Coleman 455, year 2000
220 Volt unit
110 Volt Ozonator
Panel Balboa 400-CA 97 S DLX Millenium

This tub generates ozone when Pump 1 is running on low. The bulb burnt out on the old ozone generating unit and was not replaceable. I replaced the old ozonator with a new unit. It operates properly, generating ozone, until I turn the Pump 1 jets to high. Then the GFI trips.

If I disconnect the new ozonator everything works as it should. Reconnect, it runs until jets are put on high and GFI blows.

I'm thinking the new unit is defective but would entertain other ideas. Thanks.

1. Pull the hose from the ozonator and check to see if you're getting any water there.
2. Did you use the standard plug on the ozonator? or did you have to change any internal wiring to get it to work?
3. Does it trip the instant you push the jets button? Or does the pump run for a second or two or longer, then it trips?

1. No water getting to the unit. I mounted the unit output above the water line and put a loop with the tubing so I didn't expect any to be there.

2. Yes. The spa pack side has a 4 pin AMP receptacle with black/white/blank/green. The new unit is labelled 110/220V and also had a 4 pin AMP plug but that one is black/red/white/green.

3. It instantly trips.

Thank you.

You put ALL 4 pins in that ozone plug?

I ordered the new ozone unit with a 4 pin AMP plug. I called the seller, gave them my spa information, and was told it was 'plug and play'.

If that's what you meant, I'm not sure I understood your question.

Thanks.

Your previous ozone generator, was a 3 pin.

Was it a 115 or 230 volt unit?

You are not supposed to connect all 4 wires to the ozonator.

Use, White and Black and green for 115 - Red is not connected.

Red, Black and green for 230 - White is not connected.

No, the previous ozonator was a 4 pin. A 3 pin AMP connector will not connect to a 4 pin AMP connector. One of the pins on both the panel side and the old ozonator was blank, or empty.

I did change the pin configuration to match the panel side, but the behavior remains the same, GFI trips instantly when high jets are pressed on pump 1.

Thanks.

How many pins are utilized? All 4???

That's odd

I assume Balboa (Control Panel maker) set it up so it could be used for either 110 or 220.

The power side uses three of the four with one empty. The old ozonator was the same. Both Black White Green and Blank. The new unit has a Red to supply the 220, and is marked as both 110 and 220 (actually 120 and 240).

By 'pins', I didn't imply 'sockets'.

The balboa generator has 4 pins supplied with a 4 socket amp connector.

Only 3 of them are supposed to be used.

That said, you didn't respond as to whether or not your previous ozonator was 115 or 230. But for the moment I'll assume the former since that was in your original post - but in the interim, it would be good to at least double check.

Only thing I can think is that something is causing a ground fault within the ozonator when power is removed. Normally when you turn the jets on, the ozonator is supposed to power off.
