Della Mini Split AC Installation Step By Step 2024 | Total Installation

The Della Mini Split is easy to install and works great! This mini split is the 12,000 btu unit capable of cooling up to 550 square feed. The refrigerant is included in the outdoor unit. When installing this mini split you will need to pull a vacuum so that the copper lines will be filled. This unit runs as 27db with the silentmax system so the unit is very quiet. This Della mini split needs 240v power. It is nice to have the power and disconnect at the unit.

I just finished the install of a 2 ton della mini split. And it works great, thanks to you my friend! When you come to LA, I’ll buy the tacos and the cervezas. Thank you sir

[@sethcraftworkshop]

That's great news.Happy to hear the video was helpful. I'm looking forward to the tacos. Ha ha

I installed the 1800 btu unit iin my 20x30 shop in January. I'm very happy with it. I used a pvc downspout to cover the lines. Split it with a utility knife and you can spread it aesily and it will close right back up.

[@jllaine]

Thank you for a detailed installation, that was worth watching a longer than usual video.

[@sethcraftworkshop]

Thank you for watching. This install was nice. The unit is working well.

I was planning to do a split unit install, this came very handy.

[@sethcraftworkshop]

Awesome! It is nice to have ac in the shop. Installing a mini split is not too bad.

[@mtay65]

Very well illustrated. Thanks, dude.

[@sethcraftworkshop]

Thank you! I hope it helps.

[@Jhpc399]

Very Nice one. Well done! all the way from Bulgaria

[@sethcraftworkshop]

Thank you. This install sure has been nice for these hot summer days.

[@philliphall5198]

I’m seeing more and more people doing there own ac work now and learning how to solider the connection on big homes units

[@sethcraftworkshop]

I bet it opens up a lot of mistakes but I like seeing people learn skills like this.

[@nicolasmuniz9452]

Just replaced a Pioneer 18000/18 seer with a Della 18000/22 seer, I could never get a response with Pioneer, bad evaporator motor, then fried board due to wires pinched at board door from factory, Della very well built, made Pioneer look like tin can junk, Della almost the size of a 24000 due to better seer rating, same price and a promo was in effect, WiFi and better remote functions.

[@sethcraftworkshop]

I have heard from more than 1 person that pioneer is not great for communication. nice to hear that you got your della system installed and its working well.

[@johnisley4578]

Pro work, Good stuff.

[@sethcraftworkshop]

Thank you. Its nice to have this mini split in the shop!

Great video Seth

[@sethcraftworkshop]

Thank you. This unit is working well.

[@juanmaduro872]

Thats is a good video i normaly i install those ac in 30 min it i work with allot of ac frome midea or gree

[@sethcraftworkshop]

Thank you. Because of the video it took me a while to install but its not bad when not filming.

[@wanaraz]

When you make the bends with the copper do you just do it by hand? Thanks.

[@nicolasmuniz9452]

I like to make new flares, also trim lines to size, I never really liked factory flares, usually kind of ragged.

[@sethcraftworkshop]

New flares are nice. I do not have the tool for that.

[@carltierman4202]

The compressor holds enough refrigerant for a 16' long refrigerant line. If you change the length of the line you need to compensate for either taken off some length of line or adding extra line. Mine came with 16' line. Others have 24' or other length of line

[@jameszzh]

what is the diameter of the hole in the wall?

[@cfife90]

What are you going to do with the excess? I ordered a 2 zone mini split from Della, and main floor is only about 8’ from where the outside unit will be.

[@sethcraftworkshop]

My install location only gave around 2 feet of extra line. It will just be placed under the building. You will want to lay your extra line down horizontally if you are not going to cut it. Coiled but horizontal.

[@EngineersHomestead]

I've been debating which mini split to get for my 10x20 detached office shed (cathedral ceiling), got a few questions for you Seth: 1. Did you run 12ga wire? What size breaker? 2. Any reason for Della over something like Senville? I don't plan to buy DIY kits so will end up buying the pump and adapter like you. 3. Thoughts on 9k vs 12k btu for my space? I plan on going 240V model either way.

[@sethcraftworkshop]

It is nice to have AC in the shop! 1. I ran 10/2 for the mini split. You should be fine with 12/2 for a 12,000btu unit. 2. Della seems like a nice unit. I have only used Della and Mr. Cool. I do not know about Senville. 3. The 12k has not had an issue keeping my 20x30 cool. If your place is smaller the 9k would work. many of the 9k are only 120v.

[@jameszzh]

Della is from TCL in China. Senville is form Media in China. As I know, both are good manufacturer. But Media is a little bit better in China and more qualified and more expensive.

[@user-oy4qp9pq6i]

@@jameszzhSome sites have reported that Senville builds Mr Cool and Pioneer.

[@workbenchz]

Interesting that Della precharges the outdoor unit with enough refrigerant for the entire system and you needed to vacuum down the lineset.. The other one you did had a precharged lineset and both units. Did this give give you more or less confidence that the lines are free of contamination from the air?

[@sethcraftworkshop]

The other unit was a mr. cool diy model. it did not require a vacuum at all. Both the indoor unit and outdoor unit both had refrigerant but so did the line-set. On this Della unit you have to have the vacuum to pull the refrigerant through the line-set. So far so good. it is running for well over a month with no issues.

[@swamphox1]

I have the same unit and about to install it. At 11:35 you pull down the tabs on the bracket and I don't see the purpose of these tabs. I don't see where they go into the inside wall unit. Can you please explain this?

[@sethcraftworkshop]

(The manufacturer had me remove the clip showing these because one fell down.) They are only there to hold up the indoor unit while you install the electrical wires. The tabs do not hold the unit on the wall.

[@JamesChandler-xl1mx]

On your gage lines. Do I need to remove the valve stem?

[@sethcraftworkshop]

Not on this one. Because I am not adding any refrigerant there is no need to remove the valve stem.

[@davidwoodall9308]

Why do you need an adapter to hook up the low side? Will the line from the vacuum pump just hook up correctly?

[@Katana_00]

Normal with mini-splits. Read up!

[@sethcraftworkshop]

The thread size on the vacuum pump is not the same as the mini split. The adapter is required to make the connection. This type vacuum is designed for several uses.

[@sethcraftworkshop]

Yes that is correct.

[@Houseb1859]

Why do you have to turn on the gas and check with soapy water? When the pipe is disconnected, the air conditioning gas escapes to the outside, which pollutes the environment. If the vacuum does not decrease within 30 minutes, the system is sealed!

[@mikafoxx2717]

First off, this is the way you're trained to do it because if you remove the guage before releasing the gas you let air into the system instead which is much worse. This has zero ozone depletion so a tiny spurt of something thats got higher global warming potential is less bad than your day's driving to work. This is considered diminutive losses - you need to purge guages and other stuff with refrigerant in use but its far less bad than scrappers cutting open and relasing hundreds of pounds of gas a year - which is who the fines are really meant for.

[@Houseb1859]

@@mikafoxx2717 You shouldn't do it like that in Europe. In addition, there is a loss of refrigerant in this way.

[@mikafoxx2717]

@@Houseb1859 How do they do it in Europe then? Let air and condensate in and make the unit die three times faster? They use less harmful refrigerants while we still maintain stuff running R22. R32 is much better at only 675x CO2 and zero ozone depletion and R290 is legally ventable to atmosphere in any quantity because it's just 3X CO2. 1234yf is also like 1x.

[@NSC3041]

Mine didn't leak over 30 minutes but it did leak over 3 days

[@swamphox1]

@sethcraftworkshop No help with the tabs? Really curious as to why they exist because they seem to serve no purpose and you pointed them out like they do.

[@sethcraftworkshop]

Are you referring to the two metal tabs on the bracket? Those are designed to prop the unit up while you get the electrical work installed. I did not find them to be very helpful.

[@swamphox1]

@@sethcraftworkshop Yes, those are the ones and I get it now. There is nothing mentioned in the install manual. Just wanted to make sure they were not part of securing the unit. Nicely done instructional video BTW, very helpful.

[@maxwelligwe1128]

Mine is showing a P2 error message and not sure what to do. Not cooling and fan stops spinning

[@sethcraftworkshop]

That error did not show up on my system. have you tried customer support?

[@rafhype3088]

could I connect this to a standard 110V indoor outlet? I can’t use a mini breaker outside

[@sethcraftworkshop]

This particular mini split is for 240v. I believe the della unit that is 9000 btu is designed to ruin on 120v.

[@jameszzh]

you need to buy a 120v VERSION. Then, you can do it.

[@mikeharmon8733]

Why are you using soapy water to detect a VACUUM leak? There would be no bubbles, right?

[@sethcraftworkshop]

The primary reason I use soapy water to detect a leak is because the instructions say to do so.

[@Katana_00]

You’re absolutely right. Bubbles would be detected after a positive pressure test with nitrogen. Obviously a vacuum would not produce bubbles.

[@user-ud6mi8pp2b]

He opened the valve for 5 seconds, so it would have pressure in the line.

[@ashtonalbritton8725]

So needle moved from -30 to right below 0. Is that an issue?

[@sethcraftworkshop]

If your unit moved from -30 to 0 that means you have a poor connection on one of the lines. The vacuum was lost and the refrigerant will not stay in the line.

[@ashtonalbritton8725]

@@sethcraftworkshop thank you for the reply! Yes I found the leak in the high pressure side. All good now!

[@whowantstoknow8492]

No nitrogen test ?

[@sethcraftworkshop]

I did not do a nitrogen test. Just followed the directions of the mini split.

[@MarquisZellars]

Did you add any freon

[@sethcraftworkshop]

This mini split has the refrigerant included within the outdoor unit. A vacuum is pulled and the refrigerant is released from the outdoor unit into the line set. Then the system is charged. No additional refrigerant is needed.

[@mdaljev1]

It is the same as mine, sold under Elit brand, but true is, this it TCL from China!

[@sethcraftworkshop]

Seems commonplace to have a rebranded unit from the same manufacturer. So far I am pleased with the mini split.

[@jameszzh]

I tried a lot to find who is the manufacturer, but failed. Thank you for this information.

[@user-vt1ri1zk2v]

@@jameszzh the Della mini split has an I feel mode setting which is a Gree option on mini splits,so it most likely manufactured by Gree,the world largest manufacturer of air conditioners/mini splits and they are EXCELLENT units especially if you get the cold climate triple cylinder 2 stage compressor, the leader in the industry.Most mini splits(almost all) have parts made by Gree in them

[@RealGenX]

Thanks for the details!

[@sethcraftworkshop]

Happy to help!

[@buffalosoldier7360]

Not a complete install shown, you left out the wiring at the breaker…

[@sethcraftworkshop]

It's beyond the scope of the install. That is more of an electrician thing. But it was simple. Just ran 240v out to a switch.

[@bonexsher]

hurts my eyes to look at this 😪

[@sethcraftworkshop]

Was it like a bug to a zapper? lol

[@Katana_00]

Why? What went wrong other than bubble test.?

[@eb1888.]

You edit out all the minor installation difficulties anyone doing this will encounter. This deletes your solutions and possibly attempts. That footage would be the most important for a person doing this for the first and likely only time. You had all that important info. Your video has much less value.

[@sethcraftworkshop]

This was my first install of a mini split that required a vacuum. The only things that I removed from the video were the filler bits. There really were no issues with the install. The value of the video is still high. (I have been building things for 13 years so perhaps I have more install history than some people but the mini split was not hard.)
