Important information about filling with refrigerant

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Volvo S80, 2005 Volvo S80, 2004 Volvo S80, 2003 Volvo S80, and 2002 Volvo S80. However, it is still accessible from the selected car via links, so may be relevant.

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.
