I have a 2004 Sundance Altamar with the Sunzone CD ozone system in it. When the heater is on, I see little air bubbles coming up and bursting at the surface.. sorta makes a slight fizzling noise. But how do I tell if the Ozone is still being produced? The original owner I bought the tub from said they only used the tub for 1 season but who knows.. when I take the cover off the tub I really don't smell anything but bromine (well soon to be dichlor since I'm switching right now). My tub is inside my garage too btw.
and how often do you normally have to replace these Sunzone CD Systems?
thanks
The little bubbles at least show you that the Mazzei injector is working and your check valves are not plugged. You should see the bubbles whenever your circ pump is operating. If you only get this while the heater is on, you may be in economy mode and will not get the full effect of having ozone. You should switch to standard mode.
If you open your doors to the equipment area, you should see the ozonator with a 1/4 inch clear tube that extends to a Hartford loop above the water line, then to one or two small check valves and then to the Mazzei injector. You should hear a faint buzz or feel a slight vibration when the ozonator is on. This will tell you that the system is at least running.
There is no good way to check if it is producing ozone except for the smell of ozone when you lift the cover (will be easier to smell with chlorine) or the telltale oxidizing of the pillows and ghosting of the underside of the cover. There is no easy way of measuring ozone in spa water. The Sunzone CD system requires no maintenance and should last about seven years.
