It’s better to wrap the UV tape from the bottom up. If you wrap from top down it can let water in through the over laps. Think of it like shingles.

Great video. I've watched dozens of these mini split installation videos. You are the first one that used "positive pressure" from the unit before you removed the gauge lines. What a great idea!

Just an FYI, if your vacuum rises a tiny bit then stops, that's okay. Run the vacuum pump again until you're back to zero. What happens is that as you pull the vacuum, water vapor in the line will condense and then freeze. Ice will not vacuum out. But as the lineset warms up and the water evaporates (sublimates, actually), it will cause the vacuum in your line to drop. Will didn't have to deal with this because he's in a desert, but if you're in the southeast you will see it.

Just put in the Della early last week. Already had the vacuum pump so it was super cheap. I welded my own frame for an overhead side mount (roof). At 20 SEER they are super efficient and incredibly powerful. After installing the second one I can't set them under 73 or my house gets too cold. All this when temps here have'nt gone under 100F for the past two weeks. And they heat well in the winter. With my solar panels being installed next week it all came together beautifully. Thanks for inspiring me to get it all done.

Additional Consideration Idea: If the outside wall has ribbed siding, you want to make sure the hole does not go thru a rib, but stays on as flat of a surface as possible, in order to avoid an opening that is harder to seal off from bugs and water.

Great Video. I have a Pioneer unit that is about 10 years old. I did not have the HVAC tools, but I installed it all myself and had an HVAC tech friend come over to vacuum it and release the refrigerant. I've never had a problem with it and have been very pleased.

Recommend getting your EPA 608 Type II cert. This way you can buy additional refrigerant if needed and legally add in if you have a longer lineset. I studied for a day then did a remote proctored course with Esco Institute. Got my certificate same day. Only installed one mini-split in my cabin so far and needed to add a few ounces refrigerant since my line set was 35 feet and unit only holds enough for 25 ft.

Thanks so much for re-posting. I was leaving a thank you comment on the last one when it disappeared. You are a consummate professional, Will, to take one down, update it or do it over, and post again. I appreciate your honesty and all the effort you make to teach us. I'm a novice at this, so your instruction is needed. Can't say I don't wish you were my neighbor so I could offer to hire you to look over my shoulder, making sure I do it right.

I just ordered my Della and everything you recommended tonight Will . You do a tremendous public service to those of us who are handy with tools. I was quoted $3200 to install a similar unit. I may be old but i am not stupid, thanks Will.

One note of warning. The pre-loaded refrigerant is metered specifically for the length of lineset included with the kit. When cutting the lineset short make sure to refer to the manual so that you don't have too much refrigerant for the amount of lineset. A professional HVAC technician can adjust your refrigerant if needed.

You watched a lot of videos and did a lot of research to make this install. That UV resistant white sheathing is only rated for 90 days UV resistance. It’s never meant to stay exposed to the atmosphere directly to the sun for long-term. . Good job you have been improving over the years, looking more professional, and getting more steps and procedures correct I’ve been watching you since you lived in your van. From your very first videos.

Glad to see this re-posted, Will, with all the technical info on the refrigerant lines brought up to spec. Looks good.

Put in my first Pioneer 7 years ago DIY style, I now have 3 + 1 multi split. Because these are so efficient the solar system I just installed was very affordable and the overall system, Mini Splits + Solar, works great! Power company is going to think I'm on long term vacation.

Great tips! More tips for the viewers: Get an "inverter type" / variable speed compressor. This is more efficient than "all on, all off" type... Get a heat pump if you also want to run it in reverse and pump heat inside. If you do, you will also need a drain line on the outdoor unit. There is also a service adapter valve kit that allows you to connect your pressure gauge behind a valve so you can turn off the valve before removing the gauge set. Basically a valve for your lines. Wear a hat if you work in the full midday sun... I usually discard the stock insulation and replace it with better and thicker pipe insulation, slid on prior to install. If you need to run longer lines, the manual will tell you how much more refrigerant to add, if so, and what the max run and heights are...

Great video Will. Been in the HVAC industry since 94 and started by company in 2010 . We do about 20-30 of these a year . The only thing I’ll say is getting parts for these off brand units is very difficult as well as finding a licensed legit contractor to work on customer provided equipment . There will be warranty issues as well for customer installed equipment . Kudos to you taking this on yourself .

Great video. I am curious about the power connection to the outside unit though. In the video, it appears that you just ran an extension cord through the wall to power it. If so, there are several problems with this that some DIY people might not be aware of. The first is that the wire is unprotected and extension cords are only rated for temporary use. They are not designed to be exposed to the elements for long periods of time and the jacket will break down on it from UV exposure over time. A "up to code" installation would use THHN wire in watertight conduit. The second concern is that electrical code requires an accessible manual disconnect within sight of the outdoor unit and you don't have that. Finally, if it really is being powered from an extension cord wire, chances are that it is not on a dedicated circuit breaker as code requires. If it is, then you have another problem from running the extension cord wire into the breaker box. None of this is meant to detract from the usefulness of the video. You covered a lot of things that many similar videos miss and did it well...I just think you need to reexamine the power connection to make it safe long-term.

3 things: 1) Thank you for the bonus video. Immensely helpful 2) TY for saying look at the blue lineset to see the mist 3) I could totally tell you were under the weather bc your voice was off. (feel better)

A very informative and straight forward video. Easy to understand even for someone who is not all that handy as a DIYer and to tell the truth a nice video for even a Professional to give them a refresher if they haven't used a vacuum pump in a long while. . Thanks again Will. I always enjoy your videos. straight forward and no BS

Easiest way to mount the inside unit is to tape the template to your wall, drill the anchors holes and the 2.5 inch hole, then remove the template and install the bracket. That way you don't need to measure and you'll have a perfect hole every time.

Thanks for this instructional hands on, verbal, & precise instructions!

Wow, I am putting in a Pioneer in a couple of weeks and I can already tell how incredibly useful this video will be. Thank you, Will!

You provide some really great step-by-step instructions your videos are awesome. I've learned a lot that's so much on the heat and air I'm already up on that but pretty much everything else you've done is top-notch

Will, thank you for taking the time to research the different products & tools. Keep up the good work.

You're like a magician that reveals his tricks! This is the perfect video that I needed for my off grid cabin. I was putting off the mini split until now. I'm ordering all the stuff you recommend immediately...through your affiliate links of course!

Great install video. The crow's feet attachments for using existing torque wrenches are a really nice touch.

Love your passion for helping people. Have followed since...... forever! You've never changed! Thank you for helping so many and doing it so selflessly and with great joy. It's very appreciated in these times for sure. Stay well Will!!

Awesome video! You have de-mystified mini-split installation. Clear steps, closeups, tool list, thanks, Will.

Great that your Demonstrating the installation procedure for a mini split, or standard air conditioner for that matter to the do-it-your selfer. I particularly like that you're pointing out the savings between the units.

Good video however you should pull and hold the vacuum for longer, say 30/60. It is also advisable to secure the compressor/condenser prior to installing the the lines thereby minimising stress on connections

This was a perfect breakdown of how to do it. Thank you for demystifying things regarding the lines for me.

Awesome video, couple comments, and suggestions. 1. The big hole for the lines doesn't need to be in the same spot as the template. Move it horizontally to fit your need. I put mine in the middle of the wall mount. 2. I'd run the vacuum pump for at least an hour to remove moisture. 3. If you need to buy an adapter, get one with a valve. That way, you can remove it without losing refrigerant. 4. Check for leaks in the system with it on heat mode. The system will see the highest pressure during heat mode, over 400 psi. 5. Putting sealant on the flare connectors is good practice.

Nice video. Brought back memories of doing this stuff with my dad who was in HVAC for 40 years 😁

Great video teacher, I love you for your patience and ability to teach, I have followed you for a year and with that I have learned and took my family off grid and now you arming me with knowledge to replace my auxiliary window A/C to this system!!!!! Thank you Will

Love this, may do my own mini-split next year, I even have a spare vacuum pump from my freeze dryer, the Harvest Right Premier pump...

Your channel is my favorite when it comes to diy electrical. You’re a great teacher. Thanks!

Great video, Will. This Vegas heat is killing me! 🔥

One thing he didn't explain when tightening the copper fittings, but which I think he did properly (it was hard to tell) is that the crow foot wrench goes onto the torque wrench at a 90 degree angle, not straight out like you would think. Otherwise you would get an incorrect reading due to the extra length and leverage.

I've had 2 pioneer minisplits now for over several years and love them. The first one went on the bumber of my work van and I bought a new one when I got my box truck. They do a super job, I run them off of solar and lifepo4 and it's been great!

Great job dude. I too have done this myself. You did a great job explaining everything 👍👍

Definitely the best mini split install I've seen. Short and to the point. Nice job Will.

Thx Will, this video was invaluable. I am installing my first mini split next week!

Thanks will. You’re the expert I keep watching!

Thank you Will for this easy to follow video. Just installed mine in our house in Aguascalientes, Mexico. Low humidity here but the daytime high just broke 90.

Yes!!!! Thanks Will for doing one of these

Those line set covers are nice to have for long term service use. Protects from extreme heat like you’re at +extreme weather including rain\snow. Line set should be off ground anchor to home or if you don’t want to do that I guess you could use some 1-1/2” pieces, a unistrut/super strut with clamps and anchor the strut straight to the concrete with anchor, then use clamps for line set. That would make this DIY a very professional looking install, thank you for sharing and all you do.

Great job explaining the process. I did the Mr. Cool a few years back for a friend for his garage and it installed very quickly. Our codes required an outdoor disconnect so I installed that along with a concrete slab and secured the unit to the slab with tap cons. When I go and do mine, I'll go with the Pioneer or Della and save some coin.

Thanks for the tutorial Will

Excellent job! This was very helpful. Thank you!!

Another relevant video, I bought something similar, wired and plumbed it all myself and got an Ac guy to purge the lines for a $100. Whole project cost me 1/3 of normal price. I didn't bother with the torque wrench, I just did it up tight and I imagine it would take a very strong ape to over tighten it :) Great video, cooling is no longer a luxury in a brutal heat wave.

Excellent video. What I like is you explain and show in detail every single step.

That was a really good, clear, concise, video.

Excellent job Will, Easy to follow along tutorial.

Will, a great idea for a video would be how to backup/pump down these units for maintenance or moving them. I just learned this is even possible, and there’s not many videos on it.

I think I'm going to order a Della for my skoolie... Thanks for showing how easy this is!

Will, Thanks to you I'm looking to ask Santa for one of these this year, so I can install it in my off-gride solar-powered workshop (also thanks to you). Cheers my friend.

Will, not to be picky, but please show that craw-foot extensions on torque wrenches need to be 90 degree angled to the wrench to cancel the additional length imparted by the craw foot. This will give you accurate torque.

These are great videos, because I’m seriously interested in replacing my HVAC system with several of these units. Thank you for these mini-split videos. Oh, I think that long sleeve sunburn comment was directed at me! You’re still wearing black though. 😊

Hello from Sydney Australia. Thank you for demonstrating how to vacuum the lines before the charging for refrigerant. *Vacuum pump *Set of HVAC gauges *Flairing tool 🌏🇭🇲

No idea why we watched this start to finish but it was super captivating and interesting! Now back to RV specific content for us! haha

Thanks Will. Was about to order another unit, but will check out the Della...

You're the man Will. Good stuff

Love your video's Will, you make it look so easy.

Heck yea Will these Minis are so easy. I hooked up one in my garage a few weeks ago. I have it running on my off grid solar too so getting some daily use out of it now. The one I got was a blueridge but they are all just about exact copy's and also 800$ Thanks for another great installation video! Casey

Really good tutorial Will!

You are an excellent instructor. As an HVAC tech I kind of wish you didn't help people to do my job, but you did a great job!

Live your videos Will. Keep em coming bro!!

Excellent video!!! Very well explained in detail, simple to follow instructions. Well done!

I can’t wait to watch! I’ve been wanting to try this myself!!! 🎉 :)😊

Really great video Will. You really were busy.😅 I liked the addition to the end of the video bonus clip. Great work.

Those are manufactured by Midea. Like most Chinese manufactured devices they all use similar components, just different revisions. If you ever question who the manufacture is do a reverse image search of the remote / thermostat. Once you have that info finding parts is a lot simpler. Most of those line sets have terrible factory flares. I would recommend reflaring all of them when doing an install. Eccentric flaring tools are pretty much mandatory to use to get a leak free seal. A lot of people will coil the extra line set behind the unit, this is bad for two reasons. One it serves as a oil trap preventing any oil to get back to the condenser. Two it can block airflow through the condenser. The install in the video was very clean. 👍

I ordered one of those in Feb of 2014. IT"S BEEN AWESOME. I spent about $700 on it, and I'm in an office I built in my garage cooled by that right now. It had to have the capacitor replaced 2 years ago. I bought the vacuum pump, but chickened out and paid a pro to draw the vacuum. He told me, that a common issue is that consumer grade vacuum pumps can't draw as low a vacuum as the pro equipment can. Get a good one.

Will. With reference to your step, opening up the lower valve just a 1/4 turn for 5 secs to bring positive pressure (gauge reading from -30 to 0) before removing the adapter from the port...May work on that brand that you're servicing, but on my Senville mini split, being very careful and doing that(I am a retired Master Electrician), the pressure immediately went to 15 psi) and I was then unable to remove the adapter without purging all the refrigerant. Everything you outlined worked fine but for the Senville unit, folks should skip that 1/4 turn step and just slowly remove the adapter letting pressure out. FYI...Paul

I’m in the middle of getting a split mini and pioneer was one of the firsts I looked at but after doing more research a Mitsubishi or Fujitsu is the way to go for long term reliability

Great video, im thinking about installing one in my storage container work shop.

Great video. Thanks. I think the trimming of the line set is important to improve system efficiency, but if unable, it's worth mentioning that the coils should be laid flat, not set vertical. Vertical coils create low spot traps in every loop which will collect oil. Trapped oil means less oil for your compressor.

All this talk about studs and drilling holes has got me excited... For mini split heat pump installations

Best UKposts teacher ever!!

Thank you, Will for uploading... After watching lots of your Inverter & Battery Videos, I cant pass on your mini split video. Like always, you make it look easy.. I learn a lot from your vids. Godbless you

You are great at what you do! Thank you for the great content :)

Thanks Will for such a great video, it really helped me to get the unit going.

Thanks this was great info to help me understand how to install my new Senville minisplit. In December? yeah some of these do heating and cooling!

Great simple instructions!

Awesome videov! Easy to follow!! I was looking for a multi zone also 👍🏾😎

Awesome video tutorial. I have the exact same unit. I am also impressed that you are wearing all black! Well done! Get well soon.

LOVE this! Create tutorial Will!

great video bro, very helpful and informative

This is your best video ever

always glad to watch your videos….. my pioneer will arrive in a few days….. I had first ordered the della, then got nervous because it uses a gas that is no longer being used much in the US. and by some of the comments I think maybe the copper tubing is thinner……. anyway, for me the pioneer is 170 plus more…. my big deal is it will be mounted on a curved cinder block wall…. I will first mount a 2x10.. I have bought and borrowed everything i need… now just to wait a few more days for Fedex

Nice presentation. Very informative!

I've done 3 of these. The first one leaked after 5 years. I made sure to use Nylog Blue on the last two to help prevent leaks.

Thanks for the instructional video. What about the noise level of the outdoor unit?

Thank you so much for your explanation about mini split install I installed my own mini split hopefully I got it🙏🙏🙏🙏

What an excellent tutorial! Thank you!

Hey Will! Read this before installing my Della 18K/240v mini-split. Mounted it 8' inside house so I ordered the pioneer 16' lineset and cable... worked perfect. Had the vacuum pump and gauges (for auto). Had to order the adapter (Amazon delivered in two days). Della only put in a 3 wire power cable and 8' lines, but the 16' lineset came with a 4 wire power cable - perfect. Ended up costing the same as the unit with the 16' set. Did exactly what you said and it worked, and no leaks! I am trying to use my 48v golf cart for a power backup (eventually getting solar - looking at 400 watt panels) What is the best battery and controller/inverter?

Thanks for the Video Will, Good content.

Excellent presentation. Thank you very much.

Nice job. I'd like to do this in my garage. Just a note: Those pressure gages from HF are sized for R134. The gages do read high enough for R410 while running, but barely. It will definitely peg the low side gage when off. If using just as a vacuum gage, it's probably ok. Or use the high side to check positive pressures.

You are awesome. Such an amazing wealth of knowledge, thank you!

Nicely done!!!
