I verbally spoke to the tech about what was the correct unit to replace my 20+ year old recently burned-out control board and she was very helpful. The installation was easy and straightforward. A month later it stopped working so I called for tech support and Amy stepped me through the troubleshooting and now we are fully functional again. Vibration must have loosened one of my power connections and I had missed that check before calling. She was very patient and knowledgeable. She didn't make me feel stupid as it ended up being a very simple issue to resolve.
This is the second HCD-55 we purchased from Spa Depot. The first lasted exactly 3 years. The output is high and makes a clear difference in our environment and setup.
We've purchased various ozonators for our Hot Springs spas since 1998. We're sticking with this model.
I installed it a few days ago. It seems to be working well-lots of ozone bubbles! I did have a technical question about the wiring, and the person I spoke to had the right answer and eliminated the hesitation I felt about doing the install. Good product and good customer service!
The ozone generator works. But when you look through the translucent case you can see that it's almost twice as large as it needs to be. The case has a lot of empty space. This larger size means this ozone generator cannot be located in good location inside my spa. Had the case been made closer to the size needed to enclose the working bits it probably would fit.
Great product, but I can't find any videos how to install it
