Volkswagen Polo Service & Repair Manual: Water Content

Only very small amounts of water are soluble in liquid refrigerant. On the other hand, refrigerant vapor and water vapor mix in any ratio.
Only a small drop of water may get into the refrigerant circuit. The dryer, dryer bag or dryer cartridge contained in the reservoir can absorb approximately 7 grams of water. They are then saturated and cannot absorb any more water. If water is still present in the refrigerant circuit, it flows up to the expansion valve nozzle or restrictor and becomes ice.
The air conditioning system stops cooling.
Water destroys the air conditioner as it combines with other impurities at high pressures and temperatures to form acids.
   

Combustibility

Refrigerant is non-flammable. It actually has a fire resistant or fire extinguishing effect. Refrigerant decomposes when exposed to flames or red-hot surfaces. UV light (occurring for example during electric welding) also causes refrigerant decomposition. The resultant decomposition products are toxic and are not to be inhaled. However, irritation of the mucous membranes provides an adequate and timely warning.
