- 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.
Inspect for leakage again.
- If there is no refrigerant leakage, perform the procedure from the evacuation again. (See Charging Preparation .)
- If there is refrigerant leakage, inspect the refrigeration system following the symptom troubleshooting procedure. (See FOREWORD [FULL-AUTO AIR CONDITIONER] .)
