Use care to prevent refrigerant from touching skin or eyes. Liquid refrigerant, when exposed to air,
quickly evaporates and will freeze skin or eye tissues. 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
compressed air. Combustible mixtures of air and R-134A may form, resulting in a fire or explosion,
which could cause personnel injury or death.
Recover system refrigerant (refer to b. Recovery).
Disconnect both ends of line or component to be purged.
Install caps or plugs tightly on system lines or components at disconnect points.
Charge or pressurize R-134A refrigerant (1) as recommended by manufacturer.
Connect recovery/recycling station flushing supply line (2) to outlet hose (3) side of system to reverse flow
