⏱️⏱️Chapters⏱️⏱️
00:00 Intro
00:12 Installing a 3 headed mini-split
00:25 One of the heads will be going through a double ceiling
00:45 Took a drill and bit and drilled out the corners where we need to cut
01:05 Went upstairs to mark the plywood
01:45 Made the cut marks
02:15 Going to cut the drywall
02:40 Back after pulling the drywall out
02:50 Scored the drywall with razor knife and cut with an oscillating saw
03:08 Put a paddle bit wider that the saw blade and drill the corners
04:00 Something you may run into when measuring
04:15 The jog in the hole is for the freon lines
04:35 Before cutting, make sure there’s no electrical above you
04:45 They ran into that with one of the heads
04:55 The instructions are for offices, not good for putting in a house
05:13 This job has several complications. They have to adjust to.
03:20 Cutting the plywood
06:10 Be careful of falling debris
06:25 Need to move insulation back… The heat is flooding into the room
06:50 Put boards to support the area
07:20 The area for your freon lines you’ll have to support too
08:00 Pattern for the shape of the head
08:25 The pattern shows a gap, you’re not going to have it when it comes to rafters
08:45 They are doing the second head
08:55 Where the control wires go
09:50 Installation manual, pretty specific for acoustical ceiling
10:05 He’s showing you how to put it into a home
10:20 The supports are in the blue package
10:50 The drain and freon lines for the head
11:05 Where the lines will be pointing
11:30 Electrical will come in there. You’re using a 5/8 wrench
12:00 Installing the support bars
14:25 You have to keep an eye on the support to make sure it’s facing where you need it to
15:00 2 supports are done
15:45 Want to be careful when rolling the head over
16:10 Leave enough room on the bottom to adjust it if you have to
16:50 The kit has anchors for concrete
17:30 You could use the anchors if it was inside a wall, but probably won’t need them
18:00 Cut a piece of wood to keep the head 7/8 above the ceiling
18:20 Using 1/4″ roofing screws
18:52 Not really a one person job trying to get the head up there
19:10 Woops, cut the area wrong
19:20 Need to cut the other corner out
19:45 Had to move the freon lines and cut another hole
20:00 You can’t have the freon lines going out, may have to adjust
21:00 Using roofing screws to fasten it
21:45 The fun of working with someone you can’t see
23:00 Only thing stays same is everything changes
23:10 Heavy or awkward?
24:50 The small piece of board is a measuring device
26:10 The box for the cassette head cover
26:50 Little tiny package of screws in the box
27:10 The cover doesn’t go on just any old way
27:35 The wires have to go to a specific space
27:45 Where the wires have to go
28:25 To put the screws in you have to take one of the covers off
29:55 Tight fit

Transcript:
Fancy you being here? You caught me right when I was getting ready to do the three headed mini split. What they call a cassette in the ceiling and then split three heads. One of them is going through what is drywall ceiling on top of a plywood ceiling. So this is unusual. But what we did was the customer said he wanted one head here.
Basically, I do what the customer says unless it’s impossible or not a good idea. And then I took a drill, a drill bit drilled through. Then I took something in this case, I have a fancy drill bit. But you take anything stiff enough to go up there where you can find it and put it up in there? I went upstairs, measure, from it to the sides of the rafter, which is this right here.
And there isn’t one over here. It’s another unusual situation. But if it was only 22 and a half, which is all you get, I’ve had to use a hammer and wedge in other boards to make it wider so we could get that which I’ll show you as we go along, in. But right now, we try to find the rafter in the rafters right there side of it, and we can give ourselves, in this case, a set of 22 and a half, two in a 24 inch center rafter.
I put 23 there. Now, that we’re done measured up there. I made the marks here and here, and then took a four foot level that you can take anything that’s a straight edge. Mark. Put it up there. And then marked measured from that wall, put it up there. Marked measure from that wall. Put it up there, and marked. I tired to line it up with the doorway.
So we’ve marked it all out. Now we’re going to cut the drywall out. Then we’re got to cut the plywood out. That’s, again, like I say, unusual. There’s nothing in this house that is like a normal house. But you can take your notes from what I’m doing and you can use it in your situation. So now we’re going to cut the drywall out and we’ll get back with.
Now all the dirty work is done. We actually used a razor knife to go and then score it, the drywall. We’ve been making fun of coaches that do the ‘Ahh’ in their interviews anyway. I scored the drywall with the razor knife and then used this oscillating saw and did it a lot faster. Next, I’ll put a paddle bit in, big enough that I can get inside a hole big enough that I get the… Saw blade. Wood saw blade, sawzall blade in. So, then I drilled the corners.
Got that done. Now I’m going to hook up power to the sawzall and cut it out. Now, incase you might not have noticed I’m going to point out something. The head that’s going to go up there is 22 and a half by 22 and a half. But we have learned if you just cut that size of the hole, there’s two lines that stick out further. And they are for the freon lines, we’ve made a two inch by three or four inch area on one corner to allow because we’re going to have the main unit outside over there with the left side window. We’ll have the freon lines going that way. Now, here we go making a big mess.
Probably, what I should suggest to you. Make sure that there’s no electrical up there. I was waiting for you to remind them. We actually had that on one of the heads. There was a line up there that went to an outlet all by itself. It just seemed like it was odd. Instructions are just for offices. Now the instructions are made for a acoustical slash. Ceiling grid. Foam ceiling type, so they don’t really work very well with putting it in a house.
But you can do it. And this is what we’re doing. We’re actually having one has to tin on the ceiling, then plywood, and now we have drywall on the ceiling then plywood. And we have got one that’s in a mobile home roof that has… Wood. Wood to metal. That has fake tongue and groove pine on it. And then above that would be a mobile home roof. And that’s going to be a journey in itself. But be careful, back to what I was saying to when you’re up there measuring how far where the rafters are after you put that piece up there to measure from, make sure there’s no electrical up there so you don’t cut it with your sawzall.
Do you recommend a hard hat? No, be careful. Plastic glasses would be good. Glasses might work. Well, in my case, it’s so hot they would fog up. They will do that. So now we’ve got insulation to move back. You feel the heat coming out? Yeah, there’ll be heat pouring out of there. It’s a 99 or something outside. So, you can well imagine what it is in that closed in area.
It’s like 105 up there. 105 on the… The floor. And then… See how close we are there of the wall and there’s not. Yeah, I’ve seen a bit.
Now, I put a board up here since there wasn’t a rafter there. And then I put some screws in it so we have something very solid to fasten to right here. And then we put a board right here. Stay even with this, and I’ll show you why. So that we can have the leg be able to fasten right here. I might have to do the same thing on top of rafter. For the rafter put like a 30” board up there and fasten it with screws.
But that area where the where you’re going to have your freon lines, you’re going to have to do something else to support it. In this case, we might be able to reach right here. If not, we’re going to have to fastened something to the rafter and then we can put the, the attachment pieces that they have and connect that to that. And then we might build the fashion to support this on top of this board here.
So that’s what we’re at next. Now, we’re going to take you through taking apart the box for the head that’s going to go up here. Not the cover for the head, but the head itself.
They give you a pattern. This is basically the shape of the cartridge, which is this right here or that? The cartridge with the head, itself the main body. And this shows you where the hooks are and everything. So if you want to have rods or something to fastened it to, you can have this to give you a reference. But this has a big gap, though.
It’s got like a one inch gap or all the way round, and you’re not going to have that when it comes to rafters unless you just cut the rafter, one of the rafters out, and then you’d have to add some wood to get that one inch a room around it. You get to see us go through this journey for the second time, and this is what we’re looking at.
The power will come in through here. And so with the control wires, there’s some more control wires that go in right here. We had to figure that out. But you take the screws right here. Right here. And that one. And this one, maybe that one. Now that one stays, that’s just grounds.
So you get those, then it pulls off and you could see everything inside there. We don’t need to do that right now. Where we’re going to pull this out.
So there’s instructions in here. There’s lots of stuff that will go to the cover or the cassette itself. Cassette cover. That’s a remote control, a number of other things.
Now, you get an installation manual, pretty specific, kind of tends to be for like a acoustical ceiling commercial situation. And that’s why I’m showing you what I’ve learned along the way. Now, this is upside down. It’s going to go up like so it has these support areas which we’ve been using that to help support it there in this blue package.
It has a washer and four both bottom and top, and you want to open them up a little bit more here. And this is kind of added, this is your drain and here’s your freon lines. Now, the freon lines are going to be pointing. To go down like. That. Like that. Yeah. So it will lay down. These freon lines will go through that slot right there that we made. We had to learn. So now these supports. And your electrical will come in right here.
See that hole with the electrical? Right there. What size wrench was this? 5/8. You have a socket there, if you want to use a socket. So this goes like that. Yeah. Probably should have got two wrenches. Try that socket? Ya I know. and then.
We probably should move it to one of the corners so it doesn’t try. To come through? Come out. Ya. I think I’ve got down in that slot. Yeah. That’s why you have to move it to the corner. You see that. Loosen it up. There you go. This will be facing the same way. Face it, to where it would hang the same. But this, when you tighten it up twice.
You’ve got to keep now on it. So that’s facing where you want it to. In these cases, we have a rafter right here to fasten to. Happens to be that we can do that. Now we’re going to do the other side, which is that’s going to face was going to face that way to fasten to that board up there.
The one’s going to face this way to fashion to that board we put up. So, that’s what we’re working on next move. So this one’s nice out. Yeah. Face this way. Let’s put this way, that way. Is it that way? Yeah. When you’re rolling it all, you want to be careful crush these.
I leave enough room on the bottom of it to adjust it up and down if I have to. That’s what the threads are for. All right. In the kit, it has these anchors for concrete and hooks, they would help you hook into that. Into the concrete probably would be from the other side. But we’re not going into concrete. It tells you what it’s for a more commercial, like inside of a concrete building with concrete floors up the next floor up. So that’s what that’s for. And you’re not going to end up using that. Those actually will pull down or.
In reality, you could use, if it was inside of the wall, inside of a wall, you could probably use an inside the wall to and suspend it that way, on one side. But we’re not having any of that situation in a house-house. This is really unusual house. So we’ve set it all up so we have the ability to put this up in there.
Now, this is supposed to be 7/8 of an inch above the finished ceiling. So we had a piece of wood that is 7/8 of an inch. So all I got to do is do that. And then he can fasten it while he’s up in the hot attic fastening through these holes. We have to use roofing skirts. We’re using quarter inch roofing screws with there. It has a washer on it and using a quarter inch driver and an impact battery powered gun up in the attic. So I can’t take a long time doing it because he’ll cook up there, which is part of the air conditioning guy trade. Now. So we’re going to get ready for that.
And I guess I’ll get somebody else come in here and help video us putting it up in there and we’ll get ready and he’ll climb up in the attic and away we go.
Not really a one person job more of a two, probably a three person job. You got that wrong. Ooh, that’s not gonna work. Nope. Come back down. You got it cut wrong. Okay. So this one’s got to turn this way. We got to cut this corner out. Come on down here. Did you get down like that. All the all of them got to be changed to the bracket. So I’ll lower down to he Fisher to this whole. You can just cut another hole right next to it, Dad. I know what you’re saying. I don’t think it will let me…
I want you to know that we end up having to move the freon line over here. Change the brackets. I made a hole on this end so that we wouldn’t hit the rafters on this side. So that might not be anything but the choice you have is that so it’ll come out the side if you turn it this way or go into the rafters.
You can’t have the free lines going out, have to go inside the rafters. So here we go. It’s kind of heavy. Probably 40 lbs, more awkward than heavy. 40 or 50. I’m hanging up on something up there. You’re good. together. Which one you want to fasten to first? Let’s do this one. What’s this corner? That’s my… I’ll leave it right here. Good. Yeah. He’s using roofing screws, that have a quarter inch drive and a washer. But you can use what you need to.
You want to do the other side this thing in? there. So. It’s not going to reach right there or I’ll get you this other this corner. All right. I went over there. Bomb. You need me to come over there behind you? I got it. All right.
The one closest to the. The wall, the kitchen in the barn there. It, I suppose, should be reaching that one to the end, Drew. Can’t get us through. Got in there. Right. The other corner through. What do you talk about? We’re going to the other corner. Which one? I didn’t want to. Here. I can be over there. Do you.
Go ahead. I’ll hold that, for you. I got it. I don’t know why I need a board. Less group of interest. I guess we need a board on top of that one. Yeah. Is that? What are you going to need on the other side? A short piece. Always plan for things to change right, Dad?
Right there. Is it heavy? Or is it more just strain? After having your arms up there for a while, ya. It’s like the guy pushing the ball up the hill, Dad. Yep.
What do you need to do that? All right, do you want to do the other end? What would the tip go that was in it? Let me have that tip over there.
He needs to go up a little bit? No, he’s got right where he needs. Right there. I think all the uncomfortability you’re getting right now, he’s way more uncomfortable. People pay to work out. I work out. You know, he’s cooking. You’re just straining to talk about a weird hand. What about this other side over here. I need a very short vertical 2 by.
Did you already explain them what that is? That’s his measuring device. Ya, I already explained. Somewhere in there. That stuff you got to plan for, right? Losing screws. I have a screw lose. All right. Happy? I’ll be happy when it’s done. You’ll be happy when it’s blowing cold, right?
All right. So this says four-way cassette, but we’re doing three-way pioneer. This is the box for the cover. Don’t lose these. Yeah, a little tiny package of screws inside the box, you don’t want to lose them, because that’s what goes into those four areas right here. Now. Hold up. I’ll get you a gun. This does not. This cover does not go.
Really, we need to take that cover off. Why? So when we come back through and hook up all the electrical units. You have us do. But we’re not doing that, just yet. Where we can just this comes down, we can get into. All right. So these wires have to go on a specific place and they go in right here. So that means… Over one more. Other way. Just keep going right one more, like that. So right.
There you go. Like that. There. And by the way, that’s tape in here you can pull out. Well, they can reach that from the outside. Yeah. Now this is these wires have to go. They show up right here. I already showed them. So these wires has to be where they can reach into there. And that’s that you… You’ll see when you get in there, you’ll see where they go. They’re pretty. And we’ll show you self-explanatory. Now, to put the screws. These screws in, you have to take this cover off. Now, you push these little springs like that, and this will literally pull out. And these can hang. All right.
Remember, this is going to go back over. And this seven-eighths right here is why we got to have that 7/8 that. I don’t know if your going to… Watch out. The one I’ve got, put the washer on that. Yeah. If issue is you’re right up against the wall on the other side there. Oh yeah. Your, uh… We have no screw? Here you go. Hold that for showing. A little bit of finagling, right Dad? A little bit of adjustment. Finesse.
You know I can look up in here and see where the screws in relation to the hole. I don’t want to over tighten it. One more screw? You may have to cut this out. Yeah.
