Safety Precautions
- Always ensure the machine is unplugged before cleaning or when not in use.
- Do not immerse the machine, cord, or plug in water or any other liquid.
- Keep hands and face away from the steam wand during operation to avoid burns.
- Ensure the water reservoir cap is securely tightened before brewing to prevent hot water or steam from escaping.
- Only use medium and coarse ground coffee. Fine ground coffee (less than 0.5mm) can cause blockages and affect performance.
- Never fill the Tritan cup beyond the 4-cup (240 ml) mark.
- Do not remove the filter holder or water reservoir cap during operation.

Setup
- Initial Cleaning: Before first use, wash the portafilter, Tritan carafe, and measuring spoon with warm, soapy water. Wipe the exterior of the machine with a damp cloth.
- Add Water: Unscrew the water reservoir cap on top of the machine. Fill the reservoir with fresh, cold water. Do not exceed the 4-cup (240 ml) maximum fill line. Securely screw the cap back on.
- Add Coffee Grounds: Place the desired amount of medium or coarse ground coffee into the portafilter. Use the tamper end of the measuring spoon to gently press the coffee grounds. Ensure no coffee grounds are on the rim of the filter.
- Attach Portafilter: Align the portafilter with the slot on the machine. Insert it and turn the handle to the left until it aligns with the "LOCK" symbol.
- Place Carafe: Position the Tritan carafe on the drip tray directly under the portafilter.

Ensure water level does not exceed the 4-cup mark in the carafe.

Always use medium ground coffee (greater than 0.5mm) for optimal brewing.

Ensure the edge of the filter is clean of coffee grounds before attaching.

Properly align the portafilter handle with the "LOCK" position for secure brewing.
Operating Instructions
Making Espresso
- Ensure the machine is plugged into a suitable power outlet.
- Turn the control knob to the "Brew" position. The indicator light will illuminate, signifying that the machine is heating up.
- Once the machine is preheated (typically within 2-3 minutes), coffee will begin to dispense into the carafe.
- When the desired amount of coffee is brewed (up to 4 cups), turn the control knob to the "OFF" position to stop brewing.

The 800W heating system ensures fast brewing for your convenience.
Frothing Milk
The integrated steam wand allows you to create silky, dense milk froth for cappuccinos and lattes. For best results, use whole milk.
- After brewing coffee, or if you only wish to froth milk, turn the control knob to the "Steam" position. Allow the machine to preheat until steam is consistently released from the wand.
- Fill a pitcher with cold milk (preferably whole milk).
- Immerse the steam wand into the milk, just below the surface. The steam wand features a 270-degree adjustment for ease of use.
- Turn the control knob to the "Steam" position to release steam. Move the pitcher up and down to create desired froth.
- Once frothed, turn the control knob to "OFF" and carefully remove the pitcher.

For best frothing results, use whole milk.

The powerful steam wand with 270-degree adjustment allows for easy milk frothing.

Maintenance and Cleaning
Regular cleaning ensures the best taste and extends the life of your espresso machine.
- After Each Use:
- Immediately clean the steam wand after frothing milk by wiping it with a damp cloth to prevent milk residue from drying and blocking the nozzle.
- Remove the portafilter, discard used coffee grounds, and rinse the filter and portafilter under running water.
- Empty and rinse the Tritan carafe.
- Empty and clean the drip tray.
- Periodic Cleaning:
- Wipe down the exterior of the machine with a soft, damp cloth. Do not use abrasive cleaners.
- Descaling: Depending on water hardness, descale the machine every 2-3 months. Use a descaling solution specifically designed for coffee machines, following the product's instructions. Run the solution through the machine as if brewing coffee, then rinse thoroughly with plain water.
