Dryer Cartridge, Removing And Installing, DENSO Condenser: Installing

Install in reverse order of removal and note the following:

NOTE:

Replace the plug, O-ring and dryer cartridge after every opening of the receiver/dryer. Refer to Parts Information.

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

NOTE:

Keep the dryer cartridge sealed in its air-tight package as long as possible. Open the package just before installing the dryer cartridge into the condenser. The dryer cartridge absorbs moisture from the surrounding air in a very short time and becomes unusable.

Coat the O-ring for the plug with refrigerant oil before installing. Refer to REFRIGERANT CIRCUIT SEALS .

-- Insert the filter element -E- into the condenser receiver/dryer on the proper side.
