Operating Instructions

1. Grinding Coffee Beans

1. Ensure the bean hopper is filled with fresh coffee beans.
2. Adjust the grind setting using the dial on the bean hopper. There are 30 levels, from coarse to fine, to suit different brewing preferences.
3. Insert the portafilter into the grinding cradle. The machine will automatically grind the selected amount of coffee into the portafilter.

2. Brewing Espresso

1. Preheat: Turn on the machine. The preheating time is less than 90 seconds. The coffee indicator light will illuminate when the machine is ready for brewing.
2. Tamp: After grinding, use the tamper to press the coffee grounds firmly and evenly into the portafilter.
3. Insert Portafilter: Securely insert the portafilter into the group head.
4. Place Cups: Place one or two preheated cups on the drip tray under the portafilter spouts. The machine features a cup warmer on top to preheat your cups.

6. Pre-Infusion: The machine will automatically perform a low-pressure pre-infusion before full extraction. This process ensures the coffee powder fully absorbs water, leading to a more even and complete extraction.

1. Fill the milk frothing pitcher with cold milk.
2. Position the steam wand into the milk, just below the surface.
3. Turn the steam control knob to activate the steam wand.
4. Move the pitcher up and down to create microfoam.
5. Once desired texture is achieved, turn off the steam control knob.
6. Wipe the steam wand immediately with a damp cloth to prevent milk residue from drying.
