The
S
team
A
ir
option allows, particularly when making cappuccino, to foam the milk very easily and
automatically: the supply of air mixed with steam brings milk to a programmed temperature 60° to 70° (140°F
to 158°F) and foams it.
The stop is done automatically when the temperature is reached which saves milk from boiling. By this way
the milk qualities are preserved.
Once the air/steam adjustment is defined, the operation is as follows:
- Insert the
S
team
A
ir outlet into the milk container
- Push on the
S

A
ir key
Wait for it to stop automatically.
The
