Fungi Posted March 11, 2011 Report Share Posted March 11, 2011 Tub: Jacuzzi J-345 50th anniversary model Capacity: 336 gallons Ozonator: Yes Jets: 27 Power: 240vac @ 60amp, can run pumps and heater at same time. Circ Pump: Yes Use: Year round, once every weeknight, sometime twice a day on W/E by two clean average size naked humanoids. Last week we had a storm and it killed my outside light and my Jacuzzi's ozonator. I was chatting with the Jacuzzi support guy. He told me the ozonator originally used on my tub had a problem of gunking up with brown acid, and they now install a new design that does not have that problem. I asked him for the part number but he could not find it. I am an Electronic Engineer and can replace this myself, but I have no idea what to get. Can anyone shed some light on this problem? The ozonator it has now is a blue box smaller than a shoe box. Two ports, one unconnected and one with a long 1/4" tube. There are two check valves, with a flow restrictor between them, and then it connects to a fitting on a larger tube. Help me please. I don't trust it without the ozone. Thanks, Jim Quote Link to comment Share on other sites More sharing options...

Thanks, Jim I used to really like the CD type ozone generators until I found that they were less forgiving when circ pumps failed, check valves failed, etc, etc which stopped the flow of air thru the units and causing early failure of the ozone generator. Now unless the customer is adamant about having a CD unit, I push the Prozone PZ-1 as a very inexpensive but trustworthy UV ozone generator which has a 2 year warranty and should be replaced every two years for optimum performance.

Fungi Posted March 15, 2011 Author Report Share Posted March 15, 2011 I used to really like the CD type ozone generators until I found that they were less forgiving when circ pumps failed, check valves failed, etc, etc which stopped the flow of air thru the units and causing early failure of the ozone generator.

Help out a guy with the terminology. I assume I have a CD one now. It used to make a high pitched noise. So the UV one, does it kill by running water past the light, or does it still make bubbles? This is so frustrating. Called Jacuzzi tech support. Told them my ozonator went out. The guy tells me "they are using a new one now that doesn't gunk up with brown acid." However he later told me the tech would not give a part number! Told me to go to a dealer... So, no part number, not even a description. Why is it when it comes to hot tubs, no one seams to have any freaking idea what the hell they are talking about! Quote Link to comment Share on other sites More sharing options...
bdubya200 Posted March 15, 2011 Report Share Posted March 15, 2011 He prob wants you to pay the delaer price for it, rather than googling the part number and paying the online price for it. Quote Link to comment Share on other sites More sharing options...
ChaiSTi Posted March 16, 2011 Report Share Posted March 16, 2011 ^agree Manufacturers are trying to support their dealers as much as possible. This helps keep both of them in business. Quote Link to comment Share on other sites More sharing options...
bdubya200 Posted March 16, 2011 Report Share Posted March 16, 2011 I understand that. Doesnt mean I still wouldnt research the part in question and seek another avenue for purchase if possible . Quote Link to comment Share on other sites More sharing options...
Fungi Posted March 17, 2011 Author Report Share Posted March 17, 2011 Hey I was so frustrated I called the guy back. After further prodding I was able to get to the bottom of this. I swear some tech support people have little knowledge of the English language. They didn't switch to a new magic system that does not have the gunking up problem... Rather they changed the way it's configured. They no longer put the restrictor on the output of the ozonator, they instead put it on the input side. No brainer when you think about it... He also shared the part number. 6473-124A. So there it is. Mystery solved. Pfft... New ozonator system indeed. lol Quote Link to comment Share on other sites More sharing options...
ChaiSTi Posted March 18, 2011 Report Share Posted March 18, 2011 The restrictor is problematic. If bubbly noise is not an issue, I would just get rid of it. Quote Link to comment Share on other sites More sharing options...
Fungi Posted April 12, 2011 Author Report Share Posted April 12, 2011 I bought a new ozonator and installed it, no problem... I had one of the restrictors left over so I stuck it on the input side of the ozonator. It makes the bubble smaller ad I can tell you it's not going to clog. I'm happy!
