| Working on refrigerant circuit |
| Work on the refrigerant circuit is only to be performed in well ventilated areas. Care should be taken to ensure that there are no inspection pits, shafts or cellar entrances within a radius of 5 metres. Extraction systems are to be switched on. |
| The refrigerant which emerges is not only colourless and odourless, but also heavier than air and therefore displaces oxygen. Should refrigerant gas escape despite compliance with all safety precautions, there will be a previously impercepible risk of asphyxiation in poorly ventilated areas and inspection pits. |
Note | The mixture of gas and air which forms when refrigerant gas escapes is not to be inhaled. It must be extracted using suitable extraction systems (workshop extractor). |
| Welding, brazing and soldering operations are not to be performed on air conditioner components when filled. This also applies to vehicle welding and soldering work if there is a danger of air conditioner components becoming hot. |
| Heat generation causes considerable pressure to build up in the system and this could lead to rupturing of the system. |
Note | Damaged or leaking air conditioner components are not to be repaired by welding or soldering, but should be replaced. |
| When servicing the air conditioner, all open components and line connections are to be immediately re-sealed. |
| Moisture will ingress into the air conditioner components if they are left open for a lengthy period. If this is the case, air conditioners cannot be re-filled without having to replace parts of the system. |
