3.2.2 Refrigerant Oil RB75EA

The refrigerant oil is RB75EA. A sufficient amount of refrigerant oil has been filled
in the indoor compressor before delivery to ensure the reliable running of a 60 m
long pipe. Additional refrigerant oil is not required during onsite installation. When
the compressor is damaged, refrigerant oil has been filled in the compressor
before the compressor is replaced. Additional refrigerant oil is not required during
replacement. Add refrigerant oil based on the actual situation only when the
refrigerant oil leaks and the compressor does not need to be replaced.
