Recovered refrigerant must go into a DOT-approved refillable recovery cylinder, never a disposable one-trip cylinder, which is illegal and unsafe to refill. The cylinder must be within its hydrostatic test date and filled to no more than 80 percent. Proper cylinders prevent contamination and rupture.
