Installing a self contained ozonator - no plumbing required

Posted by on 5/18/2023 to How-to

Electrical requirements :

Ozone can be delivered continuously, up to 24 hours per day, when wired independently of the spa pump by simply plugging it in into a regular (nema) receptacle. Or you can wire to the low side pump circuit in the control box, for controlled operation.

Installation requirements :

The self contained ozone generator can be mounted anywhere in the equipment area, or it can be mounted to an outside wall. If you are mounting it in the equipment area, make sure the check valve is installed and a "Hartford Loop" (Fig 1) is installed to prevent water from backing up into the ozonator. If the unit is going to be mounted on an outside wall, place the unit above water level, this will prevent water from siphoning into the ozonator.

Connect a 6" piece of tubing to the barbed fitting, at the other end install the provided check valve. Once this is done, blow into the check valve, the air should flow freely towards the tee, if you feel back pressure when doing this, you have the check valve installed backwards.
Attach a 5-6 foot length of flexible tubing to the check valve and route the hose so that at some point it passes above the water level of the spa. You may need to tie the hose up to keep it in place. This will help insure that no water backs up into the ozonator. (Fig 1)

For temporary or simple installation, slide the ozonator tubing onto the barbed wall fitting and let it hang over the edge into the spa water.
