yes the ozone does shut off when any hot tub function is activated such as a pump.
Most if not all tubs turn off their ozonators if a pump key is pressed for a certain time. So if you turned a pump on you probably don't have ozone going.Bubbles should always be present. The venturi that feeds the ozone has air running through it when ozone isn't being produced.
I would not open your diverter valve as that has nothing to do with the circulation pump and ozone system. also there is no venturi that feeds the ozone on a jacuzzi. the venturi's feed only the jets. and yes the ozone does shut off when any hot tub function is activated such as a pump. the exsistence of bubbles does not necassarily mean the ozone is working. you will have bubbles coming out of the circ pump discharge with or without ozone. try resetting the power and don't touch anything, your ozone symbol should appear.
Where would the ozone symbol appear? I have a 2005 j335 and haven't noticed an ozone symbol on my control panel.
As for no venturi, how does jacuzzi inject ozone into the path of water. It has to have some mechanism to get the air to the water. Please explain how Jacuzzi does it. Thanks.
On my 385 it is a circle with radials and a diamond in the center that says "OZONE" under it appearing above the temperature.As I understand it Jacuzzi's 24 hr circ pump runs water thru the heater and ozonator. It is independent of the 3 jet pumps. There is a small outlet in the foot well that produces continuous bubbles. This is where heated water comes out. It gets pretty warm there. I assume it is also where to ozone is injected.
what's an ozone symbol look like, anyhow?
My tub runs the same way ... the only difference between my tub and yours is my manufacturer made the time of how long ozone is introduced adjustable. I can program the ozone to run 24 hours or 2 hours.I was actually asking for the mechanical way a Jacuzzi puts ozone into the tub. I was under the impression that all tubs use what's called a Mazzi injector to get a suction going on the return line, It's like 2 funnels stuck together at the spouts with a air nipple connected at the spouts. As water rushes past that air nipple it creats a suction and sucks the air or ozone out of the tube coming from the ozonator ... this is how my ozonator works.
Here is a scan from my manual. Sorry it is so big. That isn't one of my stronger computer skills.
