[QUOTE=k-fridge;10425412] I think we'll see it go away in a few years.
Honeywell considers it long term on there Guide to Alternative Refrigerants.
Along with R404a,R507,R422a,R422d,&R407c.
I personally think it should be banned in small cap tube reach-in's.
On the flipside those Artic Air Freezers can get down to -30*
Also many domestics refrigerators run the low side in vaccum.
The serial number is JA0995. I think it means it was made in 95. The newer models use a TXV.
