3.1.1 Commissioning
Switch on the machine using the ON/OFF switch. The display illuminates with the text ‘Position the
drip tray and press start’. The inlet valve [KW1] opens and the water flows via the pressure reducer
[PR], flow meter [FL1] and pump [KW2] to the pressure boiler [H2-3], which is filled. The inlet valve
[KW1] closes when the flow meter [FL1] has measured 1.3 litres. The excess water (approximately 0.2
litres) flows via the pressure relief valve [DV1] to the coffee outlet and drip tray. When the boiler has
reached the set temperature, the machine is ready for use. Once the commissioning menu has been
activated, the control remembers that the water system has been filled. If the machine is taken out of
use for an extended period, the water system must be drained. See chapter 7 Shut down.

3.1.2 Shut down
Activate the shut down menu in the service menu and follow the instructions on the display. To drain
the boiler, an drain plug must be removed from the boiler drain hose. To do this, remove the back
panel of the machine. The control now knows that the water system is empty and reconnection will
automatically activate the commissioning menu.

3.1.3 No preparation
When no drinks are dispensed by the machine, the pressure in the pressure boiler [H2-3] is
maintained at 3 bar. Any expansion water from the boiler drains away via the valve [DV6], which is set
as a NO (normally open) valve. The 3-bar overpressure relief valve OVP1 drains any boiler expansion
water to the drainage reservoir.
