Operating Instructions
Brewing Coffee
- Fill Water Reservoir: Open the top lid and fill the water reservoir with fresh, cold water using the carafe. Refer to the water level indicator on the side for desired cups (up to 12 cups).

- Auto Shutoff: The coffee maker will automatically shut off after 2 hours for safety and energy saving.

Maintenance and Cleaning
Regular cleaning ensures optimal performance and extends the life of your coffee maker.
- Daily Cleaning:
- Always unplug the coffee maker before cleaning and allow it to cool completely.
- Remove the filter basket and discard used coffee grounds. Wash the filter basket and glass carafe in warm, soapy water. Rinse thoroughly and dry. These parts are also top-rack dishwasher safe.

- Place the empty carafe on the warming plate.
- Press the "ON/OFF" button to start a brewing cycle.
- After about 10 minutes, turn off the coffee maker and let it soak for at least 30 minutes to allow the solution to clean the internal components.
