3 Preparing and using for the first time
When setting up your ENA, please note the following:
UChoose a spot for your ENA which protects the machine
against overheating. Ensure that the ventilation slots are not
covered.
UPlace the ENA on a horizontal surface that is not sensitive to
water.
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 1minute.
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.
