15.4 Ozone water maintenance system (Optional)
This system is optional on North American models and standard
equipment on export 50 Hz modes. If you spa is equipped with the
Jacuzzi CD ozone water purification system you will find that your water
stays fresh and clear with significantly less chemical usage. You will
probably be able to go longer between complete spa drainings.
note: To maximize sanitation benefits from this product, always turn off
the spa waterfall valve when the spa is covered or not in use. This setting
ensures maximum water flow through the ozone injector and higher
ozone concentrations. The ozone only runs when the circulation pump is
running and shuts off when either jets pump is manually activated during
spa use. The circulation pump will remain off for 5 minutes after both jets
pumps time out or are manually turned off, then resume operation as
programmed.
