ible accessory (e.g. the Cool Control milk cooler). To do this, the
receiver of the Cool Control or the JURA Smart Connect must be
plugged into the service socket.
EThe Smart Connect can be protected against unauthorised
access using a PIN. Activate the PIN function via J.O.E.®– your
JURA app. You will find more information at
www.jura.com/smartconnect.
EPlease note that you can only connect either the accessory or
J.O.E.®to the coffee machine via Smart Connect and not both
at the same time.

buttons.
UYou can stop preparation at any time. To do this, press the
‘Cancel’ button.
Coffee tastes best served hot. A cold porcelain cup cools the bever-
age – and impairs the taste. We therefore recommend prewarming
the cups. The full coffee aroma can develop only in prewarmed cups.
You can purchase a JURA cup warmer from your specialised dealer.
You can make permanent settings for all products in programming
mode (see Chapter 4 ‘Permanent settings in programming mode –
Adjusting the product settings’).
Your WE8 prepares latte macchiato, cappuccino and other speciality
coffees with milk at the touch of a button. There is no need to move
the glass or cup.
EThis chapter applies to the professional fine foam frother and
the fine foam frother.
Example:Proceed as follows to prepare one latte macchiato.
Precondition:The start screen is displayed. Milk is connected to the
fine foam frother.
TPlace a glass under the fine foam frother.
TPress the ‘Latte macchiato’ button.
‘Latte macchiato’, the preset amount of milk foam flows into
the glass.

EThere is a short interval while the hot milk separates from the
milk foam. This allows the typical layers of a latte macchiato
to form. You can choose the length of this interval in program-
ming mode (see Chapter 4 ‘Permanent settings in program-
ming mode – Adjusting the product settings’).
Coffee preparation starts. The preset amount of water for
espresso flows into the glass. Preparation stops automati-
cally. Your WE8 is once more ready for use.
To ensure that the fine foam frother always works properly, you
must clean it daily when you have been preparing milk (see Chap-
ter 5 ‘Maintenance – Cleaning the fine foam frother’).
Example:Proceed as follows to prepare one coffee.
Precondition:The start screen is displayed.
TPlace a cup under the coffee spout.
TPress the ‘Coffee’ button.
Preparation starts. ‘Coffee’ and the coffee strength are dis-
played. The preset amount of water for coffee flows into the
cup.
Preparation stops automatically. Your WE8 is once more
ready for use.
To prepare two speciality coffees, press the appropriate preparation
button twice (within approximately 1 second).
Example:Proceed as follows to prepare two espressi.

To ensure that the fine foam frother always works properly, you
must clean it daily when you have been preparing milk (see Chap-
ter 5 ‘Maintenance – Cleaning the fine foam frother’).
You can choose to use a second coffee variety, for example decaf-
feinated coffee, with the filter funnel for ground coffee.
Basic information about ground coffee:
UNever add more than two level measuring spoons of ground
coffee.
UUse ground coffee which is not ground too finely. Very fine
coffee can block up the system so that the coffee only comes
out in drips.
UIf you did not fill the machine with a sufficient amount of
ground coffee, ‘Not enough ground coffee’ is displayed and
the WE8 stops the operation.
UThe desired speciality coffee must be prepared within approx-
imately one minute after filling with the ground coffee. Oth-
erwise the WE8 stops the operation and is once more ready
for use.
UAll speciality coffees with ground coffee are always prepared
following the same model.
Example:Proceed as follows to prepare one espresso using ground
coffee.
