The question

A technician builds a homemade pump rig to recover refrigerant from refrigerators. Why can't it be used for the job?

• AHomemade rigs are allowed if they reach 90 percent
• BHomemade rigs are allowed on units under 2 pounds
• CHomemade rigs are allowed whenever the technician holds Universal
• DRecovery must use equipment certified under 40 CFR 82.158Correct answer

Why “Recovery must use equipment certified under 40 CFR 82.158” is correct

Section 82.156(b) requires recovery from small appliances using a recovery and/or recycling machine certified under 82.158. Only equipment made before November 15, 1993 can be treated as certified without lab testing, and only if it meets the performance level.

Why the other answers are wrong

• Homemade rigs are allowed if they reach 90 percent — Equipment made after November 15, 1993 must be certified by an approved testing organization.
• Homemade rigs are allowed on units under 2 pounds — There is no charge size below which uncertified equipment may be used.
• Homemade rigs are allowed whenever the technician holds Universal — Certification of the technician does not replace certification of the equipment.
