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.
T Never use a machine which has a defective power cord.

Basic information about preparing drinks:

During the grinding operation you can change the coffee

U

strength of single products: To do this, move your finger
across the display or turn the Rotary Switch.
During preparation you can change the preset amounts (e.g.

U

amount of water or milk foam). To do this, move your finger
across the display or turn the Rotary Switch.
You can stop the machine at any time while a specialty coffee

U

or hot water is being prepared. To do this, press the ‘Cancel’
button or the Rotary Switch.

E The water volume is given as standard in ‘oz’. You can change

this setting to ‘ml’ in programming mode (see Chapter 4

16

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’).

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.

E 15 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’).

Caffè Barista and
Americano

Ground coffee

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.

E Never add more than two level measuring spoons of ground

coffee.

E Use 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.

E If 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.

19

2 Preparation

E The desired specialty coffee must be prepared within

approximately one minute after filling with the ground
coffee. Otherwise the Z8 stops the operation and is once
more ready for use.

All specialty coffees with ground coffee are always prepared
following the same model.
