9. Refrigerant hose routing.Note:Lubricate "O” rings with refrigeration oil before installing them on all refrigerant hose fittings.Provide sufficient clearance around sharp angles and edges to prevent damage to refrigeranthose assemblies.Caution: Do not leave hoses unsupported! The service life of the air conditioner unit, condenser andhose assemblies may be greatly reduced if hoses are not properly secured. Hose clamps andtie wraps are provided in the general installation kit to secure hose assemblies.a. Attach the #8 and #10 refrigerant hose assemblies to the compressor and route both hoses downbetween the frame rail and radiator. See Figures 5 and 6. Then route the 90° bent end, of the #10refrigerant hose assembly up through the boot into the tool compartment. Attach the #8 hose to thecondenser. See Figures 4 and 5.b. Attach the (30”) #6 refrigerant hose assembly to the #6 refrigerant hose fitting on the condenser, thenroute and attach it to the "in-port" on the receiver drier. See Figure 4.Note: Use a tie wrap to secure the #6 hose assembly for the front frame support.c. Attach (56'" #6 refrigerant hose assembly to the "out-port" of the receiver drier, then route it upthrough the boot and into the tool compartment. See Figures 4 and 6.d. Attach trinary wire harness to trinary switch on receiver/drier assembly. Route black wire from thetrinary to the compressor clutch. Route trinary and condenser wires up through boot into toolcompartment. Provide sufficient clearance around sharp edges to prevent damage to insulation.Secure wires with tie wraps provided in kit.e.
