    Hitachi RCU2e180AG2 Oil change

    Hi , chasing some information on carrying out an oil change on a Hitachi 50-ASC-Z compressor. I can't see anyway of draing and adding oil without removing the bottom/ side plate and drilling and tapping a thread to install an oil port. As there are no service valves on this chiller I will need to recover complete chiller charge.
    Any thoughts.?
    Thanks

    I have not worked on that compressor, but it has an oil heater, remove that to drain...

    Why does the oil have to be changed?
