Safety Precautions
- Always ensure the machine is placed on a stable, level, heat-resistant surface.
- Do not immerse the machine, cord, or plug in water or other liquids.
- Keep out of reach of children.
- Unplug the machine when not in use and before cleaning.
- Exercise caution when handling hot surfaces and steam.
- Use only cold, fresh water in the water reservoir.
- Important: Do not use finely ground espresso or any fine ground coffee. Using fine grounds can cause blockages and damage the machine.

Setup
1. Unboxing and Initial Cleaning
- Carefully remove all packaging materials.
- Wash the carafe, filter basket, and removable drip tray in warm, soapy water. Rinse thoroughly and dry.
- Wipe the exterior of the machine with a damp cloth.
2. First Use (Priming the Machine)
- Fill the water reservoir with cold, fresh water up to the "4-cup" mark.
- Place the carafe on the drip tray.
- Ensure the filter basket is empty and the portafilter is securely locked into place.
- Turn the function knob to the "Brew" position.
- Allow the machine to run a full cycle of water through without coffee. This cleans the internal components and primes the pump.
- Discard the water from the carafe.
Operating Instructions
1. Brewing Espresso
- Fill Water Reservoir: Ensure the water reservoir is filled with cold, fresh water to your desired level (1-4 cups).
- Add Coffee Grounds: Place the filter basket into the portafilter. Add the appropriate amount of medium-coarse ground coffee. Do not overfill or tamp too firmly.
- Attach Portafilter: Securely attach the portafilter to the machine by aligning it and twisting it to the "LOCK" position.
- Position Carafe: Place the glass carafe on the drip tray directly beneath the portafilter.
- Start Brewing: Turn the function knob to the "Brew" position. The machine will begin to heat water and extract espresso.
- Monitor Brewing: Brewing 2-3 minutes will yield approximately 4 shots of espresso.
- Stop Brewing: Once the desired amount of espresso is brewed, turn the function knob to the "OFF" position.

2. Frothing Milk
- Prepare Milk: Fill a stainless steel frothing pitcher with cold milk (dairy or non-dairy) to about one-third full.
- Position Steam Wand: Submerge the tip of the steam wand just below the surface of the milk.
- Activate Steam: Turn the function knob to the "Steam" position. Allow a few seconds for steam to build.
- Froth Milk: Move the pitcher slowly up and down, keeping the steam wand tip near the surface to create foam, then deeper to heat the milk.
- Stop Steaming: Once desired foam and temperature are reached, turn the function knob to the "OFF" position.
- Clean Wand: Immediately wipe the steam wand with a damp cloth to prevent milk residue from drying.

3. Making Latte or Cappuccino
Once you have brewed your espresso and frothed your milk, combine them to create your desired beverage:
- Latte: Pour the frothed milk into the espresso, holding back the foam with a spoon, then spoon a thin layer of foam on top.
- Cappuccino: Pour the frothed milk into the espresso, allowing a generous amount of foam to top the drink.

Maintenance
1. Daily Cleaning
- Portafilter and Filter Basket: After each use, remove spent coffee grounds and rinse the portafilter and filter basket under warm water.
- Carafe: Wash the carafe with warm, soapy water after each use.
- Drip Tray: Empty and clean the drip tray regularly to prevent overflow.
- Exterior: Wipe the exterior of the machine with a soft, damp cloth. Do not use abrasive cleaners.
2. Descaling
Mineral deposits can build up over time, affecting machine performance. Descale your machine every 2-3 months, or more frequently if you have hard water.
- Prepare a descaling solution according to the descaler product instructions (or use a mixture of white vinegar and water).
- Fill the water reservoir with the descaling solution.
- Place the carafe on the drip tray.
- Run the machine through a full brew cycle without coffee.
- Repeat the process with clean water to rinse thoroughly.
