Update: Followed your lead with the pump, and I wasn't getting a vacuum to hold. So I tried the open the low pressure allen screw a little and lo and behold, that exposed a leak at the upper 3/8 fittings. Not torqued enough. Once I tightend that, you could hear the difference in the pump sound. Getting super cold air now! The soapy water didn't show anything. Very good video. I wasn't sure, because the manual shows using the insulated tape at the indoor unit to wrap all the way to the outdoor unit. Which imnplied taking off the initial foam that comes with it. In either case, I will leave that foam on and I will wrap the whole length with the insulating tape. The manual also discusses using appropriate torque when tighening the pipe nuts. 1/4" line; 13.3 to 248 ft lbs. 3/8" line: 22.1 to 25.8 ft lbs. And applying the putty to seal the tube at the wall on the outside. I also found it easier to connect and clamp the indoor unit wiring and then just snake the rest of the wire out the tube. Also, from my safety box for power, I used flex conduit with a flex conduit plastic fitting. The drain tubing, which is the same as was on my MrCool that I'm replacing, I can tell you will not hold up for long in the TX heat in the summer. Within 2 years, it was so brittle it just fell apart. Instead I got some 3/8" acrylic tubing from Home Depot, used pointy nose pliers to stretch the end some to fit snugly on the section coming out of the inside unit, that was still sound. That stuff can take a licking. I also found the wall plate, vs the MrCool version, is very delicate. When I put the indoor unit on it, the top right finger bent out about 1/4". The Mr. Cool uses about a 2 foot lip at the top that in the middle and very sturdy. So now I have to deside to I want to take it down again and add more screws to make it more sturdy. Or just leave it as is. It's not going any where and I might just leave well enough alone. In spite of the same rating as the MrCool 12k, the Della units are a lot lighter. The outside unit is much narrower and the inside unit is lighter and slightly smaller.
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
Nowhere in the install manual did it mention it came with rubber feet. It does say 12" clearance from wall for outside. Are you just using the open space underneath for your clearance? Install manual also shows the hole cap goes inside. I guess it isn't needed outside if you use the line covers, the head unit takes care of it on outside. I think two tube caps for both sides for what they charge should be included. My pad just came in. Now if the rain would cooperate. 1800 BTU unit. Running the lines is what made me put it on the outside wall. Had enough trouble drilling a 3/8" hole for my network cable in the inside wall. Trying to fish copper pipe would not have been fun. Thanks for the heads up about the adapter for the vacuum hoses.
This is a 1st class installation video. I just wired up the power wire to the unit before I set the unit on the bracket. Then I slipped everything through the exit hole. One other thing I did was to wrap the lines with the drain line on the bottom ( the power line higher up and to the side) before I slipped it through the exit hole. Electrical tape ( in 3 places) would do it just to hold them in place. Really comprehensive install video. If you can't install this (maybe electrical from the breaker box) after watching this video you have 4 left feet, that is if you have the proper tools and common sense. You may also want to pre bend the lines BEFORE you slip on the beauty ring. That little extra wide hole opening helps in carefully bending down the copper lines. Then slip the beauty ring up and over the lines and into the wall. If you are going to install a concrete pad the outdoor unit when shipped is sitting on a waffle piece of cardboard. As it sits mark out the bolt locations with a fine tip pen pencil or marker all around the slot. Remove the unit from the cardboard waffle and place a properly sized bolt that will pass through the feet opening and push straight down ( or drill) through the waffle. Clear out where it came through on the back side. Place the waffle board on the wet (partially set concrete) and use one extra bolt to press and shake STRAIGHT down into each hole to mark the location. Take off the waffle board and set your bolts hex head down into the crete as close as you can. As the concrete sets turn over the waffle board, place it over the installed bolts and adjust the bolts if needed accordingly with the waffle still in place. Spin and shake the bolts slightly and leave sit. Once cured enough remove the waffle and your unit should slip right off over the bolts. No drilling...just a simple nut screw down. Use lock nuts with a washer and the supplied rubber vibration pads. If the bolts are a little off screw the nut on the bolt and tap the nut, not the bolt, with a hammer. Perfect quick and secure.
Great video, the only thing I would disagree with is when you said the instructions they give you are clear and easy to follow. They should just pay you for letting them link to your video. So much better, thanks.
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.
Hi Seth, Thank you so much for such an awesome video. We installed our mini split successfully....All Credit to you. Easy explanations on things, very meticulous on details, nothing to miss out, No extra fancy stuff etc. ....its such a great video for learning. You saved us at least few hundred dollars on the unit and another few on installation etc. Most importantly the learning and the confidence it brings to be independent is priceless. Like the other viewer from LA mentioned..... whenever you are in Bayarea pls let me.know....Drinks and Biriyani on me 😊. Once again....Thank you and keep rocking. Cheers!!!
So happy to have this video as a reference. I installed almost the exact unit except mine is 120V instead of 240. The only issue I had was I thought I could shorten the piping fairly easy but I understand that’s not a great idea if you don’t know how to adjust the Freon levels. Just a warning that it can cause the unit to short cycle and other issues if you shorten the pipe length without adjusting the gas. Otherwise, super awesome video and I’m so excited to work in my 20x20 garage now conditioned. The Las Vegas heat can be enough to keep you out of your garage at times.
Very Nice one. Well done! all the way from Bulgaria. And this is the reason that I've decided to do my own installation of my two additional ACs. I would have had paid someone to NOT use torque wrench on the pipes and fittings, or NOT to Vacuum pump the systems before the commissioning. They do not have the time to do it properly, unfortunately, or the money to buy correct tools. They correctly say “if you want anything done right, do it yourself.”
When I converted my car from r22 to r134 I put the system on a vacuum pump for 18 hours to boil off any moisture in the drier. 18 years and it still works fine.
Thanks so much for sharing!! Just installed our Della 18,000 btu mini split after watching your video multiple times and it is Awesome!! Thanks for going over everything so well! I did find out after I pulled a vacuum and made sure it was not leaking. It worked really well to just go ahead and disconnect the vacuum line before I let Freon into the line. It made absolutely no noise and let nothing in or out. Thanks Again!!😊
Thank you for the video but i think you should check the leaks before you vacuum the system to avoid any air or moisture going into the inside Ac unit.
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.
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.
I had to download the app twice, first one did not recognize my unit, second download I think was different and after yelling and blaspheming it recognized my 18000 unit
@sethcraftworkshop same. I'm working on making automotive videos for people trying to learn and it's very difficult to say the least. Editing is stressful
Hi, great video! One question for you. I bought a 9000btu Della split system. My shop is 12 feet' by 20feet', does the fan inside have enough power to throw tempered air the length of 20' or would you think better performance mounting the inside fan on the on the long wall and throw air the 12' direction? Hope that makes sense. just trying to figure out mount on long wall or short.
Hi, Seth it is really a good video to watch, and I enjoyed it, I have been watching all your videos about your 20 by 30 work shop, And I really liked that way you were explaining about the construction of your workshop, I really enjoyed and learned about your videos, nothing but excellent, thanks Seth.
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?
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.
Quick question for you. Is part of the black wire that runs from the condenser to the inside unit okay to be expose like that or should it be protected somehow ? Cause I know overtime with all the water and uv exposure it’s going to wear down
I am installing a 3 zone but woll only use 2 zones for now do i have to vacuum individually? And later if i want to connect the third zone do i have to vacumm that as well?
Yes, you are clearing the lines. Even if they are all connected in the compressor they are sealed off till you open the valves, and then it is to late you let air into system. I am curious how the energy efficiency works with multi zone.
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!
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 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.
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.
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.
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?
(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.
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.
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.
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.
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
@@carltierman4202 Unwritten anywhere but most of the Della 10' and 16' install kits are connected to condensers with enough refrigerant for 25'. It is when you go over 25 ' you have to calculate the additional charge needed and you also will need a bottle of either the 410a or R32 depending on which della unit you are installing, you will also need the manifold, gauges, hoses and adapters to add the charge. Every install booklet will have the wt per foot required
@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.
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.
@@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.
Your a god If you can get a 1/4" hose to hook to a 3/8" connector. Even hooking the drain line to the larger suction side would be amazing. Cross threading and not torqued are your only issues.
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.
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.
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.
@@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
OMG, you poor guys still have to put up with that crappy R410a. Would not do this without calibrated torque wrench and a nitrogen pressure test. It helps to have the indoor unit leaning 2 degrees to the right for long life draining. A $6 valve removing tool is also a good investment. Recently I learned that a thicker vacuum hose also ensures a better vacuum, a single electronic gauge takes away bottle necks.
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.
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.)
@@sethcraftworkshop we installed a della 9000 btu last week and did not vacuum pump😒😒🤦♂️🤦♂️ indoor unit know leaks 🤦♂️🤦♂️🤦♂️ can we still pull a pump on it or not ????
@@FOODONTRUCK You have probably contaminated the refrigerant which most possibly end in condenser/compressor failure. You need someone with recovery equipment who can run your refrigerant through a filter/dryer before you go any further. I don't know why DIY folks insist on doing a mini-split install without pulling a vacuum. Crap, you can purchase a vacuum pump and a set of manifold gauges for less than 100 bucks. Or if you're anywhere near Bergen County, NJ I can loan you a set. Jees.
@@askgranpa8041 Well if it leaked there is nothing to recover. 🤔But now you will need to buy freon. So the ac tech can do a nitrogen check before filling. Worst part is R410 turns acidic exposed to air. That is why compressor probably has a shorter life span now.
You would still get the same readings if you hook the suction (blue) line to vacuum pump. Although back in the 90's I had a pump that needed the reed valve removed from hose to work. So you would not get any vacuum pulled unless you removed it from the blue hose if you hooked it backwards. You could hook both sides up and vacuum from both hi and low lines at same time. Air doesn't care where it comes out.
Update: Followed your lead with the pump, and I wasn't getting a vacuum to hold. So I tried the open the low pressure allen screw a little and lo and behold, that exposed a leak at the upper 3/8 fittings. Not torqued enough. Once I tightend that, you could hear the difference in the pump sound. Getting super cold air now! The soapy water didn't show anything.

And applying the putty to seal the tube at the wall on the outside.
I also found it easier to connect and clamp the indoor unit wiring and then just snake the rest of the wire out the tube. Also, from my safety box for power, I used flex conduit with a flex conduit plastic fitting.

Thanks to biden it is now cheaper to buy a micron gauge than pay my ac guy to come out and hook one up to check for any leak.
Thank you for a detailed installation, that was worth watching a longer than usual video.
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.
Awesome! It is nice to have ac in the shop. Installing a mini split is not too bad.
you use stranded wire for the 220v? Should it be solid wire 12gauge?
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.
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.

Hi, great video! One question for you. I bought a 9000btu Della split system. My shop is 12 feet' by 20feet', does the fan inside have enough power to throw tempered air the length of 20' or would you think better performance mounting the inside fan on the
on the long wall and throw air the 12' direction? Hope that makes sense. just trying to figure out mount on long wall or short.
Hi, Seth it is really a good video to watch, and I enjoyed it, I have been watching all your videos about your 20 by 30 work shop,
And I really liked that way you were explaining about the construction of your workshop, I really enjoyed and learned about your videos, nothing but excellent, thanks Seth.
How long did it take for your unit to begin cooling after it first was installed and running?
Perfectly explained thank you.
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?

K 2 videos I’ve watched once vacuum was done they 1/4 turn bottom line for 5 seconds u did the top one does this matter?
Very well illustrated. Thanks, dude.
Thank you! I hope it helps.
You should tape the lines and drain pipe together before sending them through the hole in the wall
Ive noticed a lot of people are using micron meters during the vac these days - is there a reason why you don't?
I just followed the install manual. So far so good.
Do they come with a way to hang the exterior unit? I really don’t like how you pretty much put it in the dirt.
Yes, they make wall mounts to hang them on the wall. Says you want 4 times the weight of the compressor. So 90 lb unit, you want mount for 360lbs.
What was the gray plastic barb drain piece used for on the install?
That is for draining the outdoor unit if you have it on a wall mount.
Quick question for you. Is part of the black wire that runs from the condenser to the inside unit okay to be expose like that or should it be protected somehow ? Cause I know overtime with all the water and uv exposure it’s going to wear down
I stuffed mine under the building. However I should think covering it would be good. You are right. Sun exposure over time will break it down.
What breaker size did you use? 15 or 20 amp dual pole?
I used a 20amp.
I am installing a 3 zone but woll only use 2 zones for now do i have to vacuum individually? And later if i want to connect the third zone do i have to vacumm that as well?

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.
Mine didn't leak over 30 minutes but it did leak over 3 days
Should have done a nitrogen pressure test.
When you make the bends with the copper do you just do it by hand? Thanks.
Yes. The book shows how to hold the lines when you make the bends. This is to prevent kinking the tube.
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.
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.
What if you leave it coiled and hanging vertical?
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?
(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.
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.
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.
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.
@@jameszzhSome sites have reported that Senville builds Mr Cool and Pioneer.
The manual, you can download it from Della, says 14/2. I ran 12/2 wire.
Can you send me the link to the vacuum pump.?
Yes it should be in the video description.
Why are you using soapy water to detect a VACUUM leak?
There would be no bubbles, right?
The primary reason I use soapy water to detect a leak is because the instructions say to do so.
You’re absolutely right. Bubbles would be detected after a positive pressure test with nitrogen. Obviously a vacuum would not produce bubbles.
He opened the valve for 5 seconds, so it would have pressure in the line.
I like to make new flares, also trim lines to size, I never really liked factory flares, usually kind of ragged.
New flares are nice. I do not have the tool for that.
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
@@carltierman4202 Unwritten anywhere but most of the Della 10' and 16' install kits are connected to condensers with enough refrigerant for 25'. It is when you go over 25 ' you have to calculate the additional charge needed and you also will need a bottle of either the 410a or R32 depending on which della unit you are installing, you will also need the manifold, gauges, hoses and adapters to add the charge. Every install booklet will have the wt per foot required
I forgot to mention you will also need a special left-hand bottle adapter for the A2lL R-32 refrigerant charge.
If the vacuum doesn’t reach 30 what does that mean
29 should be fine. As long as it holds the vacuum.
On your gage lines. Do I need to remove the valve stem?
Not on this one. Because I am not adding any refrigerant there is no need to remove the valve stem.
Great video thanks
@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.
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.
@@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.
what if I mixed up the hoses and connected them wrong?
Your a god If you can get a 1/4" hose to hook to a 3/8" connector. Even hooking the drain line to the larger suction side would be amazing.
Cross threading and not torqued are your only issues.
Why do you need an adapter to hook up the low side? Will the line from the vacuum pump just hook up correctly?
Normal with mini-splits. Read up!
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.
Yes that is correct.
The same vacuum pump you linked comes with the 5/16 female to 1/2 male adapter, is it just thread size that needs adaptation or is it something more?
Great video Seth
Thank you. This unit is working well.
How long did it take to begin running cold air?
After it was installed? Almost immediately.
@@sethcraftworkshop thank you!
@@sethcraftworkshop Have you ran the disinfection mode? Was curious how long it takes.
What is the size of that hole saw?
Della recommends a 70mm hole saw.
So needle moved from -30 to right below 0. Is that an issue?
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.
@@sethcraftworkshop thank you for the reply! Yes I found the leak in the high pressure side. All good now!
Mine couldn’t reach 30 it was only able to go to -29 but didn’t go down when testing for leak
Its okay
That will be OK.
Pro work, Good stuff.
Thank you. Its nice to have this mini split in the shop!
what is the diameter of the hole in the wall?
could I connect this to a standard 110V indoor outlet? I can’t use a mini breaker outside
This particular mini split is for 240v. I believe the della unit that is 9000 btu is designed to ruin on 120v.
you need to buy a 120v VERSION. Then, you can do it.
No nitrogen test ?
I did not do a nitrogen test. Just followed the directions of the mini split.
No nitrogen bottle 😔
Thanks for the details!
Happy to help!
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
Thank you. Because of the video it took me a while to install but its not bad when not filming.
Mine is showing a P2 error message and not sure what to do. Not cooling and fan stops spinning
That error did not show up on my system. have you tried customer support?
Did you add any freon
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.
It is the same as mine, sold under Elit brand, but true is, this it TCL from China!
Seems commonplace to have a rebranded unit from the same manufacturer. So far I am pleased with the mini split.
I tried a lot to find who is the manufacturer, but failed. Thank you for this information.
@@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
Not a complete install shown, you left out the wiring at the breaker…
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.
20:35
OMG, you poor guys still have to put up with that crappy R410a. Would not do this without calibrated torque wrench and a nitrogen pressure test. It helps to have the indoor unit leaning 2 degrees to the right for long life draining. A $6 valve removing tool is also a good investment. Recently I learned that a thicker vacuum hose also ensures a better vacuum, a single electronic gauge takes away bottle necks.
Della sells a R32 version.
hurts my eyes to look at this 😪
Was it like a bug to a zapper? lol
Why? What went wrong other than bubble test.?
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.
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.)
@@sethcraftworkshop we installed a della 9000 btu last week and did not vacuum pump😒😒🤦♂️🤦♂️ indoor unit know leaks 🤦♂️🤦♂️🤦♂️ can we still pull a pump on it or not ????
@@FOODONTRUCK You have probably contaminated the refrigerant which most possibly end in condenser/compressor failure. You need someone with recovery equipment who can run your refrigerant through a filter/dryer before you go any further. I don't know why DIY folks insist on doing a mini-split install without pulling a vacuum. Crap, you can purchase a vacuum pump and a set of manifold gauges for less than 100 bucks. Or if you're anywhere near Bergen County, NJ I can loan you a set. Jees.
@@askgranpa8041 Well if it leaked there is nothing to recover. 🤔But now you will need to buy freon. So the ac tech can do a nitrogen check before filling.
Worst part is R410 turns acidic exposed to air. That is why compressor probably has a shorter life span now.
what if I connected the vacuum pump hoses wrongly?
You would still get the same readings if you hook the suction (blue) line to vacuum pump. Although back in the 90's I had a pump that needed the reed valve removed from hose to work. So you would not get any vacuum pulled unless you removed it from the blue hose if you hooked it backwards.
You could hook both sides up and vacuum from both hi and low lines at same time. Air doesn't care where it comes out.
