5. Funtzionamendua
The 7-way multi-port valve allows for various operational modes. Always turn off the pump before changing valve settings.
- Iragazkia: For daily filtration and pool cleaning. Water passes through the filter media and returns to the pool.
- Atzerako garbiketa: Reverses water flow through the filter to clean the filter media, sending dirty water to waste.
- Garbitu: Used after backwashing to flush out any remaining debris from the filter before returning to filter mode.
- Hondakinak: Drains water directly from the pool to waste, bypassing the filter. Useful for lowering water levels or vacuuming heavy debris.

- Birzirkulatu: Mixes pool water without filtering. Water bypasses the filter media and returns directly to the pool.
- Negua: Used for winterizing the filter system. Turn off the pump and open the valve to this position.
