How to Install a Mini Split Heat Pump | Senville 9000 BTU

I installed a Senville 9000 BTU mini split heat pump myself, it isn't too hard to do it yourself if you have any technical skills. The heat pump comes pre-charged with R-410A refrigerant for up to 25 feet of copper lines (comes with 16 feet of lines) but if you want the warranty to be valid the installation must be conducted by an HVAC technician.

A set of AC gauges and vacuum pump are needed to properly complete the installation if you plan on doing it yourself.

Watched a lot of videos on diy senville heat pumps. This one was my favorite, and go to. Got mine up and running now. Thanks for the great vid!

I put an 18k one in at work, the office had oil heat and that was about $6 a gallon to refill. The whole unit cost about what he pays for each tank, this will save a ton of money. Liked it so much put a 9K one in out bedroom and will be adding a 18 or 24K one to the front room soon before this summer

This Senville install video and another Mini-Split install video by Will Prouse are my go to vids. Great job

I like how "wire the unit to the main power and install a disconnect switch" is a five second clip skipping over something that could take hours depending on how you have to get to your circuit breaker, and should be recommended to have a licensed electrician do it so your home is up to code.

That was very informative Sir. Nice work. Update on this unit please .

I installed the same unit 3 months ago. It is a tremendous value and seems to be a good quality heat pump. I did the complete installation. I would suggest a real pressure test with compressed nitrogen before releasing your refrigerant. The cost of the nitrogen and pressure regulator is minimal compared to the longevity of your system. I also used a micron gauge to verify the vacuum pull down— will guarantee full evacuation and leak testing before the pressure test. I used 12 gauge wiring for the 20A circuit for this unit —about a 75 ft run from the switch box in my garage.
To the OP, you did a good job! I hope your system works as well as mine.

Just wanted to say thank you for this video! The way you documented the process was great, clear and easy to understand. I followed along with the install of my 12K BTU LETO and everything worked well! The line set was way too long in my case, so I got to learn how to flare copper lines too but thankfully I got the hang of it with some practice. Thanks again! 👍

Thanks Andrew! I utilized your video for my Senville install. I never did a mini-split before. It felt great when the cold air was flowing.

Installed the 9000 BTU 240 volt version few weeks ago. Good job keep the videos coming. The 120 volt version is the Leto series and the 240 Volt version is the Aura series. The leto is good for -15 Celc and the aura series is designed for colt climate down to -30 Celc. Keep up the videos

[gggamezzz]

Your video was a huge help in my installation. Easy to follow instructions and good visuals.

[JonTheChron]

Bought a 28k unit directly from senville as they are located a few minutes from my house, I have yet to install it but will be doing so in the nextf ew weeks! I'm excited for this!

[alfredoleon]

I vot the same drill for 100 bucks at home depot. It's bad ass. And your very good verbal instructor. I'm a novice home DIY husband

[wzrdstrm]

Thanks for this, much appreciated. The wire terminals for the inside unit are very soft and strip out easy, take care here.

[oasisoflasvegas]

Nice! Now all I need is to figure out the electric side of it. We have power right where we plan to put the condenser, and we’re just using a 110v unit too, max draw is like 10amps.

[shmoto]

Thank you thank you for sharing this information on your install of this unit. It gave me the confidence to install the same unit successfully. Thanks again!

[EliAlexanderClark]

About to install one on my shuttle bus camper. Wish me luck, and thanks for the video! Extremely informative and thorough!

[schizy]

The vinyl wrap, if wrapped up from the bottom, then has the overlap down so that water doesn't enter the wrap. (a suggestion)

[SSspecklez]

Not bad, break your vacuum in ur suction line before taking ur hose off. Do a pressure test after the vacuum, and nylon doesn’t go on the back of the flare

[disc]

Thanks so much for this! Planning on buying the unit and this is exactly what I needed to have confidence I could install it myself.

[Gyppor]

Thanks for the how-to on the refrigerant work!
