AIR CONDITIONER COMPRESSOR REPLACEMENT (CONT)
WARNING
•
Use care to prevent refrigerant from touching your skin or eyes, because
liquid refrigerant, when exposed to air, quickly evaporates and will freeze skin
or eye tissue. Serious injury or blindness could result if you come in contact
with liquid refrigerant.
•
Refrigerant R-134a air conditioning systems should not be pressure tested or
leak tested with compressed air. Combustible mixtures of air and R-134a may
form, resulting in a fire or explosion which could cause personal injury.
