Remove and Replace Procedure

Task 1: Depressurize the water system.

1. Turn off the water source to the Compact Chiller.
   • Locate the shut off valve for the water supply, and turn 90* to the closed position.

2. Open the front access panel.
3. Turn off the Buffer tank.
   • Rotate the shut off valve to the CLOSED position.

4. 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.

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

6. 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.

6. 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.

Task 5: Remove the left side panel.

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

Task 6: Remove the PCB panel.

1. Using a #2 Phillips screwdriver, loosen the screw securing the PCB panel on the left side of the chiller.
2. With the screws fully loosened, lift the panel to release the lower locating tab and remove.
3. Place the panel to the side.

Task 7: Remove the Demand Pump.

1. Disconnect the Demand Pump cable from the BUC Board.
   1. In the PCB panel, locate the Demand Pump connector on the left side of the BUC Board.
   2. Depress the lock-latch on the connector and carefully disconnect from the BUC Board.

2. Carefully cut the mountable zip tie securing the demand pump cable on the left side of the PBC Panel.
3. Pull the cable connector out of the PCB panel through the access hole.

CAUTION: Take care to not nick or cut any of the wiring when cutting the zip tie.

4. Disconnect the two tubes from the "Y" fitting downstream from the pump.
   1. Remove red locking clips from the push-to-connect fittings.
   2. Take care not to drop any of the clips down into the ice bank.

NOTE: Chillers manufactured after November 2025 may not have red clips on the internal water fittings.

5. Disconnect the 1/4" stem elbow from the input side of the demand pump.

6. Using a #2 Phillips screwdriver, remove the Demand Pump mounting screws.
   1. There are 4 screws, two on each side behind the Demand Pump.
   2. Once the screws are fully unthreaded from the chiller, they can remain in place in the rubber grommets.

7. Disconnect the 1/4" tube from the output side of the Demand Pump.
   • Once the mounting screws are removed it allows some movement of the pump to get more access to the fitting.

8. Carefully remove the Demand Pump and cable out from the left side of the chiller.
   1. Lift the pump up slightly, and tip the bottom out first.
   2. Rotate the pump counter clockwise as you work it out of the chiller.
   3. Take care to not pull on any of the surrounding cabling, and not to damage the foam insulation on the ice bank during removal.

9. Remove the 4 screws from the rubber grommets on the pump bracket.
   • These will be reused to install the new pump.
10. Using a Phillips screwdriver, remove the mountable zip tie that was cut in the prior steps.

Task 8: Install the new Demand Pump.

1. First, install a replacement mountable zip tie.
2. Unbox the new pump.
3. Insert the 4 mounting screws into the rubber grommets.
4. Carefully install the pump into place in the chiller.
   • Tip the pump and work into the chiller top first, then rotate into place.

5. Connect the 1/4" tube with "Y" fitting to the output of the demand pump.
6. Reconnect the Water Coil and Ambient out tubes to the "Y" fitting.

7. Reconnect the 1/4" stem elbow to the input fitting on the pump.

8. Using a #2 Phillips screwdriver, tighten 4 mounting screws to secure the pump in place.
9. Feed the cable through the access hole into the PCB panel.
10. Reconnect the Demand Pump cable to the BUC Board.
    • Ensure the connector is fully seated and clicks into place.
11. Secure all cabling in the new mountable zip tie.

Task 9: Reinstall the Chiller.

1. Reinstall the left side panel, and the PCB 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.
   • 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.
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.
   3. Turn on the water supply.
5. If it was closed, open the Buffer tank.
6. Power on the chiller.

Task 10: Test the Demand Pump.

1. Once powered on, navigate back to the Troubleshooting Tools
2. From the "Controls" menu, turn on the Demand Pump.
   1. Confirm you hear the demand pump running.
   2. If it is not, remove the PCB panel and check the connection at the BUC Board.
