This publication will give instructions for the field installation of an air conditioner assembly.
The 12H, 140H, and 160H use the 192-1511 Air Conditioner Gp .
The 120H and 135H use the 192-5372 Air Conditioner Gp .General Information
All refrigerant lines must be free of sharp bends. Also, do not use a refrigerant line that is kinked. Sharp bends will cause a restriction in the refrigerant flow. Restriction in the lines will reduce the performance and the efficiency of the system.The radius of bends in the flexible hose must never be less than 10 times the outside diameter of the hose.Do not allow the flexible hoses to come within the 63.5 mm (2.5 inch) of the exhaust manifold.The hoses need to be inspected yearly for leaks and for hardness. Do a leak test on all the hoses and all the lines. Refer to the Service Manual, SENR5664, "Refrigerant Leakage - Test" section in Testing and Adjusting. Replace the hose if the hose leaks. Replace the hose if the hose is brittle. Replace hoses with a new hose that is sealed and free of contaminants.The correct use of wrenches is very important when connections are made. The type of wrench is also important. Use only the wrenches that are made for use with the tube type fittings. When a hose or a metal line is connected or a hose or a metal line is disconnected, use a wrench on the fitting and on the nut. Also use a wrench on the hose connection.When the components and the refrigerant lines are disconnected, refer to the Testing and Adjusting section of Service Manual, SENR5664, "Refrigerant Recovery".Install protective plugs or caps on all components and all hoses that are disconnected.The O-rings and the seals must be in good condition. Small cuts, scratches or particles of dirt will cause a leak in the system. Put new refrigerant oil on all new O-ring seals at time of installation. Do not use any kind of sealant on any of the air conditioner hose connections.Standard Torques for Air Conditioner Fittings
