Leak Test

  1. Inspect for gas leakage using the gas leak tester.
    • If there is no leakage, go to Step  3.
    • If leakage is found at a loose joint, tighten the joint, then go to the next step.
  2. Inspect for leakage again.
    • If there is no refrigerant leakage, perform the procedure from the evacuation again. (See Evacuation .)
    • If there is refrigerant leakage, inspect the refrigeration system following the symptom troubleshooting procedure. (See FOREWORD [FULL-AUTO AIR CONDITIONER] .)
  3. Disconnect the quick couplers from the charging valves.
