Our takeA 4-valve set listed for R-454B and R-32, with a valve core remover in the box. Use it for the evacuation hookup, and read vacuum on a micron gauge, not on the manifold.The same pump without the overflow switch. We'd spend the little extra on the ULS for anything near a finished floor.

Watch out forMitsubishi's manual says manifold gauges must not be used to measure vacuum.One owner's six-month-old UL failed on a furnace in a finished basement and the floor flooded; there was no switch to stop the furnace.
