Your method of releasing the blue line with only a little pressure makes sense, and something another video did not do. Thanks!

[@ChironStellar]

I really appreciate this video. Especially the bit where you only release enough refrigerant into the lines to remove the vacuum pump line under low positive pressure. Brilliant, thank you!

Ok. Sitting here in a cool Sunroom! Just finished installing a Senville 24 K BTU Split system. Probably couldn't have done it without watching your video. Thanks MUCH! I tried a 12K and a 14K Portable floor model AC. Simply could not cool this 450SqFt room. The 14K advertised it would cool (and Heat) a 700 SqFt room. BS!!!! I had to send the 14K back. I've had the 12K so will just keep it or sell it. But as it is rt this moment the 24K is doing the job and it's 94 degrees outside and 78 in here. I had 2 estimates from commercial HVAC companies to install a Split System and they wanted $10000 just to start!!!! Saved myself over 8K doing it myself. Again, Thanks!

One suggestion for wet climates. It would be best to have the refrigerant lines exit the building above the connection points on the condenser to ensure rain water does not travel down the lines into the building.

I was confused with the wiring of Indoor and outdoor unit i was working on and this video cleared it. Great video.

[@johndooley8837]

Thanks for the video. What did you do with the condensation drain line? Water runs out of it in A/C mode. It's a good idea for your pipes to be angled downward toward the outside, same idea as a drip loop. Rain on the lines will eventually enter the building if positioned your way. Regarding coiling the lines, the refrigerant and oil are said to have miscibility. Defined as follows - "Miscibility is the property of two substances to mix in all proportions (that is, to fully dissolve in each other at any concentration), forming a homogeneous mixture (a solution). The term is most often applied to liquids but also applies to solids and gases." I have seen many coiled systems running for years, 10 years for my own systems, with no issues. A coiled line also helps to reduce vibration and noise from travelling from the compressor to the inside of the building. Regarding the electrical wire from the compressor to the inside uiit, viewers need to know that your routing will not work for most installations. The "cab tire wire" connecting from the compressor to the inside unit is bundled with the refrigerant lines in order to get to where it needs to go. I would suggest that people watch other installation videos in addition to this one before starting the install.

[@axeljehovanymendoza]

This is very easy because you can see all the potential things that could go wrong. If this was a finished house with drywall and everything else it’s a little bit more complicated because you don’t really know the variables. Also no stucco and metal mesh to get through. Stucco would make this job take a lot longer because of all the anchoring and such for the line set and exterior electrical runs. In theory if the conditions are like yours it’s easy if not get ready for a lot more work.Still a great job and super clean.

[@Trialnerror]

You're 100% correct. In terms of doing this as a tutorial I thought my setup was perfect because we can see everything but you're right, add time based on your wall situation. Thanks for watching/commenting brother!

[@dallasokra]

Great video. One tip I suggest is reversing the direction of the hole saw when you are going thru vinyl siding,drill counterclockwise, and have less burring.

[@Trialnerror]

Great tip!

[@GreatRockRealEstateDenver]

You can do something similar when cutting metal siding or roofing as well. If you are using a skill saw, put the blade in so it spins backwards and it cuts well with no burrs.

A friend asked about my install and how difficult it was. I shared the link to this video with my comment: "I wish this video was available years ago as I struggled to find pertinent tips and information for installing a mini split." Videos I found back then had no voice but only music...left a lot to the imagination and room for error. Another great thing about these systems is the low level of noise while operating. No hearing protection required unless you've got a fan bearing about to fail.

[@carsutube]

Trial N’ ERROR thanks for this video. A few things I wondered are. How did you get a unit that did not come pre loaded with refrigerant? Did you remove it? Also if I got one that’s what I for sure would have wanted to do so there is no coil left sitting around. Is the pre pressured refrigerant that they put in the unit in the out door unit or in the lines they provide. Assuming their closed pre filled refrigerant systems are done by the company. Again how did you get one where you could fill it yourself? Also when you cut the pipe on the inside. How did you flare the ends of your pipe since we didn’t see how you did that? Lastly when you let the nitrogen out of the lines that come out of the indoor unit. Is that nitrogen just in those short pipes for shipping purposes? It was hard to see what you were removing slowly to release the nitrogen. Thanks. Love how clean your work was. Not OCD to me at all. Well done. I hope I can do what you did when I install one

Great video! Best details about vacuuming line set among all the DIY mini split videos I've seen. Although you say it's simple, I've seen other youtuber DIY mini-split install get into major pitfalls - such as kinking the line set by bending it too sharply, or not actually vacuuming the line set before releasing freon by forgetting the shraeder valve insert. So it's possible to get into serious trouble if you are not careful with DIY mini split installs.

How did you install the drain lines? I am going to install all of my lines in the framing and I can't have them slope down continuessly. Do I have to use some kind of a pump? The system is already loaded with the coolant. Does that include the lines?

[@cluginbill]

I have two units like this installed in my server room, and the pro installers did run both drain lines to a pump. Once the pump is full, it pumps the water to a drain pipe. I suppose you could also let it drain outdoors somehow?

[@luiscervantes390]

Good job , keep in mind that it is ideal to have a micron gauge when your vacuuming a system to ensure that you do not leave any moisture as it can cause problems. Also it’s probably better if you can pressure test your flares/ connections by inserting nitrogen in the system as this will allow you to have higher pressure in the piping which can lead to finding leaks that can only be seen with higher pressures.

[@bridges5659]

Just use diluted soap suds or ordinary dish washing liquid around the flared connectors and it will show bubbles around the joint if there are any leaks.. The most effective way is to inject dye oil and use an ultraviolet light to detect leaks but it's time consuming and the dye oil does some damage to the system. 👍

[@doddgarger6806]

I just let mine sit under vacuum 2 hours, didn't budge an inch Then you can run the system and leak test with soapy water so the lines are under about 400 psi, have to do this in heat and AC modes as the suction line obviously swaps and alternates which line is under the greatest pressure

[@DayClanTribe]

@@doddgarger6806 410a is more critical than others and it's very important for system longevity that proper procedures are followed to 410a standards. That included pulling down to a MINIMUM 500 microns and holding. There is no other way to observe this without a micron gauge.

[@rickmarchand5033]

What about your super heat for efficiency. Factory charges are inherently low due to temperature differences.

[@pistolshoy87]

Ax L where the units are made and prechaged for the consumer the refrigerant most time is under charged due to a temperature change from where they are built so you have to convert the pressure on the high side of the system (the reds hose/gauge) to temperature using a P/T chart and take a temperature from the out let of the condenser subtract those 2 numbers and that will give you a superheat the super heat should be between 5 and 20 obviously you want to aim more for the middle of those 2 numbers but this can determine if your unit is undercharged or not

Nice install. Your only one I’ve found so far that installed the lines between the studs. To keep the inside unit flush to the walls were those lines easy to bend or did you have to notch a relief or drill some holes.

[@Trialnerror]

They are easy to bend but also easy to crease so you have to be very careful. They cannot handle anything tighter than say the circumference of a 1 gallon paint can if that makes sense. Just bend them slowly and really watch the lines as you're doing it. If it starts to crease you want to be able to stop before it's too late. GOOD LUCK man!

I ended up putting some pressure treated 1" X 8" boards to give a solid backing for the rack and then like you using lags into the joists. It looks like your siding is either wood or something as solid.

[@bupright]

This is the very best installation video I have seen. I have a question though...you ran the control cable in the same conduit as the main power. Mr. Cool told me this would cause interference and create problems. Did this happen to you? Also, do you know if there is a minimum line length when you shorten the lines? Thank you!

[@bupright]

@@Trialnerror I think I've watched just about every video for the various "models" that are made by Midea (Pioneer, Mr. Cool, Senville). You were the only person who ran the lines together in the same flexible conduit, and I think that is by far the best way. 98% of the installations on KZbin just have the rubber control cable exposed -- or running across the ground -- packing 240 volts! My line set is sixteen feet and I plan to cut off about five feet, so hopefully that will be OK. Just as an aside for anyone else watching this video: My Mr. Cool came with a chintzy 2.5" wall sleeve, constructed of the thinnest, cheapest, most ridiculous plastic. I could see that it would cause problems, so I cut a hole with a 3.5" hole saw, and inserted a piece of 3" PVC for a sleeve. (3" PVC OD is 3.5", ID is 3"). The extra half inch made a world of difference.

[@buggsy5]

@@bupright I believe the electrical code prohibits running low voltage control cables in the same conduit as power cables.

[@bobakleh1397]

When you pull a vacuum you need to check the microns to ensure vacuum is pulled enough. if not, air will be in the system and cause damage to compressor mainly and lose efficiency. second thing, when you check pressure, a vacuum test is good, but you need a micron gauge to really see what the number is, using manifold gauges doesnt really show you much change unless you have a major leak. Other way to check is with nitrogen, most minisplits use 500psi as a test and let it sit for however long manufacture recommends. Another thing, the reason why people coil up the coil is because some minisplits come with linesets that are precharged with refrigerant so you can't just cut open the line or else you need a tech to come out and fix your booboo and recharge/reweigh in the charge.

[@rhybeka]

Any input on why a refrigerant valve wouldn’t open? Having trouble with my high pressure line and I can’t find any help/references anywhere!

A lot of these precharged units need at least 10' of refrigerant tubing.

[@r.a.williamsakablackmullet8325]

15ft

[@MRM-wp4gr]

You said, " the shorter the better" for length of copper lines. If you cut them shorter than the recommended 10ft length, will that increase the refrigerant pressure too much?

[@nedjinski]

Love this video! You are so meticulous and thorough. I have a question about the lines. You cut yours to exact length. Most of the MrCool heat pumps sold now have a specific length set (25ft) that is pre charged. For my upcoming install I need about 8/10 feet max which is much less than the pre charged set. I like the idea of a pre charged set but to take advantage of it you have to go with the length supplied in the kit and then, like in my case, I would have to accept quite a bit of coiling which you say is not a good idea. So would you recommend to get the pre charged set and make it work somehow or go with cutting it to length? There would obviously be some coolant spill and I would have to charge the system the way you did.

[@Cyberbronco]

Nedjnski I’d like to see someone more qualified answer your question. I am in Florida. I’m installing an 18,000 BTU unit for my garage. I’m going to have my extra line coiled up outside next to the unit. As long as the coils are large and there are no sudden bends or kinks I would worried about oil pooling. If you are getting the DIY by Mr Cool then cutting the pipe defeats the purpose and the cost savings. If you want it to look prettier without the extra coiling then you want the regular non-DIY like he is installing here. With the money you save you can buy the tools or call an AC tech to make the connections and vacuum the lines for you. Hope this helps.

[@luisrodriguez4308]

why did you connect the neutral in the breaker box and you capped it in the outside disconnect? The 240 doesn't require a neutral, right? What purpose does that serve connecting to the box when you have the ground connected?

[@Trialnerror]

I explained it in the video. It's for a potential future upgrade.

[@bigdaddytheprofessor1651]

@@Trialnerror that is what I thought, did you disconnect the line(neutral) in the breaker panel

[@robbarmstrong1342]

the mr Cool unit you got was the non-DIY version by the look of the line set. correct?

[@Trialnerror]

Correct! Lines are not under vacuum so it needs to be vac'ed down but it's usually quite a bit cheaper than the true DIY setup.

[@jkepps]

Great video! My only concern was when you were working on that sub-panel (which I assume was energized) with your necklace/chain on. Other than that, Pure Awesome Sauce!

As a general rule, leave all metal jewelry & watches at home. This addresses electrical and mechanical (fingers crushed by rings) safety.

Hi,... I'm sure you would much rather have a " like " than some stranger saying "Thank you" for the video,..... But you got both! Thanks, nice job!... Also esp. Liked the tip about backing off torque on flair and reseating them, sound like good practice to me...

[@Trialnerror]

Thank you very much! Love to know these vids help others so that comment means a lot to me! Thank you so much for watching!

Cool video, very informative. I've installed one and it was very helpful to see people going though the same process. One advantage I had is that here in the UK mini splits like this just plug into a standard outlet so we don't have to touch the main panel.

[@Trialnerror]

Ahh the benefits of living where mains voltage is a reasonable amount to power most anything. That saves a lot of work!

Thank you for this video. I followed your instructions and all worked well. I would not have had the guts to try doing it my self without your detailed explanation .

[@richardzweig9264]

You did a very nice job with your installation video. The only issue I have is that you ran the Control wiring together with the line voltage feed wires. This is an Electrical code violation. For two reasons. First is by no means is the Discount our side allowed to be used as a Raceway for any other conductors other then what the Disconnect services. The second one is that in order for your control wires to run in the same conduit as your feed wires they need to be of the same wire installation as the feed wires. I feel you should make note to this. Reason being is anyone who’s will take this project on and have it possibly filed for inspection from the local authorities will fail inspection. Otherwise you have done a nice job with your DYI- - tutorial.

[@bgregg55]

I missed that. Very good point. Low voltage signal wires running in close parallel with 220v supply lines is a big no-no.

[@markm6444]

Why did you connect neutral in the panel if you left it capped at the disconnect?

[@cesarrosales7793]

With what did you wrap the copper hoses on outside looks clean

[@IMZReady4Anything]

I’m confused as to exactly how much refrigerant you put in there just 1 pound? Or did you fill it to a higher volume call Cameron of Cameron?

[@normala3227]

The unit is pre-charged. There is no need to add refrigerant.
