- What is the primary difference between recovery and recycling of refrigerants?
- Recovery removes refrigerant from equipment and stores it. Recycling cleans and reuses it on-site without laboratory testing.
- What does reclamation of refrigerant mean?
- Restoration of refrigerant to original purity specifications by a certified EPA facility using equipment and procedures meeting ARI standards.
- Which EPA 608 certification level allows technicians to service all types of refrigeration equipment?
- Universal certification.
- What is Type I certification valid for?
- Servicing of small appliances containing 5 pounds or less of refrigerant.
- What is Type II certification valid for?
- Servicing high-pressure (positive displacement) refrigeration systems such as air conditioning.
- What is Type III certification valid for?
- Servicing low-pressure (centrifugal) refrigeration systems such as chillers.
- What is the maximum amount of refrigerant loss allowed during recovery before it must be reclaimed?
- Refrigerant that cannot be recovered must be sent for reclamation; no specific loss limit is acceptable without disposal.
- What standard do EPA-certified recovery/recycling machines must meet?
- ARI 740 standard.
- What type of oil removal is required during refrigerant recovery?
- Oil must be separated from refrigerant using recovery equipment and disposed of properly or recycled separately.
- What must recovery cylinders be equipped with to prevent overfilling?
- A safety relief valve.
- What is the maximum fill level allowed in a recovery cylinder by weight?
- 80 percent of the cylinder's water capacity by weight.
- What color are EPA-approved refrigerant recovery cylinders typically marked?
- Yellow (for recovered refrigerant) and other colors depending on contents, meeting Department of Transportation specifications.
- What must be on the label of a recovery cylinder containing used refrigerant?
- The type of refrigerant, the amount of oil in it, the date of recovery, and the name of the technician who recovered it.
- How must recovered refrigerant be transported?
- In DOT-approved cylinders that are properly labeled and securely fastened in the vehicle.
- What is required before using a recovery/recycling machine on a different refrigerant type?
- The machine must be thoroughly purged of the previous refrigerant to prevent contamination.
