Kirloskar Chillers Searchable Fault & Error Code Guide
| Code | Condition / Symptom | Engineering Diagnosis & Fix |
|---|---|---|
| Tube Scaling | High condensing approach temperature (>3.5°C over cooling water leaving temp) | Mechanically brush and chemically circulate descaler in condenser bundle. |
| Oil Safety Switch Trip | Differential pressure across lube circuit dropped below safety limit | Replace oil filter cartridge, check oil level in sight glass, test oil pump. |
| Freeze Stat | Leaving chilled water temperature dropped below 3.5°C | Verify secondary load flow, tune capacity slide valve unloader sequence. |
| Phase Reverse | Power supply phase sequence inverted | Swap incoming supply phases at main MCC breaker, verify phase monitor relay. |
