SU 2.0 Install Diagnostics - Chiller Fan Current Too Low/Not Connected, or Too High

Updated

Overview

This diagnostic test confirms if the compressor fan current is within expected ranges.  A failure of this diagnostic test could indicate an issue with the chiller power harness, wiring connections, or with the chiller fan itself, and will block continuing with installation until resolved. 

Power Supply Voltage Test Lower Bound Test Upper Bound
North America - 120V <150 mA >350 mA
International - 240V <80 mA >250 mA

Troubleshooting

  1. Confirm there is adequate ventilation behind the machine. 

    • The Bevi 2.0 requires a minimum distance of 2” behind the machine to allow for ventilation. 

  2. Confirm the compressor fan is running.  

    • Restart the diagnostic test
    • While the diagnostic test is running, confirm the compressor fan at the bottom on the back of the Bevi is moving air out the back of the unit
    • If the fan is running, skip ahead to step 6. 
    • If the fan is not running, continue to step 3.

WARNING
warning electric shock hazard yellow caution.png
HAZARDOUS VOLTAGE (120 V / 240 V).
CONTACT MAY CAUSE ELECTRICAL SHOCK AND INJURY. 
DISCONNECT POWER BEFORE SERVICING.

WARNING: The next steps involve working with the live 120VAC power cable. Disconnect power to the machine prior to handling.  Powering off the machine will restart the installation process when powered back on. 

  1. Power off the Bevi and unplug the power cord. 

  2. Remove the bottom panel from the back of the Bevi.  

    • Loosen the 4 screws in the corners of the panel.
    • Lift the panel up to unhook from the screws, and remove.
    • Place the panel to the side.

  1. Confirm that the Compressor Fan power wires are connected. 

    • The compressor fan is located at the bottom on the back of the Bevi.
    • Check and confirm the two power wires are connected to the fan. 
    • If not, connect both wires to the fan. 
      • The fan does not have any polarity, so as long as both wires are connected it will spin the correct direction.  
    • Plug in the power cord and power on the Bevi. 
    • Repeat the installation diagnostic test. 
      • If the test passes, reinstall the back panel and continue with installation. 
      • If the test fails again, continue to step 6.

  1. Power off the Bevi and unplug the power cord. 

  2. Remove plastic top cover from the Bevi.

    • Open door
      • If the door is not already open, touch “Open Door” in the upper right corner of the screen.
    • Remove the 3 screws from the base of the cover.
    • Lift the cover off and place to the side.

  1. Remove the top and center panels from the back of the Bevi

    • Loosen the screws securing the panels. 
    • Lift the panel up to unhook from the screws, and remove.
    • Place the panels to the side. 

  1. Check the chiller power cable connection at the Power Module

    • On the left side of the power module, locate the large white 120v chiller power connector.
    • Inspect connector and wires for any visible damage.
    • Check and verify that the connector is fully seated.
    • Disconnect, and reseat the chiller power cable.  
      • Ensure the connector is fully seated and clicks into place.

  1. Check the chiller power cable connection at the Chiller

    • Locate the large black connector for the chiller power harness. 
      • This is located on the left side of the plumbing shelf, just above the chiller
    • Inspect connector and wires for any visible damage
    • Check and verify that the connector is fully seated
    • Disconnect, and reseat the chiller power cable.  
      • Ensure the connector is fully seated and clicks into place.

  1. Inspect the length of the chiller power harness between the Power Module and Chiller.  

    • Inspect for any cuts, knicks, or abrasion on the wiring.  

  2. Plug in the Bevi and Power on. 

    • Proceed through installation to get back to the Diagnostic Test. 

  3. Repeat Diagnostic Test

    • If the test passes, reinstall the back panels and top cover.
