a.A disposable one-trip cylinder
b.A refillable DOT-approved recovery cylinder
c.An open bucket for liquid
d.Any container that fits the refrigerant
Giải thích
Recovered refrigerant, including from low-pressure chillers, must be stored in a refillable DOT-approved recovery cylinder, never a disposable one-trip cylinder. The cylinder must be within its five-year test date and filled to no more than 80 percent. Using improper containers is illegal and dangerous.
