Caldera Moorea 120 or 220 volt ozone??

[rphman]

First sorry for a second post. My last post I was concerned about the ozone injector which was answered but know I think I have another problem. I bought a new Monarch CD ozone kit that had the red connector so I ordered the blue one that is correct for my tub but know I read the info on the kit I bought and the seller states it would work in any 120 volt spa, silly me did not read this saw the picture and thought they were all the same except the injector. My spa is set up for 220. Does any one know if there are 2 monarch units?? I googled high and low and can't find any info. As always thanks for the info here!!!

If there is some electrical connector designated for the injector (you mentioned red and blue), get a voltage tester and see what the voltage is at the connector.  Chances are it's 120v.  There's no reason to make an injector that draws 220v unless you live in Europe. The 220 volts coming into the panel in your spa is split inside the control panel to 120V for smaller things like the circulation pump, transformers, lighting and other low draw items.  I would guess the ozone injector would be included in that list.  Usually the only things that run at 220v are heaters and jet pumps.
