MRCOOL DIY Multi-Zone Mini Split | Electrical + Testing + Initial Review | Ep 3

День тому

Part 3 install of the @MrcoolComfort ductless 4th Gen DIY® Multi-Zone Mini Split system. This 48k BTU 20.5 SEER unit can add up to 5 zones. We'll be installing 4 head units... 3 - 9K and 1-12k. We run all the electrical, test the system, and I provide my initial thoughts after running the system for a couple weeks.

Great to hear!

Great video series. I was just quoted $4000 per head for professional installation. On a 4-5 head system that could be $20,000. Nope!! After watching this, I am ordering us a Mr. Cool system. Mr. Post Frame saves the day again!!

One thing to consider Paul, the head that's in your canning kitchen might need a deep cleaning more often than others. I've found the small squirrel cage fan in the head unit is a magnet for airborne grease, then grabs dust particles and becomes a fuzzy fan that is less efficient at moving air. The one in our kitchen area needs a deep cleaning twice a year and we do use our kitchen for cooking, every day. I'm making a video how to clean these units. 6 mini split installs under under my DIY belt, all still going strong. Couple of them have loops in the line sets, some vertical, some horizontal. Nice work on your install. It takes time for a clean installation, especially with the internet checking your work.

For the condensate trap you can put mineral oil in the trap during winter. It will not evaporate during unused months. As for septic if you have not sure how that will affect that system. I know we use mineral oil in basement showers that are rarely used to keep sewer gases from coming up, the mineral oil will not evaporate.

If I have no problems running a 5 ton and 2.5 ton central AC system in my house with a septic system on the South Texas coast. He should be great, my 5 ton alone can put out tons of water a day and it's been running for 20 years.

@01Hokiefan 7 місяців тому

@@TdrSld water is not the issue going into the septic. He will not run the ac for a long period during the winter so the trap will evaporate dry. So I am suggesting to add mineral oil to the trap during winter to keep full and no sewer gas. But issue I don’t know about is when ac is turned back on and that mineral oil goes into septic what the affect on that system is for mineral oil.

Excellent DIY video. Very comprehensive video that gives me the confidence that I can do this. Building a shop and will definitely be using these. Keep up the good work.

@Overpar73 7 місяців тому

Very nice system Paul, I'm looking forward to installing my system this fall, I just need to figure out what size and how many units I will need, I'm sure you can help me with that!

@ASiembieda 7 місяців тому

Were those standard or metric crescent wrenches you were using? 🤪 loved seeing this little series and getting first hand info on the installation of the mini split! Thank you for the information!

@MrPostFrame 7 місяців тому

Ha...thanks for watching!

@One-Crazy-Cat Місяць тому

I got one those 48k units I’m doing now…. It says 60 amp max breaker so I used an existing pool heater and pump 60 amp feed sub panel and #4 line that existed again. Put in a 60 amp disconnect where there was an existing box. Hella hard to connect them #4 wires into that unit but seems worth it. It says min 40 amp so I assume 40 is the draw. That would be #8 wire and probably easier (and cheaper) but I had this existing pool breaker sub panel fed from the 60 and nicely buried with a ground rod as well for a double ground as one #4 come from main and they did a rod with #4 I figured as it says 60 max why not use what’s there. I made my whip out of #4 wire and flex 3/4. Like I say was hella hard getting them big wires in. Used hammer crimped #4 connectors to the unit and heat shrink over those.

Thank you for the info! Electrical tape for medical use?Okay if you don't have duct tape!😅😅

@MrPostFrame 7 місяців тому

Ha...yes electrical tape was more accessible at that moment.

@johnmartin6899 2 місяці тому

First of all, great video and very informative. Thank you posting. a couple of questions. Can I order directly from them as you did? and you mentioned something about 2/3 of unit has to be hooked up. I want to buy a multi zone unit/s but I'm not ready for all the heads until my next stage of my build. thanks in advance.

Did you purchase from a local distributor or Online? Where we live AC isn't a dire necessity. There are a few days each summer where it would be nice to have. We end up with all of our blinds drawn on those hot days. It's like living in a cave. The Heat pump aspect is probably as important if not more. We heat our main floor with a wood burning fireplace. But on those transitional days where a little heat would be good but a fire would drive you out of the house. We have Cove radiant heat which we use now on those days, but a Heat Pump would be more efficient. For our 1500 SF house I would put an 18000 BTU unit in the great room. That would be more than sufficient to cool the whole house as we're very will insulated with spray foam and 1" of foam board on the outside of the studs.

MRCOOL is sold online through Amazon or your local big box hardware store (Menards or Home Depot). I'm looking forward to see how this performs in the winter. Our radiant heat will be used but I don't have separate zones setup so we'll use the heat pump to supplement in the office spaces.
