SU 2.0 (Gen 1) Chiller Remove & Replacement Guide

Overview

This document will walk you through the step by step process to remove and replace the Gen 1 chiller in a Bevi Standup 2.0.  

Required Tools & Materials

• You will need the access codes to enter the machine and service panel
• Number 2 Phillips screwdriver
• Number 3 Phillips screwdriver or ⅜” wrench or socket
• Adjustable wrench (optional)
• Bucket (to drain line pressure)

Task 1: From the Service Panel, access the Troubleshooting Tools menu.  

Task 2: Depressurize the water lines. 

1. Turn off the water supply to the Bevi.

2. Close the Buffer Tank.
   • With the door open, access the buffer tank valve through the access hole above the filter.
   • Turn the valve clockwise to close the buffer tank.
     *The valve should be pointed forwards out of the access hole when in the closed position.

3. From the Troubleshooting Tools screen, dispense both Cold and Sparkling water.  
   • Place a small bucket or contain under the dispense nozzle.
   • In the lower left corner of the screen, press and hold “Pour” for cold water until no water is dispensing. 
   • Press and hold “Pour” for sparkling water, until only CO2 is dispensing.

4. Turn off the CO2 tank.  
   • Turn the CO2 tank valve clockwise until it stops.

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

Task 3: Power off the Bevi Machine. 

WARNING
	HAZARDOUS VOLTAGE (120 V / 240 V). CONTACT MAY CAUSE ELECTRICAL SHOCK AND INJURY.  DISCONNECT POWER BEFORE SERVICING.

1. Turn off the power switch on the top rear of the unit. 
2. Remove the power cable.

Task 4: Disconnect the Trunk Line from the Chiller Outputs.

1. Remove the Filter.
   • Turn the filter counterclockwise to disconnect, and place to the side. 
   • Removing the filter allows for easier access to the Trunk Line connections.  
2. 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.  
3. 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.

2. Roll the Bevi machine out and away from the wall to access the back panels. 
3. 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.

4. 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.

5. 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 ⅜” wrench to remove the screws.  
     • Place the screws aside in a safe place, they will be reused during reinstallation.

6. Disconnect the Chiller electrical connections.  
   • There are 3 electrical connections for the Chiller located on the left side of the plumbing shelf. 
     • 120VAC Power Cable.
     • Chiller Sensor Harness.
     • 24VDC Recircatator Power Cable. 
   • Disconnect all three cables.  
     • The cables have lock latches, press down the latch to release the connector and disconnect.

7. 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.

8. If the Chiller is being replaced, you will need to drain the ice bank before transporting it. 
   • 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. 
   • For Gen2 Chillers (white plastic top), there is a dedicated hole for transfer pump tube (pictured below).
   • If the same Chiller is being reinstalled, you do not need to drain the ice bank.

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 back 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 120VAC Chiller Power Cable.
   • Reconnect the Chiller Sensor Harness.
   • Reconnect the 24VDC Recircatator Power Cable. 
     • Ensure all connections are fully seated and lock latches clip into place.

3. Reconnect the Chiller Input tubes.  
   • Reconnect the Water In, CO2 In, and Ice bank Fill Tubes.  
     • The tubes are all unique sizes, and cannot be connected incorrectly. 
     • The tubes have insertion depth marks, ensure all tubes are fully seated into the push to connect fittings. 
     • Reinstall the red locking clips.

4. 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 ⅜” wrench to tighten the screws.

5. At the front of the Bevi, reconnect the Trunk Line tubes.  
   • From left to right, reconnect the Sparkling Out, Cold Out, and Recirculation Lines. 
   • Reinstall the red locking clips.

Task 8: Filling the Chiller. 

1. Reinstall the filter. 
   • Lift the filter into the filter head. 
   • Rotate clockwise and tighten.
2. Place the CO2 tank back into the Bevi. 
   • If the CO2 tank was disconnected, reconnect the high pressure hose and tighten the nut with an adjustable wrench. 
3. On the screen, navigate back to the Troubleshooting Tools menu.
4. Turn on the CO2 tank.
   • Turn the tank valve counterclockwise to open the tank. 
5. Place a bucket or container under the dispense nozzle. 
6. From Troubleshooting tools, pour sparkling water until CO2 is dispensing from the nozzle. 
7. Turn on the water supply to the Bevi.
8. Open the Buffer Tank. 
   • Access the Buffer Tank valve through the hole above the filter.
   • Rotate the Buffer Tank valve counterclockwise.
     • The valve will be pointing to the right of the Bevi when in the open position. 
9. Fill the Ice Bank. 
   • Under “Controls”, find the Chiller section.  
   • Press “Fill Ice Bank”
     • The Inlet and Ice Bank Solenoids will open and begin to fill the Chiller.
       1. While the Ice Bank is filling, inspect the plumbing shelf and base of Chiller at the back of the Bevi for any leaks. 
       2. 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. 
10. Fill the Chiller.  
    • 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 chiller.  
    • 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. 
11. 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.
