    2. IMPORTANT:
    • If power is interrupted prior to the recording of the 7-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 the repair order.
