Nice, I did a similar Zone Air DIY mini split; it's been working great.

Maybe somebody mentioned already but when using a crow's foot with a torque wrench - the crow's foot needs to be at 90 degrees compared to the wrench handle to achieve correct torque. Thank you for making great videos!

The power line into the exterior disconnect needs a grommet or other means to secure the cable to prevent shorting.

HVAC service tech here, love the install. My only comment is that you can’t rely on time for the vacuum pump. The industry standard is to use a vacuum gauge and suck the system down to 500 microns. This is the standard to ensure that there is 0 moisture left in the system. Keep up the good work!

Pro tip from my HVAC buddy, don't mount it completely level. Give it a degree or two with the drain side being lower. This will help prevent any draining problems from the unit. Apparently that can be a thing possibly due to settling.

The electrical connections as shown at the <a href="https://www.youtube.com/watch?v=AMa6YRUwL2I&t=2120">35:20</a> mark are dangerously poor. The wires needs to wrap at least 3/4 of the way around the ground(green) terminal screws. The one on the right is barely under the grounding screw. On the terminal block you have similar issues. The the L2 line side is especially bad, with one of the strands of the wire not even under the terminal screw. With stranded wires (especially connections to motors!), you should use crimp style split ring (or ring) connectors. Remember, there is a motor running on the condenser unit, and near 24/7 vibrations as a result. Your only ground is from the whip, and if it fails, and either one of the L1/L2 load connections comes loose and shorts against the metal enclosure, you have just energized all the metal parts of the entire system; potentially with lethal consequences.

I installed my mini-split a couple of years ago myself by watching YT. I had to watch multiple different videos to get all the information. I wish I would have had this video then. You covered everything in one video. Nice job!

They actually make NM connectors that are required by the national electrical code when you bring a piece of NM cable into an enclosure, we just don't poke that thru holes.

I installed my mini split lower and further away from the wall so i can clean it with ease. The fins in the back get dirty very fast and need to be cleaned twice a year.

You also need a romex connector in your wire in the disconnect per code

Thanks to your video, I had confidence to purchase and install a mini split for my 200 sq ft workshop. Got a Rovsun 9K ($399 on Amazon) system and installed it on a set of brackets on the outside wall. I love it!!! We already had a system installed in our house, a Daikin 20K unit with three heads, but it was professionally installed. I never knew it could be so simple.
