I installed this unit back in August 2022 and it's still going strong in the Texas heat! Nice video sir.

I just installed a 4 zone 36k BTU Della 220V on my cabin. The install was super easy. I ran one line set inside an interior drywalled wall and that was a tad difficult by myself but it worked out... The only thing I overlooked was to install the drain line under the refrigerant lines... I was worried that I might have water backup and overflow the interior pan but it was fine and drains without leaking. I'm super impressed with the Della unit!

I bought and installed one of these about a month ago, and immediately bought and installed a second one. You didn't mention it, but the wifi programming options and controls are outstanding. Way more features and capabilities than I could have even imagined.

Couple notes: check the minimum inset length before cutting line set. Mont mini splits have a minimum line let length of 10 feet. Golding any shorter will shorten the life of the compressor. My Della had a 10 foot minimum. Also check the manual for minimum clearance from the back of the compressor to the wall. Most are 12 inches. My Della was 12 inches. It looks like your install was less than 12 inches from the wall and your line set was less than 10 feet.

I installed a 9, 000 btu Cooper & Hunter in my office two summers ago. I now have a different Della 12, 000 btu unit than this to install in my bedroom. The listing in the description is for a 230v, the 115v unit I ordered is $100 more. And the C&H unit is now around $850. Not too hard for someone handy to install and the cooling in the summer is great, and heating in the winter is great. Hoping to get all the rooms in my house with mini split systems and my solar panels installed (there on a pallet in my shop right now, haha), then my propane bill will be cut a lot in the winter.

I assumed that these were easy to install. Quite a bit of work and some special tools required. U do great work!!

I can tell you take pride in your work. Looks great

Overall I like your installation. 3 comment:
1. I would not run the lineset inside the drywall. If there is water leaking for whatever reason, it won't leak inside the wall and goes unnoticed until it is too late. I would put the lineset to the outside and cover it with lineset cover.
2. I would check the leak at the connection points after releasing the refrigerant before I tape it up. The pressure in the lineset will be much higher when running in heat mode and will show any subtle leak. Holding the vacuum does not guarantee no slow leak.
3. Minimum lineset length is about 10 ft from the MFR. Does it really make a difference if shorter? I am not sure. Maybe just less efficient.

Very nice install most installers would never go to this much trouble to do an install, I love these mini-splits. I put a Mr Cool 18K in 7 months ago and I wish the conduit cover was made like this one, so much easier to work with. The electrical cover was the only thing I thought was wonky at the time I installed it.

What I heard the best option for coiling up extra line set is to do it horizontally. Since their should be a J bend, you could just make the outdoor J bend near the condenser connection and coil up any additional underneath the condenser, especially since you have it on the mounting bracket. It would be nice and out of the way.

Also, I really like those in ceiling cassettes. I might do something like that for my garage to keep it below 80F in the summer and over 40F in the winter. I have two electric cars and it would be nice to reduce the extremes that they deal with more often.

I just installed 2 Della 36k btu mini splits in my new shop and they work awesome!

[natersalad]

I agree with some other comments about running a drain down to the ground, but gotta make it look good. Maybe small pvc over to the inside corner of the wall and then straight down the corner, painted to match the siding obviously, which would make it basically invisible.

Great video, thanks for the upload👍
March 2021, I pulled the trigger on an Aircon International Titanium Series 12000 BTU Ductless Mini Split Air Conditioner from Wayfair for $683.24 plus tax, & free shipping. Installed myself, had a HVAC buddy pull vacuum and release the refrigerant. I checked today, the same system is $875.10.
Installations are simple if you're handy and can follow directions... I wouldn't hesitate to do it again.

Installed this same unit about a month ago. I already had an identical (12k) unit on the other side of my house and this one took me over the standard ratio of 20 btu's/sqft. It actually enabled both units to run at lower power levels and achieve super stable indoor temps. They work well heating over the winter and dropped my electric bill by over 100$/month over the summer. They seem slightly less efficient in the colder months, but I could insulate a little better. Paid for themselves in less than 6 months. It motivated me to follow through with the solar panel install.

[scottnagle]

Followed your instructions exactly and everything worked great. Your procedures and descriptions are amazing!! Thanks!!!

I installed a 220V Della 12, 000 BTU unit about two months ago. I agree, it was easy, it only took me about 8hrs to install. It took the place of a wall mounted window unit similar to what you did. I also used the existing 220V that powered the existing unit.

I can tell you take pride in your work. Looks great. I can tell you take pride in your work. Looks great.

Great job, and looks like a nice unit. One big mistake (and major NEC Code Violation) was that metal box for the 120v buried in the wall. Huge no-no. You should have relocated the disconnect so you could simply have run the existing power cable directly into it, or installed a blank cover on the existing former outlet box inside. Buried boxes have caused fires in the past, if a splice inside fails.

[lnofgss]

Pretrip from a non pro: for a cleaner install, I mount the disconnect to the bracket. I drill holes and use bolts and nuts to secure it. It’s possible to pull the power wire through the same hole too. Less clutter on the wall.

I installed a 21k btu in my house, its been up about 3 years now and still working beautifully.
