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 recycling cart to properly remove the refrigerant from the air conditioning system.

Note: Put identification marks on all hoses, and on all harness assemblies for installation purposes. Plug all hoses. This helps to prevent fluid loss, and this helps to keep contaminants from entering the system.

1. Recover the air conditioning system. Refer to Service Manual, SENR5664, "Air Conditioning and Heating Systems with R-134A Refrigerant"and Special Publication, NEDG5065, "Air Conditioning Tools". The publications will provide the proper procedure, equipment and tools in order to evacuate the air conditioning system in any Caterpillar machine.
