  1. Turn the main function switch to the CODE position.

    Important: 

    • If power is interrupted prior to the recording of the seven-character code, the code will be lost and the flow rate test will need to be repeated.
    • The flow test must run for a minimum of 8-10 seconds and be above 0.5 gpm for a code to be generated.
  2. Record TESTED flow rate, temperature, cycle and seven-character flow code information on repair order.
