What is the significance of the lights on the power supply of the Model 3100 and 2500?
The significance of the lights is to show you firstly that the power is on, then as the lights increase it is showing you how much power the System is supplying to the array in the bath. The more lights, the more power. As a rule 2-5 lights up is the optimal power, any more than that and you are drawing more power which will put more strain on the System itself. If all the lights come on and start flashing it means your System is drawing maximum power and will shut itself down. The Model 4105 uses a digital readout to indicate the Activity (conductivity) of the water. It is optimal for the Activity (conductivity) of the water to be above 20. You can add a little potassium citrate solution to increase conductivity if needed.
