| Air conditioning service station -VAS 6007A- (and other or latest available service stations) |
Caution | t
| It is recommended that a rinsing bottle be kept ready for irrigating the eyes. |
| t
| Should liquid refrigerant get into the eyes, thoroughly rinse the eyes with water for about 15 minutes. Then administer eye drops and visit a doctor immediately even if the eyes do not hurt. |
| t
| The doctor must be informed that the frostbite has been caused by refrigerant R134a. If, in spite of these safety measures, refrigerant comes into contact with other body parts, these areas must also be immediately irrigated with cold water for at least 15 minutes. |
| t
| Work on the air conditioning system refrigerant circuit in well ventilated rooms only. Switch on the available workshop fume extraction equipment. |
| t
| Refrigerant must not be stored in low-lying rooms (e.g. cellars) or their stairways or window shafts. |
|
| l
| Do not weld, braze or soft-solder any parts of the charged air conditioning system. This also applies to welding and soldering work on the vehicle when the danger exists that parts of the air conditioning system may heat up. During painting operations, temperatures of objects in the drying oven or in its pre-heating zone must not exceed 80° C. |
| Heating causes great excess pressure to develop in the system, which can cause the pressure release valve of the system to open. |
| –
| Use the A/C service station to evacuate the refrigerant circuit. |
Note! | Damaged or leaky parts of the air conditioning system may not be repaired by welding or soldering, they must always be replaced with new parts. |
| Refrigerant containers (e.g. charging cylinders of A/C service station) must never be subjected to excessive heat or exposed to direct sunlight. |
| –
| Never charge a container completely with liquid refrigerant. Without sufficient expansion space (gas cushion), the container will burst should the temperature rise, with devastating consequences → Chapter. |
| Under no circumstances may refrigerant be charged into systems or vessels containing air. |
| –
| Evacuate systems and containers before charging with refrigerant. |
