Removal and Replacement Steps:

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

Task 1: Disconnect power from Standup 2.0 

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

Task 2: Remove the center panel from the back of the Bevi.

1. 1. Loosen the screws in the corners of the panel.
   2. Lift the panel up to unhook from the screws, and remove.
   3. Place the panel to the side. 

Task 3: Disconnect the Heater Power Cable. 

1. 1. Locate the large red connector for the heater power cable. 
      • Disconnect the heater power cable.
      • Press the two lock latches on the sides to release the connector. 
   2. Once the heater power cable is disconnected, plug in the power cord and power the Bevi back on.  

Task 4: Flush the hot water out of the Heater. 

1. 1. Once the screen has powered on, navigate to the Troubleshooting Tools Screen.
      • Touch the Service button in the top left corner of the main dispense screen.
      • Touch "Start Service" on the right side of the screen.
      • Enter the access code “1986”.
        • The door should open. If it doesn't, press the “Open Door” button.

2. From the service panel, touch "Alerts and Maintenance, then "Troubleshooting Tools" 

3. Place a large container under the nozzle. 
4. Using the Pour button in the lower left corner of the screen, continuously pour HOT water to flush the heater.  CAUTION: The water dispensed in this step will be very hot. 
   • The heater is no longer powered, so this will flush the heater with cold water to lower the temperature so it is safe to handle.  
   • Continue pouring cold water until the Heater Temp is below 30°C.
     • If Heater temp data is reading “NaN”, then the heater temperature sensor is not reporting; you will need to continuously flush hot water until the water no longer is dispensing hot. 

Task 5: Depressurize the water system. 

1. 1. Close the buffer tank. 
      • With the door open, access the Buffer Tank shut off through the hole above the filter. 
      • Turn the valve ¼ turn clockwise to close the Buffer Tank.
        • The valve should be pointed out of the access hole when closed. 

2. Turn off the water source to the Bevi.  
   • Locate the shut off valve on the water source behind the machine and turn it off. 
3. On the screen, pour COLD water until no water is coming out of the nozzle.  
   • Continue dispensing until the Internal Water Pressure is at or below 0psi. 

Task 6: Remove the Demand Pump.

In order to access the heater, you will first need to remove the demand pump.  

1. Turn off the Bevi and unplug the power cord. 
2. Disconnect the inlet and outlet tubes from the demand pump. 
   • Remove the red locking clips, and disconnect the tubing from the push to connect fittings on the pump. 
   • Note the routing of the tubes for reinstallation.  

3. Using a long-bladed #2 phillips screwdriver, remove the 4 mounting screws at the base of the demand pump.  
   • Note: The two rear mounting screws are not easily visible, and can be difficult to access without a proper length screwdriver.  
4. Remove the demand pump to access the heater.  
   • For easy storage, you can hook the demand pump bracket between the plumbing shelf and chiller while you work on the heater.  

Task 7: Remove the Heater.  

1. 1. Disconnect the hot water tube from Manifold 2.
      • Using a pair of pliers, compress the spring clamp and slide it down the tube. 
      • Gently twist and pull to disconnect the hot water tube from the barbed fitting on Manifold 2. 

2. Disconnect the stem elbow from the metal push-to-connect fitting on top of the heater.  

3. Disconnect the heater temperature and level sensor cable. 
4. Remove the 11/32” nut and disconnect the ground wire.  
   • Reinstall the nut to secure the remaining ground wires. 

5. Using either a #3 Phillips screwdriver or 3/8” wrench, remove the two mounting screws from the base of the heater.  
6. Remove the upper mounting screw at the top of the heater bracket.  

7. Carefully slide the heater out and remove it from the machine.  
   • Once the heater is removed, it can be drained out of the top fitting. 

Task 8: Installing the replacement heater. 

1. 1. Carefully slide the heater into place. 
      • The base of the heater bracket has two locating tabs that slot into holes in the plumbing shelf.  
      • Ensure the heater sensor and power cables are not pinched and are accessible once heater is in place. 

2. Reinstall the 3 mounting screws. 
3. Connect the ground wire. 
   • Ensure the other two ground wires remain in place. 
4. Connect the heater sensor and power cables. 

5. Connect the heater inlet tube to Manifold Two. 
   • Secure the tube with the metal clamp, ensuring that the clamp is over the barbed fitting.  
6. Connect the hot water output tube to the metal push-to-connect on top of the heater.  

Task 9: Reinstall the Demand Pump. 

1. 1. Reinstall the demand pump onto the plumbing shelf.  
      • It is helpful to insert the two rear mounting screws into the rubber grommets prior to placing the pump on the shelf.  
      • Install and tighten the remaining screws.  

2. Reconnect the inlet and outlet tubes to the demand pump.  

Task 10: Fill and test the Heater.  

1. 1. Plug in the power cord and power on the Bevi. 
   2. Navigate back to the Troubleshooting Tools menu. 
   3. Fill the Heater.  
      • Place a container under in the dispense area and pour hot water until it begins to dispense from the nozzle.
      • Once water is dispensing from the nozzle, confirm in the Data section that the heater is reporting as full. 
   4. Verify heater temperature is reading correctly. 
      • Note: The heater is not yet up to temperature so it will likely be highlighted in red, this is normal.

5. Using the Controls menu, turn on the heater.
   • Confirm heater current is between 6.5-7.5 amps when on.  
   • If you do not see heater current when it is powered on, turn off the Bevi and unplug the power cord and confirm the heater power cable is connected properly. 

Task 11: Test the machine and reinstall the back panel.  

1. 1. Once the heater has been tested, exit the service panel and go back to the main dispense menu. 
   2. Test all functions of the machine to ensure they are working properly. 
   3. Inspect the plumbing shelf to ensure there are no leaks present. 
      • If any leaking is found, recheck that all tubing connections are fully seater.  
   4. Reinstall the rear panel.
