You did an excellent job of showing everything and clearly explaining. I started my install today.
I hope your install goes well. Thank you for watching..
This video helped a great deal in my installation of one of these units this past weekend. In all of the videos I've seen of the installs, the hole saw attachment, a nice cardboard template and the hex key were included and the wires on head unit to condenser power line were numbered/labeled. None of that was the case for me. The manual included in the boxes is... adequate. Make sure that you can easily refer to this video. I already owned the appropriate hole saw but since I was at my best friend's house, 117 miles from mine, I now own two 2.5" hole saws. There was nothing in the manual specifying how the unlabeled wires on the power cord should be hooked up in the head unit or condenser. I am eternally grateful to Seth that he showed and narrated "Red wire goes to #2..." Good luck, be careful.
Vertical loops in the refrigerant lines will trap compressor oil. Oil will not return to the compressor. Compressor will fail for lack of lubrication. Replaced 3 DIY installs so far with less than a season of operation. Use shorter line sets.
Could you lay the loops horizontally?
YES so oil can travel down hill towards compressor. @@mrbigstuffbsa
Would even just one loop cause that issue as well?
@@gt5193 Yes. I wouldn't trust it. Oil could trap and slug the compressor with liquid.
Yup because all of the coil outside is acting like a txv valve
Just wanted to say Thanks for posting this video - used it to complete my own install, working like a charm. (Used plastic gutter as the outside molding, worked perfectly)
Nice! Thank you for watching and the feedback. A plastic gutter cover is a great idea!
Thank you for posting this! VERY HELPFUL!!
Happy to help. These are not too bad to install.
That was hands down the best Mr Cool installation video I've seen. Thank you!
Thank you. I was going for easy to follow. Nice to hear that it was helpful.
Dude you did well! Great video shared with my neighbor looks like the way to go. Thanks for making the video.
Thank you. This install went well. Makes an exterior office space comfortable in the cold and heat.
Thank you... I'm comfortable with everything...I made a call to my local certified master electrician for the wiring part...which wasn't too expensive. So this will be done and then my shed will have HVAC...😊😊😊
You did an awesome job sir , thank you so much. You are a great teacher.
Thank you. Very nice to have a mini split on these 85 degree summer days.
I've been contemplating installing a mini split, replacing a swamp cooler setup that I have on an upper floor on my home. I have an HVAC system set up in my home, and I also have a zoned gas hot water boiler set up as well and a pellet stove on three levels. But my home doesn't have an open concept, so heating and cooling is usually irregular and not consistent. And it's wasteful heating and cooling areas that are not always occupied. Having minispits to control the environment to a particular area seems more cost effective than running the whole house HVAC or the boiler system. I'm looking to install an 18k btu dual split unit for my upstairs family room and downstairs weight room. I've watched a few installation videos on various sizes and brands of DIY minisplits. I've gotten a lot of tips and ideas from watching them. I enjoyed your video and your tutorial. Nice job..😎
Three stories and a pellet stove? You must be a fellow Yankee up here in the far north! Salutations!
Detailed explanation
Keep the good work going
Thank you. This unit has worked well.
Great detailed video. Never use a adjustable wrench that has a loose grip on it. If that jaw has any play in it you will end up rounding that brass nut Up to seventy plus percent of leaks come from not having the recommended torque.
Those wrenches were all I had for this install. I just installed another unit this past week and used crescent wrenches.
Best video I've seen on step by step to install! Thank you!
Thank you. These diy models install quickly without too much trouble.
Very good demonstration loved it
Thank you for watching. happy to help.
Well done on both the install and the step-by-step vid.
Thank you. This install has performed well.
I want one so bad. Thank you for showing me.
This unit installs quickly and has worked very well for several months. Thank you for watching.
Great video man, thanks!
Thanks for watching.
Excellent video Seth 👍.
Thank you.
Nice work!
Thank you. It was a nice install.
Great video my man
Thank you. The install is not too bad.
Good presentation for the install, the only thing you need is an adjustable wrench or two.
Yes sadly I did not bring those the day I installed. (This build was over an hour from my home)
I am in the process installing my 36k as we speak. On page 27 of my manual it absolutely states that the excess coils of lineset must be kept horizontal
Thank you for that information. The homeowner did lay the extra pipes down and put a little decorative lattice around it.
Nice job helpd me a lot thanks
Nice! Happy to help.
Great job. Would also like to see how all those wires/hoses were "tidied up". That would be useful
True. I plan on installing another system soon and can make it look cleaner.
I saw another video of someone who built something that looked like a wood pallet (only prettier) and put it behind the unit, and put the line set/hoses/wires behind the pallet. Looked quite nice.
Luckily for me I am installing this through an attic and can leave the extra line up inside instead of outside.
That will be nice. Keep those out of the weather.
Quick and efficient!
Thank you. I am now a fan of mini splits.
Minisplit install looks straight forward, I'd just be concerned about rain infiltration where the lines come through the wall. You'll have give us a follow up about how the lines were made tidy and sealed up for the weather. Thanks for sharing this.
Ah yes spray foam insulation was put in that hole and silicone around the plastic sleeve.
Some mini splits comes pre charged, seems to be easy installation. Thanks!
@@fpafdc70 From my research the pre-charged systems cost extra for the ease of install. The downside is the all the extra line that cannot be cut out of the install as this will "release the charge". I have seen other videos that suggest the coils should be coiled horizontal and not left vertical. I think the homeowner was going to clean up the install so maybe they will find a way to coil this correctly.
Fantastic video. Super helpful!
Great. I am happy to hear that this install was helpful.
thanks for the install some videos show to vacuum the lines is it necessary
The DIY model of the Mr Cool has precharged lines that don't need a vacuum.
Thank you!
Thank you for watching.
Good DIY video boss,,thanks
Thank you. This unit has been great.
Pretty good video n have a good Day
Thank you.
Thanks 😊
I am no new comer to Mr. Cool DIY, as I own 3. Here are some recommendations.
It's good to raise the outdoor unit, even just an inch or two, to avoid junk piling up under and around the unit. They sell cheap set of rubber feet meant for just this. Of course, you can spend more and get a nice raised perch with a little roof, too. You can do this post-installation, because it's just an inch or so movement.
Foam covering any lineset left out to the elements will degrade. At minimum, wrap them all with vinyl tape or something. It'd been better to pre-plan and put them in a protected space, but it's too late now. Yes, they say you can disconnect and reconnect once without losing too much refrigerant or causing new issues, but I wouldn't do that.
Great tips. Thank you. My next install is a 2 zone unit. I will be sure to use the rubber spacer feet. This kit came with tape to put on the lines.
You definitely can disconnect and reconnect. You just have to shut the valves on the condenser. I didn't hear any escape (had to replace a condenser under warranty). The instructions were literally to disconnect and reconnect.
Does the wall mount require to be installed up above by the ceiling or can it be installed like a motel style cooler
Nicely video thanks for the clear instructions.
I did almost exactly what you did but for some reason my outside compressor is not kicking on with that i am not getting any cool air am i missing something?
I am not sure why the outdoor unit would not be turning on. This system worked right away when the power was turned on.
did you figure out the issue?
Looks good!
But how does it do in 8' of snow?
Do I need to build a little house for it with louvered vents?
Not sure about heavy snow. This area only gets a few inches. Covering the unit would be fine I imagine.
Me gustaría nos mostrarás una unidad para conectar varios split evaporador y algunas recomendaciones..shalom
Thanks, brother. Now is my turn. I'm going to follow your steps.
Thanks
Thank you for watching.
Awesome video. Only thing I'll change it I end up doing a diy is I'll have to hang mine off the side of my house. I live in Canada so it'd be buried in the winter if I don't
Seems like many people mount them on the wall. That is a good option especially for high snow areas.
@@sethcraftworkshopit also has the added benefit (maybe, depending on where the compressor is located) of only needing 6"of rear clearance instead of 12" when it's wall mounted
@@robbie6625 that's a good point. I am installing one that will be ground-installed. but if its attached to the outside wall and that only needs to have 6 inches of clearance why can't the ground installation be the same 6 inches? what is the difference? (I'm just curious if i can install my outside unit a bit closer to the house).
Thanks for the video very helpful. How long did it for you to complete?
Its hard to judge the time because I was filming. But it was all done in 4 hours with video. So It can be installed within 3 hours for sure.
Any tips for finding your top plate or studs. I have tried using several stud finders, and they don't work very well. Even highly rated stud finders work poorly.
Good video but the connectors used for the wiring are for indoor use only! I believe you can shorten the electrical lines that come with the unit so you do not have all that excess wiring bunched up around the unit.
What kind of plug voltage do you plug into?
Dunning Kruger Effect video advice. The compressor often fails with a long vertical coil restricting oil getting to the compressor. Any gas pipe coil should be laid horizontal, but it's best to be cut short to match correct length and professionally flanged copper pipe ends and drench fittings with a spray bottle detergent mix for a better leak test for bubbles.
Mr. Cool states in the manual to lay the excess line sets down horizontally, not vertical , to avoid an oil trap.
Thank you. I will keep that in mind as I install another unit in the future!
Always connect your power wire last even if your breaker is off more safe
thanks for the explanation, but what about vacuum on lines before releasing the gas?
This is a mrcool DIY. In a normal mini split the copper lines are shipped empty and a vacuum needs to be pulled. In the Mr. Cool DIY the copper lines are shipped full with valve ends. No vacuum is needed on this unit. I have a Della mini split video coming out soon where I do vacuum the lines.
Nice work! Was this install in a very cold or very hot location? Is the 10 x 12 shed uninsulated?
I feel the 12K btu is too big for this size building. If location gets snow and freezing weather it
would be advisable to have mounted outdoor unit above ground level because of condensate
and possible snow blocking fan.
This location does not get very hot or much snow. Summer might see 90 degree on the hottest day. As for cold the lowest temp is around 10 degrees.
The 10x12 is fully insulated as a detached office.
@@sethcraftworkshop Thanks for the reply. I installed the same unit in my 450 sq/ft insulated garage
in Michigan. I don't run it all the time, just when the weather is bad and I need to work out there. The end user will be blown away how well it works and how quiet they are.
Hello, thanks a lot for the video , I need desperate help. I purchased air handler and outdoor unit in 2 events even the models a matching my AC lines are different in terms of connector sizes , indoor unit has small like( 1/4 male and like 1/2 male connectors) and line and outdoor unit matching larger connectors like 3/4 or so , I cannot locate what size connectors they use except 3/8 and 5/8 but that probably the line diameter ? does anyone sells adapters ? My guess they change the line sizes in recent production?
Hi Seth, great video. Am about to tackle a 36k two zone unit. You didn't extend precharged lines so not sure if you can answer this question. I am trying to center my outside unit to extend to two zones without being short and while trying to measure accurately, am trying to understand the true length. If the 25 ft lines are truly 25 feet, it appear I have a few more feet added from the indoor unit attached lines that come through the indoor/outdoor hole? So maybe 28 feet total possible with the 25 foot line set? Thanks in advance.
That is a good question. One that I don't have an answer for. The indoor unit does have a few feet but I don't know if that means the other line is shorter or if that adds extra.
@@sethcraftworkshopThanks for the reply. I just received the set. Will let you know so others can have the knowledge.
Nice video! Only thing I like to comment on is that excess line set should be coiled horizontally to avoid oil pooling? At least that's what I heard from other DIY mini split videos.
The coil is just so long. I can suggest that to the homeowner and see if he wants to bend that sideways. Too bad mr cool does not sell a shorter line kit.
They do sell a 16’ line but it can not be substituted since all units are factory packed with the 25’ line.
I've heard so many people say this, but haven't seen anyone running into problems with these Mini-Split units, so take it for what it is, I guess.
Actually they say the opposite. Coil vertically to avoid oil pooling. I don't quite understand but I guess the oil is suspended in the refrigerant and the horizontal coil makes it fall out of suspension or something...
According to the MrCool manual: "Keep excess refrigerant hose coiled. Wrap with protective tape and store behind the condenser in a horizontal position (flat with the ground)."
What wire do I use for a 5kW samsung mini split
my unit's lines and power is coming through a wall that enters basically a mud room/breezway. I then have to take a 90 degree turn and go through another wall to get them outside. A couple questions. Does the line have to remain lower than the air exchange? Can I run the coolant lines through a long sweep PVC elbow to protect them? Obviously when the lines are packed in the back of the air handler it is expected that we bend to the left to straighten them to get through the wall but can the go further to the left? Just how forgiving are these things?
The reason the lines go down the full distance outside is so the drain line will pass water out. Otherwise it would pool up and could grow stuff In the line. As for the pvc sweep that should be fine. The lines are copper and can be bent a little. Just be very careful not to over bend and cause a leak.
Great video & very helpful! But I found you didn’t install an ac disconnect box. Does it mean it’s not needed? I just ordered a Mr. Cool mini split as same as yours. Thanks!
Rhanks for watching! The main panel connected to the building has a breaker dedicated to this mini split. That should be sufficient to cut power if need be.
@SethCraft Workshop depending on state and county, some require an ac disconnect to be between the breaker And the sub breaker/ main breaker box.
@@Kilianshaw The small sub panel that he installed the breaker in is considered a proper disconnect since it is within sight of the unit.
Is it recommended to use 10/2 over 12/2 wire by chance? Is it recommended per Mr. Cool installation instructions? Great video!
12/2 awg can handle 20 amps. That is plenty to handle this mini split. 10/2awg is a bit overkill.
So even though it's not code I'm thinking a 12-gauge pigtail plug into the outlet would work?
If you could go 10 awg I would. But if your wire from the outlet is only 12 awg than that will be fine. You will want to install a box to hold that pigtail. (I am no electrician)
I see you didn't install an a/c disconnect box. I will install my system like you did under a breaker box. I guessing you don't need a disconnect since the breaker is just above it to kill the power when needed. I'm sure every state's codes are different. I'm in Florida. Thanks for any feedback. Craig
For this install, we did not use a quick disconnect box. Just used the breaker as the disconnect. There's certainly nothing wrong with adding that quick disconnect. But it seemed a bit redundant in this situation.
Hi there, Did you feed the 10 wire into a 1/2'' flexible conduit? I was trying to use 3/4" conduit but the cover on the outdoor unit accepts 1/2'' inch only unless a bigger hole is made which it seems kind a hard to make a clean whole since there is not pre made Knockouts. Any input on this? Thanks for the great video!
Yes, I did press the romax cable into the half inch conduit. I recommend that you use 10awg thhn wire. This threaded wire is easier to flex into conduit.
I used a 3/4" liquid tight NM conduit and had the same trouble with the too small 1/2" hole int the cover. Work around I used was a 3/4" LB short aluminum conduit body. I put a, 3/4"-1/2" metal reducing bushing into the conduit body and attached that to the cover from the inside with a 1/2" metal conduit nipple.
I'm about to order this exact mini split. I'm hiring an electrician to run 220 to my shop, but will it work on a 115? Or should I continue to have him install the 220 for this?
This unit is 115v - 120v but you can install a 120v breaker in a 240v panel and that will work.
The outdoor breaker, was that a gfci breaker as the unit is outside ?
Since you used #10 wire im assuming the breaker is a 30amp?
gfci is not required unless the equipment is 80 Amps or higher
There is a gfci in the house. This mini split allows several breaker sizes. I forget what size was used here.
Unit determines the breaker size, not the wire.
I have an older brick house. Is it possible to run the lines through the top of a window rather than drilling through the brick? And thank you for this easy to follow and understand video. I was hesitant with these with most needing to have some evac and charge the lines. Still hesitant on the electrical part, I hate messing with electricity even though I know it's easy. Plus I already have a central heat/ac unit set up. It went out few years ago, 2200. for the part, 4000. to replace.
Hire a pro. Your sound scared
Did you manage to run it through the window?
You have to do this is every single room
Did the rubber pads come with the unit by chance?
Yes they sure did.
DOES EACH ROOM IN THE HOUSE NEEDS A SEPARATE SYSTEM; IF NOT HOW DO YOU CINNECT OTHER ROOMS TO A SINGLE UNIT?
This is a single zone mini split. You can get multi zone. Theose have a single outdoor unit and multiple inside units.
Are there any negatives to the extra length of lines being coiled up?
They can get in the way. Also more line to be effected by temperature.
How long is that cord with the wires inside at 10:27 in? I’m about to install the same exact unit in my shop and the inside wall unit is on another wall than the outside unit. Probably about 10-15 feet away. I’m hoping it reaches.
I don't remember the length but at least 15 feet. It was plenty long.
@@sethcraftworkshop Thank you for the quick response!
I read online a mini split is suppose to have a quick disconnect switch kit to power exterior condenser. Why didn’t you use one?
The disconnect is 5 feet from the unit.
Hi. Great Video. I have a small 1.5 car garage (~400 sq ft) I'd love to cool. Can you recommend a unit that is super-easy to install that runs on a 110 v AC outlet (instead of being hard-wired)? My budget is $1500.00 but I'd love to be closer to $1000.00 or less.
I'm installing this same unit but when I attached the air handler to the mounting plate I don't think one side locked in correctly. How the heck do you get it to let go to try again?
That happened to us as well. Sadly I do not remember how we got the one side back off the wall.
Do you know if it really exists a mrcool ac with a outlet plug if my house does not have a breaker thingy outside
Technically you could place a plug on the end of the 120v power wire seen feeding this Mr cool. But I believe it's required to have an exterior breaker by code. Installing a small outdoor breaker box is not difficult.
Great video! I installed the same unit but the outdoor unit isn’t turning on. I checked the voltage and I’m getting 120V in the outdoor unit but the unit isn’t turning on, however the indoor unit is. Any thoughts?
Check your breakers. Is something off or tripped?
Isn't it supposed to be 220 volts?
@@davidmaschak528 The Mrcool 12k units are 120v.
If you have multiple systems you may have the communication wires crossed. Like you might have the wire for connection a going to connection b and vice versa. Also could be low refrigerant charge so it’s just blowing fan i would imagine
Hey man, nice work…could u have used 12g instead of the 10g from disconnect to the unit? Helping a friend install a Hessaire 12,000btu - 115v unit and having difficulty getting the 10g whip to fit into the unit, thanks
Yes 12awg is rated at 20 amps. You will be fine with 12awg.
Yes
great installation video but 20 amp circuit breaker is probably not to code should be 25 amps with #10 wire to panel. Did to review with an electrician?
The 20 amp breaker was installed based on the recommended amperage rating in the Mr. Cool install guide. The install was not inspected by an electrician. It should not have to being a DIY model. (Although I can see the benefit of that)
nice job! I hate to say it though... this feels like... 50% DIY 50% should hire an electrician haha
I'd have to agree right out of the box It was a little bit daunting but once I got into it It really wasn't that bad. Not really sure what would happen if a leak was found?
Most condensers come precharged... You still have to vacuum the evap and lines... My question is what about the air you introduced into the line when you made the connections??
For this install I just followed the directions. It does not show any place that needs to be vacuumed. Mr. Cool asked to use clips from the video in ads so they also did not mention anything about pulling a vacuum.
@@sethcraftworkshop thanks...
why did you use 10ga. for a 20 amp circuit? Also, you should be using THHN in that conduit.
Good point about the THHN. I will be sure to use that in my next install. The manual gave awg sizes and so we went with 10awg.
Good Job 👍so this unit didn't need do Vacuum ? Thanks
Correct the DIY version of the mini split does not need a vacuum.
@@sethcraftworkshop thanks ✌
What electric wire size does that 12k unit require? I’m thinking about getting the 12k or possibly the 18k unit if it only uses 12/2 wire
The instructions say 12/2 is the "minimum" for a 115V 12K unit. Also they say you can use a 20A breaker, typically also implies 12 gauge wire is OK. I used 10 gauge because my wire run was like 40' from the panel, I had room and money for it, and overkill was worth the peace of mind.
@@davidstewart1153 nice! 12/2 should work then for my garage where the wire is no more than 20’
No ablo inglés pero aprendí todo de memoria grasias
No hablo inglés, gracias. 😂
Would the 12000 btu work with a 288ft sq tiny house with high cathedral ceiling?
The 12000 would actually be too much for a small place like that. Or it would be very fast to heat and cool. The 9000 would be good too.
Could you of used 12/2 instead of 10/2 wire? I am going to install one of these and i already have a roll of 12/2 from a previous project ...
Yes, you can.
That coil of refrigeration lines stay like that ? Were those lines too long or what ?
The diy mr cool only has a set line length. It would be nice if they could offer a diy kit with other length options.
Can this be wired directly to the main circuit breaker box or does it need to have a separate box that attaches to the main box?
The mini split is supposed to have a disconnect close to the outdoor unit. That is why the separate box is there.
@@sethcraftworkshopdo you have a video showing how to add an ac disconnect?
My question is I know they have a decent warranty how ever…. Is that warranty void if you do it yourself vs having a license contractor do it ? I’ve heard it’s in the small print.
That is an interesting question. I did not read the fine print. They probably do get you with some things. Like if you wire the unit yourself vs having that done by an electrician.
On the website for the diy unit the linked warranty does exclude mini-split systems not installed by a licensed hvac contractor but specifically and clearly states that it does not apply to the diy product line.
So assume a concrete slab is required? Also what if your house is made with brick, not wood?
The instruction booklet indicates a concrete slab. All the how to that I've seen have also used a concrete slab.
You can get masonry bits to go through a brick wall. It would be quite a challenge.
There's also an available wall mount bracket to keep it off the ground. Masonry wall will require a 2.5" -3" core drill for the wall penetration
I never saw anybody install the mini-split with the condenser unit on the ground. Most installations for the condenser unit are put on two hangers on the side of the building that come with the unit. After installation, the system needs to be vacuumed dry with a vacuum pump then, the gas needs to be installed in the lines with a refrigerant with proper instrument readings.
The do it yourself, model of the Mr. Cool Mini split has several options. we chose to mount to the ground because we already have the concrete pad ready. the do it yourself model is precharged and does not have to be vacuumed. Basically, once the seal is broken on the lines, it will put the appropriate pressure for you.
@@sethcraftworkshop It's not about the correct pressure. You vacuum out the system to remove air which over time destroys the AC unit
@@heatherpoole4951 they are designed to not have to be vacuumed. Even many of the new whole house units come precharged now.
It's pre charged, that's why it's twice the price of others. No HVAC guy needed.
If the compressor is sent in vacuum and the lines are sent charged, then they have thought of it all.
Idk about your local codes but what I've been told from NEC code is that you shouldn't run romex in conduit as it heats up. It's better to use individual conductors
I'm sure the book meant 10 gauge stranded wire, and I'd crimp some spades on it
Very interesting. The run is very short and will be in the shade most of the year. At 12 amps max this unit should not heat up much.
Why did u use 10 awg instead of 12 awg, from my understanding 10 awg is meant for 30 amps, none the less awesome video
I'm pretty sure that's a wet location so it either has to be UF or thhn. The price you paid for the nm cable you could have bought thhn and been safer and probably cheaper. Nice job, but one question is why the line set coiled up? Can't you order a shorter line set?
@@Hunter__14 I have the same question. Will be building new construction with dedicated 20amp circuits for each unit. Not sure but I think I would need 12ga solid wire.
Yes, Romex is not rated for wet locations.
Isn't it a safety hazard to have a circuit breaker slot cover missing (where you removed the 2pole breaker and replaced with a single 20a breaker)?
Probably. Those cover plates can be purchased to cover the hole.
Did you not have to purge the air out of the line set? Otherwise would there not be air introduced to the system?
The DIY mr. cool lines are precharged and do not require a vacuum.
Oh so the lines are sealed until they are tightened on the fittings? Then the line set opens up when screwed down?@@sethcraftworkshop
@@kurt357357I have the same question?? Is it like when you pierce the top of a tube??
Happen to have a box convenient
The electrician had installed that before the video.
With sidings this becomes little harder to do, isn’t it?
This build had hardie board concrete siding. It was not easy but worked ok.
The 12k 110v until I'm looking at from Costco says the max fuse is 25A, so shouldn't I get a 25A breaker? Also was the 10/2 wire included or did you buy it separately? thanks
a 25amp should be fine. The 10/2 wire was purchased separately. You can find electrical whips that are already installed in conduit. Makes things a little easier.
What if you find a leak at the connection ?
I also wondered that. My only thought is that it needs to be tightened more slightly. But I am not sure. The instructions did not give an answer.
Does it has to have a concrete base? Or can I make a wood one?
You can actually find plastic mini split bases on amazon. I used one last week and they are nice.
What about the excess line coiled up.does that get cut off?
This kit indicates that you are to leave the coil. Kind of annoying that there is so much extra. I noticed that MR. Cool now has line length options. Much needed to prevent such extra coil.
@@sethcraftworkshop thank you.
Wait wait, did you install the drain hose on botton of the outside units! You made this look so simple and it isn’t!
This was my first install for a mini split. It honestly was not that bad. Mr. Cool makes the install straight forward.
Can I use a10 gauge extension cord and cut the ends to make it easier ??
It would be better to use thhn stranded wire. You can buy that to length at a homestore or local hardware store.
Thanks

at 7:45 are there specific Torque specifications to tighten the connections? or just wing it? serious question :-)
There are torque specs. I did not have a wrench for that so I just did the best I could. Has worked flawlessly for almost a year.
@@sethcraftworkshop Thanks I appreciate it. I'm about to install a Blueridge DIY and I'm just taking my time to do it right.
