Already commented on part 1, but this part deserves comments too! Fantastic video! Thanks so much for taking the time that you did. It can never be "too long" LOL. I appreciate the detail. I have this same unit on the way in 2 days. I have no doubt I can get it done now. This really is one of the best install videos I've seen. Thanks again!

Why did you open the high pressure valve first? How is this different from a low pressure valve?

[@balkicroatia]

Screwing by fingers not to tight is fine. Using pliers cause overtighten and teflon seal damage.

[@natek6754]

These videos are so helpful! Thank you so much! I think I'll try this myself, so thanks for the inspiration! One question, the electrical runs through the line set hole and plugs into the inside outlet? Thank you again and have a great day!!

[@howididit]

Good morning Nate, the wire that ran through the wall was the communication wire between units. The power source for my unit is from the 110v plug. Have a wonderful day

And BTW, if you haven't tried a mosquito repellent with Lemon Eucalyptus oil, you should. It lasts longer than DEET, and it's natural.

[@brianhurd7917]

You don’t have to tighten down your gauges that much. They have rubber seals in them you actually damage from over tightening

[@howididit]

Thanks for the tip.

[@jonasros123]

You shouldn't loosen the hoses before opening the freon. Otherwise, air is sucked into the pipes again.?

[@johnking1079]

Love the spirit of this video... Would note a few things. 1. If you don't have proper EPA certification, the EPA can fine you up to $37,500/day. Anyone willing to turn you in can get a reward of up to $10,000. I got my EPA-Universal cert by taking a ~$500 class at the community collage. 2. You shouldn't use pliers on these fittings. finger tight should be sufficient. 3. EPA requires that system be leak tested down to 500 microns after evacuation. 4. After vacuum system. close off low pressure side of gauge; Then release refrigerant; Then remove gauges from fitting. If you release hose under vacuum, you'll suck in non-condensibles.

[@charlestreibley9904]

What for smoke are you blowing. Sounds like a HVAC guy that has lost a ton of $$$!

[@neo_265]

A lot of DIY mini splits use R290 as the refrigerant which is harmless to the environment and safe for DIYers. Providing you don’t ignite it.

[@buttonman1831]

I also agree those fittings do not require a channel loc. That is very poor practise to suggest using tools to tighten fittings that are meant to be hand tightened. They have a rubber seal for a reason.

[@davidhankins5708]

Thank you for the video. You didn't show your power source. You said in the beginning that you were going to plug it into a regular 110 outlet. Where did you get thecpower cord and was UT on the inside air handler or outside compressor. Thanks!

[@2109djones]

Yes. Where is it plugged in ?

[@davidhankins5708]

@@2109djones yes from air handler or the compressor unit?

[@samontiveros8777]

Did the adapter for the vacuum hose that goes to the mini split unit come with the vacuum pump or was it purchased separately ? Thanks

[@howididit]

Hello there, I purchased it separately off amazon

[@Melicoy]

Thanks

[@howididit]

Good morning, you are welcome.

[@PiNYoT123]

I noticed you left the blue valve open after turning off the pump to check for leaks. In other youtube videos, they shut this valve off after turning off the pump. Is there a difference between the 2 methods? I tend to think that your way is correct and the gauge will actually change if there is a leak compared to if the valve was turned off.

[@howididit]

I'm not sure, but the mini is still blowing cold. Thanks for watching, Have a wonderful and blessed day.

[@MEAKapc]

The gauge reads pressure behind the valve. The only thing holding this vacuum in this video was the check valve in the harbor freight vacuum pump. I would close the valve before turning the pump off. This was luck.

[@joseluissosa-kx4nj]

Yupppp she did this all wrong..n yes she was supposed to shut off the blue cknob than turn off the pump to verify the vacume held on -30.

[@akamegakill8903]

I have a question opening the valves do you need to open them after you vacuum or before and do you need to close them back I am new to this train and I see very different things so I very confused

[@howididit]

I vacuumed the unit down for about 15min, turned off the vacuum and let it sit for 20+ the opened them after the vacuum

[@sptsman79]

I just installed this unit and ran it for the first time last night. In heat mode, auto, once the unit warmed the room up to temperature, the temp. light on the indoor blower unit starts blinking. I cannot find anything in the manual that troubleshoots this. Is it normal? Thanks

[@howididit]

My unit did the same, it heated great, I just assumed (I know, I know, LOL) that was normal for it as the heat worked wonderful the couple of days it was used.

[@jacob-yq1ps]

what size was the adaptor? did it come with the vacuum and manifold kit? or did you buy it separately? thanks

[@howididit]

good morning, I purchased the pump gauges and adapter specifically for 410 freon off amazon.

[@bossn24]

Majority of mini splits these days have a 5/16" port so you'll need a 5/16" to 1/4" adapter to attach gauges

[@howididit]

Thanks for the info BosS

[@woodsmic]

When you took the vacuum hose off, didnt it pull lots of air into your line set? I've see other people charge the system before removing the hose, and lots of gas came out. Either way, I suppose your going to lose vacuum or gas..

[@howididit]

No, but a few viewers that do AC service advised to close all of the lines on the condensing unit and pump prior to removing the vacuum lines from the condensing unit. The unit cooled like a charm all summer, and is keeping things toasty warm with the little cold snap we are having.

[@daniellecarolina5066]

We’ve looked everywhere for that adapter piece . Do you have to order online?

Hello there, all valves are closed with the exception of the blue knob under the left side of the gauge.

[@stephenrucker8436]

It would have been wicked helpful to explain which of the knobs on the low/vacuum side were open. What are the two blue knobs for?

[@wadepatton2433]

that was all low side.

Blue Line disconnect after openning valves...never ever before🤦

Hi! Is it still running fine?

Hello there, yes, it is cooling perfectly.

[@hectorgonzalez7416]

Is this mini split energy efficient?

[@howididit]

Yes, it took some of the pressure off the main house central AC unit without increasing my electric bill.

[@SomeOne-vy5gv]

You are suppose to close the blue valve when your done vacuuming

[@howididit]

correct. pull the vacuum, close the gauge, and then open the ac lines to flow the freon.

[@tomatoman60]

I can’t find that brand anywhere on the web

[@howididit]

good morning, I purchased it off ebay from www.ebay.com/itm/352821716902

[@akuuab]

I'll just leave a comment for people who care. - don't use pliers, those connections should be hand-tight only - vacuum should be tested by micron gauge because it's order of magnitude more precise. this is not acceptable - no nitrogen pressure test was performed

[@howididit]

Thanks Alex for the info, and watching.

[@njphil1279]

After tightening up the fittings using a wire stripper, she says "Use the right tool for the job"

[@rick_3.50]

I called a local hvac company for a quote to just vacuum the line out. .... $2,000.00. I dont think they wanted to do it.

[@howididit]

WOW! that is crazy expensive. All the more reason to buy the pump, gauges, adapters and DIY it.

[@wadepatton2433]

Yes, they didn't want to deal with you. Call around--find a mechanic who moonlights. Auto A/C works quite the same. Vacuum, charge, release vac.

[@wadepatton2433]

I called "my guy" ahead of time when I was going to spend 1000 for unit. He said let me quote you a full install because they're not that expensive (and he wanted to use a larger unit). His quote was right at 4,000. I thanked him. I'd rather have a pair of little ones than one big one and know I can do it now for 1/4 the price of retail. First unit is on the way now!

[@jimmymonaco3004]

It's good but mine doesn't blow very cold

[@howididit]

Weird, Did you open both valves all the way after the vacuum? I did see where someone had forgotten to do this, and the unit was just an expensive fan.

[@bossn24]

Always break the vacuum with refrigerant before disconnecting attachments. 😒 Also please stop using pliers or channels to tighten stuff omg lol

[@howididit]

Thank you for the tips, and info!

[@edog8142]

@ howididit you did an amazing job, doesn't matter what you use to tighten those connections for the vacuum lines as long as they are tightened

[@TheSateef]

looks like you did this totally wrong, disconnecting the blue line before releasing the refrigerant, you lost the vacuum. people really shouldn't make video if they don't know what they are doing.

[@howididit]

Well, doggone, if I did it wrong, I am so grateful the unit didn't realize that, as it is still cooling like a charm. Thanks for watching.

[@robertmeredith3940]

You are correct. The Schrader valve leaks at disconnection, so the manufacturer's instructions say to release enough refrigerant to get a low positive pressure, then disconnect the blue line. The line set will lose a little refrigerant, but contain no air. Her procedure is wrong.

[@rpiester]

Don't follow this video. It's wrong

[@howididit]

Help me out, how is it wrong? My unit is working perfectly.

[@rpiester]

@@howididit you disconnected the blue hose from the unit before releasing refrigerant. When you did that you lost some vacuum when you disconnected from the Schrader valve on the unit. It's better to lose some of the refrigerant than to lose some vacuum. That allows in air and with it, humidity. Your unit will work ok for a while but my understanding is that the refrigerant will degrade and potentially damage windings in the compressor. I'm not an expert but I e watched dozens of similar videos. By the way, nice job on the video other than this one part of the procedure.

[@howididit]

Just a heads up, I pinned your comment to the top of the feed for other folks to read, thanks again.

[@arionmagnoli]

You never Vac down for a period of time you Vac down to 500 microns. Whatever time that is changes from unit to unit.
