  1. From the Troubleshooting Tools screen, press and hold “Pour” for sparkling water again until all CO2 pressure is released.

Task 3: Disconnect the Trunk Line from the Chiller Outputs.

NOTE: If you did not depressurize the water lines as instructed in Task 2, the trunk line will still be pressurized and will spray water when disconnected.

Make sure Task 2 is fully completed as shown before proceeding.
  1. Remove the filter by turning counterclockwise to disconnect. Place to the side. 
      • Removing the filter allows for easier access to the Trunk Line connections.  

  1. Remove the CO2 tank from the Bevi and place to the side. 
    • The high pressure CO2 hose does not need to be disconnected from the tank.
    • Place the CO2 tank to the side. 
       🪄 TIP: The CO2 tank can be used to prop the door open while you work.  
  2. Disconnect the Trunk Line from the Chiller. 
    • Remove the red locking clips from the sparkling out, cold out, and recirculation lines. 
    • Disconnect the elbows from the push to connect fittings on the chiller.
      • Do not disconnect the tubes from the 90° elbow fittings, as the elbows will not fit through the panel when removing the chiller.  
      • Note the orientation of the tubes for reinstallation.

Task 5: Remove the Chiller from the Bevi. 

  1. Remove the two mounting screws from the front of the Chiller.  
    • One screw is located just to the left of the chiller output connections.
    • The second screw is located on the right side just above the vent. 
    • Using a #2 Phillips screwdriver, remove the mounting screws.
      • Place the screws aside in a safe place, they will be reused during reinstallation. 

  1. Roll the Bevi machine out and away from the wall to access the back panels. 
  2. Remove the center and bottom panels from the back of the Bevi.  
    • Both the center and bottom panels have 4 screws in the corners securing them to the Bevi. 
    • Loosen the 4 screws in the corners of each of the panels.
      • The mounting screws do not need to be fully removed. 
    • Lift the panel up to unhook from the screws, and remove.
    • Place the panels to the side.

  1. Disconnect the three input tubes from the top of the Chiller. 
    • Remove the red locking clips and set to the side.
    • Disconnect the Ice Bank Fill, Water In, and CO2 in tubes from the push to connect fittings. 

  1. At the base of the chiller, remove the two bottom mounting screws.  
    • The screws are located at the base of the machine, on either side of the compressor fan.  
    • Use either a #3 Phillips screwdriver or 3/8” wrench to remove the screws.  
      • Place the screws aside in a safe place, they will be reused during reinstallation. 

  1. Disconnect the Chiller electrical connections.  
    • There are 3 electrical connections for the Chiller located on the left side of the plumbing shelf.

    • Disconnect all three cables.  
      • The cables have lock latches; press down the latch to release the connector and disconnect. 

  1. Slide the Chiller out of the back of the Bevi.
    • Grabbing the top and middle of the Chiller, gently slide it out from the back of the machine.
    • Once the Chiller is half way out, you can grab the handles on the sides at the top. 
    • Completely remove the chiller from the Bevi and place on the floor. 

If this Chiller is being replaced, you must drain the ice bank before transporting it. On Gen 2 Chillers (white plastic top), there is a dedicated hole for transfer pump tube (pictured below).

Skip this step if you will reinstall the same chiller back into the same machine.

  1. Using a transfer pump, drain the water from the ice bank.
    • Insert the feed tube from the pump down to the bottom of the ice bank at the center of the coil. 
    • Pump the water out into a bucket. 

  

Task 6: Reinstall the Chiller. 

  1. Lift the Chiller by the handles and slide it into the back of the Bevi.  
    • Once the Chiller is half way into the machine, you can push it the rest of the way in from the back. 
  2. Reconnect the 3 Chiller electrical connections
    • Reconnect the Chiller Power Cable.
    • Reconnect the Chiller Sensor Harness.

      • Reinstall the red locking clips.  

  1. Reinstall the two mounting screws at the base of the Chiller.  
    • You may need to adjust the position of the Chiller slightly to align the mounting holes.  
    • Use a #3 Phillips screwdriver or 3/8” wrench to tighten the screws.  

  1. At the front of the Bevi, reconnect the Trunk Line tubes.  
    • From left to right, reconnect the Sparkling Out, Cold Out, and Recirculation Lines.

    • Rotate the Buffer Tank valve counterclockwise.
      • The valve will be pointing to the right of the Bevi when in the open position. 
  5. Fill the Ice Bank. 
    • Under “Controls”, find “Fill Ice Bank” in the Chiller section.  
    • Press “START”
      • The Inlet and Ice Bank Solenoids will open and begin to fill the Chiller.
      • While the Ice Bank is filling, inspect the plumbing shelf and base of Chiller at the back of the Bevi for any leaks. 
      • If there are any leaks, recheck tubing connections.   
      • Once the Ice Bank is full, the fill solenoid will automatically close.  
    • Under “Data”, find the Chiller section. 
      • Verify that Chiller Full states YES. 
      • If the chiller fails to fill, ensure filter is installed, water source is open, and there is no water present in the base of the Bevi.  

  1. Fill the Carbonator.  
    • In the lower left corner of Troubleshooting Tools, press “Pour” to dispense sparkling water for 5 seconds, then release and wait 20 seconds. 
      • The Demand Pump will run to attempt to refill the Carbonator.  
    • Repeat the 5 second dispense with 20 second pause until Carbonator Full switches from NO to YES in the Chiller Data.  
      • This can take 5-10 cycles to fill. 

  1. Dispense COLD water. 
    • In the lower left corner of Troubleshooting Tools, press “Pour” to dispense cold water to purge any trapped air from the system.

    • North American (120 V): Compressor current should read between
      2 A – 2.5 A. 
    • UK/Europe (240 V): Compressor current should read between 0.6 A – 1.3 A. 
  3. If the compressor current is outside of expected ranges, power off the Bevi and confirm the 120/240 VAC Chiller Power Cable is properly connected. 

Task 10: Resolve any Machine Alerts. 

  1. At the top of the Troubleshooting Tools screen, press “Back to Alerts” 
  2. Troubleshoot and resolve any active Machine Alerts.  

Task 11: Reinstall the Back Panels.

  1. Reinstall both panels on the back of the Bevi. 
    • Tighten the 4 screws for each panel.
