A recovery cylinder that is 1/2 full of recovered R-410A at 90°F, in the absence of non-condensables, will be pressurized to: - ️ 300 psig. 16. When using ______, it is essential to take extra measures (heating/striking) to help release trapped refrigerant from the compressor oil: - ️ Passive system-dependent recovery devices on a small appliance with a non-operating compressor. 17. According to the EPA, which recovery equipment maintenance practice(s) should be performed on a regular basis? - ️ Check recovery device for refrigerant leaks. 18. On a small appliance with an operating compressor that has a completely plugged capillary tube, what is the minimum number of access valves needed to evacuate the refrigerant? - ️ 1 valve on the high side. 19. Which refrigerant is most commonly used as a replacement for R-12 in new household refrigerators? - ️ R-134a. 20.
