2.5 How to adjust a coffee?
After installation, the machine must always be adjusted
for the coffee beans to be used. Use this chapter to
help you do this. Once the coffee-making process has
been set, the user must always use the same bean
melange (mixture).
Coffee crème (lungo)
Always start with adjusting a
Coffee
(usually button
1). First make a couple of coffee without changing the
settings and measure the brewing time of this cup of
coffee.
The coffee brewing process time is from the moment
when the pump starts until the moment the pump
stops.
The brewing time of a coffee is dependent on two
factors:
• grind
• coffee dosage
Adjust the grinder in such away that a good cup of
coffee is made in accordance with the brewing times
shown on the right. Make use of Chapters 2.2 to 2.4
Espresso
Once the coffee Creme has been set, there is not much
more to be set for the Espresso.
Because the same coffee grind is used for an Espresso
based drink, the brew time for an Espresso (50 ml) will
be much shorter than a normal coffee.
If there is still volume left in the brew chamber from the
espresso group (Standard: max. 9,0 g. / XL: max.12,5 g.)
its possible to increase the grinding time.
By increasing the grinder time for the espresso drink
in small steps, more coffee will be dispensed into the
brewer chamber. This created more resistance and a
longer brewing time.
