407C is a funny gas, they stopped using it in vrv's because of
the glide. 407C has about 7K glide and in some vrv's the
refrigerant fractures (fractionisation) and the refrigerant stops
working properly.

Another funny thing it does is it changes to 410A

R407C is made from R32, R125 & R134a and R410A is
made from R32 and R125 so because the 134a leaks
out first 407 turns into 410A.
