Z Never clean with scouring powders or hard implements.
Z Ensure that the ventilation slots are not covered.
Z Never pull out the drip tray during the brewing process. Only
pull the drip tray when the display instructs you or when the
appliance is ready for use.
Z Never fill instant coffee, chocolate mix etc. into the bean

3 Preparing and using for the first time
When setting up your E4, please note the following:
U
Place the E4 on a horizontal surface that is not sensitive to
water.
U
Choose a spot for your E4 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 discoloration of the Aquadur® test strip and the
description on the packaging.

) you can make two additional
specialty coffees: the caffè Barista and the lungo Barista.
Coffee 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.

It is easy to make permanent settings for the amount of water for all
specialty 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 desired specialty coffee must be prepared within
approximately one minute after filling with the ground coffee.
Otherwise the E4 stops the operation and is once more ready
for use.

Daily maintenance of the machine and hygiene when handling
coffee 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 Open the water tank cover.
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 E4. Carry out the
following steps:

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
