5 Refrigerant Recovery and Practical Review Free Online FlashCards

What does refrigerant recovery mean?

Recovering removes refrigerant from an appliance and stores it in an external container; it does not require cleaning or testing.

What is generally required before used refrigerant is sold to a new owner?

An EPA-certified reclaimer must reclaim used refrigerant before it is generally sold to a new owner.

How should recovery equipment be selected?

Use recovery equipment certified for the applicable appliance and refrigerant. Certification requirements can vary with appliance type, refrigerant, and manufacture date.

What is a key rule when identifying refrigerant before recovery?

Identify the refrigerant and its hazards first. Never mix refrigerants or put an unknown refrigerant into a cylinder containing a known refrigerant.

What determines the required recovery evacuation level?

Never vent refrigerant. Recover to the evacuation level required for the appliance and applicable rules; one target does not apply to every appliance.

How should a technician monitor a recovery cylinder while filling it?

Weigh the cylinder before and during recovery, and stop at its applicable maximum fill weight. Never rely on pressure or appearance alone.

How should a cylinder with unknown or possibly mixed refrigerant be handled?

Keep uncertain or potentially mixed refrigerant separate, label it clearly, and use an appropriate recovery and disposition process.

What should you do if a warm recovery cylinder has high pressure?

Do not release refrigerant to reduce pressure. Keep the cylinder away from heat and follow safe handling procedures; if unsafe, stop work and follow the site emergency procedure.

Which requirements generally govern recovery from motor vehicle air conditioners?

Motor vehicle air conditioners are generally handled under Section 609 requirements, not the ordinary stationary-equipment workflow.

How does refrigerant recycling differ from reclamation?

Recycling cleans recovered refrigerant, typically through oil separation and filtration, but does not verify purity to reclamation standards.

What makes refrigerant reclamation distinct?

Reclamation reprocesses refrigerant to applicable purity specifications and verifies its quality using the prescribed analytical method.

When may recycled stationary-equipment refrigerant be reused without reclamation?

Under Section 608, recycled refrigerant from stationary equipment may be reused in equipment owned by the same person, as permitted by the rules.
