EPA 608 Refrigerant Recovery, Recycling & Reclamation

Question 1

What is the primary difference between refrigerant recycling and reclamation?

Accepted Answer

Recycling is done on-site and reused by the same owner; reclamation is done at an EPA-certified facility to meet ARI 700 standards

Answer

Recycling removes moisture only; reclamation removes all contaminants including oil

Answer

Recycling requires EPA certification; reclamation does not

Answer

Recycling is permitted for CFC refrigerants only; reclamation is for HFCs

Question 2

To remove refrigerant from a system and store it without releasing it into the atmosphere

Answer

To increase refrigeration system efficiency before repairs

Answer

To test the refrigerant purity before recharging

Answer

To recycle the refrigerant for immediate reuse in a different system

Accepted Answer

System-dependent (passive) recovery unit

Answer

Self-contained recovery unit

Answer

Push-pull recovery unit

Answer

Vapor-recovery only unit

Question 7

Under EPA 608 regulations, when must a certified technician recover refrigerant?

Accepted Answer
