How to Install Multi Zone Mini Split System (Cooper&Hunter) 2020

I don't see a torque wrench.

How did the lines get from the multiple indoor units to the outdoor compressor?

is A & B connected together through the compressor? Or does A have to be vacuumed separate from B? If A springs a leak, will B lose its Freon also?

No torque wrench?? Torque values should be in the installation manual. Most mini split installations have refrigerant leaks due to this missed process.

Does the kit come with the connectors to re-flare the lines?

There's not a lot of content on the multi zone mini splits

It's winter here, Just finished install. Can I use the heater option before vacuuming testing and opening the valves for the a/c

Do you have a video showing how to test each line individually?

Are the Exv’s normally open?

Do the multizone condensers share the refrigerant across all zones? If you pull the vacuum from one zone, is it also drawing down on the other zones too?

Nice video. I am going be installing a dual system one for the lower level and one for the master bedroom upstairs. How do I figure what size unit i would need?

When vacuuming, did you just use an adapter or do I need to buy a core valve removal tool?

You can have a zones on a ducted unit with individual control ?? by using motorised valves. You never mentioned that in your discussion. Also these units are noisey.

I just finished connecting everything for my Cooper and Hunter mini split but I have a question before vacuuming the line set. I had to use the copper adapter for the line set for the 18k head unit on the outdoor unit, however I noticed there are small copper flared rings that come with the bag with all the adapters. They fit perfectly in the adapter. I put the flare ring in the adapter before I applied the sealant and tightened it down. Then I connected that line set to the male flare of the adapter. Does that sound right? I could not find anything in the installation instructions about the small copper flare pieces but they seam like a crush ring.

are you able to pull a vacuum from each individual line (zone A,B,C ..etc) independently of the the main line before opening the refrigerant? example pull a vacuum from Zone A open the low and high pressure, then open the main line to the unit to feed the refrigerant.

From the looks of it, will all three rooms need to have a separate hole drilled out to the condenser, or is it possible to stuff the three lines into one hole with a bigger diameter? If that’s okay, which is better for looks?

That was a great overview of a multizone install. Not a lot of fluff. Good basic information. Thanks for posting this.

I am close to purchasing this system off of Amazon. Is that the only place to purchase your mini split system? Also, when installing the line set for each head unit to the outdoor unit, does it matter which locations the 9000btu, 9000btu and 12000btu are connected to? I'm curious if for example A, B, or C are designed for the 12000 or 9000btu head units. Thanks in advance.

Where are u located in Florida ? Can I pick it up locally

Are these pre charged?

Can I just call and get a tech guy to do all the installation fit me? Does your company provide that service?

Your video totally glosses over the power line hook up. The units are not marked and your video is worthless. Is this a three wire 240V system or a 4 wire—ground, neutral, 120v and a second out of phase 120v line? Which terminals do you hook up to? The video doesn’t show. I have two Sophia multi zone inverters; a 12 and an 18.

Do you have to used the remote control to control the system? If remote control is lost will any other remote control work?

I'm looking to replace many old window mount air conditioners with a muti-zone mini split system in a single family home. How do you select system size and the size of the units for the individual rooms? My room sizes vary greatly.

Nice and clean,thanks for the aducation

Can i use another line to go more than 25' from the unit? Is there like an adapter?

Thanks for the very well explained presentation...

All that I have seen with the ductless system, so far, have been retrofits; but I am yet to see a clean installation for a new project. Bearing that in mind, the mounting walls always seem to be exterior-walls-preferred.

In new construction, mounting on an interior partition could offer more flexibility; so my question is: Is a 3" PVC pipe located in a 3-5/8" stud wall sufficient to run all those lines from each a/c head? or can each of those lines just freely run in the walls uncovered? And lastly: If then running those lines under a slab-on-grade, what diameter PVC chase would you recommend as a minimum?

I suppose that with proper planning the condensate drain line could follow is own path, or even drain to indoor plumbing.

Cooper and hunter, why didn't you look for supper heat?

If you do vacuum from the main Valve do you need to open all the individual lines ?o they stay close

Hi!I'm Darwin from Philippines ,I'm an AC technician in Saudi Arabia for 5 years.its good to for me to know and learn how to install unit multi zone,I've never been installed like this for 5 years of being a technician.i appreciate much the way u explain slowly and easily.thank u for uploading ur video and shared it with us who wants to learn more and have an idea on how to installed multizone.this is my email [email protected] hoping to receive msgs and advices from u.more power and God bless.

Your supposed to use a torque wrench when connecting the linesets.

Except you could install zones aka electronic dampeners and control to heat or cool these zones to individual preference as well much cheaper than the 3000 dollars in equipment you'll need on a mini split. Not bashing the mini split cause I think theyre great in apartments with no ducts and not much room for thrm

Sir I need job, my mobile number worksop number +971559443796

Sir I need job I am AC technician, 12 years job, sir my From Bangladesh, my mobile number plz Sir call me +971559443796

Why does each lineset have to be a minimum of 10'?

Do all the rooms have to be in the same side of the house?

What the hell?? You cut and flared both ends?? Nice job of making work for yourself. You only need to cut and flare one end.

Which plant is produced CH?

36,000 BTU is how many HP?

Did you have to evacuate each zone (low side) individually? So my question is after evacuating the first low side, you went to do that to each zone following before startup?

Sir you make video in hindi language

Do you have to use A zone or can you just use b and c

Hello please what’s the wattage of the unit at max temperature

Also need a micron meter and torque wrench for fittings.
