- Filter Cleaning: Periodically check the filter washer located in the inlet connector for debris. Clean it under running water if necessary to ensure proper water flow.
- Battery Replacement: Replace batteries when the LED indicator shows a low battery warning or if the unit stops functioning. Always use fresh AAA alkaline batteries.
- Winter Storage: During winter months or periods of freezing temperatures, disconnect the programmer from the tap and store it indoors in a dry, frost-free location. Remove batteries before storage.
