Refrigerant, Filling






Refrigerant, filling

Note! Some variation in the illustrations may occur, but the essential information is always correct.


Warning! Follow the safety instructions for work on the air conditioning system.

Note! First read the instructions covering slow and fast leaks.





Only fill with refrigerant on the high pressure side (HP) (1) service valve (TXV system).
A specification decal in the engine compartment specifies the refrigerant capacity of the air conditioning system.


Note! The most common causes of failed filling of refrigerant is incorrect vacuum pumping or because the pressure in the filling unit is not high enough, or a combination of these two.

Note! The filling unit should preferably have a heating unit for refrigerant. This is so that the pressure in the filling unit is higher than in the system that is to be filled.

Compensate for the volume of refrigerant in the filling hoses before closing the filler valve.
