Figure 5-3. Discharging Refrigerant
Death or serious injury may result if personnel fail to observe safety precautions. Use great
care to avoid contact with liquid refrigerant or refrigerant gas being discharged from any
container under pressure. Sudden and irreversible tissue damage can result from freezing.
Wear thermal protective gloves and a face protector or goggles in any situation where
skin-eye contact is possible.
Prevent contact of refrigerant gas with flame or hot surfaces. Heat causes refrigerant to
break down and form carbonyl chloride (phosgene), a highly poisonous and corrosive gas.
d. Connect the charging manifold hoses to the manifold and air conditioner service valves.
e. Attach a hose assembly to the center connection of the manifold.
Discharge refrigerant in an open area and not around an open flame.
