Introduction
The publication will give specific instructions for the installation of two air conditioner conversion arrangements.
- The following machines use the 192-1512 Air Conditioner Conversion Ar : 950G, 962G and IT62G.
- The following machines use the 192-5373 Air Conditioner Conversion Ar : 966G and 972G.
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. A 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 hardness. Do a leak test on all the hoses and all the lines. Refer to the Testing and Adjusting section of Service Manual, SENR5664, "Air Conditioning and Heating Systems with R-134A Refrigerant", "Refrigerant Leakage Test". Replace the hose if the hose has a leak or the outside becomes brittle. Replace the hose with a new hose that is sealed and free of contaminants.
The correct use of the wrenches is very important when the 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 when 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 the Service Manual, SENR5664, "Air Conditioning and Heating Systems with R-134A Refrigerant", "Refrigerant Recovery".
Install the protective plugs or the caps on all components and all hoses that are disconnected.
The O-ring 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 the time of installation. Do not use any kind of sealant on any of the air conditioner hose connections.

NOTICE |
---|
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide", for tools and supplies suitable to collect and contain fluids in Caterpillar machines. Dispose of all fluids according to local regulations and mandates. |
Personal injury can result from contact with refrigerant. Contact with refrigerant can cause frost bite. Keep face and hands away to help prevent injury. Protective goggles must always be worn when refrigerant lines are opened, even if the gauges indicate the system is empty of refrigerant. Always use precaution when a fitting is removed. Slowly loosen the fitting. If the system is still under pressure, release it slowly in a well ventilated area. Personal injury or death can result from inhaling refrigerant through a lit cigarette. Inhaling air conditioner refrigerant gas through a lit cigarette or other smoking method or inhaling fumes released from a flame contacting air conditioner refrigerant gas, can cause bodily harm or death. Do not smoke when servicing air conditioners or wherever refrigerant gas may be present. Use a certified recovery and recyling cart to properly remove the refrigerant from the air conditioning system. |
Note: Put identification marks on all hoses and on all wires for installation purposes. Plug the hoses. This will help to keep contaminants from entering the system.
