Hello all,
Just lately I seem to be coming across more and more units that have had r134a removed and replaced with gasses like 'care 30'.
Surely unless the electrics are sealed ( made spark proof) it can't be very safe, because all it takes is a leak to mix with air and it could cause a small explosion.
I haven't had any experience in handling flammable HFC's so could someone correct me if I'm wrong.

Thanks Neil
