Recovery, Recycling, and Reclaiming Flashcards

Only an EPA-certified reclaimer may sell reclaimed refrigerant to a new owner; the reclaimed product must meet:

Answer: AHRI Standard 700 (ARI-700) purity

Reclaimed refrigerant sold to a new owner must meet AHRI/ARI Standard 700 purity specifications.

Refrigerant recovered from a contaminated or burned-out compressor system should be:

Answer: Recovered into a separate cylinder and sent for reclamation or destruction

Heavily contaminated refrigerant must be kept separate and sent for reclamation or destruction, never reused as-is.

When shipping a recovery cylinder of refrigerant, it must be labeled and transported in accordance with:

Answer: DOT hazardous materials regulations

Recovery cylinders are shipped under DOT hazardous materials regulations with proper labeling.

Before its first use, a new recovery cylinder should be:

Answer: Evacuated to remove air and non-condensables before adding refrigerant

A new or empty recovery cylinder should be evacuated to remove air and moisture before recovering refrigerant into it.

Air and other non-condensables in a recovery cylinder are a problem because they:

Answer: Raise cylinder pressure and contaminate the recovered refrigerant

Non-condensables increase pressure readings and contaminate the refrigerant, reducing its quality.

Recovery equipment manufactured after November 15, 1993, must be certified to meet:

Answer: EPA/AHRI recovery efficiency standards for the appliance type

Recovery equipment made after Nov. 15, 1993 must be certified to meet EPA and AHRI recovery efficiency standards.

The safest way to determine how much refrigerant is in a recovery cylinder is to:

Answer: Weigh the cylinder using a scale

Weighing the cylinder on a scale is the accurate way to track the charge and avoid exceeding the 80% fill limit.
