max. 0.5 HP, with an output of
20 litres/min. and a head of 15÷20 metres. Pressure must be measured at the solenoid
valve inlet (see fig. 2-4). The water pipes must have an internal diameter of at least
16/18 mm (see fig. 2-5). Connect the appliance water supply pipe to a cut-out tap (B),
preferably placed close to the appliance, fitting the special filter provided (B1)
(see fig. 2-2). We recommend fitting a water softener (C) (not provided) upstream from
the machine solenoid valve (see fig.2-3).
