Leak test
WARNING: This page is about a different variant/trim than selected.
CAUTION:
- Looking directly at a fluorescent agent-detecting UV black light may cause injury to the eyes. Do not look directly into the light of a fluorescent agent-detecting UV black light.
NOTE:
- Because fluorescent agents are in the refrigeration cycle, the leak test can be performed with a fluorescent agent-detecting UV black light.
- Inspect for gas leakage from the piping connection using a gas leak detector or a fluorescent agent-detecting UV black light.
- If there is no gas leakage, go to Step 3.
- If there is gas leakage, tighten the piping connection to the specified torque, then go to the next step.
- Inspect for gas leakage from the piping connection again using a gas leak detector or a fluorescent agent-detecting UV black light.
- If there is no gas leakage, perform the procedure from the vacuum pump operation again.
- If there is gas leakage, inspect the refrigeration system following the symptom troubleshooting procedure.
- Remove the quick couplers from the charging valves (high/low pressure).SYMBOL AND CONTENT DESCRIPTION
