IMPORTANT INFORMATIONSAFE REFRIGERANT HANDLINGWhile these items will not cover every conceivable situation, they should serve as a useful guide.WARNINGRefrigerants are heavier than air. They can "push out"the oxygen in your lungs or in any enclosed space.Toavoid possible difficulty in breathing or death: Never purge refrigerant into an enclosed room orspace. By law, all refrigerants must be reclaimed. If an indoor leak is suspected, thoroughly ventilatethe area before beginning work. Liquid refrigerant can be very cold. To avoid possiblefrostbite or blindness, avoid contact with refrigerantand wear gloves and goggles. If liquid refrigerantdoes contact your skin or eyes, seek medical helpimmediately. Always follow EPA regulations. Never burn refrigerant, as poisonous gas will be produced.WARNINGTo avoid possible injury, explosion or death, practicesafe handling of refrigerants.WARNINGHIGH VOLTAGE!Disconnect ALL power before servicing or installingthis unit. Multiple power sources may be present.Failure to do so may cause property damage, personalinjury or death.WARNINGTo avoid possible explosion: Never apply flame or steam to a refrigerant cylinder.If you must heat a cylinder for faster charging,partially immerse it in warm water. Never fill a cylinder more than 80% full of liquidrefrigerant. Never add anything other than R-22 to an R-22 cylinderor R-410A to an R-410A cylinder. The service equipmentused must be listed or certified for the type ofrefrigerant used. Store cylinders in a cool, dry place.
