sharp edges and ensure that it does not
become trapped�
UNever allow the mains cable to loosely hang
down� The mains cable could pose a tripping
hazard or become damaged�
UProtect the ENA from weather and direct
sunlight�
UOnly connect the ENA to a mains voltage
corresponding to that stated on the rating
plate� The rating plate is located on the under-
side�
UConnect the ENA directly to a domestic power
socket� Using multi-socket adapters or exten-
sion cords may cause overheating�
UDo not use alkaline or alcohol-based cleaning
agents; only use mild cleaning agents and a

damp cloth rather than a wet one, and protect
it from prolonged exposure to water splash�
The ENA must not be cleaned with a jet of
water�
UThe ENA is not suitable for installation on a
surface where a jet of water can be used�
UDo not touch the spouts during operation� Use
the handles provided�
UOptionally, your ENA can be remotely operated
using mobile devices� When preparing a product
or initiating a maintenance programme, make
sure that other people are not put at risk – for
example, through contact with the spouts�

Preparing and using for the first time
Preparing and using for the first time
When setting up your ENA, please note the following:
UPlace the ENA on a horizontal surface that is not sensitive to
water�
UChoose a spot for your ENA 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 under flowing water for one second� Shake
off the water�
T Wait for about 1minute�
T You will then be able to read the degree of water hardness from
the discolouration of the Aquadur® test strip and the descrip-
tion on the packaging�

using the JURA app (J�O�E�®)�
EIf no action is performed on the ENA for 5 minutes, the
symbol display goes dark� However, the ENA remains ready
for use�
Coffee tastes best served hot� A cold porcelain cup cools the bever-
age – and impairs the taste� We therefore recommend prewarming
the cups� You can purchase a JURA cup warmer from your specialised
dealer�
Example:Coffee
T Place a cup under the coffee spout�
T Press the obutton�
The preset amount of water for coffee flows into the cup�
Example:Two espressi

Preparation
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�
Example: Proceed as follows to permanently set the amount of
water for one coffee�
T Place a cup under the coffee spout�
T Press the obutton for about seconds.
The coffee flows into the cup�
T Press any button as soon as there is sufficient coffee in the cup�
Preparation stops� The set amount of water for one coffee is
permanently stored�
EYou can alter this setting at any time by repeating the above
procedure�
You can adjust the grinder to suit the degree of roast of your coffee�
If you adjust the consistency of grind when the grinder is not
operating, the grinding wheel could be damaged�
T Only adjust the consistency of grind when the grinder is
running�
EThe consistency of grind is correct if the coffee flows
regularly from the coffee spout� In addition a fine, thick
crema forms�

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 enough ground coffee,
the £symbol flashes and the ENA stops the operation�
UThe desired speciality coffee must be prepared within approxi-
mately one minute after filling with the ground coffee�
Otherwise the ENA stops the operation and is once more ready
for use�
All speciality coffees with ground coffee are always prepared follow-
ing the same model�
Example:Proceed as follows to prepare one espresso using ground
coffee�
T Place an espresso cup under the coffee spout�
T Keep pressing the sbutton until the £symbol lights up
brightly on the symbol display�
T Open the powder chute for ground coffee�
T Fit the filler funnel for ground coffee�
T Place one level measuring spoon of ground coffee into the filler
funnel�
T Remove the filler funnel and close the cover of the powder
chute�
T Press the ibutton�

Daily operation
Daily operation
T Place a receptacle under the coffee spout�
T Press the On/Off button Q�
EWhen the machine is switched off, the system is only rinsed
if a speciality coffee has been prepared�
The system rinses itself� Your ENA is switched on or off�
Daily maintenance of the machine and hygiene when handling cof-
fee and water are key to a perfect coffee result in the cup every time�
You should therefore change the water daily�
Milk, sparkling mineral water or other liquids can damage the
water tank or the machine�
T Only fill the water tank with fresh, cold water�
T Remove the water tank and rinse it with cold water�
T Fill the water tank with fresh, cold water and reinsert the tank�
Optimal coffee quality depends on many factors� One important
prerequisite is regular maintenance of your ENA� Carry out the fol-
lowing steps:
Maintenance action Daily If necessary Note
Empty the drip tray and coffee grounds
container and rinse with warm water
(The drip tray and coffee grounds
container are dishwasher-safe, but the
insert for the drip tray is not)
x Always empty the coffee
grounds container when the
machine is switched on� This
is the only way of resetting
the coffee grounds counter�
Rinse the water tank x –
Wipe the surface of the machine with a
clean, soft, damp cloth (e�g� microfibre
cloth)
x –
Clean the inside of the water tank with a
brush
