Removal ("U" Series)

  1. Remove air cleaner and duct assembly. Discharge A/C system, using approved recovery/recycling equipment. Using a back-up wrench, loosen condenser outlet (liquid) line fitting at orifice tube. Disconnect liquid line. Remove and discard "O" rings. Using needle-nose pliers, remove orifice tube from liquid line.
  2. If difficulty is encountered during removal of a plugged or restricted orifice tube, remove as much residue as possible. Using a heat gun, carefully apply heat 1/4" from dimples on liquid line. DO NOT overheat line.
  3. If A/C pressure switch is located near orifice tube, remove switch to protect from heat. While heat is being applied, grip orifice tube using needle-nose pliers. Use a turning motion along with a push-pull motion to loosen and remove orifice tube.
