Hi All,

Was chatting to an old service guy a while back who told me, he sometimes determines a system refrigerant and oil by smell he said sometimes you can get a sweet smell which could be caused from a grounded comp which contaminated the system.

It got me thinking as I was working on a Daikin VRV R407C and when I was recovering the refriegent I could smell a strong odour. Is this due to the make up of R407c or possible contamination?

Feed back much appreciated.
