Xenos is correct as to the issues with moisture in a system. Severe cases can result in orfices in TXV's freezing closed causing the valve to become inoperative. The more subtle problem is with foreign materials,copper and brass particles,etc. acting as a catalyst in the presence of moisture, refrigerant , oil and heat. The resulting chemical reaction can form acids which cause corrosion of system components and the sludging of oil.
All refrigerants are safe - All refrigerant are dangerous. The difference is YOU !!!

I have heard of the outlet of the metering device freezing up and acting like a defective valve. For my self I have always equated moisture to acid so I'm not quite sure how long you can have moisture before it turns to acid.
Xenos.
The best way to escape a problem is to solve it.
