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
container.
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 discoloration of the Aquadur® test strip and the
description on the packaging.

When using the machine for the first time, you can choose whether
you want to operate Z8 with or without the CLEARYL Smart filter
cartridge. As well as limescale, the filter cartridge filters many other
substances that impair aroma and flavor out of the water. These
substances may negatively affect the coffee. To enjoy the best
quality coffee at all times, we recommend that you use CLEARYL
Smart.
If the machine is operated with a defective power cord, there is a
danger of potentially fatal electric shock.
T Never use a machine which is damaged.

Your Z8 creates fine, creamy, feather-light milk foam with a perfect
consistency. The most important requirement for frothing milk is
a milk temperature of 39–46 °F (4–8 °C). We would therefore
recommend using a milk cooler or a vacuum milk container.
TConnect the milk pipe to the dual spout.
TConnect the other end of the milk pipe to a milk container
or a milk cooler.

Hot coffee, hot steam and hot water can cause scalding. Scalding is
a serious burn.
T Use extreme care when handling hot liquid or steam.
T Allow liquid to cool down before drinking.
T In the event of scalding, rinse affected area with cold water
and seek medical attention.
T Keep children AWAY.
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 specialty coffee
or hot water is being prepared. To do this, press the ‘Cancel’
button or the Rotary Switch.
EThe water volume is given as standard in ‘oz’. You can change
this setting to ‘ml’ in programming mode (see Chapter 4
‘Permanent settings in programming mode – Unit for amount
of water’).
Coffee tastes best served hot. A cold porcelain cup cools the
beverage – 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
specialized dealer.
You can make permanent settings for all products in programming
mode (see Chapter 4 ‘Permanent settings in programming mode –
Adjusting the product settings’).

2 Preparation
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
automatically. 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
properly, you must clean it daily (see Chapter 5 ‘Maintenance –
Cleaning the milk system’).
For the ‘Caffè Barista’ and ‘Americano’, the Z8 blends the coffee with
hot water using a special preparation method. This results in a
full-bodied specialty 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
decaffeinated 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.
