- CBelow 15 psig.
- DBetween 45 and 170 psia.
Why A is right
40 CFR 82.152 defines a low-pressure appliance as one using a refrigerant with a liquid-phase saturation pressure below 45 psia at 104°F, such as R-11, R-123 or R-1233zd(E). Between 45 and 170 psia is medium-pressure, and 170 to 355 psia is high-pressure.
