• For this outdoor unit, by referring to the 5 LED (1 4 Red) indicator lights, self-diagnosis is possible.
• LEDs (D800 to D804) are located on the sub-control board underneath the inverter.
*1 Heat pump model only
• These LEDs do not normally light.
1.
If trouble occurs, LED goes on according to the contents of trouble as shown in the
table above.
2.
