2 For your safety

Comply with the instructions for use

Proper use

Before using the machine, read these instructions for use thoroughly and completely and comply with the instructions they contain� Keep these instructions for use close to the machine and pass them on to the next user�

Failure to observe the instructions for use may result in serious injuries or damage to property� Safety information is therefore indicated as follows:

J

WARNING

Indicates circumstances that may result in serious injuries or death�

J

CAUTION

Indicates circumstances that may result in minor injuries�

CAUTION Indicates circumstances that may

result in damage to property�

The machine is intended for private domestic use� It is intended only for coffee and hot water preparation� Use for any other purpose will be deemed improper�

User limitations

6

People, including children, who

do not have the physical, sensory or mental

U

capabilities to use the machine safely or are inexperienced or lack knowledge

U

must be supervised by a responsible person when using it, or must be instructed in how to use it correctly�

2 For your safety

When using the CLARIS Smart filter cartridge or a JURA WiFi Connect, wireless connections are established� Specific details on the frequency band used and the maximum transmission power can be found in the ‘Technical data’ section�

Use by children

What to do in the event of damage

Children must be able to recognise and understand the potential dangers arising from incorrect use:

Keep children under the age of 8 away from

U

the machine, or supervise them constantly� Children aged 8 and over may only operate

U

the machine without supervision if they have been instructed in how to use it safely� Children may not clean or service the machine

U

unless supervised by a responsible person� Do not allow children to play with the machine�

U

Never use a damaged machine or mains cable. This could result in fatal electric shock.

In the event of signs of damage, disconnect the

U

machine from the mains� To do this, first switch the E4 off with the On/Off button Q� Only then should you remove the mains plug from the power socket� Replace a damaged plug-in mains cable with

U

an original JURA mains cable� Unsuitable mains cables may result in consequential damage� Only permit authorised JURA service centres to

U

carry out repairs to the machine and the permanently connected mains cable. Unsuitable repairs may result in consequential damage�

7

2 For your safety

Preventing damage

To avoid damage to the machine and the mains cable:

Do not use the E4 and the mains cable near

U

hot surfaces� Do not allow the mains cable to rub against

U

sharp edges and ensure that it does not become trapped� Never allow the mains cable to loosely hang

U

down� The mains cable could pose a tripping hazard or become damaged� Protect the E4 from weather and direct sunlight�

U

Only connect the E4 to a mains voltage corre-

U

sponding to that stated on the rating plate� The rating plate is located on the underside� Connect the E4 directly to a domestic power

U

socket� Using multi-socket adapters or extension cords may cause overheating� Do not use alkaline or alcohol-based cleaning

U

agents; only use mild cleaning agents and a soft cloth� Do not use any coffee beans treated with

U

additives or caramelised coffee beans� Only fill the water tank with fresh, cold,

U

non-carbonated water� Switch the machine off with the On/Off

U

button Q if you are going to be absent for a longer period of time and remove the mains plug from the power socket� Only use original JURA maintenance products�

U

Use of products that are not explicitly recommended by JURA could damage your E4�

8

2 For your safety

Danger of electric shock

Danger of burns, scalding and injury

Water conducts electricity. Do not bring water and electricity into contact with one another:

Never touch the mains plug with wet hands�

U

Do not immerse the E4 and/or mains cable in

U

water� Do not put the E4 or any individual parts in the

U

dishwasher� Before cleaning, switch the E4 off with the

U

On/Off button Q� Always wipe the E4 with a damp cloth rather than a wet one, and protect it from prolonged exposure to water splash� The E4 must not be cleaned with a jet of water� The E4 is not suitable for installation on a

U

surface where a jet of water can be used�

Do not touch the spouts during operation� Use

U

the handles provided� Optionally, your E4 can be remotely operated

U

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�

9

3 Preparing and using for the first time

Setting up the machine

Filling the bean container

CAUTION

When setting up your E4, please note the following:

Place the E4 on a horizontal surface that is not sensitive to

U

wa ter� Choose a spot for your E4 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

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

10

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 discolouration of the Aquadur® test strip and the description on the packaging�

4 Preparation

Adjusting the grinder

CAUTION

wq

Ground coffee

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 grinder adjustment switch could be damaged�

T

 Only adjust the consistency of grind when the grinder is

running�

E The consistency of grind is correct if the coffee flows

regularly from the coffee spout� In addition a fine, thick crema forms�

Grinder adjustment switch

You can choose to use a second coffee variety, for example decaffeinated coffee, with the filter funnel for ground coffee�

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,

U

the

£ symbol flashes and the E4 stops the operation�

The desired speciality coffee must be prepared within approxi-

U

mately one minute after filling with the ground coffee� Otherwise the E4 stops the operation and is once more ready for use�

The E4 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� However, should you need to descale the E4, first switch the machine to descaling mode (see section 7 “Maintenance – Switching the machine from filter mode to descaling mode”)�
