b.Recycle it through an oil separator and filter-driers
c.Vent and replace it
d.Reclaim it in a lab
Explanation
Recycling equipment with an oil separator and filter-driers reduces oil, moisture, and acidity so recovered refrigerant can be reused on-site with the same owner. Reclamation to AHRI 700 requires a certified reclaimer and is needed for resale. Venting is never allowed.
