Remove and Replace Procedure

Before Starting

• If the water supply is long enough, you do not need to depressurize the water system.
• If you can verify the water supply tubing has enough slack to remove the chiller without disconnecting, you can start at Task 2.

Task 1: Depressurize the water system.

1. Turn off the water source to the Compact Chiller.
2. Open the front access panel.
3. Turn off the Buffer tank.
   • Rotate the shut off valve to the CLOSED position.

4. Turn off the CO2 tank.
5. Navigate to the Troubleshooting Tools screen.

   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 and Sparkling water until water is no longer dispensing for either selection.

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.
   • CAUTION: Take extra care to move the Chiller as carefully as possible. Keep the chiller flat and level as you move it to avoid any spillage from the Ice Bank.

Task 4: Remove the left side panel.

1. Using a #2 Phillips screwdriver, loosen the two screws securing the top panel of the chiller.
2. With the screws fully loosened, slide the the panel up to release the locating tabs at the base.

3. Place the panel to the side.

Task 6: Remove the 24 V Power Supply.

1. Remove the 24 V Power Supply from the PCB housing.

2. Once the power supply is removed from the PCB housing, take a photo of the wiring connections to reference during reinstallation.
3. Disconnect the white 120VAC connector from the power supply.
   • There is a lock latch on the connector that needs to be depressed to disconnect the cable.

4. Using a #1 Phillips screwdriver, remove the screw securing the yellow/green ground wire to the power supply.

5. Using a #2 Phillips screwdriver, or a flat blade screwdriver, remove the screws securing the yellow and black 24 VDC wires to the power supply.
6. Once all cables are disconnected, remove the power supply from the chiller.

Task 7: Install the new 24 V Power Supply

1. Using a #2 Phillips or a flathead screwdriver, reattach the yellow and black 24 VDC wires to the power supply.
   1. The yellow wire should be connected the outer terminal.
   2. The black wire should be connected to the inner terminal.
   3. Ensure the screws are tightened securely

2. Using a #1 Phillips screwdriver, reattach the yellow/green ground wire.
3. Reconnect the 120 VAC connector to the power supply.
   • Ensure to the connector is seated properly and clicks into place.

4. Reinstall the 24 V Power Supply into the PCB housing.
