HOW TO BREW
- Place a BUNN® coffee filter into the brew funnel.
- Scoop ground coffee into the filter.
- Gently shake the brew funnel to level the grounds.
- Slide the funnel into the funnel rails.
- Fill the carafe with water: 20 oz for 4 cups, 50 oz for 10 cups.
- Open lid and pour water into the coffee maker.
- Position the carafe on the warmer plate (or on the base for Thermal models).
- Close the lid.
- Flip the warmer switch to ON for a glass carafe brewer.
- Wait 4 minutes for the drip-out to complete.
NOTE: Your thermal carafe holds coffee hot for about 2 hours. For best results, preheat the carafe by filling it with hot water, let sit for 30 seconds, then empty before beginning to brew.
BASIC CLEANING
FOR SPEED BREW MODELS (Excluding Thermal models):
- Wash the brew funnel and glass carafe after each use.
- Both are top rack dishwasher safe.
Important: Separate the carafe lid from the carafe when washing in the dishwasher, and use the top shelf only for both the glass and the lid. If washing by hand, use a mild, non-abrasive dish soap. - Wipe the outside of the coffee maker occasionally, including the area above the brew funnel. NOTE: After wipe down, ensure that the warmer switch is in the OFF position.
FOR THERMAL MODELS
Important: Do not place the thermal unit in the dishwasher. Do not use an abrasive device to clean the carafe, because it will scratch the stainless steel. Occasionally, remove the brew-through valve on the Thermal Carafe lid and clean with mild, non-abrasive detergent. To remove the valve, lift at the edge and pull up. Be sure to clean the passage where the valve is located.
- To remove coffee stains from inside the thermal carafe, place a paper filter in the brew funnel and pour 2 teaspoons of powder dishwasher detergent into the brew funnel.
- Pour one carafe of water into the coffee maker.
- Place the carafe under the funnel and close the lid.
- When the brewing cycle stops, remove the brew funnel and discard the filter.
- Rinse the funnel.
- Allow the carafe to sit for about 15 minutes.
- Use a soft bristled brush to clean the inside and outer rim of the carafe.
- Scrub the carafe pour lip and lid with a soft cloth, warm water, and mild detergent.
- When finished, pour out the solution in the carafe.
- Rinse the carafe and the lid.
CLEANING THE SPRAYHEAD
Cleaning the sprayhead tube removes deposits formed by natural mineral content in your water. The more mineral content in your water, the more you should clean. A good rule of thumb is to clean the sprayhead every 3 months. If you have very hard water, then twice a month may be necessary.You will need: a toothpick, dish soap, and a soft cloth.
- Press the tank power switch to the OFF position, unplug the coffee maker and allow it to cool for at least 30 minutes. NOTE: Water in the reservoir may still be hot. Do not tip the machine.
- Remove the funnel and unscrew the sprayhead, loosening with your fingertips.
- Check the sprayhead holes and clear any deposits with the toothpick.
- Clean the sprayhead with a cloth and dish soap. Rinse with water.
- Reinstall the sprayhead.
- Reinsert the brew funnel.
- Plug in the coffee maker. Press the tank power switch to the ON position.
- Wait 15 minutes for the water in the tank to reach brew temperature.
- Your machine is again ready for brewing.
NOTE: Cleaning the sprayhead tube with a deliming tool removes deposits formed by natural mineral content in your water. The more mineral content in your water, the more you should clean. A good rule of thumb is to clean the machine, sprayhead tube and sprayhead every 3 months. If you have very hard water, then twice a month may be necessary if the brew time slows. See the Troubleshooting section if brew time is too slow.
ROUTINE CLEANING

- Repeat the process of cycling fresh cold water 3 or more times, or until you no longer smell vinegar.
- Remove the funnel and reattach the sprayhead.
