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. |
- Recover the refrigerant. Refer to Service Manual, SENR5664, "Air Conditioning and Heating Systems with R-134a Refrigerant" for the correct procedure. Refer to Special Publication, NEDG5065, "Air Conditioning Tools" for the correct tools.
- Remove the Belt. Refer to Operation and Maintenance Manual, "Belts Inspect/Replace" to remove and install belt.

Personal injury or death can result when charging an air conditioning system with a liquid. The compressor will pump the refrigerant back into the charging cylinder with the possibility of rupturing (exploding) the cylinder. Do not operate the engine when charging with a liquid. Never charge liquid or gas through the discharge (high side of the system) with the engine running. Keep all other personnel either away from the machine or where they can be seen when working on the air conditioning system. |
- Install refrigerant compressor (4) in the reverse order of removal.
