DIY Ductless Mini Split Install - MrCool Unit

so on my property I have this beautiful shed that really isn't being used for anything other than miscellaneous store is for odds-and-ends it's such a shame because it looks much more like a tiny house rather than a normal shed with that I have decided to turn it into guest quarters so that when somebody's staying here they'll have their own accommodations and space of course what the be in Texas AC is a must so that is my starting point installing a mini split now with the space being pretty small and it's only 168 square feet I'm going with the only do-it-yourself mini split on the market currently it's made by a brand called mr. cool I started by clearing out a walking path and work area on the wall where I'll be mounting the inside unit which is called the air handler then taking some measurements to make sure the unit would fit I used a stud finder to locate and Mark the studs inside this back wall then remove the bracket on the back side of the air handler and started pre drilling 4 holes to mount it when placing this bracket I lined up one column of holes to be in line with the stud and this leaves the other side shy of the next stud however so with one screw holding the bracket in place and a level on top I pre drilled the hole locations for the second column of screws that wouldn't hit a stud in this way I could remove the single screw I placed in the bracket and tapping some wall anchors I made sure that these were flush and then remounted my bracket next I started lining out where I needed to drill a hole in the wall for the plumbing that will connect the inside unit to the outside one these units are supposed to come with a template but I wasn't able to locate mine it's no problem though I measured over from my left row of holes six and a half inches and made a mark then I found a circle that was three and a half inches in diameter and traced around it to cut this out I could have used a hole saw but I didn't have a three and a half inch bit so I went with a jigsaw instead I used a drill bit to punch a hole big enough for my blade to fit in then neatly cut around my pencil mark that takes care of my inside hole now I need to go to the outside and cut another one that's perfectly in line with it if you're wondering that is my mother's finger when you're punching the center hole of the inside circle make sure that your bit is long enough to go through the entire wall and also punch through the outside wall this way you can go to the outside trace you get another circle that is three and a half inches in diameter and then cut it out with a jigsaw with a hole cut all the way through I took the plastic sleeves that come with the unit and test fitted it now they do come along so that they can fit through a variety of wall thicknesses so I made a mark on mine where it needed to be cut down then used a jig saw to cut it to length I place this on the inside hole then capped it off on the outside and now I have a smooth passage for all of the plumbing of the unit to pass through the wall so the thing about mini splits is that they are pretty simple to install but it takes professional equipment to charge their refrigerant lines the mr. coil unit though comes with the line set this long white line already charged for you this makes the unit DIY a bulb but it also means that it comes with a stock length of line set that can't be cut down so keep in mind when you're picking out your location for it that you'll need to coil up and stow away in the excess line once I fed through the start of the line set I paused and also fed in the drainage line this will drain out any condensation and moisture that the unit creates I push one end through the wall then connected the other end to the back of the unit making sure to give it a few tugs and see that it wasn't going anywhere oh and also it doesn't say it in the instructions but there is a plastic corner cap on the backside of the unit that you need to remove and that's what allowed the units you mount flush to the wall whenever you get it up on its bracket having two sets of hands for this part makes this go a lot easier my mom was around and offered hers up she got on the outside of the shed and pulled the line as I was on the inside feeding it through take your time especially if you're going up a ladder to get this entire line through without kinking any of those hard lines let me get up on my stool a little bit just gentle pools at this point now just try to pull the rigid line if you can't you just pause for a second once you get close it is incredibly simple to get the air handler on the mounting bracket as it how they live that you can set it on and then just let it hang really awesome once the top is hung you need to make sure the bottom is in line with with that line stepping inside of its space and then push on it until it snaps into place and that is the inside unit done but before jumping out to wire in the outside unit let me talk to you about this video sponsor which is simply safe simply safe is an incredibly effective reliable home security that will make sure your home or in my case my shop is safe since building my shop I've been looking into plenty of security systems but settled on simply say for a variety of reasons I love that all of the devices can easily be set up by yourself so no waiting on pros to come in it's very easy and intuitive also it's very fair pricing and the fact that there's no contract or hidden fees is a plus now even though you're getting a good rate the system is professionally monitored 24/7 and they'll call the police if anything should happen and yes the system still works even if you lose power Wi-Fi or the system is attacked you can customize your system by picking the components you need or want there are so many options including cameras motion detectors a smart doorbell and a variety of sensors that will tell you if a window or door is open if you're interested in checking the system out then please visit simply safecom slash April thank you simply safer keeping all of my tools safe now let's get outside to wire in that unit I'm comfortable tackling the simple wiring on my own so I pulled off the covers and started by wiring in a powerline I purchased outdoor flexible conduit called liquid tight and this came with a 90 degree fitting on one end and a straight fitting on the other it also had wires routed through it went bourbon and me from having to buy a power cord and fish it through man I just had to strip the ends and crimp on some Spade connectors in the other knockout I ran in the wiring from the line set and this comes with a connector already wired on for you I first terminated the line input ground and neutral wires and this was as simple as backing off of the screw slipping in that Spade connector I attached earlier and then tightening back down then I connected the output line which goes up to the air handler using that simple push together connector they already wired on and that's it so next I pushed everything inside so I could close the cap and reattach it with the screws I moved my unit down to the corner of my building so that it would open up the back and that's not only gave me a better airflow but it also gave me a sneaky spot to coil up my extra line set and stow it away I don't currently have power out here so temporarily or maybe permanently I'm gonna be running it off a quiet generator stowed away in this little cranny of the building however instead of plugging directly into the generator I first wired in a fuse disconnect box there's a fuse which adds a layer of protection between the unit and the power source so that if there's trouble the fuse will trip before damaging the unit after mounting the box I used one of the bottom knockouts to wire in the other end of the power cord that runs the outdoor unit finally on the remaining knockout I purchased a heavy duty extension cord I cut off the female end strip back the ends and wired it in and I didn't leave a ton of cord here because honestly the generators gonna be set right in the spot alright getting down to the end so hang in there one of the final steps was to try to blend in that line set to the side of the shed and I found this Raceway material specific for line set at a local HVAC shop and it was hard finding one that sold to the public so if you have trouble I know that there are similar products you can purchase through Amazon once I tidied that up and knew the unit wasn't moving I finally connected the line set to the unit with these lines being pre charged you can't disconnect these lines once you connect them or how to get professionals out to recharge the lines so before removing the protective caps and making connections just make sure the unit is where you want it to be there we go that is a drastic improvement over yesterday still need some painting on the trim that I had to put in but the lines that comes out goes down the Raceway coiled up the excess back here got it all wired in put it in a disconnect and eventually a generator will go here then I can plug the unit into whenever I want to use it you even buried the drain line that comes out other than paint that's a job done and that's it overall it's a very easy install probably the hardest part is tidying up that line set and honestly it's not that difficult to do if you're looking to install a mini split then I hope this video has helped you out and of course if you have any questions on what I used in the video there are links to you down below stay tuned as I do more projects converting the shed into guest quarters I'll see you soon welcome to simply safe thank you
