Jacuzzi Ozonator
« on: February 16, 2006, 07:13:04 pm »
Now that the tub is clean I decided to re-read the manual and check my programming since the power was off for a prolonged period.

It didn't need any changes but I noticed that the ozonator bubbles are larger than before and SWMBO says it gurgles now.  She is right on both counts.

But I think the real issue is that the dealer told me the ozonator ran continuously, but the symbol on the control panel that indicates it is working is not on continuously.

SO...  ???

1. Is the ozonator supposed to be running continuously?

2. Does the existence of bubbles mean the ozonator is working?

3. If #2 is no, what the heck are the bubbles for?

Bigger bubbles = new water, as far as gurgling it's possible that air is trapped and needs to worked out. How you do that depends. I've turned off and on the tub a couple of times or you can try to open the diverter valves on top of the tub with the pumps off and see if any air escapes.

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.

This must be it.  While I was progamming I turned a couple pumps on.  The ozonator shuts off when the tub is used and probably has a time delay before it comes back on.  The bubbles threw me for a loop until you two explained it to me.  Thanks.  All is well in tub-land.

Interesting, my dealer explained to me that my Artesian has all the pumps interconnected (1/2" tubes on pump head) and if one pump gets an air lock opening up the diverter valve could get rid of the air lock. I've seen other people here say the same thing on different brands so I did assume this was true with all brands

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.

Where would the ozone symbol appear?  I have a 2005 j335 and haven't noticed an ozone symbol on my control panel.

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.

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.

My low voltage Circ pump is programmable and is set to run 24 hours beginning at midnight.  It moves water around and puts water thru the heater.

The Ozonator is an option but the Circ pump is not.  But the ozonator is tied into the Circ pump.  When it produces ozone it introduces it through this system.  So if the Circ pump is set to run 2 hours per day, it could only introduce ozone during those 2 hours.  That is why mine (and probably yours) is set for 24 hours.  It is always ready when the ozone is working.

I do think you are correct about the Mazzi injector.  The installer showed me where the ozonator hooks into the Cric system and it looks like the item you described.

Everything evoles ... when I looked at any tub IF they had a 24 hour circ pump, it operation couldn't be changed. Basically when you turned on the tub the pump ran until you turned off the tub.

As far as my tub, I have a huge 240 Volt circ pump and it never stops just like I descibed above. But what I can change is the amount of time the ozonator turns on. My tub can come configured with or without a circ pump, if it didn't have a circ pump then a cleaning cycle would be operating pump 1 at low speed.

Thanks for answering my question!

Ozone is indeed injected via a Mazzei injector in the water line from the circ pump.  The ozonator only creates ozone.  The Mazzei injector creates a vacuum and draws the ozone through the tubing past the check valve into the water where it then passes though a mixing chamber before it all enters the main body of spa water.

The ozonator does indeed shut off when any therapy pumps are turned on indicating there are users in the spa.  Although the ozonator is turned off, the Mazzei injector is still drawing air through the ozonator, thus the bubbles continue to be produced.

Wow.....thanks, Snowbird. I thought that MIGHT be it, but I wasn't sure (saw it on at the store).  If "tiny bubbles" mean the ozonator is on, then it didn't shut off when the one pump was on (I THINK that's pump 2), but the symbol disappeared. couldn't tell if it still bubbled when the other pump was turned on though, too much turbulence...but the more I learn about jacuzzi and this dealer, the more I like what I see.  :)

orlando,  the j-335 does not have an ozone symbol on the topside control, however your ozone does operate when the circ pump is on and shuts off when any hot tub function is activated.

I thought so.  I also know that the ozonator and circ pump won't operate if the water temp is 2 degrees or more above the set temp, which happens a lot in the Florida Summers.

Is there a way to know if the ozonator is working on the j335 dpgtech?  I'm still not convinced on the benefits of the ozonator but would like to know anyway.
