Dear All,

I have two issues where I don't really know what would be the proper solution.

1. After about 10 years one of the compressors in a chiller went wrong and has been replaced. For this reason the refrigerant has been removed from the system by a professional and has been refilled together with a new compressor unit. This means the refrigerant has been added in that machine but not because of leakage problems and the "old" refrgirenat has been removed professionally so nothing is lost.

2. In a chiller one of the refrigerant circuits works with R422D refrigerant which is retrofit replacement for R22 and I beleive with more favourable environmental effects. However I cannot choose this type on the form.
