It is impossible to open a circulating contour of coolant in the conditioner. Coolant contains substances which in contact with skin can lead to a frostbite.

1. Clear the index of the level (shooter) on a tank with liquid.
2. Remove the shtekkerny socket from the thermal sensor (the cooling means / conditioning) (B10/8). Zashuntiruyte of connection by an auxiliary wire.
3. Start the engine and leave it to idle.
4. Turn on the conditioner and install it in situation "Defrosting" or "Drying by Air".
5. Remove a crossing point on the shtekerny socket and at the same time observe through a peephole on a tank with coolant. Quickly after turning on of the electromagnetic connecting coupling coolant has to rise and then proceed without bubbles. In this case coolant can be we do not see any more.
6. Pull the shtekkerny socket over the thermal sensor.


At more high temperatures of the environment (over +35 °C) even at normal amount of the filling coolant foam and a few bubbles can appear. At leak of coolant or estimated leakage of system the correct amount of the filling coolant can be defined only by full depletion and new filling of system (work in auto repair shop).
