[Guide] Standup 1.5 Remove and Replace - Thermostat

Overview 

This guide will walk you through step by step process to remove and replace the thermostat in the Bevi Standup 1.5.

Required Tools and Materials

• 720-0157 - Thermostat
• #2 Phillips screwdriver
• #3 Phillips screwdriver
• Small bucket

Removal Procedure

Task 1: Depressurize the water system. 

1. Power off the Bevi. 
   • Turn off power to the unit by flipping the switch on the back near where the power cord connects. 

2. Open the door.
3. Close the buffer tank.
   • The buffer tank valve is located behind the CO2 tank.  
     Turn the valve 1/4-turn clockwise to close (pointed forwards/perpendicular to the flow of water).

4. Power off Chiller. 
   • The power switch is located on the right side, towards the rear of the chiller.  

5. Using Diagnostic Lines, depressurize the Still and Sparkling outputs. 
   • Remove the Still and Sparkling Diagnostic lines from the grommets at the base of the door.  
   • Place both lines into a bucket. 

3. Open the Still Diagnostic Valve until completely depressurized, then close the valve.
4. Open the Sparkling Diagnostic Valve until only CO2 is coming from the line, then close valve.

5. Turn off the CO2 tank. 
6. Reopen the Sparkling Diagnostic Valve again until all CO2 pressure is released. 
7. Once all CO2 pressure is released, close the valve.  

Task 2: Remove the chiller.

8. Remove the bracket at the base of the chiller
   • Using a #3 Phillips screwdriver, remove the two screws securing the bracket. 
   • Note: If the screws are corroded and you are unable to remove, contact Bevi Support at 866-704-BEVI before proceeding to next steps.  

9. Disconnect all inputs and output tubes from the chiller. 
   • Remove red locking clips from each fitting. 
   • Disconnect Water In, Ice Bank Fill, CO2 In, Sparkling Out, and Still Out tubes from the front of the Chiller. 
     • It is much easier to disconnect the tubing from the 90° elbow push-to-connect fittings. Leave the elbow fittings connected to the chiller.  

10. Carefully slide the chiller out of the Bevi and place on the ground.  
    • Take care to keep the chiller as flat and level as possible.
    • Note: It is possible that some water may spill out of the ice bank while removing the chiller.  

Task 3: Remove the sheet metal cover.

1. Using #2 phillips screwdriver, remove the 10 screws securing the cover to the chiller.  
   • There are 6 screws on the front, and 4 on the back.  

2. Lift the cover off of the chiller.  
   • You may need to pull the side panels out slightly to separate the cover from the Chiller.  

Task 4: Remove the Thermostat. 

1. Locate the thermostat on the backside of the front panel of the chiller. 
2. Disconnect the 3 wires from the thermostat. 
   • TIP: It can be helpful to take a photo of the wiring connections prior to disconnection to reference for reinstallation. 

3. Remove the two screws securing the Thermostat to the front panel.  

4. Remove the two screws securing the thermostat bracket to the ice bank.  
5. Carefully pull the bracket up and out of the ice bank. 

6. Remove the thermostat tube from the rubber grommet on the bracket. 
7. Cut the zip tie and remove the thermostat from the bracket.  

Task 5: Install the new Agitator. 

1. The new thermostat will come coiled up in the box. 
2. Carefully uncoil the thermostat tube. 
   • CAUTION: Take care not to kink the tube, as this can damage the thermostat.  
3. Install the new thermostat onto the bracket. 
   • Route the tube through the grommet, and install a new zip tie to secure the probe to the bracket. 

4. Reinstall the bracket into the ice bank. 
   • Note: The bracket and thermostat are a snug fit, carefully work it into place down in the ice bank. 
5. Rout the thermostat tube back the same way the old one came out. 
6. Mount the thermostat to the front panel and reinstall the two screws. 

7. Reconnect the three wires to the thermostat. 
   • See image below for wiring connections. 

8. Set the thermostat to 5: 
   • On the front of the chiller, adjust the thermostat set point to 5. 
     • Turn the dial counterclockwise to “OFF”, then turn it back clockwise to 5. 

Task 6: Reinstall the Chiller. 

1. Place the cover back onto the chiller. 
   • Reinstall all 10 screws to secure the cover to the chiller. 
2. Lift the Chiller and slide into the base of the Bevi. 
   • The chiller feet need to slide into the slots of the rear bracket for proper placement.  

3. Reinstall chiller bracket. 
4. Reconnect all tubing to the front of the chiller.  
   • Ensure tubes are fully seated into push-to-connect fittings. 
   • Reinstall red locking clips.  

Task 7: Top off the Ice Bank

1. Power on the Bevi machine.  
2. Turn on then supply water. 
3. Top off the Ice Bank.
   • During the removal and reinstallation process, it is likely that some water will spill from the ice bank. 
   • From the Service Panel, touch “Advanced” in the upper right corner of the screen. 
   • Touch “Open Inlet” in the lower left of the Advanced menu.  
     • You should hear the inlet solenoid click open. 

4. With the open end of the overflow tube draining straight down into a collection container, open the ice bank fill valve to begin topping off the ice bank. 
   • Open the ice bank fill valve until water begins to flow from the overflow tube.
   • As soon as water is flowing from the tube, close the ice bank fill valve.  
   • Allow any excess water to drain from the tube, and resecure the open end of the tube into the clips.  

4. Open Buffer Tank. 
   • Turn the Buffer Tank valve counter clockwise so it is pointed upwards to open.   

5. Turn on the CO2 tank.  
6. Plug in Power Cable and power on the Chiller.  

Task 8: Test Functionality

1. Exit the Service Panel to the main dispense screen. 
2. Pour both still and sparkling water to verify Bevi is dispensing properly.  
3. Check for any leaks. 
   • If any leaks are found, inspect all connections and ensure tubing is fully seated.  
4. Launch Incubation.
   • After the thermostat is replaced, it is important to launch Incubation Mode to allow the chiller to cool down to proper temperature. 
   • Go back to the Service Panel “Advanced” menu. 
   • Touch “Start Incubation”

5. Close and lock the door.
