- Place the empty glass carafe with its lid on the heating plate.
- Plug the power cord into a suitable wall outlet (220-240V, 50/60Hz).

Operating Instructions
Follow these steps to brew coffee:
- Fill Water Reservoir: Open the lid of the water reservoir and fill it with the desired amount of fresh, cold water. Use the water level indicator on the side of the coffee maker as a guide (up to 15 cups). Do not exceed the maximum fill line.
- Add Coffee Grounds: Place the non-disposable filter holder into its designated position. Add the desired amount of ground coffee into the filter. A general guideline is one tablespoon of ground coffee per cup, but adjust to your taste.
- Position Carafe: Place the glass carafe with its lid securely on the heating plate. Ensure the carafe is correctly positioned to activate the drip-stop mechanism.
- Start Brewing: Plug the power cord into a suitable wall outlet. Press the On/Off switch. The indicator light will illuminate, indicating that the brewing process has started.
- Serving: Once the brewing cycle is complete, the coffee maker will automatically switch to a keep-warm function. The heating plate will keep the coffee warm for approximately 40 minutes before automatically shutting off.
- Turn Off: After serving, or if you are finished with the coffee, press the On/Off switch to turn off the appliance and unplug it from the wall outlet.

Maintenance and Cleaning
Regular cleaning ensures optimal performance and extends the lifespan of your coffee maker.
- Daily Cleaning:
- Always unplug the coffee maker and allow it to cool completely before cleaning.
- Remove the glass carafe, its lid, and the non-disposable filter holder. Wash these parts in warm, soapy water. Rinse thoroughly and dry. These parts are generally not dishwasher safe unless specified otherwise.
- Wipe the exterior of the coffee maker with a soft, damp cloth. Do not use abrasive cleaners or scouring pads.
- Never immerse the main unit, power cord, or plug in water or any other liquid.
- Descaling: Mineral deposits from water can build up over time and affect performance. Descale your coffee maker regularly (e.g., every 2-4 weeks, depending on water hardness).
- Prepare a descaling solution by mixing white vinegar and water (e.g., 1 part vinegar to 2 parts water) or use a commercial descaling agent according to its instructions.
- Pour the solution into the water reservoir.
- Place the empty filter holder and carafe in position.
- Run a brewing cycle. Turn off the appliance halfway through the cycle and let it soak for about 15-20 minutes.
- Resume the brewing cycle until complete.
- Discard the solution and run 2-3 cycles with fresh, clean water to rinse thoroughly and remove any vinegar taste.
