| Working on refrigerant circuit |
| Work on the refrigerant circuit is only to be carried out in well ventilated areas where there are no inspection pits, shafts or cellar entrances within a radius of 5 metres. Extraction systems are to be switched on. |
| The refrigerant emerging is not only colourless and odourless, but also heavier than air and thus displaces oxygen. Should refrigerant gas nevertheless escape, this can result in an imperceptible danger of asphyxiation in poorly ventilated areas and inspection pits. |
Note | The mixture of gas and air which forms when refrigerant gas escapes must not be inhaled. Use is to be made of suitable workshop extractors. |
| Welding, brazing and soldering are not permitted on sections of the air conditioner when filled. This also applies to vehicle welding and soldering work if there is a danger of air conditioner components becoming warm. |
| Exposure to heat creates considerable pressure in the system which could cause it to burst. |
Note | Damaged or leaking parts of the air conditioner are never to be repaired by welding or soldering them. They are always to be replaced. |
| When servicing the air conditioner, all open components and pipe connections are to be immediately re-sealed. |
| Moisture will ingress into 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. |
