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. To ensure the optimal
functioning of the water inlet valves, the water pressure on the inlet should be between
2.07 and 5.86 bar (30 and 85 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)

Water connection
❏ The diameter of the main drain should be adapted to the water flow and the number
of machines. It should be sufficient to handle at least 80 l/min - 21.13 gal./min per
machine.
❏ It is necessary to connect the main drain at least on one side to an open air-brake to
allow ventilation.
The machine is equipped with a drain valve with 2" outer diameter (50 mm). This drain
valve should be connected to the drain by means of the drain elbow which is delivered
with the machine.
