Recovery & RecyclingQuestion 223 of 240

To avoid cross-contamination when switching from recovering one refrigerant to another, a technician should:

a.Use one cylinder per refrigerant
b.Use the same cylinder for both
c.Mix them in a single drum
d.Skip identifying the second refrigerant

Explanation

Between refrigerants, evacuate the recovery machine and hoses and use a separate, dedicated cylinder for each refrigerant to prevent cross-contamination. Reusing a cylinder or skipping identification can create a mixed batch that cannot be reclaimed. Clean separation preserves the refrigerant's value.
