Hot Spring Watkins Replacement Spas Freshwater III Ozone System Complete, 72602

Pretty easy install. Since the Jacuzzi was empty at the time, all I had to do was cut the line and put it in. There are a couple of install videos on YouTube that you can watch.Works great.

We just bought a Hotspring spa and I wanted to add ozone from the beginning. I searched on YouTube and found several videos showing how easy it was, and decided to give it a try. Fifteen minutes later it was done. My Hotspring HotSpot SX controller did not match with the ozone wire connections shown in the video but it was easy to figure it out after I took a picture of the controller board and zoomed in. The white wire connects on the left side of the board, and the black wire connects towards the top center. Works great and I saved myself about $200.

This is a genuine Watkins Wellness ozone generator. I have use it for about a year. It is much better than the after market generator supplied by my dealer! I have a 250 gallon spa used twice per week and rarely need any sanitizing chemicals or chlorine. The price is significantly discounted compared to dealer retail price.

I didn't realize how broken my old one was until I replaced it with this new one. My Aria hot tub is 7 years old now, and I had never replaced the ozone generator. Installed this new one and wow, what a difference. Its like it was when brand new. That fresh rain smell is back, and the water just feels so much better. If you haven't replaced yours for several years, do it. Worth every penny, and easy to install.

Works great and was an easy replacement for my failing unit. I was replacing a 10 year old unit and luckily most of the tubing and installation from the old unit lined up fine with the new unit. Hardest part was to clamp off the supply hoses while doing the work. Great value.

I found this replacement device to be easy to install. Most people with even limited handyman skills can do this. The thing is expensive but it works like the original

I replaced a three year old unit just like it. Biggest pain was removing and reinstalling the service panel. My hot tub dealer told me ozonators go every two to four years used year round like mine. This was 60% cheaper than buying the same unit through the brick and mortar dealer. Instructions were good. Comes with the check valves as needed. Depending on your layout, it's easy to fit in, but try to clean the existing in-hose T-fitting with a wire before going to all the trouble of replacing it in a very tight space and short main hose. All you really need is the ozonator itself and the new feeder hose, unless your tub doesn't have one already.

The circulation pump on my 2009 HotSpring Envoy recently failed. In addition to replacing the pump, I decided to also replace the ozone system, which stopped working several years ago. I was overdue for a water change, so I decided to do all the work with the spa empty. I suspect this made the work a lot easier (at least dryer). The installation was quite simple; probably took about an hour to remove the old system and install the new. The most difficult part of the job was feeding the ozone tubing behind the control box and up through the ring next to the topside control panel to create an anti-siphoning loop.
