Setup and Installation
The Bunn Axiom-DV-TC brewer requires a continuous water inlet connection and proper electrical wiring for operation.
Water Connection

Electrical Connection
- This unit is dual voltage adaptable and can operate at 120V/15 amp or 120/208-240V/20 amp. Consult a qualified electrician for proper wiring and installation.
- Ensure the electrical circuit is capable of handling the rated load of the brewer.
Initial Fill and Heating
- After securely connecting water and power, turn the main power switch on the back of the unit to the "ON" position.
- The brewer will automatically begin to fill its internal tank and heat the water to the optimal brewing temperature (approximately 200°F). This initial heating process may take several minutes.

Settings and Features
Energy-Saver Mode
The energy-saver mode is designed to reduce the internal tank temperature during periods of inactivity, thereby conserving energy.
- To activate or deactivate this mode, refer to the specific instructions provided in the comprehensive manual or on the control panel.
- When in energy-saver mode, it will take approximately 10-18 minutes for the brewer to return to the optimal brewing temperature.
Programmable Settings
The brewer allows for customization of various settings directly from the front panel, including brew level, cold brew lock-out, and tank temperature. Consult the full product manual for detailed programming steps and options.
Maintenance
Daily Cleaning
- After each use, remove and thoroughly clean the brew funnel and thermal carafe with mild soap and water.
- Wipe down the exterior surfaces of the brewer with a damp cloth. Do not use abrasive cleaners or scouring pads, as these can damage the finish.
Descaling
Regular descaling is crucial to maintain optimal performance and coffee quality, particularly in areas with hard water.
- Follow Bunn's recommended descaling procedures, which typically involve using a descaling solution and performing several flushing cycles.
- Refer to the comprehensive manual for detailed descaling instructions specific to your model.
Filter Replacement
Ensure a fresh coffee filter is used for each brew cycle to achieve the best coffee flavor and prevent clogs.
Troubleshooting
No Power
- Check the main ON/OFF switch located on the back of the unit.
- Verify that the power cord is securely plugged into a functional electrical outlet.
- Inspect the circuit breaker or fuse for the outlet to ensure it has not tripped.
No Water Flow
- Ensure the water supply valve connected to the brewer is fully open.
- Check the water line for any kinks or obstructions.
- Verify that the water pressure is adequate for the brewer's operation.
Coffee Not Brewing
- Ensure the brewer's display indicates "READY TO BREW," meaning it has reached the optimal temperature.
- Verify that the brew funnel is correctly and fully inserted into its position.
- Press the "BREW" button firmly to initiate the brewing cycle.
No Automatic Start-Up
This commercial unit does not feature an automatic start-up timer. It must be manually turned on or left in an "ON" state (with or without energy-saver mode activated) to maintain temperature and be ready for brewing.
