Desiccant Bag/Dryer Cartridge, Removing And Installing: Installing

Install in reverse order of removal

• Check the receiver/dryer -Item 7-  OVERVIEW - CONDENSER, if there is contamination, clean the refrigerant circuit or replace the condenser, if necessary. Refer to A/C System, General Information or REFRIGERANT CIRCUIT, CLEANING .
• Check the receiver/dryer and the threads on the condenser via the opening for damage. Refer to -item 6-  OVERVIEW - CONDENSEROVERVIEW - CONDENSER .
• Replace the plug -A- and then both O-ring seals (included in the delivery of the dryer. Refer to OVERVIEW - CONDENSER  and Parts Information).
• Coat the O-ring seals lightly with refrigerant oil prior to installation. Refer to SEALS AND GASKETS .
• Check the O-ring seals for proper seating in grooves of the respective components.
• Keep the desiccant bag sealed in its air-tight package as long as possible. Open the package just before installing the dryer cartridge in the receiver/dryer of the condenser. After opening the dryer cartridge absorbs moisture from the surrounding air in a very short time and becomes unusable. Refer to OVERVIEW - CONDENSER .

-- Remove the desiccant bag from its package and insert in the receiver/dryer. Refer to OVERVIEW - CONDENSER .

-- Install the plug -A- with the O-ring. Refer to OVERVIEW - CONDENSER .

-- Evacuate and charge the refrigerant circuit. Refer to Refrigerant Circuit or Working with A/C Service Station .

Vehicles with a High-Voltage System

-- Initiate the basic setting of the A/C system through the Thermal Management Control Module -J1024- and activate the power-controlled valves using one of the routines stored there. "Charge/flush the refrigerant circuit stop routine" using the Vehicle Diagnostic Tester.

Continuation for All Vehicles

-- Start the A/C system after charging the refrigerant circuit. Refer to A/C SYSTEM, STARTING AFTER CHARGING REFRIGERANT CIRCUIT .
