Your method of releasing the blue line with only a little pressure makes sense, and something another video did not do. Thanks!
Great DYI tips. Backing off and re-tightening the flares. Remove the service line with only partial refrigerant pressure. Simple and intuitive... for the DYI kind of person.
This is the most comprehensive mini-split video I've seen... and I've watched them all. Most of them leave out too many steps. I'm one of those neurotic DIY'ers that has to watch every video before I tackle an unfamiliar project. I'm ready for this now. Thank you for this one 🤟.
Wow! Thank you very much for the awesome feedback and for watching man, I appreciate it!
I'm with you, I guess that I'm anal like that, lol... But I've got to get it right.
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!
I did it! Just finished installing an Alpine 18k btu mini split heat pump in my living room wall! Used this video to check each step! Thank you for a great tool for us DIY’s!
Way to go!!! Not many other DIY projects are better than putting one of these in then sitting back and enjoying the cool breeze!!!
Our electricity coop is going to peak time charging, now I can run my mini split for peak periods and avoid the extra charges I would get by using my whole house heat pump system.
This is the cleanest install I’ve seen. No extra hose running loose outside. Helps to mount it on the house to keep it clean.
Can you hear the outdoor unit from inside? (because it is mounted on the wall...) I'm still selecting my mounting method. (BTW - Nicely done video!
I do commercial AC, and I must say you did a great job.
Thank you very much!
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.
Very nice! Clear, straight forward video.
Whoever wired the main service panel is to be commended.
The wires are trained straight and orderly from the breakers to
the feed pipes.
A sign of a pro.
Thanks for the video.
That was me and thank you! I have a little OCD when it comes to wiring lol.
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!
Congrats and GREAT JOB getting it done on your own! Letting me know my videos help means the wold to be, for real. Thanks for taking the time to let me know and congrats on the massive savings! Take care brother.
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.
You made seem so simple thanks! I’m an electrician apprentice and I thought it was going to be harder but so far its looks fun to do.
You're welcome!
@@Trialnerror Hi did u use a double 30 amp breaker or 20 amp. Did you just use the 20 amp breaker and oversize the wire for future needs?
Nice video on the vacuum test & alternative way to do a small pressure test. Doing it yourself voids the warranty though on most units, so it's a personal choice.
not on the "DIY" line of Mr Cool. They state on their website installing the "DIY" line yourself does not void their warranty.
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.
Great tip!
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.
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.
Forklift. No household is complete without one.
🤣🤣🤣🤣
WhAt?? You don't have forks?? one person can lift it relatively easy but if you have a way to make it easier go for it.
Thought it came on the box.
Every dummy has a forklift.
Up north……TRACTOR with loader and/ or backhoe
"A proud 5 and a half"
I see what you did there. Thumbs up
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.
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!
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.
Thank you very much. That means a lot to me to know my videos help people out. Thanks again!
Step bit works well for reeming boxes/disconnects for whip
Happy as a midget at a mini-skirt convention. Awesome.
Great stuff installing one in my mancave in Australia. Really needed the gassing explained well. I'm a licenced electrician but needed help on the charging thanks.

Where did you get your hvac vaccum pump? I'm thinking of picking one up from harbor freight. They have a 2.5 cfm pump for about $90, but that sounds really weak even though it's a good price.
@@intrepidtato2662 Link is in the comment you replied to. The Harbor Freight one isn't really a good price when you compare it to the one I linked that comes with the whole gauge set too. Good luck!
@@Trialnerror what is the electrical box for the outside with the on/off flippy thing called or do you have a link? (Sorry if that's too technical...) I've got a split coming from Amazon and was looking at install videos, my brothers an HVAC monkey but he's on disability so I'm doing as much of this as I can without bugging him then having him come over for a final inspection and to give the thumbs up on the turn on...
Hey quick question what generation is the unit? Also is the Freon in the unit itself? Or the lines like everyone saying. I’m confused here
This video made me realize this is way over my head and for that, I thank you.
You can do it!
Just google and youtube for a week on this subject, and you can.
excellent video. by the way use a regular torque wrench with a claw type open end wrench to torque
I was confused with the wiring of Indoor and outdoor unit i was working on and this video cleared it. Great video.
That sub panel is on point. Thanks for the video. You make me think I can do this. At least better than some other people on you tube.
Really love hearing that. Take your time with it and don't get overwhelmed. One step at a time and it will be done.
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
Very well done guide, I too have seen many other videos coil up the remaining tubing. I decided to take an extra step and have a AC guy come out to shorten my lines and charge the system.
Nice video and very informative. I just purchased a 24k DuctlessAire and installing this week. This will make it much easier to accomplish. Thanks!
Good instructions and overview. I have an HVAC guy do my final connections, but find installing the rest of the unit to be reasonably easy.
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.
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. 👍
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
@@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.
You sir, have underestimated my dumbness.
Solid video. Sure wished I would've found your video before I installed mine. I was stressing out that the colors didn't match on the indoor unit or the outdoor one. My OCD caused me to overthink things and my wife just said "what does it matter the color as long as 1 to 1, 2 to 2, and 3 to 3?".
Have watched loads of clips on youtube now. This is by far the best explanation I've seen of how to vac test and charge lines using diy equipment.. Thank you very much. Now off to fit mine before the 'heatwave' hits next week in the UK (with a lot more confidence!) SUBSCRIBED
Great to hear!
Maybe I missed it no drain line needed? Did you run a nitrogen pressure test through the system?
A vacuum pump can be rented at any rental business that rents Core Drill rigs,the vacuum pump rent for around $10 per day,rental place i work for we rent vac pumps all the time for people doing mini split aircon systems
You're breaker box is so clean and perfect....I LOVE it!!!
Bro lost me wit the “that’s what she said”😂😂
Subscribed based on the "this is the best youtube channel, I ever made" comment and various AVE references. Great work on the mini split, I guess. HA!
Thanks and welcome! AVE's lingo just sneaks into your speech if you watch him enough doesn't he?
@@Trialnerror He is pretty sckookum indeed. Your AC project was not hoopa jupped at all.
Very nice job, you do not have OCD on the electrical panel...you have pride in your work
Thanks man, really appreciate that!
I agree. That is how a competent and conscientious electrician wires a panel.
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.
I missed that. Very good point. Low voltage signal wires running in close parallel with 220v supply lines is a big no-no.
first video I've seen with the lines in between the studs. I like that idea. Did you end up putting insulation over the lines? What about condensation on the lines? Is that a potential issue? I really like that idea. I have a small she-shed and am planning on installing a small unit. Wife is particular about looks and having the lines inside is very appealing to me. Thanks for the video. Also I don't see where your drain comes out?
Yes I am doing the same. Those big cover drain pipes are awful. Just concerned I may not able to bend lines enough to do that.
"The best CZcams channel I've ever made" Exactly
thank you for doing this install vid. I am a visual learner and this helped me to make my selection for the minisplit.
So you mention oil traps due to coiling the excess line, but the view of your outdoor unit shows an oil trap due to your lines exiting the wall below the fittings on your outdoor unit. Great video, I'm still on the fence about these DIY units.
can i install one of these units on my home which has the 40 year old a/c unit installed in the attic now to replace that one to maybe be able to provide cooling to two seperate bedrooms with one unit to be able to get rid of the attic unit?
would make it alot easier for me than getting a new unit up in the attic and complete the install.
Yes but you likely want a multi head unit. 1 head unit per room
Was about to watch this video but then realized it was for dummies
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 .
Cleanest setup I've seen on here. Congrats.
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.
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!
@@Trialnerror I was thinking of getting a kit like this: www.amazon.com/gp/product/B08SFZP9W2/ref=ewc_pr_img_1?smid=A3DLN7K1UTIF0F&psc=1 but it sounds like these pipes might not be able to bend that much. Would this be too much on the 1/2 and 1/4 pipes (I have 18k and 9K indoor)
What about your super heat for efficiency. Factory charges are inherently low due to temperature differences.
Can you further explain what to do with this ?
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
@@pistolshoy87 GREAT info Marc. Thanks for adding it, I'm sure that will help a lot of people thumbing through the comments!
Thank god a fellow tech watched this
My first clean sub panel i have seen on youtube so far ...no this is second one ..will prowse panel is clean too
A lot of these precharged units need at least 10' of refrigerant tubing.
15ft
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?
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?
This is the pump they used:

What do you do for a living? Not a bad job for a novice you obviously have a mad engineering mind 👍
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.
in all fairness, the Mr Cool line is made as a plug 'n play with NO vacuuming required.
Great video, but you forgot to show what you did with the drain line and how you ran it. along with insulation of the lines outside.
Yea, I muffed that up. I just ran it down and out of the same hole the lines run through. Sorry I didn't show it on camera but just keep gravity in mind and you'll have no issues. Thank you very much for watching!
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!
@@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 CZcams 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.
@@bupright I believe the electrical code prohibits running low voltage control cables in the same conduit as power cables.
Buggsy5, the control wires need to be 600V rated to be run in the raceway with the power wires. Also the unit may not have been UL tested for this installation.
@@buggsy5 They are not low voltage, the outdoor unit provides 240v to the indoor unit through this 600v rated cable. That said, I believe they are still technically suppose to be in separate conduit but I like to live dangerously lol.
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.
Ahh the benefits of living where mains voltage is a reasonable amount to power most anything. That saves a lot of work!
@@Trialnerror We need it to power our 3kw electric kettles to make tea....
Thank you for the straight forward info. Appreciate it. And my OCD is very pleased as well🤣😎
Crows feet with a tq wrench work great, but the bigger one is like a 7/8 or 15/16 so need to be a big set, smaller one is 16mm maybe
This looks so simple I'm going to ask my mom tu do it.
oldkid6 do you have an insurance policy on your mom?
8.19.21 Nice video. Liked how was shown using the vacuum pump and cutting the excess tubing. Liked the idea of not rolling up the excess tubing if can not cut and flare. Thanks again.
For other cheapskates like me who only plan on doing this once, O'Reilly's Auto Parts and probably other auto stores provide free rentals for the pump, gauges, and flare tool. I have not tried it yet but it was listed on their website as a rental option.
Great to know thanks
When you DIY, all tools are FREE!
Warning this is for DIY homeowners only.
I have trouble putting in the window units, guess I'm not DIYing this 😂
They make an actual DIY system that is designed to be easier to install and has the full manufacturer warranty even when not installed by a professional. That is what i am looking at buying right now.
The best aircon installation guide No shortcut. Thumbs up
Most people who are installing aren't doing it in an unfinished space, so while it's very helpful to tell those of us who don't have the flaring tools or the tools for adjusting down the coolant levels for using less line than comes with it or the knowhow to do either, particularly the latter since you don't show us, not to coil the excess line outside because it decreases efficiency and creates oil traps in the lines, it's not at all helpful to tell us to run it up and then down inside the wall or zig-zag it inside the wall since that would require us to tear out all the drywall and insulation between those two studs to do that, meaning we'd then have to reinsulate, re-drywall, and repaint. The same goes for even running the line inside the wall at all since we can't, so the average DIY'er is going to not have the line run down inside the wall but have the line go straight through, or at a slightly downward angle to keep rain out and drainage flowing downward from inside to outside, meaning the outside hold will not be 8-feet down from the inside hole but be only a quarter or half inch down such that you can see straight through to the outside, making the excess line issue that hasn't been feasibly addressed for "dummies" even more of an issue as all of the line except the last several inches it takes to pass through the exterior wall inside and connect to the inside unit will be outside.
My minisplit is only 4.5 amp and connected it directly to an outlet and it works great no outages or anything
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.
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.
@nedjinski this would not be possible for the “DIY Models” knowingly cutting into one of these pre-filled refrigerant lines is illegal. Please call a certified and licensed person to make alterations as the refrigerant must be handled properly by a competent person.
@@luisrodriguez4308 The compressor is charged with refrigerant, not the lines. (lines may be pressurized with nitrogen). After the lines are evacuated, you release the refrigerant INTO the lines by opening the service valve).
An electrican gets in the habit of wearing 'electical resistant' gloves and keeps his hands off the steel shaft of a screwdriver.
Good thing I'm no electrician ;)
You provided the first good recommendation that I've seen on the why and how to deal with excess Line Set length. Thanks!
You're so welcome!
Best video so far on the Mr. Cool unit. I especially liked the demo of charging the lines (if that's what was being done)> Does anyone know more about doing that. I'm not sure what is going on. The gauges showed a center yellow/tube line but I don't know what it was being used for. OK... I found another video install (not the same unit) the yellow tube is for the pump. Once the check for leaks is done the pump is not needed because the system (compressor) has the refrigerant in it already. Cool... Thanks.
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!
Danger is my middle name (or dumb...hard to tell most days). Thanks for watching Jorden!
As a general rule, leave all metal jewelry & watches at home. This addresses electrical and mechanical (fingers crushed by rings) safety.
Just the tip!
lol
arrgghhh ! I have gauges and knowledge from when I was an HVAC tech back in the day .... what I DON'T have is the adapter, apparently, needed to connect said gauges to a mini-split. I just went thru this same aggravating BS trying to connect my gauges to a R134a can for cars. Nothing better than getting ready to complete an easy task to find out the industry decided they will require a special adapter that you will have to order and wait a week to show up so you can complete the job. I repeat... arrrgghh.
Lots of good tips but the one about not coiling the supply lines is great. Also, I was about to buy an open end torque wrench, I might skip that now saving $150. Thanks. Subscribed.
Young man never work without a shirt or wearing a chain on your neck 🧐
Why not? He was hot, in more than one way!
He did have a chain around his neck so he had that part covered .
LMAO! Had to get myself together after the tRex
you and me both
Good video. I used the same kind of wall mounting rack for my 18K MrCool. But I have vinyl siding and it gave no support for the condenser's mounts. 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.
Excellent video with valuable info left out of many other DIY mini-split videos!
Thought I was the only one who does electrical work in the nude haha!
It was hot as balls! Hence the need for AC!
19:37 that underarm hair was really turning me on
Great information.
“Best CZcams channel I ever made” Good one.
UNBELIEVABLE! My local Heating and Cooling company (thru Home Depot) wants $12,000 to install a $995 mini split AC unit. I thought it would be rocket science!
HAHA..."that's what she said"
Proud 5 1/2 lol
BIG Question: Appreciating Lesson while wondering about turning the blue
valve to off after the 15 minute vacuum procedure. I think you may just be measuring if
there was a vacuum leak in a gauges and guage set up middle piece with that blue
valve OFF instead of measuring potential leak in your mini split and
its' cooper lines via leaving the Blue Vale ON ??? My testing while doing this procedure today lead me to believe that Blue Valve best be left ON to test for vacuum leak in full system (and another CZcams teacher just got my same feedback). I will study harder before opening up my mini split to release its' freon to the whole setup. Liked your low pressure line test.
I have recently learned from someone else's mistake via another CZcams Lesson; that the gauge vacuum hoses have a fitting side that will open the shrader valves (You covered that point nicely). If you hook up your vacuum line backwards with no release of shrader valve at mini split fitting, you will only be putting a vacuum on the vacuum hose and gauge set only. One guy figured that out after releasing his mini splits' freon to whole system, and then he had an expensive back track lesson to get rid of moisture that he figured contaminated his freon (that shorten unit lifespan). ... Learning More All the Time !!!
Thanks, this occurred to me. I actually tested my gauges first to ensure there were no leaks. I pressurized them and let them sit for two days while monitoring the pressure.
These come with a factory charge. Why did you say there was nitrogen in the inside coil? And since you evacuated the lines and inside coil, wouldn't you need to add refrigerant to get it back to where it needs to be? I'm just confused about this...
I read that the extra pipe length is important as it will hold more refrigerant which keeps the pump running less due to more ability to cool or heat?
But still good video!
Love he’s not wearing a shirt👌🏻 and now I know how to wire a mini split, which I just ordered
That's why I needed to install the air conditioner lol
very nice work..,but I am curious about why in the A/C box you not connected the WITHE (NEUTRAL) wire and you connected on the Service Panel in the NEUTRAL BAR??
On the outdoor refrigerate piping there should be a drip loop as to allow the rain to drip away from the structure. In your setup this is the opposite.
I fixed it but never showed it on video. Good catch but no worries!
Best OCD panel I've seen in a while, kinda like ones I've installed, kudos.
Thanks man, I know that feeling. If you're doing it, you may as well do it with pride in your work! Thank you for watching!
THANK YOU for saying it is nitrogen in the indoor units for transport. I tried to contact the company and they told me it was freeon. I had no idea how I was supposed to disconnect the plug without releasing all the freeon.
You got it. Freon is in the compressor and they vac out the line set after adding nitrogen so you have nothing but an inert gas under vacuum. Sad that the company itself knows less then a monkey like me on CZcams.
You have your heat pump way to close to the wall. It should be at least 1 - 3 feet of clearance from the wall. It appears that I purchased the same bracket as you did. I also needed to purchased a 4 ft. square pipe, cut it in half and drilled holes to get the 1 ft clearance, as well as longer bolts. It added the extra 5 inches I needed. If you don't do this, it will lower the needed air flow through the unit cutting performance. My manual says 1 foot of clearance is necessary. Great video none the less.
Most mini split systems only require a min. of 12 in from a wall behind the unit, on each side and 24 in above. Wall mounting kits take that into account.
Awesome video! Just told my wife to get the Mr.Cool! I have the flare tools and vacuum gauges. Thanks for the video! Now off to find my tape measure and hole saw
Awesome! Thank you very much for watching and hope this helped. Good luck with the install. You'll be "chilling" in no time.
nice job, mr cool like mr slim. good luck down the road. i would recommend a surge protector at the main. i have changed boards
out on the condenser from incoming power spikes. those boards are not cheep.
Thanks and yes, I have a surge protector on the main panel. I have way too many electronic toys to risk it!
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
