1 Preparing and using for the first time
When setting up your Z8, please note the following:
UPlace the Z8 on a horizontal surface that is not sensitive to
water.
UChoose a spot for your Z8 which protects the machine against
overheating. Ensure that the ventilation slots are not covered.
The bean container has an aroma preservation cover. This will ensure
that your coffee beans retain their aroma for longer.
Coffee beans which have been treated with additives (e.g. sugar),
ground coffee or freeze-dried coffee will damage the grinder.
T Only use roasted, untreated coffee beans to fill the bean con-
tainer.
TRemove the aroma preservation cover.
TRemove any dirt or foreign objects from inside the bean
container.
TFill the bean container with coffee beans and close the
aroma preservation cover.
When you use the machine for the first time, you must set the water
hardness. If you do not know the hardness of your water, you can
find this out first. Use the Aquadur® test strips supplied with the
machine.
THold the test strip briefly (for 1second) under flowing water.
Shake off the water.
TWait for about 1minute.
TYou will then be able to read the degree of water hardness
from the discolouration of the Aquadur® test strip and the
description on the packaging.

1 Preparing and using for the first time
When using the machine for the first time, you can choose whether
you want to operate Z8 with or without the CLARIS Smart filter car-
tridge. As well as limescale, the filter cartridge filters many other
substances that impair aroma and flavour out of the water. These
substances may negatively affect the coffee. To enjoy the best qual-
ity coffee at all times, we recommend that you use CLARIS Smart.
If the machine is operated with a defective mains cable, there is a
danger of potentially fatal electric shock.
T Never use a machine which is damaged or has a defective
mains cable.
Precondition:The bean container has been filled.
TInsert the mains plug into a power socket.
TPress the On/Off button Qto switch the Z8 on.

Basic information about preparing drinks:
UDuring the grinding operation you can change the coffee
strength of single products: To do this, move your finger
across the display or turn the Rotary Switch.
UDuring preparation you can change the preset amounts (e.g.
amount of water or milk foam). To do this, move your finger
across the display or turn the Rotary Switch.
UYou can stop the machine at any time while a speciality coffee
or hot water is being prepared. To do this, press the ‘Cancel’
button or the Rotary Switch.
Coffee tastes best served hot. A cold porcelain cup cools the bever-
age – and impairs the taste. We therefore recommend prewarming
the cups. The full coffee aroma can develop only in prewarmed cups.
You can purchase a JURA cup warmer from your specialised dealer.
You can make permanent settings for all products in programming
mode (see Chapter 4 ‘Permanent settings in programming mode –
Adjusting the product settings’).
The Z8 offers various ways of preparing a speciality coffee, milk or
hot water.
Preparation using the start screen: Simply touch the desired
product. The following products are displayed as standard on
the start screen:
Page ‘1/2’ Page ‘2/2’
‘Ristretto’
‘Espresso’
‘Coffee’
‘Caffè Barista’
‘Macchiato’
‘Cappuccino’

bring the desired product into focus. Touch the product or press the
Rotary Switch to start preparation. The following additional prod-
ucts are shown in the product selector view:
U‘2x Ristretto’
U‘2x Espresso’
U‘2x Coffee’
U‘2x Lungo Barista’
U‘2x Caffè Barista’
EThe product selector view disappears automatically after
10seconds if no preparation is started.
EThe last product selected always appears first in the product
selector view.
EYou can move any of the standard products programmed in
your Z8 to your preferred position on the start screen and
make it one of your favourites. You can duplicate and person-
alise your favourite speciality coffees by giving them a new
product name and individual settings (e.g. amount and coffee
strength) (see Chapter 4 ‘Permanent settings in programming
mode – Product settings’). Please note that the descriptions
provided in the following sections always refer to the default

speciality coffees with milk at the touch of a button. There is no need
to move the glass or cup.
Example:Proceed as follows to prepare one latte macchiato.
Precondition:The start screen is displayed. Milk is connected to the
dual spout.
TPlace a glass under the dual spout.
TTouch ‘Latte macchiato’.
‘Latte macchiato’, the preset amounts of milk and milk foam
flow into the glass.
EThere is a short interval while the hot milk separates from the
milk foam. This allows the typical layers of a latte macchiato
to form.
Coffee preparation starts. The preset amount of water for
espresso flows into the glass. Preparation stops automati-
cally. Your Z8 is once more ready for use.
E15 minutes after preparation, the milk system is automatically
rinsed (see Chapter 5 ‘Maintenance – Automatic milk system
rinsing’). Therefore always place a receptacle under the dual
spout after preparing milk.
To ensure that the milk system in the dual spout always works prop-
erly, you must clean it daily (see Chapter 5 ‘Maintenance – Cleaning
the milk system’).

2 Preparation
For the ‘caffè Barista’ and ‘lungo Barista’, the Z8 blends the coffee
with hot water using a special preparation method. This results in a
full-bodied speciality coffee which is particularly light and digestible.
You can change the amount of this additional water (see Chapter 4
‘Permanent settings in programming mode – Adjusting the product
settings’).
You can choose to use a second coffee variety, for example decaf-
feinated coffee, with the filter funnel for ground coffee.
ENever add more than two level measuring spoons of ground
coffee.
EUse ground coffee which is not ground too finely. Very fine
coffee can block up the system so that the coffee only comes
out in drips.
EIf you did not fill the machine with a sufficient amount of
ground coffee, ‘Not enough ground coffee’ is displayed and
the Z8 stops the operation.
EThe desired speciality coffee must be prepared within approx-
imately one minute after filling with the ground coffee. Oth-
erwise the Z8 stops the operation and is once more ready for
use.
All speciality coffees with ground coffee are always prepared follow-
ing the same model.
Example:Proceed as follows to prepare one espresso using ground
coffee.
Precondition:The start screen is displayed.
TPlace an espresso cup under the coffee spout.
TOpen the powder chute cover.

TTouch ‘Espresso’.
Preparation starts. ‘Espresso’appears and the preset amount
of water for espresso flows into the cup.
Preparation stops automatically. Your Z8 is once more ready
for use.
You can adjust the grinder on a continuous scale to suit the degree
of roast of your coffee.
If you adjust the consistency of grind when the grinder is not oper-
ating, the grinder adjustment switch could be damaged.
T Only adjust the consistency of grind when the grinder is run-
ning.
