4. Configurazione e installazione
Follow these steps for proper installation of your filter pump:
- Posizionamento: Position the pump on a stable, level surface near the pool, ensuring it is below the water level for optimal self-priming. Maintain adequate ventilation around the pump.
- Collegamenti dei tubi:
- Connect the hose from your pool's skimmer or main drain to the pump's inlet connection (usually on the side with the pre-filter). Secure with hose clamps.
- Connect a hose from the pump's outlet connection to your sand filter's inlet. Secure with hose clamps.
- Assicurarsi che tutti i collegamenti siano ben serrati per evitare perdite d'aria che potrebbero compromettere le prestazioni della pompa.
- Adescamento della pompa:
- Before starting, ensure the pre-filter housing is filled with water. If not, unscrew the clear lid, fill the housing with water, and replace the lid securely.
- Open all necessary valves to allow water flow from the pool to the pump.
- Collegamento elettrico: Connect the pump's power plug to a grounded electrical outlet. Ensure the outlet is protected by a Residual Current Device (RCD) for safety.
5. Istruzioni per l'uso
Once installed and primed, operating the pump is straightforward:
- Avvio della pompa: Plug in the pump. The pump will begin to draw water and circulate it through your filtration system.
- Monitoraggio delle prestazioni:
- Observe the water flow. A strong, consistent flow indicates proper operation.
- Check the pressure gauge on your sand filter (if applicable). An increasing pressure indicates that the filter needs backwashing.
- Durata: The recommended daily run time for your pump depends on pool size, usage, and environmental factors. Generally, circulate your pool water for 8-12 hours per day to maintain clarity.
- Arresto della pompa: Per spegnere la pompa, è sufficiente staccarla dalla presa di corrente.
6. Manutenzione
Una manutenzione regolare garantisce prestazioni ottimali e prolunga la durata della pompa.
6.1. Cleaning the Pre-filter Basket
The pre-filter basket should be checked and cleaned regularly, especially if you notice reduced water flow or increased noise from the pump.
- Scollegare l'alimentazione: Prima di pulire la pompa, scollegarla sempre.
- Chiudere le valvole: Close any valves leading to and from the pump to prevent water loss.
- Rimuovere il coperchio: Unscrew the clear lid of the pre-filter housing.
- Rimuovi carrello: Sollevare con cautela il cestello del prefiltro.
- Cestino pulito: Rinse the basket thoroughly with a garden hose to remove all debris.
- Ispezionare l'O-ring: Check the O-ring on the lid for cracks or damage. Replace if necessary to ensure a watertight seal.
- Rimontare: Place the clean basket back into the housing, ensure the O-ring is properly seated, and screw the lid back on tightly.
- Ripristino: If necessary, re-prime the pump as described in the Setup section.

6.2. Preparazione per l'inverno
Before freezing temperatures arrive, properly winterize your pump to prevent damage:
- Scollegare la pompa dall'alimentazione.
- Drain all water from the pump by removing the drain plug (if present) and disconnecting hoses.
- Conservare la pompa in un luogo asciutto e al riparo dal gelo.
7. Risoluzione Dei Problemi
Per i problemi più comuni e le relative soluzioni, fare riferimento alla tabella sottostante.
