Volkswagen Golf Service & Repair Manual: Safety precautions when handling refrigerants
| Risk of freezing injury caused by refrigerant |
| When working on the air conditioning system, there is a risk of highly pressurised refrigerant escaping from the system. There is a risk of injury to the skin and parts of the body due to freezing. |
| – | Always wear safety gloves. |
| – | Always wear safety goggles. |
| – | Extract refrigerant, and open the refrigerant circuit immediately afterwards. |
| – | If more than 10 minutes passed since the refrigerant has been extracted, do not open the refrigerant circuit prior to extracting refrigerant anew. Due to re-evaporation, pressure will be built up in the refrigerant circuit. |
| Risk of damage to refrigerant lines |
| There is a risk of damage to the refrigerant lines due to rupture of the inner foil. |
| – | Never bend refrigerant lines to a radius less then 100 mm (r < 100 mm). |
