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!

Excellent Quality Wire Lugs and Adhesive Heat Shrink Set
Size: 2/0 Awg - 3/8" (M10) Ring, Number of Items: 10
I recently purchased the 10pcs 2/0 AWG-3/8" Wire Lugs Ring Terminal Connectors along with the 10pcs 3:1 Dual Wall Adhesive Heat Shrink set from Amazon and I must say, I am thoroughly impressed with the quality and performance of this product! Firstly, the wire lugs are exceptionally well-made with heavy-duty materials. The copper construction ensures excellent conductivity, making them ideal for various electrical applications. The 2/0 American Wire Gauge size with a 3/8" ring terminal is perfect for my specific needs, and they fit securely on the cables, providing a reliable and sturdy connection. The wire lugs come with the corresponding 3:1 dual wall adhesive heat shrink tubes, which are an excellent addition to the set. These heat shrink tubes offer superior insulation and protection, making sure that the connection is secure and insulated against any potential damage or short-circuiting. The adhesive lining within the heat shrink tubes ensures a tight and waterproof seal, further enhancing the reliability of the connection. I found the installation process to be straightforward and hassle-free. The wire lugs are easy to crimp onto the cables, and the heat shrink tubes shrink perfectly around the connection using a heat gun. The adhesive within the heat shrink tubes bonds effectively, leaving no room for any moisture or contaminants to compromise the connection. Overall, I highly recommend the 10pcs 2/0 AWG-3/8" Wire Lugs Ring Terminal Connectors and 10pcs 3:1 Dual Wall Adhesive Heat Shrink set. The quality and performance of this product exceeded my expectations. Whether you're working on automotive projects, marine applications, or any electrical wiring projects, this set will undoubtedly fulfill your requirements. It's a fantastic value for the price, providing reliable and secure connections. I'm extremely satisfied with my purchase, and I will definitely be purchasing more in the future for my upcoming projects. Don't hesitate – give this product a try, and you won't be disappointed! Disclosure: I received no incentive or compensation for providing this review. My review is based on my personal experience as a customer.

Very nice battery lugs. They are not thin junk & they fit. I used a hydraulic crimper which gave me an excellent crimp. Well worth the money.
