3. Setup and First Use
3.1 Unpacking and Placement
Carefully remove all packaging materials and place the coffee maker on a flat, stable, heat-resistant surface. Ensure there is adequate clearance around the unit for proper ventilation.
3.2 Initial Cleaning
Before first use, wash the removable parts (carafe, carafe lid, brew basket, single-serve pod holder, and reusable ground coffee filter) in hot, soapy water. Rinse thoroughly and dry. Wipe the exterior of the coffee maker with a damp cloth.
3.3 Priming the Coffee Maker
To prime the unit, fill the removable water reservoir with fresh water up to the MAX fill line. Place the carafe on the warming plate. Run a full carafe brew cycle without coffee grounds. Discard the water. Repeat this process for the single-serve side, running a large cup size brew cycle without a K-Cup pod or ground coffee. This cleans the internal components and prepares the machine for brewing.

5. Care and Maintenance
5.1 Daily Cleaning
After each use, unplug the coffee maker and allow it to cool. Remove and wash the carafe, carafe lid, brew basket, single-serve pod holder, and reusable ground coffee filter in warm, soapy water.

5.2 Descaling (Mineral Deposit Removal)

- Turn the coffee maker back on to complete the brew cycle.
- Discard the vinegar solution.
- Fill the water reservoir with fresh, cold water and run 2-3 full carafe brew cycles with only water to rinse thoroughly.
- Repeat steps 1-7 for the single-serve side, using a large cup size setting.
