I just bought this unit and noticed that the ground was missing the screw on their, did you have to use one of your own or was one inserted on there that I may have overlooked? Thanks for the help!
That's why pulling a vacuum is necessary. I got an AC installer friend to pull the vacuum for me and he confirmed that it needed to be done. I wanted to put that in the video, but he didn't want to be on camera.
The lines are open to the air. If you don't pull a vacuum then air will be in the lines, which will degrade it's performance. That is also in the manual. I got an AC installer friend to pull the vacuum for me and he confirmed that was the case.
Personally, I’ve done gas propane and natural gas and HVAC for a long time. I have never used anything on a flare fitting….ever. I have never seen one loosen up from vibration or anything else for that matter. In gas work, it’s actually against code to use anything on the threads. I have just recently started using Nylog on the flare only. And that’s only because soft copper lines have gotten so much thinner in recent years. When you compress the copper flare to the brass fitting, it compresses to a certain extent and “springs” back so to speak, putting force on the nut and acting as it’s own thread locker, kind of. But, I would never use loctite on brass fittings, ever.
I'm almost positive that your AC guy was referring to Nylog, not Loctite, even if he said "Loctite". They kind of look similar (the blue Loctite anyway, not red), but in HVAC work, the Nylog is used not on the threads (nothing goes on the threads for brass/copper), but on the lip of the flare itself. Also, two more suggestions if I might? - Use a hammer drill for drilling through brick or other stone/concrete stuff. It's an absolute game changer and what it was made for. That half hour brick hole of yours would have taken about 2 minutes, no kidding. - If you're installing more mini splits in your future, consider getting your own flaring tool to cut your copper lines to size. They're not that expensive for a good set. Same with a basic vacuum pump and gauge set. You'll save a LOT of money over hiring your AC friend to come do this stuff and won't have to wait on him.

Mind had the ground screw. It may have come unscrewed and may be in the unit. It should be copper.
@scottswinda The Della unit is charged but the lines comeing from the indoor unit are not charged like a MrCool mini.

P
What is the adapter size too pull the vacuum is is 5/16 or 1/2 inch adapter
5/16
Hey if that mini split is precharged it shouldn't need the lines vacuumed

@@scottswinda4727 Non-condensibles are one of the biggest problems with compressor failures.
The one part I needed to see you don't show.
What do you need to see?
La parte que quería ver no la enseña 👎🏻
I want to se da vacuum part
you should never us loctite on flare fittings
Why not? I would like to know. I always have and never had any problems from doing it. My AC guy said to do it.
@@MikeM100 it goes against best practices, loctite should never be used on brass fittings

The most important parts were omitted what a waste.
