Important information about filling with refrigerant

NOTE:

Refrigerant must only be filled via the service valve (TXV system) on the high pressure (HP) side.

HINT: A specification decal in the engine compartment lists the refrigerant capacity of the air conditioning (A/C) system.

NOTE:

The most common cause of failed filling on the high pressure side 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.

NOTE:

When filling with refrigerant, compensate for the volume in the filling hoses before closing the filler valve.
