samwise801 Posted June 22, 2020 Report Share Posted June 22, 2020 Greetings! I've got a 2007 Hot Spot Mallorca spa that I'm about to add an ozonator to. The spa describes itself as "ozonator-ready" but its instruction manual says nothing about how to install one. The Freshwater III I've found comes with all its original parts, but I can't be sure about its installation instructions. Something tells me I might be on my own for this one. Has anyone installed one of these units? Maybe even in the same/similar model/year spa? Got any help/advice you can offer before I embark on this project?

samwise801 Posted June 23, 2020 Author Report Share Posted June 23, 2020 Ah, yes, I suppose pictures would help huh. Should have thought of that initially... 😕 Here's my spa's equipment area: And some close-ups of what I believe / assume to be the key components when it comes to the ozonator: So, that white plug that's not currently in use must be for the ozonator. Correct? My bigger question is related to where do I splice in the ozonator's injector. I'm assuming it's that orange-ish tube I'm holding in my hand in the pic above. Is that correct? I can't find any other tubing that would seem to fit the bill. Everything else that's accessible in the compartment there is either for a pump or for a jet, or it's a drain tube or air tube. And my tub does have an outlet on the other side that the manual calls the outlet for optional ozone. I haven't traced that orange-ish tube over to that outlet (I'd have to dig out insulation to do that), but I'm assuming that's where it goes. It seems to match given where the orange tube is in my system and how it behaves when the jets/pumps are on. Is that true? Am I presuming correctly? So, cut that orange tube, fit the injector into it in-line, then run the line from the injector up to the ozonator. Plug the ozonator's electrical into that white plug (hopefully they match!), make a little Hartford loop in the ozonator's line to ensure water doesn't track back into the unit, and that's it?  Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted June 23, 2020 Report Share Posted June 23, 2020 Yep. You are correct. Make sure the injector is facing the right way, there is an arrow on the side that shows water flow direction. I would also recommend an ozone check valve on the injector tube near the ozonator. Quote Link to comment Share on other sites More sharing options...
samwise801 Posted June 23, 2020 Author Report Share Posted June 23, 2020 Great, thank you! I appreciate your help. Any tips for cutting that orange tube? It feels like pretty heavy-duty stuff. I'd love to make sure I cut it nice and straight so it sits all nice-like on both ends of the injector... Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted June 24, 2020 Report Share Posted June 24, 2020 I use a ratcheting pvc cutter, but square cuts are not important, hose clamps are. Quote Link to comment Share on other sites More sharing options...
