Remove and Replace Procedure

Task 1: Depressurize the water system.

1. Turn off the water source to the Compact Chiller.
2. Open the front access panel on the chiller.
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.

4. Once fully drained, close both the Buffer Tank and Filter Flush valves, and replace the Filter Flush tube into the clips.

5. Navigate to the Troubleshooting Tools screen.
   1. Touch the service icon in the upper left corner.
   2. Touch "Start Service"
   3. Enter the PIN to access the service panel.

6. On the left side of the screen, touch "Machine Alerts".
   • Touch "Troubleshooting Tools"

7. Place a container under the nozzle, and pour COLD water until water is no longer dispensing.

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.

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

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 in tube 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 right side panel.

1. Using a #2 Phillips screwdriver, loosen the two screws at the top of the panel.
2. With the screws fully loosened, slide the panel up and out to release the locating tabs at the bottom.
3. Place the panels to the side.

Task 5: 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 Inlet Solenoid.

Task 6: Remove the Demand Pump Pressure Sensor.

1. Locate the pressure sensor on the top left side of the compact chiller.

2. Disconnect the pressure sensor cable.
   1. Carefully work the pressure sensor out of the side of the chiller to access the cable connection.
   2. Depress the lock latch to release the connector, and disconnect the cable from the sensor.

3. Disconnect the 1/4" tube from the Ambient Out fitting.
   1. Remove the red locking clip.
   2. Disconnect the tube from the push-to-connect fitting.

4. Remove the sensor and 1/4" tube from the left side of the compact chiller.

Task 7: Install the new Pressure Sensor.

1. Unbox the new Demand Pump Pressure sensor.
2. Feed the 1/4" tubing and pressure sensor into the chiller from the left side.

3. Reconnect the 1/4" tube to the Ambient Out fitting.
   1. Ensure the tubing is fully seated into the push-to-connect fitting up to the insertion line.
   2. If present, reinstall the red locking clip.

4. Reconnect the pressure sensor cable to the sensor.
   • Ensure the connector fully seats in and clicks into place.

5. Tuck the pressure sensor back into its location on top of the Ice Bank.

Task 8: 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. Reconnect the chiller power cord.
5. In the front access panel, open the buffer tank valve.

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

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 buffer tank, 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 9.

Task 9: Reinstall the Chiller.

1. Reinstall the left side and top panels.
   1. Ensure the locating tabs slot into place.
   2. Tighten the screws to secure the panels.
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.

Task 10: 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, confirm the buffer tank valve is in the open position.

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

3. Confirm the water source is turned on.
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.
   1. Monitor the Dispense Pressure data to confirm the pressure decreases and increases as water is dispensed from the Bevi.
   2. If the pressure data is not reporting correctly, recheck that the sensor cable is properly seated into the sensor.

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.
