Table 1
The machine is delivered with hoses with 3/4" connections. These hoses fit the water
inlet valves of the machine and the main water inlet taps. All the inlet valves have to be
connected. To ensure the optimal functioning of the water inlet valves, the water pressure
on the inlet should be between 3 and 5 bar (40 and 80 psi). If the pressure is too low, the
cycle time will increase considerably.
In case of boiler fed machines, a minimum of hot water of 90°C - 194°F should be
available per unit. (See Table 1)
