Leak Test

CAUTION:
  • Looking directly at a florescent agent-detecting UV black light may cause injury to the eyes. Do not look directly into the light of a florescent agent-detecting UV black light.
NOTE:
  • Because florescent agents are in the refrigeration cycle, the leak test can be performed with a florescent agent-detecting UV black light.
  1. Inspect for gas leakage from the piping connection using a gas leak detector or a florescent agent detecting UV black light.
    • 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 [CLIMATE CONTROL SYSTEM] .)
  3. Disconnect the quick couplers from the charging valves.
