1 Preparing and using for the first time

JURA on the Internet

Operation with touchscreen display and Rotary Switch

Visit us on the Internet (www.jura.com). You will find interesting and up-to-date information on your Z8 and on every aspect of coffee.

If you need assistance with using your machine, you can find this at www.jura.com/service.

Your Z8 features a touchscreen display. There are two ways of operating the touch display:

Tou ch

Touch the display with your finger, for example to start coffee preparation or undertake various settings in programming mode.

Slide

Move your finger across the display from left to right or from top to bottom (or vice versa). For example, you can select one of the specialty coffees in the product selector view or switch between program items in programming mode.

Programming with Rotary Switch: Also use the Rotary Switch. As soon as you turn it, the product selector view is displayed. Also navigate through the program items in programming mode and change various settings.

1 Preparing and using for the first time

Setting up the machine

Filling the bean container

NOTICE

When setting up your Z8, please note the following:

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

water. 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.

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

First-time use

J WARNING

Degrees of general hardness (°dGH)

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.

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’).

Connecting milk

Connect accessory (with wireless connection)

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.

Your Z8 is equipped with the JURA Smart Connect. This allows you to connect the machine wirelessly to a compatible JURA accessory (e.g. the Cool Control Wireless milk cooler).

Precondition:The start screen is displayed.

T Touch ‘P’.

‘Machine settings’

T Touch ‘Machine settings’.

‘Switch off after’

T Move your finger across the display until ‘Connect

accessory’ is displayed in the center.

T Touch ‘Connect accessory’.

‘Connect accessory’

T Now follow the instructions on the display to connect the

accessory to the Z8.

2 Preparation

J WARNING

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:

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. 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. 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’).
