1. Preheat: Ensure the machine is powered on and has reached the desired brewing temperature (176-215°F). The integrated touch screen displays the temperature.
2. Grind Coffee: Use fresh, finely ground coffee. For a single shot, use 9-12g; for a double shot, use 17-20g.
3. Fill Portafilter: Place the appropriate filter basket into the 58mm portafilter. Fill with ground coffee.
4. Tamp: Use the tamper to press the coffee grounds firmly and evenly. Aim for consistent pressure.
5. Attach Portafilter: Insert the portafilter into the group head and twist firmly to secure it.
6. Place Cup: Position your espresso cup(s) under the portafilter spouts.
7. Extract Espresso:
   • For automatic extraction, press the Automatic Extraction Button (☕☕).
   • For manual control, press the Manual Extraction Button (☕) to start and press again to stop.
   The ideal extraction time is 25±5 seconds for a balanced shot.

5.2 Adjusting Brewing Parameters

The G3007L allows customization of brewing parameters for your preferred taste.

• Brewing Temperature: Adjustable range of 176-215°F (80-102°C). Use the touch screen to set.
• Pre-infusion Time: Adjustable from 0-30 seconds. This allows the coffee grounds to bloom before full pressure extraction.
• Brewing Time: Adjustable from 10-120 seconds for fine-tuning extraction.

Refer to the detailed user guide for specific instructions on accessing and adjusting these settings via the touch screen interface.

5.3 Milk Frothing with Steam Wand

The upgraded three-hole stainless steel steam wand creates silky, delicate milk foam for lattes and cappuccinos.

Figure 5.3: The three-hole steam nozzle allows for efficient milk frothing.

1. Fill a stainless steel frothing pitcher with cold milk (dairy or non-dairy) to just below the spout.
2. Position the steam wand over the drip tray and open the Steam Knob briefly to purge any condensed water. Close the knob.
3. Immerse the tip of the steam wand just below the surface of the milk.
4. Open the Steam Knob fully. You will hear a hissing sound as air is incorporated into the milk.
5. As the milk volume increases and warms, lower the pitcher slightly to keep the tip just below the surface.
6. Once the milk reaches the desired temperature (around 140-150°F or 60-65°C) and texture, close the Steam Knob.
7. Immediately wipe the steam wand with a damp cloth to prevent milk residue from drying.
