4. Setup and First Use

1. Unpack: Carefully remove all packaging materials and ensure all parts are present.
2. Clean: Wash the thermal carafe, its lid, and the removable filter holder in warm, soapy water. Rinse thoroughly and dry. Wipe the exterior of the coffee maker with a damp cloth.
3. First Brew Cycle (Cleaning):
   • Fill the water reservoir with cold water up to the maximum fill line.
   • Place the empty thermal carafe with its lid on the heating plate.
   • Do not add coffee grounds for this cycle.
   • Plug the coffee maker into a grounded electrical outlet.
   • Press the power switch to start the brewing cycle.
   • Allow the full cycle to complete. Discard the hot water.
   • Repeat this cleaning cycle once more with fresh water.
4. Your coffee maker is now ready for use.

5. Operating Instructions

Follow these steps to brew coffee:

1. Fill Water Reservoir: Open the lid of the water reservoir and fill it with fresh, cold water to your desired level, indicated by the water level markings. Do not exceed the maximum fill line.
2. Insert Filter: Place a Melitta #1x2 or #1x4 cone-shaped paper filter (depending on model variant, check your filter holder size) into the removable filter holder.
3. Add Coffee Grounds: Add your desired amount of ground coffee into the paper filter. A general guideline is one tablespoon of coffee per cup (5 oz). Adjust to taste.
4. Position Carafe: Ensure the thermal carafe, with its lid securely attached, is placed correctly on the heating plate beneath the filter holder. The lid must be properly aligned to activate the drip stop mechanism.
5. Start Brewing: Plug the coffee maker into a grounded electrical outlet. Press the power switch. The indicator light will illuminate, and brewing will begin.
6. Automatic Shut-off: The coffee maker will automatically shut off approximately 10 minutes after the brewing cycle is complete. The indicator light will turn off.
7. Serve: Once brewing is complete, carefully remove the thermal carafe to serve. The thermal carafe is designed to keep coffee warm for an extended period without a heating plate.

6. Cleaning and Maintenance

Regular cleaning ensures optimal performance and extends the life of your coffee maker.

Daily Cleaning:

• Always unplug the coffee maker before cleaning.
• Discard used coffee grounds and paper filter.
• Wash the thermal carafe, its lid, and the removable filter holder in warm, soapy water. Rinse thoroughly and dry. These parts are generally not dishwasher safe; refer to specific markings if present.
• 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 of the coffee maker in water or any other liquid.

Descaling (Monthly or as needed):

Mineral deposits from water can build up and affect performance. Descale your coffee maker regularly.

1. Prepare a descaling solution according to the descaler manufacturer's instructions, or use a solution of white vinegar and water (e.g., 1 part vinegar to 2 parts water).
2. Pour the descaling solution into the water reservoir.
3. Place the empty thermal carafe with its lid on the heating plate.
4. Start a brewing cycle. Allow half of the solution to brew through, then turn off the coffee maker and let it stand for 15-20 minutes to allow the solution to work.
5. Turn the coffee maker back on and allow the remaining solution to brew through.
6. Discard the solution and rinse the carafe.
7. Run two full cycles with fresh, cold water to rinse out any remaining descaling solution.
