🔍 Key Concepts

• Look at which device does NOT have a storage tank built into it and would therefore need an external recovery cylinder. • Think about a unit that only moves refrigerant from one container to another without cleaning, drying, or testing it. • Distinguish between simple transfer pumps and larger machines that recycle/reclaim or process refrigerant.

💭 Think About

• Which picture shows a device that appears to be just a small compressor or pump with hose connections, but no visible receiver tank attached? • Which units look like they include filters/driers, large tanks, or test gauges that would be used to process or analyze refrigerant rather than simply recover it? • If you had to connect a separate DOT cylinder to collect the refrigerant, which device here would need that cylinder in order to function?

✅ Before You Answer

• Verify which illustration lacks any large built‑in cylinder or receiver tank. • Check for signs of processing equipment such as multiple filter canisters, complex piping, or large control panels; these usually indicate recycling/reclaim equipment, not simple recovery. • Confirm that the device you choose could only move refrigerant into a separate recovery bottle, and by itself cannot store or test the refrigerant.
