4. Operating Instructions

This section details how to brew coffee using your crosson Commercial Airpot Coffee Brewer.

4.1 Brewing Coffee

1. Prepare Airpot: Ensure the thermal airpot carafe is clean and empty. Place it securely on the brewer's base.
2. Add Coffee Grounds: Insert a standard coffee filter into the brew basket/funnel. Add your desired amount of ground coffee. For optimal flavor, use approximately 2 tablespoons of medium-ground coffee per 6 ounces of water.
3. Add Water (Manual Water Inlet): Open the water reservoir lid. Carefully pour cold, fresh water into the reservoir up to the desired fill line. The maximum capacity is 2.2 liters. Close the reservoir lid.
4. Start Brewing: Press the brew button or activate the brewing cycle according to your specific model's controls. The brewer will heat the water to an optimal temperature of 195℉ to 205℉ and dispense it over the coffee grounds.
5. Brewing Complete: The brewing process for a full 2.2L airpot typically takes about 10 minutes. Once the water has stopped flowing into the airpot, the brewing cycle is complete.

1. Position Cup: Place a cup or mug directly under the airpot's spout.
2. Press Lever: Firmly press down on the lever-action pump located on the airpot lid. Coffee will dispense from the spout.
3. Release Lever: Release the lever to stop the flow of coffee.

5. Cleaning and Maintenance

Regular cleaning ensures optimal performance and longevity of your coffee brewer.

5.1 Daily Cleaning

5.2 Descaling (Monthly or as Needed)

Mineral deposits from water can build up over time, affecting brewing performance. Descale your brewer regularly.

1. Prepare Descaling Solution: Mix a descaling solution according to the manufacturer's instructions, or use a solution of white vinegar and water (e.g., 1 part vinegar to 2 parts water).
2. Run Cycle: Pour the descaling solution into the water reservoir. Place the empty thermal airpot carafe under the brew basket. Run a full brew cycle.
3. Soak: After the cycle, let the solution sit in the airpot and brewer's internal components for 15-30 minutes.
4. Rinse Cycles: Discard the descaling solution. Run at least two full brew cycles with fresh, clean water to thoroughly rinse out any remaining solution.
