Refer to section - 5 - "Inverter" under part [3] "Trouble shooting principal parts" for error codes related to the
inverter.(page 69)
1. Error Code
5201
High pressure sensor failure (63HS)
2. Error definition and error detection method
If the high pressure sensor detects 0.098MPa [14psi] or less during the operation, the outdoor unit stops once,
turns to antirestart mode for 3 minutes, and restarts after 3 minutes when the detected high pressure sensor is
0.098MPa [14psi] or more.
If the high pressure sensor detects 0.098MPa [14psi] or less just before the restart, the outdoor unit makes an
error stop, and the error code "5201" will appear.
During 3-minute antirestart mode, preliminary errors will be displayed on the LED display.
A error is not detected for 3 minutes after the compressor start, during defrost operation, or 3 minutes after
defrost operation.
