Helpful instructions.
I haven’t used it long enough to review it on its performance, but the installation instructions were the best I’ve seen. Why? After having purchased three ozone generators over the past three years, this one’s instructions were the first ones to tell me to rout the vacuum line high enough so that water cannot travel back into the generator if the check valve(s) fail. This will hopefully prevent me from having to buy yet another generator soon. I’m happy about the manufacturer giving me this little tip.
