INSTALLATION PROCEDURE

1. Before installing the O-ring, inspect the pipe/ hose for any damage.





2. Verify the O-ring is clean and free from defects. Place O-ring on pipe. Be sure it is seated properly (figure 1).





3. Lightly apply oil to the O-ring with refrigerant oil. Do not oil the threads or connecting hose seat (figure 2).






4. Align both fittings before threading on the nut (figure 3).





5. After threading on the nut, tighten it by hand as much as possible (figure 4).





6. Torque the nut to the proper specification, using a backup wrench to prevent damage (figure 5).











To further assist in A/C installation and repairs, a list of torque specifications for all hose and pipe connections has been compiled. The list only applies to A/C kits manufactured by Mazda North America. For the location of each of the fittings, refer to the "applied location" section of chart 1. The letters in this section correspond to locations shown in figures 6-12.
