Adam Bush video transcript - Vacuum Pump Process (Training video Transcript)
Hi, my name is Adam. I’m here with HVAC Technical Academy. I’m here to explain the vacuum pump process.
First thing you want to do is hook up your low side and high side lines with your ball valves off, obviously, and then connect your vacuum hose to your vacuum pump. You turn the vacuum pump on, then you open up your manifold and your ball valves, and you open up the vacuum. Then you wait for the pressure in here to read 500 microns or below. Until then, you just wait.
It can take 10 minutes, it can take up to two hours from what I’ve heard. Once you reach the 500 point, 500 or below, you close everything up. Definitely close your ball valves before you take the hoses off the high side. Then you turn your machine off and you’re good to go.
Another thing about the machine: you need to open up this ballast here, otherwise it won’t do its job properly. That expels all the non-condensables that you don’t want, which is what you’re trying to do — pull out the refrigerant and get rid of all the non-condensables.
Thank you for watching.
