    York YCAV300 - Screw

    Trouble Shooting why when changing oil filter cartridge in compressor, system 1 was completly dry, no oil.
    off on HDP, Is a rental chiller dry docked for winter. Old timer told me last time i found this problem on another system , yes sometimes u find this , should be ok, didn't find to many shavings , but there where some. Any Thoughts would be most appreciated.

    I am going to guess that it was rented out just recently and went off on high head or just got delivered to a site. Powered up and was tripped off on high head.

    No is part of my winter work getting hvac ready for up coming spring/summer season. Last May system 1 went off on High differential pressure, I tagged it for repair, unit did not go out after that. Now I am replacing cartridge filter and found this. I have found this before on another unit, last year and just put new filter in , I will be servicing that unit next week and am real curious to see what I find. Just wondering if I should be investigating an oil flow problem to prevent damage
    Thanks

    Yes I was thinking well sitting for 6 months no power, I guess it is possible oil just migrated out of housing , crank case heater does work.

    More the likely sitting with no power. Verify transducers and that 1/2 inch ball valve on oil line is not closed. The compressor block heater would have kept R-134 out of compressor so when temp changes happened thru out the day oil would stay.
    Rental chillers have a hard life , I would get on line before and then see what's going on.
