Task 2: Power Off the Bevi.

1. Power off the Bevi using the power switch on the front of the chiller.
2. Disconnect the power cord from the back of the chiller.

Task 3: Remove the chiller from the cabinet.

1. Carefully lift the front of the chiller so the locating tabs on the bottom can come up and out of the ventilation holes.

2. Slide the chiller forward so the front hangs over the edge of the cabinet.
3. Remove the red locking clip and disconnect the 3/8” water supply line from the back of the chiller.
   • This step may not be necessary if there is enough slack on the water line to fully remove the chiller without putting tension on the tubing.

4. Lifting from the front and the rear grab handle, carefully lift the chiller out of the cabinet and place on the floor.

Task 4: Remove the Top Panel.

1. Using a #2 Phillips screwdriver, loosen the two screws securing the top panel of the chiller.
   • The screws are captive and will remain attached to the panel.
2. With the screws fully loosened, lift up on the front of the panel up and out of the locating tabs at the back to remove it from the chiller.
3. Place the panel to the side.
4. With the panel removed, you now have access to the Ice Bank Valve.

Task 5: Disconnect the Low CO2 Switch.

1. Cut the zip ties securing the Low CO2 switch to cross brace.

2. Disconnect the 1/4” CO2 tubing from the carbonator.
   1. Remove the red locking clip.
   2. Disconnect the 1/4" tube from the push-to-connect fitting on the carbonator CO2 input.

3. Carefully feed the 1/4” CO2 tubing out from under the cross brace.
4. Move the Low CO2 Switch assembly aside to gain better access to the Ice Bank Valve.

Task 6: Removing the Ice Bank Valve.

1. Locate the Ice Bank Valve in the center of the chiller, underneath the cross brace.

2. Prior to disconnecting any water tubing or electrical leads, take a photo of the fully installed Ice Bank valve.
   • NOTE: This is useful to reference when installing the new Ice Bank valve.
3. Disconnect the black and white power wires from the valve.
   • If necessary, pliers can be used to gently grasp and pull the connectors in order to remove them.

4. Disconnect the 1/4” tubing connecting the Ice Bank Valve to the demand pump.
   1. Remove the red locking clips from the push-to-connect fitting.
   2. NOTE: Depending on the manufacturing date of the chiller, red locking clips may or may not be present on any of the internal water connections.
   3. Disconnect the 1/4" tube from the input.

5. Using a #1 Phillips screwdriver, loosen both screws securing the valve to the ice bank’s top.

6. Carefully remove the Ice Bank Valve and fill tube from the chiller.

7. Disconnect the 1/4” tube from the valve. The tube will be reconnected to the new valve.

Task 7: Install the new Ice Bank Valve.

1. Unpackage the new valve.
2. Connect the 1/4” ice bank fill tube to the valve.

3. Place the new Ice Bank Valve into position on the top of the chiller.
   • Ensure the 1/4” tube is seated into the hole on top of the ice bank.

4. Reinstall the 2 Phillips screws to secure the valve to the top of the ice bank.
5. Reconnect the 1/4” input tube to the Ice Bank Valve.
   1. Ensure all tubing connections are fully seated into the push-to-connect fittings.
   2. If present, reinstall the red locking clip.

6. Reconnect the power connectors to the valve.
   1. Ensure the connectors are fully seated.
   2. The Ice Bank Valve does not have any polarity, so the orientation of the wires does not matter.

Task 8: Reconnect the Low CO2 switch.

1. Feed the 1/4” tubing back under the cross brace.
2. Reconnect the tube to the CO2 input on the carbonator.
   • If present, reinstall the red locking clip.
3. Install new zip ties to secure the Low CO2 Switch.

Task 9: Test for Leaks

1. At this time, it is recommended that you test the system for leaks prior to fully reinstalling in the cabinet.
2. If it was disconnected during removal, reconnect the 3/8” water supply tube.
   1. Ensure the tubing is fully seated into the push to connect fitting.
   2. Reinstall the red locking clip.
3. Turn on the water supply.
4. Turn on the CO2 Tank.
5. Reconnect the chiller power cord.
6. Power on the chiller.
7. Once the chiller is powered on, the water system should begin to fill.
   1. Inspect all tubing and fittings to ensure there are no leaks present.
   2. If there are leaks, turn off the water supply and power off the chiller.
   3. Inspect all fittings to ensure tubing connections are fully seated.
8. If no leaks are present, continue to Task 10.

Task 10: Reinstall the Chiller.

   1. Take care not to pinch any wiring in the panel.
   2. Ensure the locating tabs slot into place
   3. Tighten the screws to secure the panel.
2. Carefully lift the chiller into place in the cabinet.
   • Ensure the locating tabs on the bottom of the chiller fit into the ventilation holes and the chiller sits flush on the base of the cabinet.

NOTE: Avoid spilling water from the ice bank by taking extra care to keep the chiller flat and level, and minimize any excess handling.

3. Once reinstalled, power on the chiller.
4. Navigate back to the troubleshooting tools menu.
5. In the front access panel, open the buffer tank valve.

NOTE: Confirm that the Filter Flush valve is in the closed position.

6. Confirm the Ice Bank is full.
   1. After removing and reinstalling the chiller, it is possible the ice bank is no longer full.
   2. In the Chiller Data section, confirm that Chiller “Full” reads YES.
   3. If the chiller is not full, press “Start” in the Chiller Controls menu to fill the ice bank.

7. Once the Ice Bank is filled, test the functionality of the Bevi.
8. Dispense both Cold and Sparkling water to verify they are working properly.
