MRCOOL DIY Multi Zone 5th Gen 48K BTU Four Zone Ductless Mini Split with Ceiling Cassettes 6K + 9K + 18K + 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 6K, 9K, and 18K 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 + 18K + 18K offers serious zoned comfort and energy efficiency. The 6K air handler is great for small rooms up to 250 sq ft, the 9K covers up to 375 sq ft, and each 18K unit can handle spaces up to 750 sq ft. Perfect for homes or workspaces with rooms of varying sizes, this DIY-friendly system features a high-efficiency heat pump condenser and four recessed ceiling cassettes for a sleek, unobtrusive look. It’s easy to install without any special tools or HVAC licensing required. Backed by a 7 Year Compressor Warranty (with optional lifetime upgrade) and a 5 Year Parts Warranty.

The MRCOOL DIY 5th Gen 4-Zone 48,000 BTU 22 SEER2 (6K + 9K + 18K + 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 48,000 BTU 22 SEER2 4 Zone Ductless Mini Split System - 6K + 9K + 18K + 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 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 + 18K + 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 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!

Cute, but short-lived
Color: Blue, Pattern Name: Toucan
Santa brought this for our 3-year-old sheepadoodle! Super cute, but she tore it up within a few days. We did like the stretchy neck! She had a lot of fun with it while it lasted.

Best toy, the end
Style: Sport, Size: 12in, Style: Sport, Size: 12in
Combined with the Max Glow ball, this is the best dog toy available on modern planet Earth. I have a burly 92lb. pit bull mix with highly developed prey drive, and she will chase the glow ball for hours if I let her. The tiny sport launcher (Sport 12M) is the best, because you can still throw the ball really far, but you can also slam the ball down a few feet away from yourself so it bounces up in the air and your dog has to jump to catch it, or you can throw it up really high so it bounces 15' away or so and your dog can jump to catch it. We sometimes have to play fetch in a pretty small area, so it's nice to have the small launcher for these games. The larger launchers aren't as fun in small areas. You can play the same games but it's trickier to throw the ball correctly. Also, the small launcher is a lot easier to carry. The small launcher fits in my dog-walk-stuff backpack (with the ball in the launcher so I don't have to dig for it later), but the big ones don't easily. The launcher also has a hole in the end so you can hang it from your bag or whatever with a carabiner. The big ones are too long for that in most cases, and swing back and forth. Also-also my dog loves to ask for the launcher, then when I give it to her she plays keep-away and it's adorable. The big launcher I have is harder for her to balance in her mouth, so she just lays down and chews on it until it gets taken away. She's chewed on all of the four Chuck Its we've owned, but she's only broken one (a big one), but that's because she got ahold of it when no one was home. The little one in my bag is totally chewed up but still works great. I think they're sturdier than the big ones. Except for the launcher she chewed into pieces, which was our fault, the only reason we've had to replace anything was because we lost it. Usually we keep the launcher and ball in the backpack so she can't get to them and so they don't get lost, so we rarely have to replace them. There is just not a better value in toys, and the startup price is really low. Once again I really recommend the glow ball! It doesn't get soggy no matter how wet the grass or the dog mouth is. It is fun to chase because it is slippery and it collapses when it's squeezed, so it pops out of the dog's mouth and flies away if they bite it at the wrong angle; it's really bouncy, and stays bouncy because it can't be popped; it whistles so you can usually hear it even if you can't see it; and it really glows enough for nighttime catch, even if you only have your cellphone flashlight to charge it up! UPDATE: I should have said, we have the 12M launcher, which means the handle is 12 inches long and it uses a medium-sized ball. The medium ball is 2.5 inches in diameter, so the launcher will fit regular tennis balls, too! But my dog won't play with regular tennis balls anymore because they aren't anywhere near as fun as the glow balls, and I think she doesn't like having gross sloshy muddy tennis balls in her mouth. I lost my short launcher awhile back and could only get a long one locally to replace it, which reminded me that you have to lean over a lot further to use the short launcher. So if you have trouble leaning over to the point that your hand is a foot above the ground, this may be hard for you to use. I wish Amazon would let us choose colors, because my old one was green, and the big one is orange, both of which are bright enough to see in the grass from far away, even at night. Still, best toy!

Highly recommend.
Style: Sport, Size: 12in
Love this. Dog sitting for a dog that loves to chase balls but my shoulder doesn’t like throwing them. Got this yesterday and it’s perfect. Real arm/shoulder saver. Seems sturdy and I was concerned that a standard tennis ball would not work. We tend to lose balls when walking because this lab insists on carrying the ball in its mouth. They work.

These are awesome and I couldn't play ball with my Dobermans without it!
Style: Sport, Size: 12in
I LOVE Chuckit ball launchers. We've been using for a around 17 years and we've only had to replace one. We have 2 active, energetic Dobermans and I throw like a girl and there is now way I can throw a ball very far. With the Chuckit, I can throw more than 80 feet! My dogs need a lot of exercise and using this ball thrower allows me to make that happen. Bonus is I dont have to pick up a snobbery ball :)
