中文
含义
可燃制冷剂泄漏报警。系统检测到R32/R290制冷剂浓度异常升高，达到泄漏报警阈值。制冷剂泄漏在有火源时存在燃烧或爆炸风险，需立即处理。
常见原因
- 制冷系统管路严重破损大量泄漏
- 室内机蒸发器或室外机冷凝器腐蚀穿孔
- 维修后接口未正确密封
- 运输或安装过程中管路受损
- 化学腐蚀性环境导致铜管加速腐蚀
自助排查
- 立即关闭空调电源，禁止按任何开关或插拔电源
- 打开门窗保持通风，降低室内可燃气体浓度
- 远离泄漏区域，禁止明火、吸烟或操作电器开关
- 立即联系专业维修人员处理，切勿自行排查
English
Meaning
Flammable refrigerant leak alarm. The system detects an abnormally high concentration of R32/R290 refrigerant, reaching the leak alarm threshold. Refrigerant leaks pose a fire or explosion risk in the presence of an ignition source — immediate action is required.
Common Causes
- Major refrigerant line rupture causing rapid large-scale leakage
- Corrosion pinholes in the indoor evaporator or outdoor condenser coils
- Improperly sealed service connections after previous maintenance
- Piping damaged during transport or installation
- Chemically aggressive environment accelerating copper tube corrosion
Self-Check Steps
- Immediately disconnect the AC power — do not touch any switches or unplug the unit
- Open windows and doors for ventilation to reduce indoor gas concentration
- Stay away from the leak area; no open flames, smoking, or electrical switching
- Contact a professional service technician immediately — do NOT attempt DIY leak investigation
