Check the damage of compressors, including the number of damaged compressors, positions and
models.
After confirming the compressor information, remove the compressors and confirm the oil quality. If
the oil is clear with no impurity, it can be considered that the oil in the system is not polluted. When the
valves and oil passages of the unit are normal, only the compressors need to be replaced.
