Regarding POE/Mineral Oil compatibility, how do you know if the original manufacturer (1070's - 1980's) flowed Nitrogen (or other inert gas) during construction 45 years ago? If you assume the mfg.did not flow Nitrogen, then you've got Cupric (copper) Oxide on the inside of the original construction. Not a problem for mineral oil, but POE would strip the cupric oxide from [the inside] of a brazed joint that was joined without flowing Nitrogen. In that case, you've got the potential for acid. I would think a good suction filter should be added regardless of a burnout issue or not.
I have a Goodman R22 like 12 years old model GSC130421BA Copeland compressor. It still runs well but want to prepare for when it goes down so I bought a direct replacement for it but the replacement has POE in it. I was told that it’s directly compatible with mineral oil was kinda doubting that. They said if the system is R22 prior to 1978 you may want to drain out all the POE and put in mineral oil in the compressor but if it’s more modern the two oils will mix well? The procedure looks so simple to drain out that POE and refill with mineral oil. Is it true I can just leave the POE and not dump it out for mineral oil as long as the installer used nitrogen when they were brazing the lines that POE being also a detergent can actually sludge things up with the mineral oil? Also, should I equilibrate the insides in other words do a few drain and fills to make sure all the POE comes out because there’s always gonna be some left inside? The wasted mineral oil will be minimal.
Personally I would just drain the PPE oil out of the compressor. It is so quick and easy. The sticker on the side of the compressor will tell you how much POE oil there is in the compressor. I’d just lean it over and leave it draining until it has all come out. Doesn’t take long at all. I drained the oil into a measuring cup so I knew it all came out. Then I measured the right amount of mineral oil into the comp. That way the whole system is using mineral oil. Mineral and POE oil do not mix together no matter what age the unit is. That is my understanding anyway. There are videos on RUclips that show you what happens when they mix. If you do a few times, that is great but I don’t think it’s overly important. I just drained and filled once. As long as most of it is out is good enough in my opinion. This compressor has been running perfectly since. I’d go onto Copelands website to see if your compressor takes 3GS or 4GS mineral oil.
I had no idea there is a difference in mineral oil what’s the difference? Did you mean POE or PPE? I bought from johnstone’s supply in 2020 1 gallon of Nu-Calgon C-3s says it replaces 3GS. They never told me about 4GS at that time or if this one I have is compatible with compressor model ZR38K5EPFV800. There is 42oz of POE in this unit. On their website there is a table of recommended oil’s odd, it says POE for R22. Anyhow it list oils below and says 3GS but Nu-Calgon is not one of the choices. Dam hope what I have will work ok. I see Suniso 3GS, texaco capella WF-32, FUCHS Reniso KM32 and Copeland white oil.
@@imun1ty That was a typo, I meant POE. In regards to mineral oil, 4GS is thicker then 3GS. I’d just check the Copeland specs of the model compressor you have on google. Chances are it does in fact take 3GS.

@@vinnyinwallawalla1877 I actually bought the compressor two of them one 3 years ago and another a month ago. I would think they would have used nitrogen purge to braze. They capped the ends with plastic cap assuming they have it filled with nitrogen. I still don’t know what mineral oil to use 3GS or 4GS.
I copied this from an on-line search>>>>Can mineral oil be used with R-407C? R-407C is a zeotropic HFC refrigerant blend rated A1 by ASHRAE (lowest levels of toxicity and flammability), having zero ozone depletion potential. POE lubricants must be used with R-407C since its components are not miscible with the mineral oil or alkylbenzene lubricants found in most R-22 systems.
It’s applicable to any brand and any type of compressor. You need to match the oil of the compressor with the oil of the refrigerant. All you need to do is look what type of oil is used (which will be written on the label that is on the side of the compressor) and find out what oil is in the system currently.
You need to get that information from the manufacturer mate. There’s a few different factors that contribute to how long you need the capillary tube to be.

Can we charge oil from suction line ?
is it also applicable to danfoss compressor?
can i add a filter drier to the system that has no filter drider if yes where can I add it?
Yeah you can. You can put a filter drier in the liquid line. If the original compressor burnt out then you should put a burn out drier on also.
@@maracservices thanks you so much🙏
I have r407c compressor can remove Poe oil and refill mineral oil then use r22 please help us
Yep that’s right
Thanks

i mean danfoss scroll compressor?

Hi how can you adjust capillary tube in ac or r22 or r410 (when we don't have exact compressor for ac unite rotary scroll or another model)?
You need to get that information from the manufacturer mate. There’s a few different factors that contribute to how long you need the capillary tube to be.
@@maracservices thanks so much, do you have any information or book about it?
Why you add 3gs not 4gs
That’s what Copeland recommend for that model compressor.
Ok ok ok
