Water connection

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.

International inlet flow capacity per minute (gallons / liters): 4.23 / 16.

US inlet flow 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)

Table 1

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

Water drain

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.

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 80L/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.
