The machine is in operation and one user works with a standard nozzle of size 006
corresponding to 17.3 l/min. (1038 l/h) or the water volume of one pump.
The water temperature is set at cold, meaning that only the solenoid valve for cold water
is activated when there is a requirement for water.

Pump P2 is in operation. The pressure in the system is 160 bar. The water is drawn from
the tank and the pump pumps it through the non-return valve into the central pipe,
through the main non-return valve and into the system. On the display the two lights of
the pressure switches (B1) and (B2) are on, and the light of the pressure relief valve (Y3)
signals that the valve is closed.
(B6) indicates that the level in the water tank is not so low that more more water is
required. The system is stable.
