5. Operating Instructions

5.1 Making Espresso

For optimal results, use freshly roasted and ground coffee beans.

Figure 6: Parameters for perfect coffee extraction.

1. Pre-heat: Ensure the machine is fully pre-heated (indicator lights solid). Place your espresso cup on the cup warming area.
2. Prepare Portafilter: Insert the desired filter basket (single or double) into the portafilter.
3. Grind Coffee: Grind fresh coffee beans to a fine consistency suitable for espresso.
4. Dose Coffee: Fill the filter basket with the appropriate amount of ground coffee (9-12g for single, 17-20g for double).
5. Tamp: Use a tamper to press the coffee grounds firmly and evenly into the basket. Ensure the surface is level.
6. Attach Portafilter: Wipe any excess coffee from the rim of the portafilter. Insert the portafilter into the group head and twist firmly to lock it into place.
7. Extract Espresso: Place your pre-warmed cup(s) under the portafilter spouts. Press the automatic extraction button for a standard shot, or the manual extraction button to control the volume manually. Monitor the pressure gauge for optimal extraction (typically 9-12 bar).
8. Stop Extraction: If using manual extraction, press the manual extraction button again to stop the flow when the desired volume is reached (approx. 25-30 seconds for a double shot).
9. Remove Portafilter: Carefully remove the portafilter by twisting it counter-clockwise. Dispose of the used coffee puck.

5.2 Steaming Milk

1. Prepare Milk: Fill a stainless steel frothing pitcher with cold milk (dairy or non-dairy) up to just below the spout.
2. Activate Steam: Press the steam button. The indicator light will flash and then become solid when the steam function is ready.
3. Purge Steam Wand: Briefly open the steam knob to release any condensed water from the wand. Close the knob.
4. Froth Milk: Immerse the tip of the steam wand just below the surface of the milk. Open the steam knob. Angle the pitcher to create a whirlpool effect. For foam, keep the tip near the surface; for hot milk, immerse it deeper.
5. Monitor Temperature: Continue steaming until the milk reaches the desired temperature (around 140-150°F or 60-65°C). The pitcher will become hot to the touch.
6. Stop Steaming: Close the steam knob, then remove the pitcher.
7. Clean Steam Wand: Immediately wipe the steam wand with a damp cloth to remove any milk residue. Briefly open the steam knob again to purge any milk from inside the wand.

• Steam Wand: As described in the steaming section, wipe and purge the steam wand immediately after each use.
• Drip Tray: Empty and rinse the drip tray daily or when the indicator floats up.
• Water Tank: Rinse the water tank daily and refill with fresh water.
