There are a good many mini split “how to” videos available on line; some better than others. I recommend looking at as many as possible because none encompass all of the possibilities (good or bad). When you watch those videos you will see the packaging, the carton inventories, and then steps of procedure. So far there is little to take issue with but in the procedures video you will see the connection of the line set near the evaporator which is the first line set couplings. Post coupling you will be instructed to UV Tape the coupled line set and move toward the coupling of the line set from the evaporator to the compressor.
DON’T DO THAT.
After connecting the line set to the evaporator, UV Tape the line set from the evaporator to about 8” from the line set to evaporator connection ( or whatever space you think you will need to work on those connections). If this is taped all the way to the compressor before the connection at the compressor is established and the line set is vacuumed you will have to cut your way into it to check those couplings in the event there is an indication of for a leak. Since it is a UV Tape spiral any cut and forced opening to allow room for re-torquing those connections will be sloppy and probably lack having the integrity of the rest of the wrapped line set. I suggest wrapping the line set about 8” below the coupling and wrap to the end of the line set.
I have to express a measure of disappointment regarding the manufacturer’s DYI marketing approach as contradicted in operating manual notations as necessarily being installed by a trained professional; can’t have it both ways COST WAY.
The change of disposition is because there are at least four catastrophic results that are very possible: you could blow your head off, you could be electrocuted, you could suffer frost bite, you could be blinded, and you could be fined thousands of dollars. A meager mention of the need for an R-32 Vacuum Pump is lacking and in need of a fuller explanation. An R-32 Vacuum Pump is designed to prevent sparks near the refrigerant. Adapters are not the answer to be able to use a vacuum pump that is not R-32 compliant.
When I vacuumed my line set I had a leak. At this point I have a real problem because I know the evaporator line set is reliable but I can’t be sure about the line set couplings I made. How do I determine where the leak is if all I have to work with is a vacuum pump? I can’t see a leak. Maybe if my hearing was better I could hear the leak but sadly, my hearing is failing. Should I roll the dice and tighten all connections and risk opening the refrigerant valves? If I do but didn’t tighten the connections enough I now have refrigerant leaking into the atmosphere. Now, I will need to call an HVAC technician and that means I have lost the DIY cost savings.
At this juncture I elected to purchase an adjustable torque wrench and a nitrogen cylinder and gauge set. Nitrogen under 150 lbs of pressure makes a leak audible and I did not want to risk releasing the refrigerant without being absolutely certain the gas would be contained. The leak turned out to be the connection of the compressor. I made the correction and opened the valves for the flow of the refrigerant. Saving THE FYI advantage is important but more importantly is please of mind; knowing there is no leaks.
The unit is nicely made, light, and unbelievably quiet. Once the power was turned on it performed as designed with one exception; WiFi readiness. More on that later. I installed the remote controller/thermostat batteries and read the controller instructions to find illustrations that didn’t look like my controller. Confusion is never helpful when attempting to do something that is new. I am already uncertain of how to proceed and I have illustrations that don’t seem to be for my application. Looking for a way to a happy ending, I encountered more confusion regarding QR Codes. The QR Codes are smaller than a US Postage Stamp and they are arranged in a block of 12 or more and I have to find the one that I need. I’m 78. My eyesight is failing! Is Cost Way only interested in the youth market? No one seems to care if the directions published are readable for ALL markets. The “right” QR contained the same information as I had already read in the manual. I set the temperature and the space immediately cooled to the point it was uncomfortable. The unit is faster and blows colder than the house system so I had to reduce it to find my comfort zone. It works well and I am happy with the evaporator and condenser.
The WiFi instructions are wanting. Connecting has been very challenging. Remaining connected is even more of a challenge. I don’t understand why a well written, photo guided, and proofread instruction sheet is so difficult to accomplish. I am struggling with several Chinese manufacturers because of this issue. It isn’t helpful to try to make one set of directions fit many different production models if disregards, and exceptions cloud the directions. In my career I have not found experienced English proficient technical writers to be expensive. Adding the cost of competent translators and/or technical writers to the cost of the product will amount to a fraction of the lowest measure of exchange. If I have to struggle to scan at codes smaller than a stamp at least make sure it produces information that is useful. I have connected once for about 80 seconds. I am “off line” at present.
CORRECTION: I am on line and WiFi is working.
I like the product and I would purchase it again.

Awesome AC, you’ll need double pole 15amp breaker and at least 12awg wire fpr connection. Comer with both line sets. The wall bracket needs to be rated at 200lbs for the outdoor unit, but is liftsble by one person. Comes precharged with 1 kilo of r32 refrigerant. Can connect to WiFi with AC Freedom app. On low fan speed runs very quiet.Looks cool inse and outside. Need to pull vacuum on lines before start. I used tripple evacuation method with nitrogen. It all worked well. Both envaporator and condenser unit can be installed by one person.

I needed a product that was easy to install and powerful enough for my garage. This mini split is better than I had hoped for. Installation may require a professional but was relatively easy for a do it yourselfers. I purchased the optional bracket from costway and it is also easy to install. I also purchased a non fuse disconnect, 220 line and a hvac evacuation vacuum. The install went smooth and the system works flawlessly. The unit has heat, AC, dry and auto modes. I turned the unit on AC and it is very quiet. You car barely tell it is running. Quiet but very powerful. My garage was finally cool for the summer and I look forward to being able to be comfortable regardless of the season. This is a great value for the money. I used the hvac vacuum to test the system for leaks and it was a perfect seal on my first attempt. Be sure to consult a professional if you do not have a basic knowledge of installation.

Instructions are very poor in the enclosed booklet. Sentences are not structured correctly into English from the Chinese company. The QR code that is supplied does not function correctly. Comes up with an error code. In the process of trying to install this and I have not had the opportunity to actually use it yet. Hopefully it works!

I picked this unit because of the Internet connection had to download the instructions for the remote because the one function had a couple functions that were dual functions, but once I figured out that the Internet popped up on the phone very easy and installed it my first time installing a mini split Air conditioner works greatest

So I had to return the item because electrician advised me that it was not the voltage that’s the only problem and the seller refunded my full amount. Thank you

I converted my large 3 cars garage that is about 900sqft into an open studio with 1 bath and there isn’t enough capacity from the existing unit to modify extra duct to this space so we went to find a solit unit since it looks much better than a window unit. This unit is black for the inside unit which is great since it fits the black theme for the room. We opened the units to verify everything is intact before hiring a contractor that can do both electrical and hvac to help us install this unit because it runs on 208V. Took the whole day to run the circuit for the unit and installing the inside unit on the wall and running the refrigerant pipes to the exterior unit. They also helped us anchor the unit on a large prefab concrete pad they had. The unit puts out so much cool air for this large open space. The very far corner is needing some help getting cooled so we also used a fan to spread the cool air around. For the money it’s worth it to have a clean looking unit on the wall vs having an ugly window unit. The contractor said the instructions were good enough for him to follow since he has already installed a few mini splits before. But it is not something I think I can do myself. And I recommend buying something about 25% larger than your sqft. Since this one is suggested for 1250sqft so I got it for my 900 sqft.
