3 Preparing and using for the first time
When setting up your ENA, please note the following:
UChoose a spot for your ENA which protects the machine
against overheating. Ensure that the ventilation slots are not
covered.
UPlace the ENA on a horizontal surface that is not sensitive to
water.
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 under flowing water for one second. 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.

Your ENA creates fine, creamy, feather-light milk foam with a perfect
consistency. The most important requirement for frothing milk is a
milk temperature of 4–8°C. We would therefore recommend using
a milk cooler or a milk container.
T Remove the protective cover from the dual spout.
T Connect the milk pipe to the dual spout.
T Connect the other end of the milk pipe to a milk container or a

EYour ENA is equipped with the HP1 milk system.
Your ENA can be connected with your JURA app (J.O.E.®).
Requirement: J.O.E.®is installed on your mobile device. The
optionally available JURA WiFi Connect is inserted into the service
socket of your ENA.

ECoffee tastes best served hot. A cold porcelain cup cools the
beverage – and impairs the taste. We therefore recommend
prewarming the cups. You can purchase a JURA cup warmer
from your specialized dealer.
Touch ZZto call up the Specialty Selection and activate the desired
preselection for your next product:
Specialty Selection Meaning
s– ‘Extra Shot’
(cappuccino, latte
macchiato, flat white)
The product is prepared with two
brewing operations, each with half the
amount of water – for a specialty
coffee with a particularly intense taste.

The product is prepared with ground

EIf you press your preselection briefly, the next product will
be prepared according to your preselection.
EIf you press and hold your preselection (for 2 seconds), the
preselection will be active until you switch off your ENA.
Example:Coffee
T Place a cup under the dual spout.

UCortado

T Place a glass under the dual spout.
T Touch ‘Latte macchiato’.
The preset amount of milk foam flows into the glass.
EThere is a short interval while the hot milk separates from
the milk foam. This allows the typical layers of a latte
macchiato to form.
The preset amount of water for espresso flows into the glass.
E15 minutes after milk preparation, the milk system is
automatically rinsed. 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 7 ‘Maintenance –
Cleaning the milk system’).
For the caffè Barista, the ENA blends the coffee with hot water using
a special preparation method. This results in a full-bodied specialty
coffee which is particularly easy to digest. You can change the
amount of this additional water (see chapter 4 ‘Preparation –
Adjusting the product settings’).
‘Doppio’ is Italian for ‘double’. When you select Espresso doppio,
two espressi are prepared one after the other. The result is an extra
full-bodied and aromatic specialty coffee.
You can choose to use a second coffee variety, for example decaf-
feinated coffee, with the filter funnel for ground coffee.
Basic information about ground coffee:
UNever add more than one level measuring spoon of ground
coffee.
UUse 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.
UIf you did not fill the machine with a sufficient amount of
ground coffee, ‘Not enough ground coffee’ is displayed and the
ENA stops the operation.
UThe desired specialty coffee must be prepared within
approximately one minute after filling with the ground coffee.
Otherwise the ENA stops the operation and is once more ready
for use.

Daily maintenance of the machine and hygiene when handling milk,
coffee and water are key to a perfect coffee result in the cup every
