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.
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).
