1.1.1 Commissioning

Switch the machine on using the ON/OFF switch. The display illuminates with the text; 'Position drip
tray and press start'. The inlet valve [KW1] opens, the water fl ows via the Pressure reducer [DR], Flow
meter [FL1], Pump [KW2] to the Pressure boiler [H2-3], which is fi lled. Inlet valve [KW1] closes when
Flow meter [FL1] has measured 1.3L. The excess water (approx. 0.2 litres) fl ows via Pressure relief
valve [DV1] to the coffee outlet and drip tray. When the boiler has reached temperature, the machine
is ready for use. Once the commissioning menu has been activated, the control remembers that the
water system has been fi lled. If the machine must be taken out of use for an extended period, the
water system must be drained, 1.1.2 shut down.

1.1.2 Shut down

Activate the shut down menu in the service menu and following the instructions on the display. To
drain the boiler, an Ø 8 mm drain hose must be connected to the boiler supply. To do this, remove the
rear panel of the machine. The control now knows that the water system is empty and on reconnection
will automatically activate the commissioning menu.

1.1.3 No preparation

When no drinks are dispensed by the machine, the pressure in the pressure boiler [H2-3] is main-
tained at 3 bar. Any expansion water from the boiler drains away via valve [DV6] which is switched as
an NO valve. The 3 bar pressure relief valve OVP1 drains any boiler expansion water to the drainage
reservoir.
1.1.4 Coffee preparation
When a coffee is chosen, the coffee grinder measures approx. 7.5 g coffee into the espresso group,
which then turns to the set position (brew). Inlet valve [KW1], coffee valve [DV1] and expansion
valve [DV6] are activated. Note; the expansion valve [DV6] is connected as an NO valve (normally
open). Once activated, the pressure relief valve [OPV1] is closed, as a result of which it is possible to
increase the pressure to 10 bar while the coffee is made. The ground coffee is fi rst (PI-time) moistened
with a small quantity of water (Pre-infusion). This is done at a low water pressure of 2 bar. After a
short soak interval (PI-interval) the water pump [KW2] starts, the pressure is increased to 10 bar and
the actual coffee-making process begins. Depending on how fi ne the coffee is ground and the addition
of water, the coffee-making process takes between 15 and 25 seconds. After the fl ow 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 [fi ll], the coffee residue (pellet) is ejected into
the waste bin.
1.1.5 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 fl ows 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 fl ow 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.
1.1.6 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 fi rst the coffee is made and then the
milk can be added to it. For the preparation of Cappuccino and Latte Macchiato, fi rst 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 specifi ed. For Coffee Milk this is Unit 1-2 (coffee fi rst, then milk), for Cappuccino and
Latte Macchiato this is Unit 2-1 (milk fi rst, then coffee).
1.1.7 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 fl ows via the pressure boiler
[H2-3] and hot water valve [DV4] to the water outlet. After the fl ow 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.
1.1.8 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 [KW2] open. The pressure in the
mains water supply is reduced to 2 bar by the pressure reducer [PR] and fl ows via the external cooler
unit and cold water valve [KW2] to the water outlet. After the fl ow meter [FL1] has measured the set
amount of water, the water dispensing process is stopped. KW1 and KW3 close.
