Setting up the machine

Filling the bean container

CAUTION

Visit us on the Internet. You can download short operating instruc­tions for your machine from the JURA website (www.jura.com). You

will also find interesting and up-to-date information on your D4 and
on every aspect of coffee.

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

When setting up your D4, please note the following:

Place the D4 on a horizontal surface that is not sensitive to

U

water.

Choose a spot for your D4 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.

Determining the water
hardness

10

T Open the bean container cover and remove the aroma pre-

servation cover.

T Remove any dirt or foreign objects from inside the bean

container.

T Fill the bean container with coffee beans, then close the

aroma preservation cover and the bean container 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.

First-time use

1 Preparing and using for the first time

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.

2 Preparation

2 Preparation

Basic information about preparing drinks:

Before and during the grinding operation you can select the

U

coffee strength for the speciality coffees espresso < and

coffee >: ‘mild’ (;), ‘normal’ (:), ‘strong’ (_).

Double product: To prepare two speciality coffees, touch the

U

Double Product symbol ‘2x’ before preparation. Then choose

between espresso < and coffee >. When you prepare

double products, two brewing operations take place one after

the other.

While a speciality coffee is being prepared, you can stop pre-

U

paration at any time. Simply touch the symbol for the speci-

ality coffee in question.

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.

Espresso and coffee

Two espressi and two
coffees

Espresso and coffee are both prepared following this model.

T Touch the Coffee symbol >.

Preparation starts. The preset amount of water for coffee
flows into the cup.
Preparation stops automatically. Your D4 is once more ready
for use.

When you prepare two speciality coffees at once, the amount of
water selected for the single product is used for each cup.

The preparation of twoespressi and twocoffees follows this same
model.

Example:Proceed as follows to prepare two espressi.
Precondition:Your D4 is ready for use.

cup size

Adjusting the grinder

It is easy to make permanent settings for the amount of water for all
speciality coffees according to the cup size. Adjust the amount once
as shown in the following example. Every time you prepare a drink
in the future, this amount of water will be dispensed.

The process for permanently adapting the amount of water to the
cup size is the same for all speciality coffees.

Basic information about ground coffee:

Never add more than two level measuring spoons of ground

U

coffee.

Use ground coffee which is not ground too finely. Very fine

U

coffee can block up the system so that the coffee only comes

out in drips.

If you did not fill the machine with enough ground coffee, the

U

D4 stops the operation and is then ready for use again.

The desired speciality coffee must be prepared within approx-

U

imately one minute after filling with the ground coffee. Oth-

erwise the D4 stops the operation and is once more ready for
