1. Discharge A/C system using approved refrigerant recycling equipment, and disconnect the condenser-to-evaporator discharge line. Remove O-rings (if necessary).
2. Determine the suitable orifice tube removal tool for your application. If the discharge line includes a nut at the fitting go to step 7.
Discharge line without nut:
3. Assemble the tool without the adjusting nut on to the body. Install Adapter. (Fig v) Then insert the adapter into the discharge line. (Fig w)
4. Engage adapter with end of the orifice tube. Turn handle until tangs engage. Pull back on tool and remove orifice tube form the discharge line. (Fig x & y)
5. If orifice tubes break during removal. (Fig Ya) assemble the tool body with broken orifice tube extractor adapter. (Fig z)
6. Insert adapter end into discharge line Thread broken orifice tube until it is seated firmly. Pull back on tool and remove broken orifice tube from the discharge line. (Fig za)
Discharge line with nut at fitting:
7. Assemble the tool with adjuster nut with internal thread facing the adapter end, and insert the end into the discharge line.
8. Engage adapter with the end of the orifice tube. Rotate until fully engaged. Thread the adjuster nut onto fitting.
9. While holding handle of the tool stationary, tighten the adjuster nut to slowly remove orifice tube. Once orifice tube is free from the line, turn the adjuster nut off and pull tool
and orifice tube from discharge line.
10. If orifice tube breaks during removal (Fig x) assemble the tool body with broken orifice tube extractor adapter. (Fig z) and follow procedure in step 9.
