This manual provides essential information for the safe and efficient setup, operation, and maintenance of your sand filter pump. Sand filters are a popular choice for pool filtration due to their effectiveness in removing small particles and their long-lasting sand media, which typically requires replacement only once every five years.

This pump features a versatile six-function control valve, allowing you to filter, backwash, rinse, recirculate, drain, and close the system. It also includes a built-in 24-hour timer for automated operation and a safety shut-off for enhanced convenience and safety.

5. Instruccions de funcionament

The 6-way control valve allows for various operational modes:

• Filtre: Normal filtering mode. Water passes through the sand media, removing debris.
• Rentat a contracor: Cleans the sand media by reversing water flow. Perform when pressure gauge indicates high pressure (e.g., 14-16 PSI).
• Esbandida: Used after backwashing to flush out dirty water from the valve and settle the sand.
• Recirculate: Bypasses the filter, circulating water without filtering. Useful for chemical distribution.
• Desguàs: Drains water directly from the pool.
• Tancat: Shuts off all flow to the filter. Use when performing maintenance or opening the strainer basket.

Temporitzador de 24 hores: The built-in timer allows you to set the operating time for the pump. To set the timer, turn the pump on at the desired start time and select the duration (e.g., 2, 4, 6, 8, 10, 12 hours). The pump will automatically run for the set duration each day.

6. Manteniment

Regular maintenance ensures the efficiency and longevity of your sand filter pump.

• Rentat a contracorrent: Perform backwashing when the pressure gauge reads 5 PSI above the initial clean pressure, or when water flow significantly decreases. Backwash until the water in the sight glass runs clear (typically 1-2 minutes).
• Esbandida: Esbandiu sempre durant 30-60 segons després del rentat a contracorrent per assentar la sorra i evitar que l'aigua bruta torni a la piscina.
• Substitució de sorra: The filter sand typically needs replacement only once every five years.
• Neteja de la cistella del colador: Regularly check and clean the strainer basket to remove leaves and large debris. Ensure the pump is off and the control valve is in the 'Closed' position before opening the strainer lid.
• Hivernització: Before freezing temperatures, drain all water from the pump and filter. Store the unit in a dry, protected area.
