4. Configurazione e installazione
Follow these steps carefully to set up your sand filter pump. Ensure the pump is placed on a stable, level surface, away from the pool edge, and protected from direct sunlight and rain.
- Posizionamento della pompa: Place the pump on a firm, level surface. The pump should be located at least 2 meters (6.5 feet) from the pool.
- Assemblare la Base: Attach the pump and filter tank to the provided base according to the diagrams in the manual.
- Riempimento del serbatoio del filtro: Remove the multi-port valve. Fill the filter tank with the recommended amount and type of filter sand (not included). Ensure the standpipe is centered during this process.
- Attaching the Multi-Port Valve: Securely attach the multi-port valve to the top of the filter tank. Ensure all seals are correctly seated.
- Tubi di collegamento: Connect the hoses from the pump to the pool's inlet and outlet fittings. The "INLET" port on the pump connects to the pool's skimmer/suction line, and the "RETURN" port on the multi-port valve connects to the pool's return line.
- Collegamento elettrico: Connect the pump to a grounded electrical outlet. Ensure the power supply matches the pump's requirements. Do not use extension cords.

5. Istruzioni per l'uso
Before starting the pump, ensure the pool is filled with water and all connections are secure. Never operate the pump dry.
5.1 Funzioni della valvola multiporta
The multi-port valve has several settings for different operations:
- FILTRO: For normal filtering of pool water. Water flows through the sand, is filtered, and returns to the pool.
- CONTROLAVAGGIO: For cleaning the filter sand. Water flows in reverse through the sand, flushing debris out through the waste port.
- RISCIACQUO: Used after backwashing to flush out any remaining dirty water from the filter before returning to FILTER mode.
- RIFIUTI/SCARICO: For bypassing the filter and sending water directly out the waste port, useful for lowering pool water level or vacuuming heavy debris directly to waste.
- RICIRCOLO: For circulating pool water without filtering it, useful for distributing chemicals.
- CHIUSO: Shuts off all flow to the filter and pump. Never operate the pump with the valve in the CLOSED position.
To change valve settings, ALWAYS turn off the pump first.
5.2 Avviamento della pompa
- Ensure the multi-port valve is set to FILTRO.
- Open all necessary valves on the pool's plumbing system to allow water flow to and from the pump.
- Plug in the pump and turn on the power switch.
- Check the pressure gauge. A rising pressure indicates the filter is collecting debris and may require backwashing soon.

6. Manutenzione
Una manutenzione regolare garantisce prestazioni ottimali e longevità della pompa filtro a sabbia.
6.1 Controlavaggio del filtro
Backwash the filter when the pressure gauge reading is 0.2-0.3 bar (3-5 psi) above the initial clean filter reading, or when pool water flow is noticeably reduced.
- Spegnere la pompa.
- Set the multi-port valve to LAVAGGIO A CONTROLOVANZA.
- Turn on the pump. Run for approximately 2-3 minutes, or until the water flowing out of the waste port is clear.
- Spegnere la pompa.
- Set the multi-port valve to RISCIACQUO.
- Turn on the pump. Run for 30-60 seconds to flush out any remaining dirty water.
- Spegnere la pompa.
- Set the multi-port valve back to FILTRO.
- Accendere la pompa per riprendere la normale filtrazione.
6.2 Sostituzione della sabbia
Filter sand typically needs to be replaced every 3-5 years, depending on usage and water quality. Refer to the specific sand type recommendations for your model.
6.3 Rimessaggio invernale
Before winter, drain all water from the pump, hoses, and filter tank. Store the pump and multi-port valve in a dry, frost-free location. Remove and clean the filter sand if necessary.
