- Can doubt that is blocked if oil separator capillary tube temperature is low after refrigerant outlet temperature of compressor, in
driving, rises.
( Models with 2 compressors, oil separator capillary tubes are crossing each other.)
- Confirm that is blocked in stationary state through nitrogen pressurization availability.
