[Anomaly in compressor starting]
Error display :
E59
•
Display conditions
(1) The error occurs when the compressor wouldn’t operate after
attempting to start 2 times by 7 times.
(2) Remote controller reset is possible after 3 minutes have passed.
Note (1) If the test operation is repeated 2 or 3 times, the liquid
refrigerant inside the compressor may be expelled from the
compressor may recover from its starting anomaly.

Display conditions
(1) The error occurs when the compressor wouldn’t operate after
attempting to start 10 times by 2 sets.
(2) Remote controller reset is possible after 3 minutes have passed.
Notes (1) The winding resistance is 0.4
Ω
or more at 25°C.
(2) If the test operation is repeated 2 or 3 times, the liquid
refrigerant inside the compressor may be expelled from
the compressor may recover from its starting anomaly.
Note (1) Check if the power supply system is normal.
