MRCOOL DIY Multi Zone 5th Gen 55K BTU Four Zone Ductless Mini Split with Ceiling Cassettes 6K + 6K + 6K + 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 center 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 55,000 BTU 22 SEER2 4 Zone Ductless Mini Split System - 6K + 6K + 6K + 9K is ideal for small and moderately sized spaces where subtle and quiet airflow is key. This configuration includes three 6,000 BTU ceiling cassette air handlers (suitable for up to 250 sq ft each) and one 9,000 BTU unit (for up to 375 sq ft). With this system’s do-it-yourself installation and pre-charged line sets, you’ll save thousands by avoiding costly HVAC labor. Backed by a 7 Year Compressor Warranty (plus an optional lifetime upgrade) and a 5 Year Parts Warranty.

MRCOOL DIY 5th Gen Multizone 55,000 BTU systems can support up to six indoor units, giving you flexibility to expand your system later.

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 55,000 BTU 22 SEER2 (6K + 6K + 6K + 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 55,000 BTU 22 SEER2 4 Zone Ductless Mini Split System - 6K + 6K + 6K + 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 55,000 BTU 22 SEER2 Four-Zone Ductless Mini Split Air Conditioner System - 6K + 6K + 6K + 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 55,000 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.

The Excellence of Motion Preserved
Style: Full Synthetic High Mileage, Size: 1 qt (Pack of 1), Configuration: 5W-30
In the pursuit of the ideal, where reason governs and the forms of all things aspire to perfection, the Valvoline Full Synthetic High Mileage with MaxLife Technology 5W-30 Motor Oil presents itself as a manifestation of virtue within the mechanical realm. It is not merely oil, but a substance designed with foresight, sustaining the engine as the soul sustains the body. The viscosity is measured, neither excessive nor deficient, allowing parts to move in harmonious accord, reducing friction and preserving integrity. One observes that engines treated with this oil respond with steadiness and endurance, as if guided by a rational principle, minimizing wear and extending life in a manner that reflects the pursuit of the Good. I grant it five stars, for it exemplifies a balance between strength and refinement, a practical embodiment of foresight, wisdom, and care—ensuring that motion, that vital energy, continues undisturbed, much as a well-ordered soul achieves its fullest expression through the contemplation of virtue.

Extraordinary resource
Format: Paperback, Format: Paperback
I am a Cultural History Interpreter in SC. Working at a plantation historic site to bring suppressed history to light is challenging. Prof Sinha's book gives us easily accessible documentation to counter the "Lost Cause" devotees who appear on the site almost daily. Her writing style is clear and lucid, a trait for which I am extremely grateful. The site is including this volume in our staff library. For those just entering the field of Public History, it is indispensable. For the rest of it is a very valuable resource. Highly recommended!

An important contribution
The historiography of secession is a complex one. For much of the last century there had been a tendency for historians to underplay the importance of slavery as a cause of the American civil war. Certaintly neo-Confederate apologists have sought to euphemize the cause of the conflict to an issue over tariffs, to matters of states rights, or to the "extremism" of the abolitionists. It is quite clear that these excuses will not survive a reading of this book. Sinha clearly shows, in her examination of South Carolina secessionism from nullifaction to fort Sumter, that slavery was the essence of its concerns. To show this she looks at the nullification crisis, the Mexican war, the Compromise of 1850, the South Carolinian movement to reopen the slave trade, and the secession crisis, based on exhaustive research of no less than 137 sets of private papers and diaries. But Sinha wishes not simply to refute the academically unimportant group of neo-Calhounites. She wishes to argue something broader. The South Carolinian defense of slavery was not, as many serious historians suggest today, simply the working out of the Southern American view of liberty. Increasingly, Sinha argues, South Carolina pro-slavery thought was not the expression of Southern Republicanism, but increasingly its very negation. It was not a coincidence that secessionism was strongest in South Carolina, the only state by 1832 where presidential electors and the governor were not popularly elected, where the legislature was crudely malapportioned, and where local offices were limited by the state government. It was also not a coincidence that slaves were a majority of South Carolinians, and slaveholders nearly a majority of South Carolinian whites. And it certainly was not a coincidence that non-slaveholders were noticeably less enthusiastic for nullification, secession in 1851 and secession in 1861. But although Southern nationalist discourse was clearly elitist and pro-slavery, does Sinha show that it was counter-revolutionary? A certain opposition to democracy was evident after all in the many, perhaps most, of the founding fathers. But as Sinha points out leading Carolinians like Calhoun, Senator James Chesnut and the creepy, incestuous James Hammond all sneered at the Declaration of Independence. She quotes one bravado warping PatricK Henry to declare "Give me Slavery or give me death." Notwithstanding the views of some historians to the contrary the South Carolinians criticized the North less for its oppression of wage laborers than the possiblity that those laborers could vote themselves into power. They did not condemn Lincoln as an intolerant Protestant but as a dangerous socialist and feminist. Moreover, they were not slow to raise the Nativist card against the immigrants who were bolstering the North's population. Calhoun's idea of a concurrent majority was not a thoughtful protection of minority rights, but a way to prevent one minority, his own, from ever being outvoted. Once the Confederacy was set up the elite dispensed with political parties. Looking at South Carolina they also began to dispense with competitive elections, while its ruthless elite certainly did not act sentimentally (or even decently) towards opinions on slavery. In conclusion there have been many frauds and bullies in American political life: the Nixons, the Hoovers, the McCarthys, the Tillmans and the Bilbos. But much of their malignancy was purely personal and they never threatened the core ideals of the republic. Calhoun was different, very different. Extremely intelligent, he was also utterly principled, and absolutely ruthless in carrying out that one principle. The problem was that the principle, despite all the complications of honor and paternalism, was slavery. More so than anyone else, Calhoun was the greatest enemy of liberty and freedom the United States ever had. Sinha's book is an important contribution to understanding that.
