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.

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..😎

@catsspat
@catsspat 9 місяців тому
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
@sethcraftworkshop 9 місяців тому
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.

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.

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!

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.
@sethcraftworkshop
@sethcraftworkshop 9 місяців тому
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.

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
@sethcraftworkshop 10 місяців тому
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.

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.

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.

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?

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.

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.

@user-sv4og9tr6c
@user-sv4og9tr6c 8 місяців тому
The wire used from the mini-split to the disconnect (circuit breaker is NMB). According to the NEC electrical codes, this is an incorrect usage of this type of wire. The proper wire should either be Thhn/Thwn or UF cable. Would fail an electrical inspection wired with NMB.
@sethcraftworkshop
@sethcraftworkshop 8 місяців тому
Is that because of the possibility that moisture could reach the wire?
@user-sv4og9tr6c
@user-sv4og9tr6c 8 місяців тому
Yes. Inside a conduit is not a location. The wire is located wherever the conduit is, therefore you have installed NMB in an outdoor/wet location which it not rated for. A conduit located outside is considered a wet location.

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
@sethcraftworkshop 10 місяців тому
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.
