When compressor is in operation, the outlet of compressor always has lots of refrigeration oil. We need to install an oil separator between compressor and condenser to separate the refrigeration oil and refrigerants in order to prevent the refrigerant oil flow to system with refrigerants to interfere the condenser’s heat function and evaporator cooling function. Then the oil will flow back to the compressor crankcase. Oil-return device operates on the ball valve moving on the bottom of oil separator and the sufficiency of oil in compressor and let the compressor reach its best cooling performance
We need to pre-charge the oil before installing oil separator. The oil we charged should be same as the oil in the compressor crankcase
