@hvacknowitall: How to check decay with a single hose... When the micron gauge is close to the pump, (which is okay if you perform a decay to test) it can read lower than the actual system pressure. That's why we must perform a decay test by isolating the system from the pump. We used the @NAVAC NRV1 core tool in this video to perform this test (NRV2 also available). We used the NMV1 micron gauge and NP12DM vacuum pump as well. @supco_hvac Umbrella keeping us shady #hvac #hvaceducation #hvacknowledge #refrigeration #hvacinstallation
you’re supposed to have the micron gauge as far as you can in the system from the vacuum pump which would be the other line and you can still do that with only one hose

Don’t those Navac micron gauges complete their own decay test without having to close off the hose?

Decay test. process only matters to get a pass on the decay. if you can pass decay, it is right.

Do you remove the Schrader too?

Why not move it to the other valve?

Too many leak points remove the valve set up, put the micron gauge on the liquid side

Shouldn’t you valve off your micron gauge? So when you break the charge it doesn’t hit the micron gauge?

The rule we hold is after below 2000 micron we close the valve from vacuum pomp for at least 30 min and is must stay below the 2000 micron 🙏🙏🙏
