INSTALLATION
Any kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire air conditioning system. Kinks and sharp bends reduce the
flow of refrigerant in the system. A good rule for the flexible hose refrigerant lines is to keep the radius of all bends at least ten times the diameter of the
hose. In addition, the flexible hose refrigerant lines should be routed so they are at least 80 millimeters (3 inches) from the exhaust manifold.
1. Position the discharge line into the engine compartment.
2. Remove the tape or plugs from the compressor discharge port and the discharge line fitting.
3. Lubricate a new rubber O-ring seal with clean refrigerant oil and install it on the discharge line fitting.
4. Connect the discharge line fitting to the compressor discharge port on the top of the compressor.
5. Install the bolt that secures the discharge line fitting to the compressor. Tighten the bolt to 23 N.m (17 ft. lbs.).
6. Remove the tape or plugs from the condenser inlet port and the discharge line fitting.
