Inlet valve KW1 [1001161]
Opens and closes the water supply, 24 Vdc coil closure.
Pressure reducer DR [1000702]
Reduces the water supply pressure to 2 bar.
The water pressure is not adjustable.
Pay attention for the ow direction!
Flow meter FL [1000530]
Measures the supplied quantity of water using rotating magnets
and a bi-polar Hall sensor. Pay attention for the ow direction!
Solid State Relais (SSR) [02799]
The heating element is controlled by a solid state relay.
Pay attention for the polarity of the 24Vdc side!
Pump KW2 [1000696]
Non-return valve [1000748]
Rotary membrane pump; increases the water supply pressure to
an espresso pressure of 10 bar.
The rotating membrane cells increase the outlet water pressure.
An internal bypass valve pumps the water round in the pump
housing if no pressure decrease occurs.
See Section 5.7 Check / set the pump pressure.
