Ozone Generator for Cold Plunge, Spa Ozone Generator, Hot Tub Ozone Generator for Home, 50mg/h, FQT-118

I mistakenly mounted my previous ozone too low, and water backed up in it. I needed a replacement, but was trepidatious, because many of the ozone machines on Amazon are not plug and play. They have an AMP-4 plug for a control board. My cold plunge uses a dry box with an inkbird controller and a smart plug. So I needed a 110 standard plug. I took a chance and ordered this ozone machine. It said its 220 or 110. When I got it, I looked at the instructions and saw the wiring diagram, showing the white is ground, the blue is power, and the black or brown is neutral. I removed the cable from my non working ozone, of similar size and power, and wired it according the the included instructions. I used self solder, waterproof shrink sleeves for the connections. IT worked perfectly and powered right up. My cold plunge water was a little murky because my other ozone has been out of commission for two weeks. I have been treating with h2o2, but its not perfect. 1 day of running this new ozone on my inkbird schedule, the water was sparkling clear. There was not a powerful ozone scent, when I opened the lid. However my previous plunge was much smaller, and the new plunge never had a powerful ozone scent with the old Ozone machine either.Anyway, the results are crystal clear water, and that was the goal.If you're like me, dn looking, but concerned about the amp-4 plug, as long as you have some experience with wiring, and can follow the electrical diagram, you should be fine. I did not buy the 3 year extended warranty for $8, but these things don't tend to last that long, so that may be a wise decision. I am sure I'll buy it next time. I figured there was better than even chance I was sending this one back, so I omitted that option. I will, however be keeping this. I love it. Make sure you mount it so that the bottom of the ozone machine, is above the water line in your plunge. I had mine a little lower, and I mistakenly thought the one way valve was sufficient. I realized, when I poured white water out of the tubing, when I was checking why it wasn't working, that it was not the case. Interestingly, the one way valve was also no longer working. I am not sure if water corrupted it, but it would not let air flow in either direction. This new ozone machine came with a new valve, new tubing, and a venturi. So it was plug an play other than the actual plug. Too bad the seller does not offer a simple 110 plug option. At this price point, its the perfect addition for a DIY cold plunge. Not everyone is comfortable with wiring.

Works great.
