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 9K and 12K BTU Ceiling Cassettes are protected by a limited lifetime warranty in addition to a 7-year compressor warranty and 5-year parts warranty.

The DIY system includes Quick Connect lines that are pre-charged with eco-friendly R-454B refrigerant.

The MRCOOL DIY Multi-Zone 48,000 BTU 22 SEER2 4 Zone Ductless Mini Split System - 9K + 12K + 12K + 12K 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 - 9K + 12K + 12K + 12K 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!

Comfortable Fit & Great Added Challenge
Size: 8 Lb, Color: Black, Size: 8 Lb, Color: Black
Really impressed with this vest. It fits snug without being bulky and stays in place during walks and workouts. The weight feels evenly distributed, so it’s comfortable on my shoulders and back. I’ve been using the 8 lb option and it’s the perfect way to add a little extra challenge to my routine. Easy to put on, well made, and definitely worth it!

comfortable and works
Size: 10 Lb, Color: Black
Finally figured out how to wear this vest. There are two sides to the vest. When I put it on upside down, it fits much better and is comfortable. I bought the 10lb vest and although it feels heavy when you pick it up, its very comfortable when wearing it. If I put it on right side up it does not fit across my chest. But turned around it fits great and I am able to buckle it closed. I definately stand up straighter when wearing this vest and easy to walk around it. Although, as the weather gets hotter, it is a bit warm to wear.

ONE OF THE BEST ON THE MARKET AND GREAT PRICE!
Size: 24 Lb, Color: Pink, Size: 24 Lb, Color: Pink
I received my 24 pound vest today. I ordered pink. I love the color! Upon inspection, I see that the vest is very well-made, sturdy, with no metal beads leaking. It fits great. My previous vest hung down too low, resting on my hips. This one sits much higher, just like I wanted it too. This fits my body pretty great. I wore it inside my house to give it a try for two hours. It never shifted and I did not have to adjust it. However, the bulging sand pockets on my back, pressed against my shoulder blades and were a little bit bothersome, but not painful. I’m sure I’ll get used to it. I have purchased 5 rucking vests from 4 different manufacturers and this one, along with RuKSTR are the best. Unfortunately, RuKSTR does not make a 24+ lb weighted vest. Here are the stats of my body: 5’9” 142 lbs. 68 yrs old Bust = 38” Waist = 28” Midriff = 30” Top of shoulder to waist = 19” Shoulders end-to-end = 15”

Great work out product
Size: 15 Lb, Color: Black
Zeerun Weighted Vest is most definitely a great product. I am plus-size with large shoulders. This product fits great, the clasp is adjustable, and the padding is soft and comfortable. I don't worry about it holding up. I've been using it for about a month it has great stability, and it's not bulky.

Comfortable fit allows full range of motion
Size: 12 Lb, Color: Purple, Size: 12 Lb, Color: Purple
This is a powerful tool to have in your workout arsenal. The vest is made well; exactly as pictured and described. I ordered mine in purple and thought it would feel bulky and heavy because I struggled with the weight of the box. However, as I took it out of its packing and it unfolded, I felt the weight change. It slipped on easily and adjusting the chest strap went quick and has stayed secure. It feels good on; comfortable, stays in place and does not hinder arm movements. The padding sounds like sand(?) and conform to my body thus avoiding pressure points or places of pain. It does not make me hotter than my workouts normally would, nor does it encourage excessive sweating. I am 100% happy with this vest and as I get stronger I will purchase a heavier one from this company.
