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.
REMOVAL
CAUTION
Water and dirt can damage refrigerant system. Five minutes of not being capped is the limit for any hose or
component. DO NOT blow shop air through refrigerant hoses. Shop air is wet (humid).
NOTE
DO NOT disconnect or connect refrigerant fittings using only one wrench. Hold one fitting in place using a
wrench and turn other fitting with a second wrench.
