The ozonator just unplugs from the bottom of the IQ control box in the motor compartment. The injector is installed in the 3/4" plumbing lines however and you will still get air coming up from the bottom unless you take it out or crimp off the air intake line. You will not damage anything if you do any of these things.
It appears that there has been no ozone injector installed in my Jetsetter J. Although the manual shows it, in my equipment cabinet, the output hose from the he heater has an instruction sticker on it saying that the unit is pre-plumbed for an ozone injector, and to install, cut the tube as indicted-- no ozone injector, just installation instructions. Am I missing something, or did this unit get shipped without an ozone system? The original owner bought this unit from the showroom as a floor model. Again, thanks in advance for your help with this!
