MRCOOL DIY Multi Zone 5th Gen 48K 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 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 three 6K air handlers are ideal for smaller rooms up to 250 square feet each, while the 9K unit can handle spaces up to 375 square feet. With MRCOOL’s true DIY installation, there’s no need for expensive tools or HVAC professionals — everything is pre-charged, labeled, and built for easy setup. This is a heat pump system, meaning it provides both heating and cooling in every season. The system includes a 7 Year Compressor Warranty with an optional lifetime upgrade and a 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.

The MRCOOL DIY 5th Gen 4-Zone 48,000 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 48,000 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 48,000 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 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.

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!

Excellent RV Extension Cord – Heavy Duty Quality and Best Value for Power Needs!
Size: 25-Foot, Style: 90° Locking End
The Camco Power Grip 25-Ft 50 Amp RV Extension Cord has been absolutely essential for our RV camping adventures! As full-time RVers who frequently encounter campground electrical pedestals that are inconveniently located, this heavy-duty extension cord has solved countless site setup challenges. The 50 amp capacity handles our RV's full electrical load including air conditioning, and the 25-foot length gives us the flexibility to position our rig exactly where we want it. What impressed me most is the exceptional build quality and safety features. The cord feels substantial and professional-grade, clearly designed to handle the demanding electrical requirements of modern RVs. The 90° locking end is genius—it keeps the connection secure and reduces strain on both the cord and the pedestal connection, which is especially important during windy conditions or when other campers accidentally bump into it. The Power Grip handles make connecting and disconnecting so much easier and safer, especially in wet conditions or when wearing gloves. The cord is rated for 125/250V and 12,500W, giving me complete confidence that it can safely handle our RV's maximum electrical demands without overheating or voltage drop issues that can damage sensitive electronics. For such a heavy-duty, professional-quality 50 amp RV extension cord with excellent safety features, the price was absolutely the best value I found anywhere. RV dealers charge much more for comparable cords with fewer features. I'm very likely to buy a second one as backup and have recommended it to fellow RVers in our camping group. This cord has made campground electrical connections so much more convenient and reliable! Solid 5 stars!

Great power cord
Size: 25-Foot, Style: 90° Locking End
I'm very happy with the quality of this power cord. The one that came with my RV came straight out of the side and 50 amp cables are heavy. This cord has a 90 degree end that takes away the leverage factor of the other one. This should be much easier on the RV wall connector. Well worth the cost.

Good RV Power Supply Cord
Size: 25-Foot, Style: 90° Locking End
It's an overall good value for the cord. I purchased so I'd have a spare in the rv and because my original is very short, I may need the extra length one day. I plugged it in and it works as intended, it appears to be good construction and quality materials. I've been caught in a situation before where my cord went bad (the inlet on the camper overheated and caused the plug in the melt and burn up, this could happen to anyone) it was after hours, so I couldnt run to a store and get one. Had to suffer through the night with no AC and wait until the next morning to go to an RV superstore and pay double what Amazon charges. If you take your rv out alot I highly recommend keeping a spare cord.

Great product! I do not understand why anyone would make or buy any cord without a 90 degree plug-in for their RV.
Size: 25-Foot, Style: 90° Locking End
We had to replace the plug on our RV: The plug was destroyed by the stiff 50 amp cord that; came with our RV that put a lot of pressure on the plug-in on our RV causing it to arc and melt both the male and female where the cord was plugged into the RV. . The heavy duty 90: degree end has a soft flexible cable and greatly reduces the stress on the RV plug. I expect this cord will last much longer. Would recommend this cord to anyone. I do not understand why anyone would make or buy any cord without a 90 degree plug-in for their RV. Dealers may not have this item in stock.
