E: A8. Refrigerant Leakage Sensor Error (Indoor Unit) - Fujitsu AUXG07KVLA Manual

2-41. E: A8. Refrigerant leakage sensor error (Indoor unit)

Indicator Indoor unit
Detective actuator
Forecast of cause
Check point 1. Refrigerant leakage detection conditions
• When the refrigerant leakage sensor detects refrigerant.
• System stop -> Cooling/heating cannot be operated.
• Stir operation by fan -> Safety is important, and fan operation cannot be stopped.
-> Check for refrigerant leaks and take corrective action.
Check point 2. Error release condition
Power on again.
• If the power is not turned on again, the error will not be cleared even if the gas concentration
drops.
• If the refrigerant leakage is detected again after the power is turned on again, an error will occur
again.
• Replace the refrigerant leakage sensor as it will not recover if exposed to a high concentration
of gas or if exposed multiple times even if the concentration is not high.
