1 Preparing and using for the first time
1 Preparing and using for the first time
Visit us on the Internet. You can download short operating instruc-
tions for your machine from the JURA website (www.jura.com). You
will also find interesting and up-to-date information on your JURA
and on every aspect of coffee.
When setting up your JURA, please note the following:
UPlace the JURA on a horizontal surface that is not sensitive to
water.
UChoose a spot for your JURA which protects the machine
against overheating. Ensure that the ventilation slots are not
covered.
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.
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 briefly (for 1second) under flowing water.
Shake off the water.
TWait for about 1minute.
