Has anyone changed the oil using the bolt on the bottom of the oil reservoir? it seems a little tight to the condenser, it seems logical. I drained the oil using the service valve with the 3/8 port and got 4.5 gallons out. also does anyone know the time line you would have to have the chiller open to the atmosphere seeing that there is POE oil here and there in the chiller piping and compressor?
The oil needed changing do to analysis
