BUNN CSB2B Speed Brew Elite 10-Cup Coffee Maker Instruction Manual

Introduction

The BUNN CSB2B Speed Brew Elite 10-Cup Coffee Maker is engineered for rapid brewing, producing 10 cups of coffee in approximately 4 minutes. It features an internal commercial-grade stainless steel hot water tank that keeps 70 oz of water at an optimal brewing temperature, allowing for on-demand coffee. The taller funnel accommodates BUNN filters, preventing overflow of coffee grounds. This model delivers a consistently ideal brewed pot of coffee, avoiding burnt flavors often associated with excessive temperatures. It is designed, engineered, and manufactured with commercial practices, ensuring durability and quality.

1. Setup

Before initial use, ensure all removable parts are thoroughly cleaned with warm, soapy water. Rinse completely. Place the coffee maker on a flat, stable surface. The unit is designed to keep water hot continuously, so it should remain plugged in and the internal water heater switch (located on the side/back) should be in the 'ON' position for optimal performance.

Initial Fill: Open the lid on top of the brewer. Pour at least 4 cups of cold water into the brewer. Close the lid. The water will flow into the hot water tank. Wait approximately 15 minutes for the water to heat to the optimal brewing temperature. The blue indicator light on the front will illuminate when the warmer plate is active.

2. Operating Instructions

The BUNN Speed Brew is designed for quick and efficient coffee brewing. Once the initial setup is complete and the water tank is hot, follow these steps for each brew cycle:

1. Prepare Filter Basket: Place a BUNN filter (1/4 inch taller than standard filters) into the brew funnel. Add your desired amount of coffee grounds to the filter.
2. Place Carafe: Ensure the empty carafe is placed securely on the warmer plate beneath the brew funnel.
3. Add Water: Open the lid on top of the brewer. Pour cold, fresh water into the brewer's reservoir. The amount of water added will displace the hot water in the tank, initiating the brew cycle. The pour-in bowl features a water level indicator to guide you.
4. Close Lid: Close the lid firmly. Brewing will begin almost immediately.
5. Enjoy: A full 10-cup carafe of coffee will brew in about 4 minutes. The switch-activated warmer plate will keep your coffee at an optimal serving temperature.

3. Maintenance

Regular cleaning and maintenance will ensure the longevity and optimal performance of your BUNN coffee maker.

• Daily Cleaning: After each use, discard used coffee grounds and filter. Rinse the brew funnel and carafe with warm water. The carafe and brew funnel are dishwasher safe.
• Exterior Cleaning: Wipe down the exterior of the coffee maker with a damp cloth. Avoid abrasive cleaners.
• Descaling: Periodically descale the internal hot water tank to remove mineral buildup. Refer to the detailed user manual for specific descaling instructions and recommended descaling solutions.

4. Troubleshooting

If you encounter issues with your coffee maker, try the following common troubleshooting steps:

• Coffee Not Brewing: Ensure the coffee maker is plugged in and the internal water heater switch (on the side/back) is in the 'ON' position. Verify that water has been added to the reservoir.
• Weak Coffee: Check that you are using the correct amount of coffee grounds for the desired strength. Ensure you are using BUNN filters, which are designed to prevent overflow and allow proper water flow.
• Water Overflowing from Brew Funnel: This often indicates that the coffee grounds are too fine or the filter is not properly seated. Ensure you are using BUNN filters and avoid overfilling the brew funnel with grounds.
• No Hot Water: Confirm the internal water heater switch is 'ON' and the unit has been plugged in for at least 15 minutes to allow the water to heat up.
