The machine is delivered with hoses with 3/4" connections. These hoses t 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.
International inlet ow capacity per minute (gallons / liters): 4.23 / 16.
US inlet ow capacity per minute (gallons / liters): 5.28 / 20.
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 ow and the number
of machines. It should be sufcient 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.

To comply with the WRAS water regulations: an 'approved' single check valve or
some other no less effective backow prevention device shall be tted at the point of
connection(s) between the supply and the tting (IRN R150).
