The oil level was low due to a leak in the evaporator so i decided to change the oil from mineral to polyol ester oil made by Emkarate SW32MAF which is a specific oil for Copeland compressors.

The oil change from mineral to synthetic helps get the system ready for a change to HFC refrigerants once R22 becomes unavailable.

    I made the sight glass tool out of an impact grade socket and a bit of unistrut! Couldn't get the proper tool from the wholesalers. Yeah i'd have had to disconnect it and tip it out the suction port otherwise!

    Hi Alan,

    The dimples in the glass should dissapear once the oil covers them, think its designed to make the level easier to see, this one is dirty despite cleaning (old system)
    That is pretty much the procedure, it was pumped down so no refrigerant was released,oil changed, then leak checked with nitrogen prior to vacuuming and letting the refrigerant back in and running up.

    The oil sight glasses are more common on the refrigeration spec compressors. The level was too low plus i wanted to change it from mineral to POE oil so its a step ahead when R22 runs out!

  4. heavydiesel says:

    It would take three or four changes with a good bit of run time inbetween to get the mineral oil content low enough to change from hcfc or cfc to hfc refrigerants. Idealy it wants to be below 3% mineral oil. Depending on the type of system and pipework configuration you may be able to get away with more mineral oil mixed in with the poe but below 3% is a good figure to aim for.
