3. Drain the Buffer Tank.
   1. Ensure the Buffer Tank valve is in the open position.
   2. Remove the Filter Flush tube from the clips and direct it into a bucket,
   3. Open the Filter Flush Valve and drain the Buffer Tank until it is completely empty.

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.

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. Remove the red locking clip and disconnect the 3/8" water in tube from the back of the chiller.
   1. NOTE: 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 right side panel.

1. Using a #2 Phillips screwdriver, loosen the two screws securing the right side panel of the chiller.
2. With the screws fully loosened, lift the panel up and out of the locating tabs at the bottom.
3. Place the panel to the side.
4. With the panel removed, you now have access to the Buffer Tank.

Task 5: Remove the Buffer Tank

1. Remove the red locking clip from the push to connect fitting at the bottom of the buffer tank.
2. With the buffer tank still zip tied to the sheet metal bracket, disconnect the ¼” stem elbow from the push to connect fitting at the bottom of the buffer tank.

3. Using flush cut pliers, cut the zip tie securing the buffer tank to the bracket.
4. Remove the buffer tank from the chiller.
5. Remove the old cut zip tie from the buffer tank bracket.

Task 6: Install the new Buffer Tank

1. Feed the supplied large zip tie through the slots in the metal mounting bracket behind the buffer tank.

2. Insert the buffer tank back into its housing and secure the zip tie around the buffer tank.
   1. If necessary, use a pair of pliers to firmly grasp the zip tie and tighten as much as possible.
   2. Cut any extra length of the zip tie with a cutting tool such that the tail of the zip tie does not obstruct the compact chiller's side panel.

 NOTE: Ensure the head of the zip tie is out of the way of the compact chiller side panel before fully tightening it.

3. Reconnect the stem elbow to the push to connect fitting at the bottom of the buffer tank.
   1. Ensure the stem is fully pushed into the fitting.
   2. Reinstall the red locking clip.

Task 7: Reinstall the Chiller.

1. Reinstall the right side panel.
   1. Take care not to pinch any wiring in the panels.
   2. Ensure the locating tabs slot into place
   3. Tighten the screws to secure the panel.
2. Reconnect the chiller power cord.
3. Carefully lift the chiller into place in the cabinet.
   1. 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.

4. 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.
5. Power on the chiller.

Task 8: Fill the Buffer Tank and Ice Bank.

1. Once the chiller is reinstalled, navigate back to the troubleshooting tools menu.
2. In the front access panel, open the buffer tank valve.

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

3. Turn on the water source.
4. From the "Water" controls menu, open the inlet solenoid.
   1. This will allow water to enter the chiller and fill the buffer tank.
   2. While filling the buffer tank, observe the internal water pressure increasing in the Data section.
   3. Once water pressure has stabilized, the buffer tank should be full.

5. 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.

6. Once the Buffer Tank and Ice Bank are filled, test the functionality of the Bevi.
7. Dispense both Cold and Sparkling water to verify they are working properly.
8. Press "Back" at the top right corner of the screen to exit the Troubleshooting Tools menu.
9. Be sure to resolve any machine alerts that may have fired while servicing the machine.
