Section 608 regulations · EPA 608 Core. The correct answer, and the reasoning behind it.
Pressure classes, recovery equipment certification, AHRI 700, the sales restriction and the venting ban.
The question
What is self-contained recovery equipment?
- Equipment that relies on the appliance's own compressor to move refrigerant
- A recovery unit that is permanently mounted on the appliance
- A cylinder that comes pre-evacuated from the factory
- Equipment that removes refrigerant without help from the applianceCorrect answer
Why “Equipment that removes refrigerant without help from the appliance” is correct
40 CFR 82.152 defines self-contained recovery equipment as equipment able to remove refrigerant from an appliance without the help of components in the appliance. It has its own compressor, so it works even if the appliance compressor does not run.

Why the other answers are wrong
- Equipment that relies on the appliance's own compressor to move refrigerant — Relying on the appliance compressor describes system-dependent equipment.
- A recovery unit that is permanently mounted on the appliance — Mounting is not what the definition turns on; it turns on whether the equipment needs the appliance's own components.
- A cylinder that comes pre-evacuated from the factory — A cylinder is a container, not recovery equipment.
