WARNING: HOT WATER / HOT LIQUID. Exercise extreme caution when operating the hot water dispenser and during the brewing process. Surfaces may become hot during operation.
- Always disconnect power before cleaning or servicing the brewer.
- Do not immerse the brewer in water or other liquids.
- Ensure the electrical supply matches the voltage requirements of the brewer (120V or 240V).
- Keep hands and face clear of the brew funnel and airpot during brewing to avoid contact with hot liquids or steam.

3. Setup and Installation
- Unpacking: Carefully remove the brewer from its packaging. Inspect for any shipping damage. Remove all protective films and packing materials.
- Placement: Place the brewer on a stable, level, and heat-resistant surface. Ensure adequate clearance around the unit for ventilation and access. The approximate dimensions are 28.4 inches (H) x 26 inches (L) x 12 inches (W).
- Water Connection: This brewer requires a plumbed-in water supply. Connect the brewer to a potable cold water line using appropriate plumbing fittings. Ensure all connections are secure and leak-free. A water filter is recommended for optimal performance and longevity.
- Electrical Connection: The Axiom DV-APS is a dual-voltage unit. Verify the brewer is configured for your local electrical supply (120V or 240V). Connect the brewer to a dedicated, grounded electrical circuit. Consult a qualified electrician if unsure.

5. Maintenance and Cleaning
Regular cleaning and maintenance are crucial for the performance and longevity of your brewer.
- Daily Cleaning: Wipe down the exterior surfaces with a damp cloth and mild detergent. Clean the drip tray and airpot thoroughly.
- Brew Funnel and Filter: After each use, remove the reusable filter and wash it along with the brew funnel using warm, soapy water. Rinse thoroughly.
- Spray Head: Periodically check the spray head for mineral deposits. If clogged, gently clean the holes with a small brush or pin.
- Descaling: Depending on water hardness, the brewer will require periodic descaling to remove mineral buildup. Follow Bunn's recommended descaling procedure, typically involving a commercial descaling solution. Refer to the full service manual for detailed descaling instructions.
- Airpot Care: Clean airpots regularly to prevent coffee residue buildup, which can affect taste.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Brewer does not power on. | No power supply; circuit breaker tripped. | Check power cord connection; reset circuit breaker. |
| No water flow during brew. | Water supply off; clogged water line; pump issue. | Ensure water supply is on; check for kinks in water line; contact service if pump suspected. |
| Coffee tastes weak. | Insufficient coffee grounds; incorrect grind size. | Increase coffee amount; use a finer grind. |
| Brewer is leaking. | Loose connections; damaged seals. | Check all water connections; inspect seals for damage and replace if necessary. Contact service for internal leaks. |
