I had someone supposedly fixing the heater on my 1999 Hot Springs Bengal and he apparently messed up some stuff in the equipment area. The guy who just came out to correctly install a new heater can't figure out what's happening with the ozone system. He says some of the tubing has been cut, I don't have the constant small bubbles coming up, and there's a loose male plug with no apparent female place to plug it in. He wants to put it back together/correct the mess-up but isn't sure where to start. I haven't been able to find a diagram online that might show where the parts of the ozone system would be (what's connected to what, particularly where this odd male plug connects). Can anyone help me? Thanks in advance.
