compressor fails.
<Alarms Corresponding to Inverter Compressor Failure>
04: Abnormal Communication between inverter PCB and Outdoor Unit PCB
06: Abnormality of Inverter Voltage
23: Abnormality of Discharge Gas Thermistor
48: Activation of Overcurrent Protection Device
51: Abnormality of Inverter Current Sensor
53: Inverter Error Signal Detection
54: Abnormality of Inverter Fin Temperature
55: Inverter
Failure
(a) Procedures
1. Turn OFF all the main switches of outdoor and indoor units.
2. Disconnect the wiring (U, V, W) of diode module.
Â
1
(Insulate the disconnected terminals.)
3. Turn DSW5-No.1 ON to stop the inverter compressor operation. Not all the compressors in the
failed outdoor unit will stop the operation. If two compressors are stopped simultaneously, the
stoppage cause is supposed to be d1-30.

4. Turn ON the power supply.
5. Start the operation with the wired controller.
PROCEDURE REMINDERS:
• Measure the insulation resistance of the malfunctioning compressor.
Do not perform the emergency operation when the insulation resistance is 0
:
.
The other compressors may be damaged because there is a possibility that refrigerant oil is oxidized.
• In this emergency operation, compressor frequency cannot be controlled normally.
Therefore, an alarm code “07”, “43”, “44”, “45” or “47” may be indicated on the LCD.

• This operation is a temporary emergency operation when the compressor is damaged. Therefore,
replace it with a new one as soon as possible.
• Turn OFF DSW5-No.1 and No.2 of the outdoor unit PCB after replacing the compressor.
If this setting is not performed, the compressor will be damaged.
