4.1 Fremstilling af espresso
- Sørg for, at vandtanken er fyldt.

- Add finely ground espresso coffee to the filter. Use the measuring spoon to add 1 scoop for a single espresso or 2 scoops for a double espresso.
- Let tamp the coffee grounds with the flat end of the measuring spoon. Ensure the coffee is level and not overfilled.

4.2 Brug af mælkeskummeren
The integrated milk foam nozzle allows for frothing milk for cappuccinos and latte macchiatos, or dispensing hot water for tea.
- Fyld en kande med kold mælk (med eller uden mælk) til cirka en tredjedel.
- Turn the control dial to the steam position (steam icon). Wait for the indicator light to show the machine is ready for steam.
- Submerge the milk frother nozzle just below the surface of the milk.
- Slowly turn the control dial to the steam release position. Steam will begin to froth the milk.
- Move the pitcher up and down gently to create a consistent foam.
- Once desired foam consistency and temperature are reached, turn the control dial back to the standby position.
- Immediately clean the milk frother nozzle after use (see Maintenance section).
