Can we use R-22 with POE oil or changing the comp. to minerial oil is better?

jwasir,

With Copeland compressors you can. POE is backward compatible with most refrigerants, with the exception of R12, and can be mixed with mineral oil.

Here is a link to Copelands AE bulletins.

Check out;
Section 17 #17-1248 and
Section 26, #93-11R16

Just bought a small Copeland semi hermetic today, its for a 22 system and it comes with POE.

You can't get them here with mineral oil any more.
