Alliance Laundry Systems hc165 User Manual

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)

 

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.

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).
