2. Error detection method
3. Condition of error displayed
4. Presumable cause
• Fuse blown
• Noise filter anomaly
• Anomalous connection of
wire between PCBs
• Indoor unit control PCB anomaly
• Remote control anomaly
• Breakage of connecting wires

• Outdoor unit control PCB
anomaly
Note:
(1) When anomaly occurs during establishing communication between indoor and outdoor unit, error code E5 is displayed (outdoor red LED
flash 2-times).
In case of E5, the way of troubleshooting is same as above mentioned (except for checking of connecting wire).
When reset the power after E5 occurs, if this anomaly recurs,
