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.

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..😎

@@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 think the homeowner was going to clean up the install so maybe they will find a way to coil this correctly.

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.

@sethcraftworkshop Жыл бұрын

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.

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.

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.

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?

@sethcraftworkshop Жыл бұрын

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.

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

@sethcraftworkshop 8 ай бұрын

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.

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

@davidstewart1153 Жыл бұрын

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.

I’ve been watching several videos, and everyone says you need to ‘vacuum’ the ‘lines’??? But I’m confused; if the system says ‘pre charged’ isn’t it supposed to be installed without vacuuming?

I'm guessing the people that leave those comments are unfamiliar with the new Mr. Cool pre Charged mini split. This unit is designed to install without vacuum.

@carlcapello9956 Жыл бұрын

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.

@sethcraftworkshop Жыл бұрын

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.
