Dryer Cartridge And Desiccant Bag, Replacing Without The Need For Cleaning Refrigerant Circuit
The dryer cartridge/desiccant bag are usually installed in the receiver/dryer depending on the design of the refrigerant circuit. Refer to Refrigerant Circuit (vehicle-specific Service Information).
- Pay attention to the general information for replacing components. Refer to GENERAL INFORMATION FOR REPLACING COMPONENTS .
Cleaning the refrigerant circuit means flushing with refrigerant R1234yf. Refer to REFRIGERANT CIRCUIT, CLEANING .
- For example, no escape of refrigerant and no ingress of moisture and dirt into the circuit.
- If it is determined at a gas analysis that contaminated refrigerant was in the circuit but there is no concern about the A/C system function. Refer to REFRIGERANT GAS ANALYSIS, PERFORMING .
-- Discharge the refrigerant circuit. Refer to WORKING WITH A/C SERVICE STATION .
-- Replace the dryer cartridge/desiccant bag (or reservoir/receiver/dryer). Refer to Refrigerant Circuit (vehicle-specific Service Information).
If the dryer cartridge/the desiccant bag is securely installed in a component (for example, in the receiver/dryer on the condenser) and cannot be replaced separately. Replace the receiver/dryer or condenser. Refer to Refrigerant Circuit (vehicle-specific Service Information).
-- Assemble, evacuate and fill the refrigerant circuit. Refer to WORKING WITH A/C SERVICE STATION .
