WebDec 1, 2024 · The hydrocarbon component in R-422B will help move mineral oil around most systems that do not have receivers. Can you charge 422B as vapor? With the system off, initially charge R-422B in the system to 80 percent of the original R-22 charge as a liquid. Note: Charging a system with R-422B as a vapor will reduce system performance. WebQ: Is R-407C a better R-22 replacement than NU-22B? A: NO! R-407C requires the use of POE oil, which increases system conversion and mainte-nance costs. R-22 systems converted to R-407C will have higher compressor discharge pressures, temperatures, amp draws, and provide less dehumidification compared to NU-22B.
