1. Cautionary Information
1.
System Pressure Release
Before disconnecting any lines, always make sure that the refrigerant has
been removed from the A/C system by recovering it with the appropriate
equipment. When working on compressors, always be sure to relieve internal
pressure first. Internal compressor pressure can be relieved by removing the
oil plug (if necessary) or by removing shipping caps/pads from both ports.
2.
Recovery of Refrigerant
Never discharge refrigerant to the atmosphere. Always use approved
refrigerant recovery equipment.
3.
Handling of refrigerant
Always wear eye and hand protection when working on an A/C system or
compressor.
4.
Ventilation
Keep refrigerants and oils away from open flames. Refrigerant can produce
poisonous gasses in the presence of a flame. Work in a well ventilated area.
5.
Avoid use of Compressed Air
Do not introduce compressed air into an A/C system due to the danger of
contamination.
