meter [FL1] has measured the set amount of water, the coffee-making process is stopped. +KW1 and
DV1 close and DV6 opens. While the brewer turns to the start position [fill], the coffee residue (pellet)
is ejected into the waste bin.

3.1.5 Chocolate preparation

For preparing instant, only the water pressure is used.
When a chocolate is chosen, inlet valve [KW1] and mixer valve [DV2] open. The pressure in the mains
water supply is reduced to 2 bar by the pressure reducer [PR] and flows via the pressure boiler [H2-3]
and mixer valve [DV2] to the mixer system [MM2]. The chocolate ingredient is measured by ingredient
motor 4 [IM4]. After the flow meter [FL1] has measured the set amount of water, the water dispensing
process is stopped. KW1 and DV2 close. Shortly thereafter the pressure boiler is brought back up to
the operating pressure of 3 bar by the pump.

3.1.6 Coffee with Milk preparation

The pressure boiler system does not allow two pressure valves to be opened at the same time.
This means that for a combination drink such as Coffee with milk first the coffee is made and then the
milk can be added to it. For the preparation of Cappuccino and Latte Macchiato, first the milk (froth)
and then the coffee (espresso) is prepared. The preparation of the coffee with milk proceeds in the
same way as for the coffee and the chocolate preparation. In the software the required unit sequence
can easily be specified. For Coffee Milk this is Unit 1-2 (coffee first, then milk), for Cappuccino and
Latte Macchiato this is Unit 2-1 (milk first, then coffee).

3.1.7 Hot water preparation

For dispensing hot water, only the water pressure is used.
When hot water is chosen, inlet valve [KW1] and hot water valve [DV4] open. The pressure in the
mains water supply is reduced to 2 bar by the pressure reducer [PR] and flows via the pressure boiler
[H2-3] and hot water valve [DV4] to the water outlet. After the flow meter [FL1] has measured the set
amount of water, the water dispensing process is stopped. KW1 and DV4 close. Shortly thereafter the
pressure boiler is brought back up to the operating pressure of 3 bar by the pump.

3.1.8 Cold water preparation (optional)

For dispensing cold water, only the water pressure is used.
When cold water is chosen, inlet valve [KW1] and cold water valve [KW3] opens, and the 'venting'
valve closes. The pressure in the mains water supply is reduced to 2 bar by the pressure reducer [PR]
and flows via the external cooler unit and cold water valve [KW3] to the water outlet. After the flow
meter [FL1] has measured the set amount of water, the water dispensing process is stopped. KW1
and KW3 close, and the 'venting' valve opens.
