Hello,

We have a reciprocating semi hermetic compressor with mineral oil and i want to change oil to POE because i want to use this compressor in a cooling unit running with R407C...

First of all i would like to learn how can i removed the mineral oil from the compressor and before add the POE lubricant i have to vacuum the compressor or not? If these lubricants are mixed each other a little, is there any problem in running the system?

I hope i explain my questions enough...


Best Regards
