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.
- 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.
- Inspect for leakage again.
- If there is no refrigerant leakage, perform the procedure from the vacuum pump operation again. (See Evacuation .)
- If there is refrigerant leakage, inspect the refrigeration system following the symptom troubleshooting procedure. (See FOREWORD [FULL-AUTO AIR CONDITIONER] .) (See FOREWORD [MANUAL AIR CONDITIONER] .)
- Disconnect the quick couplers from the charging valves.
- Install the caps to the charging valves.
