General Safety Instructions:
W A R N I N G
l
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.
l
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.
