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.

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 - 9K + 9K + 12K + 12K + 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.

BOUGHT 2 AND BOTH TERRIBLE
Style: -20-Degree, Size: 50-Foot, Style: -20-Degree, Size: 50-Foot
I bought two of these products 6 months apart from each other (march 2024 and October 2024) both brand new out of the box leaked from this hose connection fitting and is not fixable by replacing the standard hose gasket. Thought maybe it was just the first one was just a dud. It was not, the 2nd one was exactly the same and leaked out of BOTH connection fittings aswell. Yes i tried new gaskets, thread tape / dope, trying to tighten it a bit more, pressure reducer down to abt 35 psi. None of which worked. This product has potential of being good but they used such a low quality connection that it ruins the whole thing. Havent gotten to the point where Ive used it below freezing for more than 1 night so I cant comment on the freeze proofness of it. Tested it with an electrical meter and it uses 690W when plugged in and below the temp rating. I ended up having to repair the hose myself because I couldnt order a chinese brand one instead without running out of time before freezing temps (photographed repair of what is necessary for this to funtion propertly out of the box) but for the price point this hose is at I expect it to last at least 2 years without issues at least, I especially DO NOT expect it to leak being brand new out of the box. If you are going to do the repair you have to carefully cut the insulated sleeve back a few inches without cutting the hose or heated wire and then cut the original hose connector off. At that point you can use pretty much any hose repair threaded connector with a hefty hose clamp nice and tight (dont strip the hose clamp threads though). After spending another 15 min on the repair and $10 in parts you will then have a functional hose for at least 1 week. We'll see how long it lasts now.

Hasn't froze yet
Style: -20-Degree, Size: 25-Foot
Ive been using this for 2 winters now. Its not lost its color, its not kinked, its still rigid and sturdy. It rolls up compact and fits into storage easy when warm. It can be difficult when cold. Easy to use, you just need typical wall power and a water source. Its been buried in nearly a foot of snow and single digit cold and hasn't froze yet.

A 5 year sentence
Style: -20-Degree, Size: 50-Foot
I’ve had this hose for 5yrs and it just sprang a leak and now I need to replace it lol. I’d say that’s pretty damn good for a hose that gets constant daily use. When the weather gets into the sub zeros it does freeze up, even with added heat tape and foam insulation around it all buried about half a foot underground. All in all, even with the freezing I’d say it was a great hose, very durable, not too stiff but a durable firmness, it connected very easily and with the thread tape on it never leaked.

Smart, Well-Built RV Sewer Hose Support
Size: 30-Foot
I’m quickly becoming a fan of Camco products—they’re smartly designed, well-constructed, and a great value. This 30-ft Sidewinder sewer hose support performs perfectly, providing a smooth and stable transition from the RV’s discharge hose to the septic system. I especially appreciate the Velcro storage strap that keeps everything neatly together when not in use. It’s flexible, durable, and easy to handle. Highly recommend this product to any RV owner looking for a reliable and practical hose support solution. Tip: Always get a longer support than your actual sewer hose length so that you can double up the support were needed. The support can never be too long, but too short could cause flow issues during your camping trip.

Light weight and easy to stage!!
Size: 10-Foot
I recently purchased the RV Sewer Hose Support with a collapsible design, and I must say, it has exceeded my expectations in terms of convenience and functionality. Here's my review based on my experience with the product: Pros: Collapsible Design: The standout feature of this sewer hose support is its collapsible design. When not in use, it folds down easily and takes up minimal storage space in my RV. This is a significant advantage, especially in small RVs or when you have limited storage capacity. Stability: I have fully extended the support multiple times, and I'm impressed by its stability. The product doesn't wobble or tip over, even when I have my sewer hose filled with waste. This sturdiness gives me peace of mind, knowing that my hose is well-supported and less likely to leak or cause any mess. Durable Plastic Construction: The choice of durable plastic for the construction of this sewer hose support is a smart decision. The plastic is tough and can withstand the outdoor elements, including exposure to sunlight, rain, and occasional rough handling. I feel confident that this product will last me a long time, making it a worthwhile investment. Cons: Honestly, I haven't come across any significant drawbacks with this product. It has served its purpose exceptionally well, and I have no complaints about its performance. Overall, I highly recommend the RV Sewer Hose Support with a collapsible design. It addresses all the essential aspects you would want in such a product: ease of storage, stability, and durability. The collapsible feature makes it a breeze to pack up, and the stable support ensures smooth sewage flow without any mishaps. The durable plastic ensures that it can handle the rigors of outdoor use, making it a reliable addition to any RV owner's toolkit. Whether you're a seasoned RVer or just starting, this product will undoubtedly make your RVing experience more convenient and hassle-free.
