10. REFRIGERANT LEAK DETECTION FUNCTION
■
System operation after refrigerant leak detection:
• Indoor unit starts diffusion operation by high fan speed.
• Due to safety reasons, a remote controller cannot stop this operation.
•
Indoor unit indicates Error code A8 (TIMER lamp [8], OPERATION lamp [10]).
[ ]: Number of flashing
• Indoor unit makes a warning beep.
(The beep stops by pressing [START/STOP] of the remote controller or [MANUAL
AUTO] on the indoor unit.)
• System stops the cooling/heating operation. Forced cooling operation is not available.
