MRCOOL DIY Multi-Zone 5th Gen 55K BTU Five Zone Ductless Mini Split with Ceiling Cassettes 6K + 6K + 9K + 9K + 18K – 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 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 55,000 BTU 22 SEER2 5 Zone Ductless Mini Split System - 6K + 6K + 9K + 9K + 18K is ideal for homeowners looking to efficiently cool and heat five rooms of varying sizes. This system combines high performance and flexibility with DIY-friendly installation, so you can skip the HVAC crew and save thousands on labor. Everything is powered by a robust 55K BTU condenser, backed by a 7 Year Compressor Warranty (with optional lifetime coverage) and a 5 Year Parts Warranty.

MRCOOL DIY 5th Gen Multizone 55,000 BTU systems can support up to five indoor units—the maximum supported for this condenser.

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 5-Zone 55,000 BTU 22 SEER2 (6K + 6K + 9K + 9K + 18K) 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 55,000 BTU 22 SEER2 5 Zone Ductless Mini Split System - 6K + 6K + 9K + 9K + 18K 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 five 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 55,000 BTU 22 SEER2 Five-Zone Ductless Mini Split Air Conditioner System - 6K + 6K + 9K + 9K + 18K 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 55,000 BTU 22 SEER2 Five-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.

Dude, it's not just a horror novel
Format: Paperback
This is to the previous reviewer (C. Scanlan). If this is just a horror novel, it failed miserably. It is not exactly a blood ’n gore thriller. Compared to Stephen King, it is pretty tame. What puts the horror in this book is that it is social commentary. Mary Shelly is not just trying to scare us. It is more than just a “Friday the 13th” movie. Mary Shelly is delivering a message. It seems that everyone understands this except this reviewer. There have been several different interpretations of the novel (see [...] for 10 different meanings of the novel). ICE takes the interpretation that Shelly is saying science can go too far. This is a perfectly valid interpretation. One can disagree with this interpretation but let’s not resort to name calling and personal attacks – that those who hold such an interpretation are doing a “low level attempt to cash in on home schooling Christian paranoia and fear of health care” or believe that “AIDS [is] the fruit of sin”. My wife and I are Catholic parents and we sent our children to public schools He mocks the idea of a secular fundamentalist but then demonstrates what that is. A religious fundamentalist sees anyone who disagrees with him as being of the devil. A secular fundamentalist sees anyone who disagrees with him as guilty of “brainwashing” others. In both cases, true dialogue is impossible. Another thing that a fundamentalist does is that he sees things in opposite extremes. If you are warning of the dangers of trusting too much in science then you must be against science. There is no middle ground for the fundamentalist. If you see that science can sometimes go too far then that means you are against health care. But this is a non-sequitur. Nielson writes “Frankenstein’s placing of the creation of life within the scientific method first destroys the unrepeatability and systematically eliminates the other elements [of hope, love, beauty, creativity and sacrifice]”. Nielson is not criticizing the scientific method in total. He is only criticizing it in the creation of life. The reviewer writes “He thereby easily and explicitly condemns the whole process and philosophy of the scientific method”. But Nielson is not condemning the whole process of the scientific method. He is only condemning it in the creation of life. The reviewer then mocks the credentials of the critics in the book - “So who are these essayists superior to Norton's and Oxfords and free of deconstructionist feminist secular fundamentalism, experts so august Ignatius should want them mentioned on their product page yet are nowhere to be seen?” But this game can be played both ways. What are the credentials of this reviewer? Is this reviewer so august as to challenge these essayists? Again, this is merely an ad-hominem attack. I really do not care who has the best credentials. What matters is who makes sense. Sometimes intellectuals can make the dumbest claims. Read Paul Johnson’s book, “Intellectuals” (http://www.amazon.com/Intellectuals-Marx-Tolstoy-Sartre-Chomsky/dp/0061253170/ref=sr_1_1?ie=UTF8&qid=1421862888&sr=8-1&keywords=intellectuals). He compares the essayists unfavorably to “good solid Roman Catholic moral theology” from the likes of Richard A. McCormick S.J., who “is the renowned leader of Roman Catholic Moral Theology in the field of bioethics in the USA.” He overlooks the fact that A. McCormick S.J. has dissented from teachings of the Popes Paul VI, John Paul II, and Benedict XVI over contraception. The “renowned leader” in the Catholic Church in morality is first and foremost the pope. Since Richard A. McCormick has contradicted the popes, he cannot be a good solid Catholic theologian. Mary Shelly lived right after the Enlightenment – man is the measure of all things. She lived at a time when people believed that science will solve all our problems. This is called scientism. ICE contends that Shelly is saying that we may be expecting too much from science. It does not mean that Shelly was saying that we should reject science. And it does not mean that Shelly believes that we should go back to the Catholic faith. In fact, ICE acknowledges that Shelly was an anti-Catholic. But the Church believes that the kernel of truth can be found in others, even in anti-Catholics. This is part of the Catholic tradition. St Augustine learned from Plato and St Aquinas learned from Aristotle. ICE would take that kernel of truth and expound that with the fullness of the Catholic faith. You may disagree with the Catholic faith, or with ICE looking at Shelly’s book from a Catholic perspective. But this is at least as a legitimate an interpretation as any other. In fact, this interpretation seems closer to the truth than the others. This interpretation is the traditional interpretation, which means that it goes back further to Shelly’s time than the modern interpretations, and is therefore less likely to be in error. BTW, the reviewer wrote that “Opus Dei right wing publishing (or reprint) house is selling this novel is to milk the home school market and to support its own bizarre bio-ethical ideology”. This is factually wrong. The company that publishes Opus Dei’s books is Sceptre. But the publisher of ICE is Ignatius Press.

Love the Edition and Footnotes; Don't need the Cultural Criticisms
Format: Paperback
The layout of the book and the footnotes are each great. What mars the book, unfortunately, is the editor's need to make simplistic statements about cultural elements. Several times, for example, he addresses "feminism," even using the term "Franken-feminists" in a puerile manner at one point. As too many of these conservative Catholics do, he simplifies and comments about modern culture without nuance. In this case, it is simply unprofessional and inaccurate (i) to not capture the myriad differences in feminist thought (many of which he and his readers would accept) and (ii) thereby to make all feminists the same (e.g,, assuming the feminists of the 1970's are the same as today's.) This is all unfortunate because when he is just addressing the literary elements of the book, his comments are wonderful and helpful to the reader. Any reader should know that this presentation will be tilted in an unsophisticated and simplistic way toward a traditional Catholic view (a view that can indeed be defended well while still being careful and charitable to critics). With that caveat, he (or she) should still buy it and garner a good edition of the text.

Great edition
Format: Paperback
Love Ignatius critical editions. There are so many scholarly essays that are so vague and uninteresting, or worse, try to de-construct the writer's work. Ignatius critical editions' essays are wonderful and do not miss the timeless point of the great literature the series brings forth.
