Your S8 creates fine, creamy, feather-light milk foam with a perfect
consistency. The most important requirement for frothing milk is
a milk temperature of 39–46 °F (4–8 °C). We would therefore
recommend using a milk cooler or a milk container.
TRemove the protective cover from the milk system.
TConnect the milk pipe to the milk system.
TConnect the other end of the milk pipe to a milk container
or a milk cooler.

Hot coffee, hot steam and hot water can cause scalding. Scalding is
a serious burn.
T Use extreme care when handling hot liquid or steam.
T Allow liquid to cool down before drinking.
T In the event of scalding, rinse affected area with cold water
and seek medical attention.
T Keep children AWAY.
Basic information about preparing drinks:
UDuring the grinding operation you can change the coffee
strength of single products. To do this, move your finger
across the display.
UDuring preparation you can change the preset amounts (e.g.
amount of water or milk foam). To do this, move your finger
across the display.
UYou can stop preparation at any time. To do this, touch
‘Cancel’.
EThe water volume is given as standard in ‘oz’. You can change
this setting to ‘ml’ in programming mode (see Chapter 4
‘Permanent settings in programming mode – Unit for amount
of water’).
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 specialized dealer.
You can make permanent settings for all products in programming
mode (see Chapter 4 ‘Permanent settings in programming mode –
Adjusting the product settings’).
