der to reach the correct coffee amount adjustment
in the cup.
3 Put the filter-holder (with ground coffee) on the left
unit and the cup under the spout.

small cup).

each dose, remembering to use the filter-holder with
relevant filter and freshly ground coffee.
Then carry out point 6 and repeat point 7 to check
all changed doses.
