IMPORTANT: The platinum coating on the cell plates may not last as long with quicker change
over times as a percentage of wear on the coating is related to the number of polarity

• Press and hold the “DECREASE” button.
• Turn the unit “ON”.
• Release the button and the selected reversing time will display. The default will be set to 7

one reversing hour to another.
