1 Preparing and using for the first time

Setting up the machine

Filling the bean container

CAUTION

When setting up your Z8, please note the following:

Place the Z8 on a horizontal surface that is not sensitive to

U

water.

Choose a spot for your Z8 which protects the machine against

U

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.

Determining the water
hardness

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.

WARNING

When using the machine for the first time, you can choose whether
you want to operate Z8 with or without the CLARIS Smart filter car­tridge. 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 qual­ity 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.

2 Preparation

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 speciality coffee

U

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

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 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’).

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’).

2 Preparation

Caffè Barista and lungo
Barista

Ground coffee

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 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,
the Z8 stops the operation.

E The desired speciality coffee must be prepared within approx-

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

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

CAUTION

CAUTION

CAUTION

CAUTION

The Z8 builds up deposits of limescale over time and automatically
prompts you to descale it when necessary. The degree of calcifica­tion depends on the hardness of your water.

E If you are using a CLARIS Smart filter cartridge, you will not be

prompted to descale.

If the descaling agent comes into contact with the skin or eyes, this
can cause irritation.

T Avoid contact with the skin or eyes.
T Rinse off the descaling agent with clean water. Should you get

any descaling agent in your eye, see a doctor.

If the wrong descaling agent is used, the machine could be dam­aged and/or traces could be left behind in the water.

T Use only original JURA maintenance products.

If the descaling operation is interrupted, there may be damage to
the machine.

T Allow the descaling programme to run to the end.

If the descaling agent comes into contact with sensitive surfaces
(e.g. marble), damage cannot be ruled out.
