WARNING

Use care to prevent refrigerant from touching your skin or eyes. Liquid refrigerant, when exposed to

air, quickly evaporates and will freeze skin or eye tissue. Use protective gloves and goggles. Serious

injury or blindness may result if you come in contact with liquid refrigerant.

Refrigerant R-134a air conditioning systems should not be pressure tested or leak tested with com-

pressed air. Combustible mixtures of air and R-134a may form, resulting in a fire or explosion, which

could cause injury or death to personnel.

DO NOT work in an area where refrigerant may contact an open flame or burning material such as a

cigarette. When refrigerant contacts extreme heat, refrigerant breaks down into poisonous phosgene

gas which, if breathed, causes severe respiratory irritation. DO NOT breathe fumes from an open

flame leak detector.

NOTE

Refrigerant capacity is 4-6 lb (1.8-2.7 kg).
