Abrupt refrigerant loss due to a large leak, hose rupture, collision, or pressure relief valve opening. Conditions that allow the refrigerant to seep or bleed off over time do not cause this oil loss. Upon replacement of a component that caused a large refrigerant loss, also add the required amount of oil for the particular component. If more than the specified amount of PAG oil was drained from a component, add the equal amount of oil drained.
