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. 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 personnel injury or death.
