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.

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.

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 product for the price.
Style: ET-4800, Color: White, Set: FAX/ADF/Print/Copy/Scan
I have had many, many printers over the many years at the business and for home. I honestly think this is the best value for what I need. The eco tank is fabulous. This is the first printer I have purchased with the ecotank. So much better than the cartridges. The quality is good and it was easy to setup and put on the network. I did wait a few months before writing this review to truly test it out and write a fair review. I am pleased. I have had Epson products in the past and do appreciate their quality and affordability.

JUNK, Cheaply built, Feed Scanner fails and falls apart in less than 5 months and only 4 uses.
Style: ET-4800, Color: White, Set: FAX/ADF/Print/Copy/Scan, Style: ET-4800, Color: White, Set: FAX/ADF/Print/Copy/Scan
Absolute piece of Junk! Built cheaply. Feed Scanner has never worked properly from my first scan (only did 4) and now falls apart completely, in the roller section. It falls out after it jammed for the 7th time today, this time with a SINGLE piece of paper. If you have a piece of paper that has a fold in it, forget about it. That will never feed through. I had 6 sheets I had to get out today, I had to do manually via the flat bed, both sides. It took 23 minutes to get done. Should not have taken 2. The last time I used it same issues but less sheets. The paper is SO TIGHT in the feed section it is hitting BOTH walls. You could not slip a piece of paper in there if you wanted too, most likely one of the reasons it does not feed correctly. While on the phone with support (I am right now, 4th call today and 3 emails of pictures they wanted later, the hoops they put you through is ridiculous!) Of course overseas support and has little to no knowledge of being Tech support, I asked for supervisors only to have my first call disconnect at 1 hour and 20 seconds. Then the next call was 24 minutes, then another 32 minutes and now this one still ongoing (56 minutes and still going). Now after 3 hours and 5 minutes, they are "holding" my credit card for 179.99 + tax to get a REFURB unit! So much for a 5 year Warranty. Oh they acted like it was out of date on Warranty, it has NOT been in EXISTENCE for 5 years , it came out in 2022. Did I fail to mention you WILL be dealing with Overseas people who have you repeat the same thing over and over and over and over again. They wonder why I was getting upset...hmmmm . As they pass you along the ranks you have to repeat EVERYTHING all over again. As I was on the phone and they were asking me to open WRONG doors to find the serial #, I lifted once again the Jam area and guess what, the parts fell out. Just PLOP! Other issues while I am at it, the Picture quality is "OK" nothing special. I bought it to save ink as HP gouges you to death and destroys your print head if you use a knockoff. The Ink has been "OK", but I haven't really had it long enough to tell as most everything has been Black and White, so all are still full except the Black (3.4's). Its a rear feed, I miss the HP draw on that, the print speed again is not fast, just OK. Though never really in a rush with it. I cant say it enough, this is cheaply built, and my experience with Tech Support was a HORRIFIC. I never like dealing with Over seas support as it is, but what they wanted pictures of as proof was mind blowing (pictures of the tubes that go to the ink wells? What does that have to do with the issue at hand.) The panel function is anything but user friendly. Firmware Updates, if not done, will prevent usage until done. You have to download and install ALMOST 30 different files, from drivers to firmware updates the list is endless. Never have I had to do that many of ALL printers I have had combined. Simple ZIP file and let it run on an executable file (EXE)like everyone else. That will take you over 2 hours to get all loaded. The ink wasn't bad seeing it needs to be primed first to work, I am not sure what will happen when the REFURB comes, will I get ink or just have to re-prime from the cartridges. The software for scanning is easy to use, though unnecessary, should just scan and auto save, or am I just spoiled by HP? But to send me a "REFURB" as a replacement on a 5 month old unit with a 5 year warranty is really being low. They did EVERYTHING they could to get me to NOT follow through in this return, you have ONLY 30 days on Amazon. You have been warned, I would look elsewhere, the tank issue is a great Idea, but if it doesn't work, what good does it do.

First Impressions - Complete Review
Style: ET-4800, Color: White, Set: FAX/ADF/Print/Copy/Scan, Style: ET-4800, Color: White, Set: FAX/ADF/Print/Copy/Scan
Printer Review from an Artist. Printer cost with a 3-year extended warranty - $199.00. Came with four full bottles of Ink. Each bottle was huge, and enough to completely fill up the tanks. In my old Epson printer that used Epson 127 Ink Cartridges a cartridge held 8ml of ink. The cost per cartridge for the XL Black was $31.00 on Amazon. In comparison, a bottle of ink for the tank printer costs $15.00 and holds 65ml. The Epson 127 Ink Cartridge is rated at 175 pages for the XL cartridge and the Tank Printer is rated at 4500 pages per bottle of ink. So, the difference in cost is striking. Unboxing the printer was simple enough. The printer weighs about half the weight of my old Epson printer. The new printer does not have printer drawers but, back feed only. This actually worked out well for me since I was constantly taking the paper in out and out of the drawers when changing paper size. Also, with this direct paper feed, I figure it will handle my heavier weight card stock paper that I use for my art and greeting cards. To my great surprise, the printer offers two-sided printing. This is really handy when printing my Zines. The printer setup was extremely easy as they recommend a phone app, that walks you through each step with pictures. And it communicated perfectly with the phone for the setup. It takes about 15 minutes to completely set up the printer. I have learned to not rush setup. Take your time, and follow the instructions step by step, Which include filling the tanks. Features, * The printer dues Dual-Sided Print - Great for zines. * It has fax capability, but we do not have a landline, so that will not be used. * It does copying, with a document feeder or you can lift the feeder and place the document on the glass. * I mostly use my Epson Precision San copier but it is nice if you wish to make a quick copy of a document. * Some reviews complained about the very small LED display but I find that by using the app or computer I can control all that I need to do. Print Alignment. I did this test but the printer heads did not require any alignment. During the setup process, the program installs the printer driver on my computer. However I found it to be the very basic driver, and I went to the Epson Website and downloaded and installed the latest driver which is very robust and has all the settings that I needed. The printer's footprint is smaller than my old printer. And my old printer had two paper drawers, though I never used the second drawer. Negatives. The output tray is flimsy and seems like it would easily break if bumped when I walked past the printer, so I have to be careful about this. So far I do not see a way of checking the ink levels from the computer. And they said in the instructions to be sure to check your ink levels. You can see on the front of the printer, where you can see the ink levels. When you purchase more ink, you can attach the bottle and it will not overfill the tanks, and you can then use more ink from the bottle later. So I will purchase a complete set of ink and keep it and as it runs low with about 1/4 left in the tank, I will just fill it up. So far I am very happy with the investment and now printing and ink cost is not a major factor. And I figure I will do a lot of printing with this printer when the holiday season rolls around for my greeting cards. As for print quality, I will need to report on this later, though there were no negative reviews of print quality. A test print on regular paper and the colors seemed to be spot on. One note, I still will continue to use my Canon Pro-300 Wide Printer for my Fine Art Prints, but the new Tank Printer will be my studio workhorse.

Frustrating to set up and unreliable
Style: ET-4800, Color: White, Set: FAX/ADF/Print/Copy/Scan
I bought the Epson EcoTank ET-4800 hoping for an easy, low-cost printing solution, but it has been nothing but trouble. The wireless setup is overly complicated, and the printer often loses connection to the network, forcing me to restart it or reinstall the software. Printing is slow, even for simple documents, and the paper feeder sometimes pulls multiple sheets at once. While the EcoTank system is supposed to save money on ink, the print quality is inconsistent — colors can be dull, and black text occasionally appears streaky. Scanning and copying are also sluggish. For the price, I expected something much more reliable.

ET-4800 EZ PZ set up and start up. Prints and scans just fine
Style: ET-4800, Color: White, Set: FAX/ADF/Print/Copy/Scan, Style: ET-4800, Color: White, Set: FAX/ADF/Print/Copy/Scan
An excellent home printer. And why did I purchase such? I had an Epson WF-520 for nearly ten years. But neglect and lack of use caused the printer head to get gunked up. I cleaned the print heads using a solution of 95% Etoh and glass cleaner (about fifty/fifty), a syringe with a plastic tube attached and LOTS of paper towel strips. It was moderately successful but I was never able to get it back to like new printing. I looked over several new printers and wanted to stay with Epson because of ease of use (copy, scanning, printing). Seems as tank printers are the way to go these days. So I ordered the ET-4800. Got here in only a couple of days. Setup was pretty easy, just follow the instructions either via the documentation included or online version. I have pinted and scanned a color test page. I used the built in SmartScan feature without having to think about it much. I am quite satisfied with the results. By the way, there is no automatic two side printing. You actually have to get off your b---, take out the first printing, turn it over and refeed the stack. I was used to doing that with the old WF-520 and never had a problem. I will now set up a once a week, automatic scheduled printing task. I will just have to make sure there is paper on hand. Lack of use is the killer of these inkjet machines regardless of manufacturer.
