Unlike standard coffee machines, this
machine has a container for coffee
beans so that they can be freshly
ground for every cup, to benefit fully
from the flavour.
First the ground coffee is moistened
with hot water (pre-brewing), to
develop the aroma. Next, hot water is
forced at high pressure through the
ground coffee. The pre-brewing
process is optional.
To prevent water from remaining in the
pipes, any water left is expelled,
resulting in a little trickle after the coffee
has been dispensed. The coffee is then
ready.
The used coffee grounds are
automatically emptied into the waste
unit. There is no need to remove the
grounds manually after each cup.
The size of cup (max. 250 ml) can be
programmed in so that the correct
amount of coffee is dispensed. If the
cup being used has a smaller capacity
than the programmed cup size,
preparation can be halted at any time
by pressing one of the coffee portion
buttons.
If two cups of coffee or espresso are
required at the same time, the
appropriate coffee portion button must
be pressed twice. The machine will fill
the cups in two stages with a slight
pause in between.
The machine can be programmed to
grind from 6 to 9 grammes of coffee,
depending on the type. The
programmed-in quantity will be the
same for all sizes of cup
(small/espresso, medium coffee, large
coffee). Only the amount of water will
change.
The fineness to which the coffee is
ground can also be programmed in.
The hot water from the hot water spout
is at an ideal temperature for making
tea.
The light can be switched on
independently of operation.
In the interests of safety, the electricity
supply is switched off as soon as the
front of the machine is opened. There is
also a system lock to prevent children
from operating the machine.
The easy to use programming facility
allows, amongst other things, the
language in the display to be altered,
and the water hardness to be
programmed in.
Brief description
11

To ensure that the flavour can develop
fully and be maintained for longer the
machine has an additional function to
automatically rinse and pre-warm the
system. The same function is used to
clean the system and the coffee spouts
after use.
Hot water from the hot water spout can
be used to pre-warm the cups.
The machine can be programmed to
switch to standby mode so it is always
ready for operation but does not
consume unnecessary electricity. This
can be programmed to happen
between 15 minutes and 3 hours after
coffee was last dispensed.
To save time when preparing coffee for
a number of people, the pre-grind
function can be selected, so there is
always a portion of coffee ready.

Rinsing
To remove any coffee grounds from the system the
water piping and brew unit must be rinsed through
every day before the first drink is prepared. If
programme "Rinsing" is set to "On" rinsing will start
automatically when the machine is cold and the
selector switch is set to the "On" position, with or
without lighting. This will warm the brew unit up at
the same time because hot water is used for the
rinse process. An appropriate message will appear
in the display.
If a drink has just been prepared the machine will
still run an automatic rinse programme shortly
before it goes into standby mode.
To prevent water from running into the
drip tray always place an empty cup
under the coffee spouts before making
the first cup of coffee.

forgotten.
^Press ENTER to save this setting, or
turn the selector to "0" to undo the alterations if a
mistake has been made.
This will bring you back from the sub-menu.
Setting the water hardness
For trouble-free operation of the coffee machine,
and to ensure that the descaling reminder appears
in the display at the appropriate time, it is important
to programme in the water hardness. The water
hardness indicates how much calcium is dissolved
in the water. The higher the calcium content, the
harder the water is.
The machine monitors the volume of water passing
through it in conjunction with the hardness of the
water. Less hard water can be allowed to pass
through before descaling than soft water.
The local water authority will be able to tell you the
hardness of water in your area. Alternatively, you
can measure the hardness yourself using the
enclosed test strip:
Programming the machine
17

^Dip the strip in your drinking water for
approximately a second, then shake off any
excess water.
The results will be evident after about 1 minute.
If the water is harder than 7.0 mmol/l or 700 mg/l
(40 °d), limescale will build up more rapidy than
with soft water. Descaling will need to be carried
out more regularly than stated to prevent
limescale damage to the machine.
Use programming option "Water hardness" to
programme in the water hardness.
There are four programmable levels:
Level
(machine) Hardness (local water) °d (German
scale)
mmol/l Water
through-
flow in litres
Hardness 1 1 (soft) 0 - 3 0 - 1.3 approx. 320
Hardness 2 1 (soft) 4 - 7 1.3 - 2.5 approx. 160
Hardness 3 2 (medium) 7 - 14 2.5 - 3.8 approx. 80
Hardness 4 3 (hard)
4 (very hard)
14 - 21
above 21
above
3.8
approx. 40
^Turn the selector anti-clockwise to the
programming position.
The machine is now in programming mode and
will respond according to the symbols shown
under the buttons.
The following will appear in the display:
Press the ebutton to highlight programming
option "Water hardness" with an asterisk.
Programming the machine
18

^Press ENTER to confirm this option.
The sub-menu will appear in the display as
follows:
^Press the ebutton to set the water hardness level
(hardness 1 - hardness 4)
^Press ENTER to save this setting, or
turn the selector to "0" to undo the alterations if a
mistake has been made.
This will bring you back from the sub-menu.
Selecting the temperature for drinks
The machine can be set at different temperatures to
suit varying coffee drinking habits.
Five temperature levels are available for each drink
option. Maximum is the highest temperature,
minimum the lowest.
Not all types of coffee can withstand a
high temperature. Certain types are too
delicate and the froth on top would not
be so good.
^Turn the selector anti-clockwise to the
programming position.
The machine is now in programming mode and
will respond according to the symbols shown
under the buttons.
The following will appear in the display:
Programming the machine
19

^Press the ebutton to highlight programming
option "Temp. L coffee" for large coffee, "Temp.
coffee" for medium coffee or "Temp. S coffee" for
small/espresso coffee with an asterisk.
