MRCOOL DIY Multi Zone 5th Gen 48K BTU Four Zone Ductless Mini Split with Ceiling Cassettes 6K + 9K + 9K + 9K – A Heating and AC System You Can Install By Yourself!

MRCOOL DIY Series Ceiling Cassettes provide efficient heating and cooling while remaining out of sight and discreet, making them a perfect fit for any space. The cassette features an easy, low-profile installation and can be recessed between all types of joists on 16 inch centers, including pre-manufactured I-joists. This makes it a perfect option for both new construction or retrofits. It doesn’t have strict installation requirements like other ceiling cassettes, so you’re able to install it in the location that suits you best, without using ductwork or wall space. The cassette works with the MrCool® DIY® Quick Connect® line set and the No-Vac® Coupler to increase the length of the line set. Not only does the unit offer quiet operation and multiple operating modes, but it also features the Elevation function that lowers the filter panel for easy air filter maintenance. Purchases of the MrCool® DIY® Series 6K and 9K BTU Ceiling Cassettes are protected by a limited lifetime warranty in addition to a 7-year compressor warranty and 5-year parts warranty.

The MRCOOL DIY 5th Gen Multi-Zone 48,000 BTU 22 SEER2 4 Zone Ductless Mini Split System - 6K + 9K + 9K + 9K delivers powerful, customizable comfort across four rooms in your home. With one 6K air handler (up to 250 sq ft) and three 9K air handlers (each up to 375 sq ft), this setup is ideal for small-to-medium sized rooms like bedrooms, offices, and sunrooms. Designed for hassle-free installation, the DIY Series features pre-charged Quick Connect lines, eliminating the need for expensive tools or professional labor. You’ll also enjoy peace of mind with a 7 Year Compressor Warranty (extendable to lifetime) and 5 Year Parts Warranty.

MRCOOL DIY 5th Gen Multizone 48,000 BTU systems can support up to five indoor units, offering flexibility for future expansion.

Feel free to mix ceiling cassette air handlers and wall mounted air handlers together in a system by visiting Building Your Own Custom Mini Split System.

The MRCOOL DIY 5th Gen 4-Zone 48,000 BTU 22 SEER2 (6K + 9K + 9K + 9K) Ductless Mini Split System with Ceiling Cassette units are super easy to install and require no special training or expensive specialty tools. The DIY system includes Quick Connect lines that are pre-charged with eco-friendly R-454B refrigerant. Due to the Quick Connect line set, you don’t have to hire an HVAC technician to complete the install. We also have simple video instructions on how to install a DIY Multi-Zone unit yourself!

The MRCOOL DIY Multi-Zone 48,000 BTU 22 SEER2 4 Zone Ductless Mini Split System - 6K + 9K + 9K + 9K can cool through the Summer, heat through the Winter, and dehumidify through the wet seasons. Plus, you can quickly check the temperature of each room in your home from the easy to read digital display or from the MRCOOL Smart Controller mobile app. The display on the front of each indoor air handler unit can also display troubleshooting codes and alerts, so you are always aware of any issues with your system. Operate each unit wirelessly with either the included remote or with the MRCOOL Smart Controller app for Apple or Android devices. You also have the ability to control your mini-split unit with Amazon Alexa or Google Home.

The four MRCOOL DIY Multi-Zone air handlers included in this set provide directional control of the heated or cooled air. This distributes the air evenly so everyone in the room can stay comfortable. If you are in a situation that requires forced cooling, you can set your MRCOOL DIY System to manual with the button located on the right side of the unit under the front panel. In this emergency operation mode, you can test the cooling operation of your unit after installation or to complete a maintenance task.

In auto mode, each unit provides air for your home at your desired comfort level. Set your desired temperature, and the HVAC unit will determine how much heat or air conditioning is needed. You can also set this system to a drying function, which will continue to control the space’s air temperature while dehumidifying.

Use the sleep mode at night to save money on your utilities bills and use less energy. Sleep mode operates in an 8 hour window once turned on.

The MRCOOL DIY Multi-Zone 48,000 BTU 22 SEER2 Four-Zone Ductless Mini Split Air Conditioner System - 6K + 9K + 9K + 9K comes with many options, so you can customize your system based on your needs. Limit your energy usage and save money on your utility bill by using the system’s timer function. If your system begins to run low on refrigerant, an alert will appear on the easy-to-read display on the front of each air handler, letting you know there may be a leak. If you desire to keep a room quiet and minimize lighted alerts, you can mute each indoor unit. By muting the system, the buzzer for alerts will not sound and the LED lit display will turn off. Should the unfortunate event of a power outage occur, the MrCool system will automatically shut off and then back on with the same settings once power returns.

Easily maintain your MRCOOL DIY Multi-Zone 48,000 BTU 22 SEER2 Four-Zone Ductless Mini Split Air Conditioner Unit with alerts and reminders. Any troubleshooting codes will appear on the front display and the user manual contains an index for common codes. Air filter cleaning alerts are automatic, and you can easily keep the minimal indoor units clean with a dry or damp cloth.

SHORT DESCRIPTION
MRCOOL® 48k DIY 5th Generation 6 Zone Multi-Zone Mini-Split Condenser 230v
LONG DESCRIPTION
We’re excited to introduce our new 5th Generation MRCOOL® DIY® 48k BTU Multi-Zone Ductless Mini-Split Condenser, because it’s better than its predecessor in nearly every way. You won’t need the services of an HVAC professional when you’re setting this unit up, because you can do it yourself, which saves lots of time and money! This condenser enables you to heat and cool up to 6 separate spaces equalling up to 2,000 sq. ft., meaning you’d be able to cover an entire home in the completely efficient comfort of a single DIY® system. You can install this system on your own because our innovative, patented pre-charged Quick Connect® line sets allow you to skip the lengthy and complicated process of evacuating and charging the system. These line sets are filled with R-454B refrigerant, a much more ecological and proficient upgrade from the previous refrigerant used in the last generation. This switch helps the system achieve impressive efficiency levels, like 21.8 SEER2 and an HSPF2-4 of 10. These line sets are sold separately. Once you install your system, you’ll be able to explore the variety of ways you can customize your comfort. For ultimate control, you can integrate system operations with the SmartHVAC app, available for Apple and Android phones, allowing you the ability to set schedules, manage modes of operation, monitor your systems all with the touch of a button. The app even enables you to set up integration with Amazon Alexa and Google Home, meaning you won’t have to move a finger to make your home more comfortable than ever. We pride ourselves on having one of the best warranties in the industry on this unit! Once you install your condenser, you’re entitled to a 5 year parts warranty, a 7 year compressor warranty, and, if you subscribe to the MRCOOL® Care Program, a Limited Lifetime Replacement warranty. The MRCOOL® DIY® is the right choice if you want fast, efficient comfort that won’t let you down!

Great quality and value
Size: 7-Quart
Heavy duty and well made. Love that it’s pre seasoned. I’m using it to bake artisan bread so it’s important that the lid fits well, which it does. The price is great for a pot this size and quality. The black is perfect for the color because I’m preheating it at 500 degrees Fahrenheit and baking at 450.

lower quality casting but very functional. reseason is a must. good purchase otherwise
Size: 2-Quart
this was an amazon primeday impulse buy. initially when reading the reviews i was skeptical of its quality at all and attempted to cancel but i could not(too late). i figured it wasnt the end of the world when it showed up as i only payed 20$ on sale for it. well, it turns out thats a steal of a deal for this pot. when i opened the package i checked it all over with a magnet. who knows it could be lower quality pot metal but its definitely ferrous material. the season on it is real, like what you find on a lodge pan but not done well, it was sticky. so i boiled a pot of water and scrubbed the lid and pot insides with a scour pad to remove most of it. it looks exactly like youd expect cast iron to look and it has a smell reminescent of a deseasoned wet cast pan. so i trust it. my version should be 2qt, i do not know if they make larger versions. i trust it to work in the future and it seems like itll make great stews and soups. possibly even a good camp pot if youre into carrying cast iron with you. its not massive and its not overly heavy at maybe 3 lbs. it was a good buy and im happy with it. plan to add a bail so i can use it for camping as well as kitchen use. in conclusion its a lower quality casting but still very functional. it must be reseasoned to be useful but for the price i almost expect it. most cast iron cookware are not made to the spec they used to be and thus require love from the owner to really work well.

Amazing Dutch!
I've been on a cast iron craze recently. I think back to college when I'd watch Yan Can Cook, and Chef Martin Yan would lean over into the pan and say, "It's got to be hot hot!" I finally realize what he means after all these years of cooking. Heat makes for awesome cooking. It gives wok hei. It makes the difference between a juicy, seared steak vs a dry, tough one. When I discovered this secret, I was like a kid in a candy store, picking this cast iron, that cast iron, another cast iron, please. When I bought the 5 quart Amazon Basics dutch oven, I figured that at the low price, if it came with issues, it wouldn't be an expensive loss. I was impressed with the packaging. Amazon did not want this pot to break, so it had form fitted Styrofoam everywhere, pot and cover nicely separated. There was a nice Amazon Basics logo on the bottom of the pot. Upon close inspection, I thought I found a hairline crack on the cover. It seems when they casted it, part of the iron folded over on itself and formed the line. Someone then took a sander and sanded part of it slightly. What I thought was the hairline crack was actually the edge of the polished surface. The next day, I cooked bacon in it. I fired up the Camp Chef Explorer stove and cooked two pieces of bacon in the pot. I also flipped the cover upside down and cooked two pieces of bacon in it. The cover makes a very nice ad-hoc skillet. After it cooled, I inspected the cover again, and it is not a hairline crack. The bacon seasoning started covering up both the polished and unpolished surface into a nice, uniform seasoning. The following day, I made chicken stew in it. While carmelizing the onions and carrots, I made another nice discovery. The flat bottom lends itself nicely to efficient stir frying. Sometimes, in a wok, I come across the problem of the bamboo spatula not being able to get under the food, so I end up chasing the food up the sides of the wok unable to flip it. The part of this dutch oven where the bottom meets the sides creates a nice angle that pushes the food onto my bamboo spatula for easy flipping. Yesterday, I took it to my parents' house and made artisan bread in it. Everyone was impressed with the crispiness of the bread crust. Everyone came back for seconds. Needless to say, I no longer have the dutch oven. My mom liked it so much I gave it to her. It's almost Mother's Day, and who would say no to their mom? *ahem* Amazon...another cast iron, please! LOL PS: The lid fits a 10 inch skillet but not a 10.25 inch skillet. It falls into a 10.25 skillet.
