4. Setup
4.1 Unpacking and Placement
- Carefully remove the brewer from its packaging.
- Place the brewer on a stable, level surface capable of supporting its weight when full. Ensure adequate clearance for ventilation around the unit.
- Inspect the unit for any shipping damage. Contact your supplier immediately if damage is found.
4.2 Electrical Connection
The Axiom-DV-3 is a dual voltage unit. It can operate at 120V/15 amp or 120/208-240V/20 amp. Ensure the electrical supply matches the brewer's configuration and local electrical codes. Connection should be performed by a qualified electrician.
4.3 Water Connection
This brewer requires a plumbed-in water supply. Connect the brewer to a cold water line with a shut-off valve. A water filter is recommended to prevent mineral buildup and ensure optimal coffee taste. Follow local plumbing codes for installation.
4.4 Initial Cleaning and Priming
- Before first use, clean the exterior with a damp cloth.
- Ensure the water supply is connected and turned on.
- Turn the main power switch (located at the rear) to the 'ON' position. The tank will begin to fill and heat water. This process may take several minutes.
- Once the display indicates 'READY TO BREW', run several cycles of hot water through the brew funnel without coffee to flush the system.
5. Operating Instructions
Note: Coffee decanters are not included and must be purchased separately.
5.1 Brewing Coffee
- Ensure the brewer is powered on and the display shows 'READY TO BREW'.
- Place a clean, empty coffee decanter on the lower warming plate.
- Insert a filter into the brew funnel.
- Add the desired amount of ground coffee to the filter.
- Slide the brew funnel into its position under the spray head.
- Press the 'BREW' button on the control panel to start the brewing cycle.
- Once brewing is complete, carefully remove the brew funnel and discard the used grounds and filter.
- Place the freshly brewed coffee decanter on an upper warmer if desired, or serve immediately.
5.2 Using the Hot Water Faucet
- Ensure the brewer is powered on and water is heated.
- Place a cup or container under the hot water faucet.
- Pull the faucet handle forward to dispense hot water.
- Push the handle back to stop the flow.
- Caution: Hot water can cause burns. Exercise care when dispensing.
5.3 Programming Settings
The Axiom-DV-3 allows for customization of brewing parameters:
- Brew Level: Adjust the volume of coffee brewed per cycle.
- Cold Brew Lock-Out: Prevents brewing if the water temperature is below optimal.
