- DO NOT HANDLE REFRIGERANT IN AN ENCLOSED AREA OR NEAR AN OPEN FLAME
- ALWAYS WEAR PROTECTIVE GLASSES (Scheme 240): Precaution For Protective Glass
- AVOID SKIN OR EYE CONTACT WITH LIQUID REFRIGERANT If liquid refrigerant comes in contact with your eyes or skin: Wash the area with a lot of cold water. CAUTION: Do not rub your eyes or skin. Apply clean petroleum jelly to the skin. Go immediately to a hospital or see a physician for professional treatment. (Scheme 241): Precaution For Avoid Skin Or Eye Contact With Liquid Refrigerant
- NEVER HEAT CONTAINER OR EXPOSE IT TO OPEN FLAME
- DO NOT DROP OR STRIKE CONTAINER OF REFRIGERANT
- DO NOT OPERATE COMPRESSOR WITHOUT ENOUGH REFRIGERANT IN REFRIGERANT SYSTEM If there is not enough refrigerant in the refrigerant system, oil lubrication will be insufficient and the compressor may burn out. Necessary care should be taken to avoid this.
- DO NOT OPEN HIGH PRESSURE MANIFOLD VALVE WHILE COMPRESSOR IS OPERATING Open and close only the low pressure valve. If the high pressure valve is opened, refrigerant flows in the reverse direction and causes the charging cylinder to rupture. (Scheme 242): Identifying Correct And Incorrect Pressure Value
- BE CAREFUL NOT TO OVERCHARGE SYSTEM WITH REFRIGERANT Overcharged refrigerant will cause problems such as insufficient cooling, poor fuel economy, engine overheating, etc.
- DO NOT OPERATE ENGINE AND COMPRESSOR WITHOUT REFRIGERANT IN REFRIGERANT SYSTEM NOTE: This may damage the inside of the compressor because the compressor parts always move regardless of whether the A/C system is on or off.
