Wiring a Mini Split System, Step by Step!

In This Installation Video, I Show How to Wire in a Mini-Split Air Conditioner and Heat Pump System. I go over How to Connect the Power Wires from the Disconnect to the Outdoor Unit after Installing the Whip. I also show the Low Voltage DC Communication and High Voltage AC Wires from the Outdoor Heat Pump Unit to the Indoor Head Unit. On this Mitsubishi Ductless System, we are using the Southwire EZ IN to connect the outdoor unit to the indoor wall unit. The EZ-IN cable contains 4 THHN wires, are shielded with MC and rated for outdoor use. I also show the EZ-IN outdoor connector.

Your attention to detail was spectacular! Attaching the ground wires first, always Best Practice...I just enjoy seeing technicians doing the best and proper procedures, well done!

*Solid, **Fastly.Cool** and gets the job done. For rooms where window-mounted air conditioning is not an option, this works very well. Easy set up, rapid cooling, and great design.*

Nice thorough video, makes it all look straightforward and clear. Now back to real life for someone who does not do this for a living. On my indoor unit, not a Mitsubishi, for starters I cannot even find the screws to attach the 4 wires to. The 40 page instruction booklet is amazingly confusing and incomplete, mostly leaving out a lot of things and seeming to assume that you are in the business as an installer. I can hardly believe that the mini split I purchased (Home Depot) is certainly not as easy as installation always appears in these Youtube videos. I have many questions, and am still slowly plugging away at it. I still have no idea why a lengthy instruction booklet has to leave so many unanswered questions. Incidentally, I am a fairly experienced person with many tools, and pretty experienced with electrical installations too. But this is my first mini split. I blame most of the problems on the poorly written instruction booklet. This will also require buying a good many more specialized tools for hundreds of dollars.

Great installation on the wiring and keep up the good work! 😀👍

I’ve noticed a lot of these do it yourself mini split videos don’t go into great detail step by step in wiring from the electrical panel to the unit. What the breaker looks like, what size breaker, how many wires what size wire and how it’s properly installed so no one gets electrocuted or shorts the system out

[aryrobmedina]

Videos are bad ass learning so much from you thx man 😀

When wrapping a stranded wire under a screw twist the wire counter clock wise before wrapping the wire clock wise under and tighten the screw. This stops the stranded wire from being squashed out from under the screw while being tightened.
When using a crescent wrench apply the major pressure against the head of the crescent not on the jaw or bottom of the wrench .

Great vid, makes me want to get a mini split

[throttlebottle]

thought I was going to be able to complain about not putting the anti-short bushing in at first, then you did it :)

[stephenbennett]

The most amazing HVAC training . Keep up the great work

[hczmlup]

Great advise! And now, I want to know if I can install the outside unit on top of the roof;

Wich would be about 3 to 4 feet above the the level of the internal unit and about 10 feet apart

[LakayRicky]

10:10 VERY much appreciated
10:45 thank you very MUCH

[rotaxrider]

Do you have a video discussing if you can power a mini that is powered by a portable generator for power outages?

[WindersRanger]

Amazing how clear and concise information can point someone in the right direction. Thank you! Just one quick question. Im looking at installing a different brand mini split but the line connections look very similar. In my case i have a 50amp feed line with a neutral which you didnt mention here. The mini split doesnt need the neutral? Just two 120’s and the ground?
