Before ordering

Confirm the model, year, and equipment of your Hot Spring or Caldera spa. Having a salt system does not by itself mean the spa can use the IQ sensor.

Setup

Follow the manufacturer's replacement and initialization procedure. Monitoring helps you choose adjustments; this sensor does not dispense chemicals.

The sensor does not replace additional water testing. Follow the chemical restrictions in the IQ manual, particularly for silver, ozone, bromine, and MPS.
