Dryer Cartridge, Removing And Installing, SHOWA/KEIHIN Condenser: Installing

WARNING: This page is about a different car, the 2023 Audi S3, 2023 Audi RS 3, 2023 Audi A3 Quattro, and 2023 Audi A3. However, it is still accessible from the selected car via links, so may be relevant.

Install in the reverse order of removal while noting the following:

Replace the plug, O-ring and dryer cartridge after every opening of the receiver/dryer. Refer to Parts Information.
Keep the dryer cartridge sealed in its air-tight packaging as long as possible. Open the package just before inserting the dryer cartridge in the condenser. The dryer cartridge absorbs moisture from the surrounding air in a very short time and becomes unusable.

-- Using the opening, inspect the receiver/dryer on the condenser for dirt and damage on the threaded- and sealing surfaces.

-- Coat the O-ring with refrigerant oil before installing. Refer to SEALS AND GASKETS .

-- Lightly coat the filter element -F- in the sealing surface area -J- with refrigerant oil before installing. Refer to SEALS AND GASKETS .
