I absolutely love my little 2 cfm cordless Navac vacuum pump combined with the trublu hose and Apion schrader core removal tool. Five minute vacuum down to 400 micron. It’s freakin awesome.
I agree with the comments to put the micron gauge on the 3/8" line when pulling from the suction line. I also believe that you introduced some air back into the system. A small amount, but some air. It happened when you were replacing the Schrader core. Some air went in when the valve was opened under vacuum. The air went into the core tool during the core install.
Which is why you should release a small amount of refrigerant into the system (if pumped down) to pressurize the system and not loose that vacuum. Use valve cores on both suct & disch lines to gain better flexibility.
You really don’t get a proper micron reading when you hook to gauge to the pump but you probably already know that and are doing it for convenience. You’re supposed to have the micron gauge at the furthest point away from the pump. I put my pump on the suction side and my gauge on the liquid with a one hose set up.
My company tell us to do triple vacuum I do it it takes us a lot of time but I know those system will run super clean for 10+ years 🙏 and they just start installing filters dryers in indoors that was by training really good video 👍 thanks for your time on making this videos
Great video taddy Read the triple evacuation, i get we all start somewhere but i giggle thinking a person is knowledgeable enough to know about evacuation but has to be told to get the refrigerant out. All love.
Hi , you can’t have real vacuum reading hooking up micro gauge on vacuum pump. It should be on furthest away service port. I use Navac 2 CFM vacuum pump, Trublue hose and BluVac Pro micron gauge. Great setup.
Excelente, muchas gracias. Thank you, sir. Very helpful. I will finish my trade school course this week, and I need to start looking for the tools. Can you please make a video update about the " starting tool list ". Thanks again.
How do you like the Navac cordless? I just bought the Fieldpiece vacuum and used it for the first time this week, oh man what a game changer compared to a jb industries, don't get me wrong those jb industries from 10 years ago are still runnin strong as long as your changing your oil.. but I pulled a complete vacuum in no time to about 137 microns in like 10 minutes. Thanks for sharing Tad per usual!
Check the specs for the nitrogen. I buy Nitrogen 5.0 (99.999% Pure nitrogen, as a protective and purging gas in metallurgy, metal processing industry, chemical industry, electronics industry and food industry) which has a lower parts per million water than nitrogen sold by refrigeration houses. Another benefit is I own the bottle. Also, avoid cheap nitrogen sold for so-called fuel efficiency BS for cars. With modern pumps I do not see a real need for triple evacuation I prefer a longer test but I'm willing to agree to disagre.

That is awesome!
Hi bro must say its pretty awesome to have those types of tools to work with just makes the job a whole lot easier
Yes it does!
Great video taddy

All love.
I think id put the micron guage on the liquid line port, that way your looking at a true system vacum.
That's a really good idea thank you so much
What makes the suction line micron reading invalid or not a “true” vacuum?

I’ve always seen it done this way
Core removal tool vacuum always! Over here in the UK, the brand is known as Navtek
Excelente, muchas gracias.

You're welcome my friend. Thank you so much for watching. I'll do a video about the tool list.
Taddy Bear (Hermano) I was always thought to open the liquid line first!!!!!!
Wrong it pours oil into the line set..
Why we need a core removal tool? If we dont have one then what is the akternate way
If you don't have one it's okay

You're welcome my brother I like it so far it's pretty reliable.
Awesome video brother thanks for sharing 🤟💯🌎

Sorry but you have your Micron Gauge in the wrong place
2CFM’s😂 You’ll be there ALL DAY trying to use “Squirt” to pull a deep vaccine.😂
lol
Can you put the micron gauge on the blue hose port while you suck down?
relax bro we just met
lol 😆 🤣
yes
Why wouldn't you open the refrigerant before putting the core back in?
not sure
👍
Some things need chords .
