Important information
Important information
Proper use
For your safety
J
The machine is designed and intended for private
domestic use. It should only be used for coffee preparation and to heat water. Use for any other purpose will be deemed improper. JURA Elektroapparate AG cannot accept any responsibility for the
consequences of improper use.
Before using the machine, read these instructions
for use thoroughly and completely and comply
with the instructions they contain. A warranty service is not applicable for damage or defects caused
by non-compliance with the instructions for use.
Keep these instructions for use close to the machine
and pass them on to the next user.
Please carefully read and observe the important
safety information set out below.
To avoid danger of potentially fatal electric shock:
Never use a machine which is damaged or has
U
a defective mains cable.
In the event of signs of damage, for example if
U
there is a smell of burning, unplug the machine
immediately from the power supply and contact JURA service.
If the mains cable of this machine is damaged,
U
it must be repaired either directly by JURA or
by an authorised JURA service centre.
Make sure that the D4 and the mains cable are
U
not located close to hot surfaces.
Be careful to ensure that the mains cable is not
U
trapped and does not rub against sharp edges.
6
Important information
Never open and repair the machine yourself.
U
Do not modify the machine in any way that
is not described in these instructions for use.
The machine contains live parts. If opened,
there is a danger of potentially fatal injury.
Repairs may only be carried out by authorised
JURA service centres, using original spare parts
and accessories.
To completely and safely disconnect the
U
machine from the power supply, first switch
off the D4 using the On/Off button Q. Only
then should you remove the mains plug from
the power socket.
There is a risk of scalds or burns on the spouts or
the hot-water nozzle:
Place the machine out of the reach of children.
U
Do not touch any hot parts. Use the handles
U
provided.
Be careful to ensure that the hot-water nozzle
U
is correctly installed and clean. If incorrectly
fitted or if it becomes blocked, the hot-water
nozzle might come off.
A defective machine is not safe and could cause
injury or fire. To avoid damage and any associated
risk of injury or fire:
Never allow the mains cable to loosely hang
U
down. The mains cable could pose a tripping
hazard or become damaged.
Protect the D4 from environmental influences
U
such as rain, frost and direct sunlight.
Do not immerse the D4, mains cable or con-
U
nections in water.
7
Important information
Do not put the D4 or any individual parts in
U
the dishwasher.
Do not use alkaline cleaning agents; only use
U
a soft cloth and mild cleaning agents.
Before cleaning, switch the D4 off with the
U
On/Off button Q. Always wipe the D4 with a
damp cloth rather than a wet one, and protect
it from prolonged exposure to water splash.
Only connect the machine to the mains
U
voltage in accordance with the information on
the rating plate. The rating plate is located on
the underside of your D4. Further technical
data is provided in these instructions for use
(see Chapter 9 ‘Technical data’).
Connect the D4 directly to a domestic power
U
socket. Using multi-socket adapters or extension cords may cause overheating.
Please only use original JURA maintenance
U
products. Use of products that are not explicitly recommended by JURA could damage the
machine.
Do not use any coffee beans treated with
U
additives or caramelised coffee beans.
Only fill the water tank with fresh, cold water.
U
Switch the machine off with the On/Off but-
U
ton Q if you are going to be absent for a longer
period of time and remove the mains plug
from the power socket.
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
Keep children under the age of 8 away from
U
the machine, or supervise them constantly.
8
Important information
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 must be able to recognise and understand the potential dangers arising from incorrect use.
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 in how to
U
use the machine safely
must be supervised by a responsible person when
using it, or must be instructed in how to use it correctly.
Safety when handling the CLARIS Smart filter cartridge:
Filter cartridges should be kept out of the
U
reach of children.
Store filter cartridges in a dry place in the
U
sealed packaging.
Protect cartridges from heat and direct
U
sunlight.
Do not use damaged filter cartridges.
U
Do not open filter cartridges.

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.
