Volkswagen Golf Service & Repair Manual: Welding and soldering on refrigeration systems
| Before welding and brazing on vehicles (in the vicinity of
the air conditioning system components), extract the refrigerant
and then purge the system by blowing through with compressed air
and using nitrogen. |
| The products of decomposition of refrigerants under heat are
not only poisonous but are strongly corrosive, so that pipework
and system parts could be attacked. This refers primarily to
hydrogen fluoride. |

mentioned above are already present. Breathing in these
substances must be avoided under all circumstances, or the
bronchial tubes, lungs and other organs could be injured. |
