Removal ("G", "L" & "M" Series)

  1. Discharge A/C system, using approved recovery/recycling equipment. Using a back-up wrench, loosen evaporator inlet (liquid) line fitting at evaporator. Disconnect inlet line. Remove and discard "O" ring(s). Using Orifice Tube Remover/Installer (J-26549-E), 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 orifice tube remover/installer. Use a turning motion along with a push-pull motion to loosen and remove orifice tube.
