1 Preparing and using for the first time
When setting up your Z8, please note the following:
U
Place the Z8 on a horizontal surface that is not sensitive to
water.
U
Choose 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 1second) under flowing water.
Shake off the water.
T Wait for about 1minute.
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.

Basic information about preparing drinks:
U
During 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.
U
During 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.
U
You 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.
E The 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’).

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.
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.
