Welcome to our forum.
Just so you know Chris, Coleman carries a 5 year warranty on it's ozonator. Guess they don't care how long their's last, they just care that the customer gets taken care of.
Here it is...factory installed ozone generators (including generator, transformer, and injector),
I feel a little ignorant asking you this but is changing the bulb or chip something the customer can do, or does it require a tech.
but expecting to be able to walk a client through a process like this could freak comeone out.
