Desiccant in the Air Receiver/Dryer
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.
The dryer must be replaced when repairing a major leak or replacing a component, or if moisture is suspected to have entered the system. The unit need not be replaced more often than on every third occasion if only minor work is carried out under favorable conditions. Favorable conditions are defined, for example, as a slow leak (over 24 hours) which is repaired immediately. When installing new components in a one-year-old car the receiver need not be replaced.
CAUTION:
To avoid corrosion, the system must be filled immediately after installation.
If the car has been left standing for more than 24 hours without refrigerant in the system, the system must be flushed twice with approximately 200 grams of refrigerant. Between the two flushing operations, pump the system completely empty for at least 10 minutes.
NOTE:
Return used refrigerant to the supplier who is responsible for safe disposal of environmentally harmful substances.
