Safety Precautions




Always wear eye protection
Be careful not to get liquid refrigerant in your eyes or on your skin. If liquid refrigerant gets in your eyes or on your skin, wash the area with lots of cool water, apply clean petroleum jelly to the skin and go immediately to a physician or hospital for medical treatment.

Do not rub your eyes or skin.

Never heat container or expose it to naked flame
Be careful not to drop container and not to apply physical shocks to it
Never operate the compressor without enough refrigerant in refrigerant system. If there is not enough refrigerant in the refrigerant system oil lubrication will be insufficient and compressor burnout may occur, so take care to avoid this, necessary care should be taken.
Do not open high pressure manifold valve while compressor is operating. If the high pressure valves opened, refrigerant flows in the reverse direction and could cause the charging cylinder to rupture, so open and close the only low pressure valve.
Be careful not to overcharge system with refrigerant. If refrigerant is overcharged, it causes problems such as insufficient cooling, poor fuel economy, engine overheating etc.
Remove refrigerant (R-134a) from the A/C system, using certified service equipment meeting requirements of SAE J2210 R-134a recycling equipment If accidental system discharge occurs, ventilate work area before resuming service. Additional health and safety information may be obtained from refrigerant and lubricant manufacturers.
