1 Adjust the espresso grinder according to this manual.
2 Enter the menu “Products & Keys”.
3 Select the product selection button “double espresso” to be set.
4 Adjust the product as follows:
• Define the bean hopper (front/rear)

5 Exit the menu with the back arrows.
6 Dispense a double espresso (don’t stop).
