Welcome to our forum.
I am a little confused. You got a CD ozonator from DEL and the UV light is on. What is the model # of the ozonator. Your reference to the UV light being on could indicate that you have a UV ozonator. CD ozonators are electrical charge and discarge systems and do not use a UV light.Secondly, you hared wired it where to what? The Sunzone comes with an unusual plug which is the reason why you hard wired it I am sure, but what circuit did you pick up the 240 volts from? This could be why you have no ICON on the control panel.Thirdly, you could reconsider your decisions, it is possible to create conflicts with the electronics that could cause problems. If they come out to service your spa, your warranty could be voided. did you hard wire to the ozonator plug hook up?
