Very easy to use semi-automatic dosing to maintain the pH or chlorine level of a home pool:Set the hourly dose amount.
Set the knob to the 12 o'clock position on the dial.
That’s it done!
You can turn the knob to increase or decrease the hourly dose by up to 50%.
You can set a Shock Dose and the pump will run for ten minutes and then revert to its normal programme.
