Attention! Do not open the refrigerant circuit in the air conditioner. The refrigerant contains substances that, in contact with the skin, can cause frostbite.
1. Clean the level gauge (arrow) on the liquid container.
2. Remove the plug from the temperature sensor (coolant / air conditioning) (B10/8). Shunt the connections with the auxiliary wire.
3. Start the engine and leave it to idle.
4. Turn on the air conditioner and set it to "Defrosting" or "Air drying".
5. Remove the jumper on the plug connector while observing through the peephole on the refrigerant tank. Shortly after switching on the magnetic coupling, the refrigerant must rise and then flow without bubbles. In this case, the refrigerant may no longer be visible.
6. Slide the plug connector onto the temperature sensor.
Attention! At higher ambient temperatures (over +35°С) even with a normal amount of filling refrigerant, foam and some bubbles may appear. In the event of a refrigerant leak or a suspected system leak, the correct amount of refrigerant to fill can only be determined by completely draining and refilling the system (work in a car shop).
